Claim 26, Ma teaches a method of operating a first wireless device including two transceivers, the two transceivers including a cellular transceiver and a WiFi transceiver [par 0002, radio communications continuously increases, a radio communication device (such as a smart mobile terminal) is equipped with a variety of radio transceivers that support different radio technologies, and forms a multiple radio terminal (MRT). The MRT may be provided simultaneously therein with a long term evolution (LTE) or LTE- advanced (LTE-A) radio transceiver, a wireless local area network (WLAN) access radio transceiver, a Bluetooth radio transceiver, a global navigation satellite system radio transceiver, etc. The phenomenon of the co-location or coexistence of multiple radio transceivers in a same communication device (MRT) is called in-device coexistence (IDC)]
the method comprising: performing, at the first wireless device, one or more of: 1) identifying resource units (RUs) which are preferred for WiFi uplink (UL) communications for in-device coexistence (IDC) reasons and ii) identifying channels which are preferred for WiFi UL communications for IDC reasons [abstract, par 0082, The method includes: a terminal sets up an uplink scheduling request SR message carrying in-device coexistence IDC information, the IDC information being configured for a network side to allocate an uplink resource to the terminal; and the terminal transmits the SR message. Here, the terminal, based on its own communication state, finds that the WIFI module is also performing related data communication. Then, when the terminal transmits the uplink scheduling request, the IDC information is carried in the SR message to indicate that the terminal is performing WIFI data communication];
and operating the WiFi transceiver in the first wireless device to transmit UL IDC information to a WiFi access point [par 0081, 0082, Step 801, the terminal transmits an SR message carrying IDC information. the terminal, based on its own communication state, finds that the WIFI module is also performing related data communication. Then, when the terminal transmits the uplink scheduling request, the IDC information is carried in the SR message to indicate that the terminal is performing WIFI data communication];
said WiFi access point not having control over resource utilization by the cellular transceiver in the first wireless device but being responsible for scheduling UL resources to be used by wireless devices for WiFi UL communications, said UL IDC information identifying at least one of: i) RUs which are preferred for WiFi UL communications for IDC reasons or ii) identifying channels which are preferred for WiFi UL communications for IDC reasons[par 0082-0086, a network device allocates the uplink resource based on the IDC information and transmits a scheduling response to the terminal. the uplink resource away from the WIFI 2.4 GHZ frequency band means that an RB (a physical resource block) in which the uplink resource is located is the one in the cell that has a larger frequency difference from WIFI 2.4 GHZ over all of the uplink resource block]
said UL IDC information being information that can be used by the WiFi access point when scheduling UL resources for WiFi UL communications to avoid IDC conflicts at the first wireless device [par 0003, 0004, Because of simultaneous operation of multiple radio transceivers of MRT on overlapping or adjacent wireless spectra, when data transmission for a first radio transceiver overlaps in time domain with data reception for a second radio transceiver, the data reception for the second radio transceiver may be interfered with by the data transmission for the first radio transceiver. Some radio resource management techniques are proposed in LTE/LTE-A systems to eliminate the aforementioned interference. An example is to reduce interference with a radio communication signal by disabling other communication signals].
Ma fail to show the network side being a WiFi access point. In an analogous art Banerjea shows the network side being a WiFi access point [par 0036, 0037, 0066, For the stations STA1-STA4 and the AP 110, the one or more transceivers may include Wi- Fi transceivers, Bluetooth transceivers, cellular transceivers, and any other suitable radio frequency (RF) transceivers (not shown for simplicity) to transmit and receive wireless communication signals. An AP may allocate specific or dedicated RUs to a number of wireless devices using a trigger frame. In some implementations, the trigger frame may identify a number of STAs associated with the AP, and may solicit uplink (UL) multi-user (MU) data transmissions from the identified STAs using their allocated Rus].
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings Ma and Banerjea because AP is suitable device that allows one or more wireless devices to connect to a network (such as a local area network (LAN), wide area network (WAN).
Claim 27, Ma and Banerjea disclose the method of claim 26, wherein said UL IDC information includes information identifying RUs which are preferred for WiFi UL communications for IDC reasons [Ma, par 0082, 0084, terminal transmits the uplink scheduling request, the IDC information is carried in the SR message to indicate that the terminal is performing WIFI data communication. After receiving the SR message, the network device allocates the uplink resource far away from WIFI 2.4 GHZ frequency band to the terminal. The terminal utilizes this uplink resource for data transmission, so as to reduce interference with that coexisting radio technology].
Claim 28, Ma and Banerjea illustrate the method of claim 26, Ma fail to show wherein said UL IDC information includes information identifying channels which are preferred for WiFi UL communications for IDC reasons.
In an analogous art Banerjea show wherein said UL IDC information includes information identifying channels which are preferred for WiFi UL communications for IDC reasons [par 0072, 0077, The present disclosure may allow the wireless devices to transmit wireless signals at power levels greater than the PSD limits imposed on OFDMA transmissions, which can increase the range of the wireless devices. For example, by qualifying a wireless device operating in Europe as a frequency hopping device, the wireless device may transmit OFDMA communications on a 2 MHz RU using power levels up to 20 dBm (such as compared to the ETSI's limit of 14 dBm on OFDMA transmissions on a 2 MHz channel).
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings Ma and Banerjea because this provides a Wi-Fi network to increase the wireless range of Wi-Fi devices without violating power spectral density limits imposed by governmental regulations.
Claim 29, Ma and Banerjea provide the method of claim 26, Ma show IDC information is being requested [par 0007, an uplink scheduling request SR message carrying IDC information, the IDC information being configured for a network side to allocate an uplink resource to the terminal]
MA fail to show further comprising: receiving, at the WiFi transceiver, a trigger frame from the WiFi access point indicating that information is being requested; and responding to the trigger frame by performing said step of operating the WiF1 transceiver in the first wireless device to transmit UL information to a WiF1 access point.
In an analogous art Banerjea show further comprising: receiving, at the WiFi transceiver, a trigger frame from the WiFi access point indicating that information is being requested [par 0068, The AP gains access to the wireless medium at time tsub.2, and may transmit a trigger frame 502 to the stations STA1-STAn on a downlink (DL) channel Time tsub.2 may indicate a beginning of a transmit opportunity (TXOP)
508. The trigger frame 502 may allocate a dedicated RU to each of a number of the stations STA1-STAn identified by the trigger frame 502, and may solicit UL MU data transmissions from the identified stations STA1-STAn],
and responding to the trigger frame by performing said step of operating the WiF1 transceiver in the first wireless device to transmit UL information to a WiFi access point [par 0069, 0070, The AP gains access to the wireless medium at time tsub.2, and may transmit a trigger frame 502 to the stations STA1-STAn on a downlink
(DL) channel Time tsub.2 may indicate a beginning of a transmit opportunity (TXOP)
508. The trigger frame 502 may allocate a dedicated RU to each of a number of the stations STA1-STAn identified by the trigger frame 502, and may solicit UL MU data transmissions from the identified stations STA1-STAn. the identified stations STA1- STAn may begin transmitting UL MU data 504 on their respective dedicated RUs. In some aspects, each of the identified stations STA1-STAn may determine whether the frequency band associated with its allocated RU has been idle for a duration (such as a PIFS duration) prior to transmitting UL MU data to the AP)].
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings Ma and Banerjea because this provides a Wi-Fi network to increase the wireless range of Wi-Fi devices without violating power spectral density limits imposed by governmental regulations.
Claim 30, Ma and Banejea illustrate the method of claim 26, further comprising: checking, at the first wireless device, for an actual or potential IDC problem [Ma, par 0062, 0065, the terminal reports the IDC information to the network side, so that the network side schedules frequency domain or time domain of different radio technology communications in a separate manner based on the IDC information, the IDC information includes one or more of: in-device coexistence indication information (e.g., indicating whether there are other radio technologies coexisting with LTE/NR (New Air Interface) within the terminal), receiving frequency domain information of other in-device coexisting radio technologies other than the LTE/NR, receiving time domain information of other in-device coexisting radio technologies other than the LTE/NR, transmitting frequency domain information of other in-device coexisting radio technologies other than the LTENR, transmitting time domain information of other in-device coexisting radio technologies other than the LTE/NR, in-device coexisting time domain allocation information, and in-device coexisting frequency domain allocation information]

Then, when the terminal transmits the uplink scheduling request, the IDC information is carried in the SR message to indicate that the terminal is performing WIFI data communication. a network device allocates the uplink resource based on the IDC information and transmits a scheduling response to the terminal.
Ma fail to show cellular resource grant of RUs or channels which may be used by the WiFi transceiver for UL transmissions
In an analogous art Banerja show cellular resource grant of RUs or channels which may be used by the WiFi transceiver for UL transmissions [par 0074, 0101, In some implementations, if a wireless device is allocated an RU having a number (N.sub.RU) of subcarriers in a wireless network utilizing an 80 MHz channel having a total number (N.sub.tot) of available subcarriers, then the power spectral density (PSD) gain (G.sub.PSD) of the wireless device when transmitting data using a smaller RU (as compared with the allocated RU) may be expressed as G.sub.PSD=10 log 10(N.sub.tot/N.sub.RU). When an RU is initially allocated to a wireless device for UL OFDMA transmissions, the AP may reset its count value to a maximum count value of “15,” for example, because both Japan and Europe consider a wireless device to be a frequency hopping device based at least in part on the wireless device hopping between 15 different channels (or RUs) within a given sequence period];
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings Ma and Banerjea because this provides a Wi-Fi network to increase the wireless range of Wi-Fi devices without violating power spectral density limits imposed by governmental regulations.

The MIMO communications may include single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO) communications. In some aspects, the WLAN 120 may utilize a multiple channel access mechanism such as, for example, an orthogonal frequency-division multiple access (OFDMA) mechanism].

The Wi-Fi devices can receive the determined frequency hopping schedule and the allocation of RUs, and thereafter transmit UL data based on the determined frequency hopping schedule and the allocated Rus].

In an analogous art Banerjea show wherein determining whether or not to respond to the received trigger frame requesting IDC information based on the current IDC status information includes: determining to provide IDC information in response to the trigger frame requesting IDC information when the stored current status information indicates an actual or potential IDC problem [par 0066, 0106, The trigger frame may use association identification (AID) values, assigned by the AP to its associated STAs, to identify which STAs are to transmit UL data to the AP in response to the trigger frame. In some aspects, the trigger frame may indicate the RU size and location, the modulation and coding scheme (MCS), and the power level for UL transmissions to be used by each of the STAs identified in the trigger frame. As used herein, the RU size may indicate the bandwidth of the RU, and the RU location may indicate which frequency subcarriers are allocated to the RU]
and determining to refrain from communicating information in response to the trigger frame requesting IDC information when the stored current IDC status information does not indicate an actual or potential problem[par 0090, Because the first trigger frame 610 has already informed the stations STA1-STA4 of the frequency hopping schedule and has already allocated unique sequences of RUs to each of the stations STA1-STA4 for the sequence period, the second trigger frame 620 may not contain the frequency hopping schedule and may not allocate RUs to the stations STA1-STA4 (such as to minimize the size and transmit duration of the second trigger frame 620)].
