Claim(s) 1, 10, 23 and 27 is/are rejected under 35 U.S.C. 103 as being unpatentable over Islam et al. (US 2019/0053321 A1) in view of Sarkis et al. (US 2020/0314755 A1).
Regarding claim 1, Islam et al. teach a user equipment (UE), comprising: one or more memories storing processor-executable code; and one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to (Figs. 1 and 12-13, [0197-0198], device 1305 may be an example of or include the components of UE 115 as described above. Device 1305 may include components for bi-directional voice and data communications including components for transmitting and receiving communications, including UE communications manager 1315, processor 1320, memory 1325, software 1330, transceiver 1335, antenna 1340, and I/O controller 1345. The Processor 1320 may be configured to execute computer-readable instructions stored in a memory to perform various functions),
Islam et al. teach monitor for a first set of beamformed synchronization signals comprising a first subset of synchronization information (Figs. 1 and 8, [0012, 0165], the UE to monitor the first set of transmit beams to receive a set of signals from the base station while operating in the DRX mode, the set of signals comprising reference signals, or synchronization signals, or a combination thereof. Beam monitoring configuration component 840 may configure the UE to monitor the first set of transmit beams to receive a set of signals from the base station while operating in the DRX mode, the set of signals including reference signals, or synchronization signals, or a combination thereof),
Islam et al. teach transmit one or more beamformed wake-up signals based at least in part on the monitoring for the first set of beamformed synchronization signals (Figs. 1 and 8, [0064, 0115], each of the base stations 105 and UEs 115 may use a plurality of antenna ports associated with rays to emit one or more transmit beams (e.g., BRSs for beamformed (e.g., beam sweep) data transmission and reception. For example, a base station 105 may use beamforming techniques for downlink (DL) reference signal, wakeup signal, PDCCH, and physical downlink shared channel (PDSCH) transmission to one or more configured UEs 115. Similarly, the UEs 115 may implement beamforming techniques for receive beam training, DL transmit beam selection, and UL transmission including beam recovery signal transmission. Beamformed (e.g., beam swept) data transmission and reception between the UE and base station, in accordance with a DRX configuration at the UE, may include procedures to establish beam selection during wakeup signal procedure, and beam refinement prior to physical downlink control channel (PDCCH) transmission. The wakeup signal may initiate a DRX-On cycle at the UE without including resource allocation or grant information. As a result, the wakeup signal may save decoding resources at the UE and reduce power consumption in comparison to control channel mechanisms),
Islam et al. teach and monitor, in response to transmitting the one or more beamformed wake-up signals, for a second set of beamformed synchronization signals comprising a second subset of the synchronization information (Figs. 1 and 6, [0006-0007, 0149], the UE may be configured by the base station to monitor the beams carrying the set of signals. After transmitting the wakeup signal, the base station may transmit a second set of signals (e.g., reference signals or synchronization signals, or a combination thereof) that may be used for hierarchical beam management. For instance, the base station may transmit the wakeup signal on multiple coarse beams. The base station communications manager 615 may also transmit, to a UE that is operating in a DRX mode, a wakeup signal to wake the UE 115 from a sleep state of the DRX mode, the wakeup signal transmitted using a first transmit beam and a second transmit beam of a first set of transmit beams in accordance with a beam sweeping configuration. In some cases, base station communications manager 615 may transmit a set of signals using a second set of transmit beams, the set of signals including reference signals, or synchronization signals, or a combination thereof, and receive an indication of a transmit beam from the second set of transmit beams, the transmit beam selected by the UE),
Islam et al. teach wherein each beamformed synchronization signal of the first set of beamformed synchronization signals corresponds to a plurality of beamformed synchronization signals of the second set of beamformed synchronization signals (Figs. 1 and 10, [0180], the UE communications manager 1015 may also receive, from a base station, a first set of signals in a first set of transmit beams and a second set of signals in a second set of transmit beams, wherein the first set of signals comprise reference signals, or synchronization signals, or a combination thereof. The UE communications manager 1015 may also select a transmit beam from the second set of transmit beams based at least in part on the received first set of signals. In other examples, the UE communications manager 1015 may also transmit an indication of the selected transmit beam from the second set of transmit beams to the base station).
Islam et al. is teaching the beamforming for synchronization and wakeup signals. Islam et al., however, fail to expressly disclose to transmit beamform wakeup signals. (Emphasis added)
Regarding claim 1, Sarkis et al. teach transmit one or more beamformed wake-up signals based at least in part on the monitoring for the first set of beamformed synchronization signals (Figs. 1-2, [0064, 0089], a base station 105 may use multiple antennas or antenna arrays to conduct beamforming operations for directional communications with a UE 115. For instance, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station 105 multiple times in different directions, which may include a signal being transmitted according to different beamforming weight sets associated with different directions of transmission. In the wireless communications system 200 (e.g., mmW system supporting beamforming), the base station 105-a may transmit wake-up signals 210. For example, the base station 105-a may transmit wake-up signals 210 on a downlink channel 205 (e.g., a downlink control channel). In one example, the base station 105-a may transmit the wake-up signals 210 using a number of different downlink transmit beams (not shown). The base station 105-a may transmit the wake-up signaling to improve the reception reliability at the UEs 115. If the UEs 115 successfully receives one or more of the wake-up signals 210 transmitted by the base station 105-a, the UEs 115 may perform a wake-up procedure and transition to a higher power level to support data transmission and reception. In one example, the UEs 115 may attempt to receive the wake-up signals 210 using a number of downlink receive beams (not shown). In some examples, the UE 115-a may monitor wake-up signaling using a first set of downlink receive beams and the UE 115-b may monitor wake-up signaling using a second set of downlink receive beams).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Islam et al. by incorporating the features as taught by Sarkis et al. et al. in order to provide a more effective and efficient system that is capable of transmitting one or more beamformed wake-up signals based at least in part on the monitoring for the first set of beamformed synchronization signals.

Software 930 may be stored in a non-transitory computer-readable medium such as system memory or other memory.
