Regarding claim 25, Rudolf et al as modified discloses a method of wireless communication (figs. 14-15) at a user equipment (UEs 111-116: the UE includes a transceiver configured to receive first information for first parameters of a first RACH configuration; paragraph 0006), wherein the full-duplex operation is selected in response to the measurement value of the RSRP being greater than the second threshold (the electronic device, in step 1440, validates the RACH occasion (RO) if measured and adjusted value is greater than a threshold denoted as rsrp-ThresholdSSB); paragraph 0187), wherein the half-duplex operation is selected in response to the measurement value of the RSRP being less than the second threshold (note that when the first slot is an XDD slot and the second slot is a normal UL slot, first and second RSRP thresholds are configured for the first and second slots, respectively; a larger RSRP threshold value can be configured for the first slot to account for lower Rx beamforming gains with fewer available TRX for reception in an XDD slot; it means that the measurement value of the RSRP is greater than the second threshold; paragraph 0186-0187, 0190). Note that RSRP threshold can be associated with a measurement based on a received SSB or CSI-RS, where a UE (such as the UE 116) can derive the measurement using one or more samples obtained from one or more measurement instances, the measurement may be averaged or filtered, or an instantaneous sample value may be used (paragraph 0181, 0193).
Regarding claim 26, Rudolf et al as modified discloses a method of wireless communication (figs. 14-15) at a user equipment (UEs 111-116: the UE includes a transceiver configured to receive first information for first parameters of a first RACH configuration; paragraph 0006), wherein the RACH configuration based on the duplex operation and the RACH type are selected simultaneously, or is configured at the UE (a full-duplex UE can transmit and receive simultaneously in symbols of an XDD slot, possibly in presence of other UEs scheduled or assigned resources for either DL or UL in the symbols of the XDD slot; the UE may select a corresponding PRACH group based on measured RSRP value of the synchronization signal block that satisfy the threshold to assist the gNB in determining the repetition number of Msg2 and Msg4 transmission in RACH procedure; a parameter denoted as “prach-ConfigurationIndex” represents the available set of PRACH occasions for transmission of a Random-Access Preamble; a parameter denoted as “preambleReceivedTargetPower” represents initial Random Access Preamble power; paragraph 0164, 0190).
Regarding claims 27, 28, 29, Rudolf et al discloses an apparatus for wireless communication (figs. 14-15) at a network entity (UEs 111-116: the UE includes a transceiver configured to receive first information for first parameters of a first RACH configuration; paragraph 0006), comprising: at least one memory; and at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to: provide a random access channel selection configuration comprising instructions to select a RACH configuration based at least on a duplex operation or a RACH type and further based on a measurement value of a reference signal received power in view of at least a first threshold; provide a synchronization signal block for a user equipment to measure (the UE 116 measures an RSRP for one or more received SSB indices or NZP CSI-RS configurations; paragraph 0186) the RSRP of the SSB in comparison with at least the first threshold (a first RSRP threshold for an XDD slot; note that the physical layer of a UE receives a set of SSB indices and provides the UE RRC sublayer a set of RSRP measurements for SSB candidates with the indices; selection configuration using reference signal received power; paragraph 0145-0146); in addition, a gNB performs UL channel measurement, and a random access preamble enabling a UE to perform random access ; paragraph 0024, 0076, 0103, 0181).
However, Rudolf et al, does not specifically disclose the features of communicating with a network entity based on the RACH configuration selected by a UE based at least on the duplex operation or the RACH type; selecting the RACH configuration based at least on the duplex operation or the RACH type and further based on the measurement value of the RSRP in view of at least the first threshold; providing the SSB for the UE to measure the RSRP of the SSB in comparison with at least the first threshold; and communicate with the UE based on the RACH configuration selected by the UE based at least on the duplex operation or the RACH type,
wherein the RACH type comprises a 4-step RACH or a 2-step RACH, wherein the duplex operation comprises a full duplex operation or a half-duplex operation.
On the other hand, Sedin et al, from the same field of endeavor, discloses the features of communicating with a network entity based on the RACH configuration (receiving a configuration for physical random access channel transmission; performing a random access procedure with a network node and transmitting, to the network node, the PRACH transmission by using the first PRACH resource; transmission of RRC setup request message in 2-step RACH RA type and 4-step RA type, respectively; paragraph 0016, 0130-0131) selected (a UE may select a preamble randomly from a pool of preambles shared with other UEs; paragraph 0084) based at least on the duplex operation or the RACH type (TYPE-1 and TYPE-2 RA procedures ; setting the variable “ RA TYPE” at the UE to indicate whether the feature is requested or not, wherein the variable “RA_ TYPE “has a value indicating 2-stepRA, 4-stepRA, or 4-stepRA-rep based on the determination; paragraph 0024, 0081), wherein the duplex operation comprises a full duplex operation or a half-duplex operation (symbol configured for PRACH can be used for full- duplex transmissions; paragraph 0275-0276), wherein the at least one processor is configured to: select (select SSB being the second or fourth SSB; and determines a PRACH resource, which is associated with the selected SSB and indicates the feature is requested, as the first PRACH resource in response to determining that the feature is requested and in response to the selected SSB being the seventh or eighth SSB; paragraph 0186, 0189) the RACH type after selection of the duplex operation, wherein the RACH type comprises a 4-step RACH or a 2-step RACH (in both 4-step RACH and 2-step RACH, PRACH resources may be selected based on the SSB selection and a SSB to RACH occasion (RO)/preamble mapping; selecting one of multiple SSBs broadcasted by the network node at least partially based on the received configuration and one or more second measurements at the UE; paragraph 0025, 0275, 0277), wherein a second selection of the RACH type (TYPE 1 RA procedure, also known as 4-step RACH, or 4-step RA procedure; and TYPE-2 RA procedure, also known as 2-step RACH, or 2-step RA procedure; paragraph 0081-0083) is based on a second comparison of the measurement value of the RSRP and a second threshold (the UE will first compare UE_SSB_RSRP>rsrp-ThresholdSSB to select the SSB, and then will compare the downlink pathloss reference to determine whether the UE 110 shall select the PRACH resources to determine whether to signal msg3 repetitions or not; furthermore, the SSB selection may be done by combining the SSB selection with a repetition condition for the UE 110 to determine whether a UE shall select an SSB; the RSRP of the selected SSB is higher than the third threshold ; determining that the RSRP of the selected SSB is higher than or equal to the fourth threshold plus the repetition offset; paragraph 0033-0034, 0188-0189). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to apply the technique of Sedin to the communication system of Rudolf in order to provide a method for performing a random access procedure with a network node.
Regarding claim 30, Rudolf et al discloses a method of wireless communication (figs. 14-15) at a network entity(UEs 111-116: the UE includes a transceiver configured to receive first information for first parameters of a first RACH configuration; paragraph 0006), comprising: providing a random access channel (RACH) selection configuration comprising instructions to select (a UE (such as the UE 116) determines and selects an applicable RACH configuration for transmission of PRACH preambles from a set of candidate RACH configurations; paragraph 0189) a RACH configuration based at least on a duplex operation or a RACH type and further based on a measurement value of a reference signal received power (RSRP) in view of at least a first threshold ; providing a synchronization signal block (SSB) for a user equipment (UE) to measure (the UE 116 measures an RSRP for one or more received SSB indices or NZP CSI-RS configurations; paragraph 0186) the RSRP of the SSB in comparison with at least the first threshold (a first RSRP threshold for an XDD slot; note that the physical layer of a UE receives a set of SSB indices and provides the UE RRC sublayer a set of RSRP measurements for SSB candidates with the indices; selection configuration using reference signal received power; paragraph 0145-0146); in addition, a gNB performs UL channel measurement, and a random access preamble enabling a UE to perform random access ; paragraph 0024, 0076, 0103, 0181).
However, Rudolf et al, does not specifically disclose the features of communicating with a network entity based on the RACH configuration selected based at least on the RACH type.
On the other hand, Sedin et al, from the same field of endeavor, discloses the features of communicating with a network entity based on the RACH configuration (receiving a configuration for physical random access channel transmission; performing a random access procedure with a network node and transmitting, to the network node, the PRACH transmission by using the first PRACH resource; transmission of RRC setup request message in 2-step RACH RA type and 4-step RA type, respectively; paragraph 0016, 0130-0131). Note that a UE may select a preamble randomly from a pool of preambles shared with other UEs; paragraph 0084) based at least on the duplex operation or the RACH type (TYPE-1 and TYPE-2 RA procedures ; setting the variable “ RA TYPE” at the UE to indicate whether the feature is requested or not, wherein the variable “RA_ TYPE “has a value indicating 2-stepRA, 4-stepRA, or 4-stepRA-rep based on the determination; paragraph 0024, 0081). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to apply the technique of Sedin to the communication system of Rudolf in order to provide a method for performing a random-access procedure with a network node.
