Abstract: A method of a user equipment (UE) in a wireless communication system is provided. The method includes identifying a condition for providing an energy status report (ESR) and determining one or more values of an available energy level corresponding to one or more time instances. A first value of the available energy level, from the one or more values, at a first time instance, from the one or more time instances, is determined based on a first value of a maximum transmit energy level at the first time instance. The first value of the maximum transmit energy level is determined based on the first time instance. The method further includes determining a first ESR comprising the one or more values of the available energy level and the corresponding one or more time instances, determining uplink resources for transmission of a first uplink channel with the first ESR, and transmitting the first uplink channel with the first ESR in the uplink resources.

Abstract: Methods and apparatuses for multiple concurrent random access procedures. A method for operating a user equipment includes receiving first configuration for a random access (RA) procedure, initiating a first RA procedure on a cell based on the first configuration, and initiating a second RA procedure on the cell prior to completion of the first RA procedure. A method for a base station includes transmitting a first random access response (RAR) and a second RAR. The first RAR includes a first temporary cell radio network temporary identifier (TC-RNTI) and a first uplink grant. The second RAR includes a second TC-RNTI and a second uplink grant. The method further includes receiving a first PUSCH scheduled by the first uplink grant and a second PUSCH scheduled by the second uplink grant. The first PUSCH includes the first TC-RNTI. The second PUSCH includes only the first TC-RNTI or both the first and second TC-RNTIs.

Abstract: Apparatuses and methods for random access procedures with multiple transmission reception points or cells in a wireless communication system. A method for performing random access (RA) procedures by a user equipment includes receiving a first configuration for RA. The method further includes initiating a first RA procedure with a first transmission-reception point (TRP) based on the first configuration and initiating a second RA procedure with a second TRP prior to completion of the first RA procedure. A method for operating a base station includes transmitting a first configuration for RA corresponding to a first TRP and transmitting a second configuration for RA corresponding to a second TRP. The first TRP and the second TRP are associated with a same cell.

Abstract: Methods and apparatuses for resource association and link recovery for repeaters in a wireless communication system. A method for a network-controlled repeater (NCR) includes receiving first information for time-domain resources and for corresponding beams for an access link and receiving or transmitting radio frequency (RF) signals on the access link using the beams over the corresponding time-domain resources prior to a link failure event. The method further includes determining the link failure event on a control link (C-link) and performing a link recovery procedure on the C-link. The method further includes suspending receiving or transmitting the RF signals on the access link using the beams over the corresponding time-domain resources during the link recovery procedure.

Abstract: Apparatuses and methods for ON-OFF indication for repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a first time-domain resource and for a corresponding first beam for an access link of an NCR forwarding (NCR-Fwd) entity and second information for a second time-domain resource and for a corresponding second beam for the access link of the NCR-Fwd entity. The first time-domain resource overlaps with the second time-domain resource in a first set of symbols. The first time-domain resource is not associated with a priority flag. The second time-domain resources is associated with the priority flag. The method further includes receiving or transmitting a first radio frequency (RF) signal on the access link using the second beam over the first set of symbols.

Abstract: Methods and apparatuses for group scheduling for physical downlink control channel (PDCCH) overhead reduction. A method of operating a UE includes receiving first configuration information for reception of first PDCCHs. A PDCCH from the first PDCCHs provides a first downlink control information (DCI) format that includes a first number of information bits. The method further includes receiving second configuration information for a location of a second number of information bits, smaller than the first number of information bits, in the first DCI format; receiving at least one of the first PDCCHs; and determining, from the second number of information bits, values of one or more fields associated with reception of a first physical downlink shared channel (PDSCH) or with transmission of a first physical uplink shared channel (PUSCH).

Abstract: Resources are configured, by frame/subframe/slot/symbol, for uplink communication components, downlink communication components, radar sensing components, or flexible components. Flexible components are configured by symbol for uplink or downlink communications, radar sensing, or flexible usage. Full, partial or no overlap between resources for uplink, downlink or sidelink communication and resources for radar sensing may be configured. Frequency configuration for radar sensing may be in absolute units or grid units, and waveforms other than OFDM may be used for radar sensing. Configuration may be initiated by a base station in response to explicit or implicit request by a UE for sensing resources. A UE may sense resources within a configured resource pool for availability before using the resources for radar sensing.
