A wireless transmit/receive unit (WTRU) may receive configuration information indicating a first and a second cell group, and indicating discontinuous reception (DRX) information for them; and may receive a command associated with DRX. The WTRU may perform, based on the command, DRX for cells of the first and second cell groups. A first active time for the first cell group may differ from a second active time for the second cell group. Cells within the first cell group may be active during the first active time; cells within the second cell group may be active during the second. The WTRU may receive a first command to deactivate a first cell of the first cell group, and deactivate the cell based on the first command. The WTRU may receive a first command to reactivate the deactivated first cell, and reactivate the deactivated first cell based on the first command to reactivate.

Method and Device in nodes for wireless communication. A first node receives a first configuration information block, a first signaling and a first reference signal resource. The first configuration information block comprises configuration information of the first reference signal resource; the first signaling indicates a first transmission configuration state; the first configuration information block is used to determine a first transmission configuration state set; the first signaling is used to determine a first time; a second transmission configuration state is used to determine a spatial relation of the first reference signal resource before the first time; a spatial relation of the first reference signal resource is related to whether the first transmission configuration state belongs to the first transmission configuration state set after the first time. The above method ensures that when the beam is dynamically updated, a TCI state of a reference signal constantly matches its configuration information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first common frequency resource (CFR) within a bandwidth part (BWP) and a second CFR within the BWP. Accordingly, the UE may receive, using a first numerology, a non-group-common communication at least partially in the BWP. The UE may also receive, using the first numerology, a group-common communication at least partially in the first CFR, and receive, using a second numerology, a group-common communication at least partially in the second CFR. As an alternative, the UE may receive an indication of a CFR within a BWP. Accordingly, the UE may receive, using a first numerology, a non-group-common communication in the BWP and a first group-common communication in the CFR, and receive, using a second numerology, a second group-common communication in the CFR. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may decode a first signal received over a broadcast channel during a first synchronization signal block (SSB) occasion to identify a first payload, and determine one or more expected changes between the first payload and a second payload of a second signal expected to be received over the broadcast channel during a second SSB occasion. The UE may update the first payload with the one or more expected changes to determine an updated first payload, and encode the updated first payload as an updated first signal. The UE may receive the second signal over the broadcast channel during the second SSB occasion, and apply the second signal and the updated first signal to a tracking procedure for the UE.

Disclosed are a method and apparatus for determining an occasion of an HARQ-ACK feedback. The method includes: in response to one DCI scheduling PDSCHs of more than one cell, taking a timeslot in which an end occasion of a PDSCH of one of the scheduled cells is located as a reference timeslot, calculating a timeslot in which an occasion of an HARQ-ACK feedback is located according to the following equation: the timeslot in which the occasion of the HARQ-ACK feedback is located=n+k, where n represents the reference timeslot, and k represents a timeslot offset, indicated in the DCI, between the timeslot in which the occasion of the HARQ-ACK feedback is located and the reference timeslot.

A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

The present disclosure relates to data sending methods, terminal devices, access network devices, and systems. One example method includes receiving, by a first terminal device, first resource configuration information from an access network device, where the first resource configuration information indicates a time-frequency resource for sending first data and at least one of frequency domain configuration information or time domain configuration information of the time-frequency resource, sending, by the first terminal device, first control information to a second terminal device, where the first control information indicates the time-frequency resource and at least one of the frequency domain configuration information or the time domain configuration information of the time-frequency resource, and sending, by the first terminal device, the first data to the second terminal device on the time-frequency resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more slots in which an aperiodic channel state information (A-CSI) report communication on a multi-slot physical uplink shared channel (PUSCH) overlaps with a second communication on a physical uplink control channel (PUCCH). The UE may select for a slot of the one or more slots, an uplink communication from the A-CSI report communication or the second communication based at least in part on a first priority assigned to the A-CSI report communication and a second priority assigned to the second communication. The UE may determine whether to transmit the uplink communication on the multi-slot PUSCH or the PUCCH in the slot. The UE may transmit the uplink communication in the slot. Numerous other aspects are provided.

A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator (103) generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator (104) generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator (103). The wireless transmitter/receiver (106) transmits the Trigger frame, generated by the Trigger frame generator (104), to a terminal (200).

A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability performs at least a part of initial access based on an initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE switches, after the initial access, to an active downlink BWP and an active uplink BWP that are dedicated for the UEs having the first capability to perform random access, paging, system acquisition, measurement and data communication procedures.
