Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.

Abstract: Systems and techniques are provided for wireless communication. A first network entity (e.g., a user equipment (UE)) can receive information indicative of a configuration for multicast discontinuous reception (DRX). The information can be received from a second network entity (e.g., a base station). The first network entity can perform unicast data communication using one or more multicast DRX cycles of a plurality of multicast DRX cycles corresponding to the configuration, wherein the unicast data communication is performed between the first network entity and the second network entity. A second network entity (e.g., a base station) can transmit, to a user equipment (UE), information indicative of a configuration for multicast discontinuous reception (DRX). The second network entity can perform unicast data communication with the UE using one or more multicast DRX cycles of a plurality of multicast DRX cycles corresponding to the configuration.

Abstract: A network node may configure a UE for discontinuous reception (DRX). The network node may transmit, to the UE, a plurality of DRX configurations. Further, the network node may transmit, to the UE, information associated with an active time of a first DRX configuration of the plurality of DRX configurations, with the active time being different from an inactive time of the first DRX configuration. Further, the network node may transmit, to the UE, data based on the active time of the first DRX configuration. The UE may receive the plurality of DRX configurations. Further, the UE may receive the information associated with the active time of the first DRX configuration. The UE may monitor for data based on the active time of the first DRX configuration.

Abstract: A method for wireless communication at a first user equipment (UE) and related apparatus are provided. In the method, the first UE communicates with one or more UEs over SL (SL). The first UE further transmits or receives configuration information for SL communication with the one or more UEs or uplink communication with a network entity. The method improves the reliability of wireless communication, particularly in XR-related applications, and facilitates the power transfers of energy harvesting UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain, at an access stratum (AS) layer, an indication of an inter-satellite link (ISL) activation that is to take place at an activation time. The wireless communication device may receive communications. The wireless communication device may buffer the communications in a buffer at the AS layer. The wireless communication device may release the communications from the buffer to an upper protocol layer at a rate of release that is to change between a transition start time and the activation time. Numerous other aspects are described.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first user equipment (UE) includes receiving, from a network unit operating in full duplex mode, a configuration indicating scheduled uplink communication resources and interference level measurement resources, measuring, based on the interference level measurement resources, an interference level associated with a second UE, and performing, for a scheduled uplink communication, at least one of transmitting, based on the measured interference level associated with the second UE and based on the scheduled uplink communication resources, the scheduled uplink communication or refraining, based on the measured interference level associated with the second UE, from transmitting the scheduled uplink communication.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Method and apparatus for dynamic PDCCH skipping for XR. The apparatus receives a PDCCH skipping configuration. The apparatus receives an indication to perform a PDCCH skipping procedure based on the PDCCH skipping configuration. The apparatus determines to monitor a DCI during the PDCCH skipping procedure based on the PDCCH skipping configuration. The apparatus may transmit a UE capability report indicating that the UE supports a dynamic behavior of monitoring for the DCI that schedules a retransmission during a PDCCH skipping period. The apparatus may monitor a non-scheduling DCI based PDCCH monitoring adaptation indication. The apparatus may perform a dynamic behavior of monitoring for the DCI that schedules a retransmission during a PDCCH skipping period.

Abstract: Certain aspects of the present disclosure provide techniques for random access. A method for wireless communications by a user equipment (UE) includes determining a first timing advance (TA) for transmitting a random access channel (RACH) preamble. The method includes determining a second TA, different than the first TA, for transmitting the RACH preamble. The method includes transmitting the RACH preamble using the second TA. The method includes receiving a random access response (RAR) message including a timing advance command (TAC) and determining whether the RAR is intended for the UE based on the TAC, the first TA, and the second TA. The method includes transmitting a physical uplink shared channel (PUSCH) transmission based on a determination that the RAR is intended for the UE.
