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: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.

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: In an aspect, a UE determines a mapping a mapping between (i) one or more measurements of one or more reference signals based on one or more transmit codebooks and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals. The UE transmits an indication of the mapping to a position estimation entity. The position estimation entity determines a positioning estimate of the UE based at least in part upon the one or more AoDs.

Abstract: A user equipment (UE) may receive, from a base station, a sounding reference signal (SRS) configuration indicating at least two resource allocations for each SRS resource of an SRS resource set, and each of the at least two resource allocations may include a time resource allocation and a frequency resource allocation. The UE may further transmit, to the base station, an SRS on a respective SRS resource of the SRS resource set based on one of the at least two resource allocations for the respective SRS resource. The base station may transmit, to the UE, the SRS configuration indicating at least two resource allocations for each SRS resource of an SRS resource set, and receive, from the UE, the SRS on a respective SRS resource of the SRS resource set based on the one of the at least two resource allocations for the respective SRS resource.
