Abstract: The aspects described herein may enable a base station to repeat a downlink control channel based on one or more indications received from a user equipment (UE). This may allow the base station to efficiently use network resources to enhance coverage of downlink control channels for different steps of a network access procedure as needed by a UE. For example, a UE may determine to activate or deactivate repetition of a downlink control channel associated with a network access procedure. The UE may transmit an indication configured to activate or deactivate repetition of the downlink control channel.

Abstract: A target user equipment (UE) may receive, from each relay UE of a set of relay UEs, a synchronization signal block (SSB) through each transmit beam of a set of transmit beams from the UE through each receive beam of a set of receive beams at the target UE. The relay UE may transmit the paging message through each transmit beam of the set of transmit beams. The target UE may determine a beam pair based on the received SSB, and receive the paging messaged using the beam pair. The target UE may also receive, from a relay UE, a paging message through one or more sidelink channels from each transmit beam of a set of transmit beams of the relay UE through each receive beam of a set of receive beams at the target UE and decode the received paging message.

Abstract: This disclosure provides systems, methods and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a broadcast sidelink communication that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the broadcast sidelink communication to the second UE.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes monitoring for a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the plurality of monitoring occasions are monitored using different beams; and decoding the PDCCHs after the monitoring.

Abstract: Various aspects pertain to a method for a UE to unilaterally initiate a request to a serving base station to change or enhance beam coverage at the UE. The UE may measure one or more characteristics of a directional beam transmitted by the base station and determines whether channel reliability for the beam should be improved. If channel reliability is below a threshold, then the UE may transmit a request to the base station seeking to adjust coverage of the beam (such as coverage enhancements). Such request may seek to adjust one or more transmit or receive parameters associated with the beam or channels transmitted therein. The UE may switch to using a pre-defined set of coverage enhancement parameters or procedures either automatically after transmitting the request or upon receipt of a grant by the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a configuration for buffer status reporting associated with a sidelink between the first UE and a second UE and a link between the first UE and a base station; generate a buffer status report (BSR) based at least in part on the configuration, wherein the BSR includes buffer reporting information for one or more logical channels on the sidelink between the first UE and the second UE, and buffer reporting information for one or more logical channels on the link between the first UE and the base station; and provide the BSR to the base station. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating a multiple bit new data indicator are disclosed herein. An example method for wireless communication at a first device includes transmitting a first state of a multiple bit new data indicator (NDI) for a first packet. The example multiple bit NDI indicates more than two different states for indicating a new packet. The example method also includes transmitting the first packet. Additionally, the example method includes transmitting a second state of the multiple bit NDI for a second packet, and the second state being different than the first state. Further, the example method includes transmitting the second packet.

Abstract: Apparatus, methods, and computer-readable media for facilitating a HARQ flush indicator for transmissions are disclosed herein. An example method for wireless communication at a first sidelink device includes transmitting a sidelink transmission of one or more CBs using code block groups, each code block group including one or more CBs of the sidelink transmission. The example method also includes receiving negative feedback for at least one CB of the sidelink transmission. Additionally, the example method includes retransmitting the at least one CB. The example method also includes transmitting an FI indicating to avoid combining a prior sidelink transmission of the at least one CB with a retransmission of the at least one CB.
