Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may monitor for sidelink messages among multiple UEs using transmission-side sensing. The first UE may monitor for sidelink messages over a transmit beam selected for transmitting data from the first UE. The first UE may receive, from a second UE, a sidelink message including an indication of resources reserved for sidelink transmissions to the second UE. Based on the indication, the first UE may select available resources over which to transmit data. The first UE may receive the sidelink message over a sidelink feedback channel.

Abstract: A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: A base station may instruct a UE to use at least one weighting factor associated with a CR for the UE, and the UE may apply the at least one weighting factor to the one or more resources scheduled for the PSSCH transmission to determine the CR. The UE may transmit the PSSCH in the one or more resources of the at least one slot based on the determined CR being less than or equal to a CR threshold value. The at least one weighting factor may be applied to the one or more resources in each of multiple slots scheduled for transmission of a PSSCH.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication, including techniques for sidelink resource allocation and communication. In some aspects, a user equipment (UE) may receive from a base station a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE. The UE may transmit the information to the second UE in the first transmission opportunity. The UE may also retransmit the information to the second UE in at least one of the one or more additional transmission opportunities responsive to the transmission of the information in the first transmission opportunity being unsuccessful. Other aspects and features are also claimed and described.

Abstract: A sidelink user equipment (UE) receives a group wake-up signal (WUS) from a base station and decodes the group WUS based on zone identification (ID) information of the sidelink UE. A base station transmits a wake-up signal to a group of sidelink user equipments (UEs) and transmits zone ID information to the group. A group wake-up signal parameter is a function of the zone ID information. A base station generates a demodulation reference signal (DMRS) sequence, selects a port for a DMRS, and/or scrambles a control channel or a data channel based on a zone ID of a sidelink UE. A sidelink UE compares a zone ID of the sidelink UE with a zone ID of a neighbor UE and initiates a conditional handover to another cell when the zone ID of the sidelink UE differs from the zone ID of the neighbor UE.

Abstract: Systems and method for configuring and providing discontinuous reception (DRX) operations in sidelink (SL) mode 1 and mode 2 are disclosed. A first user equipment (UE) may operate in DRX communications with a second UE over a SL while concurrently maintaining DRX communications with a base station. In some embodiments, DRX operations may include the first UE monitoring for either one or both of transmissions in a downlink from a base station and in the SL from the second UE during an active period of a DRX cycle of the DRX configuration. In embodiments, the UE may extend the active period associated with the DRX cycle when control information from either the base station or the second UE is received. Other aspects and features are also claimed and described.

Abstract: Apparatus, methods, and computer-readable media for facilitating a flush indicator for uplink transmissions and sidelink transmissions are disclosed herein. An example method for wireless communication at a UE includes transmitting a first transmission of one or more code blocks to a first device. Additionally, the example method includes retransmitting, to the first device, at least one code block of the one or more CBs. Further, the example method includes transmitting, to the first device, a flush indicator indicating to avoid combining a prior transmission of the at least one code block with the retransmission of the at least one code block.
