Abstract: This disclosure provides systems, methods and apparatuses for a selection of one or more transmission and reception points (TRPs) within a multi-TRP system. In one aspect, a user equipment (UE) may transmit an indication of the selected TRPs and an indication of one or more beams that the selected TRPs may use to communicate with the UE based on a mismatch between a default operating frequency (DOF) of each TRP within the multi-TRP system and a DOF of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the TRPs within the multi-TRP system and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select to communicate with TRPs and select one or more ports that the selected TRPs may use to communicate with the UE based on the comparison.

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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

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: This disclosure provides systems, methods, and devices for wireless communication that support power headroom differential reporting for reference resource signals transmitted at different transmission power than other uplink transmissions. In a first aspect, a method of wireless communication includes determining a power headroom value, by a user equipment (UE), using a maximum configured transmission power and a transmission power configured for an uplink transmission at a configured modulation and coding scheme (MCS). The UE determines a reference resource signal power headroom value using the maximum configured transmission power and a reference resource signal transmission power configured for a reference resource signal transmission, calculates a reference resource power headroom differential between the power headroom value and the reference resource signal power headroom value, and transmits a report including the uplink transmission power headroom value and the reference resource power headroom differential. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods and apparatus, including computer storage media for communication between a base station with two transmit receive point (TRPs) and a UE based on a single DCI. The UE receives a single downlink control information (DCI) for the UE that is configured with a first unified transmission configuration indication (TCI) state for a first TRP and second unified TCI state for a second TRP. The DCI includes at least a first TCI field. The UE updates a configuration of at least one of the first unified TCI state to a first updated unified TCI state or the second unified TCI state to a second updated unified TCI state based on the at least one TCI field. The UE communicates with at least one of the first TRP or the second TRP based on the first updated unified TCI state or the second updated unified TCI state.

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.
