Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting simultaneous multi-beams on the same wireless resource. One example method includes determining a set of transmission (TX) beams for simultaneous transmissions to or from a user equipment (UE), signaling to the UE an indication of the TX beams, and transmitting simultaneously via the TX beams.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to techniques for multiple transmission and reception point (TRP) transmission of channel state information reference signal (CSI-RS) resources. In one aspect, a user equipment (UE) can receive a CSI-RS resource including a first CSI-RS port on a first beam from a first cell of a network entity, the CSI-RS resource including a second CSI-RS port of the second cell on a second beam from a second cell of the network entity. In another aspect, a network entity can transmit, on a first beam from a first cell to a UE, a CSI-RS resource including a first CSI-RS port of the first cell, and transmit, on a second beam from a second cell to the UE, the CSI-RS resource including a second CSI-RS port of the second cell.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for applying a common beam for multiple signals to a default beam for a physical downlink shared channel (PDSCH). An example method generally includes receiving, from a network entity, configuration information, identifying a common beam for wireless communications between the UE and the network entity based on the received configuration information, identifying a default beam based, at least in part, on the common beam and one or more rules, and receiving a physical downlink shared channel (PDSCH) by using the identified default beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive synchronization signal block (SSB) information that indicates, for each respective SSB of one or more SSBs, a quantity of how many beams are associated with the respective SSB. The UE may monitor SSBs, determine one or more beams that provide an SSB based at least in part on the SSB information, and direct one or more reception beams toward the one or more beams. Numerous other aspects are provided.

Abstract: Some aspects described herein relate to configuring user equipment (UE) for performing sidelink (SL) random access (RA) procedures, which may include assistance from a base station or other network component. One or more parameters for performing a random access procedure with a second UE over a sidelink can be received from a base station. A first random access message can be transmitted to the second UE as part of the random access procedure over the sidelink. A second random access message can be received, from the second UE, in response to transmitting the first random access message, and as part of the random access procedure over the sidelink, where at least one of transmitting the first random access message or receiving the second random access message are based on the one or more parameters.

Abstract: A configuration to configure a UE to activate a subset of configured UL-TCI states. The apparatus receives a configuration of UL-TCI states and an activation of a subset of configured UL-TCI states. The apparatus receives DCI in a PDCCH scheduling an UL transmission with one or more TCI states of activated TCI states. The apparatus transmits the UL transmission based on the one or more TCI states.

Abstract: Techniques for signaling uplink transmission configuration indicator (TCI) states are disclosed. In an example, a base station may determine one or more capabilities of a user equipment (UE). The base station may also determine one or more uplink TCI states for the UE to use based on the one or more capabilities. The base station may also transmit, to the UE, signaling of the one or more uplink TCI states.

Abstract: A UE configured to report resources, such as beams, to a base station may be unaware of the context or purpose for which the UE is reporting such resources. As different resources may provide different performance and/or quality when used in different contexts, the resources reported by the UE may provide lower quality and/or performance in one context relative to some other unreported resources. In order to improve resource reporting by the UE, the UE may be informed of an operational mode and/or a criteria based upon which the UE may select resources to report. The UE may report such selected resources to the base station in a group-based beam report. The base station may then configure communication with the UE based on the reported resources.

An example method generally includes receiving uplink transmission configuration indicator (TCI) indicating one or more quasi co-location (QCL) types, from a plurality of uplink QCL types, for one or more source reference signals (RSs); and sending an uplink transmission in accordance with the uplink TCI.
