Abstract: This disclosure provides systems, methods, and apparatuses that enable abase station (BS) to transmit downlink control information (DCI) without downlink data to indicate a transmission configuration indicator (TCI). In one aspect, a user equipment (UE) may transmit a capability indication associated with whether the UE can receive DCI with a TCI and without a data assignment. The UE may receive DCI with one or more configured fields and without downlink data and may interpret the DCI, based on the one or more configured fields, to identify a TCI. The TCI may be a Type 1 beam indication or another type of beam indication. The DCI may C be a DCI format 1_1 or 1_2 or another DCI format, such as DCI format 1_0 or a DCI scheduling an uplink configuration, among other CN examples, and may indicate another configuration with the TCI.

Abstract: Schemes and mechanisms for beam prediction using per-beam error statistics are provided. A UE may receive, from a network, a beam prediction configuration. The beam prediction configuration may be for a machine learning model or algorithm. The UE may receive error statistics for each of a plurality of beam directions. Responsive to the UE identifying a first beam direction of the plurality of beam directions using the beam prediction configuration and based on the error statistics, the UE transmits an uplink (UL) communication to the network in the first beam direction. Responsive to the UE identifying a second beam direction of the plurality of beam directions using the beam prediction configuration and based on the error statistics, the UE transmits the UL communication to the network in a third beam direction different from the second beam direction.

Abstract: Aspect are direction to techniques for predicting future beams (e.g., transmit beams and/or receive beams) for communications between a network node and a user equipment (UE). In some examples, the UE may output, for transmission to a network node, beam information of a receive beam. The UE may obtain, via a beam pair comprising the receive beam and a transmit beam, signaling from the network node. In some examples, the UE may output, for transmission to the network node, a measurement of the signaling from a perspective of the receive beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting user equipment (UE) may receive, from a network node, a sidelink grant that indicates a sidelink resource and indicates a set of sidelink beams associated with a sidelink communication using the sidelink resource. The UE may select, based at least in part on the set of sidelink beams indicated in the sidelink grant, a sidelink beam for the sidelink communication. The UE may transmit, via the selected sidelink beam, the sidelink communication to one or more receiving UEs using the sidelink resource indicated in the sidelink grant. Numerous other aspects are provided.

Abstract: Method and apparatus for a UE to request a TCI state switch for blockage conditions. The apparatus predicts a blockage condition to a first beam communicating with a network node. The apparatus transmits, to the network node, a beam switch indication indicating a scheduled change in a TCI state mapped from the first beam to a second beam in response to the predicted blockage condition. The apparatus may schedule a beam change to the second beam based on the predicted blockage condition. The apparatus may correlate a beam change to the second beam at the UE with a corresponding beam change at the network node.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.
