  • Publication number: 20250063589
    Abstract: Scheduling with split symbols for beam management is described. An apparatus is configured to receive, from a network node, DL signaling including a symbol in a first slot, and to measure a first measurement of a first beam during a first time portion, and a second measurement of a second beam during a second different time portion, of the symbol. The apparatus is configured to communicate, with the network node, using the first or second beam based on at least one of the first measurement or the second measurement. Another apparatus is configured to provide, for a UE, DL signaling including a symbol in a first slot, and to communicate, with the UE, using the first or second beam based on a first and/or second measurement. The first and second measurements are of first and second beams during a first and second different time portions of the symbol, respectively.

  • Publication number: 20250030467
    Abstract: Aspects of the disclosure are directed to generation of N-port dynamic beams. For example, a user equipment (UE) may be using a 2-port predefined receive beam for communication with a wireless node. The UE may estimate a channel using the predefined receive beam to measure a rank2 reference signal received from the wireless node. The UE may generate a dynamic beam weight to maximize a communication parameter based on the estimated channel. The UE may then apply the dynamic beam weight to an antenna array.

  • Publication number: 20240380470
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, for a UE beam refinement procedure, a reference signal via a first network node beam. The UE may receive, based at least in part on the UE beam refinement procedure, an indication of a switch to the first network node beam from a second network node beam. Numerous other aspects are described.

  • Publication number: 20240251397
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during a beam management procedure, multiple sets of channel state information reference signals (CSI-RSs). The UE may receive multiple CSI-RSs, wherein one CSI-RS of the multiple CSI-RSs is associated with one set of CSI-RSs of the multiple sets of CSI-RSs, and wherein a beam associated with the one CSI-RS corresponds to a beam associated with the one set of CSI-RSs. The UE may transmit multiple channel quality indicator (CQI) reports based at least in part on the multiple CSI-RSs, wherein one CQI report of the multiple CQI reports is based at least in part on the one CSI-RS of the multiple CSI-RSs. Numerous other aspects are described.

  • Publication number: 20240146379
    Abstract: Methods and apparatus for beam management where a beam is selected based on an estimated channel correlation matrix. The apparatus determines a channel correlation matrix based on downlink SSB reference signal received at the UE. The apparatus estimates a RSRP of a plurality of beams associated with an uplink channel based on the channel correlation matrix and associated beam weights. The apparatus selects a first beam from the plurality of beams having a highest estimated RSRP for communication with a base station. The apparatus communicates with the base station via the first beam.
