  • Publication number: 20250119197
    Abstract: A base station includes a transceiver and a processor. The processor is configured to transmit a first synchronization signal block (SSB) burst including a first set of SSBs. The first set of SSBs is transmitted via the transceiver on a first set of beams having a first beam pattern. The processor is also configured to signal, via the transceiver, a change in beam pattern for transmitted SSBs. The change in beam pattern is signaled before or during transmission of a second SSB burst. The processor is further configured to transmit the second SSB burst. The second SSB burst includes a second set of SSBs transmitted via the transceiver on a second set of beams having a second beam pattern. The second set of beams has a different number of beams than the first set of beams, and the second set of SSBs has a different number of SSBs than the first set of SSBs.

  • Patent number: 12273741
    Abstract: Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch is due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.

  • Patent number: 12267131
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing capability signaling design for 3rd Generation Partnership Project (3GPP) release 15 (Rel-15) and/or release 16 (Rel-16) multi-input multi-output (MIMO) enhancement. For example, systems and methods are provided implementing designs for New Radio (NR) MIMO channel state information (CSI) for a small bandwidth part (BWP) and/or a small number of subbands. For example, some aspects relate to a user equipment (UE) including a transceiver configured to communicate with a base station and a processor communicatively coupled to the transceiver. The processor receives, from the base station, a CSI reporting configuration message. The processor determines, using the CSI reporting configuration message, that a number of physical resource blocks (PRBs) of a BWP associated with the CSI reporting configuration message is less than a threshold number. The processor also generates and transmits a CSI report for the BWP.

  • Patent number: 12267882
    Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.
