  • Patent number: 11974256
    Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

  • Patent number: 11968015
    Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.

  • Patent number: 11962399
    Abstract: Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

  • Patent number: 11950284
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

  • Patent number: 11943756
    Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time.

  • Publication number: 20240089766
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.
