  • Patent number: 11997549
    Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

  • Patent number: 11997298
    Abstract: Video decoding systems and techniques are described. A decoder reads first video data from a first block of a video frame. The decoder retrieves neighboring video data from a line buffer. The neighboring video data is from a neighboring block that neighbors the first block in the video frame. The decoder processes the first video data and the retrieved neighboring video data using a constrained directional enhancement filter (CDEF) to generate filtered first video data. The decoder upscales the filtered first video data using an upscaler to generate upscaled filtered first video data. The decoder upscales the retrieved neighboring video data using the upscaler to generate upscaled neighboring video data, for instance after generating the filtered first video data. The decoder processes the upscaled filtered first video data and the upscaled neighboring video data using a loop restoration (LR) filter to generate output video data.

  • Patent number: 11997497
    Abstract: Satellite access to a PLMN with a Fifth Generation (5G) core network (5GCN) is supported by a serving satellite NodeB (gNB). The gNB determines or verifies the country in which a user equipment (UE) is located to ensure that the UE is located in the same country as the PLMN. The gNB may determine the country of the UE based on UE measurements from broadcast satellite signals and a positioning ID (PID) broadcast for each radio cell. The PID frequently changes to prevent spoofing. The gNB may use multiple UE measurements from a moving radio cell over a period of time to generate a more accurate location for the UE. The gNB may indicate to a 5GCN whether the country of the UE has been verified. The 5GCN will determine the location and country of the UE if the gNB indicates that the country is not fully verified.

  • Patent number: 11996918
    Abstract: This disclosure provides systems, methods and apparatuses for a selection of one or more transmission and reception points (TRPs) within a multi-TRP system. In one aspect, a user equipment (UE) may transmit an indication of the selected TRPs and an indication of one or more beams that the selected TRPs may use to communicate with the UE based on a mismatch between a default operating frequency (DOF) of each TRP within the multi-TRP system and a DOF of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the TRPs within the multi-TRP system and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select to communicate with TRPs and select one or more ports that the selected TRPs may use to communicate with the UE based on the comparison.

  • Patent number: 11997629
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

  • Patent number: 11997656
    Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

  • Patent number: 11997687
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more downlink grants while operating in accordance with a first receive state during a threshold number of transmission time intervals (TTIs). The UE may determine a weighting factor for each TTI within the threshold number of TTIs, where the determined weighting factors are based on a spectral efficiency (SPEF) of channel communications between the UE and a base station. The UE may sum a subset of the weighting factors to determine a transition determination value, and may transition from the first receive state to a second receive state based on evaluation of the transition determination value.

  • Patent number: 11997667
    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support control of feedback reporting associated with broadcast or multicast transmissions based on indications of non-numerical K1 (NNK1) in associated transmission grants. In aspects, a base station transmits multicast transmission grants that include NNK1s to a set of UEs. The UEs in the set of UEs generate feedback codebooks, for the multicast transmissions, and holds transmission of the codebooks, based on the NNK1 received in the transmission grants until a report triggering event occurs. In aspects, the report triggering event includes receiving a subsequent multicast transmission grant with a valid K1, receiving a subsequent unicast transmission grant with valid K1, or receiving a UE-specific multicast retransmission grant. In aspects, the UEs use the valid K1 in the triggering event to determine a feedback resource to transmit the held feedback codebooks. Other aspects and features are also claimed and described.
