  • Patent number: 11997509
    Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

  • Publication number: 20240171356
    Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to process or generate an acknowledgement (ACK) or a non-acknowledgement (NACK) of a beam report to indicate an autonomous transmission configuration indicator (TCI) state update, which can be a TCI update without a corresponding TCI indication/trigger. The UE can determine the ACK/NACK in response to providing the beam report in the autonomous TCI state update. The UE can then activate a TCI state of the autonomous TCI state update in response to identifying the ACK or re-transmit the beam report for autonomous TCI state update when a NACK is recognized.

  • Publication number: 20240172018
    Abstract: Some aspects include an apparatus, method, and computer program product for radio resource management measurement prioritization for reduced capacity (RedCap) user equipment (UE). A RedCap UE may be use Half-Duplex Frequency Division Duplex (HD-FDD) for wireless communications. When performing communications with a network, the RedCap UE may make several measurements, including Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ) measurements. To obtain these measurements, the RedCap UE may measure Synchronization Signal Block (SSB), Received Signal Strength Indicator (RSSI), and/or Channel State Information Reference Signal (CSI-RS) symbols. Difficulties may arise when a RedCap UE's serving cell signal timing is not synchronized with a neighboring cell. The RedCap UE may be configured to prioritize measurements over uplink transmissions.

  • Publication number: 20240172148
    Abstract: Techniques described herein may enable base stations and user equipment (UEs) to implement initial access related signaling that may vary the number of synchronization signal blocks (SSBs) transmitted by a base station to better ensure that control frame transmissions (e.g., 120 kilohertz (kHz) subcarrier spacing (SCS) transmissions) are not overly encumbered by SSBs. A base station may indicate whether a discovery burst transmission window (DBTW) is enabled or disabled, whether listen-before-talk (LBT) is enabled or disabled, and whether transmissions correspond to a licensed band, unlicensed band, or combination thereof. The base station may also indicate a number of candidate SSBs per DBTW and/or which SSBs/SSB groups are active (e.g., actually transmitted) per discovery burst (DB).

  • Publication number: 20240172049
    Abstract: A method is to provide traffic related information in lower layers for an XR system and associated apparatuses. In one aspect, a user equipment (UE) is configured to receive traffic related information from a peer UE or an application server. The UE then transmits the traffic related information to a base station (BS) using a radio resource control (RRC) message such as UEAssistanceInformation as provided by 3GPP technical specifications, a medium access control (MAC) control element (CE), or a physical uplink control channel (PUCCH). The transmission of the traffic related information from the UE enhances the wireless communication service for the XR system.

    Abstract: A base station and user equipment (UE) may determine, based on a synchronization signal block (SSB) burst and an offset, an index slot, of a system frame number (SFN), corresponding to a Type0-PDCCH common search space (CSS). The base station may transmit, and the UE may receive, a PDCCH signal that includes the Type0-PDCCH CSS, such that the UE may monitor the Type0-PDCCH CSS from the base station. The offset (Ou) may be hardcoded as one of values 0, 2.5, 5, or 7.5, and one offset value may be used for one, more than one, or all SCS numerologies. The offset may be modified by a delta (?) value, a scaling factor, and/or a combination thereof.

    Abstract: Systems and methods for implementing various metrics for in integrated IAB networks are disclosed. A child IAB node may determine metrics regarding one or more of its data flows and report these metrics to an upstream IAB node (that is a parent node and/or an IAB donor). The upstream node may determine a data flow prioritization configuration using these metrics that it either uses itself or sends back to the child IAB node or another IAB node of the IAB network for use there. Metrics discussed include a number of hops metric, an aggregate throughput per BH RLC channel ID (or per routing ID) metric, a fairness index per BH RLC channel ID (or per routing ID) metric, a packet drop metric, and a per-hop latency for aggregated traffic per BH RLC channel ID (or per routing ID) per IAB node metric.

  • Patent number: 11990958
    Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.

  • Patent number: 11991716
    Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.
