  • Publication number: 20240178889
    Abstract: Techniques, described herein, include solutions for managing uplink control information (UCI) transmission for a channel state information (CSI) report resulting from measurements of CSI measurement resources. In response to the CSI report exceeding allocated uplink resources of a UCI transmission, a compressed CSI report can be generated by performing an uplink control information (UCI) omission to omit parameters of the CSI report based on components comprising frequency domain (FD) components and time domain (TD) components of the MIMO codebook configuration. The UCI transmission can be generated with the compressed CSI report.

  • Publication number: 20240179734
    Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

  • Publication number: 20240178962
    Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

  • 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: 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.

  • 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: 20240172149
    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.

  • 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).

  • 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.
