  • Publication number: 20250184053
    Abstract: Systems and methods for coverage enhancements for sidelink (SL) synchronization signal block (SSB) (S-SSB) between a transmit (Tx) user equipment (UE) and a receive (Rx) UE are disclosed herein. S-SSB frequency domain enhancement may use frequency hopping for S-SSB and/or S-SSB that use an increased number of physical radio bearers (PRBs). S-SSB time domain enhancements may modify an S-SSB periodicity, a number of S-SSB per period, use a clear channel assessment (CCA) (or listen before talk (LBT)) procedure, and/or transmit only some of a configured set of S-SSBs for an S-SSB periodicity. Multi-beam S-SSB enhancement may index S-SSBs of a configured set and send those S-SSBs using beams corresponding to the indexes. S-SSB enhancement using frequency domain masking and/or time domain masking may apply different masks to one or more S-SSBs.

  • Publication number: 20250183965
    Abstract: The present application relates to a reduced complexity UE. In an example, the UE includes multiple receive ports to support downlink multiple input multiple output (MIMO) operations. This set can be six or more to support six or more layers for the downlink MIMO operations. A first set of the receive ports are logically grouped in a first group, and a second set of the receive ports are logically grouped in a second group. A channel state information (CSI) sent by the UE to a base station can indicate the mapping of the layers (or the receive ports) to codewords that the base station is to send to the UE. Additionally, or alternatively, an SRS transmission by the UE is associated with a particular group of the receive ports.

The Tx UE may send a combined physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) having one or more channel state information reference signals (CSI-RSs) on corresponding beams to the Rx UE. The Rx UE may perform beam measurement on the CSI-RSs and send a beam report to the Tx UE that is based on such measurement. Systems and methods for triggering SL beam measurement between the Tx UE and the Rx UE, for performing various procedures for SL beam maintenance between the Tx UE and the Rx UE, and for sending beam reports between the Tx UE and the Rx UE are described.

  • Patent number: 12323836
    Abstract: Systems and methods are provided for determining which part or operation of one or more Secondary Cell (SCell) activation process (es) to defer or restart when an attempt to simultaneously perform multiple operations of the one or more SCell activation processes would cause interference. For example, radio frequency (RF) tuning and/or automatic gain control (AGC) settling for an SCell activation may be deferred until after a Hybrid Automatic Repeat Request (HARQ) for the SCell activation is sent by a UE to the SCell. In another example, RF tuning and/or AGC settling corresponding to the activation of a first SCell may be deferred until after RF tuning and/or AGC settling corresponding to the activation of a second SCell is complete.

  • Patent number: 12323834
    Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

  • Publication number: 20250176065
    Abstract: Apparatuses, systems, and methods for inactive mode DRX cycle and/or measurement cycle determination, e.g., such as for radio resource management (RRM) in inactive mode, e.g., in 5G NR systems and beyond, including systems, methods, and mechanisms for determining a DRX cycle for cell detection and measurement. An inactive mode DRX cycle periodicity may be determined by scaling a periodicity of an idle mode DRX cycle, an inactive mode eDRX cycle, an idle mode eDRX cycle, and/or by a paging occasion cycle. The scale factor may be predefined, specified by a standard, and/or configured via higher layer signaling. Additionally, whether an inactive mode DRX cycle is determined by scaling a periodicity of an idle mode DRX cycle, a paging occasion cycle, an inactive mode eDRX cycle, or an idle mode eDRX cycle may depend on one or more conditions associated with a UE.

  • Patent number: 12317142
    Abstract: Some embodiments include an apparatus, method, and computer program product for using low layer protocols for inter-cell mobility management in a 5G wireless communications system. A serving 5G node B (gNB) can configure reports that a user equipment (UE) transmits to the serving gNB to make handover decisions. The serving gNB can configure a group of Transmission Configuration Indication (TCI) states (e.g., a group of beams) that correspond a physical cell, and the report includes layer 3 measurements corresponding to a neighboring or serving cell's TCI state. The report can be conveyed using lower layer protocols. The report can include layer 1 measurements conveyed using a layer 1 protocol and the serving gNB can perform filtering to generate corresponding layer 3 measurement results. Based on the reports, the serving gNB can perform a handover and synchronization using lower layer protocols, from one TCI state to another.
