  • Publication number: 20230379977
    Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for retransmitting a random access channel (RACH) message, for example, based on parameters for initial RACH transmission. For example, a user equipment (UE) transmits an initial transmission of an uplink RACH message with repetition. The UE receives a downlink control information (DCI) scheduling a retransmission of the uplink RACH message with repetition. The UE determines parameters for the retransmission of the uplink RACH message with repetition based, at least in part, on parameters for the initial transmission of the uplink RACH message with repetition. The UE retransmits the uplink RACH message to the network entity with repetition in accordance with the determined parameters.

  • Patent number: 11825516
    Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

  • Patent number: 11825410
    Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

  • Publication number: 20230370240
    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support a network indication of full-duplex capabilities. For example, a user equipment (UE) may receive, from a network entity, a capability message indicating that the network entity supports one or more modes of a full-duplex communications scheme. The capability message may be associated with an access procedure between the UE and the network entity and the UE may perform the access procedure with the network entity. The UE may communicate with the network entity based on the access procedure and the network entity supporting the one or more modes associated with the full-duplex communications scheme.

  • Publication number: 20230370951
    Abstract: Methods, systems, and devices for wireless communications are described for cell access techniques in carrier aggregation configurations in which one or more carriers do not provide discovery signals such as synchronization signal block (SSB) transmissions. A UE may be configured with an anchor carrier on which SSBs are transmitted, and one or more non-anchor carriers on which SSBs are not transmitted. A single cell barring indication may be provided for the anchor carrier, in which case the UE may follow cell barring indications for associated non-anchor carriers. In other cases, separate cell barring indications may be provided for one or more anchor carriers and one or more non-anchor carriers.

  • Publication number: 20230370231
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, an indication of a set of resources for transmitting a set of phase-coherent sounding reference signals (SRSs). The UE may receive, from the base station, a control message indicating a cancellation of an allocation of a first portion of the set of resources. The UE may determine a phase coherency configuration associated with a second portion of the set of resources based on receiving the control message indicating the cancellation. The UE may then be configured to transmit one or more SRSs within the second portion of the set of resources in accordance with the determined phase coherency configuration.

  • Publication number: 20230371071
    Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

  • Patent number: 11818683
    Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

  • Publication number: 20230362966
    Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

  • Publication number: 20230362820
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE). In some systems, the UE may implement techniques for power savings by operating according to a narrower BWP in accordance with an energy level at the UE. In some implementations, the UE may reduce the bandwidth size of the active BWP if the UE energy level satisfies a threshold. The UE may transmit signaling to the network indicating that the bandwidth size of the active BWP is reduced. Additionally, or alternatively, the UE may fall back to a default BWP if the UE energy level satisfies a threshold. For example, the UE may fall back to the default BWP prior to expiration of a timer configured to trigger the UE to fall back to the default BWP.
