  • Patent number: 12289269
    Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.

  • Patent number: 12289264
    Abstract: Aspects are provided allowing a UE to transmit repetitions of an ULT, PEI-R, or other uplink reference signal for on-demand SSB, RMSI, or paging transmissions. A base station initially transmits an indication of a configured uplink repetition mode, which may comprise a first, second, or third mode in which a one-to-one, one-to-many, or many-to-many mapping exists between downlink reference signals and uplink occasions, respectively. Afterwards, the UE receives downlink reference signals via different transmission beams of the base station. In response to the downlink reference signals, the UE transmits an uplink reference signal repetition in one or more uplink occasions associated with one or more of the downlink reference signals according to the configured uplink repetition mode. In response to the uplink reference signal repetition, the base station may transmit a SSB, RMSI, or paging message. Thus, a balance between network energy savings and uplink signal reliability may be achieved.

  • Patent number: 12289774
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving, from a base station, one or more random access channel (RACH) configurations. The RACH configurations may allocate resources for a contention-based RACH procedure for accessing a wireless network. Based on the RACH configurations, the UE may determine a set of random access occasions for an association period. From the set of random access occasions, the UE may map one or more indices of a plurality of synchronization signal blocks to one or more random access occasions. Using the one or more random access occasions, the UE may transmit a random access sequence, including one or more repetitions of the random access sequence to the base station to access the wireless network.

  • Patent number: 12289777
    Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

  • Patent number: 12279235
    Abstract: Methods, systems, and devices for wireless communication are described. In some cases, a sidelink user equipment (UE) operating in a power saving mode may identify a resource reservation configuration for communicating within a resource pool allocated for sidelink communications. The UE may operate in a first power state of the power saving mode during a sensing window. The sensing window may correspond to a resource selection window of the resource pool. The UE may transition, after the sensing window, from the first power state to a second power state that may consume more power than the first power state. The UE may identify a subset of resources of the resource pool in the resource selection window that are available for sidelink transmission by the UE based on transitioning between the first power state and the second power state.

  • Patent number: 12273858
    Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.
