  • Publication number: 20250056602
    Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.

  • Publication number: 20250056557
    Abstract: Methods, systems, and devices for wireless communication are described that provide for aligning a starting time of a cell-based discontinuous transmission (DTX) and/or discontinuous reception (DRX) mode between a network entity and one or more user equipment (UE) within the serving cell associated with the network entity. The aligning may be accomplished via coordinated signaling. For example, the network may configure a periodic interval for transmitting information related to a discontinuous operation mode in group common downlink control information (GC DCI) messages. In some additional examples, the periodic interval may allow for beam sweeping of the GC DCI messages and efficient cell-based activation or deactivation of the discontinuous operation mode.

  • Publication number: 20250056580
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate generally to control channel monitoring adaptation for a multicast broadcast service (MBS). Some aspects more specifically relate to defining an applicability of control channel monitoring adaptation for a search space that is configured for monitoring a control channel associated with the MBS. In some aspects, a user equipment (UE) may receive a configuration for a search space for monitoring a control channel for downlink control information (DCI) that is associated with the MBS. Additionally, one or more control channel monitoring adaptation parameters may be applicable to the search space. In some aspects, an application of control channel monitoring adaptation when monitoring the control channel (via the search space) for DCI that is associated with the MBS may be associated with a radio resource control state of the UE.

  • Patent number: 12225482
    Abstract: Aspects are provided which allow AGC symbols to be applied for identifying or indicating target Rx UEs of sidelink communications from Tx UEs. A Tx UE transmits an AGC signal to a Rx UE in a RB associated with the Rx UE. The Rx UE receives the AGC signal from the Tx UE. The Tx UE transmits sidelink data to the Rx UE after the AGC signal. The Rx UE decodes sidelink data from the Tx UE in response to the AGC signal being received in a RB associated with the Rx UE. The Rx UE refrains from decoding the sidelink data from the Tx UE in response to the AGC signal being received in a different RB than the RB associated with the Rx UE. In this way, Rx UEs may save monitoring and processing power and time in receiving and decoding sidelink communications.

  • Publication number: 20250048402
    Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit reference signals bursts during an initial beam pairing (IBP) resource. In some examples, each reference signal burst may include an occasion for transmitting a reference signal of a set of reference signals. A second UE may measure the reference signals during the IBP resource and may determine a beam for sidelink communications with the first UE based on measuring the set of reference signals. The second UE may transmit a response message during a response occasion of the IBP resource, where each response occasion within the IBP resource corresponds to a respective reference signal of the set of reference signals. As such, the second UE may transmit a response message during a response occasion that corresponds to the reference signal associated with the selected beam, thereby indicating the selected beam to the first UE.

  • Publication number: 20250039909
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sidelink communications and PSFCH padding. In some aspects, a channel occupancy time (COT) initiating UE may obtain physical sidelink feedback channel (PSFCH) information indicating that a PSFCH transmission is to occupy a common interlace and one or more physical resource blocks. The COT initiating UE may communicate a padding signal within a PSFCH gap of the common interlace in accordance with identifying that the COT initiating UE and the responding UE are not to transmit hybrid automatic repeat request (HARQ) feedback within the PSFCH gap of the common interlace. In some other aspects, the PSFCH information may indicate that the PSFCH transmission is to occupy a dedicated interlace, and the COT initiating UE may communicate a padding signal on a PSFCH resource within the dedicated interlace.

  • Patent number: 12213126
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.
