  • Patent number: 11974223
    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications. For example, a wireless communications system may support New Radio (NR) cellular-vehicle to everything (C-V2X) communication. In some examples, a user equipment (UE) may receive a sidelink control channel for a sidelink transmission on a first set of symbols of a time slot (e.g., the first two or three symbols of a time slot). The UE may decode the sidelink control channel and disable one or more radio frequency (RF) components associated with processing the sidelink transmission on a second set of symbols of the time slot based on decoding the sidelink control channel. For example, the UE may disable one or more RF components if the UE determines the sidelink control channel is decoded unsuccessfully.

  • Patent number: 11949623
    Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

  • Publication number: 20240098694
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish one or more wireless connections for different subscriptions with a base station. The UE may receive an indication of a temporary mobile subscription identifier (TMSI) from the base station during a registration procedure. The UE may calculate a paging occasion (PO) based on the TMSI and may determine the PO fails to satisfy a threshold timing value. The UE may transmit one or more registration request to trigger additional registration procedures in which base station may transmit a new TMSI. The UE may calculate an updated PO based on the new TMSI. The UE may periodically receive one or more paging messages from the base station in a set of POs based on calculating the updated PO.

  • Patent number: 11895679
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

  • Publication number: 20230362972
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a message to be transmitted over a wireless channel, such as a vehicle-to-everything (V2X) system. The UE may determine a channel reservation limit for reserving resources on the wireless channel for the message based on a channel busy ratio for the wireless channel. The UE may determine that available resources are insufficient for both an initial transmission of the message and a retransmission of the message based on the channel reservation limit. The UE may reserve a resource on the wireless channel for the initial transmission of the message based on the available resources being insufficient for both the initial transmission of the message and the retransmission of the message.

  • Publication number: 20230239787
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the user equipment (UE) may adjust an operational mode of a circuit of the UE by selecting one or more parameters (e.g., power level or clock frequency or both). Adjusting parameter values may result in avoiding increased temperature. The UE may set an operational mode of a circuit based on a determination or a prediction of a number of blind decodes to be performed, a number of pending receive packets, or a number of transmitting UEs from which the UE will receive traffic. The UE may efficiently reduce unnecessary power expenditures and decrease temperature.
