摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

摘要： Methods, systems, and devices for wireless communications are described. The method may include a first wireless device transmitting, to a third wireless device associated with a signal relaying device, a first message querying whether the third wireless device is able to establish a first communications link with a second wireless device. The first wireless device may receive, from the third wireless device, signaling indicative of whether the third wireless device is able to establish the first communications link with the second wireless device and communicate with the second wireless device via a second communications link using a signal relaying device of the one or more signal relaying devices associated with the third wireless device based on the signaling.

摘要： Methods, systems, and devices for wireless communications are described in which a receiving device, such as a receiving user equipment (UE) or vehicle, may provide channel state information (CSI) in which two or more parameters associated with the CSI are provided in a single joint indication. A transmitting device may transmit one or more reference signals and the receiving device may perform one or more measurements on the received reference signal(s). Based on the one or more measurements, the receiving device may determine one or more CSI parameters, such as a rank indicator, channel quality indicator, precoding matrix indicator, or combinations thereof, that may be provided to the transmitting device in a joint indication.

摘要： Certain aspects of the present disclosure provide a method for wireless communications between a first UE and a second UE. The method includes, at the first UE, receiving, from the second UE, a paging indication message on a sidelink channel, the paging indication message associating the first UE with one or more resources of a common resource pool that includes a plurality of resources for communication on the sidelink channel. The method further includes, based on the received paging indication message, monitoring the one or more resources for a message from the second UE.

摘要： Methods, systems, and devices for wireless communications are described. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) in a vehicle-to-everything (V2X) system may receive configuration information from an assisting node, such as a roadside unit (RSU), for calculating location information for a target UE in the V2X system. The assisting node may reflect one or more radar signals from the UE towards the target, and from the target back towards the UE according to the configuration information. That is, the assisting node may modify one or more waveform parameters of the reflection according to the configuration information. The UE may calculate location information for the target based on the reflection, such as by classifying the target as non-line-of-sight (NLOS) based on modified waveform parameters, location information of the assisting node, or both.

摘要： Methods, systems, and devices for wireless communications are described. In one aspect, a base station may transmit an indication of a communications mode capability associated with establishing a connection with the base station, and a user equipment (UE) may establish a connection with the base station if the UE has the communications mode capability. In this aspect, the base station may bar UEs that lack the communications mode capability from establishing a connection with the base station such that the base station may avoid configuring or scheduling communications differently for devices with different capabilities. In another aspect, a base station may transmit an indication of whether the base station operates in a full-duplex mode, a half-duplex mode, or both, and a UE may establish a connection with the base station based on whether the base station operates in the full-duplex mode, the half-duplex mode, or both.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for coordinated slot-based radar sensing. A first radar device, which may be a radar group leader, may broadcast information indicative of a wireless device group that includes the first wireless device. The first wireless device may receive, from a second wireless device that receives the broadcast information, a request to join the wireless device group that includes the first wireless device. The first wireless device may transmit, to the second wireless device based on the request, a grant or rejection to join the wireless device group that includes the first wireless device. The first wireless device may further transmit a transmission schedule to at least one wireless device of the wireless device group, where the at least one wireless device may include the second wireless device if the first wireless device transmits the grant.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmission-adjusting wireless node may transmit a first communication via a sidelink channel. The transmission-adjusting wireless node may receive, from a feedback-reporting wireless node, transmission-specific information relating to at least one of a channel quality of the sidelink channel or a power level for the transmission-adjusting wireless node. The transmission-specific information may be based at least in part on the first communication. The transmission-adjusting wireless node may adjust, based at least in part on the transmission-specific information, a transmission property of the transmission-adjusting wireless node to obtain an adjusted transmission property. The transmission-adjusting wireless node may transmit a second communication via the sidelink channel using the adjusted transmission property. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.
