Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may identify a set of interference measurement resources associated with signals received from a second UE. The first UE may perform one or more measurements on one or more signals received from the second UE within the set of interference measurement resources, and determine interference at the second UE associated with sensing signals transmitted by the first UE based on the one or more measurements. The first UE may compare the interference at the second UE to one or more thresholds, each associated with a respective sensing application at the first UE. The first UE may then transmit one or more sensing signals in accordance with respective sets of sensing signal parameters based at least in part on the comparing.

This disclosure discloses a beam switching method and an apparatus. A terminal device receives first indication information from a network device, where the first indication information indicates a first beam. Then, the terminal device performs one or more of the following behaviors based on the first beam: measuring downlink time-frequency offset information and path loss information corresponding to the first beam, sending, based on the first beam, a signal for uplink timing measurement, and receiving uplink timing adjustment information from the network device, where the timing adjustment information is determined based on the first beam. Further, the terminal device receives second indication information from the network device, where the second indication information indicates to switch to the first beam. The terminal device first measures timing information and/or the path loss information of the first beam to be switched to.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives information indicating mapping between an identifier of spatial relation information and a path loss reference signal by using higher layer signaling; and a control section that determines the path loss reference signal used for transmission power control, based on the indicated identifier of the spatial relation information and the mapping. According to one aspect of the present disclosure, parameters related to UL transmission power control can be appropriately determined.

A method for signal processing includes the following. A network device receives transmission configuration indication (TCI) state configuration information of a channel state information-reference signal (CSI-RS) from a network device, where the TCI state configuration information contains indication information of an SSB quasi co-located with the CSI-RS. The terminal device can determine transmit power of the CSI-RS according to a cell to which the SSB belongs.

A technique for wireless communications in a wireless system including: receiving, by a wireless device, a request to perform a pathloss reference signal (PLRS) measurement procedure in an unlicensed band, wherein the wireless device is configured to accumulate a first number of PLRS measurements within a PLRS switching period to perform the PLRS measurement procedure, wherein the first number of PLRS measurements is more than one, measuring, by the wireless device, a second number of PLRS signals during the PLRS switching period, wherein the second number is less than the first number of PLRS measurements within the PLRS switching period, determining, by the wireless device, to extend the PLRS switching period, and listening, by the wireless device, for a PLRS signal during the extended PLRS switching period.

The present application relates to improving a roaming service. In an example, user equipment (UE) initiates a cell selection process to choose between a first cell and a second cell. The UE evaluates a first uplink (UL) channel condition of the first cell and a second UL channel condition of the second cell based on the initiation. The UE selects the first cell or the second cell based on the evaluated first UL channel condition and second UL channel condition. The UE initiates a random access channel (RACH) procedure based on the selected first cell or second cell.

A carrier configuration method and a related device are provided. A first carrier and a second carrier are configured for an electronic device, and the second carrier is a supplementary uplink carrier of the first carrier. The method includes: The electronic device receives a first message, where the first message includes configuration information of a secondary cell, and the secondary cell includes at least a serving cell corresponding to the second carrier. The electronic device configures, based on the configuration information of the secondary cell, the serving cell corresponding to the second carrier. That the serving cell corresponding to the second carrier is configured includes: An uplink of the second carrier remains as a supplementary uplink of the first carrier, or the supplementary uplink of the second carrier is deactivated, or an uplink of the second carrier is aggregated with an uplink of the first carrier.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a path loss reference signal indication for determining a time of occurrence of an occasion associated with applying a path loss estimation. The UE may apply the path loss estimation at a time determined based at least in part on the time of occurrence of the occasion. Numerous other aspects are provided.

Some aspects relate to apparatuses and methods for calculating an uplink pathloss in a wireless communication system. A user equipment (UE) can be configured to perform operations for calculating the uplink pathloss. The operations can include determining a transmission power of a physical uplink shared channel (PUSCH) transmission for a UE, Txp.sub.PUSCH, where the PUSCH transmission is from the UE to a base station. The operations can further include determining a receiving power of a sounding reference signal (SRS) by the base station, Rxp.sub.srs; and further calculating the uplink pathloss based on the transmission power of the PUSCH transmission Txp.sub.PUSCH and the receiving power of the SRS Rxp.sub.srs.

A wireless channel type detection method and apparatus. The type of a channel can be identified on the basis of at least one of carrier phase slope consistency, a ratio of phase differences of carrier phases at different times, and a carrier path loss, i.e., the type of the channel is determined to be LOS transmission or NLOS transmission. Thus, the precision of positioning resolution can be effectively improved.
