The present application discloses a method for positioning a terminal and a first terminal. The method comprises: a first terminal receiving a first reference signal sent by at least one second terminal, the first reference signal being a positioning reference signal of a sidelink; and the first terminal positioning a target terminal according to the first reference signal. The present application provides a brand-new positioning service in a communication scenario of a sidelink, and a positioning result for a target terminal can be obtained by interaction between different terminals.

A system, method and apparatus for mobile communications including sidelink transmissions is provided. A user equipment (UE) maintains a first interface between the first UE and a radio access network (RAN) infrastructure node, a second interface between the first UE and a second UE and a third interface between the first UE and a satellite node or an airborne node. The UE switches between interfaces according to a current connectivity state and based on signal attributes associated with individual interfaces.

Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support inter-user equipment (UE) cross-link interference (CLI) reduction. For example, a first UE may receive sidelink signaling from one or more other UEs and may generate measurement information associated with inter-UE cross link interference between the first UE and the one or more other UEs based on the sidelink signaling. Further, the first UE may transmit, to a network entity, an inter-UE cross link interference report that includes information indicative of a first set of one or more UEs from among the one or more other UEs, where each UE of the first set of one or more UEs is associated with respective measurement information of the measurement information that satisfies a threshold.

Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

The present application discloses a method and device for wireless communications, comprising receiving a first signaling, and the first signaling indicating a first RS resource set and a second RS resource set; executing a first link quality evaluation for a first BWP according to the first RS resource set; executing a second link quality evaluation for a first BWP according to the second RS resource set; wherein the first RS resource set and the second RS resource set are respectively associated with a first PCI and a second PCI; a first condition set is used for the first link quality evaluation, when all conditions in a first condition set are met, the first link quality evaluation is completed within a first evaluation period. The present application can better save power by controlling a first link quality evaluation and a second link quality evaluation.

A dynamic adjustment method for RS reception is provided. The dynamic adjustment method for RS reception includes the following steps. A processor of an apparatus may detect at least one channel condition to generate a detection result. Then, the processor may determine an RS reception scheduling based on the detection result. Then, the processor may perform an RS reception based on the RS reception scheduling to receive RSs from a network node.

A User Equipment, UE, in a wireless communication network receives, from a network node, a signal to activate a plurality of secondary cells, SCells. Responsive to receiving the signal, the UE uses a temporal characteristic and a spatial characteristic of a reference cell, selected from the plurality of SCells, to activate the reference cell and at least one other of the SCells in parallel.

The present invention relates to performing radio frequency based sensing based on channel state information (CSI), received signal strength indicator (RSSI), or a combination thereof based on a current context. A current context for performing radio frequency based sensing is determined and at least one of two nodes (26, 28, 30) of a radio frequency system (100) is configured for performing radio frequency based sensing based on CSI, RSSI, or a combination thereof based on the current context. The current context may be determined in real time. This may allow improving detection performance and/or reducing energy consumption in real time.

This application provides a PSCCH detection method and a communication apparatus. In the method, a first terminal device may detect a first PSCCH based on a resource included in a candidate resource set indicated by first indication information. This avoids overheads caused when the first terminal device needs to blindly detect the PSCCH, and helps reduce energy consumption. In particular, when a bandwidth is relatively large or there are a relatively large quantity of sub-channels, this can avoid overheads caused when the first terminal device needs to blindly detect the PSCCH.
