RSRP THRESHOLD DETERMINATION METHOD AND APPARATUS, AND COMMUNICATION DEVICE AND STORAGE MEDIUM
A method for determining a reference signal received power (RSRP) threshold is performed by a network device. The method includes: sending configuration information, wherein the configuration information is configured to indicate one or more RSRP threshold-related parameters corresponding to user equipment (UE) of at least one antenna structure; wherein RSRP thresholds corresponding to UEs of different antenna structures in a same frequency range (FR) are different.
METHOD AND DEVICE IN NODE USED FOR WIRELESS COMMUNICATION
The present application discloses a method and a device in a node for wireless communications. A first node receives a first signaling group, the first signaling group being used to indicate a first signature sequence group and a second signature sequence group; transmits a first signature sequence in a first time interval; and transmits a second characteristic sequence in a second time interval; whether the first signature sequence belongs to the first signature sequence group or the second signature sequence group is used for selecting the second signature sequence; any signature sequence in the first signature sequence group is associated with a shared channel resource unit in a first period. The present application avoids the situation where the first node persistently selects random access preambles without being associated with a shared channel resource unit, thus ensuring that the requirement on access delay for UE is satisfied.
POSITIONING ENHANCEMENT MECHANISM
Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for positioning enhancement mechanism. A first device determines that a third device is to transmit a positioning related message in a non-connected state. The first device transmits assistance information to a second device serving the third device. The assistance information comprises at least one of data size and a transmission periodicity for the positioning related message. By means of the assistance information, the base stations are provided with proactive knowledge of the positioning related message. In this way, the base station is capable of determining appropriate configurations for the SDT procedure. The terminal device may then transmit the positioning related message in the RRC NON-CONNECTED state via the SDT. As such, the efficiency of SDT procedure can be improved, while avoiding segmentation or subsequent transmission of the positioning report.

SUPPORTING TWO TIMING ADVANCES IN A SERVING CELL OF A WIRELESS SYSTEM
Some aspects relate to apparatuses and methods for a wireless system supporting two timing advances in a serving cell for a user equipment (UE) communicating with two different transmission reception points (TRPs). The UE can determine that a first timing advance (TA) group (TAG) and a second TAG are configured for a serving cell based on a configuration received from the base station; and further determine a first TA adjustment value based on a first timing advance command (TAC) and a second TA adjustment value based on a second TAC. The UE can select a TAC from the first TAC or the second TAC to be applied to an uplink transmission. The UE can further select, based the selected TAC, a TAG from the first TAG or the second TAG; and transmit the uplink transmission according to the selected TAC with the selected TAG.
