A wireless roaming method and an apparatus, a storage medium and an access point device are disclosed. The wireless roaming method comprises: receiving, from an overlapping access point, first signal strength indication information that describes signal strength when a station transmits a data packet to the overlapping access point via a current channel, wherein the coverage of the overlapping access point overlaps with that of a current access point, the station accesses to the current access point, and the current access point operates on the current channel; measuring second signal strength information that describes signal strength when the station transmits a data packet to the current access point via the current channel; and sending the first signal strength indication information and the second signal strength indication information to the station, and/or generating a switching instruction based on the first signal strength indication information and the second signal strength indication information and sending at least the switching instruction to the station. The technical solution of the present disclosure can improve the efficiency of wireless roaming.

This document describes methods, devices, systems, and means for the transfer of radio bearer (RB) configurations from a Fifth Generation (5G) New Radio (NR) base station (121) to an Evolved Universal Terrestrial Radio Access (E-UTRA) base station (122). The 5G NR base station (121) configures an RB configuration to configure an RB for communication of Protocol Data Units between the 5G NR base station (121) and a user equipment (111). The 5G NR base station (121) determines to hand over the user equipment (111) to an Evolved Universal Terrestrial Radio Access (E-UTRA) base station and sends a Handover Request message for the user equipment (111) to the E-UTRA base station (122). The 5G NR base station (121) receives a Handover Request Acknowledge message from the E-UTRA base station (122) and transmits a 5G NR Radio Resource Control (RRC) message including an E-UTRA RRC message to the user equipment (111).

Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is arranged to implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel for control signals, the processor further monitoring subframes after the active time.

A cell reselection method, performed by an electronic device, includes: in a case of detecting that the electronic device performs ping-pong reselection in multiple cells, obtaining a number of reselections; in a case that the number of reselections reaches a preset number of times. The cell reselection method further includes determining a target cell among the multiple cells. Reference Signal Received Power (RSRP) fluctuation of the target cell is less than a preset fluctuation threshold. Reference Signal Received Quality (RSRQ) within a camping period is greater than a first threshold. The cell reselection method also includes setting an offset value and accessing the target cell according to the offset value.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.

A driving data collection method is disclosed, including: obtaining driving scenario requirement information (S203); determining at least one sensor on a vehicle based on the driving scenario requirement information (S204); and then, sending driving data collected by the at least one sensor to a network side device (S206).

Embodiments of apparatus and method for uplink data plane management are disclosed. In one example, a method for handover continuity can include buffering data packets at a user equipment based on a trigger event. The data packets can be mapped to first quality of service flows and associated with first radio resources at a source network node. The method can also include identifying second quality of service flows associated with second radio resources at a target network node. The method can further include remapping from the first quality of service flows to the second quality of service flows. The method can additionally include transmitting the buffered data packets from the user equipment toward the target node based on the remapping.
