  • Publication number: 20250008434
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device determines a time window for monitoring a WUS from a network device. In response to receiving the WUS from the network device in the time window, the terminal device starts an on-duration operation of DRX based on a first time offset from an end of the reception of the WUS. In this way, a starting time of a DRX cycle may be dynamically determined, and a good tradeoff between latency and power consumption may be achieved. Accordingly, latency may be reduced and power consumption may also be reduced.

  • Publication number: 20250008383
    Abstract: A UE (10) provides information on potential S?eNB(s). The information is forwarded from an MeNB (20_1) to an M?eNB (20_2) such that the M?eNB (20_2) can determine, before the handover happens, whether the M?eNB (20_2) will configure a new SeNB (S?eNB) and which S?eNB the M?eNB (20_2) will configure. In one of options, the MeNB (20_1) derives a key S?-KeNB for communication protection between the UE (10) and the S?eNB (30_1), and send the S?-KeNB to the M?eNB (20_2). In another option, the M?eNB (20_2) derives the S?-KeNB from a key KeNB* received from the MeNB (20_1). The M?eNB (20_2) sends the S?-KeNB to the S?eNB (30_1). Moreover, there are also provided several variations to perform SeNB Release, SeNB Addition, Bearer Modification and the like, in which the order and/or timing thereof can be different during the handover procedure.
