Abstract: Methods and apparatuses for paging are disclosed. According to an embodiment, a paging related entity obtains first information about a probability at which each of at least one terminal device is paged at a paging occasion (PO). The paging related entity obtains second information about a first power consumption and a second power consumption spent by each of the at least one terminal device for detecting a wake up signal (WUS) and a paging message respectively. The paging related entity determines, for multiple applicable WUS to PO mapping parameters, corresponding power consumptions spent by the at least one terminal device in a paging time window (PTW), based on the first and second information. The paging related entity determines, as a target WUS to PO mapping parameter to be applied to the at least one terminal device, one of the multiple applicable WUS to PO mapping parameters corresponding to a lowest power consumption in a PTW.

Abstract: Embodiments of the present disclosure provide an efficient solution for control information transmission applicable in a Licensed-Assisted Access scenario. Particularly there is provided a method for control information transmission. The method is performed at a first communications device operable in both a licensed spectrum and an unlicensed spectrum. The method starts by checking whether there is a granted resource on a licensed carrier of the licensed spectrum. If there is a granted resource on the licensed carrier, then control information is transmitted via the granted resource on the licensed carrier to a second communications device that is operable in both the licensed spectrum and the unlicensed spectrum; otherwise, it is checked whether there is a granted resource on an unlicensed carrier of the unlicensed spectrum. If there is a granted resource on the unlicensed carrier, then transmission of the control information to the second communications device is attempted via the granted resource on the unlicensed carrier. Correspondingly, there is also provided an apparatus for control information transmission at a communications device operable in both a licensed spectrum and an unlicensed spectrum.

Abstract: The disclosure relates to a DRX method with TRM limitation. In one embodiment, the DRX method comprises steps of detecting a DRX wake sub-frame to be set for a first BS at least partially overlaps with a sub-frame allocated to a second BS, and removing a collision of the DRX wake sub-frame to the sub-frame allocated to the second BS without change to the sub-frame allocated to the second BS. There is also provided a user equipment using the DRX method. By removing the collision without change to the sub-frames allocated in accordance with TDM, the user equipment may work in the DRX mode well.
