Abstract: Embodiments of the present disclosure provide method and apparatus for changing radio access technology. A method performed by a network device comprises obtaining channel estimation information of a terminal device; determining an uplink power value according to the channel estimation information and a number of antennas to be used; and transmitting the uplink power value to the terminal device periodically.

Abstract: Various embodiments of the present disclosure provide method and apparatus for managing a resource in a wireless communication system. A method implemented at a network device may comprise allocating, based on respective quality of service, QoS, priority of a plurality of terminal devices, respective automatic repeat request, ARQ, indicator channels for the plurality of terminal devices; transmitting the allocation result to the plurality of terminal devices; and transmitting respective ARQ indicators on the allocated respective ARQ indicator channels to the plurality of terminal devices.

Abstract: Method and apparatus are disclosed for implementing a nonstandard bandwidth at a network device. According to an embodiment, a first amount of physical resource blocks (PRBs) available in the nonstandard bandwidth is determined. A second amount of PRBs available in a standard bandwidth corresponding to the nonstandard bandwidth is determined. A central frequency shift of the nonstandard bandwidth relative to the standard bandwidth is determined based at least on the first amount of PRBs and second amount of PRBs. A network device comprising the apparatus is also disclosed.
