A short cycle configuration method The method includes: for a plurality of discontinuous reception (DRX) groups of a user equipment, configuring, by a base station, a DRX short cycle parameter of the DRX group for a first frequency band and/or the DRX group for a second frequency band; where a frequency of the first frequency band is higher than a frequency of the second frequency band.

Provided are a method and device for providing power preference information in a wireless communication system. A terminal according to an embodiment of the disclosure may identify the necessity for transition from a radio resource control (RRC) connected mode and transmit, to a base station, a connection release request message including state information preferred by the terminal. In this case, the state information preferred by the terminal may include information indicating whether a state preferred by the terminal is an idle mode, an inactive mode, a connected mode, or a random mode, and the random mode may indicate that the terminal prefers to be released from the connection mode but there is no preferred mode among the idle mode and the inactive mode.

Embodiments of the present disclosure relate to failure recovery for serving cell. A terminal device detects a failure on a serving cell of the terminal device. If the beam failure is detected, the terminal device transmits information concerning the detected failure to a network device. The network device is associated with the serving cell. The terminal device disables further transmission of the information to the network device.

A wireless communication method is described for managing packet data convergence protocol (PDCP) service data unit (SDU). The method can include receiving, at a first protocol layer of a first communication device, a first service data unit (SDU) and a second service data unit (SDU) for a source from a second protocol layer for transmission to a second communication device. The method can also include starting a first timer with a first initial value for the first SDU, and starting a second timer with a second initial value for the second SDU. The second initial value can be different from the first initial value in response to determining that the second SDU is to be routed differently from the first SDU to the second communication device.

A system and method provide for receiving an indication that a user device has been inactive; accessing a configuration table; identifying, based on the configuration table, a number of user devices that can be in an RRC inactive state; determining a current number of user devices that are in the RRC inactive state; transitioning the user device to the RRC inactive state when the current number of user devices is less than the threshold number of user devices; determining a priority associated with the user device when the current number equals the threshold number; and transitioning the user device to the RRC inactive state or an RRC idle state based on the priority of the user device.
