Disclosed is a method for a terminal to receive a reference signal in a wireless communication system. In particular, the method comprises: receiving first information related to a reference signal configuration from a serving cell; receiving the reference signal from a neighbor cell on the basis of the first information; and obtaining second information on the timing of the reference signal on the basis of the sequence of the reference signal, wherein the reference signal is of a different type from a SS/PBCH block.

Wireless network operations can choose a long-term evolution (LTE) and 5G new radio (NR) dual connectivity deployment architecture using LTE as the anchor radio access network (RAN) node and adding mmWave NR as a secondary node when available. However, dual LTE/NR radios can consume more power and contribute more heat, thus degrading performance of radio frequency components. The overheating can be addressed by the user equipment (UE) sending an information message to indicate areas in which it requests to operate with reduced capability. Consequently, the network can determine whether to grant the request, or the UE can switch between NR to LTE depending on NR downlink channel quality.

A method of initiating handover of a wireless device includes determining one or more of a low battery condition, a low power headroom, and a high buffer status of a wireless device. The wireless device can be attached to a first access node deploying multiple radio access technologies over a first coverage area. The method further includes identifying a second access node deploying a single radio access technology over a second coverage area encompassing a location of the wireless device, and initiating handover of the wireless device from the first access node to the second access node based at least in part on the one or more of the low battery condition, low power headroom, and high buffer status of the wireless device. Systems and devices relate to initiating handover of a wireless device.

In a mobile station which communicates with a base station corresponding to a serving cell that is a cell in which the mobile station is located, of a plurality of cells, an acquirer is configured to acquire a situation of movement of the mobile station. A changer is configured to change a criterion used to determine whether to switch a communication destination from a first base station corresponding to the serving cell to a second base station corresponding to an adjacent cell neighboring the serving cell, in response to the situation of movement of the mobile station acquired by the acquirer and a positional relationship between the serving cell and the adjacent cell.

Aspects of the subject disclosure may include, for example, collecting network data for a plurality of cells of a cellular communication network, identifying a particular cell of the plurality of cells is in an un-responsive state, wherein the identifying is based on the network data, selecting a plurality of user equipment (UE) devices as UE test devices, forcing cell reselection attempts, handover attempts, or both, by the UE test devices to communicate with the particular cell, confirming the particular cell is in the un-responsive state based on failure of the cell reselection attempts or failure of the handover attempts, and communicating a restart signal from the processing system to cause the particular cell to restart to a responsive state. Other embodiments are disclosed.

The present disclosure relates to methods and communication apparatus for providing a network slice. In one example method where an access network device accessed by a terminal device does not support a network slice requested by the terminal device, the terminal device sends a network slice identifier, corresponding to a protocol data unit (PDU) session, to the access network device by including the network slice identifier in an radio resource control (RRC) message. The access network device may learn of the network slice identifier, and when the access network device does not support the network slice, search, in an access network device corresponding to a neighboring cell, for a target second access network device that supports the network slice.
