Abstract

The embodiments of the present disclosure provide a wireless communication method and a terminal device. The method includes: determining, by a terminal device, whether to activate neighboring cell measurement based on a measurement activation threshold and/or a cell blacklist; and determining, when the neighboring cell measurement is activated, a target cell for reselection based on a measurement result of at least one neighboring cell and the cell blacklist.

First claim

What is claimed is:

1 . A wireless communication method, comprising:
determining, by a terminal device, whether to activate neighboring cell measurement based on a measurement activation threshold and a cell blacklist; and determining, when the neighboring cell measurement is activated, a target cell for reselection based on a measurement result of at least one neighboring cell and the cell blacklist, wherein the measurement activation threshold comprises an intra-frequency measurement activation threshold, and said determining, by the terminal device, whether to activate the neighboring cell measurement based on the measurement activation threshold and the cell blacklist comprises: activating, by the terminal device, intra-frequency neighboring cell measurement when a serving cell of the terminal device does not meet the intra-frequency measurement activation threshold and the serving cell belongs to the cell blacklist; or, the measurement activation threshold comprises an inter-frequency measurement activation threshold, and said determining, by the terminal device, whether to activate the neighboring cell measurement based on the measurement activation threshold and the cell blacklist comprises: activating, by the terminal device, inter-frequency neighboring cell measurement when a serving cell of the terminal device does not meet the inter-frequency measurement activation threshold and the serving cell belongs to the cell blacklist.

2 . The method according to claim 1 , wherein the cell blacklist indicates at least one cell having a load higher than a specific threshold.

3 . The method according to claim 1 , wherein the cell blacklist is configured by a network device or obtained from a server.

4 . A terminal device, comprising a processor and a memory, wherein the memory has a computer program stored thereon, and the processor is configured to invoke and execute the computer program stored in the memory to:
determine whether to activate neighboring cell measurement based on a measurement activation threshold and a cell blacklist; and determine, when the neighboring cell measurement is activated, a target cell for reselection based on a measurement result of at least one neighboring cell and the cell blacklist, wherein the measurement activation threshold comprises an intra-frequency measurement activation threshold, and the processor is configured to invoke and execute the computer program stored in the memory to: activate intra-frequency neighboring cell measurement when a serving cell of the terminal device does not meet the intra-frequency measurement activation threshold and the serving cell belongs to the cell blacklist; or, the measurement activation threshold comprises an inter-frequency measurement activation threshold, and the processor is configured to invoke and execute the computer program stored in the memory to: activate inter-frequency neighboring cell measurement when a serving cell of the terminal device does not meet the inter-frequency measurement activation threshold and the serving cell belongs to the cell blacklist.

5 . The terminal device according to claim 4 , wherein the cell blacklist indicates at least one cell having a load higher than a specific threshold.

6 . The terminal device according to claim 4 , wherein the cell blacklist is configured by a network device or obtained from a server.

7 . The method according to claim 1 , wherein the serving cell not meeting the intra-frequency measurement activation threshold comprises a measurement result of the serving cell being higher than the intra-frequency measurement activation threshold.

8 . The method according to claim 7 , wherein said determining the target cell for reselection based on the measurement result of the at least one neighboring cell and the cell blacklist comprises:
determining, by the terminal device, at least one candidate intra-frequency neighboring cell from the at least one measured intra-frequency neighboring cell, each candidate intra-frequency neighboring cell not belonging to the cell blacklist; and selecting the target cell from the at least one candidate intra-frequency neighboring cell.

9 . The method according to claim 8 , wherein said selecting the target cell from the at least one candidate intra-frequency neighboring cell comprises:
determining, from the at least one candidate intra-frequency neighboring cell, an intra-frequency neighboring cell having a highest ranking as the target cell, at least one measurement result of the at least one candidate intra-frequency neighboring cell being ranked in a descending order.

10 . The method according to claim 1 , wherein the serving cell not meeting the inter-frequency measurement activation threshold comprises a measurement result of the serving cell being higher than the inter-frequency measurement activation threshold.

11 . The method according to claim 10 , wherein said determining the target cell for reselection based on the measurement result of the at least one neighboring cell and the cell blacklist comprises:
determining at least one candidate inter-frequency neighboring cell from the at least one measured inter-frequency neighboring cell, each candidate inter-frequency neighboring cell not belonging to the cell blacklist; and determining the target cell from the least one candidate inter-frequency neighboring cell based on a priority of the at least one candidate inter-frequency neighboring cell.

12 . The method according to claim 11 , wherein said determining the target cell from the least one candidate inter-frequency neighboring cell based on the priority of the at least one candidate inter-frequency neighboring cell comprises:
selecting, from the at least one candidate inter-frequency neighboring cell, an inter-frequency neighboring cell having a highest ranking as the target cell when the priority of the at least one candidate inter-frequency neighboring cell is same as a priority of the serving cell, at least one measurement result of the at least one candidate inter-frequency neighboring cell being ranked in a descending order.

13 . The method according to claim 11 , wherein said determining the target cell from the least one candidate inter-frequency neighboring cell based on the priority of the at least one candidate inter-frequency neighboring cell comprises:
selecting, from the at least one candidate inter-frequency neighboring cell, an inter-frequency neighboring cell whose measurement result meets a low-priority reselection threshold as the target cell when the priority of the at least one candidate inter-frequency neighboring cell is lower than a priority of the serving cell; or selecting, from the at least one candidate inter-frequency neighboring cell, an inter-frequency neighboring cell whose measurement result meets a cell selection criterion as the target cell when the priority of the at least one candidate inter-frequency neighboring cell is higher than the priority of the serving cell.

14 . The method according to claim 3 , wherein the cell blacklist is carried in a broadcast message from the network device.
