Wireless communication method and wireless communication device

1. An electronic device performing communication with a counterpart communication device, comprising a processing circuit configured to:

when the electronic device and the counterpart communication device satisfy a predetermined condition, determine a state of a link between the electronic device and the counterpart communication device by measuring a link maintenance message transmitted by the counterpart communication device, without transmitting a feedback message in response to the link maintenance message,

wherein the link maintenance message is used for confirmation on link maintenance between the electronic device and the counterpart communication device, and

wherein the counterpart communication device determines disconnection of the link between the electronic device and the counterpart communication device based on a messy e from a base station.

2. The electronic device according to claim 1 , wherein the predetermined condition comprises at least one of the followings: the electronic device and the counterpart communication device have a mutual trust relationship, and a duration for which the electronic device and the counterpart communication device are connected with each other is greater than a predetermined value.

3. The electronic device according to claim 1 , wherein the link maintenance message comprises information for indicating, based on whether or not the predetermined condition is satisfied, whether or not the feedback message needs to be transmitted.

4. The electronic device according to claim 1 , wherein the processing circuit is further configured to:

when a measurement result is lower than a threshold, generate a message for releasing the link, which message is to be transmitted to the counterpart communication device.
