The present application provides a method and a device in a communication node for wireless communications. A communication node receives a first signaling; sets contents of a second message at a first moment; transmits a first radio signal, the first radio signal comprises the second message; at a second moment, as a response to not receiving a third message, determines performing a first procedure; the first signaling is used to determine a first time length; the second message comprises link maintenance related information; the third message is triggered by the second message; the second moment is after the first moment and its interval with the first moment is a second time length. Aiming at the problem of increased delay brought by relay communications, the present application proposes a scheme for delaying a determination of a first procedure to avoid triggering the first procedure to early.

Method and device in communication node for wireless communication

The present disclosure discloses a method and a device used in a communication node for wireless communications. A communication node receives multiple pieces of configuration sub-information, of which each piece of configuration sub-information includes one execution condition and one configuration set; in instances when the execution condition in first configuration sub-information is fulfilled, applies the configuration set in the first configuration sub-information, and transmits a first message; in instances when a first condition set is fulfilled after transmitting the first message, maintains a subset of the multiple pieces of configuration sub-information, the subset of the multiple pieces of configuration sub-information at least including second configuration sub-information; the first configuration sub-information is any of the multiple pieces of configuration sub-information, and the second configuration sub-information is one of the multiple pieces of configuration sub-information other than the first configuration sub-information.

Conditional reconfiguration release method and device used in communication node for wireless communication

Disclosed is a network interference coordination method in a co-primary spectrum sharing scenario. The method comprises the following steps: a first network and a second network negotiate an inter-network shared band, the shared band being in a shared spectrum pool; the first network evaluates inter-network interference; the first network determines whether to perform internal coordination, if internal coordination is performed, the first network performs internal coordination; if internal coordination is not performed, request the second network to perform inter-network interference coordination; the second network determines whether to perform internal coordination, if internal coordination is performed, the second network performs internal coordination; and if internal coordination is not performed, go back to the step of negotiating, by a first network and a second network, an inter-network shared band. The present invention can fairly and properly implement inter-network interference coordination in the co-primary spectrum sharing scenario.

Inter-network interference coordination method

An example implementation may include controlling receiving, in a first network, negotiation information for the asymmetric power usage of a shared spectrum; determining, in the first network, a minimum spectrum demand in dependence on the negotiation information; controlling receiving, in the first network, a minimum spectrum demand from at least one second network; and determining, in the first network, asymmetric power usage of the shared spectrum in dependence on the minimum spectrum demand from the at least one second network and the minimum spectrum demand of the first network.

Method, apparatus, system and computer program

A method comprises determining in a base station of a first cell of a first network that there is an inactive second cell of a second, different network which is a candidate cell for a user equipment and causing an activation message to be sent to cause the activation of said inactive second cell.

Method and apparatus for activating an inactive cell

Disclosed is a network frequency spectrum sharing method, a user terminal of the present network sending a network signal strength measurement report of the different network to a home base station; an operation management node of the present network, based on the network signal strength measurement report, calculating a network overlapping level indicator of the different network, and obtaining network overlapping topology-based information of the different network; and the two networks exchanging the network overlapping topology-based information, and calculating a policy for allocating shared frequency spectrum resources therebetween. The present invention can enable different networks to fairly and reasonably share frequency spectrum resources within a specified range, thus increasing a frequency spectrum utilization rate.
