Abstract
In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes performing, at a relay node, Listen Before Talk (LBT). The communication control method includes storing the number of successes and a failure rate in a downlink direction of the performed LBT in a memory as statistical information, and storing the number of successes and a failure rate in an uplink direction of the performed LBT in the memory as statistical information. The communication control method includes transmitting, at the relay node, the statistical information to an upper node of the relay node.
Claims15
A communication control method used in a cellular communication system, the communication control method comprising:
- performing, by a user equipment, Listen Before Talk (LBT) on a shared spectrum;
- and
- transmitting to a base station, by the user equipment, a report including information indicating the number of LBT failures and information regarding to a radio state between the user equipment and the base station,
- wherein
- the LBT is performed by a lower entity in the user equipment, and
- the information indicating the number of LBT failures is based on the number of LBT failure indications received by an entity higher than the lower entity from the lower entity.
A cellular communication system comprising:
- a user equipment;
- and
- a base station, wherein
- the user equipment performs LBT (Listen Before Talk) on a shared spectrum,
- the use equipment transmits to a base station, a report including information indicating the number of LBT failures and information regarding to a radio state between the user equipment and the base station, wherein
- the LBT is performed by a lower entity in the user equipment, and
- the information indicating the number of LBT failures is based on the number of LBT failure indications received by an entity higher than the lower entity from the lower entity.
A user equipment comprising a transceiver circuitry and a processing circuitry operatively associated with the transceiver circuitry and configured to execute processes of:
- performing Listen Before Talk (LBT) on a shared spectrum;
- transmitting a report including information indicating the number of LBT failures and information regarding to a radio state between the user equipment and the base station, wherein
- the LBT is performed by a lower entity in the user equipment, and
- the information indicating the number of LBT failures is based on the number of LBT failure indications received by an entity higher than the lower entity from the lower entity.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute processing comprising:
- performing Listen Before Talk (LBT) on a shared spectrum;
- transmitting to a base station, a report including information indicating the number of LBT failures and information regarding to a radio state between the user equipment and the base station, wherein
- the LBT is performed by a lower entity in the user equipment, and
- the information indicating the number of LBT failures is based on the number of LBT failure indications received by an entity higher than the lower entity from the lower entity.
A chipset for a user equipment in a cellular communication system, the chipset comprising:
- performing Listen Before Talk (LBT) on a shared spectrum;
- and
- transmitting to a base station, a report including information indicating the number of LBT failures and information regarding to a radio state between the user equipment and the base station, wherein
- the LBT is performed by a lower entity in the user equipment, and
- the information indicating the number of LBT failures is based on the number of LBT failure indications received by an entity higher than the lower entity from the lower entity.
