Mobile station apparatus and base station apparatus in mobile communication system
A state managing unit configured to control a prescribed communication resource allocating process and a reception processing unit configured to receive a control element (CE) are included. The prescribed communication resource allocating process is a process of allocating a communication resource at a predetermined time interval, and the state managing unit suspends an uplink grant configured for the prescribed communication resource allocating process in a case that the reception processing unit receives an SCell Activation/Deactivation MAC CE for deactivating a secondary cell, or an sCellDeactivationTimer configured for the secondary cell expires, and the state managing unit reinitializes the uplink grant suspended, in a case that the reception processing unit receives the SCell Activation/Deactivation MAC CE for activating the secondary cell after the state managing unit suspends the uplink grant.
1. A communication method performed by a mobile station apparatus for communicating with a base station apparatus, the communication method comprising:
receiving a first message to allocate a first set of resources that occur at a first time interval for Uplink Shared Channel (UL-SCH) transmission;
receiving a second message to allocate a second set of resources that occur at a second time interval for the UL-SCH transmission;
receiving a Medium Access Control (MAC) Control Element (CE) after receiving the first message and the second message; and
determining whether to start or stop the UL-SCH transmission on the first set of resources and whether to stop the UL-SCH transmission on the second set of resources based on an indication of the MAC CE,
wherein:
the UL-SCH transmission on the first set of resources is started when the indication indicates re-initialization of the UL-SCH transmission on the first set of resources,
the UL-SCH transmission on the first set of resources is stopped when the indication indicates suspension of the UL-SCH transmission on the first set of resources, and
the UL-SCH transmission on the second set of resources is stopped when the indication indicates release of the second set of resources.
2. The communication method of claim 1 , wherein the UL-SCH transmission, which has been suspended when the MAC CE is received, on the first set of resources is started when the indication indicates the re-initialization of the UL-SCH transmission on the first set of resources.
3. The communication method of claim 1 , wherein the UL-SCH transmission, which has been initialized or re-initialized when the MAC CE is received, on the first set of resources is stopped when the indication indicates the suspension of the UL-SCH transmission on the first set of resources.
4. A mobile station apparatus for communicating with a base station apparatus, the mobile station apparatus comprising:
a memory having computer-readable instructions stored therein; and
at least one processor coupled to the memory, the at least one processor being configured to execute the computer-readable instructions to cause the mobile station apparatus to:
receive a first message to allocate a first set of resources that occur at a first time interval for Uplink Shared Channel (UL-SCH) transmission;
receive a second message to allocate a second set of resources that occur at a second time interval for the UL-SCH transmission;
receive a Medium Access Control (MAC) Control Element (CE) after receiving the first message and the second message; and
determine whether to start or stop the UL-SCH transmission on the first set of resources and whether to stop the UL-SCH transmission on the second set of resources based on an indication of the MAC CE,
wherein:
the UL-SCH transmission on the first set of resources is started when the indication indicates re-initialization of the UL-SCH transmission on the first set of resources,
the UL-SCH transmission on the first set of resources is stopped when the indication indicates suspension of the UL-SCH transmission on the first set of resources, and
the UL-SCH transmission on the second set of resources is stopped when the indication indicates release of the second set of resources.
5. The mobile station apparatus according to claim 4 , wherein the UL-SCH transmission, which has been suspended when the MAC CE is received, on the first set of resources is started when the indication indicates the re-initialization of the UL-SCH transmission on the first set of resources.
6. The mobile station apparatus according to claim 4 , wherein the UL-SCH transmission, which has been initialized or re-initialized when the MAC CE is received, on the first set of resources is stopped when the indication indicates the suspension of the UL-SCH transmission on the first set of resources.
