Abstract
A method for processing a medium access control entity, UE and a communication system. The method includes: establishing a corresponding medium access control entity by UE for a second connectivity, so that there exists dual connectivity between the UE and network side including a first connectivity and the second connectivity; wherein the medium access control entity of the second connectivity at least includes a multiplexing or de-multiplexing module and a logic channel prioritization module.
Claims7
A method for processing a medium access control (MAC) entity, comprising:
- establishing, by a User Equipment (UE), a corresponding MAC entity for a second connectivity, so that there exists dual connectivity between the UE and network side comprising a first connectivity and the second connectivity;
- wherein PDCP entity and RLC entity both exist in the first and second connectivity or PDCP entity and RLC entity exist in the first connectivity, RLC entity exists in the second connectivity;
- wherein a radio resource control (RRC) exists in the first connectivity and signaling radio bearer(s) (SRB(s)) is/are always transferred via the first connectivity, while the MAC entity of the second connectivity comprises a multiplexing or de-multiplexing module, a logic channel prioritization module, a control module, a random access control module and a hybrid automatic repeat request module;
- and
- releasing, by the UE, all radio resources related to the second connectivity, stopping timers related to the second connectivity and flushing hybrid automatic repeat request, HARQ, of the MAC entity of the second connectivity when the UE receives an instruction for releasing the second connectivity.
