Abstract
Embodiments of the present invention provide a coordinated transmission method and a device. The method includes: communicating, by a UE, with a macro base station in a subframe in a first subframe set; and communicating, by the UE, with a micro base station in a subframe in a second subframe set; where the subframe in the first subframe set and the subframe in the second subframe set do not overlap. Technical solutions of the present invention solve a problem that application of a CoMP transmission technology is limited.

A coordinated transmission method, comprising:
- communicating, by a user equipment (UE), with a macro base station in a subframe in a first subframe set;
- and
- communicating, by the UE, with a micro base station in a subframe in a second subframe set;
- wherein the subframe in the first subframe set and the subframe in the second subframe set do not overlap;
- wherein before the communicating, by the UE, with the macro base station in the subframe in the first subframe set, the method further comprises:
- receiving, by the UE, a first association relationship and a second association relationship sent by the macro base station, wherein the first association relationship comprises an identifier of a first logical channel associated with the first subframe set, the second association relationship comprises an identifier of a second logical channel associated with the second subframe set;
- and wherein
- the communicating, by the UE, with the macro base station in the subframe in the first subframe set comprises:
- sending, by the UE in a first uplink subframe in the first subframe set according to the first association relationship, data on a first radio bearer corresponding to the identifier of the first logical channel in the first association relationship to the macro base station, the first logical channel having a one-to-one correspondence with the first radio bearer;
- the communicating, by the UE, with a micro base station in a subframe in a second subframe set comprises:
- sending, by the UE in a second uplink subframe in the second subframe set according to the second association relationship, data on a second radio bearer corresponding to the identifier of the second logical channel in the second association relationship to the micro base station, the second logical channel having a one-to-one correspondence with the second radio bearer.

A user equipment, comprising:
- a first communication unit, configured to communicate with a macro base station in a subframe in a first subframe set;
- and
- a second communication unit, configured to communicate with a micro base station in a subframe in a second subframe set;
- wherein the subframe in the first subframe set and the subframe in the second subframe set do not overlap;
- wherein the user equipment further comprises:
- a first receiving unit, configured to receive a first association relationship sent by the macro base station, wherein the first association relationship comprises an identifier of a first logical channel associated with the first subframe set;
- and wherein
- the first communication unit is specifically configured to send, in a first uplink subframe in the first subframe set according to the first association relationship received by first receiving unit, data on a first radio bearer corresponding to the first logical channel in the first association relationship to the macro base station, the first logical channel having a one-to-one correspondence with the first radio bearer;
- a second receiving unit, configured to receive a second association relationship sent by the macro base station, wherein the second association relationship comprises an identifier of a second logical channel associated with the second subframe set;
- and wherein
- the second communication unit is specifically configured to send, in a second uplink subframe in the second subframe set according to the second association relationship received by second receiving unit, data on a second radio bearer corresponding to the second logical channel in the second association relationship to the micro base station, the second logical channel having a one-to-one correspondence with the second radio bearer.
