Abstract

Embodiments of the present invention provide a control channel resource transmission method including: obtaining, by a user equipment, a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter; determining an antenna port according to the obtained configuration parameter; receiving, by using the antenna port, a control channel or a control channel element sent by the base station; and determining, by the base station, the antenna port according to the same configuration parameter as that of the user equipment, and sending, by using the antenna port, the control channel or the control channel element to the user equipment. The embodiments of the present invention are applicable to control channel resource transmission.

Claims

1. A method, comprising:

receiving, by a terminal device, an identity of the terminal device;

determining, by the terminal device, an index of an antenna port based on the identity of the terminal device and a configuration parameter of a candidate control channel set, wherein the configuration parameter comprises an aggregation level of the candidate control channel set; and

receiving, by using the antenna port identified by the index, a control channel or a control channel element.

2. The method according to claim 1, wherein:

the configuration parameter further comprises a sequence number of a first control channel element associated with the aggregation level.

3. The method according to claim 2, wherein

the identity of the terminal device is a radio network temporary identity (RNTI).

4. An apparatus, comprising:

a storage medium having processor-executable instructions stored thereon; and

a processor coupled to the storage medium;

wherein the executable instructions, when executed by the processor, causes the processor to;

receive an identity of the terminal device;

determine an index of an antenna port based on the identity of the terminal device and a configuration parameter of a candidate control channel set, wherein the configuration parameter comprises an aggregation level of the candidate control channel set; and

receive, by using the antenna port identified by the index, a control channel or a control channel element.

5. The apparatus according to claim 4, wherein:

the configuration parameter further comprises a sequence number of a first control channel element associated with the aggregation level.

6. The apparatus according to claim 5, wherein

the identity of the terminal device is a radio network temporary identity (RNTI).

7. A non-transitory computer readable medium, having computer-executable instructions stored thereon, wherein the instructions when executed by a hardware processor, causes the processor to implement operations including:

receiving, an identity of a terminal device;

determining, an index of an antenna port based on the identity of the terminal device and a configuration parameter of a candidate control channel set, wherein the configuration parameter comprises an aggregation level of the candidate control channel set; and

receiving, by using the antenna port identified by the index, a control channel or a control channel element.

8. The non-transitory computer readable medium according to claim 7, wherein:

the configuration parameter further comprises a sequence number of a first control channel element associated with the aggregation level.

9. The method according to claim 8, wherein

the identity of the terminal device is a radio network temporary identity (RNTI).
