Cooperative communication method and system, access network device, and user equipment
First Claim
1. A cooperative communication method, comprising:
- receiving, by an access network device, downlink data belonging to a first user equipment (UE);
determining that each supporting UE in a support list of the first UE stored at the access network device cannot serve as a current supporting UE of the downlink data due to a channel quality between the first UE and the respective supporting UE;
identifying a second UE as a potential supporting UE for the first UE in response to receiving, from the second UE, a pairing identifier associated with the first UE and information regarding channel quality between the first UE and the second UE, wherein the support list of the first UE excludes the second UE during the determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data;
adding, in response to the identifying the second UE as the potential supporting UE, the pairing identifier associated with the first UE, an identifier of the second UE and the information regarding the channel quality between the first UE and the second UE to the support list of the first UE;
establishing, in response to, and after, the determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data, and further in response to the adding the pairing identifier associated with the first UE to the support list of the first UE, a cooperative communication relationship between the first UE and the second UE by setting the second UE as the current supporting UE of the first UE;
sending the downlink data to the second UE, the sending the downlink data to the second UE causing the second UE to send the downlink data to the first UE; and
deleting the added information from the support list of the first UE in response to one of receiving a release request from the second UE or a report indicating a poor quality of the channel between the first UE and second UE.

Abstract
Embodiments of the present invention provide a cooperative communication method and system, an access network device, and a user equipment. The method includes, when a access network device receives downlink data belonging to a first user equipment UE, if it is determined that a supporting UE in a support list of the first UE cannot serve as a current supporting UE of the downlink data, establishing a cooperative communication relationship between a second UE and the first UE, that is, setting the second UE as the current supporting UE of the first UE. The second UE is another UE except the first UE and the supporting UE in the support list of the first UE. The downlink data is sent to the second UE, so that the second UE sends the downlink data to the first UE.

10. An access network device, comprising:
-
a processor; and a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for; determining when downlink data belonging to a first user equipment (UE) is received; determining that each supporting UE in a support list of the first UE stored in a memory of the access network device cannot serve as a current supporting UE of the downlink data due to a channel quality between the first UE and the respective supporting UE; identifying a second UE as a potential supporting UE for the first UE in response to receiving, from the second UE, a pairing identifier associated with the first UE and information regarding channel quality between the first UE and the second UE, wherein the support list of the first UE excludes the second UE during the determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data; adding, in response to the identifying the second UE as the potential supporting UE, the pairing identifier associated with the first UE, an identifier of the second UE and the information regarding the channel quality between the first UE and the second UE to the support list of the first UE; setting, in response to, and after, the determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data, and further in response to the adding the pairing identifier associated with the first UE to the support list of the first UE the second UE as the current supporting UE of the first UE; sending the downlink data to the second UE in response to setting the second UE as the current supporting UE of the first UE, the sending the downlink data to the second UE causing the second UE to send the downlink data to the first UE; and deleting the added information from the support list of the first UE in response to one of receiving a release request from the second UE or a report indicating a poor quality of the channel between the first UE and second UE. - View Dependent Claims (11, 12, 13, 14, 15, 26, 27, 28)

16. A user equipment, comprising:
-
a processor; and a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for; sending a pairing identifier associated with the first user equipment (UE) to an access network device; establishing a cooperative communication relationship with a first UE in response to a message from the access network device sent in response to the pairing identifier and information regarding channel quality between the first UE and the user equipment being received at the access network device, the message indicating that the access network device has received downlink data belonging to the first UE, the message further indicating that each supporting UE in a support list of the first UE stored at the network access device cannot serve as a current supporting UE of the downlink data due to a channel quality between the first UE and the respective supporting UE, the message further indicating that the network access device has determined the user equipment, which is not in the support list of the first UE during determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data, to be the current supporting UE of the first UE, the message further indicating the addition, to the support list of the first UE, in response to the determining the user equipment to be the current supporting UE of the first UE, of the pairing identifier associated with the first UE, an identifier of the user equipment and the information regarding the channel quality between the first UE and user equipment, wherein the cooperative communications relationship is established in response to the adding the pairing identifier associated with the first UE to the support list of the first UE; receiving downlink data that belongs to the first UE and is sent by the access network device; sending, to the first UE, the downlink data; and deleting, according to synthesis deletion information that is sent by the access network device, a synthetic layer configuration corresponding to the first UE, wherein the synthesis deletion information is synthesis deletion information that is sent to the user equipment after the access network device determines that the user equipment is inappropriate to serve as a supporting UE of the first UE in response to one of receiving a release request from the second UE or a report indicating a poor quality of the channel between the first UE and second UE and after the access network device deletes the added information from the support list of the first UE. - View Dependent Claims (17, 18, 19, 20)
