The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The following is a detailed description of an auxiliary communication method according to the first embodiment of the present invention. FIG. 1 is a flowchart of an auxiliary communication method according to Embodiment 1 of the present invention. The executive body of the auxiliary communication method is a CF UE. As shown in FIG. 1, the auxiliary communication method includes the following steps:

Step S101: Receive a resource management message sent by the base station.

The base station allocates a communication resource (first communication resource) for communication between the first UE and the at least one second UE, and then instructs the first UE base station to allocate the first communication resource by transmitting a resource management message to the first UE. The first UE is a CF UE, and the second UE is an AC UE. Communication resources are resources such as time slots or sub-frames or frequencies.

Step S102: Obtain, according to the resource management message, a first communication resource allocated by the base station for communication between the first UE and the second UE.

Since the CF UE serves one or more AC UEs, after the CF UE learns the first communication resource allocated by the base station for communication between the CF UE and the AC UE according to the resource management message, the CF UE needs to allocate the first to the base station. Communication resources are further allocated.

Step S103: All second UEs are allocated a second communication resource from the first communication resource. A fixed second communication resource is allocated to each second UE from the first communication resource. Each second communication resource corresponds to one AC UE, and the second communication resource can only be used by the corresponding AC UE.

For example, the CF UE serves AC UE1 and AC UE2, and the CF UE learns, according to the received resource management message, that the communication resource communicated between the CF UE and the AC UE served by the CF UE is the first subframe and the fifth subframe. frame. Then, the CF UE allocates the first part of the physical resource block (PRB) of the first subframe to the downlink of the AC UE1, and allocates the first part PR3 of the fifth subframe to the uplink of the AC UE1. The third part PRB of the first subframe is allocated to the uplink of the AC UE2, and the second part PRB of the fifth subframe is allocated to the downlink of the AC UE2. After the CF UE completes the allocation, the AC UE1 and the AC UE2 respectively communicate with the CF UE on the communication resources allocated by the CF UE.

It should be noted that the base station may allocate the CF UE for the CF UE and the fixed period.

Communication resources for communication between AC UEs. Similarly, the CF UE can also use the fixed period to the base station. The allocated communication resources are further allocated, and each AC UE is allocated a fixed communication resource for communicating with the CF UE.

Step S104: Send, to each second UE, a scheduling notification, where the scheduling notification is used to instruct each second UE to communicate with the first UE by using the second communication resource.

The CF UE instructs the AC UE to communicate with the first UE by using a fixed second communication resource allocated thereto by transmitting a notification to each AC UE.

With the auxiliary communication method provided by the first embodiment of the present invention, the CF UE learns the static communication resources allocated by the base station for communication between the CF UE and the AC UE, and the CF UE allocates a fixed communication resource to each AC UE for the CF. The UE communicates with the AC UE to ensure that the CF UE can establish communication with the AC UE, and the CF UE can use the corresponding communication resource to help the AC UE to communicate.

The following is a detailed description of an auxiliary communication method according to Embodiment 2 of the present invention, and FIG. 2 is a flowchart of an auxiliary communication method according to Embodiment 2 of the present invention. The execution body of the auxiliary communication method is a CF UE. As shown in FIG. 2, the auxiliary communication method includes the following steps:

Step S201: Receive a resource management message sent by the base station.

The base station allocates a first communication resource for communication between the first UE and the at least one second UE, and then instructs the first UE base station to allocate the first communication resource by transmitting a resource management message to the first UE. The first UE is a CF UE, and the second UE is an AC UE. The communication resources are resources such as time slots or sub-frames or frequencies.

In addition, the resource management message is further used to indicate an indication identifier that is allocated by the base station to each AC UE, and the indication identifier of each AC UE is used to indicate that each AC UE acquires the second communication resource. The second communication resource is used for communication between each AC UE and the CF UE.

The indication identifier may be specifically a Ce l l Rad i o Ne twork Temporary I dent i fy (CRNT I ). The base occupies one CRNT I for each AC UE, so that the AC UE listens on the first communication resource according to the allocated CRNTI to learn the second communication resource available for communication with the CF UE.

Step S202: Obtain, according to the resource management message, the first UE and the second UE allocated by the base station. The first communication resource that communicates between.

Step S 203: Obtain an indication identifier of each second UE according to the resource management message, allocate a second communication resource to each second UE from the first communication resource, and perform identification.

After receiving the resource management message, the CF UE first learns, according to the resource management message, the first communication resource allocated by the base station for communication between the CF UE and the AC UE, and each AC UE allocated by the base station to the CF UE service. CMTI. Each of the AC UEs is then allocated a dynamic second communication resource from the first communication resource, that is, each AC UE is allocated a different second communication resource at different times, so that the utilization of the first communication resource is higher. The CRNT I assigned to the corresponding AC UE is identified on the second communication resource assigned to each AC UE.

Step S204: Send a scheduling notification to each second UE, where the scheduling notification is used to indicate that each second UE monitors the indication identifier allocated to the second UE on the first communication resource.

Each AC UE corresponds to a unique CRNTI. When the AC UE listens to the corresponding CRNT I in the first communication resource according to the scheduling notification, it can learn that the communication resource where the CRNTI is located is allocated to the AC UE for use with the CF UE. The second communication resource of the communication, the AC UE communicates with the CF UE by using the communication resource where the corresponding CRNTI is located.

For example, the CF UE serves AC UE 1 and AC UE2, and the CF UE learns, according to the received resource management message, that the communication resource that the base station performs communication between the CF UE and the AC UE served by the CF UE is the first subframe, and the third Subframe and fifth subframe. And it is known that the CRNTI allocated by the base station to the AC UE1 is CRNT I 1 , and the CRNTI allocated to the AC UE 2 is CMT I 2 . At a certain moment, the CF UE allocates the third subframe to the AC UE 1 and allocates the first subframe to the AC UE 2, then identifies the C RN T 1 1 in the third subframe, and identifies the CRNTI 2 in the first subframe. The CF UE then sends a scheduling notification to the AC UE1 and the AC UE2 to instruct the AC2 UE1 to listen to the CRNT I1 in the first subframe, the third subframe, and the fifth subframe, indicating that the AC UE2 is in the first subframe, and the third The CRNTI 2 is monitored on the subframe and the fifth subframe. When AC UE 1 is in the first When the three subframes are monitored to CRNTI1, the third subframe is used to communicate with the CF UE. When the AC UE2 listens to the CRNTI2 in the first subframe, the first subframe is used to communicate with the CF UE. At each moment, the CF UE re-allocates the communication resources allocated by the base station for communication between the CF UE and the AC UE according to the current situation, so that the AC UE communicates with the CF UE by using different communication resources at different times.

With the auxiliary communication method provided by the second embodiment of the present invention, the static communication resource allocated for communication between the CF UE and the AC UE is obtained according to the resource management message, and the CF UE allocates dynamic communication resources for each AC UE. After the CF UE communicates with the AC UE to ensure that the CF UE and the AC UE establish a connection, the CF UE can use the corresponding communication resource to help the AC UE to communicate.

The following is a detailed description of an auxiliary communication method according to Embodiment 3 of the present invention, and FIG. 3 is a flowchart of an auxiliary communication method according to Embodiment 3 of the present invention. The main body of the auxiliary communication method is a base station. As shown in FIG. 3, the auxiliary communication method includes the following steps:

Step S301: Receive a resource management message sent by the base station.

The resource management message is specifically used to indicate an indication identifier that is allocated by the base station to the CF UE, and the indicator identifier of the CF UE is used by the CF UE to acquire the first communication resource.

The indication identifier may be specifically a temporary identifier of the cell wireless network (Cell Radio)

Network Temporary Identify , CRNTI ). The base station allocates one CRNTI for each CF UE, so that the CF UE listens on the communication resource used for communication between the base station and the CF UE according to the allocated CRNTI, so as to know that the base station allocates the CF UE and the AC UE. The first communication resource to communicate.

In addition, the resource management message is further used to indicate an indication identifier that is allocated by the base station to each AC UE, and the indication identifier of each AC UE is used to instruct each AC UE to acquire the second communication resource. Second communication Resources are used for communication between each AC UE and the CF UE.

The base station allocates one CRNT I to each AC UE, so that the AC UE listens on the first communication resource allocated by the base station according to the allocated CRNT I to learn the second communication resource available for communication with the CF UE.

In step S302, the indication identifier of the first UE is obtained according to the resource management message, and the first communication resource allocated by the base station for communication between the first UE and the second UE is obtained according to the indication identifier of the first UE.

First, the CRNTI allocated by the base station to the CF UE is obtained according to the resource management message.

And then, according to the indication of the resource management message, the CRNT I allocated to the CF UE by the monitoring base station is performed on the communication resource used by the CF UE to communicate with the base station, and the communication resource of the CRNT I corresponding to the CF UE is allocated to the CF UE by the base station. The first communication resource in communication with the AC UE.

Step S 303: Obtain an indication identifier of each second UE according to the resource management message, allocate a second communication resource to each second UE from the first communication resource, and perform identification.

The CF UE allocates a dynamic second communication resource to each AC UE from the first communication resource by knowing, according to the received resource management message, the first communication resource allocated by the base station for communication between the CF UE and the AC UE, that is, Each AC UE is allocated a different second communication resource at different times so that the utilization of the first communication resource is higher. A CRNTI allocated to a corresponding AC UE is identified on a second communication resource allocated to each AC UE.

Step S304: Send, to each second UE, a scheduling notification, where the scheduling notification is used to indicate that each second UE monitors the indication identifier allocated to the second UE on the first communication resource.

Each AC UE corresponds to a unique CMTI. When the AC UE listens to the corresponding CRNT I in the first communication resource according to the scheduling notification, it can learn that the communication resource where the CRNTI is located is allocated to the AC UE for use with the CF UE. The second communication resource of communication, the AC UE uses its corresponding The communication resource on which the CRNTI is located communicates with the CF UE.

For example, the CF UE serves AC UE1 and AC UE2, and the CF UE learns that the CRNTI allocated by the base station to the CF UE is CRNTI0 according to the received resource management message, and learns that the CRNTI allocated by the base station to the AC UE1 is CRNTI1, and the CRNTI allocated to the AC UE2. For CMTI2. First, the CF UE resource management message listens to the communication resource with CRNTI 0 on the communication resource used for communication between the CF UE and the base station, and obtains the first subframe through the monitoring, and the third subframe and the fifth subframe have the CRNTI. 0. The communication resources currently allocated by the base station for communication between the CF UE and the AC UE are a first subframe, a third subframe, and a fifth subframe. Then, the CF UE allocates the third subframe to the AC UE1, allocates the first subframe to the AC UE2, identifies the CRNTI1 in the third subframe, identifies the CRNTI2 ₀ in the first subframe, and then the CF UE sends the scheduling to the AC UE1 and the AC UE2. The notification is used to indicate that the AC2 UE1 listens to the CRNTI1 in the first subframe, the third subframe, and the fifth subframe, and instructs the AC UE2 to listen to the CRNTI2 in the first subframe, the third subframe, and the fifth subframe. When the AC UE1 listens to the CRNTI 1 in the third subframe, it communicates with the CF UE by using the third subframe. When the AC UE2 listens to the CRNTI2 in the first subframe, it communicates with the CF UE by using the first subframe. The communication resources allocated by the base station for communication between the CF UE and the AC UE may be different at each moment, and the CF UE allocates the communication resources allocated by the base station for communication between the CF UE and the AC UE according to the current situation. So that the AC UE communicates with the CF UE with different communication resources at different times.
