As shown in FIG. 1, the wireless communication network 100 includes base stations 102-106 and terminal devices 108-122, wherein the base stations 102-106 can pass backhaul links with each other (e.g., lines between base stations 102-106) Communication is shown, which may be a wired backhaul link (eg, fiber optic, copper) or a wireless backhaul link (eg, microwave). The terminal devices 108-122 can communicate with the corresponding base stations 102-106 via a wireless link (as indicated by the broken line between the base stations 102-106 and the terminal devices 108-122).

The base stations 102-106 are configured to provide wireless access services for the terminal devices 108-122.

For example, as shown in FIG. 1, the base station 102 overlaps with the service coverage area of the base station 104, and the terminal device 112 is within the overlapping area, so the terminal device 112 can receive the wireless signals from the base station 102 and the base station 104. Base station 102 and base station 104 can simultaneously provide services to terminal device 112. For another example, as shown in FIG. 1, the service coverage areas of the base station 102, the base station 104, and the base station 106 have a common overlapping area, and the terminal device 120 is within the overlapping area, so the terminal device 120 can receive the base station.

With the rise of the Internet of Things (IOT) technology, more and more devices that did not have communication functions before, such as, but not limited to, household appliances, vehicles, tools, equipment, and service facilities, began to deploy wireless. The communication unit obtains a wireless communication function so that it can access the wireless communication network and accept remote control. Such devices have wireless communication functions because they are equipped with wireless communication units, and therefore belong to the category of wireless communication devices. In addition, the terminal devices 108-118 may also be referred to as mobile stations, mobile devices, mobile terminals, wireless terminals, handheld devices, clients, and the like.

The receiver algorithm is crucial to the terminal device, which not only affects the wireless communication performance of the terminal device, but also the complexity of the receiver algorithm directly affects the power consumption level of the terminal device, thereby directly affecting the standby time of the terminal device. After years of development, a variety of receiver algorithms have been available for terminal devices, such as, but not limited to, Zero Forcing (ZF) algorithm, Minimum Mean Square Error (MMSE) algorithm, interference suppression. Interference Rejection Combining (IRC) algorithm. In addition, the above algorithms can also be used in combination with various interference cancellation algorithms including, for example but not limited to, serial interference cancellation algorithms (Successive Interference Cancellation (SIC), Parallel Interference Cancellation (PIC) algorithm, etc. Different interference cancellation algorithms often have different performance and algorithm complexity when dealing with interference.

The CoMP base station may use various algorithms to schedule the terminal devices. These algorithms may include, for example but not limited to, Joint Transmission (JT) algorithm, Coordinated Scheduling (CS), Coordinated Beamforming (Coordinated Beamforming). , CB) algorithm, Dynamic Point Blanking (DPB) algorithm. Meanwhile, some of the above algorithms may further include a coherent scheduling algorithm and a non-coherent scheduling algorithm. For example, the JT algorithm further includes a coherent scheduling JT algorithm and a non-coherent scheduling JT algorithm. The coherent scheduling algorithm refers to the process of scheduling the terminal device, and the multiple CoMP base stations that provide services for the terminal device provide services to the terminal device in a cooperative manner, for example, how to perform scheduling on the terminal device by means of mutual negotiation. The non-coherent scheduling algorithm refers to that, in the process of scheduling the terminal device, multiple CoMP base stations that provide services for the terminal device provide services for the terminal device independently of each other, for example, independently scheduling the terminal device. It is not difficult to understand that the non-coherent scheduling algorithm may generate strong interference compared to the coherent scheduling algorithm, so the receiver algorithm of the terminal device is required to have strong anti-interference ability. The contents of the above receiver algorithm and scheduling algorithm have been clearly described in the prior art, and therefore will not be described herein.

As described above, the scheduling algorithm adopted by the CoMP base station may affect the signal receiving effect of the terminal device. For example, if the anti-interference performance of the receiver algorithm of the terminal device is not strong, and the CoMP base station adopts the non-coherent scheduling algorithm, a large amount of interference is generated, resulting in an error in receiving data. It can be seen that understanding the receiver algorithm used by the terminal equipment is crucial for CoMP to select an appropriate scheduling algorithm.

However, the capability information reported by the terminal device cannot accurately reflect the receiver algorithm used by the terminal device. Therefore, a solution is needed to enable the base station to know the receiver algorithm used by the terminal device. To this end, the embodiment of the present invention provides a technical solution, in which the terminal device reports the receiver algorithm used by the terminal device to the base station, so that the base station provides a more suitable service to the terminal device according to the receiver algorithm of the terminal device. The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Step 202: Generate capability indication information, where the capability indication information is used to indicate a receiver algorithm adopted by the terminal device.

In the specific implementation process, the above receiver algorithm is one of the following algorithms: ZF algorithm, MMSE algorithm, IRC algorithm, ZF algorithm based SIC algorithm, ZF algorithm based PIC algorithm, MMSE algorithm based SIC algorithm, based on MMSE algorithm PIC algorithm, SIC algorithm based on IRC algorithm and PIC algorithm based on IRC algorithm.

Step 204: Send the capability indication information.

According to the technical solution provided by the embodiment of the present invention, the terminal device reports the capability indication information to the access device, so that the access device can determine the receiver used by the terminal device according to the capability indication information. The algorithm accordingly selects a more suitable wireless communication scheme for the terminal device and improves data transmission efficiency.

In a specific implementation process, the capability indication information is sent by one of the following signaling:

Physical layer signaling;

Media access control layer signaling;

Radio resource control signaling.

Physical layer signaling is also referred to as Layer 1 (L1) signaling, which can typically be carried by a control portion in a physical layer frame. A typical example of L1 signaling is Downlink Control Information (DCI) carried in a physical downlink control channel (PDCCH) defined in the LTE standard. In some cases, L1 signaling may also be carried by the data portion of the physical layer frame. It is not difficult to see that the transmission period or signaling period of L1 signaling is usually the period of the physical layer frame, so this signaling is usually used to implement some dynamic control to transmit some frequently changing information, for example, through physical Layer signaling conveys resource allocation information.

Media Access Control (MAC) layer signaling belongs to Layer 2 signaling, which can typically be carried by, for example, but not limited to, a frame header of a Layer 2 frame. The foregoing frame header may also carry information such as, but not limited to, a source address and a destination address. In addition to the frame header, the second layer of frames usually also contains the frame body. In some cases, L2 signaling may also be carried by the frame body of the second layer frame. A typical example of Layer 2 signaling is the signaling carried in the Frame Control field in the frame header of the MAC frame in the 802.11 series of standards, or the MAC Control Entity (MAC CE) defined in some protocols. . The second layer frame can usually be carried in the data portion of the physical layer frame. The foregoing capability indication information may also be sent through other Layer 2 signaling other than the medium access control layer signaling.

Radio Resource Control (RRC) signaling belongs to Layer 3 signaling, which is usually some control message, and L3 signaling can usually be carried in the frame body of the second layer frame. The transmission period or control period of the L3 signaling is usually long, and is suitable for transmitting information that does not change frequently. For example, in some existing communication standards, L3 signaling is usually used to carry some configuration information. The foregoing capability indication information may also be sent through other layer 3 signaling other than RRC signaling. Since the receiver algorithm of the terminal device does not change frequently, the capability indication information can be transmitted through L3 signaling (for example, RRC signaling). In fact, in the LTE standard, the terminal device reports the capability of the terminal device to the access device, such as but not limited to the base station, through RRC signaling. For example, in the LTE standard, the access device can send a query to the terminal device. Request to query the capabilities of the terminal device. In this case, the terminal device can return capability indication information to the access device and report its various capabilities to the access device. The content of the RRC signaling carrying the above capability indication information is as follows:

In order to implement the technical solution provided by the embodiment of the present invention, the receiver algorithm used by the terminal device to report to the access device may be added to the foregoing RRC signaling, such as, but not limited to, the following information element (Information Element, IE):

UE-EUTRA-Capability-v1410-IEs::=SEQUENCE{

Ue-receiver-capability INTEGER(1..8)

}

The foregoing is only a schematic description of physical layer signaling, MAC layer signaling, RRC signaling, Layer 1 signaling, Layer 2 signaling, and Layer 3 signaling. Specific details about the three types of signaling. Reference can be made to the prior art, and therefore will not be described in detail herein.

In a specific implementation process, the capability indication information includes an index of the receiver algorithm. At the same time, the index of the receiver algorithm may also be specifically expressed as, or specifically used for, the indication of the performance of the receiver algorithm or the type of the receiver algorithm, wherein the performance of the receiver algorithm is related to the algorithm complexity and anti-interference performance, and receiving The types of machine algorithms include, for example but not limited to, the MMSE algorithm, the IRC algorithm, the SIC algorithm, the PIC algorithm, and the like described above. The correspondence between the receiver algorithm and its index can be as follows:

性能/类型Performance / type	算法algorithm
11	ZFZF
22	MMSEMMSE
33	IRCIRC
44	ZF+SICZF+SIC
55	ZF+PICZF+PIC
66	MMSE+SICMMSE+SIC
…...	…...

Table 1

In this case, the foregoing capability indication information may specifically include the performance of the receiver algorithm. The type of the receiver or receiver algorithm is used as an index to the receiver algorithm.

In a specific implementation process, the terminal device may send the capability indication information to the access device in the process of accessing the communication network, and report the receiver algorithm used by the terminal device. In addition, the terminal device may also send the capability indication information to the access device when receiving the query request of the access device, and report the receiver algorithm used by the terminal device.

After learning the receiver algorithm employed by the terminal device, the access device can select an appropriate scheduling algorithm according to the receiver algorithm. For example, if the receiver algorithm of the terminal device is the SIC algorithm, the CoMP base station may adopt a non-coherent scheduling algorithm with lower algorithm complexity; if the anti-interference performance of the receiver algorithm of the terminal device is not good, the CoMP base station needs to avoid using the non-interference. A coherent scheduling algorithm prevents large amounts of interference from causing errors in received data.

It should be noted that although the above is a description of the role of the receiver algorithm of the terminal device in selecting the CoMP base station scheduling algorithm by taking the CoMP base station as an example, those skilled in the art should understand that the receiver of the terminal device is known. The algorithm is also important for non-CoMP base stations. In fact, the above-mentioned base station or CoMP base station may be collectively referred to as an access device, and in addition to the above-mentioned base station or CoMP base station, the access device may also be other devices that provide services for the terminal device. In order to facilitate the understanding and more specific description of the technical solutions provided by the embodiments of the present invention, a base station or a CoMP base station is selected as a specific example of the access device in the description process. However, it should be understood by those skilled in the art that the base station and the CoMP base station mentioned herein may be more general unless otherwise specified or if they do not contradict the actual role or the internal logic in the related description. Described as an access device.
