Description

Method for processing persistent resources, terminal and base station

The present invention relates to the field of communications, and in particular, to a method, a terminal, and a base station for processing a persistent resource. Background technique

In a communication system, a base station (BS) refers to a device that provides services to a terminal. The base station communicates with the terminal through uplink and downlink. The downlink (forward) refers to the direction from the base station to the terminal, and the uplink (reverse) Refers to the direction of the terminal to the base station. Multiple terminals can simultaneously transmit data to the base station through the uplink, or can simultaneously receive data from the base station through the downlink.

In the process of developing communication standards, how to effectively reduce the control overhead of communication systems to increase the throughput of the entire system has attracted the attention of more and more companies. For services that are periodic and whose packet size and modulation and coding rate (MCS) are relatively unchanged, a Persistent Allocation (PA) method is usually used to manage resources. At the beginning of the periodic service, the base station allocates a fixed resource to the terminal, and sends a corresponding control message containing the PA allocated content to the terminal. The resource allocation message is sent only once at the beginning, and then the terminal uses the fixed resource allocated to it. Receiving or transmitting data, until the release of resources, or resource changes, or changes in channel conditions, etc., the PA allocation is terminated. It can be seen that the PA allocation method can greatly reduce the overhead of control messages for resource allocation.

In the process of developing the Institute for Electrical and Electronic Engineers (IEEE) 802 series of standards, a description of the resource allocation technology was made. The technology was originally designed to save on specific transmission cycles. The packet length is relatively fixed for the terminal resource allocation description overhead to improve system performance, including message definition, hole filling, resource de-allocation, resource allocation, and the like. However, due to resource persistent allocation messages (PA MAP) The transmission period is relatively long. Therefore, it is very important for the terminal to correctly receive the message. The terminal needs to feed back to the base station to confirm the reception of the MAP message. When the terminal receives the new PA allocation, it sends a positive feedback acknowledgement (ACK) message to the base station (which may also be called a correct response message); when the terminal decodes the MAP message, an error occurs, and a negative feedback (NACK) message is sent to the base station (also Can be called an error feedback message). The base station determines how to adjust the allocation of persistent resources according to the feedback situation of the terminal.

1 is a schematic diagram of resource usage when a terminal receives persistent allocation of downlink or uplink resources according to the related art, where (a) in FIG. 1 is a process in which a base station allocates downlink persistent resources to a terminal, as shown in (a) of FIG. The base station sends a resource persistent allocation message in the (k-4)th frame, and allocates downlink persistent resources to the terminals MS1, MS2, and MS3. Since the MS3 does not successfully receive the MAP message, the MS3 does not decode the base station in the (k- 4) The data transmitted on the downlink persistent resource of the frame causes waste of downlink resources. (b) in FIG. 1 is a process in which the base station allocates uplink persistent resources to the terminal, and the base station transmits a persistent allocation message in the (k-4) frame. The uplink persistent resources are allocated to the terminals MS1, MS2, and MS3. Because the MS1 does not successfully receive the MAP message, the MS1 does not send the uplink data on the uplink persistent resource of the (k-4) frame, which causes waste of uplink resources.

2 is a schematic diagram of resource block movement in the case where a terminal fails to receive a mapping message according to the related art, and FIG. 2 depicts a processing procedure for filling a resource hole. As shown in FIG. 2, the BS sends a MAP message in the Kth frame (Frame K) to instruct the MS1 to release the resource and the specific resource block position and size, and the BS indicates that the hole needs to be filled. At this time, the BS and the MS are filled according to the hole. Resource location to send and receive data. Specifically, MS2 and MS3 move their resource block locations to fill the holes caused by MS1 releasing resources. As shown in Figure 2, MS2 decodes the MAP message error in frame K. MS2 immediately stops data transmission and reception, and sends a NACK to the BS after two frames. The BS will send a new MAP message to indicate PA recovery (at frame K+4 time). ). The MS2 data is lost before the PA is restored. If MS2 parses MAP message error without stopping sending and receiving Data, then MS3 moves its resource block location and will conflict with the MS2 resource block location. MS2 and MS3 cannot send and receive data normally. In the process of filling the hole and moving the resource location, the new PA is started to be applied without the feedback acknowledgement of the MS receiving MAP message. Therefore, if the MAP message is decoded incorrectly, data loss or error may result.

An effective solution has not been proposed for the problem of data loss or error in the related art. Summary of the invention

Then, when the effective time of the resource persistent allocation message arrives, the terminal processes the persistent resource according to the resource persistent allocation message, which can solve the problem of system spectrum efficiency degradation.

Method embodiment 1

It should be noted that the steps shown in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and, although the logical order is shown in the flowchart, in some cases, The steps shown or described may be performed in an order different than that herein.

The embodiment of the present invention provides a method for processing a persistent resource. FIG. 10 is a flowchart of a method for processing a persistent resource according to an embodiment of the present invention. As shown in FIG. 10, the process includes the following steps S102 to S104:

Step S102, the terminal receives a resource persistent allocation message from the base station, where the resource holds The long allocation message is used to indicate that the base station pre-allocates or allocates persistent resources to the terminal.

Step S104: If the terminal receives the resource persistent allocation message from the base station, when the effective time of the resource persistent allocation message arrives, the terminal processes the persistent resource according to the resource persistent allocation message, where the effective time is used to indicate that the persistent resource is processed. The start time.

Method 1: Before the terminal receives the resource persistent allocation message from the base station, the base station allocates a persistent resource to the terminal by using a resource persistent allocation message, where the resource persistent allocation message carries a feedback channel index field that receives (including) the resource persistent allocation message successfully. After the terminal receives the resource persistent allocation message, if the base station does not successfully obtain the feedback information sent by the terminal on the feedback channel indicated by the feedback channel index, where the feedback information user indicates that the terminal successfully obtains the resource persistent allocation message, the base station considers that The terminal did not successfully receive the resource persistent allocation message.

The feedback channel is allocated to other terminals, if the base station successfully obtains on the data feedback channel If the data is successfully received, or the data reception fails, the base station may consider that the terminal does not successfully receive the resource persistent allocation message.

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.

This embodiment can be implemented in the following manner, where the first embodiment corresponds to the first embodiment and the second embodiment, the second embodiment corresponds to the third embodiment and the fourth embodiment, and the third embodiment corresponds to the fifth embodiment.

method one

The first method corresponds to the first embodiment and the second embodiment. The first method is: the base station allocates a persistent resource to the terminal by using a resource persistent allocation message, and the terminal performs the persistent resource according to the default configuration time of the resource persistent allocation message. The receipt or transmission of data (ie, the resource persistent allocation delay takes effect). The base station can send resource persistent allocation messages by unicast, multicast, or broadcast. It should be noted that the default configuration of the terminal and/or the base station may include the above-mentioned effective time.

The default time of the default configuration may be after the time when the terminal feeds back the information that the resource persistent allocation message is successfully received, or after the time when the base station receives the information that the terminal successfully receives the resource persistent allocation message.

In the time division duplex system, if the base station allocates the downlink persistent resource to the terminal, the effective time of the default configuration is not located in the downlink subframe that is consecutive to the downlink subframe in which the base station sends the resource persistent allocation message, that is, the effective time is located. And the downlink subframe that is consecutive to the downlink subframe in which the base station sends the resource persistent allocation message.

FIG. 3 is a flowchart (default effective time) of the resource persistent allocation delay effective according to the embodiment of the present invention. As shown in FIG. 3, the process includes the following steps S302 to S304:

Step S302: The base station allocates a persistent resource to the terminal by using a resource persistent allocation message. Step S304: After receiving the resource persistent allocation message sent by the base station, the terminal is configured according to the default The effective time of the resource persistent allocation message, when the effective time arrives, the persistent resource is used to receive or send the data.

The flow shown in FIG. 3 will be further described below with reference to the first embodiment and the second embodiment.

Embodiment 1

4 is a schematic diagram of resource delay usage when a terminal receives a persistent allocation of downlink or uplink resources according to an embodiment of the present invention. In the time division duplex system shown in (a) of FIG. 4, the base station is in a kth frame (frame k ). The downlink persistent resources are allocated to the terminals MSI, MS2, MS3 through the control message (Persistent Allocation Advanced-MAP, PA Α-ΜΑΡ), in order to prevent the MSI, and/or MS2, and/or MS3 from successfully obtaining the PA A-MAP message. The waste of persistent resources allocated in k, therefore, the base station delays the use of persistent resources allocated for the above terminal, assuming that the standard default configuration time is 3 frames, the downlink persistent resources allocated by frame k are in frame (k+3) In effect, if the base station receives the information of the successful receiving PAA-MAP fed back by the MSI and MS2 on the uplink feedback channel in the frame k (the feedback channel can also be located on other subsequent frames), the PAA-MAP is successfully received without the feedback from the MS3. The information in the frame ( k+3 ) only retains the downlink persistent resources allocated for MS1 and MS2, and the downlink persistent resources previously allocated to MS3 can be Other end-use dispensing.

The above example process can also be in the form of a subframe or a superframe. The same process is also applicable to a frequency division duplex and a half frequency division duplex system.

In a time division duplex system, when a downlink resource persistent transmission message is sent on the first subframe in a continuous downlink subframe set (there is no uplink subframe in the set), the effective time of the allocated downlink persistent resource is allocated. Will not be in the subframe collection.

Embodiment 2

In the time division duplex system shown in (b) of FIG. 4, the base station allocates uplink persistent resources to the terminals MS1, MS2, and MS3 through the PA A-MAP in the frame k, and the base station delays use as the terminal. For the persistent resource, the default time of the standard is 1 frame, and the uplink persistent resource allocated by the frame frame k is valid in frame ( k+1 ). If the base station receives the MS2 and MS3 feedback on the uplink feedback channel in frame k. Successfully receiving the information of the PA A-MAP without receiving the information of the PAA-MAP successfully received by the MS1. At this time, the base station can consider that the MS1 does not successfully receive the PA A-MAP information, and only retains in the frame (k+1). For the uplink persistent resources allocated to MS2 and MS3, the uplink persistent resources previously allocated to MS1 can be allocated to other terminals.

The above process can also be in units of subframe or superframe, and the above process is also applicable to frequency division duplex and half frequency division duplex systems.

Way two

The second method corresponds to the third embodiment and the fourth embodiment. The second method is: the base station allocates a persistent resource to the terminal by using a resource persistent allocation message, and the resource persistent allocation message includes an effective time field (the effective time field may also be an allocation period field, The time when the base station or the terminal starts to send or receive data on the persistent resource is related to the allocation period field, and the allocation period may be written as an allocation period. The terminal uses the persistent resource to receive data when the effective time determined by the effective time field is reached or Send (that is, the resource persistent allocation delay takes effect). The base station can send resource persistent allocation messages by unicast, multicast, or broadcast.

It should be noted that the above effective time field may directly or indirectly indicate the effective time.

The effective time may be after the time when the terminal feeds back the information of the resource persistent allocation message successfully, or after the time when the base station receives the information that the terminal successfully receives the resource persistent allocation message.

In a time division duplex system, if the base station allocates downlink persistent resources to the terminal, the effective time is not within the downlink subframe that is consecutive to the downlink subframe in which the base station transmits the resource persistent allocation message.

The second mode is described below with reference to FIG. 5. FIG. 5 is a flowchart of a resource persistent allocation delay effective according to an embodiment of the present invention (the message includes an effective time field), as shown in FIG. Steps S502 to S504 are as follows:

Step S502: The base station allocates a persistent resource to the terminal by using a resource persistent allocation message, where the resource persistent allocation message includes an effective time field;

Step S504: After receiving the resource persistent allocation message, the terminal determines, according to the effective time determined by the effective time field in the message, when the effective time arrives, the persistent resource is used for data reception or transmission.

The flow shown in Fig. 5 will be further described below with reference to the third embodiment and the fourth embodiment.

Embodiment 3

FIG. 6 is a schematic diagram of resource delay usage when a terminal receives a persistent allocation of downlink or uplink resources according to an embodiment of the present invention. In the time division duplex system shown in (a) of FIG. 6, the base station passes the control message PAA- in frame k. The MAP allocates a downlink persistent resource to the terminal MS1, MS2, and MS3, and the base station delays the use of the persistent resource allocated to the terminal. It is assumed that the effective time field in the PA A-MAP indicates that the persistent resource allocated for the frame is valid after two frames. The downlink persistent resource allocated by frame k is valid in frame ( k+3 ). If the base station receives the uplink receiving channel in frame k (the feedback channel can also be located on other subsequent frames), it receives the successful receiving PAA of MS1 and MS2 feedback. If the information of the MAP is not received by the MS3 and the PAA-MAP is successfully received, only the downlink persistent resources allocated for the MSI and the MS2 are reserved in the frame (k+3), and the downlink persistent resources previously allocated to the MS3 can be allocated. Used by other terminals.

The above example process can also be in units of subframe or superframe, and the above process is also applicable to frequency division duplex and half frequency division duplex systems.

Embodiment 4 In the time division duplex system shown in (b) of FIG. 6, the base station allocates uplink persistent resources to the terminals MS1, MS2, and MS3 through the PA A-MAP in the frame k, and the base station delays using the persistent resources allocated for the terminal, assuming The effective time field in the PAA-MAP indicates that the persistent resource allocated for the frame is valid in the next frame, and the uplink persistent resource allocated by the frame k is valid in the frame (k+1), if the base station is in the uplink feedback channel in the frame k. After receiving the information of the PA A-MAP successfully received by the MS2 and the MS3, and not receiving the information of the PA A-MAP successfully received by the MS1, the base station can consider that the MS1 does not successfully receive the PA A-MAP information, and the frame is in the frame. Only the uplink persistent resources allocated for MS2 and MS3 are reserved in (k+1), and the uplink persistent resources previously allocated to MS1 can be allocated to other terminals.

Way three

The third method corresponds to the fifth embodiment. The third method is: H has not obtained the persistent allocation resource and the resource persistent allocation message receiving the error feedback channel, and the following is the method for the resource shift delay to be effective when the persistent resource is allocated in the communication system.

The base station cancels the allocated persistent resources by the resource persistent allocation message and requests resource allocation. The qualified terminals of the one or more terminals that receive the resource persistent allocation message perform resource shifting according to the effective time of the default configuration. The qualified terminal refers to a terminal whose allocated persistent resource index is greater than, or smaller than, the cancelled persistent resource index. The base station can send resource persistent allocation messages by unicast, multicast, or broadcast. It should be noted that the default configuration of the terminal and/or the base station may include the above-mentioned effective time.

It should be noted that the effective time field may also be included in the resource persistent allocation message (the effective time field may also be an allocation period field, and the time when the base station or the terminal starts to send or receive data on the persistent resource is related to the allocation period field. The allocation period can be written as allocation period. The effective time field is used to indicate the effective time. The effective time of the default configuration may be after the time when the terminal feeds back the information of the resource persistent allocation message successfully, or after the time when the terminal feeds back the information of the resource persistent allocation message.

The mode 3 is described below with reference to FIG. 7. FIG. 7 is a flowchart of the persistence of the resource allocation delay time effective delay according to the embodiment of the present invention, and FIG. 7 depicts the implementation process of the resource persistent allocation delay effective, assuming that the terminal has obtained persistent allocation. The resource and resource persistent allocation message receives the error feedback channel. As shown in FIG. 7, the process includes the following steps S702 to S705:

Step S702: The base station cancels the allocated persistent resource by using a resource persistent allocation message and requests resource shifting.

Step S704, after the terminal receives the resource persistent allocation message sent by the base station, the terminal that meets the condition in the one or more terminals that receive the resource persistent allocation message is performed according to the effective time of the default configuration in the school, when the effective time arrives. Resource shift.

The flow shown in Fig. 7 will be further described below in conjunction with the fifth embodiment.

Embodiment 5

FIG. 8 is a schematic diagram of resource block delay movement in a case where a terminal fails to receive a mapping message according to an embodiment of the present invention. As shown in FIG. 8, the BS transmits a PA A-MAP including a resource shift required in the kth frame, indicating release. The resource block of MS1 and the location and size of the resource block, and indicate that other eligible MSs need to move their resource block locations to fill the holes caused by the release of the resource blocks. Assume that the standard default delay effective time is the next continuous resource usage period arrival time, that is, the (k+4)th frame.

As shown in Figure 8, MS1 and MS3 successfully receive the PA A-MAP sent by the base station. MS2 does not successfully receive the PA A-MAP sent by the base station. MS2 will send a feedback message NACK in the (k+2) frame to notify the BS. In the kth frame, both MS2 and MS3 receive data according to the original PA allocation. Correspondingly, the BS also sends data according to the original PA allocation.

MS3 will move the resource block in the (k+4)th frame and enable the new resource location to receive the data. Correspondingly, the BS also enables the new resource location to transmit data in the (k+4)th frame. For the MS2 that obtains the PA-MAP message in the (k + 4) frame, the resource block can be moved in the (k + 4)th frame and the new resource location is enabled to receive the data, and correspondingly, the BS is also in the ( k + 4 ) frames enable new resource locations to send data; or stop using persistent resources in the (k + 4)th frame and later.

For MS2 that does not obtain a PA-MAP message in the (k + 4)th frame, the persistent resource is stopped at the (k + 4)th frame and thereafter.

FIG. 9 is a flow chart of a method for processing a resource persistent allocation message receiving error according to an embodiment of the present invention. Assume that a terminal has obtained a persistent allocation resource and a data feedback channel. As shown in FIG. 9, the process includes the following steps S902 to S904:

Step S902, the base station cancels the downlink persistent resource allocated to the terminal by using the resource persistent allocation message, and does not temporarily allocate the data feedback channel allocated to the terminal to other terminals; Step S904, if the base station successfully obtains on the data feedback channel If the data is successfully received, or the data is received, the base station may consider that the terminal does not successfully receive the resource persistent allocation message.
