Embodiment 1

[0048] It should be noted that the steps shown in the flowcharts of the accompanying drawings may be performed in a computer system, such as a set of computer-executable instructions, and that although a logical order is shown in the flowcharts, in some cases, The steps shown or described may be performed in an order different than here.

[0049] An embodiment of the present invention provides a persistent resource processing method, Figure 10 is a flowchart of a persistent resource processing method according to an embodiment of the present invention, such as Figure 10 As shown, the process includes the following steps S102 to S104:

[0050] In step S102, the terminal receives a persistent resource allocation message from the base station, wherein the persistent resource allocation message is used to instruct the base station to pre-allocate or de-allocate persistent resources to the terminal.

[0051] Step S104, if the terminal receives the resource persistent allocation...

[0071] exist Figure 4 In the time division duplex system shown in (b), the base station allocates uplink persistent resources to the terminals MS1, MS2, and MS3 through PAA-MAP in frame k, and the base station delays the use of the persistent resources allocated for the above terminals, assuming the standard default time is 1 frame, the uplink persistent resource allocated by frame k takes effect in frame (k+1), if the base station receives the information of successfully receiving PA A-MAP fed back by MS2 and MS3 on the uplink feedback channel in frame k, If the information of successfully receiving the PAA-MAP fed back by MS1 is not obtained, the base station may consider that MS1 has not successfully received the PAA-MAP information, and only reserve the uplink persistent resources allocated for MS2 and MS3 in frame (k+1). The uplink persistent resources pre-allocated to MS1 can be allocated to other terminals.

[0072]In the above process, subframe or superframe may also...

Embodiment 3

[0083] Image 6 is a schematic diagram of delayed use of resources when a terminal receives persistent allocation of downlink or uplink resources according to an embodiment of the present invention. Image 6 In the time division duplex system shown in (a), the base station allocates downlink persistent resources to the terminals MS1, MS2, and MS3 through the control message PA A-MAP in frame k, and the base station delays using the persistent resources allocated for the above terminals. Assuming PA The effective time field in A-MAP indicates that the persistent resources allocated for this frame will take effect after 2 frames, and the downlink persistent resources allocated by frame k will take effect in frame (k+3). If the uplink feedback from the base station in frame k channel (the feedback channel can also be located on other subsequent frames) to receive the information of successfully receiving PAA-MAP fed back by MS1 and MS2, but not to receive the information of succe...

Abstract

The invention discloses a processing method, a terminal and a base station of persistent resources, wherein the method comprises the following steps of: receiving a resource persistent allocation message from the base station by the terminal, wherein the resource persistent allocation message is used for indicating the base station to pre-allocate or de-allocate the persistent resources to the terminal; when the effective time of the resource persistent allocation message is up, processing the persistent resources by the terminal according to the resource persistent allocation message, wherein the effective time is used for indicating the starting time for processing the persistent resources. Through the invention, the problem of data loss or errors is solved, thereby achieving the effect of reducing the data loss or the errors.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a persistent resource processing method, a terminal and a base station. Background technique [0002] In a communication system, a base station (Base Station, referred to as BS) refers to the equipment that provides services to the terminal. The base station communicates with the terminal through the uplink and downlink. The downlink (forward) refers to the direction from the base station to the terminal. Direction) refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In the process of formulating communication standards, more and more companies are paying attention to how to effectively reduce the communication system control overhead to increase the throughput of the entire system. F...
