Problems solved by technology

[0007] In the process of filling the hole and moving the resource position, the new PA has already been applied without the MS receiving the MAP message feedback confirmation. Therefore, once the MAP message is decoded incorrectly, the data will be lost.
A technical solution to this problem has not yet been proposed

example 1

[0051] In this example, if image 3 As shown, the BS sends a MAP message containing a new PA allocation at the current time T1, indicating the release of the resource block of MS1 and the location and size of the resource block, and indicating that other MSs will move their resource block positions to fill the resource block caused by the release of the resource block. At the same time, this MAP message indicates that the effective time of resource movement is T2.

[0052] according to image 3 , at time T1, MS2 did not correctly decode the above-mentioned MAP message sent by the BS, and MS2 will send a feedback message NACK at a subsequent time T3 to inform the BS. MS2 makes an error in decoding the MAP message at T1 but does not stop sending and receiving data.

[0053] according to image 3 , BS receives the above-mentioned NACK message sent by MS2, and then sends a MAP message including PA recovery information (information at T1 time) to MS, and MS2 and MS3 will move re...

example 2

[0057] In this example, if Figure 4 As shown, the BS sends a MAP message containing a new PA allocation at the current time T1, indicating the release of the resource block of MS1 and the location and size of the resource block, and indicating that other MSs will move their resource block positions to fill the resource block caused by the release of the resource block. At the same time, this MAP message indicates that the effective time of resource movement is T2.

[0058] according to Figure 4 , at time T1, MS2 did not correctly decode the above-mentioned MAP message sent by the BS, and MS2 will send a feedback message NACK at a subsequent time T3 to inform the BS. MS2 makes an error in decoding the MAP message at T1 but does not stop sending and receiving data.

[0059] according to Figure 4 After receiving the NACK message sent by MS2, the BS sends a MAP message including PA recovery information (information about T1 time) to MS.

[0060] according to Figure 4 , fr...

Abstract

The invention discloses a method and a system for adjusting a position of a resource block, wherein the method comprises the following steps: a base station informs the size and the position of a released resource block and the effective time of the move of the resource block to a terminal by a map message; and the terminal and the base station receive and send data by utilizing the resource block with an adjusted position when the map message reaches within the effective time. The invention can effectively solve the problem of data loss caused by a wrong map message of a decoding resource ofthe terminal.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and system for adjusting resource block positions. Background technique [0002] In the World Interoperability for Microwave Access (WiMAX) system, the information exchange between the base station (Base Station, BS) and the mobile station (MobileStation, MS) needs to allocate corresponding uplink and downlink resources. Resource Mapping (MAP) message to indicate. [0003] For services that are periodic and whose data packet size and modulation and coding rate (MCS) are relatively constant, a persistent allocation (Persistent Allocation, referred to as PA) method is adopted in the WiMAX system to manage resources. At the beginning of a periodic service, the BS allocates fixed resources to the MS, and sends a corresponding MAP message containing PA allocation to the MS. This resource allocation message is only sent once at the beginning, and then the MS uses th...
