Problems solved by technology

[0003] However, under the existing protocol, after the explicit release, there is no processing method for the counters of the base station and the counters of the user terminal
Therefore, under the existing technology, such a situation often occurs: (1) The counter of the base station is not cleared but the counter of the user terminal is cleared. After the counter of the base station reaches a specific threshold, the base station sends a display release command again, resulting in Semi-statically scheduled resources are continuousl

Embodiment Construction

[0026] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0027] refer to figure 1 , figure 1 It is a schematic structural diagram of an embodiment of the semi-persistent scheduling resource release system of the present application. The semi-persistent scheduling resource release system in this embodiment includes: a base station 110 and a user terminal 120 . Wherein, wireless communication can be performed between the base station 11...

Abstract

The invention discloses a semi-static scheduling resource releasing method and equipment. The method comprises the following steps that a receiving user terminal passes a data packet shared by a physical uplink sharing channel, a counter of a base station counts the number of protocol data units not including service data units in the protocol data units, and the counter of the base station is used for triggering and releasing the dispatching authorization of the user terminal when the number of the protocol data units not including service data units in the protocol data units reaches a threshold value; the method also comprises the steps that after an explicit release instruction is sent to the user terminal, the counter, maintaining the synchronism with a counter of the user terminal, of the base station is subjected to zero clearing, the explicit release instruction is used for releasing the dispatching authorization of the user terminal, and the counter of the user terminal is used for counting the number of the protocol data units not including service data units in the protocol data units by the user terminal. The PUSCH (physical uplink shared channel) transmission error capable of being caused by continuous release of semi-static scheduling resources by the user terminal can be prevented.

Description

technical field [0001] The present application relates to the communication field, in particular to a semi-persistent scheduling resource release method and device. Background technique [0002] In a communication system, in order to enable user terminals in a cell to obtain time-frequency resources for data transmission, scheduling is required. Scheduling is divided into dynamic scheduling and semi-persistent scheduling (Semi-Persistent Scheduling, SPS). Among them, in semi-persistent scheduling, there are two ways to release semi-persistent scheduling resources, implicit release and explicit release. At the end of the service, the base station sends an explicit release instruction to the user terminal to indicate the release of the semi-persistent scheduling resource. When the semi-persistent scheduling resource of the user terminal is successfully released, it enters into a silent period of communication, and the silent period means that the user terminal enters a non-ta...
