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 continuously released
(2) The counter of the base station is cleared but the counter of the user terminal is not cleared. After the counter of the user terminal reaches a certain threshold, the user terminal will implicitly release the semi-persistent scheduling resource, but if the base station needs to start again before then Scheduling user terminals without knowing that the user terminals have released semi-persistent scheduling resources, resulting in physical uplink shared channel (PUSCH, Physical Uplink Shared Channel) transmission errors

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 application discloses a semi-persistent scheduling resource release method and device. The method includes: receiving the data packet sent by the user terminal through the physical uplink shared channel, the counter of the base station counts the number of protocol data units not including the service data unit in the protocol data unit, and the counter of the base station is used for not including the service data unit in the protocol data unit When the number of protocol data units including service data units reaches a threshold, triggering the release of the scheduling authorization of the user terminal; the method also includes: after sending an explicit release instruction to the user terminal, synchronizing with the counter of the user terminal. The counter is cleared, and the explicit release instruction is used to release the scheduling authorization of the user terminal. The counter of the user terminal is used by the user terminal to count the number of PDUs excluding service data units in the PDUs. It can prevent the user terminal from continuously releasing semi-persistent scheduling resources or causing PUSCH transmission errors.

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...
