  • the resource allocation mode of the shared scheduling requires the transmission of relevant control information for each transmission, the overhead of the control information is excessive. Therefore, SPS technology can be used for real-time services with a fixed packet size and a certain arrival time interval, which can greatly reduce the control overhead.
  • SPS refers to: A scheduling method designed for a specific service that uses pre-allocated resources at fixed times and dynamically schedules at other times. Specifically, under the SPS, the specified resource block is periodically allocated to a fixed user within a certain time range to adapt to the characteristics of certain periodic and payload-fixed services, thereby saving resource allocation and indication.
  • the system overhead caused by the control information; and the retransmission of the SPS service data uses the dynamic scheduling method. Therefore, the scheduling method is called SPS.

  • the user can release the resources.
  • the implicit release is generally used for the uplink. That is, the user equipment (UE, User Equipment) sends the continuous two or more all-zero data packets, and the base station detects the release of the SPS resources.

  • Inconsistencies in allocation and release especially in the case of poor channel conditions, this inconsistency can lead to two undesirable outcomes:
  • the SPS bandwidth resource is released by itself. Due to the poor channel conditions, the evolved base station (eNB, evolved Node B) does not correctly receive the all-zero data packet, and the SPS bandwidth resource is still considered to be valid. As a result, the bandwidth resource cannot be allocated to other users, thereby wasting resources.
  • eNB evolved Node B
  • the UE After transmitting the all-zero data packet multiple times, the UE releases the SPS bandwidth resource by itself.
  • the eNB does not correctly receive the all-collected data packet because the channel condition is bad. Therefore, the eNB requests the UE to retransmit the data on the SPS bandwidth resource. At this time, since the UE has released the SPS bandwidth resource, the UE cannot obtain the retransmission instruction, thereby causing the eNB to release the bandwidth resource delay.

Abstract

La présente invention se rapporte à un procédé pour libérer la ressource de service de programmation semi-persistante (SPS, Semi-Persistent Scheduling). Le procédé selon l'invention comprend les étapes suivantes : un UE transmet un paquet nul à une station de base (BS) après qu'un service SPS a été accompli ; à réception du paquet nul, la BS exécute une validation ; si la validation réussit, la BS retourne un message d'accusé de réception (ACK) à l'UE ; si la validation échoue, la BS retourne un message d'accusé de réception négatif (NACK) à l'UE ; à réception du message ACK, l'UE libère la ressource de service SPS ; et, à réception du message NACK, l'UE continue de transmettre les paquets nuls jusqu'à ce que l'UE reçoive le message ACK ; à ce moment-là, l'UE libère la ressource de service SPS. La présente invention se rapporte d'autre part à un système pour libérer la ressource de service SPS. La solution technique de la présente invention permet de résoudre les problèmes liés au fait qu'un gaspillage de ressource et un retard dans la libération de ressource se produisent durant la procédure existante de libération de ressource de service SPS sur la liaison montante.
