Embodiment 1

[0100] Embodiment 1: In this embodiment, RRC signaling is used to configure the SPS window corresponding to the downlink SPS. The specific process is as Figure 2A shown, including:

[0101] Step 21: SPS scheduling decision, details are as follows:

[0102] The base station determines to use the SPS for downlink transmission according to parameters such as Quality of Service (QoS for short) or service type corresponding to the downlink service of the terminal.

[0103] Step 22: RRC signaling configures relevant parameters of the downlink SPS, as follows:

[0104] The base station configures related parameters of downlink SPS for the terminal through RRC signaling, wherein parameter information of downlink SPS window length (referred to as semiPersistSchedWinowLength in this embodiment) is added to the RRC signaling. The content of the RRC signaling is shown in Table 1:

Abstract

The invention discloses a scheduling method and device, and equipment so that a problem that the time delay is increased when a V2X service is transmitted by using SPS resources because the V2X service arrival time does not match the SPS resources in the prior art can be solved. The method comprises: according to a configured SPS occasion and SPS window length in a transmission direction, an SPS window corresponding to the transmission direction is determined, wherein the SPS window ends with the SPS occasion; when a data arrival time in the transmission direction is determined to be located in an SPS window corresponding to the transmission direction, data are transmitted by means of SPS; and when the data arrival time in the transmission direction is determined to be beyond the SPS window corresponding to the transmission direction, data are transmitted by means of dynamic scheduling. Therefore, the signaling costs are minimized while the service delay requirement is met.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a scheduling method, device and equipment. Background technique [0002] In order to reduce the overhead of control signaling, in the Long Term Evolution (LTE for short) system, Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS for short) is introduced for services with basically the same data packet size and relatively regular arrival time intervals. ), and it is stipulated that a user equipment (User Equipment, referred to as UE) can only be configured with one set of SPS resources. The period of the SPS and the used SPS cell-level radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI for short) are configured by the radio resource control (Radio Resource Control, RRC for short). The base station notifies the UE of the SPS resource through scheduling signaling, and the scheduling signaling is transmitted through a physical...
