Embodiment 1

[0086] The following takes a specific SPS reconfiguration method as an example to describe the implementation process of an embodiment of the present invention in detail, see figure 2 .

[0087] Step 201: when the SPS bearer of the UE is newly established, calculate the SPS reconfiguration period.

[0088] In this step, it is necessary to calculate the SPS reconfiguration period according to the SPS service period of the UE, and the calculation method is as follows:

[0089]

[0090] Since the VoIP voice service delay is generally required to be less than 100ms, according to this calculation method, for the case where the SPS service period is less than or equal to 60ms, the SPS reconfiguration period is about 50-60ms; for the case of greater than 60ms, the SPS reconfiguration period is the SPS service period . This can ensure that the data that has not been scheduled in the previous SPS reconfiguration cycle can be scheduled within the time delay required by the VoIP se...

Abstract

The present invention provides a semi-static scheduling reconfiguration algorithm and system, including: calculating the semi-static scheduling reconfiguration period when the semi-static scheduling is newly established; performing semi-static periodic scheduling according to the semi-static scheduling reconfiguration period; when the user terminal When the semi-persistent scheduling reconfiguration period arrives, calculate the amount of data to be transmitted; judge whether to initiate a semi-persistent scheduling reconfiguration activation authorization according to the relationship between the amount of data to be transmitted, the MCS down-regulation threshold, the bit error rate threshold, and the PRB down-regulation threshold. The invention takes into account the time delay requirements of different business cycles, and does not require resource pre-allocation processing, reduces the resulting processing overhead, and greatly reduces the processing time of the DSP.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a semi-persistent scheduling reconfiguration method and system. Background technique [0002] Since Voice over Internet Protocol (VoIP) voice services are periodic, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) can be used to send a semi-persistent scheduling on the physical downlink control channel (Physical Downlink Control Channel, PDCCH). activated, the user terminal (User Equipment, UE) saves the resource allocation. When the PDCCH semi-persistent scheduling release instruction is not received or the SPS service cycle that does not meet the implicit release condition, the downlink receives the physical downlink shared channel (Physical Downlink Control Channel, PDSCH) data according to the resources allocated by activation, and the uplink transmits according to the resources authorized by the activation For Physical Uplink Shared Channel (PUSCH...
