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 invention provides a half-static scheduling reassortment method and system; the method comprises the following steps: calculating a half-static scheduling reassortment period in half-static scheduling now construction; carrying out half-static period scheduling according to the half-static scheduling reassortment period; calculating transmitted data amount when a user terminal reaches the half-static scheduling reassortment period; determining whether to start a half-static scheduling reassortment activate authorization or not according to a relation between the transmitted data amount, a MCS lowering threshold, an error rate threshold and a PRB lowering threshold. The method and system consider delay demands of different business periods, and no resource predistribution processing is needed, thus reducing processing amount cost, and greatly reducing DSP processing time.

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 (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 receives the physical downlink control channel (PDSCH) data according to the resources authorized by activation When transmitting Physical Upl...
