Problems solved by technology

However, the radio resource control (RRC) of the existing system supports up to 8 SPS configurations, and one configuration cannot include all SPS intervals.
When the SPS service changes greatly and the existing SPS cycle cannot support it, it is necessary to re-configure the SPS and then activate it, which will cause a large service transmission delay
On the other hand, in the R15 system, different service types correspond to different sets of available carriers, and different service periods may vary greatly, and some service periods may be shorter (such as information sharing defined in NR scenarios), such as 20ms, and some The transmission period of some services is relatively large (regular software update, etc.), such as 1000ms, and the existing RRC configuration cannot configure the required SPS interval based on the carrier or service type
[0007] It can be seen that the existing SPS configuration methods cannot meet the configuration needs of multi-carrier multi-SPS scheduling intervals in the carrier aggregation scenario.

Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The core idea of ​​the present invention is: refine the SPS configuration granularity, independently configure the SPS configuration set for each carrier, that is, for each carrier, configure the carrier-specific SPS configuration set, so that the SPS scheduling intervals covered by all carriers are no longer Limited by the fact that RRC supports up to 8 SPS configurations, it can meet the configuration requirements of multi-carrier and multi-SPS scheduling intervals in the carrier aggregation scenario.

[0055] figure 1 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 1 As shown, the semi-persistent scheduling configuration method implemented in this embodiment mainly inclu...

Abstract

The invention discloses a SPS (Semi-Persistent Scheduling) configuration method and system, and the method comprises the steps: transmitting an RRC reconfiguration message to user equipment (UE) whenSPS configuration needs to be carried out, wherein the RRC reconfiguration message carries an SPS configuration set independently configured for each carrier; and enabling the UE to perform corresponding SPS configuration according to the RRC reconfiguration message. By adopting the method and the device, the configuration requirement of the multi-carrier multi-SPS scheduling interval in a carrieraggregation scene can be met.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a semi-persistent scheduling (SPS) configuration method and system. Background technique [0002] Semi-persistent scheduling (Semi-Persistent Scheduling, SPS), also known as semi-persistent scheduling. Different from allocating radio resources to UE once per TTI during dynamic scheduling (specified by PDCCH), SPS allows semi-static configuration of radio resources, and periodically allocates the resources to a specific UE. [0003] Simply put, the eNodeB uses the PDCCH scrambled by SPS C-RNTI in a certain TTI to specify the radio resource used by the UE, and the UE uses the SPS resource to receive or send data every cycle. The eNodeB does not need to issue a PDCCH in this subframe (that is, the SPS subframe) to specify allocated resources. [0004] Since the SPS has the feature of "one allocation, multiple uses", it is not necessary to deliver DCI (including uplink or ...
