Problems solved by technology

To a certain extent, semi-persistent scheduling is inflexible or wireless resources are wasted, and sometimes dynamic scheduling has to be used to compensate, wasting PDCCH resources
In LTE-Advanced system carrier aggregation technology, there is no solution for semi-persistent scheduling

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] The technical solution of the present invention provides a carrier-specific (Componentcarrier specific) semi-persistent scheduling method in carrier aggregation technology, including: configuring multiple component carriers for semi-persistent scheduling; configuring semi-persistent scheduling parameters for the multiple component carriers ; Activate and allocate semi-persistent resources for the multiple component carriers, and semi-persistent scheduling is performed on the configured multiple component carriers in turn.

[0036] Wherein, configuring multiple component carriers for semi-persistent scheduling specifically includes:

[0037] Multiple component carriers are configured for semi-persistent scheduling through RRC signaling, and identification information of the component carriers is included in the RRC signaling. ...

Abstract

The invention provides a semi-persistent scheduling method, comprising the following steps: configuring a plurality of component carriers for semi-persistent scheduling, configuring semi-persistent scheduling parameters for the component carriers, activating and distributing semi-persistent resources for the component carriers and carrying out semi-persistent scheduling in the component carriers in turn. The invention also provides a semi-persistent scheduling system. The invention carries out semi-persistent scheduling on the carriers in turn, which means that the cycle of semi-persistent scheduling is extended on each component carrier, and not only allows more HARQ times but also obtains certain frequency diversity gain.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-carrier semi-persistent scheduling method and system. Background technique [0002] The Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN) of the third-generation mobile communication Long Term Evolution (referred to as LTE) system is composed of base stations eNB, so it can also be called The radio interface Media Access Control (MAC) protocol layer of the base station eNB)" has a scheduling / priority handling (Scheduling / Priority handling) functional entity, wherein the scheduling function supports dynamic scheduling (Dynamic scheduling) and Semi-persistent scheduling (or semi-persistent scheduling) (Semi-persistent Scheduling). [0003] Dynamic scheduling (Dynamic Scheduling) means that the E-UTRAN can use the Cell Radio Network Temporary Identifier (C-RNTI for short) on the Physical Downlink...
