Description
Technical field
The present invention relates to mobile communication technology field, more specifically, relate to carrier transmission method, equipment and the system of carrying Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) information.
Background technology
Along with the development of mobile communication technology, subscriber traffic and data throughout constantly increase, and 3-G (Generation Three mobile communication system) can not meet user's demand completely.Therefore, third generation partner program (3rdGeneration Partnership Project, 3GPP) is devoted to the evolution using 3GPP Long Term Evolution (Long TermEvolution, LTE) as 3G system.In order to obtain higher data rate, lower time delay, improved power system capacity and coverage, in the urgent need to needing the technology of carrier aggregation.
Up to now, in the design of carrier aggregation PDCCH, select (option) 1b scheme to be retained, its core concept is that PDCCH can carry out distributing instruction across carrier resource, for example indicate certain subscriber equipment (User Equipment, UE) the PDCCH information of resource allocation information on carrier wave 1, carrier wave 2 and carrier wave 3, all be placed on carrier wave 2 and transmit, and show the corresponding relation between instruction PDCCH and carrier wave by a carrier wave instruction (CarrierIndicator, CI).Fig. 1 is the PDCCH information carrying schematic diagram across carrier wave in prior art.As seen from Figure 1, transmitted the PDCCH information of instruction UE resource allocation information on carrier wave 1, carrier wave 2 and carrier wave 3 by carrier wave 2, and carrier wave 2 is from a left side to being divided into 3 regions, is respectively used to the resource allocation information of certain UE of carrying instruction on carrier wave 1, carrier wave 2 and carrier wave 3.
