Description

Downlink control information transmission method and related device

A kind of downlink control information transmission method and relevant device

Technical field

The present invention relates to the communications field, more particularly to a kind of downlink control information transmission method and relevant device.Background technology

In the prior art, the information that base station is sent to UE can be bearing downlink control information（DCI, Downlink Control Information)（It is enhanced）Physical Downlink Control Channel ((E) PDCCH, (Enhanced) Physical Downlink Control Channel).（E) resource that PDCCH is mapped in is by several control channel elements（（E) CCE, (enhanced) Control Channel Element) composition.The quantity for carrying PDCCH CCE is defined as aggregation level.The corresponding search spaces of one aggregation level L are made up of one or more PDCCH candidates, and each PDCCH candidates are corresponding with L control channel element.

Same PDCCH can use a PDCCH candidate in an aggregation level multiple PDCCH candidates corresponding with the aggregation level in multiple aggregation levels.In addition, for different UE, even if the PDCCH candidate indexs used are identical, actual use CCE resources may be differed also.

Search space is divided into public search space again（CSS, Common Search Space) and the proprietary search spaces of UE（USS,UE-specific Search Space ).CSS is made up of the corresponding search space of one or more aggregation levels.USS is also made up of the corresponding search space of one or more aggregation levels.The PDCCH of PDCCH candidate transports in CSS is used for the Physical Downlink Shared Channel (PDSCH for dispatching carrying public message, Physical Downlink Shared Channel) message, such as system message or accidental access response message or beep-page message；And the PDCCH of the PDCCH candidate transports in USS is used for the PDSCH message for dispatching carrying UE proprietary datas.

The collection for defining the corresponding CCE of all PDCCH candidates in CSS is combined into CSS resources, and the collection for defining the corresponding CCE of all PDCCH candidates in USS is combined into USS resources.According to existing protocol, the corresponding CCE of a PDCCH candidate in USS may belong to CSS resources simultaneously, that is, have the overlapping of resource.If for particular UE, the corresponding CCE of specific PDCCH candidates in specific sub-frame in USS belongs to CSS resources, and the CCE is not used for PDCCH of the carrying using any PDCCH candidates in CSS, So, specific PDCCH candidates correspondence CCE, it is possible to for carrying the PDCCH using the PDCCH candidates in USS.Traditional UE can be obtained by blind check PDCCH, that the specific CCE in CSS resources is carried is the PDCCH for using PDCCH candidates in CSS, namely, dispatch the PDCCH of public message, or use the PDCCH of PDCCH candidates in USS, that is, the PDCCH of scheduling UE proprietary datas, and complete being properly received for PDCCH.

But under coverage enhancement scene, in the implementation process that information is repeated, UE needs to merge reception to the information transmitted in multiple subframes.If UE is still through blind check PDCCH candidates, that determine the carryings of the specific CCE in CSS resources is the PDCCH for dispatching public message, or dispatches the PDCCH of UE proprietary datas, and this will greatly increase UE blind Detectings PDCCH complexity.Reason is, for the UE, if some corresponding CCE of PDCCH candidates in USS falls within CSS resources simultaneously, so, the UE can not determine whether the CSS resources carry the PDCCH of scheduling public message, also it can not just determine whether the CCE can be used in the PDCCH that the proprietary data of the UE is dispatched in carrying, whether also can not just determine the PDCCH of the PDCCH candidate transports of the USS in the subframe can participate in the merging reception of information.UE is accomplished by attempting various possible combinations.And the number of times that signal is repeated is more, these repeat have that above-mentioned uncertain subframe is more in transmitting, and the process that UE receives PDCCH is also more complicated, cause UE receive PDCCH efficiency it is more low.The content of the invention
