It should be noted that, the embodiment of the present invention is illustrated by taking first network equipment and second network equipment as an example, but, the embodiment of the present invention can apply to the situation of the only one of which network equipment, such as there was only the situation of first network equipment, in this case, the first module and the second module in the network equipment do corresponding processing, with reference to the description of the embodiment of the present invention.In order to save About length, is subsequently repeated no more.

In above-described embodiment, described first network equipment is responsible for user equipment（User Equipment, cylinder claim UE) configuration Physical Downlink Control Channel set first group of resource collection equipment, it is also likely to be the equipment for being responsible for transmitting downlink data to UE simultaneously, but not responsible it can also transmit downlink data to UE, base station 0 or base station 1 e.g. shown in Fig. 1, but the first network equipment can also be the other kinds of network equipment outside base station in specific implementation.First group of resource collection includes the resource of the corresponding Physical Downlink Control Channel set of downlink data just passed.

Wherein, this step can be by taking the information that base station 0 sends first group of resource collection as an example, for example, base station 0 is notified the information of first group of semi-static resource collection to UE by high-level signaling, first group of resource collection is pre-configured with to UE so as to realize.Certainly in specific embodiment or base station 1 transmission etc., in this case, base station 1 are the equipment for being responsible for configuring first group of resource collection of Physical Downlink Control Channel set to UE.

The Physical Downlink Control Channel set includes the Physical Downlink Control Channel that downlink data may be used just passed.

The information of first group of resource collection, can be the information that UE detects the resource collection required for Physical Downlink Control Channel in Physical Downlink Control Channel set.For example, the running time-frequency resource configuration information of first of set, the wherein Physical Downlink Control Channel in Physical Downlink Control Channel set can be Physical Downlink Control Channel（Physical Downlink Control Channel, cylinder claims PDCCH) or enhanced Physical Downlink Control Channel（Enhanced Physical Downlink Control Channel, cylinder claims EPDCCH).One group of resource collection can include one or more resource collection, therefore referred to as one group.The running time-frequency resource that one resource collection can be used comprising one or more of Physical Downlink Control Channel.For example, one or more Physical Resource Block or Physical Resource Block pair may be included corresponding to an EPDCCH resource collection（Physical Resource Block Pair, cylinder claims PRB Pair) ,-individual Physical Resource Block is to including two Physical Resource Block in a subframe.The running time-frequency resource used and/or scrambler of the corresponding Physical Downlink Control Channel of the set can be included in the information of one resource collection.The scrambler of the corresponding Physical Downlink Control Channel of different resource collections is probably different.UE can detect Physical Downlink Control Channel collection according to the information of first group of resource collection Physical Downlink Control Channel in conjunction, to complete receptions of the UE to the corresponding control information of downlink data.

The Physical Downlink Control Channel of re-transmission is the Physical Downlink Control Channel for re-transmission.For example, base station 0 can be notified the information of second group of resource collection to UE by high-level signaling, so UE just can be according to the information of second group of resource collection, the Physical Downlink Control Channel of retransmission detection, for example, detect the Physical Downlink Control Channel of all UE candidate in resource in second group of resource collection being pre-configured with.Certainly in specific embodiment or base station 1 transmission etc..

The information of second group of resource collection can include the running time-frequency resource configuration information for the Physical Downlink Control Channel that correspond to retransmit the downlink data, and wherein Physical Downlink Control Channel can be PDCCH or EPDCCH.UE can for example detect the Physical Downlink Control Channel of the candidate of the UE according to the information of second group of resource collection, the Physical Downlink Control Channel of retransmission detection.In the particular embodiment, second group of resource collection may be embodied in first group of resource collection, i.e. second group resource collection can be the subset of first group of resource collection, can also be that second group of resource collection intersects with first group of resource collection, it can also be that group resource collection of the resource collection separate with first group of resource collection, i.e., second and first group of resource collection are non-intersect.

Optionally, the configuration information of described Physical Uplink Control Channel may also include causing UE to determine to which base station feedback response message or receive the resource information, it is also possible to so that UE determines which base station is responsible for re-transmission.

Optionally, for the Physical Downlink Control Channel at least one described subset, the network equipment is to one group of public reference signal of notification of user equipment（Common Reference Signal, cylinder claims：CRS at least one CRS rate matching information in) rate matching information, one group of CRS rate matching information includes at least two CRS patterns（Pattern) information.

Wherein, one group of described CRS rate matching information has corresponding relation with the Physical Downlink Control Channel set, one group of i.e. described CRS rate matching information correspond to the downlink data that at least one described Physical Downlink Control Channel of UE receptions is indicated, to cause UE completes downlink data to receive.One group of CRS rate matching information may include one or more CRS rate matching information.One CRS rate matching information can indicate one or more CRS pattern-information. One CRS rate matching information of one downstream data channel, can be used for the resource impact of data channel so that the resource unit shared by the CRS patterns of instruction is not used in the resource impact of data channel.When the corresponding one group of CRS rate matching information of the Physical Downlink Control Channel has multiple CRS rate matching informations, it can indicate which CRS rate matching information is used for data channel in Physical Downlink Control Channel, such as be indicated in the mapping of physical down data channel resource list and accurate co-located instruction PQI (PDSCH RE mapping and Quasi-co-location Indicator) bit field in Physical Downlink Control Channel.The downlink data that Physical Downlink Control Channel at least one described subset is indicated uses at least one CRS rate matching information in one group of CRS rate matching information to carry out rate-matched.

It should be noted that described CRS rate matching informations include the CRS information for example for representing CRS patterns；At least one of which CRS rate matching informations of such as one group CRS rate matching information include at least two CRS pattern-informations.Moreover, it is assumed that as shown in Figure 1, base station 0 and base station 1 are common to UE transmission data, then a CRS rate matching information for example can include base station 0 and the two equipment of base station 1 distinguish corresponding CRS information；In another example, if UE receives data failure, it is assumed that need to retransmit data from base station 0 to UE, then a CRS rate matching information can also include the corresponding CRS information in base station 0.

In the information configuring methods of the embodiment of the present invention, by being that second group of resource collection that first group of resource collection for just passing the Physical Downlink Control Channel set used and re-transmission are used is respectively configured in user equipment by first network equipment, UE can be enabled to be detected from the first group of resource collection and second group of resource collection that are pre-configured with and just pass the Physical Downlink Control Channel that the Physical Downlink Control Channel used and re-transmission are used, so to a hybrid automatic repeat-request, (Hybrid Automatic Repeat Request, cylinder claims：HARQ) process UE can just utilize multiple transfer resources being pre-configured with（Including the resource in first group of resource collection and second group of resource collection）Obtain the unity gain of multiple resources.Secondly, first network equipment is that user equipment is pre-configured with first group of resource collection for just passing the Physical Downlink Control Channel set used and retransmits the second group of resource collection used respectively, when reducing acquisition unity gain, UE carries out the complexity of blind Detecting to the Physical Downlink Control Channel of re-transmission.

Alternatively, as shown in Figure 2 a, above-described embodiment one can also comprise the following steps：
