If the user equipment is configured with transmission mode 8-10, it can be assumed that the DMRS antenna port of the serving cell in one subframe (time extension, Doppler spread, Doppler shift, average gain, average spread) is quasi-common Address.

 For example, for ease l , the first resource mapping mode or the third resource mapping mode is adopted.

For case 2, if the CRS of the serving cell corresponding to the PDSCH is the same or quasi-co-located as the CRS in the PQI information configured for the EPDCCH, the first resource mapping mode or the third resource mapping mode is adopted; if the CRS of the serving cell corresponding to the PDSCH The second resource mapping mode is adopted, or the CSI-RS of the serving cell corresponding to the PDSCH and the CSI-in the PQI information configured for the EPDCCH are used. If the RS is the same or quasi-co-located, the first resource mapping mode or the third resource mapping mode is adopted; for example, the PDSCH corresponds to If the CSI-RS of the monthly service cell is different from the CSI-RS in the PQI information configured for the EPDCCH or is not co-located, the second resource mapping mode is adopted; or if the CRS of the serving cell corresponding to the PDSCH is configured for the EPDCCH If the CSI-RS in the PQI information is the same or quasi-co-located, the first resource mapping mode or the third resource mapping mode is adopted; if the CRS of the serving cell corresponding to the PDSCH is different from the CSI-RS in the PQI information configured for the EPDCCH.

^M scm = ² liters and "ID through the high-level configuration, "ι. , 1 in '· represents the number of the EPDCCH PRB set. The setting of the resource mapping rule by the base station according to the initialization parameters of the DMRS pilot of the EPDCCH and the PDSCH may be: if the pilot initialization parameter of the EPDCCH is configured, and the pilot initialization parameter of the PDSCH is the same as the ^MRS , the first resource mapping manner is adopted. The third resource mapping mode is adopted. If the pilot initialization parameter of the EPDCCH configuration is different from the pilot initialization parameter of the PDSCH= ^η ^′′, the second resource mapping mode is adopted.

 It should be noted that, in the foregoing process, due to the pilot sequence initialization parameter of the EPDCCH

When the pilot sequence initialization parameters of the PDSCH are different, the PDSCH and the EPDCCH are from different transmitting nodes, so the PDSCH and the EPDCCH can adopt the second resource mapping manner; similarly, when the pilot sequence of the EPDCCH is initialized _; When the pilot sequence initialization parameter of the PDSCH is the same, it indicates that the PDSCH and the EPDCCH are the same transmitting node, so the PDSCH and the EPDCCH may adopt the first resource mapping manner or the third resource mapping manner.

 Optionally, the resource mapping rule may be set according to an aggregation level of the EPDCCH. For example, when the aggregation level of the EPDCCH is greater than the preset value, the first resource mapping manner is adopted, and the third resource mapping manner is adopted. When the aggregation level of the EPDCCH is not greater than the preset value, the second resource mapping manner is used.

It should be noted that, in the foregoing process, when the aggregation level of the EPDCCH is not greater than the preset value, indicating that the channel condition is good, the PDSCH and the EPDCCH may adopt the second resource mapping manner. Similarly, when the aggregation level of the EPDCCH is greater than the preset. The value indicates that the channel condition is not good, so the PDSCH and the EPDCCH may adopt the first resource mapping manner or the third resource mapping manner. Optionally, the resource mapping rule may be set according to a scheduling format of the control channel. For example, when the scheduling format of the PDSCH is the space frequency code SFBC, the first resource mapping mode adopts the third resource mapping mode; when the scheduling format of the PDSCH is beamforming beam forming or spatial multiplexing, the second resource mapping is adopted. the way.

 It should be noted that, in the foregoing process, when the scheduling format of the EPDCCH is beamforming or spatial multiplexing, indicating that the channel condition is good or the base station can obtain accurate precoding information, the PDSCH and the EPDCCH may adopt the second. In the resource mapping mode, the user equipment solves the resource mapping according to the solution mapping manner corresponding to the second resource mapping manner. Similarly, when the scheduling format of the EPDCCH is the space frequency code SFBC, the channel condition is not good or the base station cannot know the accurate precoding. Information, so the PDSCH and the EPDCCH may be in a first resource mapping manner or a third resource mapping manner, and the user equipment may perform resource mapping according to the corresponding solution resource mapping manner.

 Optionally, the resource mapping rule can be set according to the PQI state. For example, when the PQI state is "00", the second resource mapping mode is adopted.

 It should be noted that when the base station determines the mode of adopting the resource mapping by using the PQI state, the aggregation level of the EPDCCH, or the scheduling mode of the PDSCH, the PQI state and the aggregation level of the EPDCCH may be dynamically signaled before the user equipment determines the resource mapping mode. Or the PDSCH scheduling format notifies the user equipment.

Optionally, in a scenario where the EPDCCH and the PDSCH signal can be scheduled across carriers, the resource mapping rule may be set according to whether the EPDCCH performs cross-carrier scheduling. For example, as shown in FIG. 7, for the PDSCH on the EPDCCH1 scheduling carrier CC1 transmitted on the carrier CC0, the EPDCCH2 transmitted on the carrier CC0 schedules the PDSCH on the carrier CC2. The base station may set the resource mapping rule according to the initialization parameters of the DMRS pilot of the EPDCCH and the PDSCH. The PDSCH on the CC0 may not be mapped to the physical resource block occupied by the EPDCCH0, the EPDCCH 1, and the EPDCCH 2 (the first resource mapping mode or the third resource). The PDSCH on the CC0 may not be mapped to the physical resource block occupied by the EPDCCH0 (the first resource mapping mode or the third resource mapping mode), but may be mapped to the physical resource blocks occupied by the EPDCCH1 and the EPDCCH2. (second resource mapping mode); or, the base station is free to decide whether it can be mapped to EPDCCH0, EPDCCH 1 and The manner in which the user equipment resource mapping is indicated by the dynamic signaling or the high layer signaling on the physical resource block occupied by the EPDCCH 2.

 It should be noted that the method in the embodiment of the present invention may also be used to transmit a PDSCH signal and a CRS signal between a base station and a user equipment.

 Optionally, when the configuration information of the CRS includes at least two CRSs, the base station may further perform resource mapping on the PDSCH and/or the CRS according to the first resource mapping manner or the third resource mapping manner, where the CRS configuration information is that the base station can pass The high layer signaling is sent to the user equipment.

 It should be noted that, in the foregoing different resource mapping rules, the data processing procedure of the base station and the user equipment is the same as the data processing procedure in the embodiment of the present invention, and details are not described herein again.

 It should be noted that, in the embodiment of the present invention, the signal transmission by the base station to the user equipment is taken as an example, and the method of the embodiment of the present invention may also be used for signal transmission between other network devices, which is not limited herein.

 In the prior art, the PDSCH does not perform resource mapping on the resource block on which the EPDCCH data is mapped, and the resource utilization rate is low. In the embodiment of the present invention, the base station according to the EPDCCH and the PDSCH quasi co-location type and resource mapping rule. Determining a resource mapping manner in the at least two candidate resource mapping manners, performing resource mapping on the EPDCCH and the PDSCH in the same physical resource block, and then transmitting the signal to the user equipment; after receiving the signal transmitted by the base station, the user equipment receives the signal transmitted by the base station. The resource mapping manner is determined in the at least two candidate resource mapping manners by using the quasi-co-location type and the resource mapping rule of the EPDCCH and the PDSCH to perform the solution mapping. In this manner, when the PDSCH and the EPDCCH are resource mapped in the same physical resource block, the base station and the user equipment can determine the resource mapping manner from the candidate resource mapping manner according to specific channel conditions and scheduling conditions, perform resource mapping and resource mapping, and make full use of the resource mapping manner.
