As we all know, the configuration information of the uplink and downlink subframes is determined by the network equipment according to the uplink and downlink services of the cells in its coverage area. Since the service conditions of different cells are different, it is likely that the uplink and downlink subframe configurations of adjacent cells are different, that is, It is said that for the uplink transmission of a certain cell, sometimes there is interference caused by the uplink signal sent by the UE in the adjacent cell, and sometimes there is interference caused by the downlink signal sent by the network equipment corresponding to the adjacent cell, which may It will lead to: UE and network equipment will be interfered by uplink signal when transmitting RS, but it will be interfered by downlink signal when transmitting data signal with network equipment, that is, the interference information obtained by measuring RS is different from the interference received by transmitted data signal , that is to say, the adjustment plan made is still not accurate enough, which still cannot solve the problem of interference fluctuations

The invention discloses an interference measuring reference signal transmission method and equipment, relates to communication, and relieves the problem of interference wave. The embodiment particularly includes: user equipment UE receive network devices send information transmission time; UE described according to the above information to determine the target during transport time, Network devices described described UE receive send scheduling signaling; UE described according to the stated goals described and scheduling signaling transmission time, and described the network equipment to reference signal transmission, the RS data signal transmission. The present invention is used for interference in the process of the measurement of reference signal transmission.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for transmitting an interference measurement reference signal. Background technique [0002] The network device sends scheduling signaling to user equipment (User Equipment, UE) to instruct the UE to send uplink data signals or receive downlink data signals according to the scheduling signaling. As we all know, the scheduling signaling is determined by the network equipment. In order to make reasonable scheduling, the network equipment needs to measure the channel status in advance. Specifically, for example, when the UE needs to send an uplink data signal to the network equipment, the UE first sends the The network device sends a sounding reference signal (Sounding Reference Signal, SRS), the network device measures the received SRS to obtain uplink channel state information (Channel State Information, CSI), and then determines the scheduling signaling ac...
