Description

It is used for transmission method, base station and the user equipment of reference signal

Technical field

The present embodiments relate to the communications fields, and more particularly, to method, the base station for being used for transmission reference signal And user equipment.

Background technique

For the user's perception for promoting Cell Edge User equipment, senior long term evolution (Long Term Evolution Advanced, referred to as " LTE-A ") system use cooperative multi-point (Coordinated Multiple Point, referred to as " CoMP ") technology.At present for the user equipment of support CoMP, serving BS is that the user device configuration covers under physics more first Row shared channel resources map colocation site (Physical Downlink Shared Channel Resource Element Mapping and Quasi-Co-Location, referred to as " PQ ") parameter, wherein every set PQ parameter may include cell-specific Reference signal (Cell-specific Reference Signal, referred to as " CRS ") and channel state information reference signals The resource configuration parameter of (Channel State Information Reference Signal, referred to as " CSI-RS ").When It, can be in the descending control signaling sent to the user equipment when the serving BS carries out actual schedule to the user equipment Increase by 2 bits in (Downlink control information, referred to as " DCI ") to indicate the user equipment using above-mentioned Which set PQ parameter in more set PQ parameters carries out signaling and data transmission, which can carry out rate according to the instruction Match, to determine for carrying out data transmission, then which resource unit (Resource Element, referred to as " RE ") is The user equipment can demodulate the data on these RE, and receive CRS and CSI-RS according to the instruction, to estimate corresponding timing Deviation and frequency departure, and time-frequency domain correction is carried out to received data.

In order to further enhance the effective rate of utilization of frequency spectrum, researcher proposes new carrier type (New Carrier Type, referred to as " NCT ") carrier wave, and carry in NCT carrier wave the new reference signal for time-frequency tracking, this is new Time-frequency track reference signal is different from CRS, demodulated reference signal (Demodulation in existing normal carrier wave Reference Signal, referred to as " DMRS ") and CSI-RS, and the running time-frequency resource that the time-frequency track reference signal occupies is lower than The running time-frequency resource that CRS in existing normal carrier wave is occupied.Therefore, under CoMP scene, if one or more transfer points make With NCT carrier wave, and user equipment has no idea to know the time-frequency tracking ginseng transmitted on the NCT carrier wave of the transfer point of current service The running time-frequency resource configuration information of signal is examined, for example, the period of time-frequency track reference signal, sub-frame offset and time-frequency track reference letter The RE's of number occupancy in the position and time-frequency track reference signal of frequency domain in 1 RB of RB number, these RB occupied Position and number etc., the user equipment cannot carry out rate-matched and correctly demodulate downlink data, influence the proper solution of data Reconciliation user experience.

Enhance Inter-Cell Interference Coordination (Further enhanced Inter-Cell Interference Coordination, referred to as " FeICIC ") it is also that the one kind for promoting cell throughput in heterogeneous network (Hetnet) has efficacious prescriptions Method, base station can be by the CRS configuration notification user equipmenies of interfered cell, Physical Cell Identifier, antenna port and multicast including CRS Unicast single frequency network (Multiple-cast Broadcast over Single Frequency Network, referred to as " MBSFN ") configuration parameter, user equipment using these acquisition of information arrive interfered cell CRS information, can carry out interfere disappear Except (Interference Cancelling, referred to as " IC ") receiver algorithm, the interfered cell on the position CRS is calculated Signal, and it is deleted from the signal received, achieve the purpose that promote UE demodulation performance.In following wireless communication system In, if interfered cell has used NCT carrier wave, and user equipment has no idea to know on NCT carrier wave that the interfered cell uses Time-frequency tracks the running time-frequency resource configuration information of pilot tone, cannot track pilot tone to the time-frequency of interfered cell and use IC receiver algorithm Interference elimination is carried out, the performance and user experience of system are influenced.
