Description
Technical field
The present invention relates to wireless communication technology, particularly the transmission instruction of a kind of cycle SRS (Sounding ReferenceSignal, detection reference signal) and transmission method, equipment.
Background technology
In existing LTE (Long Term Evolution, Long Term Evolution) system, the detection of up channel completes by sounding (detection) signal.Send sounding signal by terminal at last symbol of SRS subframe, base station can obtain up channel information, thereby carries out the scheduling of resource of uplink and the measurement of various transformation parameters.SRS in LTE system periodically sends, and terminal can continue to send sounding signal with certain cycle, until enter the state without transfer of data.Meanwhile, although terminal has two antennas in LTE system, can only send sounding signal from an antenna simultaneously.If allow UE (User Equipment, subscriber equipment) to carry out transmitting antenna selection, cycle SRS alternately sends from two transmitting antennas.Periodically the transformation parameter of SRS all configures by high level, comprises CS (Cycle Shift, cyclic shift), bandwidth, frequency parameter, cycle and the transmission subframe position etc. of SRS.
Because dispatching cycle is longer, dispatching efficiency is lower, and periodically SRS often will take more physical resource.Particularly, in LTE-A (Long Term Evolution-Advanced, long-term evolution upgrading) system, UE often need to send the SRS of many antennas simultaneously, and resource overhead is larger.In order to improve SRS resource utilization, reduce the expense of SRS resource, in LTE-A system, introduce aperiodic SRS transmission.SRS is different with periodicity, and aperiodic, SRS was base station dynamically active, once terminal only can send disposable sounding signal after activating, and periodic transmitted signal not.By aperiodic sounding, base station can obtain the channel information needing more flexibly, closes or reduces the periodically transmission of SRS, thereby reduce the physical resource expense of SRS signal in the time of conditions permit.Aperiodic, the triggering of SRS was indicated by the corresponding signaling of PDCCH (physical downlink control channel, Physical Downlink Control Channel), and transmission means is indicated by high-level signaling or PDCCH signaling.
LTE-A system is supported this two kinds of SRS transmission simultaneously, and wherein the cycle SRS in the relative LTE system of periodicity SRS also needs to do enhancing to a certain degree.First, now UE at most can be from four antennas transmitted signal, need extra mechanism to support the switching between four antennas.Secondly,, because UE supports multiple antennas transmitted signal simultaneously, can introduce the cycle SRS transmission means of multiport.Now UE need to support single port (or single antenna) and two kinds of SRS transmission meanss of multiport, and base station also needs extra Signalling Designing to indicate the transmission means of UE.
The deficiencies in the prior art are:
The collocation method of existing LTE system can not be supported the periodicity SRS transmission means strengthening in LTE-A system.
