Description

Method, subscriber equipment and evolution base station that measuring reference signals is transmitted
Technical field
The present invention relates to wireless communication technology field, particularly relate to method, subscriber equipment and evolution base station that a kind of measuring reference signals (SRS) is transmitted.
Background technology
Along with the development of the communication technology, Long Term Evolution (LongTermEvolution is called for short LTE) system is used widely.By subscriber equipment (UserEquipment in LTE system, be called for short UE) to enode (EvolvedNodeB, be called for short eNB) send measuring reference signals (SoundingReferenceSignal is called for short SRS), to carry out the measurement of radio uplink channels.
The wireless upstream signals of LTE system is in units of subframe, and the duration of each subframe is 1 millisecond.According to the difference of system, each subframe is divided into 14 or 12 OFDM (OrthogonalFrequencyDivisionMultiplexing, be called for short OFDM symbol) symbol, also referred to as SC-FDMA (singlecarrierfrequencydivisionmultipleaccess) symbol in up, still can think a kind of special OFDM symbol, still be described according to OFDM symbol herein.Wherein provide the structural representation of the subframe be made up of 14 OFDM symbol, each OFDM symbol comprises N number of subcarrier on frequency domain, and the size of N has LTE system band width configuration parameter to determine.ENB is in up running time-frequency resource, and reserved part running time-frequency resource is used for UE and sends SRS to eNB, and concrete reservation mode is as follows:
First eNB sets two parameters: 1) community SRS configuration (cell-specificSRSsubframeconfiguration) parameter; 2) community SRS band width configuration parameter (cell-specificSRSbandwidth) parameter.Above-mentioned two parameters to be sent to the UE in this community by eNB by downlink signaling.In addition, eNB also can issue user's sub-frame configuration (UE-specificSRSsubframeconfiguration) and user SRS band width configuration parameter (UE-specific) parameter, UE according to community SRS configuration parameter and or user's SRS configuration parameter can determine in upward signal, which subframe is for SRS, and namely which subframe is SRS.Last OFDM symbol of SRS, is divided into two comb (comb) by N number of subcarrier of this OFDM symbol of composition, a corresponding odd number subcarrier (1 of comb, 3,5,7,9 ...), the corresponding even number subcarrier (0 of another comb, 2,4,6,8 ...), these two comb are all used for sending SRS transmission.The number of community SRS band width configuration parameter determinant carrier wave is less than or equal to total number of sub carrier wave N of system.As shown in Figure 1, be configured with multiple SRS in upward signal according to some cycles, each SRS is made up of 14 OFDM symbol, and for last OFDM symbol, it is divided into N number of subcarrier according to community SRS band width configuration parameter.Last OFDM symbol of SRS is the running time-frequency resource of SRS, and UE is not at last OFDM symbol transmitting data of SRS; OFDM symbol in SRS except last OFDM symbol all can send the running time-frequency resource of upstream physical layer shared channel (PhysicalUplinkSharedChannel is called for short PUSCH), and UE is uploading data in these OFDM symbol.In other subframes except SRS, all OFDM symbol are the running time-frequency resource that can send PUSCH, and UE is by other sub-frame transmission data above-mentioned.
Along with the development of wireless communication technology, some lower powered eNB are introduced in network, and for doing covering among a small circle, the quantity of the user that each eNB serves reduces with the reduction of scope, and now LTE system will occur unnecessary SRS running time-frequency resource.Because SRS running time-frequency resource exists only in SRS, therefore prior art is by reducing the density of SRS in upward signal, reduces the quantity of SRS, and then reduces SRS running time-frequency resource.As shown in Figure 2, originally configured a SRS in every two subframes, another one subframe is all as the running time-frequency resource of PUSCH, and now by configuring a SRS in every four subframes, its excess-three sub-frame is all as the running time-frequency resource of PUSCH.If have 8 subframes in the upward signal cycle, be then originally configured with 4 SRS altogether.After prior art is optimized, be configured with 2 SRS altogether, reach the running time-frequency resource reducing SRS and take.
State in realization in the process of SRS transmission, inventor finds that in prior art, at least there are the following problems: although prior art can reduce the running time-frequency resource that SRS takies, but SRS density also will decrease, make the transmission cycle of SRS elongated, reduce channel measurement efficiency.
