In addition, the communication system 100 can be beehive net D-TDD, (Dynamic time division duplex is moved State time division duplex) system or het-net (heterogenous-network, heterogeneous network) group network system or full duplex group Net system.Fig. 2 is the rough schematic view illustrated, and can also include other network equipments in network, not drawn in Fig. 2.

In the embodiment of the present invention, physical channel (physical channel) is specifically used for data information and/or control letter The transmission of breath, for example, physical channel includes following one or combination: PUSCH (physical uplink shared Channel, PUSCH, Physical Uplink Shared Channel), and PUCCH (physical uplink control channel, physically Row control channel), PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel), EPDCCH (Enhanced-Physical Downlink Control Channel, the Physical Downlink Control Channel of enhancing), PCFICH (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel), PHICH (Physical hybrid ARQ indicator channel, physical mixing retransmission indicating chanel), PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) etc. or standard in the function that newly introduces it is identical, but name Claim the control channel introduced in different channels, such as short TTI transmission or data channel etc..

It should be understood that in the embodiment of the present invention, " when ... ", " if " and " if " refer both to the terminal under certain objective circumstances Equipment or access network equipment can make corresponding processing, be not limiting time, and also not require terminal device or access net Equipment has to the movement of judgement when realizing, also do not mean that there are other restrictions.

In wireless communication system specific scheduling flow be UE receive base station send control channel (such as PDCCH or its His control channel), which can carry the biography in data channel (such as PDSCH or PUSCH or other data channels) Defeated piece of scheduling information, the scheduling information include the resource allocation information for such as carrying the data channel of transmission block, modulating-coding Mode etc. controls information.UE carries out the reception of data channel according to the above-mentioned control information carried in the control channel detected Or it sends.

Due to the demand that network side and terminal side uplink and downlink switch, the timing advance of the timing meeting versus downstream frame of uplink frame T_ATime.As being expressed as T in Fig. 3_A=N_TAT_s.The timing adjustment parameter N that base station will need UE to adjust_TAValue or N_TARemoval is fixed inclined Value after shifting notifies to calculate the time parameter T actually adjusted according to this to UE, UE_A.Here N_TAOr its transformed value is the hair of UE Send timing adjustment parameter.T_sFor predefined chronomere.

To reduce the cross link interference in wireless system, need to measure the interference between UE-UE in system.Than Such as, it can be the measuring signal that a UE sends one or more symbols in uplink frame (uplink frame), another UE exists Downlink frame (downlink frame) measures it.It is directly fixed using uplink due to being misaligned for above-mentioned uplink and downlink timing When the measurement symbol that sends have biggish dislocation when reaching the position of another UE downlink reception, that is to say, that UE directly exists at this time Downlink symbol position, which carries out UE-UE interference measurement to measuring signal, will cause relatively large deviation.

Such as in Fig. 4, the sequential relationship of the UE2 timing measured and measuring signal transmitting UE1 is set forth.UE2 Measurement timing be UE2 receive downlink signal or carry out downlink measurement timing.The uplink timing of UE1 is that UE1 is adjusted using timing After whole parameter, the timing of uplink transmission is carried out, UE-UE measuring signal use here sends identical timing parameters with uplink.It is false If UE1 emits out-hole run signal in uplink symbol 3 (by taking measuring signal is SRS symbol as an example).Due to the timing of uplink and downlink The influence of deviation and propagation delay, UE1 is when the SRS of uplink symbol 3 emitted reaches UE2 in figure, the symbol of measuring signal It is the position of UE2 downlink measurement symbol 2-3, character position as shown in dotted outline in FIG. that boundary is corresponding.

In this case, the deviation size of the received SRS symbol of UE2 and measurement Symbol Timing depends on UE uplink timing tune The size of whole amount.Such as the uplink timing adjustment for using 20us in NR, the system for using 15k subcarrier parameter, Symbol deviation is about 0.28 symbol；System for using 30k subcarrier parameter, symbol deviation are about 0.56 symbol.These values All considerably beyond CP (cyclic prefix, cyclic prefix) length (CP representative value is 0.07 symbol lengths), UE2 is caused to accord with Numbers 2 or symbol 3 carry out the measurement of UE-UE and can all generate biggish measurement error.

According to an embodiment of the invention, a kind of feasible solution is exactly to carry out the adjustment of SRS transmission timing parameter, make SRS signal adjusted when reaching measurement end, the timing offset with downlink measurement symbol within the CP of downlink measurement symbol, To obtain more accurate measurement result.

As shown in figure 5, UE1 carries out SRS transmission using timing parameters adjusted, when so that signal reaching UE2, with UE2 The deviation of symbol is measured within CP, to obtain accurate measurement.Under this scheme, the measurement error of UE-UE is avoided, but meeting Bring other problem.As shown in fig. 6, UE1 is sent on the character position of the signal of SRS, other UE may send PUSCH.Than UE3 in such as figure possible configuration uplink PUSCH transmission on the position of symbol 0-5.Uplink meeting of the UE3 on symbol 3 or 4 Interference is generated to the SRS that UE1 is sent, to influence the measurement of UE-UE interference.

According to an embodiment of the invention, another feasible method for solving measured deviation is measuring signal use and PUSCH Identical uplink timing adjustment parameter, at the same by adjusting downlink measurement symbol come realize timing offset correct.Such as Fig. 7 institute Show.At this moment the downlink measurement timing that adjustment can be used in UE2 carries out UE-UE measurement.Downlink measurement symbol and SRS adjusted are surveyed The timing offset of signal is measured within the scope of CP.To avoid interfering, UE2 and other downlinks UE with cell need the symbol to influence Number position (being 2,3 symbols in figure) is identified, in these character positions without downlink reception.

Therefore, (physical downlink shared channel, downlink are shared by UE transmission PUSCH or reception PDSCH Physical channel) when, the interference in order to avoid data-signal to measuring signal can be dry to that may generate to UE-UE measuring signal The symbol disturbed carries out rate-matching (rate-matched) or muting (mute).UE needs to be determined according to the parameter of configuration Rate-matching (rate-matched) or muting (mute) is on which symbol.Rate-matching (rate is done to symbol Matching) or muting (mute), refer to before encoding or remove the corresponding resource of symbol from available resources after coding, i.e., Do not have in the corresponding some frequency domain resources of the symbol of rate-matching (rate-matched) or muting (mute) signal emit or It receives.

The present embodiments relate to network element include the network equipment and terminal device.The network equipment is joined to terminal equipment configuration Number, terminal device carry out rate-matching or muting to partial symbols and handle.In one embodiment, terminal device according to The measurement resource and timing adjustment amount binding signal of configuration send the SCS where BWP (Bandwidth part, portions of bandwidth) Parameter determines the running time-frequency resource for needing ratematching or puntched, avoids the interference to measuring signal.

The time domain that the time domain width of OFDM symbol is determined by SCS (sub carrier spacing, subcarrier spacing) parameter The sum of width and the CP width of addition determine.SCS parameter determines that the time domain width for being not added with the symbol of CP, such as 15k carry The symbol time domain width of wave is 1/15ms, and the symbol time domain width of 30k subcarrier is 1/30ms.The width of CP in NR there are two types of Situation, normal CP and extended CP, their CP length are different.

The symbol time domain width of different SCS is different, therefore identical timing adjustment amount is right under different SCS configurations Symbol in requisition for the PUSCH/PDSCH of adjustment is different.Than as shown in figure 8, two systems use identical Δ T timing adjustment Amount.Using in the system of SCS2, due to the half that symbol intervals are SCS1, the corresponding data symbol serial number 4 of SRS character position With 5, and use corresponding data symbol serial number 3 and 4 in the system of SCS1.Therefore, UE needs to be determined according to configuration parameter Need to do the character position of rate-matching or muting, configuration parameter includes the character position of measuring signal, timing adjustment Value and the SCS parameter of place BWP etc..

In the embodiment of the present invention, it is illustrated so that measuring signal is SRS as an example, other measuring signals is also suitable.
