In embodiments of the present invention, transmission unit can represent but be not limited to represent time quantum, and time quantum can be with The time-domain resource of transmission signal is represented, they can continue to use existing radio frames or frame, subframe, time slot, Transmission Time Interval (Transmission Time Interval, TTI), the title or implication of the term such as OFDM symbol, can also be represented in future Implication in communication system.In addition, the present invention does not limit the title of these terms, that is to say, that these terms are logical in future In letter system, the title in future communication systems can be used.
By taking subframe as an example, in future communication systems, the implication of subframe may change.For example, subframe does not limit 1ms, it is possible to can be other subframe lengths, it is also possible to can be a dynamic subframe lengths, the time span of subframe can be with With the different and different of subcarrier spacing.The title of subframe is it can also happen that change, if the title of subframe changes, then can So that the subframe in the embodiment of the present invention to be transformed to the respective name in future communication systems.In description herein, in order to Succinctly, illustrated by taking statement general at present as an example.
Fig. 4 shows the indicative flowchart of the method for transmission signal according to an embodiment of the invention.In Fig. 4 TRP can be the TRP in the TRP 101-105 in Fig. 1；Terminal device can be the terminal device 111 in Fig. 1.Certainly, it is actual In system, the quantity of TRP and terminal device can be not limited to the citing of the present embodiment or other embodiment, repeat no more.
410, TRP produce the first signals, wherein, first signal includes N number of signal sequence, in N number of signal sequence extremely Rare two signal sequence differences, N are positive integer more than or equal to 2, first signal be used for terminal device only according to this One signal carries out time synchronized.
In embodiments of the present invention, at least two signal sequence differences in multiple signal sequences that the first signal includes, Different from the existing PSS using identical signal sequence, so, terminal device can pass through the different letters of the first signal of detection Number sequence realizes time synchronized, such as slot timing, frame timing or transmission unit timing.
Alternatively, N 2, N number of signal sequence are the first signal sequence and secondary signal sequence, first signal sequence It is conjugated each other with the secondary signal sequence.That is, in this case, the first signal includes two signals being conjugated each other Sequence, i.e. the first signal sequence and secondary signal sequence.
In the case where the first signal is using two signal sequences being conjugated each other, receiver is fairly simple, it is only necessary to uses One known array carries out related can detection to the synchronizing signal received, it is not necessary to is docked respectively with two known arrays The synchronizing signal received carries out correlation to detect.
Specifically, first signal can use Zadoff-Chu (ZC) sequence, i.e. N number of signal sequence is ZC sequences. Alternatively, first signal sequence and the secondary signal sequence can be the ZC sequences being conjugated each other.
For example, the sequence for first signal can generate according to below equation (1)：
Wherein, u is the radical exponent of ZC sequences.U can be positive integer, or negative integer.Include in the first signal N number of It u corresponding to N number of signal sequence, can all be positive integer during signal sequence, can also all be negative integer.Alternatively, choosing is passed through Two different radical exponent u are selected, the first signal sequence and secondary signal sequence can be obtained, further can be special by selecting Two different radical exponent u, two the first signal sequences being conjugated each other and secondary signal sequence can be obtained.For example, the The radical exponent u of one signal sequence1Can be 29, the radical exponent u of secondary signal sequence2Can be 34.
420, TRP send first signal.
Terminal device has corresponding reception to act, and in embodiments herein, the reception action at correspondingly received end belongs to The scope of the present invention, no longer repeat one by one.
Specifically, N number of signal sequence of the first signal is sent in different N number of time quantums, and different N number of time is single One or more predetermined bias values are spaced between member, i.e., each signal sequence is sent in a time quantum, between time quantum between Every one or more predetermined bias values.For example, in the case where N is 2,2 signals are sent in 2 time quantums respectively, and this 2 One or more predetermined bias values are spaced between individual time quantum.
Alternatively, when the first signal includes the first signal sequence and secondary signal sequence, TRP can be in very first time unit Interior transmission first signal sequence, sends the secondary signal sequence in the second time quantum, the very first time unit with this Two time quantum interval one or more predetermined bias values.
In embodiments of the present invention, time quantum represents the one continuous time in time domain.For example, time quantum can be with For subframe, but the present invention is not limited this.
Send second time quantum interval one of the very first time unit of the first signal sequence with sending secondary signal sequence Individual or multiple predetermined bias values, such terminal device can realize time synchronized by the detection to two signal sequences.
For example, when two signal sequences of the first signal are sent in a radio frames, can be real by first signal Existing frame synchronization.
For example, TRP sends first signal sequence in the first subframe of radio frames, in the second subframe of the radio frames The secondary signal sequence is sent, first subframe and half of radio frames of the second sub-frame interval.That is, by the first signal sequence It is listed in the first subframe and sends, secondary signal sequence is sent in the second subframe, so, terminal device can be made to identify field Timing and frame timing.
Alternatively, first subframe is 0 work song frame of the radio frames, and second subframe is 5 work song frames of the radio frames.
Specifically, the first signal sequence is sent on 0 work song frame, secondary signal sequence is sent on 5 work song frames.
