Description

Send synchronizing signal, determine the method and apparatus of carrier type
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of method and apparatus sending synchronizing signal, determine carrier type.
Background technology
At LTE(Long Term Evolution, Long Term Evolution) in the R11 agreement of system and former protocol version, the initial clock that synchronizing signal is used for carrying out between Cell searching and base station is synchronous.Wherein, described synchronizing signal is divided into PSS(Primary Synchronization Signal, master sync signal) and SSS(Secondary Synchronization Signal, auxiliary synchronous signals).In different system types, for sending the resource location information difference (namely frequency domain position is identical, and time-domain position is not identical) of PSS/SSS.
Such as: suppose with conventional CP(Cyclic Prefix, Cyclic Prefix) (conventional CP contains 14 OFDM symbol) be example, be FDD(Frequency Division Duplex at system type, Frequency Division Duplexing (FDD)) time, the time-domain position of PSS is last symbol of first time slot taking subframe 0,5, the time-domain position of SSS is next-door neighbour PSS, take the previous symbol of last symbol of first time slot of subframe 0,5, as shown in Fig. 1 (a), it is the time-domain position structural representation of synchronizing signal in FDD system;
Be TDD(Time Division Duplex at system type, time division duplex) time, the time-domain position of PSS is the 3rd symbol taking subframe 1,6, the time-domain position of SSS is last symbol taking subframe 0,5, as shown in Fig. 1 (b), it is the time-domain position structural representation of synchronizing signal in TDD system.
Simultaneously, in R9 release protocol, R10 release protocol and R11 release protocol, definition is for sending DMRS(Demodulation Reference Signal, demodulated reference signal) resource location in time-domain position be divided into latter two symbol taking each time slot, as shown in Figure 2, be the resource location structural representation for sending DMRS.Comparison diagram 1(a) and Fig. 2, can finding out, in FDD system, conflicting with the time-domain position for sending PSS/SSS for the time-domain position sending DMRS; Comparison diagram 1(b) and Fig. 2, can finding out, in a tdd system, conflicting with the time-domain position for sending SSS for the time-domain position sending DMRS.Once occur conflicting with the time-domain position for sending DMRS for the time-domain position sending PSS/SSS, System Priority sends PSS/SSS, makes DMRS be abandoned sending, will cause the waste of frequency spectrum resource like this, and reduce the efficiency of frequency spectrum resource.
There is the problem of frequency spectrum resource waste in order to solve R11 release protocol and release protocol before, improving spectrum efficiency further, in the R12 release protocol studied, introducing NCT(New Carrier Type, new carrier type).In NCT, many reference signals simplify, such as: CRS(Cell Reference Signal, cell reference signals) only remain a port, CRS after simplification is called as TRS, and the resource location taken reduces, and makes each RB(Resource Block, Resource Block) in available RE quantity increase, the resource location revised for sending PSS/SSS becomes possibility.
Particularly, in a tdd system, for NCP, arranging the 5th symbol taking subframe 1 and 6 is the time-domain position of PSS, and arranging the 2nd symbol taking subframe 1 and 6 is the time-domain position of SSS; For ECP, arranging the 4th symbol taking subframe 1 and 6 is the time-domain position of PSS, and arranging the 1st symbol taking subframe 1 and 6 is the time-domain position of SSS.
Problems existing is: because subframe 1 and 6 is configured to special subframe usually, wherein, special subframe is made up of DwPTS, GP and UpPTS, and when DwPTS only has the TDD special subframe time slot proportion of 3 OFDM symbol, cannot support that configuration the 4/th or 5 symbols are the situation of the time-domain position for transmitting PSS; Simultaneously because time-domain position in the resource location for sending TRS is arranged on the 1st and 5 symbols, causing TRS and PSS/SSS not transmit simultaneously, reducing synchronized tracking precision.
Summary of the invention
