Description

The method and apparatus for send synchronizing signal, determining carrier type
Technical field
The present invention relates to wireless communication field, more particularly to a kind of method for sending synchronizing signal, determining carrier type and Equipment.
Background technology
In LTE（Long Term Evolution, Long Term Evolution）In the R11 agreements of system and pervious protocol version, The initial clock that synchronizing signal is used for carrying out between cell searching and base station is synchronous.Wherein, the synchronizing signal is divided into PSS （Primary Synchronization Signal, master sync signal）And SSS（Secondary Synchronization Signal, auxiliary synchronous signals）.In different system types, the resource location information for sending PSS/SSS is different（That is frequency Domain position is identical, and time-domain position differs）.
Such as：Assuming that with conventional CP（Cyclic Prefix, cyclic prefix）（Conventional CP contains 14 OFDM symbols）For Example, is FDD in system type（Frequency Division Duplex, frequency division duplex）When, the time-domain position of PSS is to take The last symbol of first time slot of subframe 0,5, the time-domain position of SSS are close to PSS, take first of subframe 0,5 The previous symbol of the last symbol of time slot, such as Fig. 1（a）It is shown, it is the time-domain position structure of synchronizing signal in FDD system Schematic diagram；
It is TDD in system type（Time Division Duplex, time division duplex）When, the time-domain position of PSS is to take 3rd symbol of subframe 1,6, the time-domain position of SSS are the last symbols for taking subframe 0,5, such as Fig. 1（b）It is shown, be The time-domain position structure diagram of synchronizing signal in TDD system.
Meanwhile in R9 release protocols, R10 release protocols and R11 release protocols, definition is used to send DMRS （Demodulation Reference Signal, demodulated reference signal）Resource location in time-domain position to be divided into occupancy each Most latter two symbol of time slot, as shown in Fig. 2, being the resource location structure diagram for sending DMRS.Compare Fig. 1（a）With Fig. 2, it can be seen that in FDD system, the time-domain position for sending DMRS is rushed with the time-domain position for sending PSS/SSS It is prominent；Compare Fig. 1（b）And Fig. 2, it can be seen that in a tdd system, the time-domain position for sending DMRS sends SSS's with being used for Time-domain position conflict.Once the time-domain position for occurring being used to send PSS/SSS conflicts with for the time-domain position for sending DMRS, it is System is preferential to send PSS/SSS so that DMRS is abandoned transmission, will so cause the waste of frequency spectrum resource, reduces frequency spectrum resource Efficiency.
In order to solve the problems, such as that R11 release protocols and release protocol before there are frequency spectrum resource waste, further carry Spectral efficient, in the R12 release protocols studied, introduces NCT（New Carrier Type, new wave-carring type）. In NCT, many reference signals are simplified, such as：CRS（Cell Reference Signal, cell reference signals) only A port is remained, the CRS after simplifying is referred to as TRS, and the resource location of occupancy is reduced so that each RB（Resource Block, resource block）In can use the increase of RE quantity, modification, which is used to sending the resource location of PSS/SSS, to be possibly realized.
Specifically, in a tdd system, for NCP, the time domain for taking the 5th symbol of subframe 1 and 6 as PSS is set Position, sets the time-domain position for taking the 2nd symbol of subframe 1 and 6 as SSS；For ECP, set and take subframe 1 and 6 The 4th symbol be PSS time-domain position, set take subframe 1 and 6 the 1st symbol be SSS time-domain position.
There are the problem of be：Since subframe 1 and 6 is typically configured as special subframe, wherein, special subframe is by DwPTS, GP Formed with UpPTS, and when DwPTS only has the TDD special subframe time slot proportions of 3 OFDM symbols, can not support configuration the 4/ or 5 symbol is the situation for the time-domain position for being used for transmission PSS；Simultaneously because time domain in resource location for sending TRS Position is arranged on the 1st and 5 symbol, is caused TRS and PSS/SSS to be unable to simultaneous transmission, is reduced synchronized tracking precision.
The content of the invention
