The blunt relative position relation and PBCH information according to PSS and SSS of user equipment ability determines the duplexing type of current carrier;
Specifically, assuming that compared to traditional LTE carrier waves, new PSS and SSS relative position relation are not introduced, but introducing two kinds of new PSS and SSS running time-frequency resource position, a kind of duplexing type for determining that first kind carrier wave is combined in each new running time-frequency resource position and PBCH running time-frequency resource position.It is assumed here that two kinds of new PSS and SSS running time-frequency resources positions are respectively first position and the second place, the first position is located at the 2nd OFDM symbol of the 3rd OFDM symbol of the 1st subframe of radio frames and the 1st subframe of radio frames for PSS and SSS respectively, the second place is located at the 2nd OFDM symbol of the 3rd OFDM symbol of the 2nd subframe of radio frames and the 2nd subframe of radio frames for PSS and SSS respectively, and the method for other positions is similar.So that PBCH information is PBCH time-frequency location information as an example, and keep PBCH-cause on PBCH time-frequency location and conventional carrier.Therefore, UE can be determined the type of current carrier by PSS, SSS and PBCH relative position relation and determine the duplexing type of current carrier.Specifically, when UE detects the combination of the PSS and SSS of conventional carrier two kinds of running time-frequency resource positions and PBCH running time-frequency resource position, UE determines that current carrier is traditional FDD or TDD carrier waves;When the relative position relation that the UE relative position relations for detecting PSS and SSS are tradition LTE/TDD, and PSS and SSS, when being first position and PBCH position grouping, UE determines current carrier for first kind TDD carrier waves;When the relative position relation that the UE relative position relations for detecting PSS and SSS are tradition LTE FDD, and PSS and SSS, when being the second place and PBCH position grouping, UE determines current carrier for first kind FDD carrier waves.
