Description
Technical field
The present invention relates to mobile communication system compressed mode transmission control method, relate in particular to ascending reinforced special channel compressed mode transmission control method.
Background technology
Compare with other mobile communication system, broadband CDMA system (Wide Code Division Multiple Access), be to have introduced compressed mode techniques in the WCDMA system, by in transmission and receiving course, carrying out of short duration interruption, the part time slot is not used in transfer of data, carries out the control channel of power measurement, other system/carrier wave between frequency and catches and the direct-cut operation operation.
Compact model claims the time slot pattern again, and its principle is by data are compressed on time domain, vacates transmission gap and carries out measurement to other frequency or system, thereby avoided losing of data.The generation of WCDMA agreement regulation compressed mode frame has three kinds of methods: 1) high-level scheduling (High Layer Scheduling); 2) spreading factor (Spreading Factor) reduces by half, i.e. SF/2; 3) punching (Puncturing).In above-mentioned three kinds of methods, the compact model of punching is to reduce character rate by the punching technology in the physical layer multiplex process, owing to be a kind of lossy compression method method, do not do consideration during practical application, and in up-to-date protocol specification, this compact model method has been removed.The high-level scheduling compact model is by transformat combination (the Transport Format Combination) TFC that is allowed is retrained, to reduce the speed from high level data.
It then is that spreading factor by with a compression radio frames reduces by half that spreading factor reduces by half, and sends so that information data is removed in condensed frame the remaining time slots of transmission gap.Because the minimal frequency spreading factor that the frame structure of uplink special physical channel (Dedicated Physical Data Channel) DPDCH and descending DPDCH is supported is 4, therefore for general DPCH, the compact model that spreading factor reduces by half is only supported the SF greater than 4.For E-DCH (ascending reinforced special channel), because the agreement regulation can be supported the frame structure of SF=2, so the compact model that E-DCH adopts spreading factor to reduce by half should be supported SF=4, but the transmission control mode of prior art can not be applied among the E-DCH, can't reduce by half by spreading factor to vacate transmission gap and carry out measurement to other frequencies or system.
