Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of transmission sequence number (Transmission Sequence Number, TSN) length collocation method and system.
Background technology
TD SDMA (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA) system introduces high speed downlink packet access (High Speed Downlink Packet Access, HSDPA) after, can further improve the throughput of downlink data traffic uses, 16 quadrature amplitude modulation (16Quadrature Amplitude Modulation, 16QAM) the single carrier ultimate throughput of modulation system is 2.8M bit/s, yet along with the fast development of data service, the continuous increase that the data service of down link is used has greatly promoted the demand of HSDPA multicarrier binding technology.This just needs terminal to carry out simultaneously the reception of downlink service data on a plurality of carrier waves, but, the structure of present existing MAC-hs/ehs PDU can not satisfy the demand of supporting multi-carrier HSDPA, concrete, current TSN is 6 bits, the TSN maximum can only be 64, under identical retransmission condition, multi-carrier HSDPA will enlarge the demand of TSN, in the situation of supporting multicarrier, suppose that it is 3 that the frequency that bundlees is counted N, the MAC-hs/ehs PDU number that terminal may be received at one time is N (3) times under the single carrier case, for adapting to the requirement of multi-carrier HSDPA, needing to adjust TSN sequence number size is 9 bits.Although, for the terminal of supporting the multicarrier binding, actual bearer single carrier HSDPA can support the TSN length of 9 bits when professional, yet, to supporting the terminal of multicarrier binding, the professional TSN of configuration 6 bits that only needs of actual bearer single carrier HSDPA is just enough, otherwise can waste the internal memory of terminal and base station (NodeB).So, in order to reach optimum speed, save simultaneously the memory cost of NodeB and terminal MAC layer, needing radio network controller (RNC) is 9 bits to terminal configuration TSN when distributing multicarrier binding HSDPA resource; In actual allocated single carrier HSDPA resource, be 6 bits to terminal configuration TSN.
Fig. 1 is TSN length collocation method schematic flow sheet in the correlation technique, and as shown in Figure 1, according to present consensus standard flow process, TSN length Configuration is as follows:
Step 101:RNC sets up request message/radio link reconfiguration preparation request message/or wireless link increasing request message/radio link reconfiguration request message by Radio Link (RL), carries the TSN length into the NodeB configuration.
It is professional whether step 102:NodeB decision-making is carried as multicarrier binding HSDPA, if, the binding frequency group of distributing multicarrier binding HSDPA, and be ready to message/Radio Link by wireless link response message/radio link reconfiguration and increase response message/radio link reconfiguration response message, bring RNC with the binding frequency group of the multicarrier binding HSDPA of described distribution.
Step 103:RNC reshuffles/radio bearer release/cell update acknowledge message by radio bearer (RB) foundation/radio bearer, carries the TSN length into subscriber equipment (UE) configuration.Wherein, the TSN length for the UE configuration is consistent with the TSN length that disposes for NodeB.
Step 104:UE preserves the configuration of TSN length, send radio bearer foundation/radio bearer to reshuffle/the radio bearer Release complete is to RNC.
Can find out that in existing correlation technique, the distribution of multicarrier binding HSDPA resource is determined by NodeB.For the terminal of supporting multicarrier binding HSDPA, RNC can only distribute DPCH (the Dedicated Physical Channel of master control carrier wave, DPCH) resource, the carrier wave that whether distributes multicarrier binding HSDPA resource and binding all by NodeB be ready in wireless link response/radio link reconfiguration/bring RNC in the Radio Link increase response/radio link reconfiguration response message.Therefore, RNC only is ready in the wireless link response/radio link reconfiguration of receiving NodeB/and Radio Link could determine whether current terminal reality can be carried on multicarrier and bundle on the HSDPA resource after increasing response/radio link reconfiguration response message, yet TSN length needs RNC to bring NodeB in wireless link/radio link reconfiguration preparation/wireless link increasing request message/radio link reconfiguration request, and the TSN length configuration that this moment, RNC can't make a strategic decision out optimum, if dispose larger TSN length, can waste the internal memory of terminal and NodeB.
