Description
Technical field
The present invention relates to the CDMA communication technology, in particular, the present invention relates to a kind of method that multi-carrier district is set up and reshuffled that in TD SDMA (TD-SCDMA, Time Division-Synchronization Code DivisionMultiple Access) system, realizes.
Background technology
Mobile communication has developed into 3G (Third Generation) Moblie (3G at present, Third Generation), one of three main standard of the TD-SCDMA 3G (Third Generation) Moblie that to be in May, 2000 approved by 3GPP by International Telecommunications Union (ITU, InternationalTelecommunication Union), March calendar year 2001.As the 3G standard of time division multiplexing mode, TD-SCDMA is used as the time-division multiplex technology scheme of low spreading rate (1.28MCps, 1.28 million chips/sec) in the ITU standard.
The same with other mobile communication system, in order to satisfy the ever-increasing demand in mobile communication market, the TD-SCDMA system also need adopt and carry out the mode that multicarrier covers in same sectors/cells and increase power system capacity.
Present TD-SCDMA (being LCR TDD) standard is not considered the multicarrier characteristic.Thereby the Uu interface all carries out at a carrier frequency for operation, the configuration of Radio Resource, and a sub-district has only disposed an absolute frequency point number in the process that the Iub interface sub-district is set up; If multicarrier, then each carrier frequency is taken as a logic district.For example, for the situation of three sectors, three carrier frequency, then thinking has 9 logic district, finishes independently operation at each sub-district, also is that 9 sub-districts send pilot tone and broadcast message separately.Like this, each carrier frequency of multicarrier system all must configuration one overlap complete common signal channel, and (the BCH of broadcast channel wherein, Broadcast Channel), forward access channel (FACH, Forward AccessChannel) and paging channel (PCH, Paging Channel) all be omnidirectional channel.Then Multi-Carrier basestation when actual networking, not only transmitter power is required very high, and, under the situation of identical networking, between carrier frequency the interference of broadcast channel also very serious, the efficient of simultaneity factor is also very low.A kind of typical case as shown in Figure 1, it is a cellular mobile communications networks that works in multiple radio frequency, if this network uses the 10MHz bandwidth, each base station is operated on 6 identical carrier frequencies.If a terminal is in the sub-district intersection, it will face following particular problem:
1, Cell searching difficulty.In order to solve time division duplex (TDD, Time Division Duplex) the initial cell search problem of system under Cellular Networks, TD-SCDMA has designed unique frame structure, realizes Cell searching by descending pilot frequency time slot DwPTS.Do not have business datum in this time slot, signal to noise ratio is very high.And in network shown in Figure 1, because neighbor cell all will be at this frequency emission DwPTS, sign indicating number is different, and the base station separation is more or less the same again from the position of terminal, and terminal receives the signal to noise ratio of this pilot signal may be at-5dB, even poorer, and adjacent carrier is all similar.Like this, will make very difficulty of initial ranging.
2, terminal is measured complicated.Because each carrier wave is a sub-district, this terminal may measure contiguous 18 sub-districts among Fig. 1 similar identical signal level.In present standard, terminal is only measured 6 sub-districts the strongest, faces far away more than the sub-district of this quantity, and terminal may be absorbed in the measuring process complicated, that be difficult to differentiate fully.
3, switch difficulty.Above-mentioned measurement result is delivered to radio network controller (RNC, Radio NetworkController), will cause the difficulty that is switched and determined, and will cause the handoff procedure that do not stop, and system loading is obviously increased.The also switching determination that may lead to errors reduces the service quality of system.
4, system effectiveness is low.A large amount of measurement results are delivered to RNC, and the handoff procedure that does not stop will seriously reduce the efficient of system.
At the problems referred to above, a kind of feasible solution is exactly the zone that covers for multicarrier, adopt a main carrier frequency to add that the mode of several minor carriers realizes that multi-carrier district/sector covers, promptly only on a carrier frequency of cell/section, send pilot tone and broadcast message, other carrier frequency is as minor carrier, sub-district must have one and have only a main carrier frequency, and a plurality of frequencies use a common broadcasting, and its detailed protocol is as follows:
At each sector, from n the frequency that is assigned to, determine one as main carrier frequency, in same sector, only on main carrier frequency, send DwPTS and broadcast message (TS0).When setting up the sub-district, need clearly indicate main carrier frequency, so that NodeB determines to send broadcasting on which frequency, and in the message of channel configuration, need to increase frequency point information, so that terminal and NodeB obtain related content.
For this reason, a kind of feasible technical scheme is to revise existing message content, and the information description that increases minor carrier is so that NodeB correctly discerns the main auxiliary carrier frequency and carries out the sub-district according to the main auxiliary carrier frequency information and set up and reshuffle.
Table one has illustrated prior art to set up the minor carrier information description content that increases in the request message in the sub-district

There is following shortcoming in the above-mentioned technical scheme that the request message content modification is set up in the sub-district:
1, there is not well to utilize the information total for minor carrier increase information description with main carrier frequency, more to the message change, make scheme too complicated.For example the switching point of minor carrier is consistent with main carrier frequency, and promptly their time slot direction is consistent, then time slot direction Time Slot Direction parameter and unnecessary increase.If this parameter exists, and configuration and main carrier frequency are inconsistent, and then success can't be set up in the sub-district.
