Fig. 1 show with cordless communication network 100 in the first node 110 that communicates of at least one Section Point 120.Communication between first node 110 and the Section Point 120 can be undertaken by the communication carrier 140 in the sub-district 150 that comprises in the cordless communication network 100 for example.Cordless communication network 100 can also comprise Control Node 130.Control Node 130 can for example be a radio network controller.Control Node 130 is the managent components in the cordless communication network 100, can be responsible for the base station (as first node 110) of control connection to Control Node 130.Control Node 130 can realize RRM; Some mobile management function, and be can be in the position that sends to Section Point 120 and encrypt before Section Point 120 receiving subscriber datas.
In certain embodiments, first node 110 can be base station, wireless communications station, fixed station, control station, radio network controller, transponder or any similar device that is used for radio communication.In certain embodiments, Section Point 120 can be a subscriber equipment, as maybe can the communicate by letter equipment of any other kind of Radio Resource of mobile cellular telephone, PDA(Personal Digital Assistant), laptop computer, computer.
This method also can be used for the switching situation in the cordless communication network 100.Switch call can have high priority.When operating in soft handover, mobile phone is connected to a plurality of sub-districts simultaneously.Therefore, keep the channel in the cell-of-origin, and the channel in the cell-of-origin and parallel use a period of time of the channel in the Target cell.Under the situation of soft handover, before disconnecting with being connected of source, foundation is connected with target.Two connect the parallel time interval of using can be of short duration or long.Soft handover can relate to the connection of using with more than two sub-districts, and for example phone can keep simultaneously with 3,4 or the connection of more a plurality of sub-districts.When under soft handover, calling out, at given time,, perhaps can merge, to produce the copy more clearly of signal to all signals at calling out the signal that can utilize optimum channel in all employed channels.According to some embodiment, the latter may be more favourable.
Therefore, according to some embodiment, particularly when operating in switching, Section Point 120 also can be base station, wireless communications station, fixed station, control station, radio network controller, transponder or any similar device that is used for radio communication.
Yet in the example depicted in fig. 1, first node 110 is base stations, and Section Point 120 is mobile cellular telephones.
In addition, has advantage under TDD mode of working in (TDD) according to the cordless communication network 100 of this method and device.
Transfer resource by the scheduling of the method in the first node 110 first node 110 places.As example, scheduling can occur in the base station 110.According to some embodiment, scheduling can be partly in Control Node 130, partly in the base station, carry out.In certain embodiments, scheduling can be carried out in Control Node 130 fully.
This method and device can be used in the wireless communication system 100 that comprises N carrier cell technology (as TD-SCDMA).
In N carrier wave TD-SCDMA system, a sub-district 150 can dispose a plurality of carrier waves 140.If each carrier wave 140 is counted as a logic district 150, then sub-district 150 is combinations of sharing the logic district 150 of identical common signal channel.Therefore, can improve the service carrier capacity of system.The purpose of introducing the N ZAP is for network capacity is provided, and this helps the improvement system.In theory, the capacity of N carrier wave TD-SCDMA system can be single-carrier system N doubly.
Therefore, can distribute air interface resource effectively.A plurality of frequencies in the N carriers carry sub-district 150.These carrier waves 140 in the sub-district 150 can be shared the common channel resources that is arranged in one of carrier wave 140.
Fig. 2 shows the resource location of the employed possible single downlink resource blocks of first node 110 and/or Section Point 120.In order to use coherent demodulation, the frequency pilot sign 210 (being sometimes referred to as reference symbol or reference signal) that for example is used for channel estimating is carried out multiplexing transmission with data 220.As shown in Figure 2, Resource Block is expanded in time and frequency dimension.
Figure 3 illustrates the time dimension of the embodiment of possible TDD radio frames 310.Carrier wave 140 is divided into frame 310, and frame 310 is divided into time slot 320,340.
That Fig. 4 shows is 110 that use by first node, be used for distributing the basic principle of the method for the resource in the cordless communication network 100 multifrequency sub-districts 150.This programme can comprise 3 kinds of algorithms: dynamic channel allocation (DCA) is admitted strategy 400, carrier wave priority algorithm 410 and time slot priority algorithm 420.Below will further explain the principle of these 3 kinds of algorithms, focus on a kind of algorithm this moment.
According to some embodiment of this method, admitting strategy 400 according to the DCA of this programme can be the algorithm that at first calls.Therefore, this method provides the set of scheme, so that higher priority service access to wireless communication system 100.Institute's requested service can be divided into 4 classes.According to the characteristic of institute's requested service, they can be divided into: non-guarantee class comprises " interactive mode " and/or " background " service class.Second class is to ensure class, comprises stream and/or speech business class.
Institute's requested service can also be asked because of whether switching.Therefore, according to some embodiment of this method, DCA admits strategy 400 according to following type all requests to be divided into following 4 kinds of service class: 1. non-guarantee/non-switching.In this case, service is non-guarantee, and does not have handoff request.2. guarantee/non-switching.In this case, service ensures, and does not have handoff request.3. non-guarantee/switching.In this case, service is non-guarantee, but has handoff request.4. guarantee/switching.In this case, service ensures, and has handoff request.
In addition, according to this method, 3 threshold values have been introduced to control the access of multiple service.First threshold can be called as tdDcaTimeslotXThreshold, and wherein, X is a number of timeslots, and scope is 0-6.Second threshold value can be called as tdDcaDINgThrh/tdDcaUINgThrh.The 3rd threshold value can be called as tdDcaDlgThrh/tdDcaUlgThrh.
Admit strategy 400 according to the DCA in up link and the down link, reserve some channel code resource at particular time-slot 320,340.In particular time-slot 320,340, when the sum of channel code resource surpasses first threshold tdDcaTimeslotXThreshold (wherein, X is the quantity of time slot 320,340, and scope is 0-6), block request.Can dispose or measure the value that first threshold tdDcaTimeslotXThreshold is set based on Interference Signal Code Power (ISCP) alternatively.ISCP is the measurement of disturbing in the particular time-slot 320,340.This measurement has multiple application, as time slot 320,340 and the Channel Assignment for the user of wireless communication system 100.
In addition, according to this method,, reserve some channel code resource of all carrier waves 140 in the sub-district 150 according to different COS.Surpass the set limit of the second threshold value tdDcaDINgThrh/tdDcaUINgThrh if be calculated as the expection number of codes of unavailability of the channel code of all carrier waves 140 or midamble sign indicating number and the quantity sum of the sign indicating number that distributed, then block non-guarantee/non-handoff request.
When the above-mentioned of the unavailability of channel code that is calculated as all carrier waves 140 or midamble sign indicating number with surpass the 3rd threshold value tdDcaDlgThrh/tdDcaUlgThrh, then block non-guarantee/switching and guarantee/non-handoff request.According to this rule, never block guarantee/handoff request according to this method.Therefore, the service that belongs to guarantee/switching class will be endowed priority, and suppose that the time slot of being discussed except time slot 320, the 340 reservation sign indicating number in each 320,340 has enough sign indicating number resources, the service that then correspondingly belongs to guarantee/switching class will be accepted all the time.In the second threshold value tdDcaDINgThrh/tdDcaUINgThrh and/or the 3rd threshold value tdDcaDlgThrh/tdDcaUlgThrh, do not comprise the sign indicating number that time slot 320,340 is reserved in each.
In order to clarify and further specify this method, below example will be discussed.Yet, it should be noted that this only is a non-limiting example, but not only be intended to limit the scope of this method that limits by independent claims.
A sub-district 150 can only comprise a carrier wave 140, and wherein, the time slot configuration between up link and the down link is 3: 3.Therefore, 3 time slots 320 are used for up link, and 3 time slots 340 are used for down link.In the TD-SCDMA system, can use 6 time slots 320,340 altogether in 1 carrier wave 140, each time slot 320,340 can carry 16 SF16 orthogonal codes, and wherein, SF (spreading factor) is 16.In each time slot 320,340, can reserve 2 sign indicating numbers, so tdDcaTimeslot1Threshold-tdDcaTimeslot6Threshold=2.Therefore, each time slot 320,340 only can use 14 SF16 orthogonal codes.3 uplink time slot 320 total total 143=42 sign indicating numbers are available.If the second threshold value tdDcaUINgThrh=14, the sign indicating number that can be used for non-guarantee/non-switching is 42-14=28.When reaching this threshold level, will block non-guarantee/non-handoff request.If the 3rd threshold value tdDcaUlgThrh=6, can be used for ensureing/sign indicating number of non-switching and non-guarantee/switching is 42-6=36.
Non-guarantee/non-handed over service will get clogged all the time.When the up link sign indicating number of sub-district has been consumed 36 SF16 channel codes, will block guarantee/non-switching and non-guarantee/handed over service.
According to this method,, must satisfy and in each time slot 320,340, reserve 2 SF16 channel codes for guarantee/handed over service.
If sub-district 150 only comprises a carrier wave 140, priority value is unnecessary, and according to this method, can call time slot priority algorithm 420 with direct assigned code.
Yet,, can in sub-district 150, dispose carrier wave more than one in order for example to support the N carrier wave.Can in sub-district 150, dispose only main carrier 140.In addition, according to some embodiment, can in sub-district 150, dispose 0-5 auxilliary carrier wave.
Therefore, when will be at the special services Resources allocation, at following carrier wave priority algorithm 410, priority sequence that must all candidate carrier of definition.
Each carrier wave can be by for example Control Node 130 imparting system priority.Priority limit from 1 to 6, wherein, the 1st, highest.Priority value can be predefined, the configuration or according to some embodiment tuning dynamically arranging Network Based.Based on the priority of carrier wave in the sub-district 150, consider that at first load can satisfy the limit priority carrier wave 140 of service request.
If comprise the carrier wave more than in the sub-district 150, these carrier waves will be divided into two sections: voice preference carrier wave section and data, services preference carrier wave section.Can dispose or the tuning number of carriers that dynamically arranges at every section division Network Based.Ratio can depend on for example business model.
When being services selection carrier wave 140, must calculate all residue codes in all uplink/downlink time slots 320,340 in the sub-district of in each time slot 320,340, being reserved 150 of sign indicating number at all carrier waves according to this programme.
According to some embodiment of this method, can calculate each time slot load 320,340 in the total load of each carrier wave in the uplink/downlink and the uplink/downlink.Reserve the sign indicating number if the institute in carrier wave 140 withs a hook at the end, all sign indicating numbers of uplink/downlink then can be selected carrier wave 140 more than the demand sign indicating number in the carrier wave 140.
For current service, can use same procedure to select all available carrier wave, and can only select up link and down link condition to satisfy those carrier waves of current service simultaneously.
The priority configuration of all candidate carrier can be disposed based on carrier system.As previously mentioned, all unavailable carrier waves have been assigned from high to low.In addition, all unavailable carrier waves are to be configured in a section in two sections (segment of speech and/or data, services sections).If all carrier waves have some different priorities, then limit priority carrier wave 140 will be configured in the front end of arrangement.Therefore, the carrier wave 140 of limit priority will at first be considered to have.
If exist have identical systems priority more than a carrier wave 140, then for the independently service of 3.4kbps signaling/CS speech (12.2kbps), at first the carrier wave in the voice preference section is put into the candidate and arranged, and can in them, have of low load and give higher priority.Then, the carrier wave in the data, services preference section can be put into the candidate and arrange, and compare, can give higher priority to carrier wave 140 with higher load with the carrier wave that hangs down load in the data, services preference section.
For other services, at first the carrier wave in the data, services preference section is put into arrangement, and higher load will have higher priority; Then, in turn, compare, to having the assignment of carriers higher priority of low load in the voice preference section with the carrier wave in the voice preference section.
Adopting and can give mode like the priority class for carrier wave according to carrier wave priority algorithm 410, can be each time slot 320,340 configuration-system priority in uplink/downlink.After having selected a carrier wave 140, can select time slot 320,340 based on time slot priority in up link and the down link and time slot load respectively.Can only select load to satisfy those time slots 320,340 of service request.
When candidate carrier disposes, can distribute suitable time slot 320,340 and sign indicating number according to time slot priority algorithm 420 in priority sequence.At this moment, can carry out time slot 320,340 and sign indicating number distribution trial to a carrier wave, distribute to attempt originating in the limit priority carrier wave until the lowest priority carrier wave, up to find can satisfy service request, have the suitable carrier wave 140 of suitable time slot 320,340 and sign indicating number till.
For the ease of reader understanding's this method of knowledge shortcoming, can give the non-limiting example of the function of output time slot priority algorithm 420.This example relates to the sub-district 150 that comprises 3 carrier waves.After at first having carried out carrier wave priority algorithm 410, elect second carrier wave and the 3rd carrier wave as candidate carrier, and it is put into priority query in order.Then, will distribute time slot 320,340 and sign indicating number.At first, time slot in the first carrier and sign indicating number in the priority query will be attempted distributing.If attempt failure, then in priority query, newly attempt in next carrier wave 140 grade.In case can become distribution of work time slot 320,340 and sign indicating number, just can call and admit control 400 to judge whether the power related resource is available.
