Description
Technical field
The present invention relates to wireless communication field, relate in particular to the distribution method and base station and the system that follow channel in the HSPA system.
Background technology
HSPA (High Speed Packet Access, high-speed packet inserts) be HSDPA (High Speed Downlink Packet Access, high speed downlink packet inserts) and HSUPA (High Speed Uplink Packet Access, the high speed uplink packet access) general designation of two kinds of technology, by adopting AMC (Adaptive Modulation and Coding), HARQ (mix automatically and retransmit), high order modulation technology such as (16QAM), and in base station side realization fast dispatch, thereby the variation of reflection subscriber channel that can be quick self-adapted obtains higher user's peak rate and cell data throughput.
At present, the channel that TD-SCDMA HSDPA system relates to comprises 5, is respectively:
HS-PDSCH:High-Speed Physical Downlink Shared Channel, High-Speed Physical Downlink Shared Channel is the HSDPA Traffic Channel, is used to carry each UE (subscriber equipment) high level data;
The shared information channel of HS-SICH:High-Speed Shared Information Channel for HS-DSCH high speed descending sharing channel, it is the HSDPA ascending control channel, be used to carry and HS-DSCH (high speed descending sharing channel, the corresponding physical channel is HS-PDSCH) relevant signaling information, these signaling informations can comprise that HARQ confirms/deny to reply the channel quality indication (CQI) of (ACK/NACK), down link;
HS-SCCH:High-Speed Shared Control Channel, High-Speed Shared Control Channel, it is the HSDPA down control channel, the signaling information that is used for carries downlink, these signaling informations can comprise channelization code set, gap information, modulation system, transmission block size, HARQ process number (HARQ Process ID), redundancy versions, new data flag, HS-SCCH cyclic sequence number and UE ID etc.;
The up channel of following of ULA-DPCH:HSDPA is used to carry each UE (subscriber equipment) high level data and the up signaling of following;
The descending channel of following of DL A-DPCH:HSDPA is used for bearing downlink and follows signaling, is used for the physical layer control (comprising synchronously and power control) of up DPCH simultaneously.
Wherein, HS-DSCH always follows a descending DPCH channel and one or more HS-SCCH channels.Each UE will need a descending DPCH channel, for the up DPCH channel of UE and ascending control channel HS-SICH provide SS synch command, thereby guarantee descending DPCH and up DPCH channel and ascending control channel HS-SICH synchronously.
TD-SCDMA HSDPA power system capacity is mainly by number of carriers, the decision of HS-PDSCH number of timeslots, but the access customer number amount is subjected to following the restriction of channel.The Typical Disposition of HSDPA system resource can be as shown in Figure 1, and the Typical Disposition of HSPA (comprising HSDPA and HSUPA) system resource can be as shown in Figure 2.By Fig. 1 and Fig. 2 as can be known, follow channel at descending TS6 configurating downlink, in the HSDPA system, only be 6, in the HSPA system, only be 3, no matter the i.e. situation of other channel resources, only can support 6 or 3 users with regard to descending following with regard to the channel, obviously this typical HSPA resource distribution meeting restriction number of users that single carrier inserts.
In order to address this problem, in the present technology and standard, increased the support of following the multiplexing of channel function to descending, divide multiplex mode to realize that it is in the nature time division multiplexing, promptly increases the control cycle of L1 by frame.The descending frame branch multiplexer mode of channel of following comprises:
2 times of frames divide multiplexing: descending to follow channel to carry out multiplexing by 2, promptly is adjusted into the L1 control of per 2 TTI (80ms) by the L1 control of original each TTI (as 40ms);
4 times of frames divide multiplexing: descending to follow channel to carry out multiplexing by 4, promptly is adjusted into the L1 control of per 4 TTI (160ms) by the L1 control of original each TTI (as 40ms).
At the HSDPA system of resource distribution shown in Figure 1, the configurating downlink control channel is 2 among the descending TS6, follows the channel time spent but 6 of residues are descending, adopt descending follow the channel multiplexing technology after, different frame divides the access UE quantity under the multiplexer mode as shown in table 1:
Table 1
Though divide multiplex mode can improve the descending service efficiency of following channel by frame, increase access customer number, can at first not become the bottleneck of HSDPA system access customer number, still, after increasing the control cycle (increasing to 2 or 4 times by 1 TTI) of user L1, its performance of eating dishes without rice or wine can descend thereupon.All be to reduce the performance that the control cycle of physical layer is eated dishes without rice or wine with raising in wireless communication system as far as possible, improve system effectiveness, and the descending frame of channel of following of existing HSDPA system divides multiplex mode, is to be the ability that cost exchanges maximum access customer number for the sacrifice performance of eating dishes without rice or wine.
Under the propagation model of urban district, by emulation, after the L1 control cycle increased to 2 TTI by 1 TTI, the demodulation threshold of channel can worsen 1～2dB, increases to 4 TTI, and demodulation threshold can worsen 4～5dB.No matter 2 times of frames divide multiplexing or 4 times of frames divide multiplexingly, the deterioration of the demodulation threshold of channel will cause the contraction of its covering power, can influence the HSDPA power system capacity when serious.
The descending frame of channel of following of existing HSDPA system divides multiplexing multiple to be provided with according to maximum access customer number, and is to fixedly install.For example, according to 4 times of multiplexing coefficient settings, but its maximum access customer number is: the 4 * descending number of channel of following.Even in the less situation of user, also be earlier according to code channel multiplexing after, next bar of reallocating is followed channel, this will cause the multi-user shared channel of following, and also have the more channel resource free time of following, so that reduce systematic function.As seen, there is reasonability scarcely in the existing channel multiplexing mechanism of following.

Embodiment
Follow the problem of the fixed configurations mechanism existence of channel multiplexing at existing HSPA system, the embodiment of the invention is according to current HSPA number of users, dynamically adjust the channel allocation mode of following, thereby when satisfying the demand that inserts the user, guarantee to insert user's the physical property of following channel as far as possible.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Referring to Fig. 3 a, for the HSPA system of the embodiment of the invention follows the schematic flow sheet of method for channel allocation, this method comprises the steps:
Step 301, determine current HSPA number of users;
The HSPA number of users that step 302, basis are determined judges whether to adopt and follows multiplexing of channel mechanism, promptly whether need follow multiplexing HSPA user on the channel; If the HSPA number of users greater than the channel quantity of following of system, then need followed multiplexing HSPA user on the channel, execution in step 304; Otherwise, need not follow multiplexing HSPA user on the channel, execution in step 303;
Step 304, employing follow channel multiplexing mechanism to follow channel resource for current HSPA user distributes.
In the above-mentioned steps 303,, can adopt the existing channel multiplexing mechanism of following, divide multiplexing or 4 frequencys multiplication are divided multiplexing as 2 frequencys multiplication when judge to need adopting when following channel multiplexing mechanism; Also can be when judgement need employing to follow channel multiplexing mechanism, further definite multiplexing multiple that is adopted and the applied channel of following of this multiplexing multiple, under this kind situation, shown in Fig. 3 b, the step 304 of above-mentioned flow process can comprise the steps:
The multiplexing multiple that step 3042, basis are determined carries out the time slot division to the corresponding channel of following, and uses to the HSPA user of respective numbers the time slot allocation that marks off.
In the above-mentioned steps 3041, determine the multiplexing multiple adopted and adopt this multiplexing multiple follow channel the time, can determine that all follow channel all to adopt identical multiplexing multiple, as 2 times multiplexing or 4 times multiplexing, concrete multiplexing multiple can be determined according to current HSPA number of users, to insert the user as much as possible, for example for including 6 descending HSDPA systems that follow channel among the descending TS6, when the HSDPA number of users was no more than for 12 (promptly 2 frequencys multiplication are divided multiplexing maximum access customer number), it is multiplexing to adopt 2 frequencys multiplication to divide, when the HSDPA number of users surpassed 12, it was multiplexing to adopt 4 frequencys multiplication to divide.Can also partly follow channel to adopt low power multiplexing (multiplexing) as 2 times, part follows channel to adopt high power multiplexing (multiplexing as 4 times), it is multiplexing that part follows channel not adopt, adopt 2 times multiplexing, 4 times multiplexing and do not adopt the channel quantity of following of multiplexing mechanism to determine according to current HSPA number of users, preferably, the embodiment of the invention adopts this kind mode to follow channel resource allocation, and the principle that this method of salary distribution is followed is:
Under the prerequisite that as often as possible inserts current HSPA user, the preferential low power multiplexing (multiplexing) that adopts as 2 times, when all following channel to adopt that low power is multiplexing can not to insert current HSPA user fully, follow channel to adopt multiplexing (multiplexing) of higher multiple to part as 4 times, in the time still can not inserting current HSPA user fully, all follow channel to adopt this high multiple multiplexing (4 times multiplexing).
Said method is applicable to the up channel or the descending resource allocation process of following channel followed of HSUPA and HSDPA system.According to above principle, at the descending distribution of following channel of HSPA system, establishing current HSPA number of users is N, and descending to follow the quantity of channel be M, adoptable multiplexing multiple comprise 2 times multiplexing and 4 times multiplexing, the then descending distribution condition of channel of following comprises:
When N≤M, do not adopt multiplexing mechanism;
When M＜N＜2M, N/2 is rounded, the gained end value is exactly to adopt 2 times of frames to divide the multiplexing descending channel quantity of following, and all the other descending channels of following do not adopt multiplexing mechanism;
When N=2M, all descending channel of following adopts 2 times of frames to divide multiplexing;
When 2M＜N＜4M, N/4 is rounded, the gained end value is exactly to adopt 4 times of frames to divide the multiplexing descending channel quantity of following; (N-(end value after N/4 rounds) * 4)/2 are rounded, and resulting end value is exactly to adopt 2 times of frames to divide the multiplexing descending channel quantity of following, and all the other descending channels of following do not adopt multiplexing mechanism;
When N=4M, all descending channel of following adopts 4 times of frames to divide multiplexing.
As can be seen, when adopting the embodiment of the invention to follow channel resource allocation, less and do not need to adopt multiplexing mechanism just can insert under active user's the situation at number of users, then do not adopt the channel multiplexing mechanism of following, thereby when guaranteeing to admit the active user, keep the good channel performance; Along with number of users increases gradually, can progressively start the multiplexing mechanism of higher ability, though adopt channel multiplexing mechanism can cause following the performance of channel to descend to some extent, can admit more user; Along with number of users reduces, can progressively start the multiplexing function of lower ability, thereby when admitting the user as far as possible, make and follow the performance of channel progressively to improve.
Below being that to follow channel resource be example to user's allocation of downlink in the HSDPA system, HSPA system to the embodiment of the invention follows the assigning process of channel to be described in detail, and the channel allocation mode of following of the embodiment of the invention is fixed 4 times of frames and divided multiplex mode to compare with existing.
As shown in Figure 1, comprise 6 descending channels of following among the TS6 of HSDPA system, if it is multiplexing to adopt 4 times of frames to divide, then can insert 24 users at most, the HSDPA user who establishes current access is N.
When N≤6, do not need to adopt frame to divide multiplexing mechanism, as shown in table 2, each user is assigned a descending channel of following.And, when adopting 4 times of frames of existing fixed to divide multiplexing mechanism, need follow multiplexing a plurality of users in the channel descending at this kind situation, and the more descending channel resource free time of following is arranged simultaneously, this will cause user's channel quality to descend; By contrast, each user is assigned a descending channel of following in the present embodiment, and it is followed the performance of channel to be better than to adopt and fixes 4 times of frames and divide multiplex mode, and the channel resource utilance is also higher.
Table 2
When 6＜N≤12, the descending channel of following of part adopts 2 times of frames to divide multiplex mode, and part is descending follows channel not adopt frame to divide multiplex mode (in N＜12 o'clock); The perhaps all descending 2 times of frames of channel employing of following divide multiplex mode (when N=12), and are as shown in table 3.And, when adopting 4 times of frames of existing fixed to divide multiplexing mechanism, need follow multiplexing 4 users in the channel descending at this kind situation, and the more descending channel resource free time of following is arranged simultaneously, this will cause user's channel quality to descend; By contrast, only follow multiplexing 2 users on the channel in the present embodiment, under the situation of N＜12 descending, also having part, descending to follow channel not adopt frame to divide multiplexing, obviously, it is followed the performance of channel to be better than to adopt and fixes 4 times of frames and divide multiplex mode, and the channel resource utilance is also higher.
Table 3
When 12＜N≤24, part is descending follows channel to adopt 4 times of frames to divide multiplexing (N＜24 o'clock), perhaps all descendingly follows channels to adopt 4 times of frames to divide multiplexing (N=24), as shown in table 4.Adopt 4 times of frames to divide when multiplexing at the descending channel of following of part, according to number of users what, part will be arranged, and descending to follow channel to adopt 2 frames to divide multiplexing, even also having part, descending to follow channel not adopt frame to divide multiplexing.And, when adopting 4 times of frames of existing fixed to divide multiplexing mechanism, need follow multiplexing 4 users in the channel descending at this kind situation; And it is multiplexing to have adopted 2 times of frames to divide in the present embodiment, divides multiplexingly than 4 times of frames, and obviously user's channel quality is better, even some is descending, and to follow channel also may not adopt frame to divide multiplexing, divide multiplexingly than 4 times of frames, obviously user's channel quality is better, and the channel resource utilance is also higher.Under the situation of N=24, adopt the 4 times of frames of fixing of prior art to divide multiplex mode and the descending channel allocation mode of following that adopts the embodiment of the invention, its user channel quality does not have notable difference.
Table 4
In the embodiment of the invention, HSPA user is being multiplexed into when following on the channel, in order to guarantee systematic function as far as possible, can determine which user is started multiplexing function or the user who starts multiplexing function is started higher multiplexing function according to factors such as user channel quality; Perhaps, determine which user is not started multiplexing function as far as possible or the user who starts multiplexing function is started lower multiplexing function according to factors such as user channel quality.
Table 5 has provided the strategy that the channel multiplexing function is followed in a kind of startup, wherein, scene one expression needs to start the situation of higher multiplexing function (promptly adopting higher multiplexing multiple) because of number of users increases, scene two expressions need to start the situation of lower multiplexing function (promptly adopting lower multiplexing multiple) because of number of users reduces.
Table 5
In the table 5, user SPI represents the dispatching priority indication, and GBR represents minimum assurance speed.
Can also quantize the grade that this user of expression starts multiplexing function by weighting scheme according to various factors, realize starting the strategy of following the channel multiplexing function.For example, for the listed various factors of enumerating of table 5, its weights computing formula is as follows:
W=W1*SPI+W2* channel quality+W3* capacity requirement+W4*GBR+W5* power headroom+...;
Wherein, W is the grade that calculates, and Wi represents the weight coefficient of each factor.
Because every adjustment once needs to take place the reprovision process of a physical channel, therefore, can distinguish consideration in conjunction with the situations such as performance of physical channel reprovision, such as, when channel performance is better, can adopt above-mentioned strategy dynamically to adjust to following channel resource allocation.
In the HSPA system, follow the resource allocation of channel to be undertaken by the base station.When arrived in dispatching cycle, the base station can be adopted with the upper type and follow channel resource for HSPA user distributes according to current HSPA number of users.Wherein, the base station can obtain current HSPA number of users by the mode of real-time detection, also can determine current HSPA number of users according to the traffic measurement model.The traffic measurement model is the historical record of traffic measurement, can obtain the number of users situation of day part by this model.Consider factors such as traffic growth, when determining that according to the traffic measurement model active user counts, may deviation be arranged with actual conditions, therefore can suitably adjust (as situation about increasing fast the number of users of determining by the traffic measurement model at business, the number of users of determining according to the traffic measurement model is computed weighted, thereby finally determine current HSPA number of users).
In the another embodiment of the present invention, can be according to the traffic measurement model, determine the number of users (also can suitably adjust) of day part to the number of users of determining, and according to the number of users of day part, it is that HSPA user's distribution follows the mode of channel resource (to comprise and whether adopt multiplexing mechanism that employing is determined with upper type, adopt the multiplexing multiple in multiplexing when mechanism and follow channel etc. accordingly), thus determine the day part correspondence follow the channel resource allocation mode.When arrived in dispatching cycle, the base station adopted the corresponding channel resource allocation mode of following to follow channel resource allocation according to the residing period of current time.Further, the base station is when following channel resource allocation, if the method for salary distribution that is adopted is to follow the channel multiplexing mode, can follow the channel multiplexing function policy to follow channel resource allocation and dynamically adjustment with reference to above-mentioned startup.
