Technical field
The present invention relates to a kind of dynamic indication method of high speed descending packet access time slot occupation, relate in particular to the dynamic indication method of the multi-carrier-wave high-speed down-link grouped accessing system Time Slot Occupancy of communication field.
Background technology
3GPP (third generation collaboration items tissue) has introduced high speed downlink packet access (HSDPA:Highspeed oownlink PacketAccess) characteristic at the version Releases5 of 3G (3G (Third Generation) Moblie technology) standard; Its purpose is to provide the downlink grouping traffic of higher rate, increases downlink capacity.Based on UMTS (UMTS) R4 framework, HSDPA is through introducing adaptive coding and modulating (AMC:Adaptive Modulation and coding), mixing automatic repeat requests technology such as (HARQ:Hybrid Automatic Retransmission Request) and achieve the above object.
Defined a series of among the UTRAN (UMTS grounding wireless access network) with HSDPA relevant physical channel, transmission channel and processing procedure.Downstream data packet is multiplexed into descending transmission channel with the mode that happens suddenly, and------high speed descending sharing channel (HS-DSCH:High Speed Downlink SharedChannel), transmission channel HS-DSCH are mapped to high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH:High Speed Physical Downlink Shared Channel) again.This physical channel is that a plurality of users share with the mode that time-division or sign indicating number divide in the sub-district.HS-PDSCH Transmission Time Interval (TTI:Transmission Time Interval) is 5ms.HS-PDSCH carries user's data information; And the phase related control information that is used for the HS-PDSCH reception transmits through the High-Speed Shared Control Channel of following (HS-SCCH); Article one, HS-SCCH is used for the transmission of uplink feedback information corresponding to a high-speed shared information channel (HS-SICH).The TTI that these three kinds of physical channels all are 5ms is that unit handles and transmits, and is multiple users share.In addition, for the transmission of RRC signaling, 3GPP has also defined the accompanied by physical channel of up-downgoing in R5, is used to carry the relevant RRC signaling with HSDPA.
In 3GGP LCR TDD standard, each physics subframe duration is 5ms, and each subframe is made up of 7 conventional time slots and 3 special time slots, and is as shown in Figure 1.In 7 conventional time slots, time slot TS0 always distributes to down link, and TS1 always distributes to up link, and other conventional time slots then can be configured to the upstream or downstream link neatly, but ascending time slot needs configuration continuously.
On the HS-SCCH channel, use 5 bit information positions to come at present to UE indication time interval resource; And the method for the static state that adopts indication; That is, support 5 time slots to be used for descending HS-PDSCH channel at most, and these 5 bits have fixedly been represented TS2, TS3, TS4, TS5, TS6.
But in the TD-SCDMA system, not only TS2, TS3, TS4, TS5, TS6 can be used for downlink transfer, and TS0 also can be used for downlink transfer, and press the design of existing HS-SCCH signaling, can't satisfy this demand.For the multiple time slot configuration structure of compatibility, in the HS-SCCH channel, need time slot indication information bit length to be set by the descending time slot (6 time slots) of maximum possible.Because in time-division synchronous CDMA TD-SCDMA system; The uplink and downlink timeslot transfer point is variable; If the way that also adopts 5 bits to fix indication will cause the waste of information bit; Under some time slot configuration structure, will make the signaling efficiency of transmission descend, cause the waste of transfer resource, increase the transmission load of control information.

Embodiment
The present invention proposes a kind of dynamic indication method in multi-carrier-wave TDD system, through setting up dynamically associating of indicating mode and structure of time slot, number of carriers, thereby improve the efficient of indication.
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
First embodiment
In the present embodiment, system takies the Time Slot Occupancy information indicating bit of a configuring fixed N bit in the indication information structure at the time interval resource of HS-SCCH channel.As shown in Figure 2, present embodiment N=5, and the information of these 5 bits is transferred to a UE, but system can send different Time Slot Occupancy information for simultaneously a plurality of UE.When this bit during corresponding to certain time slot, be 1 like its value, represent that this time slot is occupied, be 0 like value, it is occupied to represent that this time slot does not have, can certainly be opposite.In addition, this bit also maybe be invalid, promptly do not indicate the seizure condition of any one time slot.
The method that the present embodiment time slot occupies dynamic indication may further comprise the steps:
Step 1: be set under the combination of each uplink and downlink time slot configuration structural information and carrier number; Each maybe occupied descending time slot the situation that takies in the HS-SCCH of regular length channel time slot resource occupation indicating structure corresponding information bit indicating mode (value that indicating mode is generally an information bit is used to indicate the situation that takies of a descending time slot; Present embodiment also has a kind of special circumstances to explain hereinafter), and with this dynamically associate the relation be kept among NodeB and the UE;
Present embodiment (is not limited to preserve with this form with the form of state reference table certainly.) put down in writing above-mentioned information, as follows:
The dynamic dial gauge of the time slot position during N=5:
When carrier number and uplink and downlink time slot configuration were confirmed, number and position that maybe occupied descending time slot can be confirmed.Note when carrier number greater than 3 the time; The uplink and downlink time slot configuration is still continued to use original definition; Be that descending time slot number in the uplink and downlink time slot configuration still is used for the descending time slot number of representing that TS2 disposes to TS6, but this moment, the TS0 time slot also can be used for distributing to UE, for example:
When carrier number greater than 3; And the uplink and downlink time slot configuration is when being 3:3; By rule; TS0 and TS4～TS6 are descending time slot, and the situation that takies of TS0 time slot is that b1 indicates by the 1st information bit that time interval resource takies in the indication information structure, and the situation that takies of TS4, TS5 and TS6 time slot is that b3, b4, b5 indicate by the 3rd, 4,5 information bit in this structure respectively.The 2nd information bit is that b2 does not then indicate any one descending time slot.
When carrier number smaller or equal to 3; And the uplink and downlink time slot configuration is when being 2:4; By rule; TS2～TS6 is a descending time slot, and it is that b2, b3, b4, b5 indicate that the situation that takies of TS2, TS3, TS4, TS5 and TS6 time slot takies the 2nd, 3,4,5 information bit in the indication information structure by time interval resource respectively.The 1st information bit is that b1 does not indicate any one descending time slot.
This shows that under the situation of different uplink and downlink time slot configuration structures and carrier number, the information that time interval resource takies the information bit indication in the indication information structure is different, is a kind of dynamic indication method.It should be noted that the setting of this corresponding relation is not unique.But the interrelational form in the table makes each information bit time slot corresponding relatively more consistent.Promptly at carrier number greater than 3 o'clock, be under the situation of 1:5 except the uplink and downlink time slot configuration, TS0, TS3, TS4, TS5 and TS6 correspond respectively to b1, b2, b3, b4, b5, when wherein certain or a plurality of descending time slot maybe be occupied, with the information position 1 of correspondence.Smaller or equal to 3, TS2, TS3, TS4, TS5 and TS6 correspond respectively to b1, b2, b3, b4, b5 at carrier number, when wherein certain or a plurality of descending time slot maybe be occupied, with the information position 1 of correspondence.
Especially, when carrier number greater than 3, and the uplink and downlink time slot configuration is when being 1:5; Angle from system; Each the time be carved with 6 descending time slots and can distribute, but system can all not distribute to a UE to 6 descending time slots, and UE is as having distributed TS0 time slot other descending time slot of then not reallocating.Because in case dispatch certain UE, then the code channel resource for this UE distribution is certain to greater than 1, so its time slot occupies and has at least one not to be 0 in the indication information.Therefore complete 0 state can indicate certain time slot occupied separately.Therefore, system will be through being configured to b1+b2+b3+b4+b5=0 to the information bit of certain UE, and promptly all information bits are at 0 o'clock, represent that then this UE can only obtain the resource on the TS0 at current time.At this moment, other UE can also use other descending time slots.The situation that takies of the assignable TS2 of these UE～TS6 time slot is indicated through information bit b1～b5 respectively, as above shown in the table.
Above-mentioned related information can be kept among UE and the NodeB according to agreement in advance, also can notify UE and NodeB respectively by RNC after, preserve by UE and NodeB.
Step 2:Node B and UE obtain the uplink and downlink time slot configuration structure and the carrier number information of this sub-district;
The method that RNC obtains above-mentioned information can be: RNC sets up in the process in the sub-district, through the uplink and downlink time slot configuration structural information and the carrier number of RRC high-level signaling notice NodeB current area.
The method that UE obtains above-mentioned information can be: all UE in the uplink and downlink time interval resource configuration structure information notifying cell of sub-district, UE obtains this information through monitoring broadcast channel to RNC through broadcast channel.RNC sets up in the process at the Radio Link of UE, through the carrier wave configured number of high-level signaling notice UE current area;
But the present invention is not limited to these modes.
Step 3:NodeB certain UE of scheduling also distributes the HS-PDSCH code channel resource for this UE; According to the uplink and downlink time slot configuration information of current area, carrier number information and this moment descending time slot and time interval resource take the incidence relation of information bit in the indication information structure, the value of relevant information position in the HS-SCCH channel time slot resource occupation indication information structure is set by the situation that takies of descending time slot;
By current standard, the allocation strategy of TS0 comprises: A, and main carrier TS0 can not be shared by the HS-PDSCH channel; B, the TS0 of two subcarriers adjacent with main carrier frequency equally can not be shared by the HS-PDSCH channel; C, with the TS0 of non-conterminous all subcarriers of main carrier frequency can be shared by the HS-PDSCH channel; D does not have the idle broadcast of monitoring the sub-district constantly from main carrier P-CCPCH channel for avoiding UE, and NodeB can not give the TS0 resource on the corresponding HS-PDSCH channel continuous dispensing subcarrier of same UE.
In brief, TS0 generally is used to send broadcast, but at carrier number greater than 3 o'clock, can be used for the HS-PDSCH physical channel with the TS0 time slot of the non-conterminous auxilliary carrier wave of main carrier frequency.
Step 4:UE is according to the said relation that dynamically associates of the current area uplink and downlink time interval resource configuration structure, carrier number information and the preservation that obtain; Definite each descending time slot at this moment takies situation and takies information bit indicating mode corresponding in the indication information structure at time interval resource, obtains the situation that takies of each descending time slot then according to the value of corresponding information position.
Analytic method can clearly be understood according to last table.A kind of special circumstances are wherein arranged, promptly at carrier number greater than 3, and the uplink and downlink time slot configuration is when being 1:5; When resolving, judge earlier 5 whether complete 0, if be not 0 entirely, then the value of 5bit corresponds to the take situation of TS2 to TS6 respectively; If be 0 entirely, then explanation has only distributed the TS0 time slot.
Second embodiment
Present embodiment HS-SCCH channel adopts the time interval resource of variable-length to take the indication information structure, and time slot occupies dynamic indication method and may further comprise the steps:
Steps A: be set under the combination of each uplink and downlink time slot configuration structural information and carrier number; The length of HS-SCCH channel time slot resource occupation indicating structure; And the information bit of the occupied descending time slot of each possibility correspondence in this structure, this relation of dynamically associating is kept among NodeB and the UE;
In the present embodiment, the quantity of the descending time slot that the length of HS-SCCH channel time slot resource occupation indicating structure equals to dispose, each information bit are successively corresponding to a descending time slot.
The preferable employing of present embodiment can take descending time slot and information bit interrelational form one to one according to the order of sequence, and is same, can be kept in advance among UE and the NodeB according to agreement, also can notify UE and NodeB respectively by RNC after, by UE and NodeB preservation.This incidence relation also can the state reference table mode preserve.
Step B:Node B and UE obtain the uplink and downlink time slot configuration structure and the carrier number information of this sub-district, and the acquisition mode can be identical with first embodiment;
Step C:NodeB certain UE of scheduling also distributes the HS-PDSCH code channel resource for this UE; According to the uplink and downlink time slot configuration information of current area, carrier number information and this moment descending time slot and time interval resource take the incidence relation of indication information structure length, information bit; Confirm maybe occupied descending time slot quantity (can with reference to last table); The time interval resource of configuration respective length takies indication information structure (as shown in Figure 3) in the HS-SCCH channel, and by the situation that takies of descending time slot the value of each information bit in this message structure is set;
For example; When carrier number greater than 3, and the uplink and downlink time slot configuration is when being 3:3, the length of message structure is configured to 4; And the situation that takies of descending time slot TS0 and TS4～TS6 is indicated with information bit b1～b4 successively, can correspond to each information bit by the order of time slot numbering.And work as carrier number greater than 3, and when the uplink and downlink time slot configuration was 1:5, the length of message structure was configured to 6, and the situation that takies of TS0 and TS2～TS6 is indicated with information bit b1～b6 successively.
In addition, the value of each information bit indication can be provided with by following rule: when this bit is 1, represent that this time slot is occupied; When this bit information was 0, it was occupied to represent that this time slot does not have.
Step D:UE is according to the current area uplink and downlink time interval resource configuration structure that obtains and the said relation that dynamically associates of carrier number information and preservation; Confirm the length of HS-SCCH channel time slot resource occupation indication information structure this moment; And, obtain the situation that takies of each descending time slot according to the value of each information bit in this message structure.
Present embodiment adopts elongated structure, more for a long time, adopts long information bit indication at the descending time slot of system.More after a little while, adopt short information bit indication at descending time slot.Also have an advantage in addition, promptly, because the physical code channel resource of user's beared information is constant, therefore, can adopt performance better to encode, thereby improve the reliability that control channel transmits when system during according to the short indicating length of time slot configuration structure choice.
In sum, the present invention is through setting up dynamically associating of indication information and carrier wave, structure of time slot configuration, thereby with the long indication of the less bit structure of time slot of length.Because bit of every increase brings very big burden can for the physical layer transmission of eating dishes without rice or wine, influence the network coverage even.
The above is merely illustrated embodiment of the present invention; Should know that this can have many modification; This modification is not considered to break away from the spirit and the scope of illustrated embodiment of the present invention, and the conspicuous modification of all such those of ordinary skills is comprised within the scope of accompanying claims.
