Description

The equipment and the method for the channel resource that indication distributes in the wireless communication system
Technical field
The present invention relates to wireless communication system, relate to a kind of equipment and method of the channel resource that indication distributes in the control signaling of wireless communication system in particular.
Background technology
Now, 3GPP standardization body has set about its existing system standard is carried out long-term evolution (LTE, Long Term Evolution).In the middle of numerous physical layer transmission technology, based on OFDM (OFDM, Orthogonal Frequency Division Multiplexing) downlink transfer technology and be the focus of research based on the uplink technology of single carrier frequency division multiplexing (SCFDMA, Single Carrier FrequencyDivision Multiple Addressing).Be a kind of multi-carrier modulation communication technology on the OFDM technological essence, its basic principle is the data flow of a two-forty to be decomposed into several rate data streams transmit simultaneously on one group of mutually orthogonal subcarrier.The OFDM technology is because its multicarrier character has performance advantage aspect a lot.It on the SCFDMA technological essence a kind of single carrier transmission technology, its signal peak-to-average is than (PAPR, Peak to AveragePower Ratio) lower, thereby the power amplifier of portable terminal can be with higher efficient work, enlarge the coverage of sub-district, by adding Cyclic Prefix (Cyclic Prefix) and frequency domain equalization, it is lower that it handles complexity simultaneously.
According to existing discussion result about LTE, be LTE system descending frame structure as shown in Figure 1, Radio Resource in the LTE system is meant time and the frequency resource that system or subscriber equipment can take, can (101-103) do differentiation with radio frames (radio frame) for unit, the time span of radio frames is identical with the time span of the radio frames of WCDMA system, and promptly its time length is 10ms; Each frame is subdivided into a plurality of subframes (sub-frame) (104-107), and present hypothesis is that each radio frames comprises 20 subframes, and the time span of subframe is 0.5ms; Each subframe comprises a plurality of OFDM symbols again, and according to present hypothesis, the time span of effective OFDM symbol is about 66.7 μ s in the LTE system.The time span of the CP of OFDM symbol can have two kinds, promptly the time span of short CP is approximately 4.8 μ s, the about 16.7 μ s of the time span of long CP, long CP subframe is used for many Cell Broadcast CB/multicasts and the very large situation of radius of society, short CP subframe (108) comprises 7 OFDM symbols, and long CP subframe (109) comprises 6 OFDM symbols.The minimum transfer time interval, (TTI) just equaled the time span of subframe.
Fig. 2 is a LTE system uplink frame structure, and with the downlink frame similar, the time span of its radio frames (201,202,203) is all 10ms mutually with WCDMA; Each frame is subdivided into a plurality of subframes (204-207), and present hypothesis is that each radio frames comprises 20 subframes, and the time span of subframe is 0.5ms; Each subframe comprises a plurality of SCFDMA symbols again, and according to present hypothesis, the SCFDMA symbol in the LTE system is divided into two kinds, comprise two short symbols (214 in the subframe, 215), its, length was about 33.33 μ s effective time, was called short block (Short block) in the current discussion; Simultaneously comprise 6 long symbols (208～213) in a subframe, its, length was 66.67 μ s effective time, was called long piece (Long block) in the current discussion.Short symbol is used to transmit the reference information of coherent demodulation, also can be used for transmit ascending data and control information simultaneously; Long symbol is used for transmit ascending data and control information.The minimum transfer time interval, (TTI) just equaled the time span of subframe.
In current LTE discusses, the mode that has two kinds of basic channel resources to divide.First kind is local formula transmission channel, promptly some continuous subcarriers is divided into a channel as Resource Block, and this method helps utilizing multi-user diversity, thereby higher throughput of system is provided.Another kind is the distributed transmission channel, the running time-frequency resource of promptly distributing to some users be distributed to whole with certain rules or partial-band in, thereby the gain of frequency diversity is bigger.These two kinds of channel distribution modes respectively have superiority and replenish mutually, can be applied to simultaneously in the same subframe, thereby in a subframe some users be obtained multi-user diversity gain, and the user obtains frequency diversity gain to other.
The scheduling of user data and transmission are to be base unit with the Resource Block.In current discussion, the notion of Physical Resource Block (Physical resourceblock) and virtual resource blocks (Virtual resource block) has been proposed about LTE down channel resources dividing mode.Physical Resource Block comprises M continuous sub-carriers on frequency domain, comprise N continuous OFDM symbol simultaneously in time.Virtual resource blocks is abstract to channel resource on Physical Resource Block, and virtual resource blocks is divided into distributed virtual resource block and local formula virtual resource blocks.Distributed virtual resource block is corresponding to the resource of distributed transmission channel, and local formula virtual resource blocks is corresponding to the resource of local formula transmission channel.
In current discussion, adopted the notion of Resource Unit (Resource unit) about LTE uplink channel resources dividing mode.Resource Unit is further divided into local formula Resource Unit (LocalizedRU) and distributed resource units (Distributed RU).Local formula Resource Unit comprises a continuous M subcarrier on frequency domain, comprise N long SCFDMA symbol simultaneously in time; Distributed resource units comprises the subcarrier that M frequency interval equates on frequency domain, comprise N long SCFDMA symbol simultaneously in time.It should be noted that in current discussion and be not precluded within the short SCFDMA symbol and transmit data, so the actual running time-frequency resource that takies of Resource Unit can comprise the resource in the short SCFDMA symbol.
For the convenience of narrating, the unified in the following description base unit that uses Resource Block to represent the up-downgoing dispatch channel resource of the present invention.For down direction, Resource Block is corresponding to local formula virtual resource blocks or distributed virtual resource block; For the up direction Resource Block corresponding to local formula Resource Unit or distributed resource units.
Fig. 3 is a kind of mode of channel resource of network indication distribution, and control channel comprises two classes at least, sends the user's of scheduling number in Common Control Channel; In shared control channel, send information such as the user ID comprise scheduling and resource allocation information.In this method network allocation give user's Resource Block both can be continuous also can be discontinuous.
1) network sends each user's that current subframe need dispatch sign (301,302,303), thereby obtains comprising the table about user ID of the individual element of M (M is the number of users of current subframe scheduling), and each user ID is represented with its index in table;
2) network sends the index (311,312,313) of the user ID of its carrying successively to each Resource Block, the situation that indexed resource distributes, thus obtain the table of N element, wherein N is the number of Resource Block in the system;
3) network is mapped as fixed number to the user ID index of each Resource Block
Figure A20061007398900081
Here
Figure A20061007398900082
Round in the expression, thereby total bit number that the indication resource allocation needs in the downlink signaling is
Figure A20061007398900083
Fig. 4 is the mode of the channel resource that distributes of another kind of network indication, and control channel comprises two class channels at least, and Common Control Channel is used to send the user's of scheduling number; Shared control channel is used to send information such as the user ID that comprises scheduling and resource allocation information.This method hypothesis network is continuous for each user resource allocation piece.
1) network sends each user's that current subframe need dispatch sign (401,402,403), thereby obtains comprising a table about user ID of the individual element of M (M is the number of users of current subframe scheduling);
2) network sends its type (411,412,413) to each Resource Block successively, thereby obtains the table of N element, and wherein N is the number of Resource Block in the system;
3) type of each Resource Block is mapped as individual bit, thereby total bit number that the indication resource allocation needs in the downlink signaling is N.
The step 2 of method shown in Figure 4) in, a kind of mode is that the current resource block assignments of definition bit 0 representative is given certain user, and next Resource Block is no longer distributed to this user simultaneously; The current resource block assignments of definition bit 1 representative is given certain user, and next Resource Block is still distributed to this user simultaneously.According to this rule, network obtains indexed resource assignment information bit block.Fig. 4 has shown an example (420) of this resource allocation information bit block, as shown in Figure 4, from left to right, " 0 " (421) represent that first resource block assignments is to user 1, thereafter these three resource block assignments are represented to user 2 in " 110 " (422), and last four resource block assignments in expression back, " 1110 " (423) are given user M.
The method of the described indexed resource assignment information of Fig. 3 and Fig. 4 can only be used for system all Resource Block in the current subframe are all distributed to the situation of subscriber equipment, yet several factors can cause system only to distribute a part in all Resource Block in certain subframe in the LTE system:
1) be divided into a plurality of groups when sending when the control signaling, the Resource Block that every group of subscriber equipment takies all will be a subclass of system's total resources piece, and method at this moment above-mentioned can not be worked;
2) in current discussion about LTE control signaling, the duration of resource allocation (Duration) is the mode of a very important reduction signaling consumption.When adopting this mode, the resource of distributing to certain subscriber equipment in subframe of system is effective in a plurality of subframes thereafter, this means that simultaneously system is when sub-frame allocation resource thereafter, can only distribute these Resource Block that distributed Resource Block in addition, just the part in the distribution system total resources piece;
3) owing to adopt channeling, thus the reliability that raising information is transmitted, such as the problem that solves cell boarder etc., the distribution in the no longer current subframe of a part of Resource Block in the system because of channeling, the method for Fig. 3 and Fig. 4 can not be worked.
For method shown in Figure 3, because it is mapped as fixed number to the user ID index of each Resource Block
Figure A20061007398900101
When user's number of current subframe scheduling was not 2 integral number power, its user ID index still must be used

Expression, so there is redundancy in information, the utilization of signaling bit is not very effective.

Another type definition method is: type 0: current resource block assignments is given a user, and next Resource Block is no longer distributed to this user; Class1: when current resource block assignments was given a user, next Resource Block was also distributed to same user; Do not do the branch timing when current Resource Block, next Resource Block does not distribute yet; Type 2: current Resource Block is not done distribution in current subframe, and next resource block assignments is given certain user simultaneously.
Another type definition method is: type 0: current resource block assignments is given a user, and previous Resource Block is not distributed to this user; Class1: when current resource block assignments was given a user, previous Resource Block was also distributed to same user; Do not do the branch timing when current Resource Block, previous Resource Block does not distribute yet; Type 2: current Resource Block is not done distribution in current subframe, and previous resource block assignments is given certain user simultaneously.
When generation comprised resource allocation information vectorial, a kind of method was that above-mentioned three types (type 0, Class1, types 2) map directly to numerical value 0,1,2; Another kind method is to be mapped to numerical value 0,1,2 behind above-mentioned three types of conversion order.Generate the vector that comprises the individual element of N (N equals the number of Resource Block in the system) like this in the step b), its each element is represented the distribution type of corresponding Resource Block, and it has 3 kinds of possible values.
In the step c) of the present invention, for the first method of step b), only dispatch a user when system in current subframe, just the value of M is 1 o'clock, directly obtains comprising the binary bits piece of resource block assignments information in the step b), and its number of bits is N; When system in the number of users of current subframe scheduling during greater than 1, just M was greater than 1 o'clock, system is the number of the vector that generates in the step b) as a M+1 system, and it is converted to the number of one 2 system, these 2 system numbers that are converted to have been represented the assignment information of system for Resource Block, thereby total bit number that the indication resource allocation needs in the downlink signaling is
