Description
Technical field
The present invention relates to fields of communication technology, in particular to a kind of resource allocation indicating method, a kind of resource allocation
Instruction device and a kind of base station.
Background technique
Currently, with the development of mobile internet, having emerged the applied business for largely meeting various specific functions.Wherein
Some business are lower to data delay requirement, such as receiving and dispatching mail, downloading film etc.；But in addition there are some business to data delay
There are a strict requirements, such as network on-line game, rush to purchase, rob red packet etc., this kind of business is usually required the time delay of user data
It is short as far as possible.In LTE (Long Term Evolution, long term evolution) system, Transmission Time Interval (TTI,
Transmission Time Interval) it is the important indicator for influencing user data delay.The biography that current LTE system uses
Defeated time interval is 1ms (hereinafter referred to as legacy TTI, traditional TTI) namely a subframe, and the every 1ms of transmitting terminal sends primary
Data block, receiving end can one data blocks of every 1ms reception.
In 3GPP (3rd Generation Partnership Project, third generation partner program) RAN
In (Radio Access Network, wireless access network) #69 plenary session in LTE system use shorter TTI (short
TTI, i.e. sTTI, such as 0.5ms etc.) project set up the project, research using shorter duration TTI feasibility and may
Beneficial effect.Current some documents such as R1-160942, R1-160930 quantitatively have studied the reduction of TTI duration to LTE
The influence of the data delay of system, analysis shows that, so that the Transmission Time Interval of base station, terminal is shortened using sTTI,
Correspondingly, data processing time corresponding with the Transmission Time Interval can also decrease, for example, data code modulation and
The data demodulation time can all be reduced with the reduction of data block size.In the LTE system of later release it is possible that
The case where legacy TTI and two kinds of Transmission Time Intervals of sTTI coexist, that is, the wireless system bandwidth of the same cell both included
Legacy TTI occupies resource part, also occupies resource part comprising sTTI.
A kind of mode of possible reuse pattern legacy TTI and sTTI wireless system bandwidth resource is as shown in Figure 1.It is empty
White part indicates that legacy TTI occupies resource part, and oblique line portion indicates that sTTI occupies resource part, i.e. RB1~RB n1 is
The occupied RB of legacy TTI (Resource Block, resource block), RB n1+1~RB n2 are the occupied RB of sTTI, according to
This analogizes.Wherein, several continuous RB that a resource type occupies collectively form a RB branch (resource bandwidth group),
Such as RB1~RB n1 is exactly a RB branch.Two kinds of resources type is alternately present on frequency domain, so that legacy TTI institute
The occupied RB of RB and sTTI of occupancy is uniformly or in the whole system bandwidth for being distributed in Target cell of approaches uniformity.
Using legacy TTI, if dispatching user by the way of dynamic dispatching, need each
In TTI duration all in PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) dynamically
It is designated as the RB resource of user distribution.Such as in system bandwidth be 50RB, according to current standard, the minimum unit of RB distribution
It is the RBG (RB Group, RB group) that 3 RB are constituted.In downlink using resource allocation type in the side bitmap (bitmap file)
Under formula, it is for RB istributes bit number needed for some userNamely in each legacy TTI, base station
Require the RB resource that target user's distribution is designated as using 17bit information.If also using same instruction in sTTI
Mode is the RB resource of user's distribution, then since sTTI duration is shorter, a legacy TTI generally will include multiple sTTI, then
It needs to occupy more resources to carry these RB distribution information bit, causes the relatively large overhead of Downlink Control Information.

The number of resource bandwidth group belonging to the resource block of terminal distribution, the Secondary resource distribution information are used to indicate the resource block
Resource block number in the resource bandwidth group.
Further, in the step 204, it is preferable that send institute to the terminal by physical layer descending control signaling
State first resource distribution information and Secondary resource distribution information.
It in this embodiment, specifically can be in the case where each longer period 1 and shorter second round be by physical layer
The resource allocation information that row control signaling will be indicated as the resource block of terminal distribution is sent to terminal.
To sum up, in the LTE system using sTTI, it is first determined the first duration numerical value of longer period 1 and shorter
Second round the second duration numerical value, and then sent according to longer cycle to terminal and be used to indicate resource for the terminal distribution
The first resource of the number of resource bandwidth group belonging to block distributes information, and according to compared with short cycle to terminal transmission be used to indicate for
The Secondary resource of resource block number of the resource block of the terminal distribution in above-mentioned resource bandwidth group distributes information, due to shorter
Only need to be expressed as RB (resource block) number of the resource block of terminal distribution in affiliated resource bandwidth group in period, without
Indicate the RB number in whole system bandwidth, thus required bit quantity is reduced, to reduce opening for Downlink Control Information
Pin.
Below with the first duration numerical value of period 1 for 1 legacy TTI and the second duration numerical value of second round
For 1 sTTI, system bandwidth includes 20 RB altogether, be divided into 4 RB branch, each RB branch have for 5 RB into
Row explanation, wherein a legacy TTI includes 7 sTTI.
So, according to current standard, under 20RB system bandwidth, the minimum unit of RB distribution is the RBG that 2 RB are constituted.
According to RB identical in the case of legacy TTI distribute indicating mode, then needed in each sTTI duration usingIt just needs to occupy 7 × 10=70bit in a legacy TTI duration；And according to skill of the invention
Art scheme needs to indicate that RB branch is numbered using 2bit when legacy TTI starts, needs to make in each sTTI duration
WithIt needs to occupy 2+3 × 7=23bit in a legacy TTI duration, it is seen then that effectively reduce instruction
RB distributes the bit number of information, to reduce Downlink Control Information expense.
It should be noted that the RB that the UE (User Equipment, user equipment) is distributed is only in a long period
It can be moved in this specific RB Branch, and then in view of sTTI is typically applied to the preferably middle low speed of channel condition
Rotating ring border, and the time variation of channel is generally lower in middle low speed mobile environment, so because being fixed on one in a long period
The effect of the selection gain reduction of frequency caused by RB Branch can be ignored.
To sum up, the affiliated RB branch of RB that UE distribution is expressed as by using long period RB resource allocation information is compiled
Number, RB number of the RB of UE distribution in affiliated RB branch is expressed as using short cycle RB resource allocation information, due to
RB number in RB branch belonging to only needing to indicate in short cycle, does not need to indicate the RB number in whole system bandwidth,
Bit quantity needed for thus can be many less, to reduce the expense of Downlink Control Information.
