Position, and be assigned in described in the resource block group of this end user device, it is assigned to the user equipment at least
The configured information field bit of one resource block.
Specifically, the number of the Physical Resource Block included in different bandwidth is different, the thing that each resource block group includes
The number for managing resource block is also different.For example, 10MHz system bandwidths, comprising 50 RB, are divided into 17 RBG, wherein first 16
RBG respectively includes 3 RB, and last RBG then only includes 2 RB.
And include 4 PRB for the system with a width of 20MHz, including 100 PRB, each RBG.

The rule determination provided in the type1 either embodiment of the present invention.
Fig. 5 is a kind of reference of embodiment of resource allocation in uplink resource allocating method provided in an embodiment of the present invention
Figure.
In the embodiment shown in fig. 5, system bandwidth is 100 PRB, and a RBG includes 4 PRB, is divided into 25 altogether
RBG, numbering are 0 to 24.
, can be by the configured information field bit in resource allocation field in DCI with bitmap bitmap in above-mentioned resource
Mode indicate to distribute to some UE specific PRB.With the value distinguishing of different bits in the configured information field bit
Whether resource block distributes to respective user equipment corresponding to the bit.
For example, in the embodiment shown in fig. 5, numbering is that two RBG of s0=1 and S2=23 are allocated to a user
Terminal, also, in the RBG of S0=1, the 1st and the 3rd PRB is assigned to user equipment A, and the 2nd and the 4th PRB may
It is assigned to other users equipment.
For example, distributing N number of PRB with a cluster, RBG number is P, then can be come using N number of bit bitmap
The distribution condition of N number of PRB in the PRB that the RBG and subsequent one of instruction s0 and s1 marks or multiple RBG are included, withNo. RBG of a user terminal is distributed in individual bit instructions,Expression rounds up.
In the example as shown in fig. 5, represent to distribute to the cluster of user equipment with S0=00001 and S2=10111, with
1010 represent that first and the 3rd PRB is assigned to user equipment A in s0.
In S2, with 0110, that represent to distribute to user equipment A is the 2nd and the 3rd PRB.
User equipment can obtain resource according to the field bit in DCI resource allocation field.
Shown in Fig. 6 is the reference chart of another resource allocation methods with a width of 50 PRB.In Fig. 6, a RBG is only
Comprising 3 PRB, bandwidth also only includes 17 RBG, and wherein last RBG only includes 2 PRB.
Similarly, or with a cluster N number of PRB is distributed, RBG number is P, then can use N number of bit's
Bitmap indicates the distribution feelings of N number of PRB in PRB that the RBG of s0 and s1 marks and subsequent one or multiple RBG are included
Condition, withNo. RBG of a user terminal is distributed in individual bit instructions,Expression rounds up.
Therefore it is presumed that exemplified by distributing to user equipment A cluster cluster as S0=1 and S2=15.S0 is in DCI resources
It is encoded to 00001, S2 in distribution domain and is encoded to S2=01111. first PRB in S0 and be assigned to user equipment A, then encodes
User equipment A is assigned to for preceding 2 PRB in 100, S2, then is encoded to 110.
User equipment, according to decoding rule set in advance, can obtain according to the field bit in DCI resource allocation field
Resource.
In the foregoing embodiments, s2 and s3 can also be reinterpreted, identified with the RBG of s2 and s3 instructions

In the embodiment shown in fig. 7, be with the resource block group for being assigned to a user equipment especially by length
The mode of degree instruction indicates to be assigned at least one resource block of the user equipment.
It is similar with previous embodiment, need also exist for first distinguishing each RBG number, such as with S0=0001 and S2=
User equipment B resource is distributed in 10111 instructions, and to organize RBG soon be the 1st and No. 23 RBG.
In the RBG of S1 instructions, only the 1st is assigned to user equipment B, then represents to distribute to user equipment B with 00
PRB length be 1.And in the RBG indicated by S2=10111, there is the continuous 1st, 2,3 PRB to be assigned to user equipment B,
10 are then encoded to, it is 3 to represent the PRB length for distributing to user equipment B.In addition it is also possible that being indicated using a bit, at one
The PRB that a user equipment is allocated in RBG is left-justify or Right Aligns, and the embodiment shown in Fig. 7 is left-justify, also
It is that several continuous PRB that the left side is risen are allocated to a user equipment.
If a cluster is allowed to distribute N number of PRB, then can useIndividual bit bitmap is indicated
The distribution condition of N number of PRB in the PRB that the RBG and subsequent one of s0 and s1 marks or multiple RBG are included.
User equipment B, according to the instruction of respective field position in DCI, distinguishes eNodeB and distributed to certainly after DCI is received
The resource of body.
Fig. 8 is exemplified by with a width of 50 PRB, and RBG sizes are 3, are divided into 17 RBG.So s1 and s3 uses 2 bit
Length value indicate the RB distribution conditions in RBG.
If a cluster is allowed to distribute N number of PRB, then can useIndividual bit bitmap is indicated
The distribution condition of N number of PRB in the PRB that the RBG and subsequent one of s0 and s1 marks or multiple RBG are included.
For example, assuming that exemplified by distributing to user equipment C cluster cluster as S0=1 and S2=15.S0 is in DCI resources point
Be encoded in domain 00001, S2 be encoded to S2=01111. in S0 only have first PRB be assigned to user equipment A, then compile
Code 00, represent that only having first PRB to be assigned to 3 PRB in user equipment C, S2 is all assigned to user equipment C, then encodes
For 10.
In addition it is also possible that being indicated using a bit, the PRB that a user equipment is allocated in a RBG is left right
Neat or Right Aligns, the embodiment shown in Fig. 8 be left-justify, that is, several continuous PRB on the left side are allocated to one
User equipment.
