It should be pointed out that frequency domain resource distribution instructions field can be used for indicating distributing in N number of unit to user terminal Each unit, alternatively, be used to indicate in N number of unit to user terminal distribute unit in end unit and unit number, This is also feasible.

Detailed illustration is carried out to the specific implementation process of the embodiment of the present invention below.

Currently, resource allocation type 1 with resource block group (Resource Block Group, RGB) be unit, by bandwidth portion (Band Width Part, BWP) is divided to be divided into N_RBGA RBG, the resource allocation granularity of resource allocation type 1 are a resource Block (Resource Block, RB).

Wherein, N_RBGTo following formula can be used to obtain:

Wherein,For the size of BWP,It is to be given according to the size and base station of BWP for the starting CRB, P of BWP The RBG size that the configuration of terminal is determined.In general, the size of first RBG is IfThe RB number that then the last one RBG includes be Otherwise the RB number that the last one RBG includes is P.The number of remaining RBG is P.

Specifically, it is assumed that RBG is divided as shown in Fig. 2, in Fig. 2,P=2, thenThe size of remaining RBG is 2.

It should be noted that resource allocation type 1 only supports continuous virtual RB (Virtual RB, VRB), it will starting VRB number is indicated with VRB several combined codings, and the granularity of resource allocation is a RB.For resource allocation type 1 Bit number be log₂N (N+1)/2, N is the size of BWP.

Under the scene of the public search space in the scene of BWP switching and activation BWP, if occurring being used for frequency domain resource The number of bits of distribution is less than the case where number of bits actually required, if only only simply increasing of resource allocation Granularity, which may cause, to be difficult to the UE (user terminal) of different resource distribution type carrying out frequency domain multiplexing from network side.Such as it will money The granularity of source distribution type 1 increases to 2 RB (being known as VRB set in the following figure) shown in Fig. 3, then resource allocation type 1 What can be distributed is that any one VRB set starts continuous any VRB set.It can be seen that resource allocation at this time always with The boundary of RBG is misaligned, so that the UE of different resource distribution type is difficult to be multiplexed.

Similarly, if resource allocation granularity and RBG size may also cannot will lead to multiplexing difficulty by multiple proportion each other. For example, as shown in following Fig. 4, particle distribution degree is 3, if distributing even number VRB set since even number VRB set with The boundary RBG is misaligned；If distributing odd number VRB set since odd number VRB set to be also misaligned with the boundary RBG.

In view of this, the embodiment of the invention provides carry out in the case where frequency domain resource particle distribution degree is greater than 1 RB Several ways therein are carried out citing introduction below by the mode of continuous resource distribution.

Embodiment one:

Assuming that the number of bits of the frequency domain resource distribution instructions field in DCI for resource allocation type 1 is 9, i.e. B=9.BWP size For 273 RB, i.e.,Frequency domain resource particle distribution degree M is to meet Minimum positive integer, then can obtain M=9.

Next, base station can sequence in BWP according to frequency from low to high, according to frequency domain resource particle distribution degree M BWP is divided into N number of RB unit, according to formulaN=31 can be obtained.In this way, being divided to BWP When, RB unit 0 (i.e. first RB unit) includes RB0 to RB8；RB unit 1 (i.e. second RB unit) includes RB9 to RB17； And so on, RB unit 29 (i.e. the 30th RB unit) includes RB261 to RB269；(i.e. the 31st RB is mono- for RB unit 30 Member can also be referred to as the last one RB unit) it include RB270 to RB272.
