Embodiment 1

[0307] Assume that the number of bits in the frequency domain resource allocation indication field for resource allocation type 1 in the DCI is 9, that is, B=9. The BWP size is 273 RBs, ie Frequency domain resource allocation granularity M is to satisfy The smallest positive integer of , then M=9 can be obtained.

[0308] Next, the base station can divide the BWP into N RB units according to the frequency domain resource allocation granularity M in order of frequency from low to high in the BWP, according to the formula N=31 can be obtained. In this way, when dividing the BWP, RB unit 0 (that is, the first RB unit) includes RB0 to RB8; RB unit 1 (that is, the second RB unit) includes RB9 to RB17; and so on, RB unit 29 (that is, The 30th RB unit) includes RB261 to RB269; the RB unit 30 (that is, the 31st RB unit, which may also be referred to as the last RB unit) includes RB270 to RB272.

[0309] Assuming that the base station allocates RB unit 29 and RB unit 30 to the u...

Embodiment 2

[0312] Assume that the number of bits in the frequency domain resource allocation indication field for resource allocation type 1 in the DCI is 9, that is, B=9. The BWP size is 273 RBs, ie Frequency domain resource allocation granularity M is to satisfy The smallest positive integer of , then M=9 can be obtained.

[0313] Next, the base station may divide the BWP into N RB units according to the frequency-domain resource allocation granularity M in the order of frequencies from low to high in the BWP. According to the formula N=30 can be obtained.

[0314] In a case of dividing the BWP, RB unit 0 (that is, the first RB unit) includes RB0 to RB8; RB unit 1 (that is, the second RB unit) includes RB9 to RB17; and so on, RB unit 29 (that is, the thirtieth RB unit, which may also be referred to as the last RB unit) includes RB261 to RB269. It can be seen that in this case, the If it is not an integer multiple of M, some RBs in the BWP may not be divided into RB units.

Embodiment 3

[0319] Assume that the number of bits in the frequency domain resource allocation indication field for resource allocation type 1 in the DCI is 9, that is, B=9. The BWP size is 273 RBs, ie Frequency domain resource allocation granularity M is to satisfy

[0320] And it is the smallest positive integer to the power of 2, M=16 can be obtained.

[0321] Next, the base station can divide the BWP into N RB units according to the frequency-domain resource allocation granularity M in the order of frequencies from low to high in the BWP, N=18 units are available. In this way, when dividing the BWP, the number of RBs contained in RB unit 0 (that is, the first RB unit) is That is, it includes RB0 to RB7; the number of RBs included in RB unit 17 (ie, the last RB unit) is 1, including RB264 to RB272; other RB units include 16 RBs.

[0322] Assuming that the base station allocates RB unit 0 and RB unit 1 to the user terminal, then the frequency domain resource allocation indicat...

Abstract

The embodiment of the invention provides a resource allocation indication method, a resource allocation acquisition method, a base station and a user terminal. The resource allocation indication method is applied to the base station, and comprises the following steps: determining frequency domain resource allocation granularity; wherein the frequency domain resource allocation granularity is greater than one resource block RB; dividing the BWP according to the size of the bandwidth part BWP and the frequency domain resource allocation granularity to obtain N units; sending scheduling information to the user terminal; wherein the scheduling information comprises a frequency domain resource allocation indication domain, and the frequency domain resource allocation indication domain is used for indicating a unit allocated to the user terminal in the N units. According to the embodiment of the invention, the resource utilization rate can be well ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a resource allocation indication method, a resource allocation acquisition method, a base station and a user terminal. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as the International Telecommunication Union (International Telecommunication Union, ITU) have begun to study new wireless communication systems (ie, 5G NR, 5Generation New RAT). [0003] Currently, NR supports two frequency domain resource allocation types, which are called resource allocation type 0 and resource allocation type 1 respectively. Among them, the resource allocation type 1 uses the resource block group (Resource Block Group, RGB) as the unit, and divides the bandwidth part (Band Width Part, BWP) into N RBG RBG, and the resource allocation granularity of resource allocation type 1 is one resource blo...
