Embodiment 1

[0060] This embodiment is a resource allocation in M-bit, with 2 M Codewords indicate different resources for resource allocation.

[0061] The bandwidth of BWP I is 20 RBs, M. The method of the m is as follows: M The default value is 4; m is configured to 4 by high-level signaling, and the X is configured to be 2 or the default value 2 is configured by the high-level signaling. ,

[0062] 20 VRB points 2 4-1 = 8 frequency domain units, frequency domain units 0, 1, 2, 3 contain three VRBs, and frequency domain units 4, 5, 6, 7 include two VRBs, as shown in the following table:

[0063]

[0064] The fixed value of the α is 0.75 or by high-level signaling is configured to 0.75, L = 6.

[0065] With 4 bits, you can indicate 16 resource allocation methods, and the specific steps of encoding are as follows:

[0066] K The value range is 1, 2, 3, 4.

[0067] 1.K is 1, with 8 codewords to indicate each frequency domain unit. If the code 00000 indicates the frequency domain unit 0.

Embodiment 2

[0076] The bandwidth of BWP I is 20 RBs, m = 4, and M.

[0077] The entire BWP frequency domain unit is divided into two parts, and the frequency domain unit [0, 3] belongs to the first portion, and the frequency domain unit [4, 7] belongs to the second portion.

[0078] With 3 bits to encode, you can indicate that 8 resource allocation methods, the specific steps of encoding are as follows:

[0079] K 's value range is 1, 2, 3.

[0080] 1, K is 1, MOD (K, 2) is 1, 2 2 The code word is indicated to each frequency domain unit of the first part. If the code 000 indicates the frequency domain unit 0;

[0081] 2, K is 2, MOD (K, 2) is 0, use 2 1 The code word is indicated to each 2 consecutive frequency domain units of the second part. If the code word 100 indicates the frequency domain units 4 and 5;

[0082] 3, when K is 3, the mod (k, 2) is 1, and each 4 consecutive frequency domain units of the first portion are indicated by 1 codeword. If the codeword 110 indicates the frequency ...

Abstract

The present invention provides a frequency domain resource allocation method, device, equipment, and wireless communication system, aiming at the 5G NR system standard, it can be used for URLLC services, and different resources are indicated to make full use of the bits used for frequency domain resource allocation in DCI Divide the bandwidth of the entire part of the carrier bandwidth into multiple frequency domain resources as evenly as possible, and indicate each and every continuous multiple frequency domain resources, or for each and every continuous frequency domain resource in a certain frequency domain unit part A plurality of frequency domain resources are used to indicate, and the frequency domain resource allocation method can be specifically adapted to the 5G NR standard. Compared with the prior art that cannot fully use the number of bits used for resource allocation, the present invention makes full use of the Based on the number of bits allocated for frequency domain resources, a relatively small number of bits is used for resource allocation, reducing the total number of bits of downlink control information, thereby improving the success rate of decoding downlink control information, and realizing a highly reliable and efficient resource allocation.

Description

Technical field [0001] The present invention relates to the field of wireless communication technologies, and more particularly to a frequency domain resource allocation method under 5G NR protocol standards and a device and system corresponding to the method. Background technique [0002] URLLC (Ultra-Reliable and Latency Communications), a 5G application scenario defined by the 3GPP (3rd Generation Partnership Project, the Third Generation Partner Program). The URLLC service has burst, sparse, and a smaller feature of the data package and the URLLC business has a very strict requirement for delay and reliability. The URLLC service control channel also has a very strict requirement, NR (New Radio, new air) supports simplified DCI (DownLink Control Information, downlink control information) to achieve high reliability. This simplified DCI needs to reduce the number of bits indicating information such as resource allocation, MCS. [0003] At present, NR supports two resource alloc...
