Resource allocation method and device

This is a National Stage Application, filed under U.S.C. 371, of International Application No. PCT/CN2019/074853 filed on Feb. 12, 2019, which claims priority to Chinese patent application No. 201810147407.5 filed on Feb. 12, 2018, disclosure of which i& are incorporated herein by reference in their entirety.

The present disclosure relates to the field of wireless communication technology, for example, to a resource allocation method and device.

Machine Type Communications (MTC), also referred to as Machine to Machine (M2M) Communications, is the primary application mode of the Internet of Things in the current stage. Currently, MTC devices deployed on the market are mainly based on the Global System of Mobile communication (GSM). In recent years, more and more mobile operators choose Long Term Evolution/Advanced Long-Term Evolution (LTE/LTE-A) as the evolution direction of the future broadband wireless communication system due to the high spectral efficiency of the LTE/LTE-A. MTC multi-type data services based on LTE/LTE-A will also be more attractive.

A minimum resource allocation granularity of the resource allocation of a Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH) of a related MTC terminal (Rel-13 (version 13) MTC terminal) is one Physical Resource Block (PRB), where one physical resource block is formed by 12 subcarriers in frequency domain. The overhead of a PUSCH resource allocation field in a coverage enhancement mode A (CE mode A) is

⌈ log 2 ( ⌊ N RB UL 6 ⌋ ) ⌉ + 5

bits, where N RB UL is the number of uplink physical resource blocks. The overhead of the PDSCH resource allocation field is

⌈ log 2 ( ⌊ N RB DL 6 ⌋ ) ⌉ + 5 ,

where N RB DL is the number of downlink physical resource blocks; the overhead of the PUSCH resource allocation field in a coverage enhancement mode B (CE mode B) is

⌈ log 2 ( ⌊ N RB UL 6 ⌋ ) ⌉ + 3

bits, and the overhead of the PDSCH resource allocation field is

⌈ log 2 ( ⌊ N RB DL 6 ⌋ ) ⌉ + 1.

Such resource allocation method can only be performed within a narrowband, and since the traditional LTE resource allocation is performed according to the resource block groups, the size of a resource block group (RBG) (the RBG includes 2 PRBs for a 3/5 MHz system bandwidth; the RBG includes 3 PRBs for a 10 MHz system bandwidth, the RBG includes 4 PRBs for a 15/20 MHz system bandwidth) and the size of a narrowband (6 PRBs) are inconsistent, causing that the edge of the narrowband may not be aligned with the RBG, some PRBs may not be allocated, and leading to resource allocation fragmentation. As shown in FIG. 1 , taking the system bandwidth with 3 MHz as an example, one RBG includes 2 consecutive PRBs, and one narrowband includes 6 consecutive PRBs. If narrowband 0 has been allocated to the terminal, then PRB 0 and PRB 7 may no longer be allocated to the terminal, leading to resource allocation fragmentation.

At present, there is no solution for reducing the resource allocation fragmentation.

The present application provides a resource allocation method and device, which can implement a more flexible narrowband resource allocation strategy, thereby improving the resource allocation flexibility of narrowband user equipment.

The embodiment of the present disclosure provides a resource allocation method, including steps described below.

Resource position indication information is sent, where the resource position indication information carries position information of a physical resource block (PRB) resource within a narrowband and shift offset information of the PRB resource within the narrowband, or the resource position indication information carries position information of a PRB resource within the narrowband and position information of a PRB resource out of the narrowband.

The embodiment of the present disclosure provides a resource allocation device, including an information sending module and a resource allocation module.

The information sending module is configured to send resource position indication information, wherein the resource position indication information carries position information of a physical resource block (PRB) resource within a narrowband and shift offset information of the PRB resource within the narrowband, or the resource position indication information carries position information of a PRB resource out of the narrowband and the position information of the PRB resource within the narrowband.

The resource allocation module is configured to determine a position of an actually allocated resource according to the position information of the PRB resource within the narrowband carried in the resource position indication information and the shift offset information of the PRB resource within the narrowband carried in the resource position indication information; or determine a position of an actually allocated resource according to position information of the PRB resource within the narrowband and the position information of the PRB resource out of the narrowband carried in the resource position indication information.

The embodiment of the present disclosure provides a resource allocation device, which includes: a memory, a processor and a resource allocation program stored in the memory and executable on the processor, where the resource allocation program, when executed by the processor, implements the resource allocation method described above.

The embodiment of the present application provides a computer-readable storing a resource allocation program, wherein the resource allocation program, when executed by a processor, implements the resource allocation method described above.
