Resource allocation method and device

A resource allocation device, wherein the device comprises:

• a processor, configured to determine, based on a maximum quantity of transmissions of a terminal device in a scheduling period, a set comprising at least two groups of patterns, wherein the set is corresponding to a time-frequency resource pool, the time-frequency resource pool comprises N subframes, each group of patterns are in a one-to-one correspondence with the N subframes, a quantity of first subframes comprised in each group of patterns is the same as the maximum quantity of transmissions, the first subframe is a subframe to which a frequency domain resource is allocated, and any group of patterns and any other group of patterns in the set are corresponding to a maximum of K same first subframes, wherein N and K are integers, N≥2, and K is greater than or equal to 0 and is less than the maximum quantity of transmissions;
• a receiver, configured to receive resource scheduling request messages sent by at least two terminal devices, wherein the resource scheduling request message is used to request the network-side device to allocate a time-frequency resource to a terminal device corresponding to the resource scheduling request message, and the time-frequency resource is used by the terminal device to perform broadcast communication, wherein
• the processor is further configured to determine a target group of patterns from the set based on the resource scheduling request messages received by the receiver, wherein the target group of patterns are in a one-to-one correspondence with the at least two terminal devices, and a quantity of the first subframes corresponding to the target group of patterns is equal to a maximum quantity of transmissions of the at least two terminal devices;
• and
• a transmitter, configured to separately send information about the target group of patterns determined by the processor to the at least two terminal devices.

A non-transitory computer-readable storage medium that stores instructions, wherein the instructions make a method executed, the method comprises:

• determining, by a network-side device based on a maximum quantity of transmissions of a terminal device in a scheduling period, a set comprising at least two groups of patterns, wherein the set is corresponding to a time-frequency resource pool, the time-frequency resource pool comprises N subframes, each group of patterns are in a one-to-one correspondence with the N subframes, a quantity of first subframes corresponding to each group of patterns is the same as the maximum quantity of transmissions, the first subframe is a subframe to which a frequency domain resource is allocated, and any group of patterns and any other group of patterns in the set are corresponding to a maximum of K same first subframes, wherein N and K are integers, N≥2, and K is greater than or equal to 0 and is less than the maximum quantity of transmissions;
• receiving, by the network-side device, resource scheduling request messages sent by at least two terminal devices, wherein the resource scheduling request message is used to request the network-side device to allocate a time-frequency resource to a terminal device corresponding to the resource scheduling request message, and the time-frequency resource is used by the at least two terminal devices to perform broadcast communication;
• determining, by the network-side device, a target group of patterns from the set based on the resource scheduling request messages, wherein the target group of patterns are in a one-to-one correspondence with the at least two terminal devices, and a quantity of the first subframes corresponding to the target group of patterns is equal to a maximum quantity of transmissions of the at least two terminal devices, and
• separately sending, by the network-side device, information about the target group of patterns to the at least two terminal devices.
