Method and apparatus for resource allocation

Abstract

The present application discloses a method for resource allocation, including: a network device determines a set including at least two groups of patterns according to the maximum number of transmissions of a terminal within a scheduling period, wherein any set of patterns in the set is the same as any other set of patterns The group pattern corresponds to at most K identical first subframes; the network device receives resource scheduling request messages sent by at least two terminals; the network device determines the target pattern group from the set according to the resource scheduling request message, and the target pattern group is related to at least two The terminals are in one-to-one correspondence; the network equipment respectively sends the information of the target pattern group to at least two of the terminals. It can reduce the conflict between terminals and improve the success rate of information transmission. The solution provided in this embodiment can be applied to communication systems, such as V2X, LTE-V, V2V, Internet of Vehicles, MTC, IoT, LTE-M, M2M, Internet of Things, etc. The solution provided in this embodiment can also improve the automatic driving or assisted driving ability of the car.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method and equipment. Background technique [0002] Vehicle Direct Communication (VDC) refers to direct communication between vehicles through mobile communication devices, such as mutual transmission of vehicle speed, position, driving direction, braking and other information. [0003] During the movement of the vehicle terminal (Vehicle User Equipment, VUE), according to the driving speed, acceleration, direction and other information, the size and period of the data packet for transmitting safety assistance messages between vehicles changes dynamically. Therefore, in order to reduce the transmission delay of data packets and ensure the performance of Packet Delivery Ratio (PDR) of data packets, the base station needs to dynamically and flexibly schedule time-frequency resources according to different data packet sizes. [0004] At present, the device-to...

Problems solved by technology

[0004] At present, the device-to-device (D2D) communication of the Long Term Evolution (LTE) system supports few users. There are serious half-duplex conflicts in the domain and co-channel interference in the frequency domain, and there are serious interference problems caused by In Band Emission (IBE)
