Resource allocation method and apparatus

A method for resource allocation, applied to a base station, comprising:

• transmitting resource allocation indication information to a user equipment (UE), wherein the resource allocation indication information indicates a time domain resource occupied by a forward time-frequency resource for sidelink communication in a slot and a time domain resource occupied by a reverse time-frequency resource for sidelink communication in the slot, so that the UE determines the time domain resource occupied by the forward time-frequency resource in the slot and the reverse time-frequency resource in the slot according to the resource allocation indication information,
• wherein the forward time-frequency resource transmits at least one of a physical sidelink share channel (PSSCH) or a physical sidelink control channel (PSCCH), and the reverse time-frequency resource transmits a physical sidelink feedback channel (PSFCH) from a device for receiving the user data to a device for transmitting the user data,
• wherein sequence number of a time domain symbol occupied by the forward time-frequency resource is smaller than sequence number of a time domain symbol occupied by the reverse time-frequency resource, the forward time-frequency resource occupies the time domain symbol at a front position in the slot, and the reverse time-frequency resource occupies the time domain symbol at a latter position in the slot.

An apparatus for resource allocation, comprising:

• a processor;
• memory for storing instructions executable by the processor;
• and
• a communication component;
• wherein the processor is configured to execute the instructions to:
• control the communication component to receive resource allocation indication information from a base station, wherein the resource allocation indication information indicates a time domain resource occupied by a forward time-frequency resource for sidelink communication in a slot and a time domain resource occupied by a reverse time-frequency resource for sidelink communication in the slot, the forward time-frequency resource transmits at least one of a physical sidelink share channel (PSSCH) or a physical sidelink control channel (PSCCH), and the reverse time-frequency resource transmits a physical sidelink feedback channel (PSFCH) from a device for receiving the user data to a device for transmitting the user data;
• and
• determine, according to the resource allocation indication information, the time domain resource occupied by the forward time-frequency resource in the slot and the time domain resource occupied by the reverse time-frequency resource in the slot, wherein sequence number of a time domain symbol occupied by the forward time-frequency resource is smaller than sequence number of a time domain symbol occupied by the reverse time-frequency resource, the forward time-frequency resource occupies the time domain symbol at a front position in the slot, and the reverse time-frequency resource occupies the time domain symbol at a latter position in the slot.
