Method and device for resource allocation and sidelink communication

A resource allocation method, comprises the following steps of:

• sensing each configured resource pool to obtain a result of sensing, the result of sensing containing a set of remaining single time unit (TU) resources of each resource pool;
• selecting, from the set of remaining candidate single TU resources of each resource pool, one candidate single TU resource as a transmission resource;
• and
• transmitting, via the transmission resource, a packet to be transmitted which is borne by the transmission resource;
• wherein the candidate single TU resource is a time-frequency resource which consists of N TU s and M Physical resource blocks (PRBs) and is used for transmitting a same packet, where N>1 and M≥1.

A user equipment, comprises:

• a first processing unit configured to sense each configured resource pool to obtain a result of sensing, the result of sensing containing a set of remaining candidate single TU resources of each resource pool;
• a second processing unit configured to select, from the set of remaining candidate single TU resources of each resource pool, one candidate single TU resource as a transmission resource;
• and
• a transmitting unit configured to transmit, via the transmission resource, a packet to be transmitted which is borne by the transmission resource;
• wherein the candidate single TU resource is a time-frequency resource which consists of N TUs and M PRBs and is used for transmitting a same packet, where N>1 and M≥1.
