6. The transmitting apparatus according to claim 1 , wherein in a case that the common resource allocation reference is configured based on receiving apparatus resources and the receiving apparatus is configured with multiple receiving resource pools, a superset of multiple receiving resource pools of the receiving apparatus is used as the common resource allocation reference.
7. The transmitting apparatus according to claim 1 , wherein a superset of one or more transmitting resource pools and one or more receiving resource pools of the transmitting apparatus is used as the common resource allocation reference.
8. The transmitting apparatus according to claim 1 , wherein in a case that the common resource allocation reference is configured based on receiving apparatus resources, a superset of one or more transmitting resource pools and one or more receiving resource pools of the receiving apparatus is used as the common resource allocation reference.
9. The transmitting apparatus according to claim 1 , wherein in a case that a receiving resource pool for receiving PSCCH and PSSCH are separate, the receiving resource pool for receiving PSSCH of the transmitting apparatus is used as the common resource allocation reference.
10. The transmitting apparatus according to claim 1 ,
wherein the SCI indicates a field of the common resource allocation reference and a field of resource allocation, and
wherein the field of resource allocation indicates allocated Physical Resource Blocks (PRB) within the common resource allocation reference.
11. The transmitting apparatus according to claim 1 , wherein a control resource set or a resource pool of the PSCCH is used as the common resource allocation reference for the PSSCH.
12. The transmitting apparatus according to claim 1 , wherein a base station allocates resources for a Physical Downlink Shared Channel (PDSCH) based on the common resource allocation reference.
13. The transmitting apparatus according to claim 1 , wherein there is a resource pool, and the resource pool is used by the transmitting apparatus to allocate resources for the PSSCH and is used by the receiving apparatus to obtain the allocated resources, and wherein the resource pool is used as the common resource allocation reference.
14. A receiving apparatus, comprising:
a receiver, operative to receive a common resource allocation reference on Sidelink Control Information (SCI) transmitted in a Physical Sidelink Control Channel (PSCCH); and
circuitry, operative to obtain an allocated resource for a Physical Sidelink Shared Channel (PSSCH) based on the common resource allocation reference which is used by a transmitting apparatus for transmitting PSSCH on the allocate resources,
wherein in a case that the common resource allocation reference is configured based on transmitting apparatus resources and the transmitting apparatus is configured with multiple non-contiguous receiving resource pools in a frequency domain, the common resource allocation reference is a superset including the multiple non-contiguous receiving resource pools and intervening resources between the multiple non-contiguous receiving resource pools.
15. A wireless communication method for a transmitting apparatus, comprising:
allocating resources for a Physical Sidelink Shared Channel (PSSCH) based on a common resource allocation reference which is used by a receiving apparatus to obtain the allocated resources and indicating the common resource allocation reference via Sidelink Control Information (SCI) transmitted in a Physical Sidelink Control Channel (PSCCH); and
transmitting the common resource allocation reference to the receiving apparatus via the PSCCH,
wherein in a case that the common resource allocation reference is configured based on transmitting apparatus resources and the transmitting apparatus is configured with multiple non-contiguous receiving resource pools in a frequency domain, the common resource allocation reference is a superset including the multiple non-contiguous receiving resource pools and intervening resources between the multiple non-contiguous receiving resource pools.
