Abstract
A user equipment (UE) is configured to receive configuration information for a sidelink connection in an unlicensed frequency band, the configuration information comprising a first bitmap comprising an indication of resource block (RB) sets with available Physical Sidelink Feedback Channel (PSFCH) resources and transmit PSFCH information based on the configuration information.
Claims20
A method performed by a user equipment (UE), comprising:
- receiving configuration information for a sidelink connection in an unlicensed frequency band, the configuration information comprising a first bitmap comprising an indication of resource block (RB) sets with available Physical Sidelink Feedback Channel (PSFCH) resources;
- and
- transmitting PSFCH information based on the configuration information.
A method performed by a user equipment (UE) communicating on a sidelink connection in an unlicensed frequency band, comprising:
- receiving a Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH) transmission;
- determining a slot and a starting interlace index that the PSCCH or PSSCH transmission was received;
- and
- determining Physical Sidelink Feedback Channel (PSFCH) resources corresponding to the PSCCH and PSSCH transmission, wherein the determining is based on the slot and starting interlace index.
