Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for CRC scrambling for SCI in sidelink communication. A wireless transmitter may be configured to scramble bits of SCI based on a scrambling sequence and transmit the SCI to a wireless receiver. The wireless receiver may receive the SCI having CRC bits scrambled with the scrambling sequence and attempt to decode the SCI, including descrambling the CRC bits of the SCI. The SCI may include a first portion of SCI transmitted in a PSCCH and a second portion of SCI transmitted in a PSSCH.
Claims30
An apparatus for wireless communication at a wireless transmitter, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- scramble cyclic redundancy check (CRC) bits of sidelink control information (SCI) based on a scrambling sequence;
- and
- transmit the SCI, the SCI includes a first portion of the SCI transmitted in a physical sidelink control channel (PSCCH) and a second portion of the SCI transmitted in a physical sidelink shared channel (PSSCH), wherein the wireless transmitter scrambles the CRC bits of at least one of the first portion of the SCI or the second portion of the SCI based on the scrambling sequence.
An apparatus for wireless communication at a wireless receiver, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive sidelink control information (SCI) having cyclic redundancy check (CRC) bits scrambled with a scrambling sequence;
- and
- attempt to decode the SCI including descrambling the CRC bits of the SCI, the SCI including a first portion of the SCI received in a physical sidelink control channel (PSCCH) and a second portion of the SCI received in a physical sidelink shared channel (PSSCH), the wireless receiver descrambles the CRC bits of at least one of the first portion of the SCI or the second portion of the SCI based on the scrambling sequence.
