1. A method for communications, comprising:
determining, at a first terminal device, at least one sub-channel based on a size of
data to be transmitted, each sub-channel comprising at least one frequency interlace; and
transmitting, to a second terminal device, the data and control information
associated with the data on the at least one sub-channel via a sidelink between the first
terminal device and the second terminal device.
2. The method of claim 1, wherein the number of the at least one frequency interlace
is configured or pre-configured.
3. The method of claim 1, further comprising:
determining the number of the at least one frequency interlace based on a size of
resources in frequency domain for transmitting the control information.
4. The method of claim 1, wherein each sub-channel compnses a plurality of
consecutive frequency interlaces.
5. The method of claim 4, wherein the number of the consecutive frequency
interlaces is configured by a higher layer or is derived from a resource size for the control
information in frequency domain.
6. The method of claim 1, wherein each sub-channel compnses a plurality of
non-consecutive frequency interlaces.
7. The method of claim 6, wherein a gap among the non-consecutive frequency
interlaces is configured by a higher layer or pre-configured.
8. The method of claim l, wherein each sub-channel comprises the at least one
frequency interlace in a single Resource Block (RB) set.
9. The method of claim 8, wherein determining the at least one sub-channel
compnses:
