Abstract

Methods for the transmission of SCI messages in sidelink communications for the reservation of resources. The modulation and coding scheme of a second stage SCI may be indicated in the first stage SCI.

Claims (16)

1. A method for transmission of scheduling and control information for sidelink communications, the method comprising steps performed at a mobile device of:

receiving and decoding a first stage Sidelink Control Information (SCI) carrying scheduling information,

receiving a second stage SCI indicated by the first stage SCI, and

decoding the second stage SCI at an intended receiver,

wherein the second stage SCI uses lower order modulation including Quadrature Phase Shift Keying (QPSK),

wherein the coded bits of the second stage SCI are mapped from a lowest physical resource block (PRB) locations in the scheduled resource for Physical Sidelink Shared Channel (PSSCH), and

wherein a modulation and coding scheme for the second stage SCI is indicated in the first stage SCI as a row index for a mapping table comprising modulation and coding schemes values for the second stage SCI.

2. A method according to claim 1 , a modulation and coding scheme for the first stage SCI is indicated as part of the resource pool configuration.

3. A method according to claim 1 , wherein

the first stage SCI indicates the SCI of the associated second stage SCI.

4. A method according to claim 1 , wherein

the mapping of the second stage SCI in PSSCH starts from a front-loaded demodulation reference symbol DMRS symbol over unused resource elements.

5. A method according to claim 1 , wherein

the first stage SCI indicates a modulation and coding scheme of the associated second stage SCI.

6. A method according to claim 1 , further comprising

a step of identifying from the scheduling information in the first stage SCI if the mobile device is the intended receiver of the second stage SCI.
