Abstract
The described techniques may support multi-rank sidelink communications that may be reduced to single rank communications if failure to decode the multi-rank sidelink communications occurs. A user equipment (UE) may transmit a first message including first data using a first precoding vector applied for a first layer and a second precoding vector applied for a second layer. If the first message is not decoded successfully, the UE may transmit a second message including second data using a third precoding vector applied for the first layer and a fourth precoding vector applied for the second layer, where the second data is derived from the first data, the third precoding vector is derived from the second precoding vector, and the fourth precoding vector is derived from the first precoding vector. The second message may effectively reduce a rank of the first message when the channel is rank deficient.
