Claim of US Patent No. 10,251,192

1. A scheduling assignment (SA) indicating method used by device-to-device (D2D)-enabled wireless devices communicating with each other via multiple SA periods, each SA period including a SA pool and a data pool, wherein the SA pool is used for transmitting SAs for assigning data resources of the data pool, the method comprising:selecting SA resources in SA pools of more SA periods to transmit SAs for assigning the same data resources for a D2D-enabled wireless device;
transmitting the SAs using the selected SA resources; and
using reserved SA resources to perform one of (i) repetitively transmitting the SAs of other D2D-enabled wireless devices and (ii) transmitting the SAs of other D2D-enabled wireless devices to assign new data resources, wherein the reserved SA resources are the SA resources linked to the same data resource pattern of unselected SA periods as the data resource pattern of the selected SA periods.
