Problems solved by technology

[0006] However, since the source allocation is based on the D2D-enabled wireless device's own selection, if the D2D-enabled wireless device loses the assignment signaling (for example, sends the assignment signaling in SA period #1 to indicate figure 1 data resources in all 5 SA cycles in the SA cycle), SA and / or data transmissions may collide

Abstract

A scheduling assignment indication method and a device-to-device (D2D) enabled wireless device. The method is used by D2D-enabled wireless devices communicating with each other via a plurality of SA periods, each of which includes an SA pool and a data pool, wherein the SA pool is used to send a data pool allocation The SA of the data resources, the method includes: selecting the SA resources in the SA pool of the SA cycle of multiple SAs and assigning the SA of the same data resources to the D2D-enabled wireless device. The SA indication method and the D2D-enabled wireless device can increase the capacity of the SA pool, avoid SA and / or data transmission conflicts, and enhance the robustness of SA transmission.

Description

technical field [0001] The present disclosure relates to a method for indicating scheduling assignment in device-to-device wireless communication, and a D2D-enabled wireless device using the method. Background technique [0002] Device-to-device (D2D) is direct communication between devices, which can occur within network coverage (e.g. for commercial situations) or without network coverage (e.g. for public safety situations) . [0003] In device-to-device communication, the communication system contains multiple D2D-enabled wireless devices, and these D2D-enabled wireless devices communicate via several consecutive scheduling assignment (SA) cycles, each SA cycle includes SA pool and data pool . The SA pool of the SA period is used to send SAs for allocating data resources of the data pool of the SA period for the same or different D2D-enabled wireless devices. [0004] figure 1 It is shown that the SA pool of SA periods is used to transmit SAs that allocate data resour...
