Scheduling assignment content and transmission in wireless communications
First Claim
1. A method of wireless communications, comprising:
- determining a first resource block within a first subframe of a scheduling assignment (SA) resource pool for transmitting an SA, the SA indicating resources for a subsequent transmission of data to one or more devices;
transmitting the SA to the one or more devices during the first resource block; and
retransmitting, independent of feedback for the SA transmission and before the subsequent transmission of data, the SA during a second resource block within a second subframe of the same SA resource pool according to a predetermined retransmission pattern such that a position of the second resource block within the second subframe is different from and based at least in part on a position of the first resource block within the first subframe.

Abstract
Methods, systems, and devices are described for transmissions and retransmissions of scheduling assignment (SA) information, and for content of SA transmissions. SAs may be transmitted during an initial communications period, followed by data transmissions for a certain time period. A device may monitor for transmissions during the SA period and then monitor for data transmissions during periods indicated in a received SA. SAs may be retransmitted according to a retransmission pattern that may provide time or frequency diversity patterns in order to enhance reception of SAs at a receiving device. Retransmission patterns may be determined based on a resource from an SA resource pool that is used for an initial transmission of the SA.
