Multicarrier retransmission feedback

摘要

Systems and methodologies are described that facilitate indicating feedback parameters for multiple single carrier assignments, multicarrier assignments, and/or the like according to single carrier-frequency division multiple access (SC-FDMA), relaxed SC-FDMA, etc. Feedback in relaxed SC-FDMA can be bundled by a mobile device to conserve power. In addition, a downlink assignment indicator (DAI) can be utilized to detect and indicate lost grants.

主权项

1. A method, comprising:
receiving a plurality of downlink resource grants related to a plurality of carriers for data transmission; obtaining a downlink assignment index (DAI) related to each of the plurality of downlink resource grants; and determining one or more lost downlink resource grants based at least in part on the DAI related to each of the plurality of downlink resource grants, wherein the determining one or more lost downlink resource grants includes: determining a total number of resource grants transmitted by an access point from the DAI; and performing one or more comparison operations based on a total number of the plurality of downlink resource grants and the total number of resource grants transmitted by the access point; and wherein the total number of resource grants refers to the total number of resource grants across the plurality of carriers in a given subframe or the total number of resource grants across the plurality of carriers and a plurality of subframes.
