US 8,413,001 B2 · Determining hybrid automatic repeat request (HARQ) timing

Abstract

A communication apparatus (CA) such as a mobile node/station (MN), a base station (BS), or a radio station (RS) may support determination of HARQ timing. The CA may generate at least in part one or more generalized frames such as a frequency division duplex (FDD) frame or a time division duplex (TDD) frame. The generalized FDD and TDD frames may include support to determine the HARQ timing considering various factors, which may affect the HARQ timing. The FDD and TDD frames may include information corresponding to various factors to determine the HARQ timing considering factors such as DL/UL ratio, number of sub-frames per frame, variable transmission time interval (TTI), relay zones, legacy IEEE® 802.16e zones, and availability of ACKCH.

Dependent claims

A communication apparatus to determine hybrid automatic repeat request (HARQ) timing, comprising:

a transmitter coupled to a transmit portion of a channel,
a receiver coupled to a receive portion of the channel, and
a hybrid automatic repeat request (HARQ) logic coupled to the transmitter and the receiver,
wherein the HARQ logic is to determine HARQ timing after considering a plurality of factors, which affect HARQ timing,
wherein the HARQ logic is to generate one or more super-frames according to a generalized frame structure in which the plurality of factors affecting the HARQ timing are included to determine a unified HARQ timing, each of the one or more super-frames comprising one or more frames.
