Abstract

Certain aspects of the present disclosure relate to a method for generating a frame structure suitable for use in both single carrier (SC) and Orthogonal Frequency Division Multiplexing (OFDM) transmission modes, while ensuring accurate channel estimation at a receiver.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims the benefit of Provisional Application No. 61 / 103,503, filed October 7, 2008, which is assigned to the assignee of this application and is hereby expressly incorporated by reference. technical field [0003] In general, certain aspects of the invention relate to wireless communications, and in particular, to the generation of extended Golay codes and the use of different fields of packets for single carrier and Orthogonal Frequency Division Multiplexing (OFDM) transmissions . Background technique [0004] Millimeter wave communication means communication using a carrier frequency of about 60 GHz. The dual-mode mmWave physical layer (PHY) can support single-carrier (SC) modulation and orthogonal frequency-division multiplexing (OFDM) modulation by employing common-mode (CM) transmission. [0005] CM denotes the single carrier mode used by both SC and OFDM based devices for beaconing, ne...
