Abstract

Certain aspects of the present invention relate to a method for allocating a plurality of logical channels within each wideband channel specified by the IEEE 802.15.3c standard. Each logical channel can utilize the same wideband channel, but the logical channel can also utilize a narrowband channel (i.e., a low data rate (LDR) channel) for control and signaling. The logical channel may function as a common mode channel for multi-mode operations. A piconet controller (PNC) within a piconet can utilize the LDR for beaconing, association, and for assigning Channel Time Allocations (CTAs). Inside a CTA period, multiple devices in the piconet can communicate using a single-carrier mode, an OFDM mode, or some other mode.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 092,613, filed August 28, 2008, assigned to the present assignee and expressly incorporated herein by reference. technical field [0003] Certain aspects of the disclosure relate generally to wireless communications, and more particularly to methods of partitioning wideband channels into common-mode channels to support multi-mode operation. Background technique [0004] An ultra-wideband (UWB) physical layer (PHY) may be used for millimeter wave communications (eg, communications using a carrier frequency of about 60 GHz). A common mode is available for dual-mode UWB PHYs that support single-carrier and Orthogonal Frequency Division Multiplexing (OFDM) modulation. A common mode is the single carrier mode used by both single carrier devices and OFDM devices for beaconing, network control signaling and basic rate data communications. To achieve in...
