Title:
COMMON-MODE PARTITIONING OF WIDEBAND CHANNELS
Document Type and Number:
WIPO Patent Application WO/2010/025244
Kind Code:
A3
Abstract:
Certain aspects of the present disclosure 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.
