Problems solved by technology

[0007] One problem encountered when implementing mobile receivers that move between FLO networks with different SPs is that existing means cannot be used to communicate the correct values ​​of the different SPs to the receiver within the FLO waveform itself, since symbol demodulation requires the receiver to convert The correct values ​​for these parameters have been picked up

Embodiment Construction

[0016] Embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0017] FLO data is usually organized into superframes prior to transmission. Each superframe has a duration of one second. A superframe typically consists of 1,200 symbols (or a variable number of OFDM symbols based on the bandwidth being used) OFDM modulated with 4,096 subcarriers. Of the 1,200 OFDM symbols in a superframe, there are: two time-division multiplexed (TDM) pilot symbols (TDM1, TDM2); one wide-area identi...

Abstract

A new channel is added to FLO networks that carries embedded signaling parameter information. The design is such that regardless of the actual values of the signaling parameters conveyed, a receiver will be able to demodulate this new channel. Moreover, the addition of the new channel does not render a FLO network that has been so configured to not be backwards-compatible with existing devices.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application asserts the 60th / 60th / Priority of Provisional Application No. 951,952, which is assigned to the present assignee and is hereby expressly incorporated by reference herein. technical field [0003] The present invention relates generally to wireless communications, and more particularly to methods and apparatus for sensing signal parameters in wireless communications networks. Background technique [0004] Wireless communication networks, such as forward link only (FLO) networks, have been designed to provide real-time audio and video multicast to mobile devices. The FLO system is designed to work in a mobile environment where the channel characteristics in terms of the number of channel taps with significant energy, path gain and path delay are expected to change quite significantly over a period of time. To achieve good receiver performance and high spectral efficiency, FLO networks use Orthog...
