Method, signal and apparatus for managing the transmission and receipt of broadcast channel information
First Claim
1. A method for transmitting broadcast channel information as part of a broadcast channel signal in a wireless communication system, the broadcast channel signal having one or more transmission intervals, each transmission interval including a plurality of transmissions, where one or more of the transmissions are active frames in which the broadcast channel information to be transmitted as part of each broadcast channel signal includes an invariant portion that remains static for each of the active frames within a particular transmission interval, and a variant portion that predictably changes with each successive active frame, the method comprising:
- subdividing the variant portion into an invariant subportion and a variant subportion, where the variant subportion includes at least one bit which changes value within the particular transmission interval;
identifying the invariant portion and invariant subportion from the broadcast channel information for each active frame, thereby forming invariant broadcast channel information for each active frame within a transmission interval that does not vary;
encoding the invariant broadcast channel information for each active frame within a transmission interval with a transmission specific configuration, wherein each active frame is encoded with a distinct transmission specific configuration based upon the position of the active frame relative to the beginning boundary of the transmission interval; and
transmitting the encoded invariant broadcast channel information for each active frame of each transmission interval in sequence thereby forming the broadcast channel signal.

Abstract
The present invention provides a method for transmitting broadcast channel information as part of a broadcast channel signal having one or more transmission intervals, where each transmission interval includes a plurality of transmissions, and one or more of the transmissions are active frames in which broadcast channel information is transmitted. Invariant portions that are present in the broadcast channel information are identified separate from any variant portions and are encoded for transmission, and the variant portions are used to select transmission specific configurations, which can be detected during the decoding by the receiver. Upon detection of the transmission specific configuration used to encode the invariant portions, the value of the variant portion can be identified and reintroduced as part of the received broadcast channel information.

13. A wireless communication device comprising:
-
an encoder configured to convert data to be transmitted to a broadcast channel signal, said broadcast channel signal including; one or more transmission intervals, each transmission interval including multiple transmissions where one or more of the transmissions are active frames in which broadcast channel information to be transmitted as part of each broadcast channel signal includes an invariant portion that remains static for each of the active frames within a particular transmission interval, and a variant portion that predictably changes with each successive active frame; wherein the variant portion includes an invariant subportion and a variant subportion, where the variant subportion includes at least one bit which changes value within the particular transmission interval, said invariant subportion being identified with the invariant portion for thereby forming invariant broadcast channel information for each active frame within a transmission interval that does not vary, where the variant subportion is used to determine a transmission specific configuration to be respectively applied to the invariant broadcast channel information of a particular active frame, based upon the value of the variant subportion, which coincides with the position of the active frame relative the beginning boundary of the transmission interval; and a transmitter for communicating the broadcast channel signal in the form of a wireless communication signal. - View Dependent Claims (14, 15, 16)

17. A wireless communication device comprising:
-
a receiver for receiving a wireless communication signal in the form of one or more transmission intervals, where each transmission interval includes a plurality of transmissions, where one or more of the transmissions are active frames; and a decoder for converting the received signal into an invariant portion of data intended to be transmitted prior to an encoding for transmission, said decoder including a controller, wherein the controller is configured to attempt to decode each active frame as it is received, using one of a plurality of decoding sequences, respectively corresponding to a transmission specific configuration associated with the transmission position relative to a beginning boundary of the transmission interval; and wherein a determined one of the plurality of decoding sequences, which allows for the successful decoding of the received wireless signal associated with a particular active frame is used to reintroduce a variant portion to the invariant portion of the data intended to be transmitted. - View Dependent Claims (18, 19, 20)
