Packet transmission method
View Patent ↗A wireless system includes base station transceivers ( 102-104 ) to communicate with at least one mobile station ( 108 ), the base station transceivers communicate with a network controller ( 110 ). The base station controls a header for a packet frame to be communicated between the base station transceiver and the network controller wherein a portion of the header identifies the frame as one containing no data package. The data bits of the header field may contain a predetermined bit pattern for a frame including no data package. Information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a decoding metric passes a threshold. The information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a CRC for the frame received from the mobile station fails.
1. For a wireless system including base station transceivers to communicate with at least one mobile station, the base station transceivers communication with a network controller, a method comprising the steps of:
determining whether to convey information received from a mobile station in a backhaul frame based on a decoding metric:
in response to determining to not convey the information in the frame, controlling, in a base station transceiver, a header for a packet frame to be communicated between the base station transceiver and the network controller wherein a portion of the header identifies the frame as one containing no data package; and
transmitting the frame to the network controller with the constructed header and without the data package.
2. The method according to claim 1 wherein data bits of a header field contain a predetermined bit pattern for a frame including no data package.
3. The method according to claim 1 wherein the information received by the base station from the mobile station is dropped, and the header information is replaced with the specified bit pattern, if a decoding metric passes a threshold.
4. The method according to claim 1 wherein the information received by the base station from the mobile station is dropped and the header information is replaced with the specified bit pattern if a CRC for the frame received from the mobile station fails.
5. The method according to claim 1 wherein the decoding metric comprises at least one of a finger lock status, a symbol error rate, a bit error rate, and signal-to-interference ratio, and a signal-to-noise ratio.
