Title: Synchronization of forward link base station power levels during handoff between base station sectors in a mobile radio communication system
Inventor: BENDER PAUL E
IPC: H04W56/00
Filed: 1999-02-19
Abstract: A method and apparatus for controlling the transmit power levels of first and second base station transceivers, wherein the first and second base station transceivers are respectively associated with first and second sectors of a cell. The received signal strength of a communication signal arriving at the mobile station is initially determined. A  power control value that is based on the received signal strength is then transmitted from the mobile station to the first and second base station transceivers. A first received power control value is next generated by attempting to receive the transmitted power control value at the first base station transceiver, and a second received power control value is generated by attempting to receive the transmitted power control value at the second base station transceiver. A  common transmit power value is calculated at a base station controller for the first and second base station tranceivers when the first and second received power control values are unequal.  The communication signal is then transmitted from the first and second base station transceivers in accordance with the common transmit power value.

Patent CA-2291965-A1 (CA)
Inventor: SEN SANJOY KUMAR
IPC: H04L1/18
Filed: 1999-12-10
Abstract: An improved method and system for limiting data packet transmission within a digital mobile telephone communication network, such as a code division multiple access (CDMA) mobile telephone communication network, by discarding unsuccessfully transmitted radio link protocol frames is disclosed. A code division multiple access (CDMA) mobile telephone communication network includes a mobile telephone, a base station, a mobile switching center, and a network Interworking Function. Within the CDMA mobile telephone communication network, each point-to-point protocol data packet is typically divided into multiple radio link protocol frames before their transmissions over an air link. In accordance with a method and system of the present invention, a marker bit is provided for each of the radio link protocol frames. The marker bit can be part of the frame header and will be removed before air link transmission. The marker bit of a first one of the radio link protocol frames is set to a first logical state (such as a logical "1") and the rest of the radio link protocol frames are set to a second logical state (such as a logical "0"). In response to an unsuccessful transmission of one of the radio link protocol frames, all of the radio link protocol frames within the same point-to-point protocol data packet having the marker bit set to the second logical state are discarded, after a predetermined number of unsuccessful re-transmission attempts.
