摘要： A receiver (200) is provided receiving signals from differing base stations (BTSA and BTSB). The signal from BTSA is encoded using a first rate convolutional encoder while the signal transmitted from BTSB is encoded using a second rate convolutional encoder. Since the multiple base station links may result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, in the preferred embodiment of the present invention, the resulting symbols are passed to multiple branch metric circuits (210–211), where branch metrics (μi) for the symbols are obtained. After the ith branch metrics for the base stations are computed, the branch metrics for each base station are passed to a combiner (212) where they are combined.

摘要： Methods and systems are provided for transmission power control in a multiple access communication system, providing power ramping of a noise floor power level in advance of a high data rate transmission, at a comparatively higher power level, by a mobile station. The preferred method includes receiving a request at a base transceiver station (BTS) for a data transmission by a first mobile station of a plurality of mobile stations (300), the data transmission to have a predetermined data transmission power level; measuring a noise floor power level (305); and comparing the measured noise floor power level to the predetermined data transmission power level (310). When the measured noise floor power level is less than the predetermined data transmission power level, the BTS schedules the data transmission from the first mobile station to occur following the power ramping of the noise floor, and directs the plurality of mobile stations to incrementally increase their transmit power levels to ramp the noise floor power level. Other methodologies to ramp the noise floor power level include injecting analog or simulated noise into the receive path of BTS, or directing the mobile station to transmit meaningless data at increasing power levels prior to transmission of requested data.

摘要： A transmitting device (100) transmits a first packet, comprising a second encryption vector, that is encrypted using a first encryption vector. The transmitting device transmits a second packet that is encrypted using the second encryption vector if an acknowledgement message is received within a predetermined time after transmitting the first packet; otherwise, the first packet is re-transmitted. Upon receipt of the first packet, a receiving device (102) decrypts the first packet using the first encryption vector and transmits the acknowledgement message. Upon receipt of the second packet; the receiving device attempts to decrypt a portion of the second packet using the first and second encryption vectors. If the portion of the second packet was successfully decrypted using the first encryption vector, the receiving device re-transmits the acknowledgement message for the first packet; otherwise, it transmits an acknowledgement message for the second packet.

摘要： A communication system (100) that includes base stations (103-109) comprising selection circuitry (207) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit (113), frames received by non-call anchoring base stations (105, 107) are backhauled to a switch (101). The switch (101) then sidehauls the frames to the call anchoring base station (103), where selection and call processing functions for the particular call takes place.
