    摘要: A mobile station and base station are capable of communicating in a wireless network via a set of contiguous or non-contiguous sub-bands. The base station transmits a resource allocation to the mobile station. The resource allocation message includes a sub-band index (SBI) field, a number of messages field, a contiguous allocation indicator field, or a combination of these. Based on the SBI field, one or more of the number of messages field and contiguous allocation indicator field, the mobile station can identify the set of sub-bands allocated to it by the base station.

    摘要: The present invention provides a method and an apparatus for adapting a data rate that a mobile station indicates to a base station for transmission on a forward link in a cellular system. The method comprises measuring a first value indicative of strength of at least one of a primary and a secondary pilot. The method further comprises compensating the first value indicative of strength of the pilot based on an offset to select a second value indicative of the data rate for the base station. The base station may determine an offset value for compensation and send an indication to the mobile station during the setup of the mobile station. When the mobile station connects to the base station, a measurement of a channel condition (i.e., pilot) may determine a revised data rate for transmission of a next data packet on the forward link.

    摘要: The present invention provides a method and an apparatus for a wireless communication between at least one mobile station and a base station in a cellular system. The method comprises providing a desired spreading in time and frequency domains to transmit data using at least two carriers in a transmission on an uplink to the base station. Either the base station may provide an indication to the mobile station to enable the desired spreading, or alternatively, the mobile station may request it. A spread-spectrum cellular system may enable a mobile station to provide a two-dimensional spreading, which distributes spreading in time and frequency directions. A single two-dimensional spreading code or at least two one-dimensional spreading codes may provide a two-dimensional spreading. In this way, in an uplink transmission using a multi-carrier, code division multiple access (MC-CDMA) protocol, by varying the data portions being spread in time and frequency domains a joint spreading may result. The joint spreading may distribute spreading codes in the time and frequency directions to distribute the spreading in a transmission. When using the MC-CDMA protocol, a mobile station may select one or more spreading formats in an uplink transmission that may increase the success rate of the packet transmission. Moreover, use of a particular spreading format in a flexible manner may reduce the packet delay and suppress intra-cell interference.

    摘要: A method enables the use of a secondary pilot signal and a secondary antenna(s) in the forward link of a CDMA-based cellular network employing a slotted transmission scheme with a time-multiplexed primary pilot signal, with backwards compatibility. The forward link is divided into a number of time slots. For communications with “legacy” mobile stations that expect transmissions from a single, primary antenna (and that expect a single, primary pilot signal), during some of the time slots, only the primary antenna is used for transmissions, including transmitting the primary pilot signal. Neither the secondary pilot channel nor any other signals from the secondary antenna are transmitted. During the remaining time slots: (i) the primary pilot signal is transmitted from the primary antenna, and the secondary pilot signal is transmitted from the secondary antenna, but at different times; and (ii) data meant for the legacy mobile stations is not transmitted.

    摘要: A method to adjust the burst transmission duration time, in a high speed digital wireless communication system, to provide sufficient time for the transmission of data when all the data is not available at the time of transmission. According to the method of the invention, after the burst transmission is begun, the burst is maintained active as additional data is selected within a known time period following the previous detected data packet and the detected data is appended to the active burst transmission. The invention further terminates the burst duration when no additional data is detected within the redefined time period following the previous detected data packet.
