    摘要: Embodiments disclosed herein relate to providing effective interference control in a wireless communication system. In one embodiment, a method for determining an interference level in a wireless communication system is described, including: determining a rise-over-thermal (RoT) metric based on an RoT received at each receiver antenna of an access network, the RoT relating to a ratio of a total energy to a thermal energy received at each receiver antenna; determining an interference-reduction factor (ρ) in relation to an interference energy reduced from the total energy received at each receiver antenna; and determining an effective rise-over-thermal (RoTeff) based on the RoT metric and the interference-reduction factor, the RoTeff relating to the interference level in the wireless communication system. The method may further include comparing the RoTeff with a threshold and relating the result of the comparison (e.g., the sector loading status) to each access terminal in communication with the access network.

    摘要: A method and an apparatus for scaling demodulated data symbols contained in a packet to generate scaled log-likelihood ratios for Turbo decoding are disclosed. A packet consists of one or more subpackets depending on the type of packet. Each subpacket is identified by a subpacket identification number. The payload size of the packet and the subpacket identification number may be determined by decoding a reverse rate indicator (RRI) channel. A scale factor which is associated with a specific subpacket identification number and a specific payload size results in a performance measure that is closest to an expected performance measure. The scale factor is used for scaling the demodulated data symbols to generate scaled log-likelihood ratios for Turbo decoding.

    摘要: A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The AN may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.

    摘要: A receiver may train its equalizer using consecutive pilot bursts, divide the traffic between the consecutive pilot bursts into multiple sub-segments, and interpolate the trained equalizer coefficients to obtain the coefficients for equalizing one or more of the sub-segments. The receiver may also determine signal to interference and noise ratio (SINR) values based on each of the consecutive pilot bursts, and interpolate the SINR for decoding one or more of the sub-segments. The receiver may be an access terminal receiver operating in a code division multiple access (CDMA) cellular system.
