摘要： A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access network in the communication system, and passing the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on these filtered values of the RABs. From the filtered RAB values a continuous fluid power level is determined each rate update. The access terminal maps the continuous fluid power level to actual physical transmissions by dithering among discrete power levels allowed by the physical layer.

摘要： A data-optimized communication system provides support for legacy access terminals, such as access terminals operating under the 1xEV-DO standard. The system also supports multiple-input multiple-output (MIMO) communications with access terminals configured to support MIMO. A number of MIMO spatial signatures are predefined or negotiated. MIMO rank and an identifier of the spatial signature determined at the MIMO access terminal are sent on the I-Branch and Q-Branch of the existing 1xEV-DO structure. In one embodiment, 1-bit rank and 3-bit spatial signature are transmitted through the I-Branch as a 4-bit symbol, replacing the data rate control (DRC) channel. In another embodiment, a 4-bit spatial signature is transmitted through the I-Branch, also replacing the DRC channel. A 2-bit rank is transmitted together with a 4-bit DRC channel through the Q-Branch. The 2-bit rank and the DRC channel can be distinguished because they are sent using different orthogonal codeword Walsh covers.

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 method and an apparatus of dynamically setting a rise-over-thermal (ROT) threshold to control user-to-user interferences in a wireless communication system are disclosed. The ROT threshold is set by determining whether an outage of communication has occurred, increasing the ROT threshold by a predetermined increment if the outage has not occurred, and decreasing the ROT threshold by a predetermined decrement if the outage has occurred.

摘要： Certain aspects of the present disclosure relate to techniques for managing resources for cooperative uplink transmission. A base station may determine different groups for a plurality of user equipments (UEs) participating in cooperative uplink transmission, and transmit mode configurations indicating whether or not UEs in each group are configured to transmit data as a data source or to relay data received from another UE configured to transmit data as a data source. A UE may participate, with one or more other UEs, in cooperative uplink transmission to the base station, wherein each UE belongs to a group. The UE may determine, for a transmission time interval (TTI), at least one operation to perform for the cooperative uplink transmission based, at least in part, on a group number of a group to which the UE belongs and an index of the TTI.

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： Techniques for efficiently sending and receiving data in a wireless communication system are described herein. The techniques utilize a slot structure that is backward compatible with existing design. The techniques include sending and receiving forward link packets that occupy less than a full slot of the slot structure. An output waveform, which includes at least one slot, is generated at an access point. Each slot is segmented into two half-slots, wherein at least one half-slot includes a data unit of a packet. At a terminal, the output waveform is received and processed to extract the data unit and the data unit is processed to determine whether it is accurate. The terminal also generates ACK/NACK information in response to the results of processing the data unit and transmits channel information including the ACK/NACK information. The access point interprets the ACK/NACK information to determine if the data unit should be resent.
