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： Apparatus and methods are provided for enabling communication on an enhanced access channel (EACH) without necessitating the additional features or channels usually implemented along with this capability. To this end, control information corresponding to the EACH transmission may be provided to an access terminal on a paging channel (PCH). For example, a base station may broadcast a general access parameters message (GAPM) to enable the access terminal to configure EACH transmissions. Further, the PCH may carry acknowledgment messages to inform the access terminal of the status of the EACH transmissions. Other aspects, embodiments, and features are also claimed and described.

摘要： Apparatus and methods are disclosed for positioning an access terminal in a CDMA wireless communication network utilizing a highly detectable pilot (HDP) scheme. Here, transmissions by base stations are divided in the time dimension into a plurality of time slots, or pilot control groups (PCGs). A subset of these time slots, according to a duty cycle, are exclusively allocated to the transmission of the HDP signals, while conventional data, control, and pilot transmissions are forgone during these HDP time slots. Among the HDP time slots, in accordance with a re-use pattern, groups of the cells take turns transmitting the HDPs at full base station power. In this way, access terminals are better capable of receiving a greater set of pilot signals for utilization in trilateration of the access terminals. Other aspects, embodiments, and features are also claimed and described.

摘要： Access terminals and network nodes are adapted to conduct access terminal registrations. In one example, an access terminal may obtain a data message for transmission, and registration information associated with the access terminal. The access terminal may send a message including the data message and the registration information. A network node can receive a message from an access terminal, where the received message includes a data message and access terminal registration information. The network node can register the access terminal with a network based on the access terminal registration information included in the received message. The network node can also process the data message included in the received message. Other aspects, embodiments, and features are also claimed and described.

摘要： A method for processing forward link channel signals generated by a CDMA base station includes time sharing by several mobile stations of spreading codes, which are orthogonal codes such as Walsh Code, and code-combining soft/softer handoff across sectors in the mobile station active set to increase dimensions on the CDMA2000 and WCDMA downlink while minimizing intra-sector interference. Since different parts of a packet or frame are transmitted to the user by the different base stations in the active set, earlier decoding and therefore early packet termination is enabled.

摘要： Access terminals and network nodes are adapted to conduct access terminal registrations. In one example, an access terminal with a respective class designation may receive a message including a plurality of periodic registration schedules, where at least one registration schedule is associated with an access terminal class. The access terminal may determine a periodic registration schedule associated with its respective class designation, and may perform periodic access terminal registrations according to the determined periodic registration schedule. In one example, a network node can obtain a plurality of periodic registration schedules, with at least one registration schedule associated with an access terminal class. The network node can transmit a message including the plurality of periodic registration schedules, and can conduct access terminal registrations according to the plurality of periodic registrations schedules. Other aspects, embodiments, and features are also claimed and described.

摘要： Aspects relate to frequency estimation and tracking. Frequency information is extracted based on an observation of a single symbol carrying pilot tones, which can be at any bandwidth location. Specifically, the frequency error information is extracted after selecting tones assigned to a specific user. The frequency error can be corrected based on the estimation. Further, the disclosed aspects can be applied to multi-path environments.
