摘要： In a CDMA data communication system capable of variable rate transmission, utilization of beam switching techniques decreases the average interference caused by transmissions of a base station to subscriber stations within a cell, and in neighboring cells. Base stations utilize multiple transmit antennas, each transmitting signals at controlled amplitudes and phases, to form transmit signal corresponding to sector divisions. Data and reference signals are transmitted along sector division beams that alternate according to fixed time slots in order to increase system capacity and data rates by maximizing carrier-to-interference ratios (C/I) measured at subscriber stations.

摘要： A novel method and apparatus for providing both voice services and data services in a High Data Rate (HDR) wireless communication system. At least one sub-channel is formed on the forward link of the HDR system. The at least one sub-channel comprise at least one time slot that occupies a specified position in a frame of the forward link. The at least one sub-channel is assigned for voice services. The voice services at the at least one sub-channel are provided in accordance with a CDMA principles. Such principles are disclosed e.g., in IS-95, cdma2000, or other standards known to one skilled in the art. The remaining time slots are used for data services. In another aspect of the invention, additional sub-channels are formed, utilizing all remaining time slots. The additional sub-channels are assigned to data services, such that each sub-channel carries data to a different user. The number of sub-channels assigned to voice services, and the number of sub-channels assigned to voice services changes with varying needs for voice services and data services.

摘要： A method of supervising on the forward link in a high data rate system is disclosed, wherein a base station transmits to an access terminal on a forward traffic channel only when the base station has data to send to the access terminal. Each access terminal generates periodic data rate measurements based on the received forward link signal. Each access terminal then minimizes the period in which it transmits on the reverse link without being power-controlled by turning off its transmitted based on the data rate measurements.

摘要： The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and/or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values arc received. Each list of processed attribute values includes attribute values considered acceptable to the second entity. The layers and protocols in the first entity are then configured in accordance with the received list of processed attributes and their associated processed attribute values. Other features related to configurable layers and protocols are also provided.

摘要： In a system including a resource (100) which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.

摘要： When a resource of limited capacity is shared by several users, it is possible for the usage rates of the users to exceed the resource's capacity, thereby causing an overload condition. In a system or method according to an embodiment of the invention, at least some of the users have a set of persistence vectors. When an overload condition is detected, the usage rate of at least one of these users is changed, at least in part according to the user's set of persistence vectors.

摘要： A method for generating a message authentication code (MAC) includes the steps of distributing the bits of a message into a larger message in accordance with a pseudorandom number distribution format. The cyclic redundancy check (CRC) bits of the larger message are computed and used as the MAC for the message. The larger message need not be created. The remainder modulo the CRC polynomial of a polynomial xi, where i is the intended bit position in the 'larger message', is calculated. An exclusive-OR(XOR) operation is performed, bit by bit, on the CRC and the calculated remainder to derive the new CRC.

摘要： A method and system for transmitting digital data by extending the sequence numbering range for a selective repeat transmission protocol are described. In accordance with one embodiment of the invention, data frames (70) are transmitted including an eight-bit sequence number (72) and a one-bit retransmit flag (74). The one-bit retransmit flag (74) indicates whether the frame is newly transmitted or retransmitted due to a failed first transmission. Transmit (50) and receive (52) systems each maintain a twelve-bit sequence number referred to as a 'long sequence number' comprised of the eight-bit sequence number transmitted with each frame and a four-bit extension. The long sequence number is transmitted within a control frame (82) and the eight-bit sequence number is transmitted within the data frame (72).

摘要： Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.
