Abstract: The disclosed embodiments provide for methods and systems for selecting sectors for handoff in a communication system. According to one aspect, the method includes monitoring an indicia of transmit power on a plurality of RL control channels directed to a plurality of sectors, and selecting one of the sectors as a candidate for a RL handoff. The disclosed embodiments also provide for methods and systems for indicating a selected serving sector for handoff in a communication system. According to one aspect, the method includes sending a first signal to a first sector to indicate the first sector as a serving sector for a forward-link handoff, and sending a second signal to a second sector to indicate the second sector as a serving sector for a reverse-link handoff.

Abstract: De acuerdo con uno de los aspectos del presente se provee un método en el cual un grupo de usuarios en un sistema que utiliza un mecanismo de retransmisión tal como el ARQ (Automatic Repeat Request, Requerimiento Automático de Repetición), es dividido en forma de múlitiples sub-conjuntos de usuarios. A cada uno de los usuarios le es asignada una cantidad de canales para la retransmisión de información. La cantidad de canales asignada a cada uno de los usuarios es determinada, por lo menos en parte, a la cantidad de sub-grupos y en base a una cantidades de canales disponibles en el sistema. Los intervalos de transmisión son alternados entre los múltiples sub-grupos, de manera tal que se permite que solamente uno de los sub- grupos de usuarios pueda transmitir información durante cualquier intervalo de transmisión. Un intervalo ocioso durante el cual un usuario particular en el primer grupo no transmite información, es utilizado como período de espera para el acuse de recibo de una transmisión anterior por el usuario particular.

Abstract: According to one aspect of the invention, a method is provided in which a group of users in a system that employs a retransmission mechanism such as Automatic Repeat Request (ARQ) is divided into multiple sub-groups of users. Each user is assigned a number of channels for transmission of information. The number of channels assigned to each user is determined based, at least in part, on the number of the sub-groups and a number of channels available in the system. Transmission intervals are alternated among the multiple sub-groups such that only one of the sub-groups of users is allowed to transmit information during any transmission interval. An idle interval during which a particular user in the first group does not transmit information is used as a waiting period for acknowledgement of a previous transmission by the particular user.

Abstract: Techniques for efficient W-CDMA modulation are disclosed. In one aspect, a multiplexing/coding chain for use in modulation such as that defined by the W-CDMA specification is disclosed. In another aspect, transport blocks are processed and concatenated, utilizing memory efficiently. This aspect has the further benefit of preparing transport channels for efficient subsequent processing. It also allows for ease of interface with the transport channel source. In another aspect, the use of repeated channel coding is used in lieu of an interleaver memory to provide channel coding and interleaving. These aspects, collectively, yield the advanced benefits of a system, such as W-CDMA, in a hardware efficient manner. The techniques described herein apply equally to both access points and access terminals. The techniques are not limited to W-CDMA systems; they are quite suitable to other systems requiring the various benefits the invention offers. Various other aspects of the invention are also presented.

Abstract: A system and method for power control and scheduling of sub-carriers in an OFDM communication system. The receiver dynamic range can be minimized by a power control loop that attempts to maintain received power over a noise floor in a predetermined range. If the received power relative to a noise floor in allocated sub-carriers exceeds the predetermined range and the total received power is at the minimum, the scheduling system allocates an additional sub-carrier to the communication link. Additionally, ifthe received power relative to the noise floor is less than the predetermined range minimum, and the total received power is at a maximum, the scheduling system de-allocates a sub-carrier from the communication link. The scheduling system may also adjust an encoding rate to maintain a relatively constant symbol rate in each sub-carrier.

Abstract: Noise and interference can be independently measured in a multiple user Orthogonal Frequency Division Multiplexing (OFDM) system. Co-channel interference is measured in a frequency hopping, multiple user, OFDM system by tracking the sub-carriers assigned to all users in a particular service area or cell. The composite noise plus interference can be determined by measurin g the amount of received power in a sub-carrier whenever it is not assigned to any user in the cell. A value is stored for each sub-carrier in the system a nd the value of noise plus interference can be a weighted average of the presen t value with previously stored values. The noise component can be independentl y determined in a synchronous system. In the synchronous system, all users in a system may periodically be prohibited from broadcasting over a sub-carrier a nd the received power in the sub-carrier measured during the period having no broadcasts.

Abstract: A method and apparatus for ZoneCode-based registration is described. A list of RegistrationZoneCodes is stored (502), wherein the list of RegistrationZoneCodes is associated with subnets visited by the access terminal. It is determined if a protocol cache information (504) is keyed by a (Subnet, RegistrationZoneCode) pair. The cached information is deleted (506) when the (Subnet, RegistrationZoneCode) pair is deleted from a RegistrationZoneCodeList. NoMPMinzoneSignatureustsize entries are stored (508) in the RegistrationZoneCodeList. It is determined if the (Subnet, RegistrationZoneCode) pair from a SectorParameters message from a sector in an Active Set is not included (510) in the RegistrationZoneCodeList. The (Subnet, RegistrationZoneCode) pair entry from a SectorParameters message from a sector in an Active Set are added to the RegistrationZoneCodeList (512). An ActiveSetManagement.SentPilotReport command is generated (514). It is determined if there are more entries in the RegistrationZoneCodeList than the supported size (516) of the RegistrationZoneCodeList. The oldest (Subnet, RegistrationZoneCode) pair entries are deleted in the RegistrationZoneCodeList (518).
