Abstract: Mobile station applications (419) may include an SI unit (409) for piggy backing SI onto data stored in data buffer (421) and also for adding an indicator to the SI information. The scheduling information and/or incremental control information (501) is piggy backed onto a data PDU and also has a sequence number (503) and an indicator field (505) which is added by the SI unit, such as SI unit (409), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary “1” value may be utilized to indicate that a previous SN of SI information remains valid. For example, “0100” of the bit map sequence may indicate that SN #3 is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.

Abstract: Una unidad base y un dispositivo identifican los espacios de búsqueda candidatos del canal de control. De acuerdo con un aspecto, la unidad base mapea la unidad remota a un conjunto de elementos de canal de control candidatos que constituyen un espacio de búsqueda candidato de canal de control para un canal de control para la unidad remota. La unidad base selecciona un canal de control que comprende uno o más elementos de canal de control a partir del conjunto de elementos de canal de control candidatos. La información de control para la unidad remota se comunica utilizando el canal de control seleccionado. De acuerdo con otro aspecto, la unidad remota utiliza una señal recibida de la unidad basepara identificar un espacio de búsqueda candidato de canal de control en el cual busca la señal de control.

A repetition value calculator (108) receives measurement occasion information (118) from the common channel selector (106) to calculate a repetition factor (120). A system frame number comparator (110) determines if a channel measurement occasion (128) should be performed based on the repetition factor (120), a common identifier (124) and a largest common channel transmission time interval (122). The method and apparatus further includes a measurement occasion generator (112) coupled to the system frame number comparator (110), wherein if a measurement occasion is to be performed, a measurement occasion command signal (126) is provided to the measurement occasion generator (112) and the measurement occasion generator generates the channel measurement occasion (128).

Abstract: A method for rate selection by a communication device for enhanced uplink during soft handoff in a wireless communication system includes a first step of receiving information from a scheduler. This information can include one or more of scheduling, a rate limit, a power margin limit, and a persistence. A next step includes determining a data rate for an enhanced uplink during soft handoff using the information. A next step includes transmitting to a serving base station on an enhanced uplink channel at the data rate determined from the determining step.

Abstract: The present invention provides a method of scheduling asynchronous transmissions for a plurality of subscriber units (12). The method includes receiving (305) information associated with a plurality of subscriber units that have uplink data to transmit, the information including uplink timing offset information associated with each of the subscriber units (12). Two or more subscriber units (12) are then selected (310) from a set of subscriber units having a timing offset differential, that is below a predetermined threshold, where the timing offset differential is the difference between the timing offset of a first subscriber unit and the timing offset of a second subscriber unit further selectively offset by a multiple of the transmission segment size, which minimizes the difference. The transmission segments, which are available for the uplink of data, are then allocated (315) between the selected two or more subscriber units (12), which limits the number of transmission segments that have at least one of an overlap or a gap, and the amount of any overlap or gap, in order to minimize wasted scheduling opportunities.

Abstract: A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.
