Abstract: A METHOD SYSTEM AND COMPONENTS FOR OUTER LOOP POWER CONTROL PARTICULARLY USEFUL FOR NON-REAL TIME/ REAL TIME DATA SERVICES USES DATA TRANSMITTED IN MANY BURSTS OF SHORT DURATION, CALLED TEMP-DCH ALLOCATIONS. A TARGET METRIC, PREFERABLY, TARGET SIR, IS ADJUSTED WITH DIFFERING SET UP AND DOWN LEVELS TO CONVERGE ON A RELATIVELY LOW STEADY STATE LEVEL (310) OF STEP UP AND STEP DOWN TARGET METRIC ADJUSTMENTS. THE INITIAL TARGET SIR AND THE TRANSIENT STEP SIZE FOR TARGET SIR ADJUSTMENTS IS DETERMINED IN A DYNAMIC WAY IN THE OUTER LOOP POWER CONTROL FOR EACH TEMP-DCH ALLOCATION OF NON-REAL TIME DATA.

Abstract: A wireless local area network (WLAN) includes at least one high throughput-enabled access point (AP) and at least one high throughput-enabled station (STA). A STA and a target AP communicate high throughput-related information and the STA performs a basic service set (BSS) transition to the target AP based on the high throughput-related information. The high throughput-related information may be included in an IEEE 802.11r, 802.11k, or 802.11v signaling message. The STA may send measurement reports for an extended range and a normal range of an AP separately, or may send a combined measurement report for an extended range and a normal range of an AP. A network management entity may obtain current status information of the STA and the AP regarding high throughput capabilities, features and parameters and selectively enable and disable at least one of the high throughput capabilities, features and parameters of the STA and the AP.

Abstract: In a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B (NB), an activation or deactivation state is determined for each of a plurality of HARQ processes. A signal that includes the activation or deactivation state for each of the HARQ processes is transmitted to the WTRD. In response to receiving the signal, the WTRU activates or deactivates a particular HARQ process in accordance with the activation or deactivation state for each of the HARQ processes contained in the received signal.

Abstract: A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which also applies to a single mode as a trivial case. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

Abstract: A method, components and a system are provided for implementing power control for wireless communication transmissions that provides, inter alia, a remedy for the mismatch of initial transmission power for NRT data by estimating a bias error based and adjusting the transmission power by a compensation amount for an averaged bias error estimation over all data set transmissions, such as sequential Temp-DCH allocations in a UMTS system. An alternative approach for a UMTS system estimates the bias error at a RNC based on an averaged transmit code power measurement by a base station and applies a bias error compensation to the initial DL transmit power at the RNC.

Abstract: Se describen un método y una arquitectura del control de enlace de radio (RLC) en modo de acuse de recibo (AM), en un acceso a paquetes de alta velocidad (HSPA). El RLC se configura para operar en AM y procesar unidades de datos del protocolo (las PDU) de tamano flexible. Específicamente, un método y una arquitectura de RLC con AM en los que las SDU del RLC se segmentan y/o concatenan unicamente en el momento de enviar las PDU hacia las capas inferiores o inmediatamente antes. Esto incluye una interface con las capas inferiores con el fin de promover tamanos de PDU flexibles para el RLC con AM.

Abstract: A METHOD (200), COMPONENTS AND A SYSTEM ARE PROVIDED FOR IMPLEMENTING POWER CONTROL FOR WIRELESS COMMUNICATION TRANSMISSIONS THAT PROVIDES, INTER ALIA, A REMEDY FOR THE MISMATCH OF INITIAL TRANSMISSION POWER FOR NRT DATA BY ESTIMATING A BIAS ERROR BASED AND ADJUSTING THE TRANSMISSION POWER BY A COMPENSATION AMOUNT FOR AN AVERAGED BIAS ERROR ESTIMATION OVER ALL DATA SET TRANSMISSIONS, SUCH AS SEQUENTIAL TEMP-DCH ALLOCATIONS IN A UMTS SYSTEM. AN ALTERNATIVE APPROACH FOR A UMTS SYSTEM ESTIMATES THE BIAS ERROR AT A RNC BASED ON AN AVERAGED TRANSMIT CODE POWER MEASUREMENT BY A BASE STATION AND APPLIES A BIAS ERROR COMPENSATION TO THE INITIAL DL TRANSMIT POWER AT THE RNC.
