Abstract: Se proveen un método, componentes y un sistema para implementar control de potencia para transmisiones de comunicación inalámbrica que provee, iter alia, una solución para el desajuste de potencia de transmisión inicial para datos NRT estimando un error de polarización basado y ajustando la potencia ed transmisión a través de una cantidad de compensación para una estimación promedio de error de polarización sobre todas las transmisiones de grupos de datos, como ser asignaciones Temp-DCH secuénciales en un sistema UNTS. Un procedimiento alternativo para un sistema UNTS estima el error de polarización en un RNC en base a una medición promedio de potencia de código de transmisión por una estación base y aplica una compensación de error de polarización a la potencia de transmisión DL inicial en el RNC.

Abstract: A method, system, and components for outer loop power control (500) particularly useful for non-real time data services uses data transmitted in many short bursts of short duration, called Temp-DCH allocations (509). A target metric, preferably target SIR (502), is adjusted with differing step up and step down target metric adjustments. The initial target SIR (502) and th e transient step size for target SIR adjustment (505-507) is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation (50 9) of non-real time data.

Abstract: Enhancements are provided for the radio link control (RLC) protocol in wireless communication systems where variable RLC packet data unit (PDU) size is allowed. When flexible RLC PDU sizes are configured by upper layers, radio network controller (RNC)/Node B flow control, RLC flow control, status reporting and polling mechanisms are configured to use byte count based metrics in order to prevent possible buffer underflows in the Node B and buffer overflows in the RNC. The enhancements proposed herein for the RLC apply to both uplink and downlink communications.

Abstract: A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC 5 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 10 unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

Abstract: A method and apparatus for protecting high throughput (HT) stations (STAs) are disclosed. In one embodiment, a physical layer (PHY) legacy preamble transmitted by one STA is decoded by another STA that does not sue a legacy preamble. In another embodiment, one STA is identified by another STA by using bits in the preamble of a packet to indicate which PHY type will by used in the remaining portion of the packet. In yet another embodiment, one STA sends ready-to-send (RTS)/clear-to-send (CTS) or CTS-to-self messages for reserving a medium in the presence of another STA of a different type than the one STA. In yet another embodiment, an access point (AP) transmits a beacon or an association message including a capability information element (IE) that indicates operation or support for a legacy preamble, HT STA preambles and a medium access control (MAC) packet transmission with HT protection mechanisms. ACCESS POINT HIGH THROUGHPUT 4001 (STA) HIGH THROUGHPUT (H) 40N STATION (STA)

Abstract: An access point (AP) is disclosed comprising a wireless receiver configured to wirelessly receive capability and configuration data from a plurality of wireless transmit receive units, WTRUs, the capability and configuration data including information regarding coexistence of a 20 Mhz channel and a 40 Mhz channel. The AP further comprises a memory unit configured to store the capability and configuration data, and a wireless transmitter configured to wirelessly transmit, to at least one of the plurality of WTRUs, WTRU-specific configuration data comprising channelization data and legacy protection data based on the stored capability and configuration data.
