Abstract: An interference signal code power (ISCP) measurement is estimated in a time division multiple access/code division multiple access communication system. Signals transmitted in a particular time slot are received. A power level of the transmitted received signals of the particular time slot is measured. An association of ISCP values with measured power levels is provided. The measured power level is used to estimate an ISCP value. The estimated ISCP value is associated with that measured power level.

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: 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.

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: The present invention discloses a method and system for enabling efficient reduction of TFCs in the TFCS to achieve desired transmission, while remaining within desired power and data requirements. Upon the UE transmission power requirement exceeding the maximum or allowable transmission power the MAC shall be informed for subsequent TFC selection of all TFCs that currently exceed this limit. The UE will then chose the TFC with the next lower transmission power requirement and the sequence will continue until an acceptable TFC is determined. The present invention also enables the replacement of the TFCs in the FTCS and advanced determination of non-supported TFCs. The TFCs that require transmission power greater then the maximum or allowed UE transmission power shall be determined continuously in every TTI, not just in TTIs where the maximum power has been exceeded.

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 (1102), 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.
