    摘要: Systems, methods, and instrumentalities are disclosed herein to determine a gain factor. A user equipment (UE) may determine that an S-E-DPCCH and an E-DPCCH are to be transmitted on a primary stream. The UE may calculate an E-DPCCH gain factor using a gain factor calculation and apply the -DPCCH gain factor. The UE may calculate an E-DPCCH gain factor reduction. For example, the E-DPCCH gain factor reduction may compensate for changes from single stream transmission to multiple stream transmission. The UE may apply the E-DPCCH gain factor reduction to the E-DPCCH gain factor. The UE may apply the E-DPCCH gain factor reduction to an S-E-DPCCH gain factor.

    摘要: Methods and systems for enabling MU-MIMO functions on a UE are disclosed. A precoder codebook with precoding matrices can be generated to assist in improving system throughput. Existing specifications designed for two bit precoding information can be used to communicate higher numbers of bits of precoding information by reinterpreting fields described by such specifications. Channel state information can be provided to a base station using several disclosed feedback mechanisms. A UE can determine a current MIMO transmission mode using various implicit and explicit dynamic signaling mechanisms or semi-dynamic signaling where MIMO mode data is received from a higher layer.

    摘要: A method and apparatus that applies medium access control (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 may also apply to a single mode. 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.

    摘要: A method and system for eliminating interference caused by hidden nodes is disclosed. An initiator control message is defined for an initiator, (typically a wireless station (STA)), in order to begin an aggregate frame exchange with at least one responder. The initiator control message includes information on the queue sizes at the initiator. A responder, (typically an access point (AP)), sets up the required protection for the transmission of data by the initiator based on information on the queue sizes indicated in a field of the initiator control message using a responder control message. Other STAs that receive the responder control message set parameters for a wireless medium access accordingly. In another embodiment, multiple receiver aggregate multi-poll (MMP) and power save aggregation descriptor (PSAD) control frames are configured for transmission by a non-AP STA to provide enhanced scheduling and mitigate hidden node problems.

    摘要: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.

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.
