摘要： A method and apparatus for estimating a signal-to-interference ratio (SIR) are disclosed. A received signal includes signal energy on multiple basis functions. Desired signal energy in the received signal is transformed onto a first basis function with constant polarity. The desired signal energy is estimated by coherently averaging signal energy on the first basis function. A noise power is estimated by averaging signal energy on each basis function other than the first basis function and accumulating the averaged signal energy from the basis function other than the first basis function and scaling the accumulated signal energy to account for a noise estimate from the first basis function. An SIR is estimated by dividing the desired signal energy by the noise power.

摘要： A grant that includes a resource allocation for a subframe set may be communicated. The subframe set may include a subframe resource and another subframe resource following the subframe resource. Sensing, during a sensing time prior to utilization of the subframe resource, that the unlicensed spectrum is available may be performed. Transmitting, based on the sensing, data on the subframe resource and the another subframe resource without further sensing may also be performed.

摘要： Described herein are methods to enable wireless cellular operation in unlicensed and lightly licensed, (collectively referred to as license exempt spectrum. Cognitive methods are used to enable use of unlicensed bands and/or secondary use of lightly licensed bands. Wireless devices may use licensed exempt spectrum as new bands in addition to the existing bands to transmit to a wireless transmit/receive unit (WTRU) in the downlink direction, or to a base station in the uplink direction. The wireless devices may access license exempt spectrum for bandwidth aggregation or relaying using a carrier aggregation framework. In particular, a primary component carrier operating in a licensed spectrum is used for control and connection establishment and a second component carrier operating in a licensed exempt spectrum is used for bandwidth extension.

摘要： Disclosed herein is HARQ management, scheduling, and measurements, among other things, for cooperative communication. For example, methods herein may be used in situations wherein relaying or helping mechanisms may comprise the use of a relay node which is part of a fixed infrastructure or a relay node which may be a mobile wireless transmit/receive unit (WTRU). In said situations, a first transmission with first data is established between an evolved NodeB (eNB) and a WTRU. A second transmission with second data is established between a relay node (RN) and the WTRU. Said first and second data are combined for decoding. A single HARQ feedback for said first and second transmissions is sent from the WTRU to the eNB.
