摘要:
A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

摘要:
A method and apparatus for adaptively biasing a channel quality indicator (CQI) used for setting a configuration of communication between a transmitter and a receiver in a wireless communication system. The receiver sends a CQI and positive acknowledgement (ACK)/negative acknowledgement (NACK) messages to the transmitter. The ACK/NACK messages indicate the absence or presence of error, respectively, in a transmitted data packet. The CQI is derived from the signal-to-interference ratio (SIR) and the ACK/NACK messages. The transmitter calculates the block error rate (BLER) of the transmitted data packets based upon the ACK/NACK messages sent from the receiver. The transmitter compares the BLER of the transmitted data packets to a target BLER and biases the CQI based on the comparison in order to achieve the target BLER.
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.
