Abstract: A method, apparatus and system for wireless communication are described. The method includes transmitting and receiving data to and from one or more wireless transmit/receive units (WTRUs) via an underlay system access link. The underlay system is non-standalone, and control information is provided from an overlay system. An underlay base station is linked to other underlay base stations to implement a mesh backhaul. The method also includes transmitting and receiving at least a portion of the data to or from an overlay base station via backhaul links and receiving control data from the overlay base station. The data is split at a packet data convergence protocol (PDCP) entity, and the PDCP entity terminates in the overlay base station and a radio link control (RLC) entity terminates in the underlay base station.

Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

Abstract: Data traffic may be mapped such that it may be routed via a component carrier. The data traffic may be mapped based on QoS, traffic offload, or the like. This may provide the ability to map certain data to specific component carriers. For example, this may provide a user subscription model with the ability to map one or more services to license exempt (LE) carriers, but not to other carriers. As another example, a user downloading a high definition movie may not want this to be counted towards his or her monthly quota on a licensed carriers or may want to pay flat rate to access supplementary carriers for such services. Allowing data to be mapped such that it may be routed via a component carrier via a component carrier may allow the user to map the data for the high definition movie to a LE carrier.

Abstract: Methods and apparatus for changing cell range coverage are disclosed. The coverage may be changed on a per-sub-frame basis. An antenna beam elevation tilting angle may be adjusted to provide different effective downlink (DL) coverage. For example, a subframe may be a small tilt subframe or a large tilt subframe. A network or evolved NodeB (eNB) may determine data channel transmission power to adjust cell range per subframe. Low Power Subframe (LPS) may be used alone or with Almost Blank Subframe (ABS) to transmit data. Timing Advance (TA) handling for uplink (UL) transmissions is described. A common TA (CTA) may be determined for multi-site UL signaling. UL power control may be determined for UL transmission to multiple sites. Radio Link Monitoring (RLM) may be performed for multiple sites on a carrier frequency. A wireless transmit/receive unit (WTRU) may maintain synchronization in selected subframes for multiple cells.

Abstract: 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.

The light emitting device is configured to convert the data, the filler luminance value, and the dimming information to visible light for transmission to the second VLC device.

Abstract: 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.

In accordance with another embodiment, the Node-B may inform the HSDPA transmission schedule to a radio network controller (RNC) and the RNC coordinates the HSDPA transmission schedule and a compressed mode transmission gap schedule of the WTRU.

Abstract: The invention includes various embodiments for use in physical layer processing. One embodiment determines the address mapping of bits in the physical channel buffer from the address of bits in the first interleaver buffer. The physical channel buffer addresses are determined corresponding to addresses of the bits after rate matching, bit scrambling, second interleaving and physical channel mapping. The bits are directly read from the first interleaver buffer and written to the physical channel buffer using the determined physical channel buffer addresses. Another embodiment determines the address mapping of bits in the first interleaver buffer from the address of bits in the physical channel buffer. The first interleaver buffer addresses are determined corresponding to addresses of the bits after reverse rate matching, reverse bit scrambling, reverse second interleaving and reverse physical channel mapping.
