Abstract: A method implemented in a transmitter/transceiver, the method including mapping any number of elements of an uplink control information (UCI) signal sequence (SS) to available subcarriers for transmitting an OFDM symbol for carrying information associated with a Physical Uplink Shared Channel (PUSCH), each of the subcarriers having at least two layers, precoding the mapped elements as a function of the layer of the subcarrier to which the elements are mapped, wherein a first precoding applied to a mapped element of a first layer of a subcarrier is different than a second precoding applied to a mapped element of a second layer of the same subcarrier, feeding the mapped elements of the UCI SS to an IDFT unit and transforming the mapped elements into an IDFT transformed signal that includes the mapped elements of the UCI SS carried by a plurality of resources for transmission.

Abstract: A base station may sense, on a cell using unlicensed spectrum, that the unlicensed spectrum is available for transmission. The base station may transmit, after sensing that the unlicensed spectrum is available, consecutive subframes. Each subframe may include a physical downlink control channel and a physical downlink shared channel.

Methods for UCI transmission in the uplink control channel, uplink shared channel or uplink data channel are disclosed. The methods include transmitting channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK), channel status reports (CQI/PMI/RI), source routing (SR) and sounding reference signals (SRS). In addition, methods for providing flexible configuration in signaling UCI, efficient resource utilization, and support for high volume UCI overhead in LTE-A are disclosed.

Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.

Abstract: Coexistence gaps may permit one radio access technology (RAT) to coexists with another RAT by providing period in which one RAT may be silent and another may transmit. Methods may account for the RAT traffic and for the presence of other secondary users in a channel. Methods may be provided to dynamically change the parameters of a coexistence gap pattern, such as the duty cycle, to adapt to both the RAT traffic and the presence of other secondary users. Methods may include PHY methods, such as synchronization signal (PSS/SSS) based, MIB based, and PDCCH based, MAC CE based methods, and RRC Methods. Measurements may be provided to detect the presence of secondary users, and may include reporting of interference measured during ON and OFF durations, and detection of secondary users based on interference and RSRP/RSRQ measurements.

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.
