Abstract: Carrier aggregation allows concurrent transmission on multiple component carriers (CC) to increase the data rate. A user equipment (UE) device in a cellular network provides periodic or aperiodic channel state information of the DL channel to a base station (eNB) for each of the aggregated CCs. The UE receives two or more reference signals corresponding to two or more aggregated CCs from an eNB. The UE computes a plurality of channel state information (CSI) reports for each of two or more aggregated CCs derived from the two or more reference signals. The UE receives a positive CSI request from the eNB for a CSI report and transmits CSI feedback to the eNB comprising one or more CSI reports selected from the plurality of CSI reports.

Abstract: Systems and methods providing for dynamic switching between the various waveforms on the downlink are described. Embodiments of a dynamic downlink waveform switching implementation may, for example, support utilization of one or more multiple carrier (MC) waveform (e.g., OFDMA) or other high peak to average power ratio (PAPR) waveform and one or more SC (SC) waveform (e.g., discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM)) or other low PAPR waveform. Dynamic selection of a downlink waveform may be made by an access point based upon various metrics, including relative distance to a served an access terminal and the preference of downlink waveform indicated by a served an access terminal. A downlink waveform selection indication may be signaled from the access point to the served an access terminal using downlink control information (DCI).

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: Provided is an integrated circuit that calculates a power headroom (PHR) and that can preclude the recognition mismatch in which the reference formats of different UL grants are recognized between a wireless communication terminal apparatus and a wireless communication base station apparatus. For the PHR calculation of a PUSCH in a CC in which no UL grant is present, a UL grant, which was used for calculating the PHR in another CC having the same subframe number as the PUSCH, is used. For example, as to a subframe number=#1, the UL grant of CC #0 is used for calculating the PHR of CC #2 in which no UL grant is present.

Abstract: A wireless access point transmits a protocol data unit (PDU) that includes data and signaling for a plurality of user devices. The PDU spans a channel in frequency and an interval in time, and includes a first signaling section, a second signaling section and a traffic action. For each of a plurality of subchannels of the channel: the first signaling section includes (within the subchannel) a corresponding redundant copy of common signaling information for the user devices associated with the access point; the second signaling section includes (within the subchannel) a corresponding set of user-specific signaling information for a corresponding group of one or more of the user devices; and the traffic section includes (within the subchannel) a corresponding set of traffic data for the corresponding group of one or more user devices. Subchannels sizes may be configurable. A signaling set CRC may be included per subchannel.

Abstract: A terminal and a communication method thereof whereby, even in a case of employing an asymmetric carrier aggregation system and further employing a MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal, a transport signal forming unit forms transport signals by arranging, based on an arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.
