摘要： Methods, systems, and devices are described for wireless communication. A device may use enhanced reporting mechanisms to support control information reporting on shared spectrum. In some cases, a device may utilize enhanced component carriers (eCCs) for data transmissions. In one example, the device may transmit control information (e.g., ACK/NACK, CSI, etc.) to a corresponding device using a CCA exempt transmission (CET). In another example, a device may report control information quasi-periodically. For instance, a device may be assigned a specified interval and a control feedback window for reporting control information (e.g., CSI). The window may provide a duration prior and subsequent to the specified interval during which a UE may transmit control information. For example, the device may perform a CCA reserving the channel for a duration that does not include the specified interval but may transmit feedback information based on determining the specified interval falls within the assigned window.

摘要： Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.

摘要： A base station may determine a Doppler metric associated with a wireless channel and a user equipment (UE). The Doppler metric may be determined from received information related to Doppler effects measured by the UE or from directly measured Doppler effects associated with uplink data received from the UE. Based on the determined Doppler metric, the base station may select one or both of a reference signal (RS) density and a channel estimation technique for the wireless channel and associated UE. The base station may transmit an indication of the RS density to the UE. Downlink data bursts and uplink data bursts may include RSs and data according to the indicated RS density. Further, the base station may transmit to the UE, an indication to communicate using the selected wireless channel estimation technique.

摘要： Methods, systems, and apparatuses for uplink descriptor channels are described. An uplink descriptor channel may be used by a user equipment (UE) for providing indications that uplink transmissions over allocated uplink data resources are sent in a configuration different from a configuration indicated by an uplink grant. In various examples an uplink transmission may be transmitted by a UE, and received by a base station, and the uplink transmission may include the uplink descriptor channel with uplink data. An uplink descriptor channel may include indications that uplink control information is included in the uplink transmission, and/or that the uplink transmission employs a number of transmission intervals, a number of channels, and/or a different MCS than those indicated by the uplink grant. A base station may receive the uplink descriptor channel and adjust various parameters of decoding an uplink transmission and/or allocating radio frequency spectrum resources.

摘要： A method to enhance coverage and/or throughput in a heterogeneous wireless network includes detecting interference between a neighboring cell and a serving cell. The method also includes cancelling the interference using an adaptive technique based on whether the interference has colliding Common Reference Signal (CRS) tones or whether the interference has colliding Dedicated Reference Signal (DRS) tones.

摘要： Channel clearance using a shared radio frequency spectrum band may be performed for both a base station and a user equipment (UE). A base station may perform a listen before talk (LBT) procedure and verify one or more channels in a shared radio frequency spectrum band are available for transmissions and, if the LBT procedure is successful, transmit a pre-grant transmission to one or more UEs. The UEs may perform an LBT procedure for channel(s) indicated in the pre-grant transmission. If the UE LBT procedure passes, the UE may transmit a channel clearance signal, and may transmit a feedback communication responsive to the pre-grant transmission. The feedback communication may indicate, for example, the pre-grant transmission was received and which of the one or more channels are available based on the LBT procedure. The base station may receive the feedback communication and initiate transmissions to the UE.

摘要： Embodiments include systems and methods for managing an adaptive interference filter performed by a device processor of a mobile communication device. A device processor may determine whether a transmission power from the mobile communication device is greater than or equal to a transmit power threshold. The device processor may determine whether a ratio of interference in a received signal to a level of the received signal including noise (interference ratio) is greater than or equal to an interference ratio threshold in response to determining that the transmission power is greater than or equal to the transmit power threshold. The device processor may perform interference cancellation with the adaptive interference filter in response to determining that the interference ratio is greater than or equal to the interference ratio threshold. In some embodiments the adaptive interference filter may be a non-linear interference cancellation filter.

摘要： Methods, systems, and devices are described for wireless communication. A transmitting device may send a signal including multiple transport blocks corresponding to multiple simultaneous hybrid automatic repeat request (HARQ) processes. Additional control information may be used to support the multiple simultaneous HARQ processes. For instance, the additional control information may indicate the number of available HARQ processes, an activity state for each HARQ process (e.g., active new data, active retransmission, or inactive), and the redundancy versions of each HARQ process. In some cases, the additional control information may be included in a downlink grant. A receiving device may respond with an acknowledgement or negative acknowledgment (ACK/NACK) for each of the transport blocks. The transmitting device may identify a retransmission status for each HARQ process based on the ACK/NACKs, and transmit new redundancy versions (or new data) to the receiving device.

摘要： Methods, systems, and devices are described for wireless communication. Wireless devices may exchange data using Medium Access Control (MAC) layer units known as transport blocks which may include a number of code blocks (CBs). A receiving device may attempt to decode each CB and send acknowledgement (ACK) and negative-acknowledgment (NACK) feedback to the transmitting device based on the whether each CB was successfully decoded. The receiving device may determine a format from two or more available formats for transmitting the ACK/NACK feedback. The format for the ACK/NACK feedback may be determined based at least in part on a number of CBs received and a number of CBs that have a NACK feedback. ACK/NACK feedback may be provided on an individual CB basis, or for bundles of CBs. The transmitting device may perform blind decoding of the received feedback to determine the ACK/NACK format and CBs that have NACK feedback.
