摘要： A method for rate adaptation with extended MCS set for wideband eigen-beamforming transmission. A signaling method over multiple channels in a wireless telecommunication system including a transmitter and a receiver, performs the steps of obtaining an information bit stream, selecting the number of transmission streams, selecting different transmission rates for each MIMO OFDM transmission, and transmitting the information bit stream from the transmitter via said multiple channels over a plurality of transmitter antennas to the receiver according to the selected transmission rate per channel. Selecting transmission rates further includes the steps of selecting the transmission rates based on the diversity order of each stream. The method selects different transmission modes for each MIMO OFDM transmission and provides a simple, fast and efficient scheme to select the transmission rate for each eigen-mode transmission.

摘要： A telecommunication MIMO receiver implements soft bit metric calculation with direct matrix inversion MIMO detection. The receiver has a detector that detects data symbols in a received signal by determining distances between received signal points and constellation points; a scaler that scales the distances using a scaling factor; and a soft bit metric calculator that uses the scaled distances to calculate scaled soft bit metrics. The receiver can also have a decoder that decodes the soft bit metrics to determine data values in the received signals. Preferably, the receiver also has a quantizer that dynamically quantizes the soft bit metrics before decoding by the decoder.

摘要： Systems and methods of providing a NPRACH preamble in a multefire system are described. A UE configured for multefire NB-IoT or eMTC operation receives, from an eNB, access information that includes a SIB on a narrowband channel of an unlicensed band. Based on the access information, the UE transmits a NPRACH preamble in two or six contiguous uplink subframes. The NPRACH preamble is transmitted in two or six contiguous subframes. When two subframes are used, four symbol groups each having a 266.7 μs CP and two symbols are transmitted without a gap therebetween. When six subframes are used, four symbol groups each having a 266.7 μs CP and five symbols are transmitted without a gap therebetween.

The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

摘要： Various embodiments include devices, methods, computer-readable media and system configurations for reference signal generation and resource allocation. In various embodiments, a wireless communication device may include a control module, which may be operated by a processor and configured to transmit to a user equipment (“UE”) device, over a wireless communication interface, a parameter specific to the UE device; wherein the parameter is usable by the eNB to generate a user equipment-specific reference signal (“UE-RS”) to be sent to the UE device. The parameter may be usable by the UE device to identify the UE-RS to facilitate demodulation of multiple-input, multiple-output communications. In various embodiments, a control module may be configured to store, in memory, priority rules, and to determine a UE-RS resource allocated to another UE device based on a UE-RS resource allocated to the UE device and the priority rules.

摘要： Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.
