  • Patent number: 10841938
    Abstract: A satisfactory latency-reducing effect is achieved when a plurality of transmission time intervals (TTI) of varying time durations are used in the same carrier. In this regard, a user terminal has a receiving section that receives scheduling information pertaining to a second TTI, which is shorter than a first TTI. The user terminal further has a control section that controls receipt and/or transmission of data in the second TTI, which is embedded in the first TTI, based on the scheduling information.

  • Patent number: 10833900
    Abstract: A receiver signal is sampled at a sampling rate equivalent to a chip rate at which chips of a known signal are timed. The resulting receiver signal samples are segmented into receiver signal segments, which are filtered by respective matched filters that are matched to known signal segments segmented from the known signal. Indexes are assigned to elements of the resulting filter response sequences to define an array thereof. Frequency transforms are computed of elements of the filter response sequences in respective columns of the array. Indexes are assigned to elements of the resulting frequency response sequences to define another array thereof. Channel effects imparted on a radio signal are jointly estimated from characteristics of the other array at which at least one local maximum is located.

  • Patent number: 10827375
    Abstract: A system and method for providing an eNodeB with the flexibility to configure a Channel State Information (CSI) report to match a specific Coordinated Multipoint (CoMP) transmission hypothesis, which is a candidate for a downlink transmission to a User Equipment (UE) is disclosed. A UE receives, from the eNodeB, a configuration message that specifies a CSI report. The CSI report is specified by a particular interference hypothesis and a particular desired signal hypothesis corresponding to data transmission over at least one effective channel characterized by a specific reference signal. The UE estimates interference according to the interference hypothesis, and/or estimates at least one effective channel by performing measurements on the specific reference signal, and determines a CSI report based on the interference estimation and on the estimated effective channel. The UE also transmits the CSI report to the eNodeB.

  • Patent number: 10803010
    Abstract: The system, products, and methods disclosed herein relate to an improved configuration for geographically dispersed data restart (“GDDR”) systems. Specifically, the teachings herein ensure a particular GDDR instance does not react to messages issued from address spaces outside of its affinity group. We use the term message “affinity group” to mean the combination of a particular GDDR instance and its set of Mainframe Enablers started tasks. By ensuring that the particular GDDR instance does not react to messages intended for recipients outside of its affinity group, we improve computer functionality and efficiency by facilitating further partitioning of the logical partition. Once the logical partition is further partitioned into additional address spaces, it is possible to run Mainframe Enablers and/or additional GDDR instances independent of the particular GDDR instance of concern.

In an example, the communications device generates a first digital signal based at least in part on an analog signal. The communications device also determines a second digital signal that corresponds to a predefined direct current (DC) signal. Further, the communications device generates a third digital signal based at least in part on the first digital signal and the second digital signal and compares a power estimate of the third digital signal with a power threshold. The power threshold is defined based at least in part on the predefined DC signal. The communications device determines that the analog signal corresponds to a data packet based at least in part on an outcome of the comparing.

  • Patent number: 10790889
    Abstract: Hybrid beamforming may be configured for wireless communication systems (e.g., multiple-input multiple output (MIMO) and/or massive-MIMO). The implementation(s) may determine a number of radio frequency (RF) chains for realizing a fully digital precoder (FDP) in a structure (e.g., a hybrid analog/digital precoder). The number of RF chains may be less than a number of transmitter antennas. A transmit vector signal may be determined based on a digital precoder and an input symbol vector. An analog precoder and/or a baseband signal may be determined based on the determined transmit vector signal. The number of RF chains may be determined based on the determined baseband signal. The baseband signal may be fed to the determined number of RF chains. The analog precoder may determine a beamforming signal based on an output of the determined number of RF chains. The analog precoder may transmit the beamforming signal using the number of transmitter antennas.
