Abstract: An apparatus comprising one processor and one memory including computer program code to: generate at least one sample corresponding to at least one radar/non-radar signal; form at least one spectrogram using time and frequency domain characteristics of the sample; wherein the spectrogram is formed via subdividing an observation window of the sample into time slots of a given duration, computing a power spectral density for a subset of the time slots having a higher determined energy relative to other time slots, and combining one or more computed power spectral densities of the subset; pass the spectrogram to a model to detect a presence of the radar signal and classify the radar signal as either interference/noise or radar present, and estimate a bandwidth of the detected radar signal; and determine the radar signal to be in-band or out-of-band relative to a shared spectrum hand, based on the estimated bandwidth.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A configuration to determine, by a user equipment, a random access procedure timeline, from multiple random access procedure timelines that each define a different duration between one or more messages that are communicated in a random access procedure can be determined or transmitted. A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: Architectures, methods and apparatus for providing data services (including enhanced ultra-high data rate services and IoT data services) which leverage existing managed network (e.g., cable network) infrastructure, while also providing support and in some cases utilizing the 3GPP requisite NSA functionality. Also disclosed are the ability to control nodes within the network via embedded control channels, some of which “repurpose” requisite 3GPP NSA infrastructure such as LTE anchor channels. In one variant, the premises devices include RF-enabled receivers (enhanced consumer premises equipment, or CPEe) configured to receive (and transmit) OFDM waveforms via a coaxial cable drop to the premises. In another aspect of the disclosure, methods and apparatus for use of one or more required NSA LTE channels for transmission of IoT user data (and control/management data) to one or more premises devices are provided.

Abstract: The present disclosure relates to transmitting transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available. Correspondingly, at the receiver, the grant is received (user equipment is receiver) or generated (base station is the receiver), the size of the subframe in which the reception is expected is determined and then the transport block is received with a modified modulation if only the partial subframe is available.

The apparatus is configured to sense and measure wireless communication signals from signal-emitting devices in a spectrum. The apparatus is operable to automatically detect a signal of interest from the wireless signal-emitting device and create a signal profile of the signal of interest; compare the signal profile with stored device signal profiles for identification of the wireless signal-emitting device; and calculate signal degradation data for the signal of interest based on information associated with the signal of interest in a static database including noise figure parameters of a wireless signal-emitting device outputting the signal of interest. The signal profile of the signal of interest, profile comparison result, and signal degradation data are stored in the apparatus.

Abstract: Disclosed herein is a method for transmitting, by a terminal, a sounding reference signal (SRS). The terminal receives a grant for uplink multiple subframes from a base station. The terminal determines a first subframe for an SRS transmission of the terminal among the uplink multiple subframes on the basis of SRS transmission position information received from the base station. Further, the terminal transmits the SRS in the first subframe.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses of transmitting information and receiving information in a wireless communication system. In the method of transmitting information, the information comprises at least two of a reference signal and more than one radio resource control (RRC) message. The method comprises transmitting the at least two of the reference signal and the more than one RRC message by using a same time unit or at least two continuous time units, wherein the at least two of the reference signal and the more than one RRC message have a same time offset or different time offsets and have a same transmission periodicity or transmission periodicities which are different multiples of a predetermined periodicity. Thus, the interference to other systems or nodes can be limited, and the number of LBTs required for these signal transmissions can be reduced if they are transmitted on unlicensed spectrum.
