20220109532 | CONTENTION WINDOW SIZE ADJUSTMENT FOR RETRANSMISSION OPERATIONS - Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for facilitating retransmission procedures in New Radio (NR) technologies. Some embodiments are directed to a method that includes determining a contention window size (CWS) of an uplink/downlink (UL/DL) communication channel in a new radio unlicensed (NR-U) spectrum. The method also includes adjusting the CWS based on: defining a reference UL/DL burst set at a predetermined time length independent from a subcarrier spacing and partially spanning an UL/DL burst, and counting one or more code block groups (CBGs) in the reference UL/DL burst. The method further includes scheduling a retransmission of an UL/DL communication in the NR-U spectrum based on the adjusted CWS. | 2022-04-07 |
20220109533 | TEST SYSTEM, ELECTRONIC DEVICE AND LOOPBACK TESTING METHOD - A test system for performing loopback tests is described. The test system includes a processing circuitry and loopback circuitry. The processing circuitry (e.g., module) includes a signal source, an artificial intelligence module, an output port, and an input port, wherein the output port is connected to the input port by the loopback circuitry. The signal source is configured to generate an output signal. The processing module is configured to output the output signal via the output port. The loopback circuitry is configured to at least one of transmit the output signal to the input port directly and transmit the output signal to the input port via at least one further electronic component, thereby obtaining at least one input signal. The input port is configured to receive the at least one input signal. The input port further is configured to forward the at least one input signal to the artificial intelligence module. The artificial intelligence module is configured to automatically perform a loopback test of at least one of the signal source and the further electronic component based on the at least one input signal.

20220109534 | UPLINK CONTROL INFORMATION REPORTING - Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit, from the mobile station to a base station, first uplink control information (UCI) associated with a first UCI stage using a time-frequency resource of a slot. The mobile station may transmit, from the mobile station to the base station, second UCI associated with a second UCI stage using the time-frequency resource of the slot. Numerous other aspects are provided. | 2022-04-07 |
20220109535 | METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND DEVICE FOR SUPPORTING SAME - Disclosed in various embodiments of the present disclosure are a method for transmitting and receiving a signal in a wireless communication system and a device for supporting same. | 2022-04-07 |
20220109536 | APPARATUS AND METHOD FOR PROTECTING AGAINST VICTIM MASQUERADE ATTACK IN REMOTE INTERFERENCE MANAGEMENT - Disclosed herein are system, method, and computer program product embodiments verifying legitimate victim-aggressor pairs in remote interference management operation. In an embodiment, a first even report is generated by a victim base station based detection of an atmospheric duct and it transmits a victim reference signal with the first event report. The first event report includes an ID of the victim base station. An aggressor base station is triggered to begin monitoring for transmission of the victim reference signal. The aggressor base station sends a second event report if it detects the victim reference signal. The central entity tries to verify that the victim and aggressor are legitimate. If the verification passes, then the central entity sends a message to the aggressor to start of remote interference mitigation. If verification fails, the remote interference mitigation is not triggered and the victim reference signal is ignored. | 2022-04-07 |
20220109537 | FREQUENCY SELECTIVE PHASE TRACKING REFERENCE SIGNAL (PTRS) ALLOCATION - This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enabling user equipment (UE) and a base station (BS) to communicate using a set of frequency resources in which a subset of frequency resources include a phase tracking reference signal (PTRS). In one aspect, the UE may measure the PTRS in the subset of frequency resources, and select a phase noise compensation that is used to demodulate a communication from the BS. The subset of frequency resources may be selected from the set frequency resources based on channel conditions of different subsets of frequency resources. The BS may provide an indication of the selected subset of frequency resources to the UE, such as in control information that schedules the communication from the BS. | 2022-04-07 |
20220109538 | SYSTEM AND METHOD FOR GENERATING REFERENCE SIGNAL WITH LOW PEAK AVERAGE POWER RATIO - A reference signaling scheme is provided that is based on the use of a Zadoff Chu sequence with cyclic repetition, optionally code division multiplexing precoding, together with frequency domain spectral shaping (FDSS). A specific pulse shape design for the FDSS part of the reference signal scheme in some embodiments involves the use of a raised cosine pulse raised to the power of β. The new solution for generating reference signals has a Low peak average power ratio that matches the PAPR of SC-OQAM, good channel estimation performance, and the ability to implement CDM in the frequency domain to increase multiplexing gain. | 2022-04-07 |
