TERMINAL, RADIO COMMUNICATION METHOD, AND BASE STATION
A terminal according to one aspect of the present disclosure includes: a receiving section that receives configuration information related to an uplink signal; and a control section that uses, in a case where the configuration information satisfies an application condition and quasi-co-location (QCL) type D in a transmission configuration indication (TCI) state for a downlink channel is not a periodic reference signal, a reference signal of at least one of QCL type A and the QCL type D in the TCI state, for calculation of a pathloss of the uplink signal. According to one aspect of the present disclosure, it is possible to appropriately transmit a UL signal.
RECEIVING METHOD, WIRELESS COMMUNICATION METHOD, RECEIVING STATION, WIRELESS COMMUNICATION SYSTEM, AND RECEIVING PROGRAM
A plurality of control signals transmitted in individual frequency bands by a moving transmission station via a plurality of transmission antennas and a plurality of data signals transmitted in a common frequency band by the transmission station via the plurality of transmission antennas in synchronization with the control signals are received by each of a plurality of antennas disposed at different positions. Based on symbol timings of the control signals received by the antenna, a sampling rate error between the plurality of control signals transmitted by the plurality of transmission antennas, respectively, is compensated for. Based on the control signals subjected to the sampling rate error compensation, frame timings of the plurality of data signals transmitted by the transmission station via the plurality of transmission antennas are synchronized. Based on the control signals subjected to the sampling rate error compensation, channels for the plurality of data signals transmitted by the transmission station via the plurality of transmission antennas are estimated. The plurality of data signals with the frame timings synchronized, for the estimated channels are equalized.
NON-STANDALONE ARCHITECTURE FRAME ALIGNMENT
Techniques for measuring and reducing signal misalignment in a dual connectivity environment are discussed herein. When using Non-Standalone Architecture (NSA), a device initially communicates with a network using a Long-Term Evolution (LTE) connection. After the LTE connection is established, an LTE base station may instruct the device to measure signal strength of a neighboring New Radio (NR) cell during a specified LTE measurement gap. When the NR cell is implemented by an indoor NR base station, the NR signal may not be sufficiently synchronized with the LTE signal and the device may be unable to measure the NR signal during the measurement gap. In these cases, the device can determine the frame timing difference between the LTE and NR signals, obtain an adjusted measurement gap that reduces any measurement gap misalignment, and attempt to measure the signal strength of the NR cell using the adjusted measurement gap.
TECHNIQUES FOR HANDLING OVERLAPPING TRANSMISSIONS AFTER TIMING ADJUSTMENT
Aspects described herein relate to receiving a timing adjustment (TA) command indicating to adjust timing for an uplink transmission in a time division, adjusting, by the UE and based on the TA command, the timing for the uplink transmission in the time division, and where the uplink transmission includes an overlapping portion that at least partially overlaps in time with a previous uplink transmission scheduled for transmission in a previous time division, due to the TA command, and a non-overlapping portion that does not at least partially overlap in time with the previous uplink transmission, refraining from transmitting the non-overlapping portion of the uplink transmission that is scheduled in the time division. Other aspects relate to transmitting the TA command and not receiving an overlapping uplink transmission.
MEASUREMENT DEVICE AND MEASUREMENT METHOD
A network measurement device includes a setting control unit that sets, for example, a single GNSS as a transmission source of a signal of a multi-band, a multi-band abnormality detection unit that detects a multi-band reception abnormality based on an existing GNSS antenna receiving a signal in the multi-band transmitted from the GNSS, which is the transmission source, and reception signal information obtained by reception processing in a state in which the network measurement device is connected to the apparatus of a moving destination, for example, a boundary clock, and the existing GNSS antenna is connected to an antenna input terminal, for example, and an alert notification control unit that notifies a user of an alert notification that a multi-band reception abnormality occurs when a multi-band reception abnormality is detected.
Radio link failure recovery
Apparatuses, methods, and systems are disclosed for radio link failure recovery. One method includes determining, at a first user equipment, an occurrence of a radio link failure with a second user equipment. The method includes transmitting information indicating the radio link failure. The method includes starting a timer in response to transmitting the information indicating the radio link failure. The method includes, after starting the timer and before the timer expires, transmitting one or more messages to the second user equipment requesting feedback from the second user equipment.
Building management system for sensor time correction
A building management system and method for sensor time correction is described. The system comprises multiple sensors and an energy manager communicating with the sensors. The sensors, distributed within a particular area, provide multiple time measurements in response to detecting an object traversing among the sensors in which the time measurements are associated with unsynchronized time. The energy manager identifies a predicted time for traversing among the sensors based on one or more distances between pairs of sensors and an average velocity of the object to traverse among the sensors. The energy manager determines a sensor time error for each sensor by cross-correlating the time measurements with the predicted time.
Synchronization signal periodicity adjustment
Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.
WIRELESS TIMING ADJUSTMENT FOR PERIODICAL TRAFFIC OF MULTIPLE TIME DOMAINS
A communication terminal is provided for supporting a periodical data flow by forwarding messages received from a communication network to an external node not synchronised with the communication network. The communication terminal is configured to obtain one or more timing adjustment indications from an access node of the communication network and adjust the transmission and/or reception timing of the periodical data flow in dependence on the timing adjustment indication(s). The one or more timing adjustment indications are based on clock mismatch information between the communication terminal and the external node and a holding time.
