摘要： Systems and methods are disclosed for enhanced transmit and receive performance for time synchronization. In one embodiment, a method performed by an access node for a wireless network comprises receiving a Physical Random Access Channel (PRACH) preamble from a User Equipment (UE) and deriving timing-related information based on the PRACH preamble in accordance with a defined uplink signal timing detection error requirement, the defined uplink signal timing detection error requirement being stricter than a respective uplink signal timing detection error requirement defined in Release 15 and 16 of Third Generation Partnership Project New Radio (NR) specifications for a subcarrier spacing used for the PRACH preamble. The method further comprises sending the timing-related information to the UE. In this manner, enhanced time synchronization performance can be achieved.

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with a frequency hopping pattern for communication between the UE and a base station, and also may be configured with a measurement gap pattern for measurement of one or more reference signals from one or more neighboring base stations. One or more switching timings of a set of switching timings of the frequency hopping pattern may be aligned with a reference point associated with the measurement gap pattern, which may provide aligned switching gaps in the frequency hopping pattern and the measurement gap pattern.

摘要： Methods, systems, and devices for wireless communications are described that asynchronous carrier aggregation, including between high frequency band and lower frequency band transmissions. A user equipment (UE) may be configured to monitor transmissions in a first frequency band and a second frequency band. The UE may measure a timing difference between transmissions in the first frequency band and one or more of the transmissions in the second frequency band, and transmit an indication of the timing difference to a base station. The base station may use the timing difference to determine whether the UE is to use asynchronous carrier aggregation. If the base station determines that the UE is to use asynchronous carrier aggregation, the base station may configure the UE to observe at least a minimum amount of delay when conducting uplink signaling via one of the frequency bands.

摘要： TDD configuration may be dynamically and/or semi-statically signaled to user equipment devices by a base station. Semi-static TDD configuration may include: an initial portion for downlink transmission; a flexible portion; and a terminal portion for uplink transmission. TDD structure of the flexible portion may be determined later by transmission of dynamic physical layer configuration information such as downlink control information (DCI) and/or slot format indicator (SFI). (The SFI may be included in a group common PDCCH of a slot.) The downlink portion and/or the uplink portion may include subsets whose nominal transmit direction is subject to override by transmission of dynamic physical layer configuration information.
