Abstract: An opportunistic asynchronous operation for coordinated new radio (NR) shared spectrum (NR-SS) operations is discussed. In a wireless network having at least one contention-based shared channel in which communications are configured having one or more control intervals time division multiplexed with one or more data intervals for transmission opportunities, a base station receives data for communication at a time during a current data interval on a contention-based shared channel. The base station will review its received signals on the contention-based shared channel during the previous control interval located immediately prior to the current data interval. If none of the received signals indicate a contention-resolution of the contention-based shared channel, the base station may begin an attempted transmission by performing an abbreviated clear channel assessment (CCA). If the CCA is detected as clear, the data may be transmitted.

Abstract: A base station includes a transmitter which transmits an offset value for a transmission power of a sounding reference signal (SRS) to a terminal apparatus; and a receiver which receives the SRS at the transmission power controlled by the terminal apparatus. The offset value used to control the transmission power is set within one of a first offset setting range having a first lower limit value and a first upper limit value and a second offset setting range having a second lower limit value and a second upper limit value. A difference between the first and second lower limit values equals a difference between the first and second upper limit values. A step width of the offset values within the first offset setting range equals a step width of the offset values within the second offset setting range. The SRS is a periodic SRS (P-SRS) or an aperiodic SRS (A-SRS).

Abstract: A system, computer-implemented method and computer program performs heartbeat messaging for managing connections for data communications. In one example method, an indication of a problem associated with a connection for data communication in a computing system or network is received. In response to receiving the indication, a heartbeat message is sent over the connection. The method monitors for a heartbeat response to the heartbeat message within a predefined heartbeat time interval. If a heartbeat response is received within the predefined heartbeat time interval, the method determines that the indication of a problem associated with the connection is invalid. If a heartbeat response is not received within the predefined heartbeat time interval, the method determines that the indication of a problem associated with the connection is valid.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a timing configuration that includes a time delay between uplink and downlink communications. The time delay may be based on UE capabilities, scheduling in the system, and an uplink timing advance.

Multiple timing advance thresholds may be used, and a timing configuration may be selected accordingly.
