Title: OPPORTUNISTIC ASYNCHRONOUS OPERATION FOR COORDINATED NR-SS
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.
