    摘要： The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a UE is provided. The method includes receiving, from a base station, first information of a timer associated with bandwidth part (BWP) inactivity; receiving, from the base station, physical downlink control channel (PDCCH) on an active BWP associated with a serving cell; identifying whether there is ongoing random access procedure associated with the serving cell; and starting or re-starting the timer in response to identifying that there is no ongoing random access procedure associated with the serving cell.

    摘要： A communication method disclosed in the present disclosure includes: receiving, by an access point, a sending request sent by a first station, and sending clear to send information to the first station; when the access point receives feedback information sent by the first station, allocating, by the access point, a channel to the first station, and allocating a channel to a second station based on remaining bandwidth; generating a first trigger frame, and sending the first trigger frame to the first station and the second station; and receiving uplink data sent by the first station and the second station. The present disclosure further provides an access point and a station that can implement the communication method. According to the present disclosure, bandwidth utilization of the access point and data transmission efficiency can be improved.

    摘要： The present invention provides a computer implemented method, system, and computer program product of optimizing bandwidth of cognitive radios (CRs). In an embodiment, the present invention includes monitoring use of channels of digital wireless spectrum by at least one primary user communications device (PU device), resulting in PU activity data describing the use, using a digital wireless spectrum channel with a lowest usage by the at least one PU device as indicated by the PU activity data, detecting when the at least one PU device begins to use at least one digital wireless spectrum channel, calculating TCP connection data describing a plurality of TCP connections in light of TCP connection parameter data, and performing a network congestion-avoidance algorithm using the calculated TCP connection data, resulting in digital wireless transmission characteristics for at least one of the plurality of TCP connections that are optimized for at least one CR device.
