Abstract: Systems and methods for uplink cancellation are provided. In some embodiments, a method performed by a wireless device for performing uplink cancellation includes receiving an indication to stop a transmission; and receiving an indication to transmit on cancelled uplink resources. In some embodiments, in response to receiving the indication to stop the transmission, performing one of: cancelling the transmission; and muting the transmission. In this way, the New Radio (NR) Uplink (UL) cancellation mechanism can be enabled on NR-Unlicensed (NR-U) resources and helps to cater Ultra-Reliable and Low Latency Communication (URLLC) services.

Abstract: A network-based method allows a network to optimize its control of radio resource usage by directing connected and idle mode User Equipment (UEs) (10) to another network node, e.g. a neighbor cell, having a better duty cycle, or by configuring the UEs to use another frequency band served by the same network node or a different network node. Signaling its duty cycle budget to the UEs allows the UEs to optimize their idle mode operation by performing cell re-selection to a network node which has a better duty cycle budget.

Abstract: According to an aspect, a wireless device identifies system frame numbers (SFNs) that are used for wireless transmissions that use a broadcast channel (BCH) transmission time interval (TTI), where frequency hopping cycles (FHCs) are not aligned with a cycle of the SFNs. The wireless device receives FH information indicating how the FHC used for wireless transmissions relates to the SFN cycle and identifies an SFN timing for the wireless transmissions based on the FH information.

Abstract: Systems and methods for frequency hopping random access in a wireless network that operates in an unlicensed frequency spectrum are disclosed. In some embodiments, a method performed by a wireless device comprises determining that a network node is inactive for a first dwell time, where the first dwell time is a first period of time during which the network node operates on a first frequency, and transmitting a random access preamble during the first dwell time. The method further comprises determining that the network node is active for a second dwell time, where the second dwell time is a second period of time during which the network node operates on a second frequency. The method further comprises, upon determining that the network node is active for the second dwell time, monitoring for a random access response in the second dwell time.

Abstract: In one aspect, a wireless device monitors radio link quality for a link between the wireless device and a wireless transmitter that is configured to transmit a discovery signal at spaced, periodic, intervals and that is further configured to intermittently transmit subframes carrying user data, such that the wireless device is unable to predict which subframes will carry user data before attempting to detect the subframes. The wireless device collects, for each of the spaced, periodic, intervals, discovery-signal signal quality metrics corresponding to the discovery signal. The wireless device also collects, for each detected subframe carrying user data, detected-subframe signal quality metrics corresponding to the detected subframe. The wireless device generates, for each of a plurality of evaluation intervals, an in-synch or out-of-synch indication, based on a combination of the discovery-signal signal quality metrics corresponding to the evaluation interval and the detected-subframe signal quality metrics corresponding to the evaluation interval.

Abstract: New signaling is defined from wireless devices (10) to a wireless communication network,concerning the wireless devices' duty cycle statuses. This allows the network to optimize its control of the radio resource usage. Additionally, embodiments described herein provide new signalling from the network to wireless devices concerning the network's duty cycle status. This allows wireless devices (10) to optimize their idle mode operation, including decisions whether to request a connection setup or remain in idle mode. Embodiments described and claimed herein provide a set of simple methods for operating a cellular system in a duty cycle controlled radio frequency band.
