Abstract: A UE performs first control channel monitoring according to a first CORESET and first search space set configuration(s), the first control channel monitoring performed on n subbands, n>1, able to be transmitted by a base station in an unlicensed band carrier. The UE determines, in response to a detection of a control channel in the monitoring and from the control channel, transmission bandwidth configuration to be used by the base station in the unlicensed band carrier for control channels. The UE performs second control channel monitoring according to a second CORESET and at least one second search space set configuration. The second control channel monitoring is performed on m subbands, m≤n, in the unlicensed band carrier, the m subbands being a subset of the n of subbands. A base station determines which subbands are available for use and transmits the transmission bandwidth configuration to the UE based thereon.

Abstract: Various communication systems may benefit from a reduction in latency. For example, communication systems may benefit from an improved transmission of an uplink reference signal in an uplink channel. A method, in certain embodiments, includes determining by a user equipment a candidate location of a transmission of an uplink reference signal in a channel. The method also includes determining by the user equipment a triggering window associated with the candidate location of the transmission of the uplink reference signal in the channel. In addition, the method includes receiving an uplink grant for a data transmission from a base station. Further, the method includes transmitting the uplink reference signal based on the uplink grant being at least partially within the triggering window.

Abstract: A method comprises transmitting from a user device information on first and second hybrid automatic request acknowledgement bits and a scheduling request in a same transmission time interval. The information on said first and second hybrid automatic request acknowledgement bits and said scheduling request are transmitted via first and second physical resource blocks using one or more resources of a set of resources. At least one of the resources of the set of resources differs from the one or more resources of the set of resources used to transmit information on the first and second hybrid automatic request acknowledgement bits when there is no scheduling request.

Abstract: Various communication systems may benefit from appropriate coordination of measurements for mobility or other reasons. For example, Long Term Evolution communication systems may benefit from signaling for uplink short transmission time interval transmissions. A method can include determining how a user equipment is to transmit with respect to a demodulation reference signal. The method can also include providing uplink grant to schedule the user equipment to transmit according to the determination.
