    Abstract: A technique includes receiving, by a user device, a configuration of a set of one or more resources for an uplink channel to be used for transmission by the user device in a slot prior to a short physical uplink control channel of the slot; receiving, by the user device, a downlink control information including a downlink assignment for a downlink channel; identifying, by the user device based on the downlink assignment, a resource of the set of one or more resources for the uplink channel, and a physical uplink control channel; and transmitting, by the user device, a signal via the identified resource for the uplink channel, prior to the short physical uplink control channel of the slot.

    Abstract: Solutions for determining a resource for transmitting/detecting an uplink (UL) control signal are proposed. For example, a method includes receiving a physical resource configuration and/or an assigned resource indicator for transmitting the UL control signal, wherein the physical resource configuration indicates a plurality of resources in frequency domain. The method also includes determining a resource based on the received physical resource configuration and/or the assigned resource indicator; and adjusting the determined resource for transmitting the UL control signal based on at least one of an outcome of downlink (DL) listen before talk (LBT) performed prior to the transmission of the UL control signal, an outcome of UL LBT performed prior to the transmission of the UL control signal, and a time gap between the UL LBT and the transmission of the UL control signal.

    Abstract: Multiplexing of information may be useful in a variety of communication scenarios, such as communication of control information. For example, certain wireless communication systems may benefit from uplink control information multiplexing for downlink two orthogonal frequency division multiplexed symbol short transmission time interval and one millisecond transmission time interval. A method can include receiving, at a user equipment, a downlink assignment scheduling first downlink data transmission in a first transmission time interval duration. The method can also include determining when to provide acknowledgment feedback in an uplink corresponding to the scheduled downlink data transmission. The determination can take into account whether the user equipment is scheduled for downlink data transmission in a second transmission time interval duration. The second transmission time interval duration can be shorter than the first transmission time interval duration.
