In one aspect, a wireless device receives a scheduling grant and a grant confirmation signal indicating that a network node has performed a CCA on a carrier and is releasing the carrier for the wireless device. An uplink message is transmitted on the carrier without performing a CCA on the carrier. In another aspect, a wireless device is connected to a first cell and a second cell configured on a carrier requiring an LBT protocol. The wireless device receives configuration messages indicating that downlink transmissions on the second cell are to be scheduled. This can mean self-scheduling for downlink on the second cell and cross-carrier scheduling for uplink on the first cell. The wireless device receives a scheduling grant in the first cell and performs a CCA in the second cell. The wireless device then transmits an uplink message responsive to success of the CCA.

Scheduling in license assisted access

According to certain embodiments, a method for use in a wireless device for transmitting uplink control information (UCI) on grant-free resources comprises reserving a subset of time/frequency resources of a grant-free uplink channel for transmitting UCI, and upon determining the wireless device has UCI to transmit on the grant-free uplink channel, transmitting the UCI to a network node in the reserved subset of time/frequency resources.

UCI on grant-free PUSCH

There is disclosed a method of operating a terminal () in a wireless communication network, the method comprising receiving and/or transmitting according to a transmission time interval, TTI, configuration, the TTI configuration indicating at least one short transmitting time interval having between one or two and seven symbols of duration in a subframe. There are also disclosed related methods and devices.

Short TTI patterns

According to certain embodiments, a method by a wireless device is provided for transmitting uplink control information (UCI) on a serving cell on the unlicensed spectrum. The method includes formatting the UCI as a shortened control signalling transmission and transmitting the UCI formatted as the shortened control signalling transmission to a network node. The shortened control signalling transmission is transmitted during a transmission opportunity on the serving cell on the unlicensed spectrum without performing channel sensing.

Systems and methods for uplink control information signaling design

According to an aspect, a transmitting device determines, for each of a plurality of transmissions, whether user data to be transmitted within a time transmission interval, TTT, will be closest in time to a DMRS transmitted before the user data or after the user data. If before the user data, all HARQ ACK/NACK data for the transmission is mapped to the earliest in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted before the user data. If after the user data, all HARQ ACK/NACK data for the transmission is mapped to the last in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted after the user data. SC-FDMA signals are formed from user data and control information for the transmission, based on the mapping.
