摘要： A method performed by a wireless device 410 is provided for receiving an uplink scheduling grant for a plurality of physical uplink shared channels (PUSCHs). The method includes receiving, from a network node 460, downlink control information (DCI). The DCI includes an indication corresponding to at least a time domain resource for each of the plurality of PUSCHs. Based on the indication, uplink scheduling grant resources are determined for the plurality of PUSCHs. At least one transmission is sent according to the determined uplink scheduling grant resources.

摘要： Performing an unscheduled uplink transmission by a user equipment, UE, in an unlicensed portion of a radio spectrum, the method comprising: performing (1002), by the UE, a listen before talk, LBT, operation in the unlicensed portion of the radio spectrum, wherein the LBT operation includes sensing the portion of the radio spectrum for a pre-determined minimum amount of time for traffic; and performing (1004), if no traffic was sensed, the unscheduled uplink transmission, by the UE, of data in an unscheduled mode of operation for at least one transmission burst. Receiving (10110) by the UE an uplink transmission grant. In response to receiving the grant, transmitting, by the UE, an uplink transmission burst of new data, and sending (1012), by the UE, an unscheduled retransmission for the data if a new uplink grant or HARQ ACK/NACK is not received from an eNB within a pre-specified time window.

摘要： A radio device (10; 900; 1200) receives control information from a node (100; 1100; 1300) of the wireless communication network via a Radio Resource Control message. The control information is used for controlling semi-persistent allocation of radio resources of an unlicensed frequency spectrum. The control information defines a first configuration applicable for a first uplink carrier and a second configuration applicable for a second uplink carrier. At least one of the first uplink carrier frequency and the second uplink carrier frequency is from the unlicensed frequency spectrum. The radio device sends in a control element of a Medium Access Control protocol, unlicensed spectrum semi-persistent scheduling grant confirmation information to the node of the wireless communication network, the unlicensed spectrum semi-persistent scheduling grant confirmation information consisting of at least one multi-bit value, wherein each bit of the multi-bit value indicating individually for each of the first and second uplink carrier whether semi-persistent allocation of radio resources is activated. Based on the control information, the radio device controls at least one UL radio transmission on the radio resources of the unlicensed frequency spectrum.
