摘要： According to the present disclosure, behaviors of User Equipment (UE) and base station (BS) pertinent to Scheduling Request (SR) and/or Buffer Status Report (BSR) as well as resource management in short Transmission Time Interval (sTTI) relevant scenarios are discussed. UE may firstly determine if the SR is triggered by a buffer status change of a delay-critical data which needs a sTTI. If so, UE will send the SR to BS on a first type of uplink control channel designed for sTTI. Otherwise, UE will send the SR to the base station on a second type of uplink control channel designed for legacy TTI.

摘要： Methods, network nodes and wireless devices configured for resource allocation to a wireless device are disclosed. According to one aspect, a method includes selecting at least one of a common bandwidth scheme and a common power scheme. If the selected at least one scheme includes a common bandwidth scheme, a common bandwidth to be used by the wireless device for transmission of two data channels in two successive short transmission time intervals, sTTIs, that share a common demodulation reference signal, DMRS, is determined. An indication of the common bandwidth to the wireless device to enable the wireless device to set the bandwidth of the two data channels to a common bandwidth value is sent. If the selected at least one scheme includes a common power scheme, then a common power control command to control an output power to be set by the wireless device for two data channels in two successive sTTI, that share a common DMRS is determined. The common power control command to the wireless device to enable the wireless device to set the output power of the two data channels to a common power value is sent.

摘要： A method performed by a transmitting node (110; 120) for performing data transmissions to at least one receiving node (120; 110) on a radio channel in a wireless communications network (100) is provided. First, the transmitting node sets at least two contention window sizes, wherein the at least two contention window sizes are separately determined based on information associated with the least one receiving node. Then, the transmitting node defers a first transmission of data to the at least one receiving node (120; 110) for a first period of observation of the radio channel determined by a first contention window size of the at least two contention window sizes. The transmitting node also defers at least one second transmission of data to the at least one receiving node (120; 110) for at least one second period of observation of the radio channel determined by at least a second contention window size of the at least two contention window sizes. Further, the transmitting node performs the first or the at least one second transmission of data to the at least one receiving node (120; 110) when an outcome of the first or the at least second periods of observation of the radio channel, respectively, is that the radio channel is idle. A transmitting node (110; 120) and a computer program product for performing data transmissions to at least one receiving node (120; 110) on a radio channel in a wireless communications network (100) are also provided.

摘要： According to some embodiments, a network node in a frequency division duplex (FDD) wireless communication network is operable to schedule a first downlink transmission with a first transmission processing time on a first frequency carrier. The scheduling comprises a first downlink assignment index (DAI). The first DAI comprises a first total DAI and a first accumulative DAI. The network node is operable to schedule a second downlink transmission with a second transmission processing time different than the first on a second frequency carrier. The scheduling comprises a second DAI. The second DAI comprises a second total DAI and a second accumulative DAI. The network node expects hybrid automatic repeat request (HARQ) feedback for the first downlink transmission and the second downlink transmission in a single uplink transmission. The network node is further to transmit the scheduling for the first and second downlink transmission to a wireless device.
