摘要： A technique for performing a multi-layer transmission from a transmitting station to a receiving station on a radio frequency is described. The multi-layer transmission comprises multiple layers having different robustnesses (704, 706) on the radio frequency. As to a method aspect of the technique, first data of a first hybrid automatic repeat request, HARQ, process is transmitted on a first layer of the multi-layer transmission simultaneously with second data of a second HARQ process on a second layer of the multi-layer transmission.

摘要： Embodiments herein relate to a communication terminal (10) for handling communication, which communication terminal (10) is being served by a radio access node (12, 13) in a first cell (11) on a carrier of a licensed frequency spectrum and cross-carrier scheduled in a second cell (14) on a carrier of an unlicensed frequency spectrum by the radio access node (12, 13) via the first cell (11). The communication terminal receives an indication that data may be scheduled for the communication terminal (10) on a data channel in the second cell (14). The communication terminal attempts to detect presence of the data channel intended for the communication terminal (10). Then, in case the communication terminal (10) detects presence of the data channel intended for the communication terminal (10), the communication terminal (10) decodes the data channel. In case the communication terminal (10) does not detect presence of the data channel intended for the communication terminal (10), the communication terminal (10) indicates a non-detection of the data channel to the radio access node (12, 13).

摘要： Channel state determination is performed at a user equipment (UE) of a mobile network. The UE determines one or a plurality of time intervals that may be used for channel measurements, performs a plurality of signal power measurements associated each to one of the time intervals to be used for channel measurement and generates a channel state information as a function of the plurality of the signal power measurements. Information comprising an indication of a plurality of time intervals that may be used for received signal power measurements is generated and sent from an access node (eNB) to the UE. The eNB evaluates a measurement report, received from the UE, that comprises received signal power measurements associated each to one of the time intervals.

摘要： An example method is performed by a wireless device in a wireless communication network. The method comprises receiving, from a base station, a control message allocating resources in a bandwidth part for a downlink transmission, the bandwidth part including unlicensed spectrum and being divided into a plurality of bandwidth pieces corresponding to bandwidth units over which listen-before-talk (LBT) is performed. The radio resources used for the downlink transmissions exclude (e.g., by puncturing or rate-matching around) one or more guard bands of a bandwidth piece that is sensed as free for transmission.

摘要： The present disclosure described systems and methods for providing OTT services to a UE. An exemplary OTT-providing host computer includes a transceiver, a processor, and memory collective configured to provide the OTT service by initiating transmission of user data to the UE. To transmit the user data from the host computer to the wireless device, a network node sends a first control message for assigning a PDSCH, the first control message comprising a first MCS indication as described. The network node sends to the wireless device a second control message for assigning a PDSCH, the second control message comprising a second MCS indication as described. The network node transmits the user data thereafter.

摘要： Methods and arrangements for determining a next interlace having a next structure to be applied during a next transmission interval in an unlicensed spectrum are disclosed. The next structure is to be applied for a transmission over a wireless interface in a wireless communications network operating in an unlicensed spectrum, wherein a first interlace is applied during transmission in a first transmission interval and wherein the first interlace has a first interlace structure formed by a plurality of physical resource blocks, PRBs, that are arranged with a given subcarrier spacing in one of a set of interlaces. The method includes defining a frequency shift based on the number of PRBs per interlace and a maximum allowed power for a single interlace and determining the next interlace structure by shifting the first interlace structure by the defined frequency shift.
