摘要： A method for interference coordination comprises receiving, from a first network node, a reference signal indicating that one or more second network nodes are experiencing interference. The reference signal indicates at least one identifier for the first network node and for the second network nodes. The method further comprises preparing a remote interference management (RIM) coordination message based on the reference signal, and sending, to the first network node, the RIM coordination message to be forwarded to the second network nodes. The method provides a communication between a central aggressor network node and a central victim network node to exchange reference signal and RIM coordination information. Furthermore, the central victim network node may pass the RIM coordination message to a group of victim network nodes indicated in the RIM coordination message.

摘要： Embodiments include methods for a user equipment (UE) to transmit control information in association with a plurality of data packet repetitions. Such methods include selecting, from a plurality of configured starting transmit positions, a starting transmit position for an initial repetition of the plurality. Such methods include selecting a sequence of cyclic shift (CS) values from a plurality of configured CS values. The plurality of configured CS values are less than the plurality of repetitions and/or the plurality of configured starting transmit positions. The sequence is selected based on the plurality of repetitions, and on an identifier associated with the data packet and/or the selected starting transmit position. Such methods include transmitting the data packet repetitions beginning at the starting transmit position, wherein at least a subset of the repetitions are transmitted in association with demodulation reference signals (DMRS) that are cyclic-shifted according to CS values of the selected sequence.

摘要： A method, wireless device and network node for regulating power to be allocated to transmission time intervals, TTIs, are disclosed. In one embodiment, a wireless device supports short TTIs of duration less than a subframe, and for each of at least one TTI to be transmitted during a subframe, the wireless device allocates a power Pn at which to transmit during the TTI, such that the total of all power allocations at a pre-determined time interval is less than a maximum power Pmax.

摘要： The user equipment 12a and 12D comprises a radio transmitter 76 arranged to transmit data packets to the receiver 71 of the communication network entity 16 over the radio interface on the uplink channel 11 and a receiver 77 arranged to receive data packets transmitted from the transmitter 72 of the communication network entity 16 on the downlink channel 13. The user equipment 12a and 12b further comprises means 78 for analysing said received data packets as described above and in conjunction with fig. 6. Thus, while there have been shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognised that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. Expressions such as "including", "comprising", "'incorporating", "consisting of", "have", "is" used to describe and claim the present invention are intended to be construed in a nonexclusive manner, namely allowing for items, components or elements not explicitly described also to be present. Reference to the singular is also to be construed to relate to the plural and vice versa. Numerals included within parentheses in the accompanying claims are intended to assist understanding of the claims and should not be construed in any way to limit subject matter claimed by these claims.

摘要： A method and associated apparatus for preserving frequency spectrum in a linear modulation scheme, by adding a compensation signal to a modulated signal, the compensation signal having the same spectrum as the modulated signal. In the present invention, peaks above a pre-determined maximum threshold and/or minima below a pre-determined minimum threshold are searched. When a peak is found, the amount by which the signal peak exceeds the maximum threshold, as well as the signal phase at the peak is calculated. A compensation signal is generated with the same peak amplitude as the signal exceeds the maximum threshold, and with opposite phase. Then the shape of the compensation signal is chosen to be the same as the transmitter pulse of the modulated signal. Finally, the compensation signal is added to the modulated signal.
