Methods in a radio network node (110) and a user equipment (120) as well as a radio network node (110) and a user equipment (120) for providing access restriction information about restricting access to a cell (C1), managed by the radio network node (110), for at least the user equipment (120) are provided. The radio network node (110) encodes a downlink control information message by using a user equipment identifier associated with the access restriction information. Next, the radio network node (110) sends the downlink control information message to the user equipment (120). Next, the user equipment (120) decodes the downlink control information message to obtain the user equipment identifier associated with the access restriction information.

The wireless device 3 is adapted for wireless communication in a communication system 1 comprising a network node 2. The method 10 comprises: receiving 11, from the network node 2, a downlink transmission, the downlink transmission comprising a transmission parameter used for the downlink transmission; measuring 12 channel quality of the received downlink transmission; determining 13, based on the measured channel quality, a transmission parameter, that the wireless device 3 is able to support; correlating 14 the transmission parameter used for the downlink transmission with the determined transmission parameter, giving a correlated transmission parameter; and encoding 15 the correlated transmission parameter together with Hybrid Automatic-Repeat-Request feedback information.

The herein suggested technology gives principles for how HARQ-feedback, or corresponding, can be predicted using distributed data from scheduling decisions and optionally also from radio measurements. This data can be sent between base stations after the finished scheduling, and does not require a backhaul with very low latency. The predicted HARQ feedback can then be used for scheduling a retransmission or new transmission sooner than the actual HARQ feedback is received.

A method and an arrangement (400, 600) in a first and second node, respectively, are provided. In a step (220), the first node (110) sends a plurality of resource units in a time period on a combined feedback and data channel. Said plurality of resource units comprises information about feedback data and user data. At least a minimum number of resource units are reserved for allocation by the user data.

A method and arrangement are disclosed in a Vector Control Entity for enabling a fair bit rate distribution among lines of similar priority in a vectoring group, when applying partial vectoring in a DSL communication system. The method comprises calculating a rate balancing metric, RBM, for each line i within a priority group A, indicative of the ratio between the bit rate of a line i with a current vectoring resource allocation, and the estimated bit rate of line i assuming approximately no crosstalk within the vectoring group. The method further comprises allocating partial-vectoring resources to the line/s within the group A, based on the calculated RBMs, such as to reduce the difference in RBM between the lines. The method further comprises calculating an updated RBM for any line within the group A subjected to changes in vectoring resource allocation. The method may be iterated until certain criteria are fulfilled. The arrangement is adapted to enable the performance of the above described method.
摘要:
The teachings herein disclose methods (600, 700) and apparatuses (36, 50) for dynamically rescheduling retransmissions from a selected Hybrid Automatic Repeat reQuest, “HARQ”, process, based on temporarily remapping the selected HARQ process to one or more subframes (12) that are by default scheduled for another HARQ process running synchronously with the first HARQ process. One advantage of dynamic rescheduling is that a retransmission for a given HARQ process can be accelerated in time, as compared to when the retransmission would occur absent the remapping. In another advantageous aspect, in at least some embodiments, the control signalling (20) for dynamic rescheduling is included in the Downlink Control Information, “DCI”, used to send scheduling grants for the HARQ processes, such that dynamic rescheduling uses control signalling (20) that is compatible with existing scheduling grant signalling.

A method for reducing vortex formation in molten metal when bottom tapping the molten metal from a metallurgical vessel in a metal making process. The method includes the steps of tapping the molten metal via a tapping hole in the metallurgical vessel, and providing a flow of the molten metal in the metallurgical vessel while tapping via a time-varying electromagnetic field applied to the metallurgical vessel, the flow of the molten metal being such that it constantly moves vortices in the molten metal away from a tapping hole region during the tapping to thereby prevent accumulation of the vortices for vortex formation over the tapping hole. It is also presented an arrangement for carrying out the method.

Embodiments herein relate to a method in a radio base station for transmitting an information signal in a radio communications network. The radio base station is arranged to operate in a time structure associated with a clock and arranged to transmit an information signal associated with the time structure. The radio base station is in the radio communications network. The radio base station transmits the information signal repeatedly with a first frequency over a first period of time. Then, the radio base station transmits the same information signal repeatedly with a second frequency over a second period of time, wherein the first frequency is lower than the second frequency and the first period of time is longer than the second period of time.
摘要:
When data retransmission is used to handle errors caused by impulse noise, buffer memory requirements may be reduced and/or data rate increased by detecting impulse noise at the transmitting equipment and initiating retransmission in response to such detection rather than waiting for a retransmission indication from the receiving end. The decision to retransmit may be made dependent on the strength or other properties of the detected noise burst. The decision criterion may be made adaptive by correlating noise burst properties with received retransmission indications or the absence thereof.
