20090052431 | METHOD AND DEVICE FOR PACKET BASED CLOCK RECOVERY - A master clock in a first radio network unit, configured for sending data packets at predetermined time intervals, is synchronized with a slave clock in a second radio network unit. To provide a method for packet based clock recovery being able to achieve the desired accuracy within an acceptable time while avoiding a high computational complexity, the following procedure is used. An estimate value is determined for the transmission delay time for each data packet in a predetermined set of data packets. At least one pair of data packets is selected that has a minimum estimate value for the transmission delay time. A difference of the reception times of the selected pair of data packets is determined. Finally, a clock estimate procedure is performed using the difference of the reception times of the selected pair of data packets to determine the quantity representative of the clock frequency difference and/or the clock time offset. | 02-26-2009 |
20120063413 | Communication Resource Allocation Strategy - A scheduling processor allocates a time slot of a communication protocol to a user equipment for data transmission based on received control data of the same or another user equipment in a current time slot and received user data of the same or another user equipment in a preceding time slot, while ignoring user data of the same or any other user equipment received in the current time slot. The scheduling processor also allocates a frequency resource to the user equipment. A control channel managing processor allocates signaling resources on a control channel for the submission of control information to the user equipment, which informs of the time slot allocated by the time domain scheduling processor as well as of the frequency resource allocated by the frequency domain scheduling processor. | 03-15-2012 |

20140293952 | Scheduling a Transmission of Data - Transmission of data is scheduled via a first communication channel within a first cell of a cellular network. A first base station is assigned to the first cell. A user equipment is served by the first base station, and the first communication channel is divided into subframes. The cellular network includes a second base station assigned to a second cell, wherein the second base station uses a second communication channel divided into subframes, and a part of the subframes is unscheduled by the second base station due to a predefined muting pattern. The first base station determines a first subframes of the first communication channel related in time with the unscheduled subframes of the second communication channel, and schedules transmission of data between the first base station and the user equipment via the first communication channel so that the data is transmitted in the determined first subframes. | 10-02-2014 |
20140328316 | Rate Capping with Multiple Carrier Aggregation Schedulers - Requests for carrier aggregation scheduling for a user equipment are received from a first cell used for carrier aggregation and n second cells. The requests include a first scheduling decision of the first cell and n second scheduling decisions of the n second cells. It is checked whether or not the requests exceed limits of the user equipment, and the n second scheduling decisions are modified according to predefined rules such that the requests do not exceed the limits. Limits of the user equipment are increased by a margin, the increased limits are split onto active cells of the first and n second cells according to a predefined rule, and the margin is controlled dependent on whether the increased and split limits are exceeded or not by the requests. If they are exceeded, the n second scheduling decisions may be modified. | 11-06-2014 |
20150050935 | Controlling a Radio Resource Control Connection Between a Base Station and a User Equipment - It is described a method for controlling a radio resource control connection between a base station and a user equipment, wherein a radio resource control connection between the base station and the user equipment is established for exchanging control messages between the base station and the user equipment the control messages being required for an application running on the user equipment. The method includes determining a first value being indicative for a mobility characteristic of the user equipment and a second value being indicative for a data traffic characteristic of the user equipment, comparing the first value and the second value, setting a release timer based on the comparison, and controlling the radio resource control connection based on the release timer, wherein the radio resource control connection will end upon expiry of the release timer. | 02-19-2015 |
