    摘要： Method and controlling network node (140) for transmitting data to a user equipment (130) over a set of radio links (115,125), when a radio link (115,125) is added, or removed. The controlling network node (140) is configured to communicate data to the respective radio network node (110,120) over a respective backhaul link (118,128), of which at least one backhaul link (118) is connected over an Internet Protocol, IP, network (150). The method (500) comprises measuring (501) the time delay over the corresponding backhaul link (118,128) for each radio link (115,125), determining (502) time difference between them, calculating (503) a buffer time for each radio link (115,125), and buffering (507) data in a buffer (625) for the calculated period of time before forwarding the data to the radio network node (110,120), for transmission to the user equipment (130).

    摘要： The invention discloses a mobile-unit-assisted modulation scheme management, in which a mobile unit (100) performs signal quality measurements on a communications link (410), over which data modulated with a first modulation scheme is communicated. The mobile unit (100) determines a first link quality measure for this first modulation. Furthermore, the mobile unit (100) estimates second quality measure(s) for currently non-employed modulation scheme(s) based on this first quality measure. Selection information is then generated based on this first quality measure and the second quality estimate(s). This quality measure estimation is performed based on the capabilities and the particular modulation scheme versions of the mobile unit (100).

    摘要： The present invention relates to a method and an arrangement in a first communication node (115) for adjusting a channel quality report transmitted between the first communication node (1 15) and a second communication node (105). The first communication node (115) and the second communication node (105) are comprised in a wireless communication network (100), and are adapted to communicate with each other via a radio link (1 10). In a first step, a channel quality report is received (600) from the second communication node (105). The channel quality report is established by the second communication node (105). Then at least one channel characteristic parameter is obtained (601 ). The next step is to determine a channel quality offset based on the obtained channel characteristic parameter. Based on the channel quality offset, the channel quality report is adjusted (605).

    摘要： In a radio communication system that includes multiple service areas, each service area is associated with a predetermined number or amount of radio communication resources. Each radio communication resource can be used for a prescribed period of time corresponding to one or more time units. An operator or other entity identifies a set of service areas to be tested at an increased effective load. A desired test level (e.g., increased traffic load) is determined, and a corresponding number of radio resource time units is determined to achieve the desired test level conditions. Use of radio communication resources in the determined one or more time units is blocked for a test period. Performance by each service area during the test period is determined.

    摘要： A method and apparatus for determining the content in bursts (312) to be transmitted from a base station (300a) in a mobile network on a broadcast frequency (314) in specific timeslots of a broadcast frequency frame structure. A current state of the logical channel allocated to the forthcoming burst is checked (502), and the content in the forthcoming burst is determined depending on the current channel state. A dummy burst with a base station specific training sequence is transmitted if there is no data to transmit, and if the dummy burst cannot be confused with a regular traffic burst according to the current channel state. The dummy burst contains no intelligible information to mobile terminals.
