摘要： In one embodiment, a method of operating a radio access node is provided. The method comprises determining whether support from a secondary cell is required for a wireless device to communicate with the radio access node, and, in response to determining that support from the secondary cell is required, calculating a modified channel condition outer-loop value for the secondary cell; and using the modified channel condition outer-loop value in an initial activation decision step for the secondary cell. The initial activation decision step may comprise activating the secondary cell in response to determining that the sum of a device reported channel condition value and the modified channel condition outer-loop value is above an activation threshold. Corresponding devices, computer programs and radio access nodes adapted to carry out the methods provided are also disclosed.

摘要： A method for link adaptation is provided. Data associated with a user device is stored. A first number of scheduling blocks, SBs, required to transmit the stored data is estimated based at least in part on a first modulation and coding scheme (MCS). The first MCS corresponds to a first channel performance level. A second MCS is determined based at least in part on a link quality. The second MCS corresponds to a second channel performance level. A determination is made whether second channel performance level is less than the first channel performance level. An operating MCS is selected based at least in part on whether second channel performance level is less than the first channel performance level. The data is scheduled for transmission based at least in part on the selected operating MCS.

摘要： A system and method for adaptively managing frame size in a wireless multihop network (100) is disclosed. In one embodiment, a packet is transmitted from a source to a destination (420). A acknowledgement packet (422) is received and a successful acknowledgement packet counter is incremented if the acknowledgement packet arrives prior to a time-out of a timer (444). A frame size is increased if the successful acknowledgement packet counter reaches a specified value (446, 448). If the acknowledgement packet arrives after the time-out of the timer, the successful acknowledgement packet counter (460) is reset and the frame size (462) is decreased. These procedures can be repeated until the frame size is greater than or equal to a maximum frame size (450) or less than or equal to a minimum frame size (464).
