摘要： It is presented a method performed in a first network node. The method comprises the steps of: receiving an uplink transmission from a mobile communication terminal; determining, based on content of the uplink transmission, information to be transmitted over a first communication channel when the content comprises control data intended for a second network node; transmitting the information over the first communication channel to the second network node when the information is to be transmitted over the first communication channel; and transmitting the information via a second communication channel, the second communication channel being physically separate from the first communication channel, when the information is not to be transmitted over the first communication channel. A corresponding network node is also presented.

摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analyzing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

摘要： A method for scheduling a first and a second channel in a subframe includes dividing transmission resources needed for the first channel into a first set of resource groups and assigning the resource groups of the first set to subelements in the subframe in a predetermined fashion. The method also includes assigning a symbol value to all subelements in the subframe which have not been assigned a resource group of the first set and dividing transmission resources needed for the second channel into a second set of resource groups. Additionally, the method includes assigning, in a predetermined fashion, the resource groups of the second set to subelements in the subframe by means of said symbol values.

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.

摘要： Method and apparatus in a communication unit employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received receive (RX) sub-frames, in transmit (TX) sub-frames available for transmission. An obtaining unit in the communication unit receives allocation parameters for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit in the communication unit then schedules feedback reports in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.
