摘要： A method for use in a wireless communications system in which there is at least a first mode which controls the traffic to and from user terminals in a cell within the system, so that there is downlink traffic in the system. The first node transmits downlink traffic in radio frames, each of which comprises sub-frames. The first node performs measurements on pre-defined system indicators in at least said first cell, and based on the results of said measurements, the first node is allowed to autonomously decide to vary the number of available down link sub-frames used for down link traffic in said down link radio frames and also to vary the content of the down link sub frames which are used, said decision being valid for a time which is specified by the first node.

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 (400) 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 RX sub-frames, in TX sub-frames available for transmission. An obtaining unit (402) in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit (404) in the communication unit then schedules feedback reports (FR) 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.

摘要： A method (500) for use in a user terminal (120, 130) in a cellular communications system (100). According to the method, the user terminal applies a first timing advance value (505) to its transmissions to a controlling node (140), and the user terminal (120, 130) requests communication with the controlling node (140) in a contention based procedure by transmitting an access request (MSG 1), in response (515) to which the controlling node transmits an initiation message (MSG 2) along with (520) a second timing advance value. According to the method (500), the user terminal (120, 130) uses (530) the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

摘要： A method in a base station for controlling a Random Access, RA, procedure is provided. The base station initiates (201) an RA procedure on a Secondary Cell, SCell, in a User Equipment, UE, by sending to the UE a Physical Downlink Control Channel, PDCCH, order for a RA procedure on the SCell. At initiation of RA, the base station starts (202) a timer in the base station. The timer is a timer for random access failure detection associated with said initiated RA procedure. If the RA procedure has not been completed before expiry of said timer, the base station sends (205) a command to the UE, commanding the UE to deactivate the SCell, and thereby stopping the RA procedure on the SCell.

摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.
