摘要： An estimate of a cost of allocating radio resources available for allocation to the at least one radio link within a cell is generated in dependency 5 of which radio resources have been used within the cell at previous times. This cost estimate can be compared to a quality gain of allocating the radio resources to the radio link, and an allocation decision can be made in dependency of the comparison result.

摘要： A method for managing uplink channel estimation in a base station includes transmitting downlink data from a base station to a mobile terminal in a radio access network over a first portion of a Frequency Division Duplex (FDD) spectrum. The first portion of the FDD spectrum is designated for downlink data transfer. The method also includes transmitting a predetermined reference signal from the base station to the mobile terminal over a second portion of the FDD spectrum. The second portion of the FDD spectrum is designated for uplink data transfer. The predetermined reference signal permits the mobile terminal to perform a channel estimate on at least a portion of the second portion of the FDD spectrum. The method additionally includes receiving uplink data transmitted from the mobile terminal to the base station over the second portion of the FDD spectrum.

摘要： The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier.

摘要： Variable bandwidth assignment and frequency hopping are employed to make efficient use of radio resources. Variable bandwidth assignment is achieved by dynamically allocating different numbers of subcarriers to different mobile terminals depending on their instantaneous channel conditions. The frequency hopping patterns are determined “on-the-fly” based on the current bandwidth assignments. The bandwidth assignments and frequency hopping patterns are signaled to the mobile terminals in a scheduling grant.

摘要： The present invention relates to frequency hopping in wireless communication systems utilizing single-carriers with varying bandwidth. Frequency hopping is made possible by dividing the available bandwidth, associated to the available frequency spectrum, in a levelled structure, a bandwidth tree. By the use of a frequency hopping tree, which has the same structure as the bandwidth tree and wherein each leaf represent a hopping sequence, a frequency hopping scheme is determined. Orthogonality in-between the frequency hopping schemes for different users is ensured by letting a users hopping sequence value at a level n, be dependent on the hopping sequence value associated to the same branch structure on the adjacent level closer to the root of the tree, n−1, and an input sequence associated with the level n.

摘要： According to methods and apparatus taught herein, user equipments (UEs) in a wireless communication network are scheduled based on determining received signal power densities for a plurality of UEs to be scheduled, allocating UEs to scheduling intervals based on a sorting of their received signal power densities, and assigning UEs in the same scheduling interval to mirror frequency bands within an available frequency spectrum according to the sorting. For example, UEs to be scheduled are assigned to a given scheduling interval in rank order of their received signal power densities until the scheduling interval is fully allocated. Remaining UEs are assigned in rank order to one or more other scheduling intervals, and the process may be repeated or otherwise carried out on an ongoing basis. Such an allocation scheme tends to minimize both adjacent frequency and mirror frequency interferences between UEs scheduled in the same interval.
