    摘要: Data may be transmitted from a RAN node to a wireless terminal using a MIMO antenna array. A plurality of unmapped symbol blocks may be generated. Symbols of a first one of the plurality of unmapped symbol blocks may be mapped to first and second mapped symbol blocks so that the first mapped symbol block includes symbols of the first unmapped symbol block and so that the second mapped symbol block includes symbols of the first unmapped symbol block. The symbols of the first and second mapped symbol blocks may be precoded to provide precoded symbols of respective first and second MIMO precoding layers using a MIMO precoding vector. Each of the precoded symbols of the first and second MIMO precoding layers may be transmitted through the MIMO antenna array to the wireless terminal using a same TFRE. Related devices and terminals are also discussed.

    摘要: The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU-MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.

    摘要: A method for assisting the adaptation of a signal from a first node (100) to a second node (120) is provided. The first node communicates with the second node in a wireless communication system (110) over a radio link (130). The second node is configured to comprise a codebook, which codebook comprises a set of possible information alternatives used for assisting the adaptation of a signal from the first node to the second node. The second node may select an information alternative from a codebook and send it to the first node to assist the first node how to adapt the signal. The first node is arranged to know a number of subsets, each subset comprising a part of possible information alternatives. The method comprises the steps of sending a configuration request to the second node to restrict the selection of information alternatives to one of the subsets; receiving an information alternative from the second node, which is selected among the at least one subsets configured according to the configuration request.

    摘要: Methods and devices for managing a cellular communication system (1) and mobile terminals (40) are presented. A collective positioning measurement order (50) is issued to a multitude of mobile terminals (40) in a first cell (10) of the cellular communication system (1). This issuing is preferably performed intermittently at a multitude of times according to a predetermined rule. Each mobile terminal (40) receives information concerning a collective positioning measurement order. The mobile terminal (40) performs a positioning operation, typically a positioning measurement on a ranging signal (51 , 52) or transmission of a ranging signal (53). preferably intermittently at a multitude of times, according to a predetermined rule based on the information concerning the collective positioning measurement order. An updating of a storage with positioning data can preferably be obtained. In terrestrially based positioning systems, signal resources dedicated to positioning measurement can be reserved in the cellular communication system.

    摘要: A basic idea of the invention is to provide multi-user resource scheduling and distribution based on balancing the power resources used for the different narrow beams in order to smooth the interference levels over the whole cell, area and to reduce interference fluctuations. The resource scheduling principle according to the invention is especially useful when the available resources are not fully utilized. The idea is to select, for each antenna beam of at least a subset of the antenna beams, at least two mobile users for service using the respective antenna beam during a transmission time interval (Sl), and to distribute power resources to the antenna beams for use during the transmission time interval based on the guideline of balancing the power resources among different antenna (S2).

    摘要: An apparatus in a radio terminal (MS) determines a measure representing tranfer rate from a radio cell to the teminal. The apparatus includes units (SINR-1,…, SINR-4) for determining several signal quaility measures of pilot signals received from and associated with several antennas in the radio cell. A summation unit (SUM) combines several such signal quality measures into a conbined transfer rate measure associated with the radio cell. Such combined measures are determined for several radio cells surrounding the terminal. Further means (MEN, SEL, TH) select radio cells associated with combined transfer rate measures that support a predetermined tranfer rate as candidates for communication with the terminal. The selected measures are reported to the radio network controller and used for cell selection or handover.
