A shared control channel structure includes at least one control channel to be allocated at least to a user for at least one of uplink and downlink directions in a network, which the at least one control channel is arranged as at least a part of a modular structure comprising of modular code blocks on at least two different sizes. One of such modular structures may be represented as a tree structure in particular, where each of the modular code blocks define one node of the tree, respectively.

Shared control channel structure

A method, user equipment, network device, and software product employ indicators from a plurality of respective cells to indicate a difference, if any, regarding allocation in the respective cell as compared to neighbor cells. Mobility measurements are then performed according to the indicators, and also on the basis of configuration of a cell where the measurements are performed.

Method, apparatus, and computer program product for signaling allocation of neighbor cells

In one non-limiting, exemplary embodiment, a method includes: receiving a message including a resource allocation map having a first portion and a second portion; utilizing the first portion to determine a specific mapping scheme of a plurality of mapping schemes, wherein the determined specific mapping scheme is used for the second portion; and obtaining, based on the determined specific mapping scheme, resource allocation information based on the second portion. In another non-limiting, exemplary embodiment, a method includes: generating a message including a resource allocation map having a first portion and a second portion, wherein the first portion is indicative of a specific mapping scheme of a plurality of mapping schemes that are applicable to the second portion; and transmitting the generated message.

Apparatus, methods, and computer program products providing a dynamic header structure for signaling resource allocations

Introducing a set of limitations on where different payload sizes are allowed in a control channel element aggregation 'tree' is shown. Following these limitations, the network element (e.g. Node B) will have a large flexibility for scheduling users, while the terminal (e.g. User Equipment) will have an option for still keeping the number of blind decoding attempts at a quite low number.

Signaling limitation of multiple payload sizes for resource assignments

A method of transmitting a transmit vector comprising symbols to be delivered within a resource unit from a transmitting station with one or more transmit antennas to one or more receiving stations with one or more receive antennas. The method comprises obtaining information on the state of channels between the one or more transmit antennas and the one or more receive antennas; and computing, on the basis of the channel states between the one or more transmit antennas and the one or more receive antennas, a covariance matrix R, a combined channel matrix H, and a block-diagonal linear operator V of decoding matrices of the receiving stations. The transmit vector is multiplied with a precoding matrix P fulfilling the equations()()=, i=1 . . . Ktrace()=and corresponding performing filtering in the receiving station using a receiver filter corresponding to the block-diagonal linear operator V.

Precoding method for transmitting information in a MIMO radio system

There is provided a base station comprising: an estimation unit for estimating a second or higher order statistics for each user terminal in a set of user terminals to be served; an estimation unit for estimating a scheduling metric based on the estimated second or higher order statistics; and a scheduling unit for controlling scheduling based on the estimated scheduling metric.
