A device may detect a service condition associated with a network. The device may determine a prioritization of cells of the network based on characteristics of one or more subscribers to the cells of the network. The characteristics may include at least one of: a service type characteristic, an application type characteristic, a mobility characteristic, a vector characteristic, an altitude characteristic, a position characteristic, a location type characteristic, a device type characteristic, a device capability characteristic, a connection characteristic, a subscription characteristic, a call type characteristic, a user profile characteristic, a terrain characteristic, or an operator relationship characteristic. The device may perform an alteration to one or more network parameters based on the prioritization of cells of the network to reduce an impact of the service condition.

A new radio base station establishes a first and a second component. The first and second component carrier overlap each other. The base station transmits first synchronization signal blocks on the first component carrier. The base station transmits second synchronization signal blocks on the second component carrier interleaved in time with the first synchronization signal blocks.

A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. At least one of the second radio station (2) and the radio terminal (3) is configured to transmit, to the first radio station (10), information about a problem occurring in a radio link in the second cell (20) between the second radio station (20) and the radio terminal (30) while the carrier aggregation of the first cell (10) and the second cell (20) is being performed.

A sensor arrangement method is provided. The method includes, in response to an event to additionally arrange a first sensor in a preset service area occurring, identifying sensing coverage and network coverage of a second sensor based on position information, state information, and network information of a pre-arranged at least one second sensor, and determining an arrangement position of the first sensor based on sensing coverage and network coverage of the second sensor, and sensing coverage and network coverage of the first sensor.

Certain aspects are directed to a base station router disposed in a distributed antenna system. The base station router includes a backplane and a controller. The backplane can manage an availability of sectors for coverage zones. Each sector can include communication channels to be radiated to mobile devices in the coverage zones and can represent an amount of telecommunication capacity. The controller can respond to a traffic indicator by causing the backplane to redistribute the availability of at least one sector. The sector can be redistributed from a first coverage zone to a second coverage zone.

Methods and systems for communicating in a multi-carrier communication system are disclosed. Radio resources may be organized in at least three hierarchical levels. The hierarchical levels may comprise macroblocks, blocks, and radio resource elements. A macroblock may contain a plurality of blocks and a block may contain a plurality of radio resource elements. The radio resource elements may further correspond to subcarriers in an orthogonal frequency division multiplexing (OFDM) symbol. An index in a control message may specify a modulation and/or coding scheme (MCS) pattern indicting a MCS for each block within a macroblock. In an embodiment, fewer bits are used by the index to specify a MCS pattern that is used statistically more frequently, and more bits are used by the index to specify a MCS pattern that is used statistically less frequently. Signals may be transmitted over the plurality of macroblocks.

Embodiments are provided for a multi-objective scheme for solving a cell switch-off problem. The multi-objective solution seeks to minimize or reduce network energy consumption by switching off some of the cells in the network while allowing enough capacity according to traffic needs and quality of service requirement. An embodiment method includes determining, for each one of a plurality of established traffic profiles, a set of solutions with respect to a number of active cells from a plurality of cells in the network and an aggregate network capacity. The method further includes matching a given traffic profile to one of the established traffic profiles, and evaluating performances of the solutions corresponding to that traffic profile. A solution from the solutions is then selected in accordance with the evaluation. The selected solution indicates which of the cells in the wireless network to be switched off.
