Abstract: An arousal level control apparatus calculates a setting value of a control device under a constraint condition using an arousal level optimization model so that a value of an objective function is maximized. The control device affects a physical quantity of a surrounding environment that affects arousal level of a subject. The arousal level optimization model includes the constraint condition and the objective function. The constraint condition includes a physical quantity prediction model, an arousal level prediction model, and a setting value range condition that the setting value is within a predetermined range. The physical quantity prediction model is an explicit function that includes the physical quantity and the setting value as explanatory variables and has a predicted value of the physical quantity as an explained variable.

Abstract: A RAN node (2) receives a message containing a Non-Access Stratum (NAS) security parameter from a radio terminal (1), during a procedure in which the radio terminal (1) requests the RAN node to broadcast on-demand system information. The RAN node (2) sends an authentication request message containing the NAS security parameter to a core network node (3), in order to request authentication of the radio terminal (1). The RAN node (2) broadcasts the on-demand system information in response to receiving from the core network node (3) an authentication response message indicating successful authentication of the radio terminal (1). This can contribute to, for example, preventing on-demand SI from being broadcast in response to a request from a malicious radio terminal.

Abstract: A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N?a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N?a), which are not currently allocated, is allocated.

Abstract: Methods and apparatus for implementing a spectrum access controller (SAC) which protects a protected entity from excessive interference are described. A spectrum access controller (SAC) divides the coverage contour of the entity to be protected into geospatial zones called protection zones. Each protection zone is protected against interference from a neighboring area called an interference neighborhood. Each interference neighborhood is divided into interference zones based on their interference potential or distance from the protection zone. Potential interferers are grouped based on their location in the interference zones or interference potential. The interference quota for the protection zone is divided among the potential interferers in each group/zone. The quota may be divided unequally among groups/zones, e.g., based on their overall interference potential or proximity to the protection zone, or number of interferers.
