In accordance with an example embodiment of the present invention, an apparatus, comprising at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: deciding to switch to a half-duplex mode of operations upon detecting a triggering condition including that multiple radio stacks are activated at the apparatus simultaneously; signaling an associated base station the decision of switching to the half-duplex mode half-duplex mode; and entering the half-duplex mode of operation, is disclosed.

Method and apparatus for avoiding interference between multiple radios in a user equipment

In a first aspect an exemplary embodiment of the invention provides a method that includes instantiating a plurality of radio protocols, operating the plurality of radio protocols with an underlying physical layer, where each instantiation of a same radio protocol is embodied in a same code module and where each instantiation has associated data stored in a memory. The operating of the plurality of radio protocols comprises executing each instantiation of the radio protocols so that a portion of resources are shared between different instantiations of the radio protocols and different instantiations of radio protocols do not interfere with each other.

Multiple radio instances using software defined radio

An apparatus for controlling at least one radio module, wherein the apparatus is configured to generate at least one service request for a first radio mode, determine at least one logical architecture model dependent on each service request, select at least one of the plurality of radio modules to form a physical architecture structure dependent on each logical architecture model, and generate at least one configuration data set dependent on the selected one of the plurality of radio modules.

Radio frequency apparatus

Embodiments of the invention enable fast context switching of application specific processors having functional units with an architecturally visible state. In example embodiments, a processor allocates memory space to store two process control blocks for two active tasks to be performed by the processor comprising one or more custom functional units having a respective processing state not accessible by the processor. A memory controller stores the processing state of the custom functional units currently running a first active task, in a first process control block, in response to a preemptive task switch requirement. The memory controller loads a second processing state of the custom functional units for a second active task, from a second process control block in the memory, in response to the preemptive task switch requirement. The processor may then perform the second active task, based on the second processing state loaded into the custom functional units.

Method, apparatus, and computer program product for fast context switching of application specific processors

Method, apparatus, and computer program product embodiments of the invention are disclosed for efficient communication between processor units in a multi-core processor integrated circuit architecture. In example embodiments of the invention, a method comprises: storing with a shared inter-core communication unit in a multi-core processor, first data produced by a producer processor core, in a first token memory located at a first memory address of a memory address space; and connecting with the shared inter-core communication unit, the first token memory to a consumer processor core of the multi-core processor, to load the first data from the first token memory into the consumer processor core, in response to a first-type command from the producer processor core.

Method, apparatus, and computer program product for inter-core communication in multi-core processors

A system for making resources in an apparatus available to an entity outside of the apparatus. In at least one example operational scenario, an apparatus may wirelessly interact with other apparatuses via various communication protocols. These apparatuses may be part of an architecture that allows resources to be shared within the architecture. An 'entity' may further exist in the architecture that controls how resources are borrowed from, or how resources are provided to, the individual participating apparatuses. Access to apparatus resources may be provided through reallocation of reconfigurable components to a control element within the apparatus, the control element corresponding to the entity existing outside of the apparatus.

Wireless resource sharing framework

In a non-limiting and exemplary embodiment, a method is provided arranging control of multiple radio systems of a wireless communications device. A second scheduler performs proactive scheduling decisions on the basis of radio resource usage requirements of radio systems of the wireless communications terminal device and sending information on the proactive scheduling decision to a first scheduler. The first scheduler performs reactive scheduling decisions on the basis of the proactive scheduling decision information from the second scheduler.

Multiradio control

In a non-limiting and exemplary embodiment, a method is provided for controlling co-existence of multiple radio access units. The method comprises: receiving a scheduling request comprising value information on at least some of radio independent scheduling parameters of a control interface common to a plurality of radio access units, scheduling radio access on the basis of the value information on at least some of the radio independent scheduling parameters, and sending a response to the scheduling request in a given form in accordance with the control interface common to the radio access units.
