20110149813 | FLEXIBLE SUBFRAMES - The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame. | 06-23-2011 |
20110216710 | Method and Apparatus for Controlling Access to a Radio Resource - In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, in one embodiment distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. When a user, in particular a primary user, is detected by a node, a spectrum access blocking message is sent, to other nodes in the vicinity of the node thereby enabling blocking of the radio resource in a geographical area in which the other usage is detected. This means that the radio resource is blocked in that area from being accessed by other users than the primary user. The blocking message can be distributed in any suitable manner and can be tailored for the application at hand. | 09-08-2011 |
20110217922 | METHOD OF SENSING IN A RADIO SYSTEM EMPLOYING OPPORTUNISTIC SPECTRUM ACCESS - In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. The wireless nodes are configured to perform sensing of at least one radio resource. A node can be adapted to combine the sensing measurement data into a sensing result, such as an estimate of the probability of whether the resource is free or not. The sensing performed in a node is distributed to at least one other wireless node. Each wireless node can, therefore, access sensing information from at least one other wireless node located in the vicinity of the wireless node. Based on the collective information from at least one other node, a wireless node can make an improved decision if a particular radio resource is free to use or not. | 09-08-2011 |

The wireless nodes are adapted to perform sensing of at least one radio resource in response to a request from a node. Based on the collective information from at least one other wireless nodes a wireless node can make an improved decision if a particular radio resource is free to use or not. | 09-22-2011 |

20120064902 | Method and apparatus for transmitting available radio access possibilities in a communications area - The technology described in this application provides a wide-area radio access information transmission scheme where the wide-area radio access information transmitter shares its radio resources with local radio access information transmitters. The radio resources may be divided for example in one or more of the time, frequency, space, and/or code domains. The wide-area radio access information transmitter sets aside and does not use some portions or “chunks” of its radio resources and allocates those unused portions or chunks for use by local radio access information transmitters to transmit local radio access information signals. In one non-limiting example embodiment, the radio resources include time slots, and during those time slots allocated to the local radio access information transmitters, the wide-area radio access information transmitter does not transmit, and thus, is quiet. Hence, those allocated time slots are referred to as “quiet periods” from the perspective of the wide-area radio access information transmitter. The wide-area radio access information transmitter can optionally explicitly signal what those resources are to simplify for the local radio access information transmitters who otherwise have to detect those resources themselves. | 03-15-2012 |
20120064930 | METHOD AND APPARATUS FOR TRANSMITTING AVAILABLE RADIO ACCESS POSSIBILITIES IN A COMMUNICATIONS AREA - A local radio access information transmitter for use in a communications area serviced by multiple different radio access technologies (RATs) allocated to different radio resources in different locations in the communications area. Each RAT is associated with one or more RAT radio transceivers for serving user equipments (UEs) at least in some portion of the communications area using one of the multiple RATs. The local radio access information transmitter is in addition to the RAT radio transceivers and located near an associated hotspot service area at least partly inside the communications area. The local radio access information transmitter determines local radio access information including one or more different RATs available for UE service in the hotspot service area and a frequency of frequencies of operation allocated to each RAT in the hotspot service area, sends a registration message to a wide area radio access information controller, and based on a response from the wide area radio access information controller, determines what radio resources to use to transmit the local radio access information signals. Radio transmission circuitry transmits the local radio access information signals for receipt by UEs in the hotspot service area using the determined radio resources. | 03-15-2012 |
