20130029706 | Spectrum Sharing and Management of Cognitive Transmission - A wireless spectrum is shared between a primary communication system and secondar communication system operating in an overlapping geographical region. A primary transmitter broadcasts a primary signal, and a secondary transmitter transmits a secondary signal, both using a primary wireless spectrum assigned to the primary communication system. The secondary transmitter transmits the secondary signal to a secondary receiver with power (1-a)P and transmits the primary signal with power αP. The parameter α is computed to ensure a predetermined quality of reception of the primary signal by a hypothetical primary receiver located near the secondary transmitter. The secondary transmitter may compute a feasibility of using cognitive transmission and, when the computed feasibility exceeds or docs not exceed a feasibility threshold, it selects to enable or disable, respectively, the use of the primary wireless spectrum to transmit from the secondary transmitter. | 01-31-2013 |
20130035064 | Methods Of Modifying Communication Network Access And Related Network Nodes, And Wireless Terminals - A method may be provided in a wireless terminal to modify access to a Radio Access Network. The method may include providing a barring rate at the wireless terminal and providing a barring rate modifier at the wireless terminal. A modified barring rate may be provided at the wireless terminal responsive to the barring rate and the barring rate modifier with the modified barring rate and the barring rate being different. A random number may be provided at the wireless terminal responsive to attempting to access the Radio Access Network, and access of the wireless terminal to the Radio Access Network may be blocked responsive to the random number failing to satisfy a threshold of the modified barring rate. Related wireless terminals, network nodes, and network operations are also discussed. | 02-07-2013 |
20150103766 | Technique for Data-Over-NAS Signalling - A technique for signalling activation or deactivation of a data-over-non-access-stratum, NAS, transmission scheme is disclosed, the transmission scheme being for transmitting data packets over the NAS between a terminal and a base station, and being started in an idle mode. In a method aspect, there are steps of determining a trigger condition indicating a need for the data-over-NAS transmission scheme, and signalling an indication for activation or deactivation in response to fulfilment or non-fulfilment of the determined trigger condition. In another method aspect, there may be steps of receiving the indication for activation or deactivation, and activating or deactivating the data-over-NAS transmission scheme in response to the signalled indication. | 04-16-2015 |
