20130294415 | Dynamic Spectrum Refarming with Multiple Carriers - The present invention relates to dynamic spectrum refarming with multiple carriers. At a first communication system of a first radio access technology, a request is received in a first signaling message from a second communication system of a second radio access technology, the request including information on availability of spectrum blocks shared between the first and second communication systems. The availability of the spectrum blocks may have been determined based on a load of the second communication system. The first communication system performs carrier aggregation mechanisms based on the information with respect to the spectrum blocks, and may transmit a response to the request in a second signaling message to the second communication system, the response including an acknowledgment of an activation/deactivation of at least one additional carrier and/or a corresponding carrier aggregation. | 11-07-2013 |
20140200011 | LTE/HSDPA Carrier Aggregation - It is provided an apparatus, including deciding means adapted to decide, based on an availability indication received directly from a slave base station of a second radio access technology, if data to be transmitted to a user equipment are to be transmitted by the slave base station; distributing means adapted to distribute, based on the decision by the deciding means, the data to the slave base station for a transmission to the user equipment; transmitting means adapted to transmit the data to the user equipment according to a base station functionality of a first radio access technology if the data are not to be distributed to the slave base station. | 07-17-2014 |
20140293974 | Method of Transmission in a Communications Network - A method of transmission in a communications network is provided in which data is transmitted using a first radio access technology and a second radio access technology. The method includes providing an anchor carrier associated only with the first radio access technology and another carrier shared between the first radio access technology and the second radio access technology. Transmission via the second radio access technology is muted in the shared carrier during at least one subframe of each data frame transmitted using the second radio access technology. Data is transmitted using the first radio access technology in the shared carrier only during the at least one subframe in which transmission using the second radio access technology is muted. | 10-02-2014 |
20150016367 | Providing a Radio Bearer on a Plurality of Component Carriers - There is provided a radio bearer to user equipment on a first component carrier by a first network node and on a second component carrier via a second network node connecting to the first network node; and receiving data units of the radio bearer on the first component carrier on the basis of the first network node terminating a protocol bearer of the radio bearer. | 01-15-2015 |
20150029920 | Power Saving UL DTX and DL DRX Techniques for Multi-Flow Operation in HSPA - An apparatus includes multi-flow communicating means adapted to perform a communication with a UE including a portion of a multi-flow communication to the UE; evaluating means adapted to evaluate the communication with the UE; and providing means adapted to provide a DTX/DRX information based on the evaluation. The DTX/DRX information is related to at least one of a discontinuous transmission state and a discontinuous reception state of the UE. The instructing means is adapted to instruct the multi-flow communicating means to send DTX/DRX activation request with respect to the at least one of the discontinuous transmission state and the discontinuous reception state according to the DTX/DRX information to the UE. The storing means is adapted to store a status information, wherein the status information includes the at least one of the discontinuous transmission state and the discontinuous reception state corresponding to the instruction by the instructing means. | 01-29-2015 |
20150029998 | Inter-Node B Handover in HSDPA or Multi-Flow HSPA Including Packet Retransmission - The application relates to the removal of one of the links in multi-flow HSPA but the proposed method is also applicable to normal HSDPA operation during handover. In particular the application aims at minimizing the negative impact of a removed radio link, i.e. drop of packets and/or delays. According to the proposed method, in which the radio link to be removed is via a first Node B NB | 01-29-2015 |
20150071192 | Carrier Aggregation in Communications - A legacy base station receives, from a radio network controller, information on the amount of radio network resources that is available to be reserved for user terminals utilizing LTE-HSPA carrier aggregation. The legacy base station also receives a request directly via an interface from an LTE base station to perform a setup of a connection between the LTE base station and a user terminal by utilizing LTE-HSPA carrier aggregation. Based on the request, the legacy base station checks the received information in order to decide whether or not to grant the LTE base station a permission to set up the connection between the LTE base station and the user terminal by utilizing LTE-HSPA carrier aggregation. | 03-12-2015 |
20150085657 | Data Transmission Mechanism with Improved Robustness Using Multiflow Connection - There is provided a mechanism for conducting data transmission from a network management entity of communication network control element to a terminal or UE with improved robustness. After a multiflow connection for data units via at least one network transceiver device and via at least two different paths is set up towards a terminal, selection criteria are applied so as to decide which data units are sent on which transmission path. Specifically, dependent on the applied selection criteria, data units of specific data are selected to be subjected either to bicasting each selected data unit using the at least two paths, or to dynamic flow switching so as to transmit each selected data unit using one of the at least two paths and wherein each selected data unit can be in dependently chosen to be transmitted over either of the at least two paths. | 03-26-2015 |
