Abstract: There are provided measures for multicarrier communication support, such as for non-adjacent multicarrier support for a contiguous-bandwidth receiver. Such measures exemplarily include receiving one or more carriers in a configurable contiguous bandwidth, calculating an imbalance metric representing a receiving imbalance over a set of carriers, said imbalance metric representing a difference between a first value based on received signal strength indication on each of one or more carriers and a second value based on received signal strength indication on each of one or more carriers, verifying, based on the calculated imbalance metric, whether a threshold condition relating to a current mode of an adjacent carrier mode and non-adjacent carrier mode is satisfied, and reporting an event for triggering reconfiguration of said configurable contiguous bandwidth to switch the current mode between said adjacent and non-adjacent carrier modes, if the threshold condition is satisfied.

Abstract: A user equipment UE sends to a network an indication that a neighbor cell is suitable for data communications with the UE. The UE is in a state with a serving cell in which no dedicated physical channel is allocated to the UE. In response to the indication the network and UE conduct multipoint communications between the UE and the serving cell and the neighbor cell using a common channel configuration the UE receives from at least one of the serving cell and the neighbor cell. In a UTRAN embodiment the state is a CELL-FACH state. Various embodiments details specific RRC messages for various signaling, and in one embodiment there are different procedures depending on whether the serving cell and the neighbor cell belong to the same or different NodeB groups. Further embodiments address when the neighbor cell is no longer suitable for multipoint data communications with the UE.

Abstract: A user equipment UE obtains channel configurations from each of a serving cell and n neighbor cells which have been determined to be suitable for data communications with the UE, from which the UE creates a combined channel configuration and utilizes it for multipoint communications with those cells. In specific embodiments: the respective channel configurations are obtained from the respective cells' system information; the n neighbor cells are determined to be suitable by the UE comparing each cell's received signal strength/quality against a threshold. The UE may get a neighbor cell list NCL and the threshold and consider each cell on the NCL as one of the n neighbor cells if its signal strength/quality exceed the threshold, then the UE may acquire system information for only those n neighbor cells instead of all cells on the NCL. The UE then reports in uplink signaling that the n neighbor cells are suitable.

Abstract: A method is provided for avoiding in-device interference. The method may include determining a portion of a frequency band used for data reception by a first wireless modem that may be affected by interference from a data transmission by a second wireless modem. The method may further include causing an indication of the determined portion of the frequency band to be provided to the first wireless modem. A corresponding apparatus and computer program product are also provided.

Abstract: A user equipment UE determines that a neighbor cell is higher priority than a serving cell, measures neighbor cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbor cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbor cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbor cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period Treselection.

Abstract: Aspects of the present invention include methods, apparatuses and systems that may be used for radio frequency and performance testing of communication equipment in a telecommunications network. According to one aspect of the invention, received data may be discarded during a test whenever a device being testing is unable to store the data, for example in a buffer. According to another aspect of the invention, the device being tested will provide data for transmission processing whenever there is an opportunity during the testing to transmit data, thus allowing the device to be aggressive in its data transmission.

Abstract: The present invention discloses a test method and a testing apparatus for type 3i receivers which use multicarrier operation in HSDPA. The method sequentially tests each carrier, one at a time. Applying multi-switches, channel emulators and efficient wirings, performance tests can be performed without any need for changing the User Equipment to be tested. In case a single carrier test is passed, the next carrier is selected for the test. All carriers are thus tested sequentially against a single carrier throughput requirement until all carriers have been processed.

Abstract: In accordance with an example embodiment of the present invention, a user equipment initiates autonomous cell reselection from a source cell to a target cell. Subsequent to the reselection, the user equipment transmits information relating to the source cell to the target cell. The network is in some embodiments configured to use the information for self-organizing network purposes by connecting source-target cell pairs as neighbours.
