An apparatus and a method is provided, by which a first type cell is controlled, wherein a plurality of second type cells are located in the same area as the first type cell, wherein control signal transmission to at least one user equipment is carried out via the first type cell and data transmission to the at least one user equipment is carried out via one of a plurality of the second type cells, and handover of data transmission of a user equipment from a source cell being one of the plurality of second type cells to a target cell being another one of the plurality of second type cells is controlled. Moreover, also an apparatus and a method of e.g., a user equipment are provided, by which a handover of data transmission from a source cell being one of the plurality of second type cells to a target cell being another one of the plurality of second type cells is performed, while maintaining control signal transmission with the first type cell.
摘要:
Systems and techniques for link condition reporting in multiple connection systems. A base station, such as a macro eNodeB (eNB) configures measurement objects and reporting objects for macro and local area links for a user device such as a user equipment (UE). The objects relating to the secondary links are configured for use when the user device is operating in a dual connection mode. Upon detection of a triggering event when the user device is in dual connection mode, the user device reports macro and secondary link information. In some embodiments of the invention, triggering may be based on events related to a specified frequency group, or may be direct measurements related to a specified frequency group.

Apparatus, methods, and computer programs that selectively transmit one or more local area buffer status reports by a macro base station over a macro link or transmit a macro buffer status report by a local area access point over a local area link in a dual connection deployment scenario in response to a cross link buffer status report trigger. The apparatus, methods and computer programs may include several cross buffer status reporting triggers. The user equipment may trigger cross buffer status reporting in response or incidental to one or more measurement events. The user equipment may also trigger cross buffer status reporting in response to or incidental to a link failure. The user equipment may also trigger cross buffer status reporting in response to receiving a request from an eNB.

The present invention relates to methods, apparatuses and a computer program product for carrier allocation. The invention includes defining change occasion for a base station for changing a component carrier. The invention further includes receiving, at a processor, from a first base station, information regarding carrier interference severeness between the first base station and a second base station, wherein the carrier interference severeness comprises at least one of an expected separately usable protected carrier number, the number of user equipments located in a common coverage area of the first and second base station, and the downlink traffic load related to the user equipments, and allocating carrier pattern for the first base station based on the received information. Further, the invention includes composing, by a part of a first base station, a report including information regarding carrier interference severeness between the first base station and a second base station, wherein the carrier interference severeness comprises at least one of an expected separately usable protected carrier number, the number of user equipments located in a common coverage area of the first and second base station, and the downlink traffic load related to the user equipment, and causing transmission of the report to an allocating unit.

The present invention addresses a method, apparatus and computer program product for enabling enhanced repetition transmission for downlink control signal to improve machine type communication coverage. One or a plurality of downlink control channel signaling window lengths is/are predefined, a start position of a window in which repetition of download control signal is allowed is determined based on the determined control channel signaling window length for each window length, and transmission of repetition of download control signal is caused at the determined start position in the respective obtained window length.

During discontinue reception (DRX) operation of a mobile terminal of a wireless communications network, methods to ensure that user equipment is in an awake mode when a network node sends a scheduling grant on the physical downlink control channel (PDCCH). Dynamic scheduling (DS) and semi-persistent scheduling (SPS) grants may appear on PDCCH only once. One method defines every received downlink (DL) semi-persistent scheduling (SPS) signal in a subframe as active time in a configured DRX cycle and includes in said defining active time any occurrence of a DL assignment being configured for the subframe. A second method receives an indication of a downlink transmission or a configured downlink assignment configured for the current PDCCH subframe, starts a Hybrid Automatic Repeat request (HARQ) Round Trip Timer (RTT) whether UE is in active time or not, and stops a drx-RetransmissionTimer for the corresponding HARQ process whether UE is in active time or not.

A method, apparatus and computer program product are provided in order to enhance network notification of secondary cell activation. In a first embodiment, the method includes receiving a secondary cell activation command, activating a secondary cell, and transmitting a PHR indicating activation of the secondary cell. In a second embodiment, the method includes receiving a secondary cell activation command, activating a secondary cell, and transmitting a signal indicating an expected time period until activation of the secondary cell. In a third embodiment, the method may optimize implicit SCell deactivation by receiving a secondary cell activation command, activating a secondary cell, receiving a PDCCH order for an uplink grant or a downlink assignment, and starting a secondary cell deactivation timer associated with the secondary cell in response to receiving the PDCCH order. A corresponding apparatus and computer program product are also provided.
