WO/2016/064319 HANDLING HANDOVER OF AN UE IN CASE CELL SPECIFIC REFERENCE SIGNALS INTERFER WITH A PHYSICAL DOWNLINK CONTROL CHANNEL||WO||28.04.2016|
||PCT/SE2014/051337||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||JONSSON, Mikael |
A method performed by a network node 110, for handling handover of a user equipment (UE) 120, wherein the network node 110 serves a first cell 130 comprising one or more UEs 120. When the network node 110 has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE 120 in handover from the first cell 130 to a second cell 131, the network node 110 increases the number of OFDM-symbols included in a control region of a downlink OFDM-subframe sent in the first cell 130 in a Transmission Time Interval (TTI) related to the handover. By increasing the number of OFDM-symbols of the control region only during the handover, the physical downlink control channel (PDCCH) is spread in time into symbols not polluted by CRS symbols from neighboring cells. Thereby the number of unsuccessful handovers and lost service is effectively reduced.

WO/2016/064310 INCREASING ROBUSTNESS OF HANDOVER SIGNALLING BY INCREASING THE AGGREGATION LEVEL OF CONTROL CHANNEL ELEMENTS||WO||28.04.2016|
||PCT/SE2014/051239||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||SKÄRBY, Christian |
A method performed by a network node 110, for improving the performance of a handover of a user equipment (UE) 120, wherein the network node 110 serves a first cell 130 comprising one or more UEs 120. When the network node 110 has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE 120 in handover from the first cell 130 to a second cell 131, the network node 110 increases the Control Channel Element (CCE) aggregation level in an OFDM-subframe to be sent to the UE 120 in a TTI related to the handover. By increasing the CCE aggregation level during a handover procedure, the effective coding rate of the PDCCH is increased, which leads to a more robust coding and reliability. Thereby the number of unsuccessful handovers and lost service is effectively reduced.

||PCT/SE2014/051241||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||NOLAN, Julian Charles |
A device (100) for providing a touch-based user interface is disclosed. The device (100) comprises a screen (110), a camera (120), and processing means (101). The camera (120) is configured for imaging a reflection of the screen (110) by a cornea of a user of the device (100). The processing means (101) is operative to display at least one user-interface element (111, 112) on the screen (110), detect that a finger (151) of a hand (150) touches or is about to touch the screen (110), estimate a trajectory (261) of the finger (151), and determine an intended location of touch of the finger (151) on the screen (110). The trajectory (261) of the finger (151) is estimated by analyzing a sequence of images of the reflection. The intended location of touch is determined based on the estimated trajectory (261) of the finger (151). The described solution provides an improved touch-based user interface for hand-held devices (100), such as smartphones, tablets, or mobile terminals, by utilizing a top-down view of the user's finger (151), obtained by means of corneal imaging, as it interacts with the screen (110).
