Abstract:
The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access 5 ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL-FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.
Abstract:
The present invention relates to methods and arrangements for scheduling of positioning channels and traffic in order to recover a sufficiently perfect orthogonality including scheduling tasks for the downlink and uplink direction. A scheduling manager co-ordinates the scheduling and measurement timing of first and second positioning schedulers that, respectively, allocate uplink and downlink radio resources.
Abstract:
The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared byuser terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.
Abstract:
The embodiments of the present invention relates to a method in a UE for distributing available transmit power to avoid violation of UE power limitations on the PUCCH and the PUSCH. Available power for transmission on at least the PUCCH is determined and at least one power headroom report indicating the available power for transmission on at least the PUCCH is transmitted to a base station.
Abstract:
The present invention relates to methods and arrangements for interference reduction for bursty or intermitted transmissions. DPCCH gating with regular on/off-gating patterns can create waveforms that can interfere with non-UMTS audio equipments, e.g. hearing aids. The present invention relates to modifying the transmission instants of data packets in such a way such interference can be significantly reduced. This is achieved by introducing a randomization mechanism into the mapping function of data packets onto the HARQ processes, which in turn are mapped onto predefined transmission occasions (sub-frames). This results in a non-periodic transmission pattern while maintaining user data transmission requirements.
Abstract:
A terminal (e.g., mobile communication device, UE) and a method are desert bed herein for allocating a soft buffer after interacting with a network node (e.g., base station, eNB). In addition, a network' node (e.g., base station, eNB) and a method are described herein that facilitates robust operations during a reconfiguration period while a terminal allocates a soft buffer located therein.
Abstract:
The auto-correlation properties of a reference signal or pilot pattern, such as a position reference signal (PRS) in a Long Term Evolution communication system, is improved by modifying the currently specified PRS patterns, and/or by PRS pattern shaping. Pattern shaping can result in creation of virtual PRS patterns, for example, by 5 controlling the PRS transmitted or received power used by the correlator. PRS power shaping can be implemented differently according to the location where the PRS power is calculated, e.g., in a network node or in a user equipment.
