    摘要: A method and apparatus for accessing a wireless communication system, and for processing random access attempts. A mobile communication device detects random-access information transmitted by a base station, transmits a random-access preamble to the base station according to the random-access information, and receives a random-access response from the base station. The random-access response includes at least an allocation of uplink resources to be used for the next step in the random access procedure. The mobile device also selects a reference signal sequence index from a pre-determined set of sequence indexes, and transmits a first message to the base station using the uplink resource allocation provided in the random-access response. The first message includes a device identifier and a first demodulation reference signal derived from a base reference sequence shifted according to the selected sequence index.

    摘要: The present invention relates generally to methods and arrangements for positioning in a wireless communications system, such as LTE. In particular, the present invention relates to improving positioning accuracy. The invention provides methods and arrangements for scheduling positioning subframes, i.e. low interference subframes, for allowing aligning of positioning subframes across a number of cells in order to reduce the interference from data symbols of cells in the neighborhood of a cell serving the UE that is performing positioning measurements. A time instance during which transmission of the positioning subframes is to occur in a wireless communications network is selected. The base stations in the wireless communications network are informed about the selected time instance, whereupon the base stations schedule and transmit the positioning subframes based on the selected time instance, whereby the positioning subframes are aligned throughout the network.

Each CIF-value is mapped to a respective component carrier comprising a respective shared data channel. Each respective shared data channel corresponds to at least one downlink control channel carrying said each CIF-value. The radio network node reconfigures mappings from CIF-values to component carriers, while at least one mapping of CIF-value to component carrier is maintained. The component carrier of said at least one mapping from CIF-value to component carrier comprises said at least one downlink control channel and a shared data channel corresponding to said at least one downlink control channel. The radio network node sends at least one of the reconfigured mappings from CIF-values to component carriers to the user equipment.

    摘要: Systems and methods for providing bandwidth adaptive reference signals are disclosed. In one embodiment, a wireless device receives a downlink signal from a base station in a cellular communication network on a corresponding downlink carrier, where a number of time domain units per frame in the downlink signal that carry reference symbols is determined based on, or is otherwise a function of, a system bandwidth of the downlink carrier. In addition, in some embodiments, a number of frequency domain units that carry reference symbols is also a function of the system bandwidth of the downlink carrier. The wireless device processes the reference symbols to provide one or more desired features such as, for example, synchronization, radio resource management measurements, channel estimation, or the like.
