    摘要： According to some embodiments, there is provided a base station system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL value, which can lead to the UE lowering its output power.

    摘要： A high-power point (110) and one or more low-power points (120) transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).

    摘要： The invention relates to methods and arrangements in a transmitting node for enabling a receiving node to perform measurements on interference caused by transmissions from at least one transmission point controlled by the transmitting node on receptions at the receiving node. The transmitting and receiving nodes are comprised in a wireless communications system. The transmitting node determines an interference measurement resource, IMR, for the receiving node. The receiving node is expected to measure interference on the IMR. The transmitting node then transmits at least one interfering signal on the IMR. The at least one interfering signal is not expected to be decoded or coherently measured upon by any node served by the transmitting node.

    摘要： Techniques are disclosed for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions. In one example method, a signal includes B bits for identifying a reference signal is received, wherein each of several available reference signals is defined by a cyclic shift and an orthogonal cover code. The B bits are used to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

    摘要： Disclosed are methods and apparatuses in user equipments (1400) and network nodes (1410, 420) for controlling transmission power of the user equipments when the user equipments are connected to a wireless network. The disclosed methods and apparatuses deals with independently controlling transmission power of SRS signals and signals comprising traffic data from the user equipment (1400). Thereby, it is possible to use different power levels for SRS signals intended to e.g. a macro node and for traffic data intended to e.g. a pico node.
