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.

摘要： A method in a network node for transmitting an enhanced Control CHannel, eCCH, to a user equipment in a telecommunications system. The eCCH comprises control information to the user equipment in at least one Control Channel Element, CCE. The at least one CCE maps to a number of resource elements comprised in at least one enhanced resource element group. The at least one enhanced resource element group is comprised in at least one resource block in a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid. The network node decides to use a CCE aggregation level that is smaller than the smallest CCE aggregation level of a physical downlink control channel, PDCCH, for a first eCCH. The network node then modulates the first eCCH by using a higher order modulation than Quadrature Phase Shift Keying, QPSK, modulation, when the smaller CCE aggregation level is used for the first eCCH. Then, the network node maps the modulated first eCCH to the at least one enhanced resource element group of resource elements in the at least one resource block, and transmits the mapped first eCCH to the user equipment. A network node, a method in user equipment and a user equipment are also provided.

摘要： For uplink cooperation of a serving access node (100-1) and a supporting access node (100-2) with respect to a terminal (200), the serving access node (100-1) requests information relating to an Rx signal (10-2) received from the terminal (200) at the supporting access node (100-2). The requested information may include a baseband representation of the Rx signal (10-2), demodulated bits of the Rx signal (10-2), or decoded bits of the Rx signal (10-2). The supporting access node (100-2) obtains the requested information from the Rx signal (10-2) and sends a response including the information to the serving access node (100-1). The serving base station determines an optimized signal on the basis of the information received from the supporting access node (100-2) and on the basis of corresponding information relating to a signal (10-1) received from the terminal (200) at the serving access node (100-1).
