    摘要： A transmitting node uses different reference signal sequences for different types of enhanced control channels. An example method begins with generating (1410) a first reference signal sequence, from a first initialization value, and generating (1420) a second reference signal sequence, from a second initialization value. These reference signal sequences are associated with two corresponding enhanced control transmissions. A first enhanced control channel and reference symbols taken from the first reference signal sequence are transmitted (1430), using first time-frequency resources and a first set of transmission points or a first set of antenna ports or both, and a second enhanced control channel and reference symbols taken from the second reference signal sequence are also transmitted (1440), using a differing second set of transmission points and/or a differing second set of antenna ports and/or a differing second set of time-frequency resources, in the same subframe or group of subframes.

    摘要： A method in a user equipment device for estimating a channel upon receiving an enhanced control channel (eCCH) from a network node in a telecommunications system includes distributing the eCCH over multiple resource pairs, where each of the multiple resource block pairs includes a number of resources. Each of the resources is associated with a respective antenna port. The user equipment device identifies an antenna port that is associated with multiple ones of the resources. The multiple ones of the resources are present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. Identifying the antenna port is based on how the eCCH is mapped to the multiple resource block pairs. The user equipment device estimates the downlink channel for the eCCH based on the identified antenna port in the multiple ones of the resources in the multiple resource block pairs.

    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： A method in a user equipment (121) for determining a transport block size is provided. The transport block size is used by the user equipment (121) in receiving downlink data transmissions from a network node (110) on an enhanced Control CHannel, eCCH. The user equipment (121) and the network node (110) are comprised in a telecommunications system (100). The user equipment (121) has access to a table of predetermined transport block sizes. The user equipment (121) may calculate an indicator NPRB based on the total number of PRBs allocated to the downlink data transmission NPRB, and based on an PRB offset value OPRB or a PRB adjustment factor APRB. Then, the user equipment (121) may determine the transport block size from the table of predetermined transport block sizes based on at least the calculated indicator NPRB. A user equipment, a method in network node and a network node are also provided.
