    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.

    摘要： The impact of a fading dip in a radio channel on the communication between a first and a second antenna may be reduced by receiving a sounding signal at the first antenna or the second antenna over the radio channel and measuring the frequency response of the radio channel using this sound signal that was received. The radio frequency signal that is used to communicate between the first antenna and the second antenna is adjusted in response to the frequency response that was measured in order to reduce an impact of the fading dip in the radio channel on the radio frequency signal during operation. Related systems, methods, and devices are disclosed.

    摘要： An apparatus (20) is associated with a telecommunications node (N) which serves a service area (S) which belongs to one set of plural sets of service areas comprising a network. The apparatus (20) divides a time resource for the node into plural phases in coordinated manner with other service areas. The apparatus (20) further generates a schedule for transmission/reception of user traffic for wireless terminals served by the node for plural consecutive phases. The schedule is generated so that during the plural consecutive phases the node can transmit and receive scheduled user traffic before receiving in the plural consecutive phases scheduling information from another node which serves another set of service areas.

    摘要： Code words are assigned to subscriber stations or groups of subscriber stations in a communication network for a quick paging mechanism in which the assigned code words are transmitted as quick paging signals over unused frequency resources to signal the subscriber stations. Subsets of multiple code words from a set of code words can be assigned to respective paging groups, and overlapping subsets can be assigned to multiple paging groups. This enables a single code word to be used to address either a single paging group or multiple paging groups.
