摘要： A node of a wireless network transmits information to a user equipment over an aggregated carrier that includes a primary carrier having a first set of primary carrier time/frequency resources and a secondary carrier having a second set of secondary carrier time/frequency resources. Synchronization signals and/or reference symbols are transmitted to the user equipment on the secondary carrier less often than on the primary carrier. An indication of when and/or how often the synchronization signals and/or reference symbols will be transmitted to the user equipment on the secondary carrier may also be transmitted to the user equipment over the primary carrier. By transmitting synchronization signals and/or reference symbols to the user equipment on the secondary carrier less often than on the primary carrier, resources of the secondary carrier may be conserved, energy efficiency of the secondary carrier may be increased, and/or interference with other cells may be reduced or prevented.

摘要： The scheduling flexibility of CSI reference signals enables time and frequency synchronization using multiple non-zero CSI-RSs transmitted in the same subframe, or using CSI-RSs transmitted in the same subframe with other synchronization signals. Also, multiple synchronization signals may be scheduled in the same subframe to enable fine time and frequency synchronization without cell-specific reference signals.

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： 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 sends uplink control information from a user equipment to a serving node of a radio communications system by first encoding uplink control information bits into symbols. The encoded symbols are split into at least two groups of symbols for use to achieve diversity transmission. Each of the at least two groups of symbols are cyclically repeated to generate a repeated group for each of the at least two groups of symbols. Then the repeated groups are mapped each to different transmission ports of the user equipment for diversity transmission as uplink control information through a plurality of uplink transmission slots of an uplink subframe.

摘要： Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-overlapping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs). When user equipment (UE) demodulates the information it receives in a particular region of a resource block (RB), it uses the reference symbol (RS) associated with that region. The reference symbol (RS) information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

摘要： The invention relates to random access procedures in an LTE-system applying carrier aggregation, in particular to support network-initiated random access on secondary cells. A UE transmits a preamble on a random access channel to a radio base station on a secondary cell and receives or detects a random access response message from the base station including timing advance information for uplink transmission by the UE. The UE can determine the secondary cell that the control information in the random access response message refers to and transmits to the base station based on the timing advance information in the random access response message.
