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： A node of a wireless network includes processor circuitry that is configured to obtain an identification of a cell on which a user equipment shall transmit a random access preamble and to encode the identification of the cell on which the user equipment shall transmit the random access preamble into at least one unused bit position of a physical downlink control channel random access order. A transmitter is responsive to the processor circuitry and is configured to transmit the physical downlink control channel random access order including the identification of the cell that was encoded into the at least one unused bit position of the physical downlink control channel random access order. Related user equipment, systems and methods are also described.

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), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particular region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port 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： 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.
