摘要: A transmission node includes a digital front-end device that provides functional clocks for JESD204B based data transmission. The front-end device includes a PLL for generating a phase locked clock based on a device clock of the front-end device, a clock dividing unit for generating the functional clocks by dividing the phase locked clock, a clock gating unit connected between the PLL and the clock dividing unit, and a system reference signal sampling unit for timing radio frame boundaries. The clock gating unit gates the phase locked clock to align the functional clocks with the device clock within a predetermined number of cycles of the phase locked clock, upon locking of the PLL or receipt of a system resynchronization request. The system reference signal sampling unit samples the system reference signal with zero-cycle latency between device clock and phase locked clock.

摘要: A transmission node for use in a wireless communication network includes a first register for storing a set of first mask bits, a second register for storing a set of second mask bits, and a mask switching block for multiplexing the set of first mask bits and the set of second mask bits and outputting the set of third mask bits. The transmission node further includes a CPRI unit with an auxiliary interface for receiving the set of third mask bits. An activation block is connected between the CPRI unit and the mask switching block for causing the mask switching block to output the set of second mask bits based on data in a current frame in the CPRI unit.

摘要: Adding a new subsystem node to a multi-node base station topology (e.g., a chain or tree topology) in a telecommunications network can disrupt the effective operation of the existing multi-node base station. By accurately measuring the timing difference between uplink and downlink signaling across a current terminating node during the configuration of the new terminating node, the new node can be added with reduced impact upon the operation of the existing base station nodes.

摘要: A transmission node for use in a wireless communication network includes a first CPRI unit for transmitting auxiliary data to a second CPRI unit in the transmission node. A memory unit stores control word data of the auxiliary data. A memory write block is connected between the first CPRI unit and the memory unit for writing the control word data to the memory unit based on a first set of frame timing signals received from the first CPRI unit. A memory read and merge block is connected to the memory unit for reading the control word data stored in the memory unit based on a second set of frame timing signals, merging the control word data with IQ data, and transmitting the merged auxiliary data to the second CPRI unit.
