Link establishment between a radio equipment controller (REC) and radio equipment (RE) in a fronthaul network

Techniques that provide link establishment between a radio equipment controller (REC) and a radio equipment (RE) in a fronthaul network are described herein. In one embodiment, a method includes performing, Common Public Radio Interface (CPRI) Layer 1 (L1) link auto-negotiation operations to establish a CPRI link between the REC and RE. A proxy slave may achieve a hyper frame number (HFN) synchronization with the REC at a link bit rate for a first CPRI bit stream and communicate the first CPRI bit stream and the link bit rate to a proxy master. The proxy master may communicate a second CPRI bit stream to the proxy slave to transmit to the REC. The L1 link auto-negotiation operations are completed and CPRI link is established between the REC and the RE when the REC achieves a HFN synchronization for the second CPRI bit stream.

Synchronization signal periodicity adjustment

Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.

Systems and methods for positioning reference signal staggering configuration

Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.
