A method for waking up, from a low-power mode, a first communications node coupled to a second node via a first communication link, includes determining, while the first node is awake, a first transmission rate for transmitting data over the first link, storing the first rate at the second node, and selectively transmitting, from the second node to the first node, a first wake-up command at a symbol rate corresponding to the first rate. Where a third node is coupled to the second node via a second link, the method may further include determining, at the second node, while the third node is awake, a second transmission rate for transmitting data over the second link, storing the second rate at the second node, and selectively transmitting, from the second node to the third node, a second wake-up command at a symbol rate corresponding to the second rate.

A method for determining transmission rate, an apparatus, a transmission device, and a storage medium. The method includes: determining at least two candidate transmission rates; performing data transmission for a period of time at each of the candidate transmission rates; determining an energy utilization rate of battery power during the data transmission at each of the candidate transmission rates; and selecting a target transmission rate for subsequent data transmission from the candidate transmission rates according to the energy utilization rate.

A method for data communication between a first node and a second node includes forming one or more redundancy messages from data messages at the first node using an error correcting code and transmitting first messages from the first node to the second node over a data path, the transmitted first messages including the data messages and the one or more redundancy messages. Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.

A platform for updating one or more properties of one or more digital twins including receiving a request for one or more digital twins; retrieving the one or more digital twins required to fulfill the request from a digital twin datastore; retrieving one or more dynamic models corresponding to one or more properties that are depicted in the one or more digital twins indicated by the request; selecting data sources from a set of available data sources based on the one or more inputs of the one or more dynamic models; obtaining data from selected data sources; determining one or more outputs using the retrieved data as one or more inputs to the one or more dynamic models; and updating the one or more properties of the one or more digital twins based on the one or more outputs of the one or more dynamic models.

A device includes a transmitter coupled to a node, where the node is to couple to a wired link. The transmitter has a plurality of modes of operation including a calibration mode in which a range of communication data rates over the wired link is determined in accordance with a voltage margin corresponding to the wired link at a predetermined error rate. The range of communication data rates includes a maximum data rate, which can be a non-integer multiple of an initial data rate.

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.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

In one aspect, a system includes an electronic control unit (ECU) and an integrated circuit (IC). The IC is configured to transmit, to the ECU, absolute data on a message line at a first rate; and transmit, to the ECU, incremental data on an index line at a second rate. The second rate is faster than the first rate and the incremental data includes data associated with changes in the absolute data.
