Systems and methods for packet re-transmission via a bi-directional wired interface between two devices are provided. A transmitter of a first device transmits one or more first transmit data packets to a second device over the bi-directional wired interface. Concurrently with the transmission of the one or more first transmit data packets, the first device receives, over the bi-directional wired interface, one or more second received data packets from the second device. A packet integrity monitor of the first device monitors whether one or more received data packets of the second received data packets is corrupted at the physical layer of the first device. In response to detecting that one or more received data packets of the second received data packets is corrupted, the first device re-transmits one or more transmit data packets of the first transmit data packets that was previously transmitted over the bi-directional wired interface.

An apparatus may comprise a processing resource operatively coupled to a memory resource and a frame determination component operatively coupled to the processing resource and the memory resource. The frame determination component may cause a counter corresponding to a particular station associated to the apparatus to be stored in the memory resource, the counter to be incremented in response to receipt of a transmission frame containing an invalid starting sequence number (SEN) and a deauthentication frame to be transmitted in response to receipt of a threshold number of transmission frames containing the invalid.

Systems and devices can include protocol stack circuitry to perform certain methods, including receiving a flow control unit (flit) header and a transaction layer packet (TLP) payload, the TLP payload comprising a first portion and a second portion, determining that the flit header is free from errors, forwarding the flit header and the first portion of the TLP payload to a link partner based on the flit header being free from errors, identifying that the flit contains an error from the second portion of the TLP payload, and sending a data link layer packet (DLLP) to the link partner to indicate the error in the TLP payload.

The present disclosure describes methods and apparatuses for inter-radio access technology carrier aggregation. In some aspects, a user device establishes a wireless link for communicating with a base station via a first radio access technology. The user device receives an inter-radio access technology carrier aggregation communication via the wireless link in accordance with the first radio access technology. The inter-radio access technology carrier aggregation communication includes data relating to a component carrier of the wireless link that uses a second radio access technology. The user device may use the data to configure the user device for communication via the second component carrier of the wireless link.

A method and system for selecting a symbol detector are herein provided. A method includes extracting a first set of features for a k-th resource element (RE), where k is an integer greater than one, extracting a second set of features from a first RE to a (k1)th RE, and selecting a symbol detector for the k-th RE using a reinforcement learning (RL) neural network based on the extracted first set of features and the extracted second set of features.

A method for delivering payloads through an interface includes receiving an out-of-sequence data transfer unit, DTU; segmenting the out-of-sequence DTU into at least one data unit; determining at least one priority level of the at least one data unit; and for any particular data unit among the at least one data unit, (1)s electively forwarding a payload of the particular data unit to the interface in response to priority level thereof satisfying a priority condition; or (2) holding the particular data unit in response to the priority level thereof not satisfying the priority condition.

A processing device includes an internal transmitter to receive packets and to forward those packets across a link to an external receiver external to the processing device. The internal transmitter is to receive a portion of a packet and to begin transmitting the portion across the link to the external receiver before the entire overall packet, of which the portion is a part, is received and validated. For a packet determined to have an error, the internal transmitter does not resend the overall packet across the link even if a message is received from the external receiver to resend the overall packet.

According to various examples, a communication device is described comprising a memory configured to store data received in one or more first transmissions of a transmission process according to a retransmission protocol, a receiver configured to receive a second transmission of data of the transmission process, a combiner configured to combine the data received in the second transmission with the data stored in the memory, a determiner configured to determine whether the second transmission was interfered by a communication resource deallocation and a controller configured to maintain data storage of the received data of the transmission process stored in the memory as received data of the transmission process if the second transmission was interfered by a communication resource deallocation.

Techniques for guided placement of a wireless device are described herein. In an example embodiment, a wi-fi wireless device comprises a radio frequency (RF) transceiver coupled to a baseband processor. The RF transceiver is configured to receive an RF signal transmitted over a wireless channel and to convert the RF signal to a modulated digital signal. The baseband processor is configured to receive the modulated digital signal from the RF transceiver, extract a wireless packet from the modulated digital signal, and compute an Exponential Effective SNR Mapping (EESM) value based on the preamble of the wireless packet, where the computed EESM value indicates the quality of the wireless channel at the current location of the wireless device. The baseband processor is further configured to provide a quality indicator based on the EESM value for the current location of the wireless device.

Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and performing error detection and correction on the message. Such a method can also include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.
