There is provided mechanisms for radio link adaptation at a transmit and receive point. A method is performed by a network node. The method includes obtaining LLR values for a block of codewords. The LLR values are output from an information decoder decoding the block of codewords. The block of codewords has been communicated over a radio link between the transmit and receive point and a terminal device. The method includes performing radio link adaptation of the radio link depending on the LLR values by selecting radio link adaptation parameter values. Which radio link adaptation parameter values to select depends on the LLR values.

Methods and apparatus relating to lane based normalized historical error counter view for faulty lane isolation and disambiguation of transient versus persistent errors are described. In an embodiment, a plurality of storage entries store error information to be detected at one or more physical lanes of an interface. Faulty lane detection logic circuitry determines which of the one or more physical lanes is faulty or more likely to be faulty based at least in part on the stored error information for the one or more physical lanes of the interface. The stored error information comprises historical error details for the one or more physical lanes of the interface. Other embodiments are also disclosed and claimed.

This document generally relates to transmitting a feedback message from a first node to a second node, where the message indicates both a detection result of receiving at least a portion of a transport block, and addition information that indicates to the second node how to set one or more parameters for a subsequent transmission. In various embodiments, the message includes a value, such as an M-bit binary value that indicates both the detection result and the additional information.

The method includes: determining N channel state information reports; and sending M of the N channel state information reports based on priorities of the N channel state information reports, where both N and M are positive integers greater than or equal to 1, and M is less than or equal to N; and a priority of a channel state information report in the N channel state information reports.

Methods, systems, and devices for wireless communications are described for identifying a file having a set of packets that are configured to be processed together. The base station may determine a segmentation scheme for the file based on a size of the file and identify a batch of assignments for communicating the file via a batch of transmissions based on the segmentation scheme. The base station may communicate the file via the batch of transmissions with a user equipment (UE) during the batch of assignments. Additional techniques are described herein for a UE to identify that the UE is storing a file in a buffer at the UE. The UE may transmit an indication to the base station that the buffer includes the file. In some cases, the UE may indicate a size of the file.

Examples of techniques for dynamically controlling data bursts are described. In an example, an access point (AP) monitors a link quality between the AP and a client device associated with the AP. The AP determines a channel occupancy of a channel in which the AP is configured to operate. In response to determining that the channel occupancy is less than a channel busy threshold, the AP modifies a burst duration for traffic flow between the AP and the client device based on the link quality. The AP communicates with the client device using the channel for the modified burst duration.
