Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.

Some techniques and apparatuses described herein enable a user equipment (UE) to autonomously modify one or more transmission parameters, other than a transmit power, for uplink communications after detecting a change in pathloss. The UE may modify the one or more transmission parameters without receiving instructions from a base station, such as in downlink control information, with updated value(s) for the one or more transmission parameters. As a result, the UE and the base station avoid the round trip delay that would otherwise be required to modify the transmission parameter(s) and perform link adaptation. Some techniques and apparatuses described herein apply to non-terrestrial networks with a large round trip delay. Other aspects are described.

Selecting a control channel set in a communication system involves monitoring received signals to identify a plurality of nodes of interest (NOI) and determining E.sub.b/N.sub.0 values for a plurality of control channels. For this purpose, a data metric and spectral data can be provided to the communication device by the respective NOI for which E.sub.b/N.sub.0 values are being determined. A comparison is made of the E.sub.b/N.sub.0 values for all NOI to select an optimal control channel set. The optimal control channel set is then used by the communication device to transmit the control channel information to the plurality of NOI.

A communication system includes multiple distributed antenna circuits and an access point (AP). The distributed antenna circuits include at least first and second antenna circuits. The AP is coupled to the distributed antenna circuits and includes multiple transmit chains, multiple receive chains, and an antenna control circuit communicatively coupled to the transmit chains and the receive chains. The first antenna circuit is co-located with the AP and the second antenna circuit is remote from the AP. The antenna control circuit is configured to determine a subset of the distributed antenna circuits to communicatively couple to at least some of the transmit chains to transmit data to a wireless station (STA) that is in range of the subset.

For example, a wireless communication station (STA) may be configured to generate a plurality of encoded-modulated data streams based on a data field of a PPDU to be transmitted over a channel BW. For example, the plurality of encoded-modulated data streams may be configured based on a plurality of channel BW segments in the channel BW. For example, the plurality of encoded-modulated data streams may include a first encoded-modulated data stream according to a first Modulation and Coding Scheme (MCS) corresponding to a first channel BW segment, and a second encoded-modulated data stream according to a second MCS, e.g., different from the first MCS, corresponding to a second channel BW segment. For example the STA may be configured to transmit a plurality of transmissions based on the plurality of encoded-modulated data streams over the plurality of channel BW segments.

A method and system to control modulation and coding scheme (MCS) used for air-interface communication over an air interface between an access node and one or more user equipment devices (UEs) served by the access node. A method includes detecting that a backhaul connection through which the access node communicates is threshold heavily loaded, and, in response, suppressing the MCS used for air-interface communication over the air interface between the access node and one or more UEs served by the access node. Further, the method could apply in a scenario where multiple access nodes share the backhaul connection, in which case one access node could detect that the backhaul connection is threshold heavily loaded and could responsively cause another access node to suppress MCS used for the other access node's air-interface communication.

A wireless device receives, during a discontinuous reception (DRX) active time of a DRX operation of the wireless device, a response to a message that comprises a preamble and a transport block. The DRX active time is determined based on a time window that starts at least one symbol after a transmission occasion of the transport block.

A method, performed by a first base station, of sharing a frequency resource with a second base station in a wireless communication system is provided. The method includes transmitting, to channel measurement target terminals determined from among terminals communicating with the first base station using first frequency resources, information instructing to transmit a signal for channel measurement to the second base station; transmitting, to the second base station, information indicating that the signal for channel measurement is to be transmitted from the channel measurement target terminals; receiving, from the second base station, measurement information about channels between the second base station and the channel measurement target terminals; determining a shared frequency resource to be shared with the second base station from among the first frequency resources, based on the measurement information about the channels between the second base station and the channel measurement target terminals; and transmitting information about the shared frequency resource to the second base station.

Methods, systems, and devices for wireless communications are described that provide for scheduled communications in which multiple different communication instances may be scheduled between a user equipment (UE) and a base station. Different communication parameters for different communication instances may be selected based on one or more factors, such as channel conditions or a number of prior uplink transmissions. The base station may provide the UE with two or more sets of communication parameters for scheduled communications, and a set of communication parameters may be selected at both the base station and the UE based on channel conditions meeting a defined threshold value, or based on a number of uplink transmissions in a prior time window meeting a defined threshold number.

Artificial Intelligence (AI) can rapidly evaluate a faulted message in 5G or 6G, calculate a likelihood that each message element is faulted, and optionally suggest a most probable corrected version for each of the likely faulted message elements. To do so, the AI takes in numerous factors besides the message itself, such as the modulation quality of each message element, the proximity and quality of a nearest demodulation reference, a signal-to-noise ratio of the message element, a measure of current electromagnetic noise during the message element, an expected format or expected codewords based on prior messages or convention, and other factors. The AI model can then provide guidance as to mitigation, such as choosing whether to request a retransmission or attempting to vary the likely faulted message elements. The AI model can be adapted to fixed-site computers or to the more limited computers of a mobile user device.
