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.

A communication apparatus that includes a first communication unit for connecting to another communication apparatus and communicating by using a PCR (Primary Connectivity Radio) function in compliance with the IEEE802.11ba standard and a second communication unit for communicating with the other communication apparatus by using a WUR (Wake Up Radio) function in compliance with the IEEE802.11ba standard, the apparatus obtains, from a signal received from the other communication apparatus by the second communication unit, a value indicating a signal intensity or a signal quality of the signal, and sets, based on the obtained value, a transmission rate of the first communication unit.

Aspects of this disclosure relate to forming clusters of user equipments and network nodes. A first cluster of first user equipments and first network nodes in a first section can be formed for a time slot. A second cluster of second user equipments and second network nodes in a second section can be formed for the time slot such that the first user equipments are protected from interference associated with the second cluster. During the time slot, the first section has higher priority than the second section. Multiple-input multiple-output wireless communications can occur during the time slot (a) from the first network nodes to the first user equipments and (b) from the second network nodes to the second user equipments.

A non-terrestrial network (NTN) node transmits configuration information including an indication of a maximum transmission block size (TBS) for a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH). A TBS for the PUSCH or PDSCH is determined based on at least the indicated TBS, and one of a signal indicates one of a maximum modulation and coding scheme (MCS) for the PUSCH or PDSCH transmission or whether the PUSCH or PDSCH transmission uses a default MCS, or the MCS is determined based on at least the indicated maximum MCS, and the PUSCH is transmitted or the PDSCH is received based on the determined TBS and the determined MCS. A maximum TBS, a maximum MCS, or a number of hybrid automatic repeat request (HARD) processes is indicated by a master information block (MIB), a system information block (SIB), or radio resource control (RRC) signaling.

A system, method and computer program of upspeeding a media stream transmitted over a communication link from a sender device to a receiving device.

Artificial intelligence procedures are disclosed for localizing faults in corrupted messages in 5G and 6G, and for correcting those faults based on measured parameters such as backgrounds and message signals. Message faults can be caused by noise or interference from a variety of sources with a wide range of properties. An AI model with multiple adjustable variables may be “trained” using a large number of message events, including faulted messages, to determine which message elements are likely faulted, based on input parameters such as modulation quality, SNR, and other signal properties. The receiving entity can then attempt a grid search to correct the faulted message elements, or request a retransmission. For field use by base stations and user devices, an algorithm may be developed based on the AI model, and configured to predict which message elements are likely faulted. By detecting and correcting message faults, networks may increase reliability and reduce latency while avoiding most retransmission costs and delays, according to some embodiments.

A system is disclosed for adaptively controlling transmission rate between first and second terminals. The system comprising a controller and a transmit unit. The controller comprising a computing unit, a storage unit and a memory unit. The transmit unit is to transmit signals over a communication link from the first terminal to the second terminal and the computing unit is adapted to receive indication of a signal-to-noise-ratio (SNR) of transmission in the communication link and to execute program stored in the memory unit to change the transmission rate of the transmit unit in response to changes in the SNR.

A determination is made whether each predetermined bit of a plurality of predetermined bits of a Semi-Persistent Scheduling (SPS) scheduling assignment for a user equipment (UE) has a respective predetermined value required to validate the SPS scheduling assignment. In circumstances where each predetermined bit of the plurality of predetermined bits of a Semi-Persistent Scheduling (SPS) scheduling assignment is determined to have a respective predetermined value required to validate the SPS scheduling assignment, an action corresponding to SPS is performed. In circumstances where at least one predetermined bit of the plurality of predetermined bits of an SPS scheduling assignment is determined to fail to have a respective predetermined value required to validate the SPS scheduling assignment, the SPS scheduling assignment is discarded and the action is not performed.

This specification describes an apparatus relating to rate adaptation. The apparatus may comprise a processor and a memory including instructions, the instructions, when executed by the processor, cause the apparatus to provide first data representing an estimate of a communications link based on a signal received over said communications link from a transmitter. The apparatus may determine an estimated achievable data rate over said communications link for each of a plurality of link configurations which have respective combinations of modulation scheme and pilot symbol pattern which correspond to one or more transmitter link configurations, the estimated achievable data rate for a particular link configuration being determined based on the first data, and the modulation scheme and the pilot pattern of the particular reference link configuration. The apparatus may select a transmitter link configuration based on the estimated achievable data rates.

The device establishes a first connection between an active HWD radio-frequency integrated circuit (RFIC) and an active console RFIC. The device compares a modulation and coding scheme (MCS) of the first connection to an MCS threshold. The device performs MCS measurements for a second connection of at least one of an idle HWD RFIC or an idle console RFIC, while the first connection is maintained, in response to the MCS not satisfying the MCS threshold. The device compares the MCS measurements of the second connection to the MCS threshold. The device switches to the second connection when at least one of the one or more MCS measurements satisfies the MCS threshold and/or above the MCS of the first connection.
