The present disclosure described systems and methods for providing OTT services to a UE. An exemplary OTT-providing host computer includes a transceiver, a processor, and memory collective configured to provide the OTT service by initiating transmission of user data to the UE. To transmit the user data from the host computer to the wireless device, a network node sends a first control message for assigning a PDSCH, the first control message comprising a first MCS indication as described. The network node sends to the wireless device a second control message for assigning a PDSCH, the second control message comprising a second MCS indication as described. The network node transmits the user data thereafter.

A data link error feedback signaling system includes a transmitting network device and a receiving network device. The receiving network device may be operable to receive a network data unit from the transmitting network device over a data link, detect an error in the network data unit, and provide data link integrity information based on the error to the transmitting network device. The receiving network device may provide the data link integrity information by marking the data link flawed in a routing protocol, transmitting the data link integrity information via an informational protocol, and so on. The transmitting network device may respond to the data link integrity information, such as by marking the data link less preferred, marking the data link down, transmitting an alarm regarding the data link to a network operator, omitting taking an action upon determining that errors are below an error threshold, and so on.

A system and method for characterizing performance of a terminal radio. The method includes obtaining a plurality of SNR feedbacks by, for each input power level of varying input power levels of the terminal radio, estimating an SNR (signal-to-noise ratio) associated with a respective input power level for a burst sent from the terminal radio to a gateway, where each of the SNR feedbacks may include an estimated SNR and the respective input power level; and determining a RC (radio characterization) of the terminal radio based on where the SNR feedbacks start deteriorating without indicating a saturated response at the gateway, where bursts are transmitted at a selected frequency with a selected SYMCOD (symbol, modulation and error coding scheme).

A technique for radio transmitting data is described. As to a method aspect of the technique data to be transmitted to a receiver is represented by at least two partial modulation symbols. Each of the at least two partial modulation symbols is associated to a different layer of the radio transmission to the receiver. A modulation symbol is generated by combining the at least two partial modulation symbols at different power levels according to the associated layer. The modulation symbol is transmitted to the receiver.

Embodiments herein relate to e.g., a method performed by a communication node for controlling one or more communication parameters of a channel between a first communication device and a second communication device in a wireless communication network. The communication node, upon obtaining an indication of a channel quality of the channel to the second communication device, uses a correction value and the indication when determining the one or more communication parameters. The correction value is based on a decoding success of one or more previous transmissions, which one or more previous transmissions are based on an obtained previous indication of a previous channel quality from the second communication device, and wherein a change of the correction value relative a previous correction value is limited.

A method for determining channel quality indication (CQI) information, which is implemented by a base station and includes that: determining CQI feedback configuration information of a target user equipment (UE), where the CQI feedback configuration information at least includes CQI feedback configuration information of an interference sub-band and the interference sub-band is a downlink (DL) frequency range involved in intra-device interference; sending the CQI feedback configuration information to the target UE; and determining target CQI information for subsequent DL scheduling based on CQI information, reported by the target UE based on the CQI feedback configuration information, of different bandwidth granularities.

This disclosure provides a resource configuration method. The method includes: receiving, by a terminal, first indication information sent by a network device, where the first indication information is used to indicate S first time units and T second time units, when S≠0, the first indication information further indicates an index value or an identifier of format information of the first time unit; and when T≠0, the first indication information further indicates first set information of the second time unit, the first set information indicates a first set, and the first set includes index values or identifiers of at least two types of format information of the second time unit; and determining, by the terminal, the format information of the first time unit based on the index value or the identifier of the format information of the first time unit, or determining the first set based on the first set information.

This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

Disclosed is a method and performed by a system of a wireless communication network for determining signal quality indications. The method includes determining a correlation between a quality of a signal received at a first wireless device and a quality of a signal received at a second wireless device, obtaining a first indication of quality of a signal received at the first wireless device, and determining a second indication of quality of signals received at the second wireless device based on the first indication and the determined correlation. The system may be implemented in a radio access network node.

A technique for communicating protocol data units, PDUs, in a radio communication from a transmitter (100) to a receiver (200) is described. As to a method aspect of the technique, one or more control messages indicative of Quality of Service, QoS, requirements for the radio communication are received. The QoS requirements include a control command for a reliability of the radio communication and a control command for a latency of the radio communication. A batch of redundant PDUs is transmitted from the transmitter (100) to the receiver (200). A number of the redundant PDUs per batch depends on the control command for the reliability and a temporal spread of the redundant PDUs per batch depends on the control command for the latency.
