Abstract: A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.

Abstract: A BS determines an amount of resource overloading for a contention transmission unit (CTU) access region associated with a grant-free uplink transmission scheme in a multiple access system. The BS determines a modulation and coding scheme (MCS) limit indicating a maximum MCS level for the CTU access region. The BS sends the MCS limit to a plurality of user equipments (UEs) associated with the first CTU access region. A UE receives from the base station the MCS limit and determines a first MCS index within the MCS limit for a first uplink transmission. The UE sends the first uplink transmission to the base station using a CTU in the CTU access region. The first uplink transmission includes user data and the first MCS index determined at the first UE.

Abstract: Aspects of this disclosure provide techniques for detecting and recovering from beam-failure events. In some embodiments, motion sensor information generated by motion sensors on a UE is used to detect, predict, and/or recover from a beam failure event that results, or would otherwise result, from movement of the UE. The motion sensor information may be used to adjust a current beam direction used by the UE to transmit or receive a signal, or to determine a recommendation for adjusting a current beam direction of the base station. The motion sensor information may be generated by any sensor that detects a movement of the UE, such as a gyroscope, an accelerometer, a magnetometer, a global positioning system (GPS) sensor, a global navigation satellite system (GNSS) sensor, or any other device that detects a change in position/orientation of the UE.

Abstract: A method for operating a user equipment includes receiving a first frame on a first channel associated with a first beam identified during a beam failure recovery procedure, and determining that an assumed quasi-co-located relationship exists between the first channel and the first beam, and based thereon, decoding the first frame in accordance with a first reference signal on the first channel and using a first spatial domain receive filter that was used to decode the first beam.
