Abstract: Certain embodiments may relate to communication systems, and, for example, some embodiments may relate to multi-QoS level uplink grants. According to a first embodiment, a method may include transmitting, by a first network entity, one or more grants of one or more uplink resources to a second network entity. The one or more grants of one or more uplink resources includes one or more physical resource allocation parameters containing one or more logical channel groups. The method may further include receiving, by the first network entity, data from the second network entity allocated according to the one or more logical channel groups.

Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell. The message may inform the base station of the source cell that an autonomous handover is initiated. The method may also include initiating the sending of the message to the base station of the source cell during the duration of time Tamer to indicate of the measurement condition. In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.

Abstract: The present disclosure relates to on transition to another cell without handover in non-terrestrial network (NTN). In particular, a NTN device transmits information related to a set of NTN devices to a terminal a first device receives assistance information of a NTN device from a second device. The assistance information at least indicated a type of a cell switching. The first device skips buffer flushing and security key updating regardless of the type of cell switching. In this way, it can achieve cell switching without handover.

Abstract: The present disclosure relates to PDCCH repetition. In particular, a network device transmits system information that includes a parameter related to a PDCCH common search space set with repetition to a terminal device. The terminal device determines a configuration of the PDCCH common search space set with repetition based on the parameters. The terminal device 110 further monitors a set of repetitions of a PDCCH based on the configuration. In this way, it can improve the coverage enhancement.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium of enhancements on uplink transmission. The method comprises: transmitting, to a second device, a first group of transmission repetitions based on first uplink synchronization information: prior to transmitting a second group of transmission repetitions, determining second uplink synchronization information based on system broadcast information for deriving transmission compensation in at least one of time domain and frequency domain; and transmitting, to the second device and based on the second uplink synchronization information, the second group of transmission repetitions. The method helps guarantee the effective receipt of uplink repetitions with compensation jump in time or frequency domain or update due to changing of uplink synchronization information. In addition, the network knows how to combine or select repetitions for best performance when the UE automatically adjusts the UL compensation in time or frequency domain during the repetitions.

Abstract: Techniques for signalling TA adjustment during RTT measurement in non-terrestrial networks relayed connection between nodes are provided. For example, a method performed by a terminal node in a non-terrestrial network, comprises: performing a timing advance (TA) adjustment during a round trip time (RTT) measurement; and in response to the TA adjustment exceeding a threshold, providing, to a network node, an indication relating to the RTT measurement to indicate that the TA adjustment exceeds the threshold.

Abstract: A method, apparatus, and computer program product are disclosed for reporting time and frequency compensation updates to a base station in a 5G network. In this regard, an example method is configured to determine an actual time domain window based at least in part on a time domain window received at the user equipment from a base station, and on at least one adjustment to at least one of time or frequency of a reference signal due to a physical characteristic of a transmission environment. The example method may further cause a compensation report to be transmitted to the base station in a control channel message within the uplink communication stream. The compensation report includes an indication of the at least one adjustment. The method further causes the reference signal to be transmitted in the actual time domain window to the base station.
