The UE receives, from the BS, a first downlink control information (DCI) indicating a first uplink resource for transmitting a first uplink signal, and then receives, from the BS, a second DCI indicating a second uplink resource for transmitting a second uplink signal. The BS configures the second uplink resource to be advanced to the first uplink resource in the time domain based on the uplink out-of-order configuration. The UE decides the transmission of the first uplink signal according to the condition of resource configuration.

The serving source configuration indicates a plurality of serving sources. The BS generates a first downlink signal and a second downlink signal based on a piece of downlink information. The first downlink signal carries a first part of the piece of downlink information and the second downlink signal carries a second part of the piece of downlink information.

Base station and user equipment for mobile communication system

A user equipment determines a repetition sequence including a plurality of repetitions. The user equipment schedules the repetition sequence in a time slot or in a plurality of consecutive time slots, wherein at least one of the plurality of consecutive time slots is arranged to at least two of the plurality of repetitions. Then, the user equipment transmits the plurality of repetitions to a base station.

User equipment and method for performing repetition

A base station (BS) for a mobile communication system is provided. As for a user equipment (UE), the BS is a primary BS and connects to a secondary BS. The primary BS calculates the time synchronization error between the primary BS and the UE, and the time synchronization error between the secondary BS and the UE. These time synchronization errors are associated with the subcarrier spacings (SCSs) of the primary and secondary BSs, respectively. According to the calculated time synchronization errors, the primary BS transmits a synchronization indication message to instruct the UE to receive the reference time information of one of the primary and secondary BSs.

Base station for mobile communication system

A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE performs a random access (RA) procedure with the BS in a radio resource control (RRC) idle mode. The UE transmits a preconfigured uplink resource request message to the BS and receives a configuration message indicating a preconfigured uplink resource from the BS. The UE starts a time alignment timer (TAT) which is used for the RRC idle mode in response to the RA procedure. When the UE determines that there exists an uplink message to be transmitted in the RRC idle mode and determines that the current timing advance (TA) value is valid, the UE transmits the uplink message on the preconfigured uplink resource.

A base station (BS) and a user equipment (UE) for a mobile communication system are provided. The BS generates first downlink information (DCI) related to a first service type and transmits the first DCI indicating a first physical uplink control channel (PUCCH) resource to the UE. The BS further generates second DCI related to a second service type and transmits the second DCI indicating a second PUCCH resource to the UE. The first service type and the second service type have different priorities. The starting symbol of the first PUCCH resource is located within a first type assigned sub-slot of a plurality of first type sub-slots of a slot, and the starting symbol of the second PUCCH resource is located within a second type assigned sub-slot of a plurality of second type sub-slots of the slot.

The UE divides a plurality of uplink radio resources into at least one group and determines whether there exist pieces of uplink information corresponding to the uplink radio resources. When the corresponding pieces of the uplink information exist, the UE determines whether there exist overlapped periods in the time domain among the corresponding uplink radio resources. For any two of the corresponding uplink radio resources having the overlapped period, the UE decides how to transmit the corresponding pieces of uplink information based on whether the two of the corresponding uplink radio resources belonging to the same group or not, whether the corresponding pieces of uplink information can be jointly transmitted or not, and the priorities of the uplink information.

The base station transmits, in response to the UL transmission of the UE, a beam configuration message to the UE, so as to configure a first DL Tx beam associated with the first UL beam recovery resource into the beam pair links.
