    摘要: The present disclosure relates to a user equipment (UE) that comprises a receiver of the UE receives, from a source base station of a source radio cell, a common timing advance value for a target radio cell. The UE is connected to the source radio cell and is involved in a handover procedure to hand over the UE from the source radio cell to the target radio cell. Further, the common timing advance value is received from the source base station in a first message of the handover procedure, which also comprises a timing indication for transmitting a second message from the UE to the target base station. Then, a processor of the UE determines a first uplink timing of uplink transmissions to the target base station with respect to downlink transmissions from the target base station, based on the received common timing advance value and the timing indication. A transmitter of the UE transmits a second message of the handover procedure to the target base station based on the determined uplink timing. The processor determines a UE-specific timing advance value, specific to the UE and the target radio cell, to be used by the UE for performing uplink transmissions in the target radio cell.

    摘要: The present disclosure relates to a user equipment (UE) that comprises a receiver, which receives, from abase station, a minimum cross-slot time-domain scheduling parameter, indicating a minimum amount of slots between a scheduling downlink control information, DCI, and an uplink or downlink transmission scheduled by the scheduling DCI. The minimum cross-slot time domain scheduling parameter is carried by a DCI message. Processing circuitry of the UE determines an updating time at which a previously-received minimum cross-slot time-domain scheduling parameter is to be updated based on the received minimum cross-slot time-domain scheduling parameter and then updates the previously-received minimum cross-slot time-domain scheduling parameter based on the received minimum cross-slot time-domain scheduling parameter at the determined updating time. The updating time is determined based on a message exchanged between the UE and the base station, wherein the message relates to the DCI message carrying the minimum cross-slot time-domain scheduling parameter.

    摘要: A user equipment, a base station and respective methods are provided. The user equipment receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling, the PUSCH config IE being applicable to a particular bandwidth part. The user equipment configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, at least one row comprising a first set of values related to allocated time-domain resources for a plurality of PUSCH transmissions. The user equipment receives downlink control information (DCI) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The user equipment determines allocated time-domain resources for the plurality of PUSCH transmissions based on the index of the slot carrying the received DCI.

    摘要: The present disclosure provides a transceiver device and scheduling device, and communication methods for transceiver device and scheduling device. The transceiver device comprises a transceiver which, in operation, receives, over a physical downlink control channel (PDCCH), a sub-band occupancy indicator indicating sub-bands determined to be available for a transmission, and a resource allocation indicator indicating resources included in the available sub-bands and assigned to the transceiver device for the transmission. The transceiver device further comprises circuitry which, in operation, determines the assigned resources according to the resource allocation indicator and the sub-band occupancy indicator.

    摘要: Provided is a terminal that can appropriately transmit an uplink signal. In a terminal (200), a control unit (211) determines a processing mode with respect to uplink data and uplink control information according to a requirement for at least one of uplink data and uplink control information when transmission of an uplink data channel that includes the uplink data and transmission of an uplink control channel that includes the uplink control information temporally overlap. A transmission unit (218) transmits the at least one of the uplink data and the uplink control information on the basis of the determined processing mode.

    摘要: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a control unit (211) determines a processing format for a response signal or for an uplink control channel used for transmission of the response signal, in accordance with request conditions for a response signal of downlink data. A transmission unit (216) uses the uplink control channel to transmit the response signal on the basis of the determined processing format.
