Terminal and radio communication method for transmission of a transport block over multi-slot
A terminal receives control information indicating allocation of a physical uplink shared channel in a time domain and allocates the physical uplink shared channel across multiple slots. Based on the control information, the terminal determines a transport block to be transmitted over the physical uplink shared channel.
1 . A terminal comprising:
a transmitter that transmits a transport block using a physical uplink shared channel across a plurality of slots;
a receiver that receives information included in a PUSCH-ConfigCommon information element regarding the transmission of the transport block across the plurality of slots and indicating the number of slots to which the transport block is allocated and a number of repetitions; and
a processor that determines the size of the transport block to be transmitted in the plurality of slots based on the information indicating the number of slots,
wherein the processor allocates the same number of symbols to the physical uplink shared channel in each of the plurality of slots, and
wherein the processor controls the transmitter to repeat transmission of the transport block by the physical uplink shared channel across the plurality of slots based on the number of repetitions indicated in the information.
2 . A radio communication method for a terminal comprising:
transmitting a transport block using a physical uplink shared channel across a plurality of slots;
receiving information included in a PUSCH-ConfigCommon information element regarding the transmission of the transport block across the plurality of slots and indicating the number of slots to which the transport block is allocated and a number of repetitions;
determining the size of the transport block to be transmitted in the plurality of slots based on the information indicating the number of slots;
allocating the same number of symbols to the physical uplink shared channel in each of the plurality of slots; and
repeating transmission of the transport block by the physical uplink shared channel across the plurality of slots based on the number of repetitions indicated in the information.
3 . A base station comprising:
a receiver that receives a transport block from a terminal using a physical uplink shared channel across a plurality of slots;
a transmitter that transmits information included in a PUSCH-ConfigCommon information element regarding the transmission of the transport block across the plurality of slots and indicating the number of slots to which the transport block is allocated and a number of repetitions to the terminal; and
a processor that assumes that the terminal determines the size of the transport block to be transmitted in the plurality of slots based on the information indicating the number of slots and allocates the same number of symbols to the physical uplink shared channel in each of the plurality of slots,
wherein the processor controls the receiver to repeat reception of the transport block by the physical uplink shared channel across the plurality of slots based on the number of repetitions indicated in the information.
4 . A radio communication system comprising a terminal and a base station, wherein
the terminal comprises:
a transmitter that transmits a transport block to a base station using a physical uplink shared channel across a plurality of slots;
a receiver that receives information included in a PUSCH-ConfigCommon information element regarding the transmission of the transport block across the plurality of slots and indicating the number of slots to which the transport block is allocated and a number of repetitions from the base station; and
a processor that determines the size of the transport block to be transmitted in the plurality of slots based on the information indicating the number of slots and assigning the same number of symbols to the physical uplink shared channel in each of the plurality of slots,
wherein the processor controls the transmitter to repeat transmission of the transport block by the physical uplink shared channel across the plurality of slots based on the number of repetitions indicated in the information, and wherein
the base station comprises:
a receiver that receives the transport block from the terminal using the physical uplink shared channel across the plurality of slots; and
a transmitter that transmits to the terminal information indicating the number of slots to which the transport block is assigned and the number of repetitions.
