Abstract
A transmission control method includes: transmitting, on a primary component carrier, a first physical downlink shared channel (PDSCH) to a terminal, and determining a first process identifier (PID) of a hybrid automatic repeat request (HARQ) corresponding to the first PDSCH; and before HARQ information of the first PID transmitted by the terminal is received on a secondary component carrier, not transmitting a second PDSCH to the terminal. Where a PID of an HARQ corresponding to the second PDSCH is the same as the first PID, and the secondary component carrier is provided for the terminal to transmit an HARQ of the PID.
Claims16
A transmission control method, performed by a base station and comprising:
- transmitting, on a primary component carrier, a first physical downlink shared channel (PDSCH) to a terminal, and determining a first process identifier (PID) of a hybrid automatic repeat request (HARQ) corresponding to the first PDSCH;
- and
- not transmitting a second PDSCH to the terminal until the HARQ information of the first PID sent by the terminal is received on a secondary component carrier,
- wherein a second PID of a second HARQ corresponding to the second PDSCH is the same as the first PID, and the secondary component carrier is provided for the terminal to transmit at least one of the first HARQ corresponding to the first PID or the second HARQ corresponding to the second PID.
A transmission control method, performed by a base station, and comprising:
- transmitting, on a primary component carrier, a first physical downlink shared channel (PDSCH), a second PDSCH, a first trigger message, and a second trigger message to a terminal,
- wherein the first trigger message is configured to trigger the terminal to switch to a secondary component carrier to transmit first hybrid automatic repeated request (HARQ) information corresponding to the first PDSCH, and the second trigger message is configured to trigger the terminal to switch to the secondary component carrier to transmit second HARQ information corresponding to the second PDSCH;
- and
- receiving, on a first time domain resource of the secondary component carrier, the first HARQ information from the terminal, and receiving, on a second time domain resource of the secondary component carrier, the second HARQ information from the terminal, and
- wherein when a first moment of transmitting the first trigger message is earlier than a second moment of transmitting the second trigger message, the first time domain resource is earlier than the second time domain resource.
A physical downlink shared channel (PDSCH) receiving method, performed by a terminal, and comprising:
- receiving, on a primary component carrier, a first PDSCH, a second PDSCH, a first trigger message and a second trigger message from a base station, wherein the first trigger message is configured to trigger the terminal to switch to a secondary component carrier to transmit first hybrid automatic repeated request (HARQ) information corresponding to the first PDSCH, and the second trigger message is configured to trigger the terminal to switch to the secondary component carrier to transmit second HARQ information corresponding to the second PDSCH;
- and
- transmitting, on a first time domain resource of the secondary component carrier, the first HARQ information to the base station, and transmitting, on a second time domain resource of the secondary component carrier, the second HARQ information to the base station, wherein when a first moment of transmitting the first trigger message is earlier than a second moment of transmitting the second trigger message, the first time domain resource is earlier than the second time domain resource.
