Abstract
Embodiments of the present invention provide a hybrid automatic repeat request-acknowledgment transmission method and an apparatus. The hybrid automatic repeat request-acknowledgment transmission method includes: receiving, by user equipment, on a first serving cell in a subframe n-k, a PDSCH or a downlink control channel indicating downlink SPS release; and sending, by the user equipment in a subframe n, an HARQ-ACK corresponding to the PDSCH or the downlink control channel that is of the first serving cell and that is in the subframe n-k, where an HARQ-ACK timing includes a first HARQ-ACK timing or a second HARQ-ACK timing.
Claims18
A n method, comprising:
- receiving, by user equipment, on a first serving cell in a subframe n-k, a physical downlink shared channel (PDSCH) or a downlink control channel indicating downlink semi-persistent scheduling (SPS) release, wherein the first serving cell is a serving cell of the user equipment;
- and
- sending, by the user equipment in a subframe n, a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to the PDSCH or the downlink control channel that is of the first serving cell and that is in the subframe n-k, wherein n is an integer, k is a positive integer, k belongs to a set K, the set K is determined according to a configured HARQ-ACK timing, and the configured HARQ-ACK timing comprises a first HARQ-ACK timing or a second HARQ-ACK timing.
A method, comprising:
- sending, by a base station to a user equipment, on a first serving cell in a subframe n-k, a physical downlink shared channel (PDSCH) or a downlink control channel indicating downlink semi-persistent scheduling (SPS) release, wherein the first serving cell is a serving cell of the user equipment;
- and
- receiving, by the base station in a subframe n, a hybrid automatic repeat request-acknowledgment (HARQ-ACK) that is sent by the user equipment and that corresponds to the PDSCH or the downlink control channel that is of the first serving cell and that is in the subframe n-k, wherein n is an integer, k is a positive integer, k belongs to a set K, and the set K is determined according to a HARQ-ACK timing configured by the base station for the user equipment, and the configured HARQ-ACK timing comprises a first HARQ-ACK timing or a second HARQ-ACK timing.
User equipment, comprising:
- a receiver, configured to receive, on a first serving cell in a subframe n-k, a physical downlink shared channel (PDSCH) or a downlink control channel indicating downlink semi-persistent scheduling (SPS) release, wherein the first serving cell is a serving cell of the user equipment;
- and
- a transmitter, configured to send, in a subframe n, a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to the PDSCH or the downlink control channel that is of the first serving cell and that is in the subframe n-k, wherein n is an integer, k is a positive integer, k belongs to a set K, the set K is determined according to a configured HARQ-ACK timing, and the configured HARQ-ACK timing comprises a first HARQ-ACK timing or a second HARQ-ACK timing.
A base station, comprising:
- a processor;
- and
- a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- configuring a hybrid automatic repeat request-acknowledgment (HARQ-ACK) timing for a user equipment, wherein the HARQ-ACK timing comprises a first HARQ-ACK timing or a second HARQ-ACK timing;
- a transmitter, configured to send, to the user equipment, on a first serving cell in a subframe n-k, a physical downlink shared channel (PDSCH) or a downlink control channel indicating downlink semi-persistent scheduling (SPS) release, wherein the first serving cell is a serving cell of the user equipment;
- and
- a receiver, configured to receive, in a subframe n, an HARQ-ACK that is sent by the user equipment and that corresponds to the PDSCH or the downlink control channel that is of the first serving cell and that is in the subframe n-k, wherein n is an integer, k is a positive integer, k belongs to a set K, and the set K is determined according to the HARQ-ACK timing configured for the user equipment.
