Abstract

An uplink control information transmission method and an apparatus. The method includes determining, by a terminal device, according hybrid automatic repeat request-acknowledgment (HARQ-ACK) information and a mapping relationship, a channel resource corresponding to the HARQ-ACK information, where a channel resource corresponding to an acknowledgement (ACK) and a channel resource corresponding to {ACK, negative acknowledgement (NACK)} in the mapping relationship are the same, generating, by the terminal device, an uplink signal based on the channel resource corresponding to the HARQ-ACK information, and sending, by the terminal device, the uplink signal.

Claims20

Dependent claims

An uplink control information transmission method, comprising:

determining, by a terminal device, according to hybrid automatic repeat request-acknowledgment (HARQ-ACK) information and a mapping relationship, a channel resource corresponding to the HARQ-ACK information, wherein a channel resource corresponding to an acknowledgement (ACK) and a channel resource corresponding to {ACK, negative acknowledgement (NACK)} in the mapping relationship are the same, wherein the ACK is associated with the terminal device detecting one physical downlink control channel (PDCCH) of a first PDCCH and a second PDCCH sent by a network device, and is further associated with the terminal device not detecting another one of the first PDCCH and the second PDCCH, and wherein the {ACK, NACK} is associated with the terminal device detecting both the first PDCCH and the second PDCCH;
generating, by the terminal device, an uplink signal based on the channel resource corresponding to the HARQ-ACK information;
and
sending, by the terminal device, the uplink signal.

1 more element

An uplink control information transmission method, comprising:

receiving, by a network device, an uplink signal;
and
determining, by the network device according to a channel resource for the uplink signal, a quantity of hybrid automatic repeat request-acknowledgment (HARQ-ACK) information bits and a mapping relationship, wherein HARQ-ACK information corresponds to the channel resource for the uplink signal, and wherein a channel resource corresponding to an acknowledgement (ACK) and a channel resource corresponding to {ACK, negative acknowledgement (NACK)} in the mapping relationship are the same, wherein the ACK is associated with a terminal device detecting one physical downlink control channel (PDCCH) of a first PDCCH and a second PDCCH sent by the network device, and is further associated with the terminal device not detecting another one of the first PDCCH and the second PDCCH, and wherein the {ACK, NACK} is associated with the terminal device detecting both the first PDCCH and the second PDCCH.

A communications device, comprising:

a transmitter;
a processor;
and
a non-transitory computer readable medium comprising a program stored thereon for execution by the processor, the program including instructions to:
determine, according to hybrid automatic repeat request-acknowledgment (HARQ-ACK) information and a mapping relationship, a channel resource corresponding to the HARQ-ACK information, wherein a channel resource corresponding to an acknowledgement (ACK) and a channel resource corresponding to {ACK, negative acknowledgement (NACK)} in the mapping relationship are the same, wherein the ACK is associated with the communications device detecting one physical downlink control channel (PDCCH) of a first PDCCH and a second PDCCH sent by a network device, and is further associated with the communications device not detecting another one of the first PDCCH and the second PDCCH, and wherein the {ACK, NACK} is associated with the communications device detecting both the first PDCCH and the second PDCCH;
generate an uplink signal based on the channel resource corresponding to the HARQ-ACK information;
and
cause the transmitter to send the uplink signal.
