Abstract
Disclosed in the present invention are a method and apparatus for transmitting uplink control information (UCI), solving the problem of UCI transmission in a short transmission time interval (TTI). The method comprises: a terminal determining a short transmission time interval (TTI) position and/or a short uplink channel for transmitting UCI; and the terminal transmitting the UCI on the determined short-TTI position and/or the short uplink channel, thereby providing a solution for transmitting periodic UCI in a short-TTI, and thus ensuring that the periodic UCI may be normally transmitted in the short-TTI.

A method for transmitting Uplink Control Information (UCI), the method comprising:
- determining, by a User Equipment (UE), a short-Transmission Time Interval (TTI) position and/or a short uplink channel for transmitting UCI;
- and
- transmitting, by the UE, the UCI in the determined short-TTI position and/or the determined short uplink channel;
- wherein determining, by the UE, the short-TTI position and/or the short uplink channel for transmitting UCI comprises:
- receiving, by the UE, second configuration information, wherein the second configuration information indicates a periodicity and an offset of a feedback short-TTI position for transmitting UCI, or indicates a periodicity of a feedback short-TTI position for transmitting UCI, and the periodicity and/or the offset are/is in the unit of a length of a short TTI, and determining, by the UE, the feedback short-TTI position according to the second configuration information;
- and
- transmitting, by the UE, the UCI in the determined short-TTI position and/or the determined short uplink channel comprises:
- transmitting, by the UE, the UCI in the feedback short-TTI position;
- wherein the UCI comprises at least one of Scheduling Request (SR) or Periodic Channel State Information (P-CSI).
A method for receiving Uplink Control Information (UCI), the method comprising:
- determining, by a base station, a short-Transmission Time Interval (TTI) position and/or a short uplink channel for transmitting UCI;
- and
- receiving, by the base station, the UCI in the determined short-TTI position and/or the determined short uplink channel;
- wherein determining, by the base station, the short-TTI position and/or the short uplink channel for transmitting UCI comprises:
- determining, by the base station, that the UCI is transmitted in a feedback short-TTI position;
- and
- after the base station determines the short-TTI position and/or the short uplink channel for transmitting UCI, the method further comprises:
- transmitting, by the base station, second configuration information to a UE, wherein the second configuration information indicates a periodicity and an offset of the feedback short-TTI position for transmitting UCI, or indicates a periodicity of a feedback short-TTI position for transmitting UCI, and the periodicity and/or the offset are/is in the unit of a length of a short TTI to a UE;
- wherein the UCI comprises at least one of Scheduling Request (SR) or Periodic Channel State Information (P-CSI).
A User Equipment (UE) comprising at least one processor and a memory;
- wherein the memory is configured to store readable program codes, and the at least one processor is configured to execute the readable program codes to:
- determine a short-Transmission Time Interval (TTI) position and/or a short uplink channel for transmitting Uplink Control Information (UCI);
- and
- transmit the UCI in the determined short-TTI position and/or the determined short uplink channel;
- wherein the at least one processor is configured to execute the readable program codes to:
- receive second configuration information, wherein the second configuration information indicates a periodicity and an offset of a feedback short-TTI position for transmitting UCI, or indicates a periodicity of a feedback short-TTI position for transmitting UCI, and the periodicity and/or the offset are/is in the unit of a length of a short TTI, and determine the feedback short-TTI position according to the second configuration information;
- and
- transmit the UCI in the feedback short-TTI position;
- wherein the UCI comprises at least one of Scheduling Request (SR) or Periodic Channel State Information (P-CSI).
A base station, comprising at least one processor and a memory;
- wherein the memory is configured to store readable program codes, and the at least one processor is configured to execute the readable program codes to:
- determine a short-Transmission Time Interval (TTI) position and/or a short uplink channel for transmitting UCI;
- and
- receive the UCI in the determined short-TTI position and/or the determined short uplink channel;
- wherein the at least one processor is configured to execute the readable program codes:
- to determine that the UCI is transmitted in a feedback short-TTI position;
- and
- to transmit second configuration information to a UE, wherein the second configuration information indicates a periodicity and an offset of the feedback short-TTI position for transmitting UCI, or indicates a periodicity of a feedback short-TTI position for transmitting UCI, and the periodicity and/or the offset are/is in the unit of a length of a short TTI;
- wherein the UCI comprises at least one of Scheduling Request (SR) or Periodic Channel State Information (P-CSI).
