說明書
This application is a continuation of PCT Application No. PCT/CN2018/072418, filed on Jan. 12, 2018 and titled with “methods and devices for information transmission”, the contents of which are hereby incorporated by reference in its entirety.
In a 5th-Generation (5G) system, Physical Uplink Control Channels (PUCCHs) of two lengths are supported, i.e., long PUCCHs and short PUCCHs. A terminal device may transmit different uplink information by use of different PUCCHs, for example, transmitting a Scheduling Request (SR) and feedback information (Acknowledgement (ACK) or Negative ACK (HACK)) through different PUCCHs. In such a case, how to transmit the SR and the feedback information more effectively becomes a problem urgent to be solved.
The application relates to the field of communications, and more particularly to a method and device for information transmission.
The embodiments of the application provide a method and device for information transmission, which may still effectively transmit different information under the condition that PUCCHs of two lengths exist.
A first aspect provides a method for information transmission, which may include that: control signaling which is transmitted by a network device is received by a terminal device at a first time position; and second information corresponding to the control signaling and/or first information are/is transmitted by the terminal device to the network device according to the first time position, a second time position for transmitting the first information being at least partially overlapped with a third time position for transmitting the second information.
