application example 1

[0484] In this application example, the terminal (that is, the second communication node) selects N transmission beam sets (that is, the N transmission mode sets) from the M transmission beam sets (that is, the transmission mode sets) to send the uplink control channel. Where M is a natural number, and N is a natural number less than or equal to M.

[0485] Such as image 3 As shown, the terminal has received the downlink data channel on {slotn1, slotn2, slotn3}, and / or the downlink measurement reference signal, and / or the terminal has received the channel quality report trigger control information, and the base station (the first communication node) Indicates that the ACK / NACK response control information for the downlink data channel and / or channel state information feedback needs to be sent on slotn4. When the transmission beam of the uplink control channel is obtained according to the transmission beam of the downlink control channel (or when the transmission beam of the...

application example 2

[0492] In this application example, the terminal (that is, the first communication node) selects N transmission beams from the M transmission beam sets (that is, the transmission mode set) to transmit the uplink control channel. Where M is a natural number, and N is a natural number less than or equal to M. The terminal selects the N transmission mode sets according to the time information corresponding to the M transmission modes and the type of signals related to the transmission modes

[0493] Such as image 3 As shown, the terminal receives the downlink data channel signal and / or the downlink measurement reference signal on {slotn1, slotn2, slotn3}, and the base station (that is, the second communication node) indicates the ACK / NACK response control for the downlink data channel information, and / or channel state information feedback needs to be sent on slotn4, when the transmit beam of the uplink control channel is obtained according to the transmit beam of the downlink c...

application example 3

[0497] In this application example, the terminal (that is, the first communication node) selects N transmission beams from the M transmission beam sets (that is, the transmission mode set) to transmit the uplink control channel. Where M is a natural number, and N is a natural number less than or equal to M. In this application example, the terminal selects the M sending beam sets as the N sending beam sets

[0498] Such as image 3 As shown, the terminal receives the downlink data channel signal and / or the downlink measurement reference signal on {slotn1, slotn2, slotn3}, and the base station (that is, the second communication node) indicates the ACK / NACK response control for the downlink data channel information, and / or channel state information feedback needs to be sent on slotn4, when the transmit beam of the uplink control channel is obtained according to the transmit beam of the downlink control channel (or when the transmit beam of the uplink control channel is obtained...

Abstract

The invention discloses a signal transmission method and system and a control information sending method and device. The signal sending method comprises: a first communication node acquires M sendingmode sets; the first communication node determines N sending mode sets for sending first signals among the M sending mode sets; the first communication node sends the first signals to the second communication node by using the N sending mode sets; wherein, one sending mode set comprises at least one sending mode, M is a natural number and N is a natural number smaller than or equal to M. The embodiments of the disclosure realize sending of high-frequency signals based on beam transmission in the NR technology.

Description

technical field [0001] The present disclosure relates to but not limited to communication technology, especially a method and system for transmitting signals and a method and device for sending control information. Background technique [0002] As one of the core technologies of NR (New Radio, new wireless), high-frequency transmission provides the possibility for future large-capacity and high-speed data transmission, but a core feature of high-frequency communication is large spatial fading and short transmission distance. The high-frequency wavelength is relatively short, and large-capacity MIMO ((Multiple-Input Multiple-Output, multiple-input multiple-output) can be used to form high-gain beams and increase transmission distance. However, because the beams cannot achieve omnidirectional coverage, there are Long Term Evolution, long-term evolution) has many different characteristics, and high-frequency communication based on beam transmission is a hot issue that NR is cur...
