Problems solved by technology
[0003] When the UE receives downlink data from two network nodes, it needs to send the feedback information of the hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request) of the downlink data to the two network nodes at the same time, that is, the correct response (ACK, Acknowledgment ) or an error response (NACK, Non-Acknowledgment), or need to send HARQ feedback information and data carried by the Physical Uplink Share Channel (PUSCH, Physical Uplink Share Channel) to two network nodes at the same time, but the time in the same subframe The domain symbol can only carry the data of one network node, so the UE cannot send uplink data to two network nodes at the same time

Embodiment Construction
[0161] An embodiment of the present invention provides a method for information configuration, which can send at least one piece of HARQ feedback information through part of the time domain symbols in the same subframe, so that UEs capable of dual-chain reception and single-chain transmission can send Different network nodes send HARQ feedback information, which also improves the utilization rate of time-domain symbols and speeds up the sending speed of HARQ feedback information. Embodiments of the present invention also provide corresponding equipment and systems. Each will be described in detail below.
[0162] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other e...

The invention discloses a method for configuring information, includes receiving a configuration signaling sent by a network node, wherein the configuration signaling is used for instructing a terminal to send at least one hybrid automatic retransmission request HARQ feedback information, and a part of time domain symbols occupied by each HARQ feedback information in the at least one HARQ feedbackinformation in the same subframe when the terminal sends at least one hybrid automatic retransmission request HARQ feedback information; Configuring the at least one HARQ feedback information on a part of time domain symbols in the same subframe occupied by each HARQ feedback information; Sending the configured at least one HARQ feedback information to the network node. The technical proposal provided by the embodiment of the invention can send at least one HARQ feedback information through a part of time domain symbols in the same subframe, so that the UE with the double-link receiving capacity and the single-chain transmitting capacity can send the HARQ feedback information to different network nodes at the same time.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an information configuration method, device and system. Background technique [0002] There is a type of user equipment (UE, User Equipment) in the communication system. This type of UE has dual-link receiving capability, that is, it can receive downlink data from two network nodes at the same time, but only has single-link transmitting capability, that is, it can only transmit Send uplink data to different network nodes at different times. [0003] When the UE receives downlink data from two network nodes, it needs to send the feedback information of the hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request) of the downlink data to the two network nodes at the same time, that is, the correct response (ACK, Acknowledgment ) or an error response (NACK, Non-Acknowledgment), or need to send HARQ feedback information and data carried by the Physical U...
