Response processing method and apparatus, response configuration method and apparatus, information transmission method and apparatus, terminal and base station

Abstract

The invention provides a response processing method and apparatus, a response configuration method and apparatus, an information transmission method and apparatus, a terminal and a base station. The response processing method comprises the following steps: a receiving terminal detects physical layer control information; the receiving terminal determines whether to respond to a sending terminal according to predetermined information or the configuration signaling of the base station; and when the judgment result is yes, the receiving terminal sends physical layer response signaling to the sending terminal. By adoption of the invention, the problem of control information loss in the high-frequency communication based on beam transmission in related art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a response processing, response configuration, information transmission method, device, terminal and base station. Background technique [0002] In a wireless communication system, the transmitting end and the receiving end generally use multiple antennas to transmit and receive to obtain a higher rate. One principle of multi-antenna technology is to use some characteristics of the channel to form a transmission that matches the characteristics of the channel. The radiation direction of the signal is very targeted, which can effectively improve system performance and obtain significant performance without increasing bandwidth and power. Boosting, is a very promising technique that is widely used in current systems. With the development of multi-antenna technology, it is a trend to use beamforming (Beamforming) technology to enhance the coverage of various channel signals, espe...

Problems solved by technology

[0008] Another example is that the base station will perform uplink power control through DCI. When this information is not received, the base station will think that the terminal has adjusted the transmit power, but in fact the terminal has not adjusted. There will be problems in the transmission judgment, and there may be wrong uplink scheduling, MCS judgment and layer judgment;

[0009] (2) When the transmission link is broken in the system, the location and degree of the link cannot be accurately judged; when the transmission problem occurs at the sending end, it cannot accurately judge whether it is a problem with the control channel or a problem with the data channel, nor can it be accurately It is judged whether there is an uplink problem, a downlink problem, or all problems;

[0010] For example, in one case, the base station triggers the terminal to transmit uplink data, but the base station does not receive the uplink transmission data. At this time, there may be a problem with the downlink control channel, or there may be a problem with the uplink data channel. , but the base station does not know exactly where the problem occurs;

[0011] Another situation is that the base station performs downlink transmission, but does not receive the terminal feedback acknowledgment (Acknowledgment, referred to as ACK) / non-acknowledgment information (Negative ACKnowledgment, referred to as NACK), at this time the base station does not know that it is a downlink control channel. The authorization information is not detected correctly, or there is a problem when the ACK / NACK is fed back on the uplink control channel, both of which will cause the base station to fail to receive the ACK / NACK information;

[0012] In addition, there are some similar situations. For example, the base station triggers the uplink CSI feedback but does not receive it. At this time, the base station does not know whether the downlink trigger signaling is not received by the terminal, or it is due to the uplink CSI feedback. For another example, the terminal sent a Scheduling Request (SR for short) request, but did not receive the scheduling information, and the terminal did not know whether there was a problem when the SR request was sent or the failure to receive was caused by the loss of the downlink control channel link. to schedule information
