Description
Technical Field
The invention relates to the technical field of communication, in particular to control information sending methods and sending devices, control information receiving methods and receiving devices and communication equipment.
Background
According to future application requirements, the 5G system needs to support multiple service scenes, wherein the communication scenes of Low-delay and high-reliability (Ultra-reliable and Low-Latency Communications, URLLC) such as unmanned driving, industrial automation and the like are concerned extensively . under the normal condition, URLLC data has extremely high burstiness and has higher requirement on delay, so that the data has extremely high resource scheduling priority.
Based on the current data scheduling manner, the base station needs to configure a corresponding Physical Downlink Control Channel (PDCCH) to indicate the relevant Information (time-frequency position, Redundancy version, number of hybrid automatic repeat request processes, uplink power Control Information, etc.) of the URLLC data sent this time when scheduling the URLLC data each time, besides, the PDCCH also contains some necessary common Control Information including system messages, currently, the transmission and sending manner of the PDCCH of the URLLC service is similar to that of LTE (Long Term Evolution), that is, the URLLC terminal needs to perform blind detection on the PDCCH before receiving data, because the PDCCH is temporarily configured and sent by the base station according to data scheduling needs, the URLLC terminal has not received other Information except for system Information acquired during access, therefore, the terminal does not know the number, position, and DCI (Downlink Control Channel) unit (PDCCH) occupied by the PDCCH, and the number, position, and DCI (Downlink Control Information) transmitted by the terminal are more than system Information, and therefore, the terminal does not know that the PDCCH belongs to the number, the DCI Information of the PDCCH is needed by a plurality of Downlink Control Channel units (Downlink Control Channel) and the PDCCH aggregation Control Information (DCI) and the terminal is capable of acquiring the Downlink Information, and the DCI Information of Downlink Information (Downlink Information) of the PDCCH aggregation Control Information, if the PDCCH aggregation Control Information is needed by a Downlink Control Information (PDCCH aggregation Control Information) and the terminal is detected successfully, the Downlink Control Information (DCI) of a Downlink Control Information (Downlink transport Downlink aggregation Control Channel) of a Downlink transport Downlink aggregation Control Channel (Downlink transport Downlink aggregation Downlink transport Downlink subframe) and a Downlink subframe) of a Downlink subframe) and a Downlink subframe) of a Downlink subframe).
From the above analysis, it can be seen that, due to uncertainty in the format, aggregation level, location, and the like of the control message during scheduling, the terminal needs to spend a lot of time and power to perform blind detection on the control message (currently, the number of blind detections for PDCCHs can be up to 44 times), and for the URLLC terminal, the time delay and power consumption are unacceptable, so it is necessary to improve PDCCH configuration and transmission and reception modes to reduce the processing time of the URLLC terminal when receiving the demodulated PDCCH.
