[0145] Such as Figure 5 As shown, the embodiment of the present invention provides a method for sending indication information, including:

[0146] Step 51, determine a control channel according to predetermined time domain resources and frequency domain resources;

[0147] Specifically, firstly, a time domain resource is determined, in which the first time domain resource for bearing the control channel is determined; a frequency domain resource is determined, in which the frequency domain resource is determined for bearing the control channel first frequency domain resources;

[0148] Wherein, at least one minimum time-domain scheduling unit is determined as the time-domain resource; and at least one preset carrier is determined as the frequency-domain resource.

[0149] Step 52, sending indication information in the control channel, where the indication information is used to indicate the use of preset time-frequency resources before the control channel;

[0150] The co...

Abstract

The invention provides indication information sending and receiving methods, a base station and a terminal. The sending method comprises that a control channel is determined according pre-determined time-domain and frequency-domain resources; and the indication information used to indicate the using condition of the preset time-frequency resource before the control channel is sent in the control channel. The receiving method comprises that the indication information used to indicate the using condition of the preset time-frequency resource before the control channel is received in the controlchannel; and the using condition of the preset time-frequency resource before the control channel is determined according to the indication information. The problem that down channel quality measurement and down data demodulation performances are decreased during multi-service time division multiplexing is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending indication information, a method for receiving it, a base station and a terminal. Background technique [0002] In 5G system design, it is necessary to support a variety of services with their own distinct characteristics, including enhanced mobile Internet (eMBB, Enhance Mobile Broadband), ultra-high reliability and ultra-low latency communication (URLLC, UltraReliable&Low Latency Communication) and massive Networking communication (mMTC, Massive Machine Type Communication). [0003] eMBB has corresponding requirements on peak rate and user experience rate, but may not be sensitive to delay. URLLC services require ultra-high transmission reliability and lower-latency data transmission, which may require a shorter transmission time interval TTI in the time domain than eMBB services to achieve fast scheduling and transmission. [0004] The 5G ...
