Communication method and base station

A base station, comprising:

• a processor;
• and
• a memory storing a plurality of instructions, which when executed by the processor, causes the processor to:
• determine a time length of a time domain scheduling unit, and determine which symbols are occupied by a downlink, a guard period and an uplink in the time domain scheduling unit, wherein the time length of the time domain scheduling unit is 2n*5m ms, the n and m in 2n*5m being integers, when the time domain scheduling unit comprises one subframe and the subframe comprises 14 symbols:
• when information transmitted by the time domain scheduling unit merely comprises uplink information, the number of the symbols occupied by the downlink is set to be zero, the number of the symbols occupied by the guard period is set to be zero, and the number of the symbols occupied by the uplink is set to be 14;
• when the information transmitted by the time domain scheduling unit comprises Downlink Control Information (DCI) and/or downlink reference information of a Physical Downlink Control Channel (PDCCH), and uplink data and/or Uplink Control Information (UCI) and/or a Sounding Reference Signal (SRS) and/or a Random Access Preamble (RA preamble), the number of the symbols occupied by the downlink is set to be 1 or 2 or 3, the number of the symbols occupied by the guard period is set to be 1 or 2, and remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit includes DCI of the PDCCH and/or downlink data of a Physical Downlink Shared Channel (PDSCH) and/or Downlink Reference Information (DRI), and the uplink data and/or the UCI and/or the SRS and/or the RA preamble, the number of the symbols occupied by the downlink is set to be 12, the number of the symbols occupied by the guard period is set to be 1, and the remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit includes DCI of an enhanced Physical Downlink Control Channel (ePDCCH) and/or downlink data and/or DRI of a PDSCH, and uplink data and/or the UCI and/or the SRS and/or the RA preamble, the number of the symbols occupied by the downlink is set to be 7, the number of the symbols occupied by the guard period is set to be 1 or 2, and the remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit merely comprises the downlink information, the number of the symbols occupied by the downlink is set to be 14, the number of the symbols occupied by the guard period is set to be zero, and the number of the symbols occupied by the uplink is set to be zero;
• generate length configuration information of the time domain scheduling unit according to the time length of the time domain scheduling unit, and the symbols occupied by the downlink, the guard period and the symbols the uplink comprised in the time domain scheduling unit;
• send the length configuration information to a terminal through radio resource control signaling and/or downlink control information signaling, and inform the terminal of a length configuration of the time domain scheduling unit;
• implement a communication with the terminal by the base station based on the length configuration of the time domain scheduling unit, after the terminal acquires the length configuration of the time domain scheduling unit.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor of a base station, causes the processor of the base station to perform a communication method, the communication method comprising:

• determining, by a base station, a time length of a time domain scheduling unit, and determining which symbols are occupied by a downlink, a guard period and an uplink in the time domain scheduling unit, wherein the time length of the time domain scheduling unit is 2n*5m ms, the n and m in 2n*5m being integers, when the time domain scheduling unit comprises one subframe and the subframe comprises 14 symbols:
• when information transmitted by the time domain scheduling unit merely comprises uplink information, the number of the symbols occupied by the downlink is set to be zero, the number of the symbols occupied by the guard period is set to be zero, and the number of the symbols occupied by the uplink is set to be 14;
• when the information transmitted by the time domain scheduling unit comprises Downlink Control Information (DCI) and/or downlink reference information of a Physical Downlink Control Channel (PDCCH), and uplink data and/or Uplink Control Information (UCI) and/or a Sounding Reference Signal (SRS) and/or a Random Access Preamble (RA preamble), the number of the symbols occupied by the downlink is set to be 1 or 2 or 3, the number of the symbols occupied by the guard period is set to be 1 or 2, and remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit includes DCI of the PDCCH and/or downlink data of a Physical Downlink Shared Channel (PDSCH) and/or Downlink Reference Information (DRI), and the uplink data and/or the UCI and/or the SRS and/or the RA preamble, the number of the symbols occupied by the downlink is set to be 12, the number of the symbols occupied by the guard period is set to be 1, and the remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit includes DCI of an enhanced Physical Downlink Control Channel (ePDCCH) and/or downlink data and/or DRI of a PDSCH, and uplink data and/or the UCI and/or the SRS and/or the RA preamble, the number of the symbols occupied by the downlink is set to be 7, the number of the symbols occupied by the guard period is set to be 1 or 2, and the remaining symbols are set to be the length of the uplink;
• when the information transmitted by the time domain scheduling unit merely comprises the downlink information, the number of the symbols occupied by the downlink is set to be 14, the number of the symbols occupied by the guard period is set to be zero, and the number of the symbols occupied by the uplink is set to be zero;
• generating length configuration information of the time domain scheduling unit according to the time length of the time domain scheduling unit, and the symbols occupied by the downlink, the guard period and the symbols the uplink comprised in the time domain scheduling unit;
• sending the length configuration information to a terminal through radio resource control signaling and/or downlink control information signaling, and informing the terminal of a length configuration of the time domain scheduling unit;
