Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method, device, chip and module equipment. Background Art

[0002] In communication technology, network equipment can use time division duplex (TDD) communication mode. When using TDD communication mode, a time slot can be used for uplink transmission or downlink transmission. Generally, network equipment can configure TDD frame structure for terminal equipment so that terminal equipment can use time domain resources in TDD frame structure for data transmission. However, this single uplink and downlink time slot ratio may lead to large transmission delay and cannot meet more transmission requirements. Summary of the invention

[0003] The present application provides a communication method, device, chip and module equipment, which can reduce transmission delay and thus meet more transmission requirements.

[0004] In a first aspect, a communication method is provided, comprising: receiving configuration information from a network device, wherein the configuration information is used to determine a subband full duplex (SBFD) area within a period.

[0005] It can be seen that in the above embodiment, the terminal device can receive configuration information from the network, and the configuration information can be used to determine the SBFD area within the period, that is, the terminal device can obtain the time-frequency resources for uplink and / or downlink transmission. For example, a time slot can be used for both uplink transmission and downlink reception. In this way, the terminal device can perform both uplink transmission and downlink reception in the time slot, thereby reducing the transmission delay and meeting more transmission requirements.

[0006] Optionally, in combination with the first aspect, the configuration information is used to determine the SBFD area within the cycle, including: the configuration information is used to indicate a first non-SBFD area and a second non-SBFD area within the cycle; wherein the SBFD area is an area in the cycle excluding the first non-SBFD area and the second non-SBFD area.

[0007] It can be seen that in the above embodiment, the network device can indicate the first non-SBFD area and the second non-SBFD area within the period to the terminal device, so that the terminal device can determine the SBFD area based on the first non-SBFD area and the second non-SBFD area. That is, when the SBFD area is not explicitly indicated, the terminal device can deduce the SBFD area based on the first non-SBFD area and the second non-SBFD area, which is more flexible.

[0008] Optionally, in combination with the first aspect, the configuration information is used to indicate the first non-SBFD area within the cycle, including: the configuration information is used to indicate a first number and a second number; the first number is the number of consecutive first non-SBFD time units starting from the start position of the cycle, and the second number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups included in adjacent time units located after the consecutive first non-SBFD time units in the cycle; the first non-SBFD area is determined based on the first number and the second number; or, the configuration information is used to indicate a third number; the third number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups starting from the start position of the cycle; the first non-SBFD area is determined based on the third number.

[0009] It can be seen that in the above embodiment, the network device can indicate numbers, such as the first number and the second number, or the third number, so that the terminal device can determine the first non-SBFD area. In this way, signaling overhead can be saved.

[0010] Optionally, in combination with the first aspect, the configuration information is used to indicate the second non-SBFD area within the cycle, including: the configuration information is used to indicate a fourth number and a fifth number; the fourth number is the number of consecutive second non-SBFD time units starting from the end position of the cycle, and the fifth number is the number of consecutive non-SBFD time sub-units or consecutive non-SBFD time sub-unit groups included in adjacent time units located before the consecutive second non-SBFD time units in the cycle; the second non-SBFD area is determined based on the fourth number and the fifth number; or, the configuration information is used to indicate a sixth number; the sixth number is the number of consecutive non-SBFD time sub-units or consecutive non-SBFD time sub-unit groups starting from the end position of the cycle; the second non-SBFD area is determined based on the sixth number.

[0011] It can be seen that in the above embodiment, the network device can indicate numbers, such as the fourth number and the fifth number, or the sixth number, etc., so that the terminal device can determine the second non-SBFD area. In this way, signaling overhead can be saved.

[0013] It can be seen that in the above embodiment, the network device can indicate numbers, such as the seventh number and the eighth number, or the ninth number, etc., so that the terminal device can determine the SBFD area. In this way, signaling overhead can be saved.

[0014] Optionally, in combination with the first aspect, the configuration information is also used to indicate a tenth number, which is the number of non-SBFD time sub-units or non-SBFD time sub-unit groups included in the adjacent time units located after the first consecutive non-SBFD time units in the cycle, and the first consecutive non-SBFD time units start at the start position of the cycle. The eleventh number is determined based on the tenth number, and the eleventh number is the number of consecutive SBFD time sub-units or consecutive SBFD time sub-unit groups included in the adjacent time units located before the consecutive SBFD time units in the cycle; or, the configuration information is also used to indicate the eleventh number; wherein the SBFD area is determined based on the seventh number and the eighth number, including: the SBFD area is determined based on the seventh number, the eighth number and the eleventh number.

[0015] It can be seen that in the above embodiment, the network device can also indicate the tenth number so that the terminal device can determine the eleventh number, thereby indirectly determining the eleventh number based on the tenth number, which is more flexible. Alternatively, the network device can also indicate the eleventh number so that the terminal device can directly know the number of continuous SBFD time subunits or continuous SBFD time subunit groups included in the adjacent time unit located before the continuous SBFD time unit in the cycle, thereby reducing the calculation time inside the terminal device. In addition, since the terminal device can determine the SBFD area based on the seventh number, the eighth number and the eleventh number, it can save signaling overhead and make the determined SBFD area more accurate.

At least one symbol included in the second time slot is located at the beginning of the SBFD region.

[0109] Optionally, the number of first time units may be one or more.

The non-SBFD mentioned here may refer to uplink or downlink. If the types of all symbols included in a time slot are uplink, the time slot is located in the first non-SBFD area.

[0113] Optionally, the configuration information mentioned in any of the above methods 1 to 5 can be carried in cell-level signaling, such as system information blocks 1 (SIB1).

For example, a time slot can be used for both uplink transmission and downlink reception. In this way, the terminal device can perform both uplink transmission and downlink reception in the time slot, thereby reducing the transmission delay and meeting more transmission requirements.
