Description

Method for transmitting uplink control information, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a terminal device, and a network device for transmitting uplink control information.

Background

Future communication systems, such as 5G systems (or called 5G NR (new radio) systems), support technologies such as dynamically determining a Hybrid Automatic Repeat reQuest (HARQ) timing, a flexible subframe structure, carrier aggregation, and a large-scale antenna, and the introduction of these technologies may cause a large difference in the number of bits of uplink control information transmitted by a terminal device in different time units (e.g., different time slots).

The existing protocol defines multiple uplink control channel formats (formats), and different uplink control channel formats have different uplink control information capacities to support transmission of uplink control information with different capacities. When the terminal equipment is actually used, the terminal equipment selects an uplink control channel format matched with the capacity of the uplink control information to be transmitted from a plurality of predefined uplink control channel formats, and transmits the uplink control information based on the uplink control channel format.

The transmission mode of the uplink control information of the existing protocol is not flexible enough and is not suitable for a communication system with larger bit number difference of the uplink control information.

In particular, if a large number of uplink control channel formats are defined, it is inevitable to make the protocol too complicated, and if only a small number of uplink control channel formats with large capacity are defined, it is inevitable to waste uplink transmission resources.

An embodiment of the present invention provides a method for transmitting uplink control information, which can support flexible extension of transmission resources of the uplink control information, and is described in detail below with reference to fig. 1.

Specifically, the time unit may be defined in various ways, for example, the time unit may be a time slot. Taking time unit as a time slot and the multiple uplink control channel units as 3 uplink channel units as an example, the target time unit may be time slot n +1 in fig. 2a, where the 3 uplink channel units are located in the uplink region of time slot n +1, and the 3 uplink channel units carry the target uplink control information that needs to be transmitted in time slot n + 1.

For example, the uplink control channel element may correspond to a small-capacity uplink control channel format, and the terminal device may flexibly expand the transmission resource of the uplink control information in units of the uplink control channel element according to actual needs, thereby improving the flexibility of uplink control information transmission.

Optionally, in some embodiments, the terminal device determines the numbers of the resources occupied by the other uplink control channel units according to the number of the resources occupied by the first uplink control channel unit and a predefined function. For example, the predefined function is x + i, where x represents the number of the resource occupied by the first uplink control channel unit, and i represents the ith uplink control channel unit in other uplink control channel units, and the number of the resource occupied by the first uplink control channel unit can be determined by substituting the function with the number of the resource occupied by the first uplink control channel unit.

For example, the number of resources occupied by other uplink control channel elements may be the sum, difference or any other combination of the number of resources occupied by the first uplink control channel element and the number of TBs or coding blocks carried in other downlink data.

For example, the terminal device calculates the number of the first uplink control channel unit according to the number of the physical resource occupied by the downlink control channel by a predefined operation rule, and then determines the resource occupied by the first uplink control channel unit based on the number of the first uplink control channel unit.

The terminal equipment receives DCI, the DCI schedules the terminal to receive PDSCH, and the DCI further indicates the resource position (time domain position, frequency domain position, code domain sequence index) of the uplink control channel unit for transmitting ACK/NACK corresponding to the current PDSCH.

Scene two: the terminal equipment firstly determines the size of the resource occupied by the uplink control channel unit; the terminal equipment determines the maximum bit number N of uplink control information which can be transmitted by an uplink control channel unit and determines the bit number of target uplink control information to be transmitted; terminal equipment is according toAnd determining the number of uplink control channel units required by the target uplink control information.

Specifically, the terminal device determines that the length of the time domain resource occupied by the uplink control channel unit is 1 OFDM symbol, and the length of the frequency domain resource is the frequency domain resource length corresponding to 1 RB, such as 12 subcarriers. Assuming that one uplink control channel unit carries 2 bits of information at most, if the terminal needs to feed back 10 bits of CSI in the target time slot, the terminal equipment determines to use 5 uplink control channel units to transmit the 10 bits of CSI, and if the terminal needs to feed back 15 bits of CSI in the target time slot, the terminal determines to use 8 uplink control channel units to transmit the 15 bits of CSI.
