Embodiment 1

[0108] The method embodiment provided in Embodiment 1 of the present application may be executed in a base station, a user equipment, a mobile terminal, a computer terminal, or a similar computing device. Taking running on the base station as an example, image 3 It is a block diagram of the hardware structure of the base station of the uplink control receiving method according to the embodiment of the present invention. Such as image 3 As shown, the base station 30 may include one or more (only one is shown in the figure) processors 32 (the processors 32 may include but not limited to processing devices such as microprocessor MCU or programmable logic device FPGA, etc.), for storing A memory 34 for data, and a transmission device 36 for communication functions. Those of ordinary skill in the art can understand that, image 3 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, base statio...

example 1

[0188] When there are PUCCHs of UEs with different beam directions in the slot, the transmitter places the PUCCHs of UEs with different beam directions according to OFDM symbols, and places the OFDM symbols of PUCCHs of UEs with different beam directions according to the following rules:

[0189] When the PUCCH of a UE with a different beam direction has the same beam direction as the uplink data transmission in the slot, the transmitting end will place the PUCCH of the UE (for example, UE1) with the same beam direction as the uplink data transmission in the slot next to the transmission In the OFDM symbols of the uplink data (here, the adjacent OFDM symbols refer to the OFDM symbols for transmitting uplink data and the OFDM symbols for transmitting uplink control, the same below). Specifically, corresponding to figure 1 , 2 , when the uplink control is placed at the end of the slot, the PUCCH of UE1 is placed in the OFDM symbol next to the OFDM symbol that transmits uplink d...

[0193] When there are PUCCHs of UEs with different beam directions in the slot, the transmitter places the PUCCHs of UEs with different beam directions according to OFDM symbols, and places the OFDM symbols of PUCCHs of UEs with different beam directions according to the following rules:

[0194] When there is at least one beam direction in the PUCCH of the UE with different beam directions that is the same as the beam direction of the data transmitted in the slot, the transmitting end carries and transmits in the PUCCH in the symbol immediately before or after the symbol that transmits uplink data in the slot At least one UCI with the same beam direction among the beam directions of the uplink data.

[0195] or,

[0196] When the PUCCHs of multiple UEs are located in different OFDM symbols in the slot, the base station places the PUCCHs of the UEs that are at least one of the same beam directions as the uplink data transmission in the slot in the OFDM symbols next to the upli...

Abstract

The invention provides an uplink control receiving method and device, an uplink control transmitting method and device, a base station and user equipment. The uplink control receiving method comprisesthe following steps: configuring or agreeing orthogonal frequency division multiplexing (OFDM) symbols for transmitting uplink control for receiving ends respectively in a transmission unit, whereinthe position of the OFDM symbol where the uplink control of the same receiving end is located in the transmission unit and the position of an OFDM symbol where uplink data are located in the transmission unit remain continuous; and receiving the uplink control in the configured or agreed OFDM symbols. Through adoption of the uplink control receiving method and device, the uplink control transmitting method and device, the base station and the user equipment, the problem of processing complexity in the configuration way of the OFDM symbol positions in the uplink control of the receiving ends inthe prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for receiving and sending uplink control, a base station and user equipment. Background technique [0002] A new generation mobile communication system (New Radio, NR for short) is being researched and standardized, which is also one of the priorities of the current 3rd Generation Partnership Project (3GPP for short). [0003] Among the NR systems that can be determined at present, there will be three typical service types in the future. Common services include: enhanced Mobile Broadband (eMBB for short), Ultra-Reliable and Low Latency Communications (URLLC for short), and massive MachineType Communications (mMTC for short) . These services have different requirements on delay, coverage and reliability. For example, for eMBB, high peak transmission rate is mainly emphasized, the requirement for delay is not high (there is no requirement for low delay), an...
