Embodiment 1

[0093] Embodiment 1: The terminal determines the target code rate r max =1 / 2, the number of uplink control signaling bits to be transmitted is N=8. The number of pre-configured resources is 2 PRBs (each PRB includes 12 carriers). The terminal uses the 2-symbol PUCCH to transmit uplink control information (that is, occupies 2 time-domain symbols), wherein the reference signal overhead contained in the PUCCH is 1 / 3, and the PUCCH is modulated by QPSK, and the corresponding modulation order Q=2.

[0094] The terminal determines that the first resource quantity is where N UCI_RE is the number of REs occupied by UCI in one PRB.

[0095] The first resource quantity is smaller than the preconfigured resource quantity, and the terminal determines to use 1 PRB to transmit the uplink control information.

Embodiment 2

[0096] Embodiment 2: The terminal determines the target code rate r max =1 / 8, the number of uplink control signaling bits to be transmitted is N=10. The number of pre-configured resources is 2 PRBs (each PRB includes 12 carriers). The terminal uses the 2-symbol PUCCH to transmit uplink control information (that is, occupies 2 time-domain symbols), wherein the reference signal overhead contained in the PUCCH is 1 / 3, and the PUCCH is modulated by QPSK, and the corresponding modulation order Q=2.

[0097] The terminal determines that the first resource quantity is where N UCI_RE is the number of REs occupied by UCI in one PRB.

[0098] The first number of resources is greater than the number of pre-configured resources, and the terminal determines that the number of bits of the first uplink control signaling is where N configured The number of resources provisioned for.

[0099] The terminal compresses the bits of the uplink control signaling to be transmitted to obtain n...

Embodiment 3

[0100] Embodiment 3: On the basis of Embodiment 2, if due to the limitation of the UCI compression method, the terminal determines that the number of uplink control signaling bits actually transmitted is If T=4.

[0101] The terminal further determines the amount of resources actually needed to transmit the 4-bit uplink control information

[0102] The terminal determines to use one PRB to transmit the 4-bit compressed uplink control information.

[0103] The second embodiment of the present invention relates to a method for determining uplink control channel resources.

[0104] The first embodiment is a method for determining uplink control channel resources on the terminal side, and the second embodiment is a method for determining uplink control channel resources on the network side. The technical concepts of the two are the same, but the implementation positions are different, and the relevant details can be exchanged. use. figure 2 It is a schematic flowchart of th...

Abstract

The invention relates to the field of wireless communication, and discloses an uplink control channel resource determination method, a terminal and network side equipment. When a value range of the size of the actually transmitted uplink control signaling is very large, the problem of how to effectively prevent the waste of time-frequency resources is solved. According to the invention, the terminal determines the number N of uplink control signaling bits to be transmitted; the terminal determines a first resource quantity according to the target coding rate and N; the terminal determines thequantity of actually used resources according to the first resource quantity and the quantity of pre-configured resources; and the terminal transmits the uplink control signaling by using the actuallyused resource quantity.

Description

[0001] This application is a divisional application of an application with an application date of November 07, 2018, an application number of 2018800341731, and an invention titled "Method for Determining Uplink Control Channel Resources, Terminal, and Network Side Equipment". technical field [0002] The present application relates to the field of wireless communication, in particular to the technology for determining uplink control channel resources. Background technique [0003] In order to ensure the demodulation performance of the uplink control channel in the 5G NR system, the network device may configure the maximum coding rate of the uplink control signaling that it can carry for different terminals (the lower the coding rate, the larger the uplink coverage radius, and the terminal sends The lower the probability of power limitation). [0004] In addition, the NR determines the resource base station corresponding to the uplink control channel for transmitting the fee...
