Embodiment approach

[0036] Way 1: The indicator includes a value coefficient of the second resource, and the terminal device calculates the quantity value of the second resource through the value coefficient, that is, determines the quantity of resource units included in the second resource.

[0037] The value coefficient includes two cases corresponding to N=0 and N>0. If N>0, the terminal device can determine the specific value of N according to the preset value coefficient β.

[0038] Alternatively, the value coefficient in the indicator corresponds to the value of the variable β, and the terminal device calculates the first parameter according to the value of β, the number of bits of the uplink control information, and the configuration information about the scheduling-free PUSCH in the scheduling-free resource configuration information. The quantity value corresponding to the second resource is N. The value of the variable β includes the case where it is equal to 0. For example

Abstract

A mobile communication uplink information transmission method and system, aiming to solve the problem that the transmission performance of the uplink shared channel is affected by the amount of resources occupied by uplink control information when terminal equipment allocates uplink control information and uplink shared channels on semi-statically configured physical uplink shared channels The problem. The method is used for a terminal device to send uplink information and a network device to receive uplink information, the terminal device receives scheduling-free resource configuration information, and determines that the first resource is used to allocate a physical uplink shared channel; the scheduling-free resource configuration information also includes instructions The indicator is used to determine a second resource, and the second resource is used to allocate uplink control information; the second resource is a part of the first resource. The terminal device further determines a third resource, which is used to allocate an uplink shared channel; the third resource is a part of the first resource and is disjoint with the second resource, or the second resource is empty. The invention also provides a system for said method.

Description

technical field [0001] The present application relates to the communication field, in particular to a kind of mobile communication uplink information transmission. Background technique [0002] In the new radio communication (NR) technology and the LTE technology, the terminal device reports uplink control information (UCI) to the network device, which is used as a basis for the network device to schedule the data transmission of the terminal device. Generally, a terminal device sends uplink control information on a physical uplink control channel (PUCCH); when the terminal device works on a physical uplink shared channel (PUSCH), it can also be used to send uplink control information. [0003] There are two types of PUSCH configuration methods, the first is that the network device sends downlink control information (DCI) to schedule the PUSCH sent by the terminal device, and the second is that the network device semi-statically configures the PUSCH sent by the terminal devi...
