Description

Method, device, terminal and network side equipment for determining size of transmission resource
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for determining a size of a transmission resource.
Background
In a 5G NR (New Radio, New air interface) system, when a PUCCH (Physical Uplink Control CHannel) and a PUSCH (Physical Uplink Shared CHannel) overlap in resources, a UCI (Uplink Control Information) is multiplexed on the PUSCH overlapping with the PUCCH under a condition that a time limit is satisfied for transmission.
In the 5G NR system, URLLC (Ultra-Reliable and Low Latency Communications) service has requirements of Low Latency and high reliability. To improve PUSCH transmission reliability and reduce latency, PUSCH enhancements in NRs will support single or multiple short slot or slotted PUSCH repetition transmissions, with each short slot (mini-slot) PUSCH allowed to cross slot boundaries or uplink and downlink switching points. If a certain PUSCH repeatedly crosses a slot boundary or an uplink and downlink switching point, the PUSCH (which may be referred to as a nominal PUSCH) is divided into two or more PUSCHs (which may be referred to as actual PUSCHs) for transmission. When the PUCCH overlaps with a resource of a divided actual PUSCH, UCI is multiplexed and transmitted on the actual PUSCH under the condition that a predetermined time limit is satisfied. However, since the actual PUSCH actual length is smaller than the length of the PUSCH time domain resource allocation indication, the UCI actual transmission resource is reduced and the transmission reliability is affected according to the existing UCI resource calculation method.
