Description

Data transmission method, apparatus, processor readable storage medium and computer program product Technical Field The present disclosure relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, processor readable storage medium, and computer program product. Background In a wireless communication system, in order to measure adjacent frequencies, a Measurement Gap (Measurement Gap) is introduced. During the measurement gap, the terminal pauses the operations of data receiving and data transmitting on the current fuwu Frequency points, and adjusts a Radio Frequency (RF) part to a target Frequency point for signal measurement. The terminal will typically use specific measurement algorithms and hardware circuitry to accomplish these measurement tasks. For example, in long term evolution (Long Term Evolution, LTE) and fifth generation mobile communication technology (5 th-Generation Mobile Communication Technology, 5G) New air interface (NR) systems, the terminal may measure reference signals of other frequency points, such as cell specific reference signals (CELL REFERENCE SIGNAL, CRS) in LTE, synchronization signal blocks (Synchronization Signal Block, SSB) in 5G NR, and the like, according to parameters such as measurement period and measurement bandwidth configured by the network. In the measurement gap, the terminal pauses operations such as data receiving and transmitting on the current service frequency point, so that transmission of uplink data and downlink data can be stopped. This will not meet the transmission requirements of delay sensitive traffic. For the case of dynamic scheduling, the network device may indicate whether the collision time prioritizes data transmission or prioritizing measurement through DCI (Downlink Control Information ). However, for the pre-configured grant, the resources are pre-configured and do not need to be scheduled every time by DCI, so how to meet the transmission requirements of the delay sensitive traffic in this case needs to be considered.
