specific Embodiment 1

[0198] Applied to the scene of self-contained Self-contained structure.

[0199]In NR, the Self-contained structure can be used for one or more timeinterval time intervals. Its main advantage is that this structure does not need to define the timing relationship between the more complicated time domain timeinterval, and has good compatibility and scalability. Taking the time interval as a Slot as an example, the processing of uplink data transmission preparation, downlink data demodulation reception and response response, and downlink channel information measurement feedback are all completed within one Slot. In this case, a reasonable and sufficient design to support Self-contained as much as possible without increasing complexity requires a more flexible method for determining the location of transmission resources.

specific Embodiment 2

[0237] Case 2: DL Data processing for downlink data processing

[0238] Figure 18 as well as Figure 19The time difference between t1 and t2 is the maximum downlink data demodulation and response information preparation time, where t1 and t2 represent time positions, which can be collectively referred to as DL Data processing. It should be noted that the position of the DCI sent on the PDCCH is not necessarily in the first symbol, but may exist in the 2nd and 3rd symbols, which will reduce the time difference between t1 and t2. PUCCH is divided into two types: long format and short format. The number of occupied symbols can also be one or more, and the starting position can also be moved forward or backward.

[0239] Factors affecting the processing time requirements of DL Data processing include at least one of the following:

[0240] 1. Mapping parameter: If a CB is mapped to multiple symbols, it will take longer processing time because it needs to receive all the infor...

specific Embodiment 3

[0283]Case 3: CSI processing of channel information:

[0284] The DCI transmitted in the PDCCH is used to trigger the feedback of the CSI, and the calculation of the CSI involves two parts, a channel measurement part and an interference measurement part. The channel measurement part mainly uses CSI-RS, and other types of RS can also be used. The interference measurement part mainly uses IMR. The CSI-RS / IMR can be triggered by the DCI, or configured before the DCI is sent.

[0285] If the position of CSI-RS or IMR is after DCI, on Figure 22 , Figure 23 The time difference between t1 and t2 is the maximum downlink data demodulation and response information preparation time, which can be collectively called DL Data processing. CSI can be fed back in PUCCH, and PUCCH is divided into two types: long format and short format. The number of symbols occupied can also be one or more, and the starting position can also be moved forward or backward. The CSI can also be fed back in...

Abstract

The invention provides a configuration method and a configuration device of a start symbol position of an uplink data channel, and a storage medium. The method comprises the steps of determining a configuration value of a first kind of parameter sets, wherein the first kind of parameter sets is sets of uplink data parameters; determining a configuration range of the start symbol position of the uplink data channel according to the configuration value of the first kind of parameter sets; and selecting the start symbol position of the uplink data channel within the configuration range of the start symbol position of the uplink data channel, and informing a receiving terminal of the selected start symbol position of the uplink data channel. Therefore, the problem that in related technologies,the terminal processing service is high in cost and inflexible in time can be solved, and the effects of reducing the service processing cost and flexibly performing service processing are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and storage medium for configuring the start symbol position of an uplink data channel. Background technique [0002] In a wireless communication system, terminals need to handle various types of tasks on the baseband. These tasks mainly include the following categories: [0003] Uplink data transmission preparation: The terminal receives the physical downlink control information (Downlink Control Information, DCI) sent by the base station, and needs to complete baseband processing tasks such as data coding and modulation, precoding, etc. within a limited time. [0004] Demodulation and reception of downlink data: After receiving the downlink data sent by the base station, the terminal needs to complete the tasks of demodulation reference signal estimation, demodulation and decoding within a limited time, and judge whether the code block is received correctly,...
