Embodiment Construction

[0030] In the prior art, the terminal device repeatedly sends the same uplink transport block on k PUSCHs, but the number of resource units available for UL-SCH transmission in the k PUSCHs may be different. After research, it is found that the factors that may lead to different numbers Including but not limited to at least one of the following:

[0031] 1. The number of symbols contained in the k PUSCHs is different;

[0032] 2. The overhead of Xoh-PUSCH configuration in k PUSCHs may be different;

[0033] 3. The amount of uplink control information to be carried on each of the k PUSCHs is different.

[0034] Then how the terminal device determines the size of the uplink transmission block becomes an urgent problem to be solved.

[0035] In order to make the purpose, technical solution and advantages of this application clearer, the embodiment of this application provides an uplink information transmission method and device, the terminal device obtains the first information...

Abstract

The invention discloses an uplink information transmission method and device. The method comprises: a terminal device obtaining first information sent by a network device; sending a first transmissionblock to the network device in at least one physical uplink shared channel (PUSCH) according to the indication / configuration of the first information; wherein a transport block size of the first transport block corresponds to a reference PUSCH in the at least one PUSCH. Thus, the terminal equipment repeatedly sends the same uplink information transmission block in k PUSCHs, under the condition that the number of resource units which can be used for UL-SCH transmission in k PUSCHs is different, the number of the resource units is different. According to the embodiment of the invention, the first transmission block can be sent to the network device in at least one physical uplink shared channel PUSCH according to the indication / configuration of the first information, so that the effective transmission of uplink information is ensured, and the transmission efficiency and the system performance of a new generation of wireless communication system are improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an uplink information transmission method and device. Background technique [0002] With the development of mobile communication technology, a new generation of wireless communication technology (for example: 5G communication technology) will have higher frequency utilization and energy efficiency, and will also significantly improve communication security and user experience. [0003] In the new generation of wireless communication technology, Physical Uplink Shared Channel (PUSCH; Physical Uplink Shared Channel) resources are used to send an uplink shared channel (UL-SCH; Up Link-Shared Channel) including terminal equipment sending to network equipment. However, in the new-generation antenna communication technology, PUSCH can be divided into two types: the first type is the PUSCH sent by the network device to schedule the downlink control informati...
