Abstract

The invention relates to an uplink transmission resource acquisition method, a data transmission method and electronic equipment. The method comprises the following steps: acquiring one or more time-frequency resource RO configurations issued by a network side and used for physical random access channel PRACH transmission and time-frequency resource PO configurations associated with each competition preamble of a corresponding RO in the RO configurations and used for uplink data transmission; according to the acquired RO configuration and the PO configuration associated with the RO configuration, determining an available RO of an RACH transmission type adopted by the current terminal equipment, the RACH transmission type comprising two-step RACH transmission and four-step RACH transmission; and transmitting the selected preamble on the determined RO, and executing uplink data transmission on the PO corresponding to the selected preamble. According to the embodiment of the invention, the signaling overhead of the network side can be effectively reduced, the access delay of the terminal equipment is effectively reduced, and the access efficiency of the terminal equipment is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method for acquiring uplink transmission resources, a method for data transmission, and an electronic device. Background technique [0002] In general, when a terminal device (also referred to as a user terminal UE, User Equipment) needs to establish communication with the network side, it can complete the initial access or To obtain uplink synchronization, RACH transmission types can include 2-step RACH transmission and 4-step RACH transmission. For 4-step RAHC transmission and 2-step RACH transmission, RO (time-frequency domain resources used for physical random access channel transmission, RACHOccasion) and preamble are shared (preamble) scenario, if the terminal device using 2-step RACH and the terminal device using 4-step RACH transmission select the same preamble transmission on the same RO, the network side cannot determine whether the preamble is ...
