RANDOM ACCESS METHOD AND TERMINAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18009589 titled 'RANDOM ACCESS METHOD AND TERMINAL
Simplified Explanation
- The patent application describes a method and terminal for improving uplink coverage in high frequency band communication systems such as 5G and 6G. - The method involves configuring multiple Supplementary Uplink (SUL) channels in a cell to supplement uplink coverage. - The network device sends configuration information of the SUL channels to the terminal device. - The terminal device selects one SUL channel for random access based on the configuration information. - The use of multiple SUL channels allows a large number of terminals in the cell to access the network and improves the success rate of uplink random access. - The terminal is specifically designed to select a first SUL channel for random access from the available SUL channels.
Original Abstract Submitted
Embodiments of this application disclose a random access method and a terminal, applied to the communication field, to improve uplink coverage in high frequency band communication systems such as 5G and 6G communication systems. The method in embodiments of this application includes: A network device configures a plurality of SULs in one cell, where the plurality of SULs are used to supplement uplink coverage of the cell; the network device sends configuration information of the plurality of SULs to a terminal device; and after receiving the configuration information, the terminal device may select one SUL used for random access from the plurality of SULs based on the configuration information. In embodiments of this application, because the cell includes the plurality of SULs, a requirement that a large quantity of terminals in the cell can access a network can be met, and a success rate of uplink random access by the plurality of terminals is improved. Embodiments of this application further provide a terminal. The terminal is configured to select a first SUL used for random access from a plurality of SULs.
