Title:
UPLINK SHARED CHANNEL CONFIGURATION METHOD FOR RANDOM ACCESS, RANDOM CHANNEL ACCESS METHOD, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/228544
Kind Code:
A1
Abstract:
The present application discloses an uplink shared channel configuration method for a random access, the method comprising the following steps: determining a time-frequency resource position for each PO type in a PUSCH configuration period; determining a relative positional relationship between each set of random access channel occasion elements and a set of uplink shared channel occasion elements in the PUSCH configuration period; and determining a correspondence relationship between PRACH resource elements and PUSCH resource elements. The present application further comprises a random channel access method applicable to network apparatuses and terminal apparatuses. The present application further provides a network apparatus and a terminal apparatus applicable to the channel configuration method. The method and the apparatus of the present application are directed towards MsgA in 2-step RACH, and address the issue of configuration of a mapping relationship from an RO and a preamble sequence ID to a DMRS configuration adopted by a PO and a PUSCH in a system, such that a base station is capable of utilizing the mapping relationship to determine, according to a detected RO and preamble sequence ID, a DMRS configuration adopted by a PO and a PUSCH.
