US 10,542,562 B2 · Apparatus and method for managing random access channel configuration in wireless communication system

Abstract

The present disclosure is related to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate than a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, a method for operating a base station in a wireless communication system is provided. The method comprises: generating remaining minimum system information (RMSI) comprising random access channel (RACH) configuration, wherein the RACH configuration comprises an association between RACH resources and one of a synchronization signal (SS) block and channel state information reference signal (CSI-RS) resources; and transmitting, to a user equipment (UE), the RMSI.

Dependent claims

A method for operating a base station in a wireless communication system, the method comprising:

transmitting, to a user equipment (UE), one or more synchronization signal (SS) blocks based on one or more beams, wherein each of the one or more SS blocks includes primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast channel (PBCH);
transmitting, to the UE, system information including random access channel (RACH) configuration, wherein the RACH configuration includes:
information regarding a number of RACH occasions;
and
information regarding a subset of the RACH occasions associated with each of the one or more SS blocks;
and
receiving, from the UE, a random access preamble on a RACH occasion based on information included in the RACH configuration,
wherein the RACH occasion is associated with a SS block identified from the one or more SS blocks.

5 more elements

A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver;
and
at least one processor coupled to the transceiver, configured to:
control the transceiver to receive, from a base station, one or more synchronization signal (SS) blocks transmitted based on one or more beams, wherein each of the one or more SS blocks includes primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast channel (PBCH);
control the transceiver to receive, from the base station, system information including random access channel (RACH) configuration, wherein the RACH configuration includes:
information regarding a number of RACH occasions;
and
information regarding a subset of the RACH occasions associated with each of the one or more SS blocks;
and
control the transceiver to transmit, to the base station, a random access preamble on a RACH occasion based on information included in the RACH configuration,
wherein the RACH occasion is associated with a SS block identified from the one or more SS blocks.
