US 2022/0287080 A1 · METHOD AND DEVICE FOR CONFIGURING SEARCH SPACE, METHOD AND DEVICE FOR RANDOM ACCESSING, AND STORAGE MEDIUM

Abstract

A method for configuring a search space includes: generating, by an access network equipment, search space configuration information, the search space configuration information including a configuration of a first search space and a configuration of a second search space, the configuration of the first search space being configured to indicate the first search space for carrying a first physical downlink control channel (PDCCH), the first PDCCH being a PDCCH corresponding to message B in a 2-step random access channel (RACH) procedure, the configuration of the second search space being configured to indicate the second search space for carrying a second PDCCH, the second PDCCH being a PDCCH corresponding to message 2 in a 4-step RACH procedure, the first search space and the second search space are different search spaces; and transmitting, by the access network equipment, the search space configuration information.

A method for configuring a search space, comprising:

generating, by an access network equipment, search space configuration information, the search space configuration information comprising
a first configuration of a first search space and a second configuration of a second search space, the first configuration being configured to indicate the first search space for carrying a first physical downlink control channel (PDCCH), the first PDCCH corresponding to message B in a 2-step random access channel (RACH) procedure, the second configuration being configured to indicate the second search space for carrying a second PDCCH, the second PDCCH corresponding to message 2 in a 4-step RACH procedure, the first search space and the second search space being different search spaces;
and
transmitting, by the access network equipment, the search space configuration information.

A method for random accessing, comprising:

receiving, by an access network equipment, message A in a 2-step random access channel (RACH) procedure, from a first terminal;
determining, by the access network equipment, a search space for carrying a third physical downlink control channel (PDCCH) from a first search space and a second search space, the third PDCCH corresponding to a response message of the message A;
and
transmitting, by the access network equipment, the third PDCCH on a resource corresponding to the determined search space;
wherein, the first search space is configured to carry a first PDCCH, the first PDCCH corresponding to message B in the 2-step RACH procedure, and the second search space is configured to carry a second PDCCH, the second PDCCH corresponding to message 2 in a 4-step RACH procedure, and the first search space and the second search space are different search spaces.
