(57) ABSTRACT A method for performing random access by a User Equip ment (UE) in a
wireless network, comprises configuring at least one UE transmit beam for a transmission of …

One apparatus may determine a first set of parameters associated with a first RACH
procedure, the first set of parameters being associated with beam failure recovery for a first …

Methods and apparatus are described. A method, implemented in a wireless
transmit/receive unit (WTRU) includes monitoring a first control channel search space (SS) …

(57) ABSTRACT A UE may receive a beam modification command that indicates a set of
transmit beam indexes corresponding to a set of transmit beams of a base station, and each …

Methods, apparatuses, and computer-readable mediums associated with a user equipment
(UE) and a base station are provided for herein. In aspects, a UE may receive, from a base …

A beam selection method in a mobile communication system including a base station with
multiple antennas and user equipment conducting radio communication with the base …

A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more
indications of one or more beam indexes corresponding to one or more beams. The first …

Determination of characteristics of a communication envi ronment may be beneficial in many
communication systems. For example, certain wireless communication systems, such as fifth …

A first apparatus may send, to a base station in a first carrier frequency, a request associated
with determination of a first beam used for communication between the base station and the …

In a process of beam change, the base station transmits a beam change instruction to a user
equipment to confirm a change from a current beam to another beam. The base station …
