The present disclosure is related to a UE, a network node, and methods for feature based random access. A method at a UE for performing a random access (RA) procedure with a network node comprises: transmitting, to the network node, a first message comprising a physical random access channel (PRACH) preamble to initiate the RA procedure: receiving, from the network node, a second message in response to the first message: determining whether a feature is to be performed or not at least partially based on at least one of the second message, a configuration at the UE, and a capability of the UE; and transmitting, to the network node, a third message with or without the feature performed depending on a result of the determination.

The disclosure provides a method and a device for wireless communication. A first signaling is received, the first signaling including a first identifier and a second identifier; and a first signal is transmitted; wherein the first signaling is used for determining a first time-frequency resource set and a second time-frequency resource set, the first time-frequency resource set and the second time-frequency resource set are associated to the first identifier and the second identifier respectively, the first time-frequency resource set and the second time-frequency resource set are both used for random access. Through reasonably associating the second identifier to the second time-frequency resources in K1 cells, with the first node transmitting K2 candidate cells to facilitate random access, the disclosure improves the rate of successful access.

A method comprising: receiving configurations for a plurality of entry points for initial random access from an access point; determining random access resources for one or more entry points; and initiating, based on one or more criteria relating to properties of the apparatus or a network, at least one random access process with at least one of said entry points.

A terminal apparatus, which executes a two-step random access procedure or a four-step random access procedure to establish a connection with a base station apparatus, executes control such that, in a case where a first message of the two-step random access procedure including a preamble and predetermined information for connection establishment is transmitted and a number of unsuccessful attempts to receive the first message by the base station apparatus exceeds a predetermined number, the terminal apparatus transmits a second message to be transmitted from the terminal apparatus to the base station apparatus in the four-step random access procedure.

Methods and apparatuses for handling measurement operations in a wireless communication system are provided. A method performed by a User Equipment (UE) includes receiving a first measurement configuration from a first serving cell; performing, in a first Radio Resource Control (RRC) state which is an RRC idle state or an RRC inactive state, a first measurement operation based on the first measurement configuration; generating a first measurement result; receiving a first measurement report request from a second serving cell; retaining the first measurement result after the UE transitions from the first RRC state to a second RRC state which is an RRC connected state; and transmitting the first measurement result to the second serving cell, wherein the first serving cell and the first RRC state are associated with a first Radio Access Technology (RAT) and the second serving cell and the second RRC state are associated with a second RAT.

Aspects are provided which allow coverage enhancement and support in NTNs for repetition, frequency hopping, and antenna switching during msgA transmissions based on a preamble-to-PO mapping. In one aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with at least one PO for two-step random access, where the PO spans a time interval greater than one slot. In another aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with a plurality of POs for two-step random access. In a further aspect, the base station provides the UE a plurality of configurations each indicating a PO for two-step random access. In an additional aspect, the base station provides the UE a configuration indicating a guard band for a PO for two-step random access, where the guard band is indicated in units of subcarriers spanning less than one PRB.

Methods and apparatuses for downlink control information. A method at a network device comprises determining a format of downlink control information (DCI) used for scheduling of downlink shared channel in a 2-step random access procedure. The method further comprises determining an identifier used for scrambling cyclic redundancy check (CRC) of the format of DCI. The identifier comprises at least one of a common identifier or a specific identifier. The method further comprises transmitting information regarding a scheduled downlink shared channel with the format of DCI with the CRC scrambled by the identifier on a downlink control channel to at least one terminal device.
