Abstract:
A method and apparatus for performing a plurality of network attachment procedures to support a plurality of cells for a small cell-based User Equipment (UE) service are disclosed.
Abstract:
The present invention provides methods and apparatuses for supporting or controlling a small cell on or off procedure. One of the embodiment of the present application, the method comprises steps of receiving, by the MSC from a Source Small Cell (SSC), a cell indication message including a cell state change indication parameter indicating whether the SSC is to be off and a cell off timer parameter indicating a time duration for a cell off process; transmitting, by the MSC to the SSC, a cell off request message in order to accommodate an user equipment (UE) serviced from the SSC based on the cell state change indication parameter; and receiving, by the MSC from the SSC, an aggregated UE context transfer message requesting to perform a radio resource control (RRC) connection switching from the SSC to the MSC during a time duration indicated by the cell off timer parameter.
Abstract:
According to one embodiment of the present application, a method for transmitting a physical uplink control channel (PUCCH) by a terminal in a wireless communication system comprises a step of receiving setting information associated with a PUCCH, and a step of transmitting the PUCCH on the basis of the setting information. The PUCCH is transmitted from a specific PUCCH resource selected from among overlapped PUCCH resources. The specific PUCCH resource is characterized by being associated with beam failure recovery (BFR).
Abstract:
In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a common control channel (CCCH) service data unit (SDU) on a physical uplink channel (PUSCH). The UE receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU may include a MAC PDU associated with a contention resolution identity (CRID) in the MAC PDU. The UE determines whether a MAC SDU is present or not in the MAC PDU, based on the MAC SDU indicator associated with a CRID in the MAC PDU in a state in which the CRID matches the CCCH SDU.

Abstract:
A method and apparatus for dynamic configuration of a maximum number of sidelink retransmissions for a data unit in a wireless communication system is provided. A first wireless device in sidelink receives, from a network, information related to a first retransmission number for a first logical channel and a second retransmission number for a second logical channel. The first wireless device determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and performs sidelink transmission of the data unit to a second wireless device based on the retransmission number of the data unit.
Abstract:
In the present disclosure, a transmitting device generates a medium access control (MAC) protocol data unit (PDU) including a MAC subPDU, and transmits the MAC PDU. The MAC subPDU includes a MAC subheader for a MAC service data unit (SDU) of a logical channel. The MAC subheader includes a length field regarding a length of the MAC SDU of the logical channel, and no logical channel identifier (LCID) field for identifying the logical channel.

A wireless device receives, from a network, information related to a first retransmission number for a first logical channel and second retransmission number for a second logical channel, determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and transmits, to the network, information for the retransmission number of the data unit.
Abstract:
A method for transmitting data by a user equipment (UE), includes configuring a Physical Uplink Shared Channel (PUSCH) configuration related to a physical random access channel (PRACH), wherein the PUSCH configuration includes parameters fora time interval for allocating PUSCH zones and a number of contiguous PUSCH zones in time domain, and transmitting the PRACH and a PUSCH based on the PUSCH configuration.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a power headroom reporting in wireless communication system, the method comprising: generating a PHR MAC CE including PH information per BWP within a serving cell, in a state that the UE is configured with one or more BWPs per serving cell; and transmitting the PHR MAC CE, wherein the PHR MAC CE includes a BWP bitmap indicating presence of the PH information per BWP within the serving cell, wherein the BWP bitmap is present when the serving cell is activated.
