  • Publication number: 20230319895
    Abstract: A user equipment (UE) receives a timing advance medium access control (MAC) control element. The UE applies a timing advance command of the timing advance MAC control element and to start or restart a time alignment timer. The UE releases physical uplink control channel (PUCCH) resources and releases any assignment sounding reference signal (SRS) resources, when the time alignment timer expires. The UE flushes hybrid automatic request (HARQ) buffers, when the time alignment timer expires or is stopped.

  • Patent number: 11672018
    Abstract: A mobile communication technology, and, more particularly, a method for efficiently transmitting data stored in a message 3 (Msg3) buffer and a user equipment for the same is disclosed. The method of transmitting data by a user equipment in uplink includes receiving an uplink (UP) Grant signal from a base station on a specific message, determining whether there is data stored in a message 3 (Msg3) buffer when receiving the UL Grant signal on the specific message, determining whether the specific message is a random access response message, and transmitting the data stored in the Msg3 buffer to the base station using the UL Grant signal received on the specific message, if there is data stored in the Msg3 buffer when receiving the UL Grant signal on the specific message and the specific message is the random access response message.

  • Publication number: 20220210672
    Abstract: A PDCP status report can be transmitted with reduced radio resources by transmitting the reception success or failure of a series of PDCP service data units (SDUs) in the form of a bitmap when configuring the PDCP status report. A PDCP control packet data unit (PDU) is generated to communicate a status report to a transmitting node for one or more PDCP SDUs transmitted from the transmitting node. The PDCP control PDU includes a data/control (D/C) bit field to indicate the PDCP control PDU is a control PDU, a control PDU type field to indicate a type of corresponding control information, a sequence number field to indicate a first missing PDCP SDU, and a bitmap field for a variable length bitmap. A bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received.

  • Publication number: 20220174595
    Abstract: A mobile terminal performs a random access procedure with a network that includes transmitting to the network a random access preamble directly allocated to the mobile terminal by the network and receiving a random access response from the network in response to transmission of the random access preamble. The terminal performs a discontinuous reception (DRX) operation that controls how the mobile terminal monitors a physical downlink control channel (PDCCH).

  • Patent number: 11272449
    Abstract: A random access channel (RACH) procedure includes a mobile terminal receiving from a network a message that indicates a RACH preamble for the mobile terminal. The terminal transmits the RACH preamble to the network and then receives a RACH response from the network. The terminal monitors a downlink channel according to a discontinuous reception (DRX) active time for radio resource allocation information for a data transmission by the terminal. The DRX active time specifies a time until the radio resource allocation information for the data transmission is indicated.

  • Patent number: 10966185
    Abstract: A method for a user equipment (UE) to generate a transmission is provided. In this method, a UE starts a time alignment timer when a time alignment command is received. The UE receives an uplink grant; and generates an initial transmission or a retransmission according to the uplink grant only when the time alignment timer is running upon receiving the uplink grant. In addition, the uplink grant is received through a Physical Downlink Control Channel (PDCCH) indicated by a Cell Radio Network Temporary Identifier (C-RNTI) of the UE.
