  • Publication number: 20210195655
    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.

  • Patent number: 10972940
    Abstract: A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.

  • Publication number: 20210051493
    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: 20200344685
    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: 10757650
    Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is received.
