  • Patent number: 9854564
    Abstract: In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.

  • Publication number: 20170318496
    Abstract: An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.

  • Patent number: 9807688
    Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble. If the RACH preamble was explicitly signaled by the network, a downlink channel is monitored until a new transmission is indicated according to radio resource allocation information received from the network. If the RACH preamble was not explicitly signaled by the network, a contention resolution timer is started and the downlink channel is monitored until the contention resolution timer expires. Such monitoring of downlink channels in a more efficient manner, results in effective reduction in power consumption.

  • Publication number: 20170303213
    Abstract: A method is provided for performing, by a user equipment (UE), a power headroom reporting (PHR) procedure in a wireless communication system. In a first PHR procedure, a first PHR is triggered, and it is determined that a first uplink (UL) resource cannot accommodate a PHR media access control (MAC) control element (CE) plus its subheader. The PHR MAC CE is not transmitted in the first PHR procedure and it is determined that the first PHR is not cancelled. Further, in a second PHR procedure, a second PHR is triggered, and it is determined that at least one PHR, including the first PHR and the second PHR, has been triggered and not cancelled. It is then determined that a second UL resource can accommodate a PHR MAC CE plus its subheader, and the PHR MAC CE is transmitted by using the second UL resource to an eNodeB (eNB).
