  • Publication number: 20190200251
    Abstract: This disclosure provides a transmission status reporting apparatus and method and communication system. The method includes: obtaining information on transmission rate difference and/or information on scheduling latency difference between a plurality of radio links; the information on transmission rate difference is obtained based on information on transmission statuses of radio links successfully transmitting PDCP layer data packets, and the information on scheduling latency difference is obtained based on information on transmission statuses of radio links transmitting RRC layer data packets. Hence, an accurate reference basis may be provided for a transmitting device in determining whether a current network is suitable to performing duplication transmission, gains and losses between wasted radio resources and reduced latency in the multi-connection duplication transmission mode may be better weighted, and a more suitable data transmission mode or flow control mode may be configured.

  • Publication number: 20190182797
    Abstract: An area identifying apparatus and method and a communication system. The area identifying method includes: receiving, by a UE, area identification information used for identifying an area transmitted by a base station; comparing the received area identification information with area identification information currently stored in the UE; and determining whether an area where the UE is located is changed according to a result of comparison. Hence, whether the area where the UE is located is changed or which area the UE is located may be efficiently identified.

  • Patent number: 10313938
    Abstract: A deactivation method and apparatus for a secondary cell and a communications system. The deactivation method includes: restarting a deactivation timer associated with a first SCell carrying a PUCCH, in a case where a deactivation timer is restarted or a channel quality indicator report is transmitted in any second SCell in a secondary PUCCH cell group. Hence, a case will not occur where understanding of an activation state of a secondary cell by a UE and a base station is inconsistent due to an UE autonomous deactivation mechanism.

  • Publication number: 20180368203
    Abstract: A transmission apparatus and method of status indication and a communication system. The transmission method of status indication includes: determining whether an RLC layer has successfully received all RLC PDUs of uplink data when a base station receives the uplink data transmitted by a UE; and transmitting PDCCH information to the UE, in a case where the RLC layer has successfully received all the RLC PDUs of the uplink data; the PDCCH information is used to indicate that the uplink data have been successfully received and/or the UE is permitted to enter into a DRX status. Hence, not only transmission of RLC status report may be reduced and transmission efficiency of the whole system may be improved, but also the UE may be made to enter into the DRX status as fast as possible and power consumption of the UE may be lowered.

  • Publication number: 20180270789
    Abstract: An updating apparatus and method for an access control parameter and a communication system. The updating method includes: determining by a UE access class barring information for performing access control and update period information for updating the access class barring information; and updating the access class barring information by the UE based on the update period information. The UE itself improves fairness of the access, and the network side updates the access control parameter only when the network payload is modified, which may lower power consumption of the UE in access, avoid frequent occurrence of paging and reduce use of broadcast resources of the system.

  • Publication number: 20180206168
    Abstract: A processing apparatus and method for network indication and a communications system in a procedure of RC-IWK. The processing method includes: a base station determines whether UE context release indication contains information on a cause of release indicating that a traffic of a UE is steered from the LTE to the WLAN, when the UE context release indication transmitted by an MME; and initiates a connection reconfiguration procedure to the UE so that the UE is kept in a connected state, in a case where the UE context release indication contains the information on the cause of release indicating that the traffic of the UE is steered from the LTE to the WLAN. Hence, a case, for example, where the UE not expecting to use the LTE is steered to the LTE system again, will not occur.
