摘要： The present disclosure provides a novel method for feature activation in the Machine Type Communication and a device thereof. According to the present disclosure, the MTC device may actively trigger entry into or exit from a feature state of the MTC device, and inform the network to perform suitable configuration, so as to meet the requirements of the MTC scenario and optimize the network performance. Furthermore, for the Extra Low Power Consumption feature, it is also proposed to set a MTC device specific DRX cycle as its actual cycle such that the actual cycle may be not limited by the system default DRX configuration information. Therefore, power consumption for the MTC device in the Extra Low Power Consumption state may be reduced.

摘要： In order to address the problem of RLC layer relaying in the prior art that downlink user data of a user equipment with an access through a relay station may be lost due to a handover, the invention proposes solutions of a method and apparatus for controlling downlink data transmission in a multi-hop relay communication system so that when a next-hop network device of a base station is a relay station, an RLC entity of the base station transmits an indication message to a PDCP entity of the base station, to trigger the PDCP entity of the base station to discard a PDCP SDU corresponding to at least one PDCP PDU, upon reception of a user equipment delivery acknowledgement message from the access relay station to acknowledge delivery of the at least one PDCP PDU to the user equipment. The access relay generates the user equipment delivery acknowledgement message upon reception from the user equipment of positive acknowledgement messages for all the RLC PDUs corresponding to the at least one PDCP PDU. Preferably status information on whether an RLC SDU has been acknowledged, which is buffered between the access relay station and the base station, can be synchronized implicitly.

摘要： The present invention provides a network access method and system for Machine Type Communications (MTC), wherein the method comprises the following steps: an MTC device sends a preamble to a base station; the base station sends a Random Access Response (RAR) to the MTC device; if the RAR does not contain a temporary access resource assignment indication, the MTC device sends a Layer 2/Layer 3 message to the base station; otherwise, the MTC device re-attempts to perform network access; the base station sends a contention resolution message to the MTC device; if the contention resolution message contains a self-identification contained in the Layer 2/Layer 3 message sent by the MTC device, the network access is completed; if the contention resolution message contains the temporary access resource assignment indication, the MTC device re-attempts to perform the network access; otherwise, the MTC device attempts to perform the network access using the originally used access resource again. According to the present invention, it is enabled to dynamically and quickly perform assignment and release of MTC access resources based on actual access resource collisions, which thereby avoids waste of uplink resources in a semi-static configuration, reduces the possibility of collision, and protects normal access of non-MTC devices.
