Abstract: This disclosure relates generally to adaptive and dynamic paging resource selection and System Information (SI) acquisition in a wireless communication network. Performed by a first network element in a network, the method including: receiving a first message from a second network element of the network; deriving a User Equipment (UE) specific paging resource configuration associated with a UE based on the first message; selecting a paging radio resource based on the UE specific paging resource configuration and based on a radio resource specific paging configuration pre-defined in the first network element; and sending a paging message over the selected paging radio resource to the UE while the UE is in a radio resource control (RRC) inactive state.

Abstract: Techniques are described to generate a first security key when a user equipment operating in an inactive state initiates a data transmission or a procedure to resume network connection. The first security key is generated based on a second security key associated with a first network node and a counter value, and the first security key is associated with a second network node and is used to generate user plane security keys to transmit data to or to receive data from one or more network nodes.

Abstract: Methods, apparatus and systems for transmitting data in a power efficient sate are disclosed. In one embodiment, a method performed by a wireless communication device is disclosed. The method comprises: entering a power efficient state; and transmitting, to a wireless communication node, uplink data while being in the power efficient state.

Abstract: A multicast service information change notification method comprises: an access network element sends to a UE a multicast service information update command; and the access network element indicates multicast service information to the UE service.

Abstract: A synchronization method and system of control sequence numbers is provide to achieve radio link control sequence number synchronization between different network elements. This method includes the following steps: allocating a preset radio link control sequence number to a first radio link control protocol data unit corresponding to a first packet in a data burst and successively allocating a radio link control sequence number to subsequent radio link control protocol data units corresponding to packets of this data burst, when each designated network element in a plurality of designated network elements performing radio link control protocol process on the packets in the data burst received by said each designated network element.

Abstract: A resource allocation method for dynamic multiplexing of Multimedia Broadcast Multicast Service (MBMS) can be used to improve resource utilization efficiency when multimedia multicast services share a channel. A network side device configures a Modulation and Coding Scheme (MCS) for said logical channels or the Multicast/Broadcast over Single Frequency Network (MBSFN) subframes bearing said logical channels according to the transmission requirements of logical channels, and implements modulation and coding processing for the data of Physical Multicast Channel (PMCH) borne by MBSFN subframes bearing said logical channels by using said MCS. The network side device can employ different modulation and coding in the physical layer according to different Quality of Service (QoS) requirements of different logical channels of MBMS services, thereby achieving the purpose of improving resource utilization efficiency and satisfying different service requirements.

Abstract: The present invention discloses a synchronization scheduling method. The method includes that: sending a plurality of data bursts of a specified service by an upper network element to specified network elements belonging to the upper network element, wherein data packets of the data bursts include time stamp information so that the specified network elements send the data bursts according to the time stamp information; and setting difference between the time stamp information of every two adjacent data bursts by the upper network element to be an integer multiple of the TDM period of the specified service, wherein length of the TDM period is one of exactly divided parts of a system frame number period of a radio interface.
