A paging method for an MBMS service is provided. To efficiently transmit MBMS control information in an MBMS mobile communication system, an RNC transmits to a Node B a control message including a list of NI information for MBMS paging groups by the RNC and the Node B establishes a physical channel according to the control message and transmits an MICH including NIs to UEs on the established physical channel.

A method for ciphering MBMS (Multimedia Broadcast/Multicast Service) data in a wired/wireless communication system is provided. The MBMS service enables the same service or desired services to be provided to a number of users. In the ciphering method, a ciphering key for encoding MBMS data is previously provided to an authorized UE, and the authorized UE is informed of when MBMS data encoded using the ciphering key is to be transmitted, thereby preventing unauthorized UEs from illegally receiving the MBMS service.
摘要:
A mobile communication system supporting an MBMS service includes a Node B having a plurality of transport channels and at least one UE communicating with the Node B. The Node B selects a transport channel for MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel; transmits a system information block indicating the selected transport channel to a cell area where UEs are located, using a primary common control physical channel; and transmits the MBMS control information to the cell area using the selected transport channel. The UE receives a system information block indicating a transport channel selected to transmit MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel, over a primary common control physical channel; receives the MBMS control information over the selected transport channel among the plurality of the transport channels, using the system information block; and receives the MBMS service using the MBMS control information.

摘要:
A method and apparatus for enabling partial combining on a Multimedia Broadcast/Multicast Service (MBMS) service are provided where a radio network controller (RNC) specifically informs a user equipment (UE) whether an MBMS service signal of the current cell is combinable with the same MBMS service signals received from different cells for each individual service or timing, through an MCCH or an MSCH, which is a type of a logical channel for an MBMS service, in a Uu interface. The UE combines the MBMS service signals transmitted from the different cells, thereby obtaining a gain in terms of utilization of transmission power and radio resources.

An apparatus and method for controlling the transmission power of a DSCH in a mobile communication system is disclosed. In the DSCH transmission power controlling method, a UE generates information for controlling the transmission power of the DSCH based on a channel condition determined by the reception power of a CPICH from a node B transmitting the DSCH to the UE, and then transmits the power control information to the node B.
摘要:
An RNC determines parameters available for measurement of a synchronization signal and second Node B information from a second Node B, transmits the determined parameters to a first Node B during radio link setup and to a UE during radio bearer setup, and transmits parameter selection information to the first Node B and the UE, if it is recognized that measurement of the synchronization signal and the second Node B information is necessary. The first Node B changes a position of a downlink time period over which a downlink channel is transmitted from the first Node B to the UE and a position of an uplink time period over which an uplink channel is transmitted from the UE to the first Node B, according to parameters selected from the parameters. The UE receives the synchronization signal and the second Node B information in the remaining time periods except the changed downlink time period and the changed uplink time period among the plurality of time periods.
摘要:
An encoding method and apparatus for a DCH (Dedicated Channel) encoder and a DSCH (Downlink Shared Channel) encoder in a transmitter for a mobile communication system including the DCH encoder for encoding k bits among 10 input TFCI (Transport Format Combination Indicator) bits and the DSCH encoder for encoding remaining (10-k) bits among the input TFCI bits. The method comprises generating, by the DCH encoder, a first coded bit stream by encoding the k input bits into 32 bits, and outputting a (3k+1)-bit stream by puncturing the first coded bit stream according to a specific mask pattern corresponding to the k value; and generating, by the DSCH encoder, a second coded bit stream by encoding the (10-k) input bits into 32 bits, and outputting a {3*(10-k)+1}-bit stream by puncturing the second coded bit stream according to a specific mask pattern corresponding to the (10-k) value.
