Abstract: An apparatus and method for providing multimedia broadcast and multicast services in a CDMA (Code Division Multiple Access) mobile communication system. The apparatus and method enable a common MBMC (Multimedia Broadcast/Multicast Control) layer to be allocated between a plurality of cells, enable MBMC layers to be classified on the basis of types of services, and use the classified MBMC layers. That is, individual MBMC layers do not have to store large-capacity data because a unique service or transmission rate in each of cells is based on a slow rate, and the individual MBMC layers corresponding to respective cells process a service requiring complex scheduling. Moreover, the apparatus and method enable the same information to be provided to a plurality of cells and enable a streaming-type service to be processed in a common MBMC layer commonly used in the cells. The apparatus and method can not only reduce an overhead of storage and processing devices but also minimize a time difference between broadcast and multicast timings of different cells, by enabling the common MBMC layer to commonly process MBMS information for the plurality of cells.

Abstract translation: 一种用于在CDMA（码分多址）移动通信系统中提供多媒体广播和组播服务的装置和方法。 该装置和方法使得能够在多个小区之间分配公共MBMC（多媒体广播/多播控制）层，使得可以基于服务类型对MBMC层进行分类，并使用分类的MBMC层。 也就是说，单个MBMC层不必存储大容量数据，因为每个小区中的唯一服务或传输速率基于慢速率，并且对应于相应小区的各个MBMC层处理需要复杂调度的服务。 此外，该装置和方法使得能够向多个小区提供相同的信息，并且能够在小区中通常使用的公共MBMC层中处理流式服务。 该装置和方法不仅可以减少存储和处理设备的开销，而且通过使公共MBMC层能够共同处理多个小区的MBMS信息，从而最小化不同小区广播和组播定时之间的时差。

Abstract: A method for providing soft handover in a code division multiple access mobile communication system supporting multicast multimedia broadcast service. In an asynchronous mobile communication system supporting an MBMS service, when a UE moves to a region where it can receive data from a plurality of Node Bs, soft handover is performed on the UE. Thus, even though an MBMS user moves from an existing cell to a new cell, a stable MBMS service is provided. Furthermore, the UE can soft-combine data received from a plurality of Node Bs.

Abstract: A method of performing an inter-RAT measurement for a handover from NB-TDD to GSM is provided. A UE, as it moves from an NB-TDD Node B to a GSM cell, receives a measurement control message from the NB-TDD Node B. The UE then measures the strength of a signal received from the GSM cell and verifies its identification for a predetermined measuring time. If the UE successfully verifies the identification of the GSM cell for the measuring time, it reports the signal strength measurement and the verified GSM cell identification to the NB-TDD Node B. If the UE fails to verify the identification of the GSM cell for the measuring time, it reports only the signal strength measurement to the NB-TDD Node B.

Abstract: A method of adjusting the transmission time of data in a CDMA communication system. A UE (User Equipment) measures the time difference between the received time of a downlink DPCH (Dedicated Physical Channel) and the transmitted time of an uplink DPCH and reports it to an RNC (Radio Network Controller). The RNC transmits transmission time adjustment information to a node B and the UE if the time difference is out of a predetermined range. The node B then adjusts the transmission time of the downlink DPCH according to the transmission time adjustment information and transmits the downlink DPCH at the adjusted time. The UE receives the downlink DPCH by adjusting a search time for the downlink DPCH according to the transmission time adjustment information.

Abstract: An apparatus for retransmitting data using hybrid automatic retransmission request (HARQ) in a mobile communication system. A radio network controller (RNC) determines maximum waiting time for retransmission of the data, and transmits the determined maximum waiting time to a Node B and a user equipment (UE). The Node B (a) receives the maximum waiting time and transmitting the data to the UE; (b) upon detecting a retransmission request for the data from the UE, retransmits the data and sets the maximum waiting time; and (c) upon detecting a second retransmission request for the data due to abnormal receipt of the retransmitted data from the UE after a lapse of the maximum waiting time, prevents retransmission of the data. The UE (a) receives the maximum waiting time; (b) if an error exists in data received from the Node B, transmits a retransmission request for the data to the Node B and sets the maximum waiting time; and (c) waits for the retransmitted data only for the maximum waiting time.

Abstract: A method for transmitting information in a mobile communication system using HSDPA (High Speed Downlink Packet Access) service. When an RNC (Radio Network Controller) generates or changes HSDPA service-related information, it transmits the generated or changed information to a Node B and a UE along with an indicator indicating the change in the HSDPA service information. Therefore, the Node B and the UE simultaneously operate by receiving the generated or changed information, resulting in an increase in the HSDPA service efficiency.

Abstract: A radio network controller (RNC) transmits a power offset for controlling transmission power of an uplink high-speed dedicated physical control channel (HS-DPCCH) when a user equipment (UE) enters a handover region, in a mobile communication system including the RNC, a Node B connected to the RNC, and the UE located in one of at least two cell areas occupied by the Node B. The Node B transmits data to the UE over a high-speed downlink shared channel (HS-DSCH) and the UE transmits information indicating reception of the data to the Node B over the uplink HS-DPCCH. The RNC informs the UE of a power offset for determining a transmission power increment of the uplink HS-DPCCH, if it is determined that the UE is located in the handover region. The RNC informs the Node B of the power offset so that the Node B can determine a threshold value for determining information indicating reception of the data, depending on the power offset.
