The apparatus receives a multicast-broadcast single frequency network (MBSFN) signal transmitted from a base station, decodes the received MBSFN signal, and retrieves at least one source symbol from the decoded MBSFN signal when the node is capable of retrieving a source symbol. The apparatus also generates at least one redundancy version of the MBSFN signal based on the retrieved at least one source symbol and transmits the at least one redundancy version of the MBSFN signal via MBSFN. Generating a redundancy version of the MBSFN signal includes applying forward error correction (FEC) on the retrieved at least one source symbol to generate at least one repair symbol. Thus, a redundancy version of the MBSFN signal includes the at least one repair symbol and a subset of the at least one source symbol. | 2014-05-08 |
20140126455 | ENCODING INFORMATION IN BEACON SIGNALS - Systems and methodologies are described that facilitate transmitting at least two different types of information in a single signal, whereby the different types of information can be encoded and decoded independently. Thus, changes to one type of information does not affect a second type of information. | 2014-05-08 |
20140126456 | METHOD OF PROVIDING MOBILE IPTV SERVICE AND SYSTEM USING THE SAME - The method of providing a mobile IPTV service, performed in a terminal that receives streams of all channels belonging to a channel group of a currently viewed channel, includes, when a channel is selected, determining whether the selected channel and the currently viewed channel belong to the same channel group, and when the selected channel and the currently viewed channel are determined to belong to the same channel group, decoding, by the terminal, an IPTV channel stream of the selected channel within a currently received channel Therefore, since the channel group is generated based on channel selection preference, and a multicast stream including a channel stream of the channel group is broadcast, it is possible to decrease average processing complexity and to guarantee rapid channel change when a user changes the channel to another channel in the same channel group. | 2014-05-08 |
20140126457 | Method and system for transmitting MBMS control information in multicarrier aggregation system - A method and system for transmitting Multimedia Broadcast Multicast Service (MBMS) control information in a multicarrier aggregation system are disclosed in embodiments of the disclosure. The method includes that: when an MBMS needs to be sent, a network side determines an MBMS-including Component Carrier (CC) and a non-MBMS-including CC, and sends service control information and service data of the MBMS in the MBMS-including CC. The method further includes that: the network side sends, in the non-MBMS-including CC, related control information of the MBMS in the MBMS-including CC. With technical solutions provided by the embodiments of the disclosure, a UE operating or residing in a non-MBMS-including CC can find out timely and accurately the initiation of a session for a UE-interested MBMS in an MBMS-including CC, so as to avoid premature blind gathering of UEs in the MBMS-including CC, thus effectively decreasing duration of impact on uplink random access by the MBMS-including CC. | 2014-05-08 |
20140126458 | METHOD OF PROCESSING SIGNALING OF TERMINALS OF SUBSCRIBERS IN A MOBILE COMMUNICATION SYSTEM - The present invention relates to a method and a device that control signals for a plurality of terminals possessed by the same user. More particularly, a method of controlling signals for a plurality of terminals using a mobility management entity (MME) according to an embodiment of the present invention is characterized by including the steps of: setting terminals with the same subscriber codes and the same mobility as grouping terminals; and transmitting group signals on the grouping terminals to a base station. According to the present invention, the following advantages are realized: of enabling the prevention of waste in having to report mobility-related information on each terminal and being able to simultaneously transmit grouping or other signals to all terminals that are in a group in a network. | 2014-05-08 |
20140126459 | METHOD AND APPARATUS FOR TRANSMITTING BROADCASTING MESSAGE IN WIRELESS ACCESS SYSTEM SUPPORTING M2M ENVIRONMENT - The present invention relates to a wireless access system supporting an M2M environment, and provides a method and an apparatus for broadcasting a medium access control (MAC) control message. A method for receiving a broadcasting message from the wireless access system supporting the M2M environment, according to one embodiment of the present invention, comprises the steps of: an M2M equipment receiving a broadcast allocation map information element including a message type field, which shows the type of the broadcasting message, and resource allocation information, which shows an allocation region of a broadcasting burst from which the broadcasting message is transmitted; and the M2M equipment confirming the type of the broadcasting message which is shown by the message type field, wherein when the broadcasting message type is related to the M2M equipment, the M2M equipment receives the broadcasting message through the broadcasting burst that is indicated by the resource allocation information, and when the broadcasting message type is not related to the M2M equipment, the M2M equipment does not decode the broadcasting burst that is indicated by the resource allocation information. | 2014-05-08 |
20140126460 | TERMINAL AND A METHOD FOR ESTABLISHING A CELLULAR NETWORK CONNECTION BETWEEN A TERMINAL AND A BASE STATION - A terminal may include a generator configured to generate a request for radio network resources from a cellular network; a transmitter configured to transmit the request for radio network resources to a relay device, wherein the request for radio network resources may be configured to be forwarded by the relay device to a base station of the cellular network; and a controller configured to establish a cellular network connection between the terminal and the base station of the cellular network using radio network resources assigned to the terminal by the cellular network. | 2014-05-08 |
20140126461 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR RELAY OPERATION IN WI-FI NETWORKS - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: determining, by a wireless relay device, a first time window allocated for a first network, allowing first maximum transmit power for packet transmissions; and determining, by the wireless relay device, a second time window allocated for a second network, wherein the second time window is allowed for transmissions also within the first network, but only with second maximum transmit power that is lower than the first maximum transmit power. | 2014-05-08 |
