摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.
摘要翻译：在这种情况下描述的技术有助于用无线电基站的用户终端的随机接入。用户终端确定第一类型的上行链路扰频序列中的一个，并且使用所确定的第一类型的上行链路扰频序列来生成随机接入消息。随机接入消息被发送到基站。用户终端从基站接收第二种不同类型的上行加扰序列，并将其用于与无线基站的后续通信。例如，第一上行链路扰频序列可以与无线电基站的小区区域或与无线电基站相关联的随机接入无线电信道具体地关联，但是它们没有被特别分配给任何用户终端，并且第二上行链路加扰序列可以从可专用于各个用户终端的第二组上行链路扰频序列中选择。

摘要： A method for scheduling a first and a second channel in a subframe includes dividing transmission resources needed for the first channel into a first set of resource groups and assigning the resource groups of the first set to subelements in the subframe in a predetermined fashion. The method also includes assigning a symbol value to all subelements in the subframe which have not been assigned a resource group of the first set and dividing transmission resources needed for the second channel into a second set of resource groups. Additionally, the method includes assigning, in a predetermined fashion, the resource groups of the second set to subelements in the subframe by means of said symbol values.

摘要： A method of providing signal synchronization for a radio access network may include transmitting a first carrier including synchronization signals on a first frequency from the radio access network. Information relating the first carrier on the first frequency with a second carrier on a second frequency may be transmitted from the radio access network, with this information being intended to be used in synchronization by a wireless terminal upon addition of the second carrier. More particularly, the first and second frequencies may be different. A command to add the second carrier as a downlink for transmissions may be transmitted to the wireless terminal. Related network nodes and wireless terminals are also discussed.

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.

摘要： The present invention relates to a first node and a second node in a mobile telecommunication network. The network comprises a first node, a second node and a third node, wherein the first node is connectable to the second node and the second node is connectable to the first node and to the third node and the third node is connectable to the second node. A system function is realized by the execution of a master-process implemented in the first node and a slave-process implemented in the third node, wherein the execution of the master-process realizes a control function associated with the system function. The master-process of the first node is adapted to temporarily delegate the responsibility to realize the control function to a master-proxy-process implemented in the second node and the master-proxy-process implemented in the second node is adapted to take over the responsibility to realize the control function from the master-process of the first node.

摘要： The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

摘要： The invention relates to a method of sending control information from a first node to a second node in a communications system providing a plurality of resource units for the transmission of data. The control information is sent by use of a code book comprising at least one code word identifying control information relating to data transmission over a resource unit. The code book is dynamically updated by means of repeatedly transmitting an updated version of code book information from the first node to the second node. The invention also relates to a first communications node comprising means for transmitting control information to a second node. The means for transmitting control information is adapted to transmitting the control information by use of a code book; and to repeatedly transmitting an updated version of code book information in order to achieve that the code book is dynamic.

摘要： Methods and arrangements in a network node and mobile terminal, respectively, in a wireless communication system supporting aggregation of component carriers. The method in a network node involves, when resources on at least two downlink component carriers are being assigned to a mobile terminal at the same time, allocating (908) control information bits not related to power control in a bit field, which is normally used for power control in a message on a physical downlink control channel associated with one of said at least two downlink component carriers. The method in a mobile terminal involves, using control information bits not related to power control obtained from a bit field, which is normally used for power control in a message on a physical downlink control channel associated with one of said at least two downlink component carriers, for locating information related to downlink or uplink transmissions.
