Systems and techniques for avoiding inefficiencies resulting from failed handover attempts. A base station selects one or more mobility management entity (MME) pools for assignment to a relay node, with the selection being performed so as to minimize or eliminate handover attempts requiring that a target device support a particular MME pool when the MME pool is not supported by the MME. A base station selects, when communicating with a relay node, a subset of the MME pools that it supports and assigns the subset to the base station. UEs served by the relay node are assigned the MME pool or MME pools assigned to the relay node. The relay node is informed of the MME pools supported by one or more neighbor nodes and, when attempting a handover to a neighbor node, attempts an X2 handover only to neighbor nodes supporting an MME pool assigned to the relay node.

To achieve a greater flexibility when transmitting data according to a hybrid ARQ method, preferably when used in a mobile radio system, a channel-coded bit stream is divided into at lest one first bit stream (A) and one second bit stream (B, C), whereby these parallel bit streams (A-C) are each subjected to a separate bit rate matching, and the resulting bits of the individual bit streams (A-C) are subsequently combined with one another once again in order to transmit in a data packet or in a repeat data packet that is requested on the receiver side.

A method is provided for adapting the data transfer rate of a data flow in a communication device according to which: the data flow can be subdivided into at least one data block containing transmission bits to be transmitted; the transmission bits are formed by a coding process from information-carrying input bits; transmission bits determined from a data block of the data flow are removed (punctured) in order to adapt the data transfer rate; a puncturing pattern stipulates which transmission bits are to be removed, and; the puncturing pattern is constructed in such a manner that transmission bits are preferably removed that, during the coding process, depend on few input bits. The present invention also relates to a corresponding communication device.

It is described a method for controlling the transmission power for a network element being connected to a base station of a cellular telecommunication network via an uplink wireless data connection. The method including providing a first set (set1) of power control parameters (P0—PUSCH—1, α1) and a second set (set2) of power control parameters (P0—PUSCH—2, α2), storing the first set (set1) of power control parameters (P0—PUSCH—1, α1) and the second set (set2) of power control parameters (P0—PUSCH—2, α2) within the network element, using the first set (set1) of power control parameters (P0—PUSCH—2, α1) by the network element for transmitting within a first radio transmission resource, and using the second set (set2) of power control parameters (P0—PUSCH—2, α2) by the network element for transmitting within a second radio transmission resource. Further, it is described a network element and a base station, which are, in connection with each other, adapted to carry out the described transmission power controlling method.
摘要:
It is described a method for distributing radio resources between a first radio link between a primary network element being assigned to a first hierarchic level of a network and a first secondary network element being assigned to a second hierarchic level and a second radio link between the primary network element and a second secondary network element being assigned to the second hierarchic level. The method includes (a) transmitting respectively a first resource allocation parameter from the first and the second secondary network element to a decision unit, the first resource allocation parameter being indicative for a minimum performance requirement, (b) transmitting respectively a second resource allocation parameter from the first and the second secondary network element to the decision unit, the second resource allocation parameter being indicative for a performance increase for the respective radio link following an allocation of additional radio resources, and (c) distributing the radio resources between the first and the second radio link based on the first and the second resource allocation parameter.

摘要:
A mechanism for controlling resources and/or settings of an access network element like a base station is provided which allows an autonomous reconfiguration of, for example, the antenna configuration based on a set of performance indicators in a base station. The base station can reconfigure itself without the need of operator control so that during periods with low capacity demands the base station will reconfigure correspondingly, which may include a reduction of active cells by turning off the power for a part of the installed equipment.
摘要:
The invention relates to a method for transmitting data between a transmitter and a receiver via a wireless data channel of a communication network (CN). The transmitter transmits data to the receiver, where the transmission includes at least one transmission parameter which is selected based on a first channel quality that is known to the transmitter. The receiver receives the data, and the receiver determines the first channel quality known to the transmitter from said data via the at least one used transmission parameter as well as a second, current channel quality via the quality of the received data; and the receiver compares the first channel quality with the second channel quality.
摘要:
A method, apparatus and computer program product are provided for conveying information regarding the antenna configuration and/or the transmission diversity scheme to a recipient, such as a mobile device. In particular, information regarding the antenna configuration and/or the transmission diversity scheme can be conveyed by appropriately mapping a physical broadcast channel within a sub-frame so as to include reference signals indicative of different antenna configurations or transmission diversity schemes. Alternatively, masking, such as cyclic redundancy check masking, can be used to provide information regarding the antenna configuration and/or the transmission diversity scheme.
