A method of adapting the output power of a radio transmitting entity within a cage having at least one aperture. The method includes the steps of providing at least one sensor to sense the condition of the at least one aperture and providing a controller to adjust the output power of the radio transmitting entity in accordance with the sensed condition of the at least one aperture.

摘要:
A node (100; 300) of a mobile network is responsible for scheduling transmissions of data blocks between the mobile network and a terminal device (200, 200′). The node (100; 300) may for example be a base station (100) or a control node (300) of the mobile network. The node (100; 300) determines a processing time required by the terminal device (200; 200′) for processing signals for transmission of one of the data blocks. The processing time is determined from a plurality of supported processing times. On the basis of the determined processing time, the node (100; 300) schedules the transmission of the data block. The terminal device (200, 200′) may provide control data for determining the processing time to the node (100; 300).
摘要:
It is proposed to modify data unit handling on the side of a sender (e.g. a sending end-point or a proxy) by introducing congestion notification prevention information into data units, such that a queue buffer that implements a procedure for performing congestion notification with respect to one or more queued data units (e.g. dropping and/or marking data units with explicit congestion information) is capable of preventing the performance of a congestion notification at least with respect to the data units containing the congestion notification prevention information.
摘要:
A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronization that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.
摘要:
A system and method for transporting data units for a communication network. In a communication between two peers a proxy and a network entity for controlling a partial communication are provided. One or both of the proxy and the network entity is arranged to modify one or more of the data units, in order to provide communication control related information that is different from communication control related information exchanged between the two peers The respective other or both of the proxy and the network entity is arranged to perform data unit transmission control based on the different communication control related information.
摘要:
A method of processing a data unit of a first protocol layer for transmission in a data unit based communication system is described, comprising the steps of passing to a second protocol layer a given data unit of said first protocol layer that is to be transmitted, determining a numeric value of a numerically quantifiable parameter associated with said given data unit of said first protocol layer, embedding said given data unit of said first protocol layer into one or more data units of said second protocol layer, performing transmission control for said one or more data units of said second protocol layer in accordance with said numeric value of said numerically quantifiable parameter.
摘要:
A method and device for handling received data units at the receiving peer of a predetermined data unit exchange protocol at a given layer is described, where said method and device carry out a limited ARQ mechanism for received data units, and are characterised by providing the possibility of storing corrupted copies of received data units, and providing a data unit to an upward release handler on the basis of one or more stored corrupted copies of a given data unit after a triggering event terminating the operation of the retransmission request procedure for the given data unit.
摘要:
A method and an apparatus for transmitting error-tolerant data is disclosed employing the ARQ technique, wherein the retransmission of erroneous data is performed up to the point where the remaining amount of errors is acceptable (for instance because the erorrs will not be perceived by the recipient of the information, which can be a person or a higher level protocol with additional error correction capabilities). The number of data blocks (RLC) detected as erroneous is employed to define a reliability measure (RM) and a request for retransmission of the erroneous data blocks is performed until a desired reliability threshold (RT) is reached. An additional threshold with a higher value than the first one can be employed to request for optional retransmission when the reliability measure (RM) is between the first and the second threshold. The retransmission will be performed only if further conditions such as channel availability are met.
