摘要： A method of calibrating transmit and/or receive paths of an antenna comprising at least two antenna columns, each of which comprising two co-located sub-arrays of antenna elements. The method includes the steps of transmitting a measurement signal on at least one of the antenna elements, and receiving a representation of the measurement signal on at least one other of the antenna elements, the representation comprising at least a mutual coupling component dependent on the mutual coupling between the at least one antenna element and the at least one other antenna element. Further, the method includes the steps of repeating the transmitting and receiving step for at least a subset of all combinations of antenna elements of the antenna, wherein each combination of antenna elements comprises antenna elements having a same or different polarization, and subsequently comparing the received representations of the measurement signal between different combinations of antenna elements, and estimating at least a respective phase difference between antenna elements with the same polarization based on the comparison. Finally, the method includes the step of calibrating transmit and/or receive paths of antenna elements with the same polarization based on the estimated phase difference.

摘要： A method in a primary network node for handling a handover of a wireless device from a primary cell serviced by the primary network node to a neighbor cell serviced by a neighbor network node. The method comprises sending a configuration message to the wireless device, comprising instructions to evaluate in parallel a first handover event and a second handover event. The first event is based on signal quality measurements from both cells. The second event is based on signal strength measurements from both cells. To evaluate comprises determining if an entering condition for each of the events is satisfied. The method further comprises sending a handover command to the wireless device when one of: the entering condition for the first handover event is satisfied over a first time period, and the entering condition for the second handover event is satisfied over a second time period.

摘要： Systems and methods for explicitly signaling a number of receiver antennas of one node in a cellular communications network to another node in the cellular communications network are disclosed. In one embodiment, a first node in the cellular communications network sends a number of receiver antennas of the first node to a second node in the cellular communications network. In one embodiment, the first node broadcasts the number of receiver antennas of the first node. In another embodiment, the first node unicasts the number of receiver antennas of the first node to the second node. The second node then utilizes the number of receiver antennas of the first node to perform a desired action.

摘要： A method executed by an optical line terminal (OLT) in a passive optical network (PON). The PON includes a plurality of optical network units (ONUs) coupled with the OLT through an optical fiber, the ONUs sharing a bandwidth of the optical fiber. The method includes receiving, from the ONU, an energy conservation message indicating support for the reduced buffer memory size. The reduced buffer memory size is calculated based on the maximum committed transmission rate and the burst size limit for the downstream traffic intended for the ONU. A notification is transmitted to the ONU indicating that a portion of the buffer memory can be powered down such that only the reduced size of the buffer memory remains in operation, and downstream traffic intended for the ONU is transmitted at an average transmission rate and burst size not exceeding the maximum committed transmission rate and the burst size limit.

摘要： A method for handling digital certificates in a communication network is described. The communication network comprises a first certificate authority (110-116) having issued at least one digital certificate. The method comprises determining (216) whether a revocation condition for revoking the at least one digital certificate is fulfilled. The at least one digital certificate has been issued by the first certificate authority, wherein the at least one digital certificate is valid and is not revoked. The method further comprises, based on a result of the step of determining (216), revoking (404), by the first certificate authority (110-116), the at least one digital certificate, and based on the result of the step of determining (216), issuing, by a second certificate authority (110-116), at least one further digital certificate for the revoked at least one digital certificate. An associated system, methods in involved network entities, the involved network entities, and computer programs are also described. Therefore security handling in the communication network which may be fluctuating with respect to its number of network nodes and/or which may comprise numerous network nodes may be performed in an easy and efficient way.

摘要： A method for a GSM/EDGE node (105, 130), comprising establishing a TBF to another node and entering a transmit state in which data blocks are transmitted via said TBF to said other node. The transmit state is left if (205) there are no data blocks to transmit and positive ACK/NACKs have been received for transmitted data blocks, and, upon leaving said transmit state, a timer is started for the release of said TBF and a predefined TBF mode is entered in which the TBF is regarded (230) as released if the TBF release timer expires before data blocks are received by the network node to transmit to the other node, while, if data blocks are received by the network node to transmit to the receiving node, the predefined TBF mode is exited, the timer is stopped (225) and reset, and the first state is entered.

摘要： A method of Dual Radio Access Transfer of an IP Multimedia Subsystem, IMS, controlled voice or video call in an alerting phase for the Packet Switched, PS, to Circuit Switched, CS, direction. The method comprises initiating a SIP session towards a terminating mobile station, UE and, during a voice or video call alerting phase, making a determination at the UE that a DRVCC transfer is required from a PS to a CS access. The method comprises sending a SIP message in the initiated SIP session from the UE to a Service Centralization and Continuity Application Server, SCC-AS, the SIP message including a request to initiate session transfer from PS to CS, and responding to receipt of the SIP message at the SCC-AS by sending a SIP INVITE from the SCC-AS towards the UE, the INVITE including the Session Transfer Number, STN, as the calling party identity, and receiving the INVITE at a Mobile Switching Centre, MSC, serving the UE in the CS access. The method further comprises responding to receipt of said INVITE at the MSC, or to receipt of associated CS signalling, by sending from the MSC to the UE a CS Setup message, whereupon the MSC is placed in a state in which it expects a CS Answer from the UE.
