Abstract: Systems and methods for reflective mapping of flows to radio bearers are provided. In some embodiments, a method of operation of a radio access node includes determining a flow-to-radio bearer mapping by determining a radio bearer to which to map a flow. The method also includes mapping the flow to the radio bearer according to the flow-to-radio bearer mapping, where the radio bearer is different than a previous radio bearer to which the flow was mapped and transmitting a downlink transmission for the flow on the radio bearer according to the flow-to-radio bearer mapping. The downlink transmission includes a flow identifier of the flow. In this way, a flow may be quickly mapped to another radio bearer for a wireless device. This may be for when the transmission of a flow starts or changes in characteristics. Also, control signaling is reduced between the radio access node and the wireless device.

Abstract: A method may be provided to operate a CU node that is coupled with first and second DU nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link. A message is received at the CU node from the first DU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication between the CU node and the mobile communication device through the first DU node is suspended, wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained. While suspending communication between the CU node and the mobile communication device through the first DU node, communication may be provided between the CU node and the mobile communication device through the second DU node over a second radio link.

Abstract: A mobile station is configured to support handover from a source base station to a target base station. The mobile station receives signaling from the target base station that indicates Packet Data Convergence Protocol (PDCP) protocol data units which have been successfully received at the target base station. In response, the mobile station generates further PDCP protocol data units for missing PDCP service data units from corresponding PDCP service data units buffered at the mobile station. The generating comprises using a different header compression state from that which was used for the missing PDCP service data units and ciphering specific to a connection with the target base station. The mobile station transmits the further PDCP protocol data units to the target base station.

Abstract: A base station of a mobile communication network supports continuity of a Multimedia Broadcast Multicast Service, MBMS, for a terminal. The base station receives, from the terminal, an information element informing the base station of a combination of bands, which the terminal supports for carrier aggregation. The terminal supports MBMS reception on any carrier configurable as a serving cell for the terminal according to the information element. The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS.

Abstract: A wireless device 108 and a method for mapping data packets to radio bearers in a wireless communication network 100. A Radio Network Node (RNN) 110 and the wireless device are operating in the wireless communications network. The wireless devices evaluates whether or not a data packet matches a packet filter in a first group of packet filters and/or a packet filter in a second group of packet filters. When the data packet does neither match a packet filter in the first group of packet filters nor a packet filter in the second group of packet filters, the wireless device maps the data packet to a default radio bearer.

The transmitting communication device determines a control element, e.g., a control element of a Media Access Control protocol, associated with one of the carriers and provides the control element with an identifier specifying the carrier the control element is associated with. The transmitting communication device sends the control element with the identifier on one of the carriers to the receiving communication device. The receiving communication device receives the control element and determines, from the identifier received with the control element, the carrier the control element is associated with. Further, the receiving communication device determines, on the basis of parameters indicated by the control element, a data transmission property of the carrier the control element is associated with.

Abstract: An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.

Abstract: A communication system includes a transmitting communication device (310) and a receiving communication device (320). The transmitting communication device (310) determines a control element, e.g., a control element of a Media Access Control protocol, associated with one of the carriers and provides the control element with an identifier specifying the carrier the control element is associated with. The transmitting communication device (310) sends the control element with the identifier on one of the carriers to the receiving communication device (320). The receiving communication device (320) receives the control element and determines, from the identifier received with the control element, the carrier the control element is associated with. Further, the receiving communication device (320) determines, on the basis of parameters indicated by the control element, a data transmission property of the carrier the control element is associated with.

Abstract: The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.

Abstract: A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes that a number of data units that has been transmitted by the sending node are missing. The receiving node sends a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.
