One example discloses a wireless device, comprising: an input configured to receive an interference signal; a transmitter configured to generate a transmit signal having either a first data rate or a second data rate; and a controller coupled to the input and the transmitter, and configured to define an interference threshold; wherein the controller is configured to command the transmitter to modulate the transmit signal at the first data rate if the interference signal is below the interference threshold, and modulate the transmit signal at the second data rate if the interference signal is above the interference threshold.

Methods and systems for dynamically adjusting a data rate in a wireless connection. The method and system include a source device and a sink device configured to establish a wireless connection. The quality of the wireless connection is monitored, and, should the quality degrade so as to satisfy a triggering event, the source controller can adjust the data rate, e.g., the bit rate or sample rate, used to reduce the number of dropped, lost, or retransmitted packets. The reduction in bit rate and/or sample rate results in packets of decreased size and additional unused air-time. The unused air-time provided can be filled with at least a portion of a frame of data originally associated with another packet. This will result in at least one packet being free to include additional retransmission packets. Additionally, should the quality of the connection improve, the source controller can adjust increase the data rate accordingly.

The method (700) includes, in response to receiving the indication to discard the radio link control service data unit, transmitting (706) information indicating to discard the radio link control service data unit.

A system includes a method for detecting a signal interference in a communication signal of a wireless communication system. An identified source of the signal interference is determined according to an interference profile of a plurality of interference profiles associated with an interference profile library having information that approximates characteristics of the signal interference. The signal interference of the communication signal is mitigated according to an interference parameter associated with the identified source by filtering the communication signal according to the interference parameter.

In an aspect, a server may receive trip information a wireless device, receive network coverage map information representing a different network coverage areas, predict a travel time for the wireless device to reach the network coverage area with reduced signal quality, predict a travel duration of the wireless device within that network coverage area, and transmit a notification to the wireless device to enable preloading appropriate data before entering the network coverage area. Further aspects include wireless devices configure to communicate with the server and preloading appropriate data before entering the network coverage area

There is provided a communication device capable of determining whether admission of new data traffic is allowed or rejected not by comparing throughputs only, but by considering other parameters when the data traffic is admitted. A communication device (10) according to the present invention includes a determination unit (11) that determines whether to admit a flow regarding a new radio terminal (30), the flow being to be transmitted between a radio terminal (30) and a base station (20) and having a transmission deadline, depending on a transmission state of a plurality of data packets included in the flow, and a communication unit (12) that transmits, to the base station (20), instruction information indicating whether to admit the flow regarding the new radio terminal (30).

Certain aspects of the present disclosure provide techniques for wireless communication. The method generally includes determining one or more target metrics associated with a file having a plurality of packets, the plurality of packets comprising at least one of a plurality of uplink packets or a plurality of downlink packets, determining one or more communication parameters for communicating the plurality of packets according to the one or more target metrics associated with the file, and communicating the plurality of packets with a second network entity in accordance with the determined one or more communication parameters.

A wireless device receives message(s) comprising parameters of cells grouped into: a primary control channel group comprising a primary cell with a primary control channel, and a secondary control channel group comprising a control channel secondary cell with a secondary control channel. Parameters comprise RRC dedicated parameters. A secondary cell other than the control channel secondary cell is mapped to the secondary control channel group if a first control channel parameter is present in the RRC dedicated parameters of the secondary cell when the secondary cell is added to the cells. Otherwise the secondary cell is mapped to the primary control channel group. A secondary cell is considered to be the control channel secondary cell if second control channel parameters are present in the RRC dedicated parameters. First channel state information is transmitted via the secondary control channel. Second channel state information is transmitted via the primary control channel.

A method in a network node comprises: detecting a Quality of Service (QoS) Violated Event in respect of a particular QoS flow of a Protocol Data Unit (PDU) session; and sending a corresponding QoS violated event report to any one or more of: a Session Management Function (SMF) of the network; a Policy Control Function (PCF) of the network; an Application Function (AF) of the network; and a third party service provider.

There is provided a method comprising: preparing a data packet for transmission on a bearer, wherein at least one of the following is configured for transmission: a first network node and a second network node, checking whether at least one predetermined criterion is met, selecting, based at least partly on the said checking, whether to transmit the data packet via the first network node, via the second network node, or via both the first and the second network nodes, and transmitting the data packet according to the selecting.
