摘要： A method in a transmitting radio node for scheduling service data flows within a radio bearer towards a receiving radio node in a radio communications network is provided. The transmitting radio node maps data packets of at least two service data flows within the radio bearer to a respective pre-scheduling queue at a PDCP layer, wherein each pre-scheduling queue is associated with a service or a service quality requirement of the respective service data flow. The transmitting radio node further pre-schedules the data packets of the respective pre-scheduling queue down to a scheduling queue at a RLC or a MAC layer. The transmitting radio node further schedules the data packets in the scheduling queue towards the receiving radio node. The transmitting radio node takes a prebuffer time of a data packet queued in the pre-scheduling queue into account when pre-scheduling and/or scheduling the data packets.

摘要： The present disclosure concerns radio communication. More particularly, the present disclosure inter alia introduces methods and means for improved radio access bearer (RAB) release, particularly in situations when there is a RAB limitation requirement. According to one embodiment, a method is performed by a radio network node. The radio network node is handling a set of RABs. This set of RABs consists of one or more RABs. Information related to each RAB of the set of RABs is obtained (130). The obtained information is processed (140) to generate a predicted timing of a next data transmission for each RAB. Also, a ranking is determined (150) for each RAB. This ranking is determined based on the predicted timing. Furthermore, a subset of the set of RABs is selected (160) based on the determined ranking. The subset of the set of RABs is selected (160) in such way that a cardinality of the selected subset complies with a RAB limitation requirement. Finally, any RAB of the set of RABs which is not in the selected subset is released (170), whereas any RAB of the set of RABs which is in the selected subset is kept (180).

摘要： Embodiments herein relate to a method in a transmitting radio node (12) for scheduling service data flows within a radio bearer towards a receiving radio node (10) in a radio communications network (1). The transmitting radio node (12) identifies at least two service data flows within the radio bearer towards the receiving radio node (10), where each service data flow is associated with a service and/or a service quality requirement. The service and/or the service quality requirement is different for respective service data flow. The transmitting radio node (12) maps a Packet Data Convergence Protocol, PDCP, Service Data Unit, SDU, of respective service data flow to a respective scheduling queue on a PDCP layer. Each scheduling queue is associated with the service and/or the service quality requirement of the respective service data flow. The transmitting radio node (12) schedules the PDCP SDUs within the scheduling queues of the at least two service data flows, to the receiving radio node (10), based on the service and/or the service quality requirement associated with the respective scheduling queue on the PDCP layer.

摘要： A node (100, 200) of a cellular network controls sending of first uplink grants to a communication device (10). The first uplink grants indicate first uplink radio resources allocated to the communication device (10) and are sent in response to receiving scheduling requests from the communication device (10). Further, the node (100, 200) controls sending of second uplink grants to the communication device (10). The second uplink grants indicate second uplink radio resources allocated to the communication device (10) and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device (10) and the configured periodicity of sending the second uplink grants, the node (100, 200) controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.

摘要： A pre-scheduling grant transmission method performed by a network node includes issuing a first sequence of pre-scheduling grants to provide a UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting data relating to at least transmitted uplink traffic initiated by the first pre-scheduling grants to obtain a data set providing a statistical description of the traffic flow during the time period covered by the first sequence of pre-scheduling grants, predicting from the obtained data set the time when the next data packet arrives to the send buffer of the UE, and transmitting at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time, thereby providing the UE with timely resources for transmitting the data packet shortly after the packet has arrived at the UE send buffer.

摘要： A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.

摘要： There is provided a pre-scheduling grant transmission method performed by a network node. The method comprises the steps of issuing (S1) a first sequence of pre-scheduling grants on a downlink to a User Equipment, UE, providing the UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting (S2) data relating to at least transmitted uplink traffic initiated by the transmitted first pre-scheduling grants in order to obtain a data set providing a statistical description of the traffic flow of at least transmitted uplink traffic during the time period covered by the first sequence of pre-scheduling grants, predicting (S3), based on at least a subset of the obtained data set, the time when the next data packet arrives to the send buffer of the UE; and transmitting (S4) at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time when the next data packet arrives at the UE send buffer to thereby provide the UE with timely resources to enable the UE to transmit the data packet shortly after the packet has arrived at the UE send buffer. There is also disclosed a network node configured for pre-scheduling grant transmission.
