摘要： A radio communications link is established between radio stations, and a semi-persistent radio resource is allocated to support data transmission over the communications link. The semi-persistent radio resource is associated with a corresponding automatic repeat request (ARQ) process identifier. Non-limiting examples of a semi-persistent radio resource include a regularly scheduled transmission time interval, frame, subframe, or time slot during which to transmit a data unit over the radio interface. Retransmission is requested of a data unit transmitted using the semi-persistent radio resource. The ARQ process identifier associated with the semi-persistent resource is used to match a retransmission of a data unit dynamically scheduled on the communications link with the requested data unit retransmission. In a preferred example embodiment, the ARQ process identifier is a hybrid ARQ (HARQ) process, where a retransmitted data unit is combined with a previously-received version of the data unit.

摘要： A method for selecting one or more secondary cells, SCells for supporting communication with a user equipment, UE, by carrier aggregation, CA. The one or more SCells is/are selected from a set of SCell candidates available for an access node. The method includes estimating a probability that the UE connected to a primary cell, PCell, of the access node is in coverage of an SCell in the set of candidates, predicting available resources for the SCell, calculating a CA value for the SCell based on the estimated probability, an estimated spectral efficiency and the predicted available resources, and calculating a CA value for each SCell of the set of SCell candidates, ranking the SCells of the set of SCell candidates based on their calculated CA values, and selecting one or more SCells for providing CA with the UE based on the ranking.

摘要： Methods, systems and network devices for operating a network node to provide dual connectivity in a handover of a user equipment, UE, in a new radio telecommunications system are provided. Methods include sending, from the network node and to a target secondary node, an addition request message to allocate resources for the UE in the handover. Operations include receiving an addition request acknowledgement message from the target secondary node. The addition request acknowledgement message includes a context indication regarding a full radio resource control, RRC, context or a delta RRC context. The delta RRC context includes data that is updated relative to data in a current UE context. Operations include determining, based on context indication, a type of RRC context to provide to the target secondary node.

摘要： According to an exemplary embodiment a method may be provided to operate a central unit, CU, node that is coupled with first and second distributed unit, DU, nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link between the first DU node and the mobile communication device. A message is received from the first DU node informing the CU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication 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 through the first DU node, communication may be provided through the second DU node over a second radio link between the second DU node and the mobile communication device.
