摘要： Example embodiments of the present disclosure relate to packets re-routing in a communication network. A first device receives, from a second device, a request for establishing at least one tunnel between the first device and a third device. The first device transmits, to the second device, tunnel information concerning the at least one tunnel to be established between the first device and the third device. The first device receives at least one uplink packet targeted to the first device from a fourth device, via the third device and the at least one tunnel. This solution may avoid uplink packet loss, for example, during the inter-donor-DU migration. In addition, this solution may not violate the security policy in a transport network and IAB-donor-DU. In other words, the source filtering can be applied normally for the re-routed packets.

摘要： Various communication systems may benefit from improved acknowledgment methodology. For example, it may be helpful for a radio link control entity to receive acknowledgment information as soon as possible after the expiration of a poll-retransmission timer. A method may include starting a timer for retransmission of a poll at a protocol entity (110) in an acknowledged mode. The method may also include determining at the protocol entity, upon expiration of the timer, a data packet having a lowest sequence number among one or more data packets (120). In addition, the method may include considering retransmission of the data packet having the lowest sequence number by the protocol entity, regardless of whether new data can be transmitted and of whether any data packets are awaiting transmission (140). Further, the method may include transmitting the data packet having the lowest sequence number by the protocol entity (150).

摘要： There is provided an apparatus comprising means configured to perform routing (S701) at least one packet to a network node on a backhaul link using a primary path, and storing (S703) the at least one packet. The means also configured to perform starting (S705) a discard timer, the discard timer representing a duration of time that the at least one packet will be stored. In response to receiving a failure message before the discard timer expires, the means are configured to perform re- routing (S707) of the stored at least one packet to a further network node using an alternative path.

摘要： Systems, methods, apparatuses, and computer program products for expediting repetition of an unanswered poll for automatic repeat request (ARQ) feedback are provided. One method includes transmitting a poll to a peer protocol entity to trigger status reporting at the peer protocol entity, starting a timer with a duration that is set based on whether at least one predefined condition is met. The at least one predefined condition depends at least on a value of a sequence number (SN) of a protocol data unit (PDU) in which the poll is transmitted. The method may further include re-transmitting a poll when the timer expires.

摘要： A base station, in communication with a UE using a first serving cell, determines a need to perform a security update for the UE and sends a command including information to perform the security update and indication of a time to execute the security update to change to a new security configuration. In response to the time occurring, a security update is performed to a new security configuration for use for communication with the UE using a second serving cell. The UE receives the information and the indication and performs, without performing a random-access procedure, the security update to the new security configuration to use for communication with the second serving cell.
