摘要： Embodiments include methods for a source donor centralized unit (CU) in an integrated access backhaul (IAB) wireless network. Such methods include determining that traffic between the source donor CU and a top-level IAB node in the wireless network needs to be offloaded to a target donor CU in the wireless network. Such methods include sending, to one or more descendant nodes of the source donor CU, a first indication that at least one configuration for traffic between the source donor CU and at least one IAB node is suspended, in association with migration of the top-level IAB node from the source donor CU to the target donor CU. Other embodiments include complementary methods for a target donor CU and for an IAB node, as well as CUs and IAB nodes configured to perform such methods.

摘要： A method for transmission reliability comprises receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed. The message comprises an indication to initiate a second connection with the terminal device from the second network node. The method further comprises establishing, at the second network node, the second connection with the terminal device based on the message. The second network node comprises a third connection established before the first connection failed. The first connection carries data transmitted in the third connection before the first connection failed, and the second connection carries data transmitted in the third connection after the first connection failed. The method for interference coordination utilizes duplicated transmissions to secure data transmission and to prevent data loss in an unexpected system failure.

摘要： According to certain embodiments, a method in a wireless device (110) includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link. In response to receiving the positive acknowledgement, the one or more retransmissions of the PDU or the segment of the PDU on the second link are cancelled.

摘要： A method where a first network node receives from a second network node a packet with a path identifier value in the header. A plurality of bearers associated with the path are determined based on the path identifier value and used to assign at least one resource to the packet before it is transmitted to a third network node based on the at least one resource.

摘要： Transmitters consider the size of a gap segment adjacent to at least one negatively acknowledged (NACKed) Radio Link Control (RLC) Service Data Unit (SDU) when considering when and/or how to concatenate one or more NACKed SDU segments for retransmission. Depending on which RLC SDU segment(s) is/are NACKed, e.g., considering the size of NACKed segments in relation to Protocol Data Unit (PDU) header size(s) needed, the transmitter implements a single RLC SDU retransmission or multiple RLC SDU segment retransmissions. In so doing, the solution presented herein not only defines how such transmissions occur, but also provides improved efficiency when retransmitting such NACKed SDU segments.

摘要： Embodiments herein relate e.g. to a method performed by a communication node for handling communication in a wireless communication network (100). The communication node selects a format of reporting buffer status report, BSR, from a 5 first BSR format and a second BSR format, wherein the first BSR format is associated with expected bits to transmit.

摘要： Embodiments herein relate to e.g. a method performed by a first communication device for controlling transmission of one or more data packets in a wireless communication network. The first communication device transmits an indication, to a second communication device, indicating one or more of the following: a maximum number of duplicates allowed to be transmitted for each data packet; type of duplication; a data radio bearer, DRB, for which duplication is configured; a radio link control, RLC, entity that is allowed to transmit a duplicate; an order of RLC entities in which the second communication device should transmit a first data packet and following duplicates; whether duplication is activated or deactivated for a DRB.

摘要： An access node (111, 112) of a cellular network transmits an identifier (502, 505) enabling selection of access information from an access information table. The access information is applicable by a radio device (10) for accessing the cellular network. Further, the access node transmits (501, 504) timing information indicating a time of a next transmission of the access information table. Depending on the timing information, the radio device (10) may decide whether to switch to another carrier frequency or to wait on a currently used carrier frequency to receive the access information table.

摘要： A method and a first network node (200) of a wireless network, for handling paging of a wireless device. A Radio Access Network Area, RANA, which is supported by the first network node (200), is registered (2:1) in a database (202) by network nodes IN supporting the RANA, including the first network node (200). The network nodes (204) that support the RANA are then identified (2:3) in the database (202). When it is detected (2:2) that a wireless device (D1) needs to be paged in the RANA, e.g. for receiving data, a paging message is distributed (2:4) to the identified set of network nodes (204) as an instruction to perform radio transmission of the paging message. Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node (200), is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database (202).

摘要： Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.
