Abstract: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for determining round trip time and layer 2 (e.g., data link) buffer size in non terrestrial networks. In one embodiment, a method performed by a communication node includes: sending a capability request message to a communication device, wherein the communication node communicates from a satellite in orbit; receiving capability information from the communication device in response to the capability request message; and determining a data link buffer size associated with communications between the communication node and the communication device based on the capability information.

Abstract: Techniques are described to generate a first security key when a user equipment operating in an inactive state initiates a data transmission or a procedure to resume network connection. The first security key is generated based on a second security key associated with a first network node and a counter value, and the first security key is associated with a second network node and is used to generate user plane security keys to transmit data to or to receive data from one or more network nodes.

Abstract: Some techniques for efficiently indicating a mapping relationship from physical random access channel preambles and/or random access resource specific to one or more system information blocks in a wireless communication network are described. One example method includes transmitting, from a network node, a message that identifies a number of random access preambles that are reserved for transmissions of system information requests by mobile devices.

Abstract: Provided are a data transmission method and apparatus and a computer storage medium. The method may include: a source Distributed Unit (DU) reports a packet data convergence protocol (PDCP) transmission state report to a source Centralized Unit (CU), where the PDCP transmission state report enables the CU to determine which PDCP protocol data unit (PDU) data is not successfully received by a UE; and the PDCP PDU data which is not successfully received by the UE are retransmitted to the UE via a target DU.

Abstract: The present disclosure describes methods, systems, and devices for scheduling gap coordination. One method includes determining, by a user equipment (UE), a scheduling gap (SG) granularity in a network; and transmitting, by the UE, a message comprising the determined SG granularity to the network. Another method includes receiving, by a network, assistance information from a UE; configuring, by the network based on the assistance information, a SG granularity; transmitting, by the network, reconfiguration information to the UE, the reconfiguration information comprising the determined SG granularity; and receiving, by the network, reconfiguration complete information from the UE.
