Abstract: The present disclosure relates to a serving wireless communication node (AP1) in a wireless communication system (1), wherein the serving node (AP1) is adapted to determine that a served user terminal (2) is going to enter a zone (3) that switches between being reachable and unreachable for the serving node (AP1), and to predict data (xm+1 . . . xn) to be transmitted to the user terminal (2) for at least a part of the time the user terminal (2) is in the zone (3) and is unreachable for the serving node (AP1).

Abstract: For a random access procedure (e.g., 2-step RACH and/or 4-step RACH), a network node may configure different physical random access preamble configurations (e.g., different PRACH occasions, preamble indexes, or preamble formats) for different user equipment (UE)/service groups that are associated with different UE priorities, UE types, service priorities, service types, and/or network slices. A UE may select a configuration to use to transmit the random access preamble based on the priority of the UE, the type of the UE, the priority of the service, the type of the service, and/or the network slice. In 2-step RACH, a network node may also configure different msgA PUSCH resources for different UE priorities, UE types, service priorities, service types, and/or network slices. The UE may transmit the random access preamble in accordance with the selected PRACH configuration as part of a contention based random access procedure.

Abstract: The embodiments herein relate to time domain resource allocation for PUSCH transmission. In one embodiment, there proposes a method in a wireless communication device for Random Access (RA), comprising: transmitting a preamble on Physical Random Access Channel (PRACH); receiving a Random Access Response (RAR) message; transmitting, on Physical Uplink Shared Channel (PUSCH), a message for terminal identification (Msg3), wherein the time resource allocation of Msg3 is different than the time resource allocation of other message to be transmitted on the PUSCH (normal PUSCH). The embodiments herein can support flexible time resource allocation configuration for Msg3, and at the same time, the signaling overhead in RAR/DCI for indicating the time resource allocation of PUSCH carrying Msg3 can be reduced.

Abstract: Embodiments include methods, performed by a network node, for configuring a physical random-access channel (PRACH) of a cell in a time-division-duplexed (TDD) radio access network (RAN). The methods include determining an increase in a level of remote interference in the cell and, in response to determining the increase, selecting a first PRACH configuration from a first subset of available PRACH configurations. The first subset of available PRACH configurations can be more robust against remote interference than a second subset of the available PRACH configurations, and the first subset can be exclusive of the second subset. The methods also include transmitting, to one or more user equipment (UEs) first information indicating that the first PRACH configuration should be used for accessing the cell via the PRACH. Embodiments also include complementary methods performed by UEs, as well as network nodes and UEs configured to perform such methods.
