A first communication device for transmitting data to a second communication device comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise compressing a first packet to a first compressed packet according to a compressor instance, wherein the first packet is associated to a flow identity (ID); generating a first Protocol Data Unit (PDU) comprising the flow ID and the first compressed packet; associating a first sequence number (SN) to the first PDU; encrypting the first PDU to a first encrypted packet; generating a first Packet Data Convergence Protocol (PDCP) PDU comprising the first SN and the first encrypted packet; and transmitting the first PDCP PDU via a first logical channel (LC) to the second communication device.

Embodiments of a Next Generation Node B (gNB) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may include a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an El interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.

Example embodiments of the present disclosure relate to UP transmission for a device in an inactive state. The first device in an inactive state performs a small data transmission procedure between the first device and a second device and transmits an indication to the second device. The indication indicates the following a presence of non-small data transmission data to be transmitted by the first device and information associated with the data. Through this solution, the second device may make a proper and reasonable determination about whether to resume a radio resource control connection with the terminal device and whether to stop the ongoing small data transmission procedure.

A method for a random access (RA) procedure performed by a user equipment (UE) having a specific access identity value is provided. The method comprises receiving a mapping table from a base station; transmitting a first RA preamble to the base station; receiving a random access response (RAR) including a backoff value; setting a resultant backoff value by multiplying the backoff value by a specific backoff multiplier corresponding to the specific access identity value in a case that the specific access identity value is included in the mapping table and an indication corresponding to the specific access identity value is not a specific value; setting the resultant backoff value to the backoff value in a case that the specific access identity value is not included in the mapping table; and transmitting a second RA preamble to the base station after a duration indicated by the resultant backoff value expires.

An information processing method is provided. The method comprises: reporting UE policy information corresponding to at least one network identifier to a network side, wherein the at least one network identifier is a network identifier corresponding to part of UE policy information currently stored in the terminal device.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a group of UEs, including the UE, associated with a common set of parameters indicated in multicast or broadcast traffic, wherein the configuration includes a group identifier associated with the group of UEs; and receive the multicast or broadcast traffic over a radio access network (RAN) in a physical downlink shared channel (PDSCH) communication, wherein the group identifier is used to identify that the multicast or broadcast traffic is intended for the UE. Numerous other aspects are provided.
