Abstract: A method of connection establishment through a relay UE for a remote UE is proposed. The remote and relay UEs first perform discovery and establish a PC5 radio resource control (PC5-RRC) connection. Upon receiving a request from the remote UE, the relay UE and a serving gNB perform a relaying procedure for establishment of the remote UE's signalling radio bearer 1 (SRB1). The relay UE configures PC5 RLC channels for relaying of SRB1 towards the remote UE. The remote UE then enters an RRC_CONNECTED state. The remote UE and gNB establish security. The gNB configures additional data radio bearers (DRBs) for relaying. The relay UE configures PC5 RLC channels for relaying of the additional DRBs towards the remote UE. The DRBs can then be used for exchange of data between the remote UE and the gNB.

Abstract: An encryption mechanism used on cooperative multi-band wireless STA architecture that enables full duplex operations. In encrypting a frame, an AAD can be constructed by using a selected MAC address, which may not be associated with a band to be used for transmitting the frame in an upcoming TXOP. An STA that supports simultaneous transmission in a multi-band operation uses the same MAC address to encrypt the frames to be transmitted on different bands. An AAD is constructed by using a same MAC address corresponding to one of the transceivers. A transmit STA may specify band information used for encryption in the MAC header, which serves to signal the receive STA to decrypt the frame by using the proper information.

Abstract: Systems and methods of transmitting and receiving a Wake-Up Radio (WUR) packet by using a simplified preamble structure that contains no training field. The preamble carries a signature sequence selected from a set of predefined sequences, each corresponding to a different data transmission rate. The preamble and the control information of the WUR packet are transmitted in the same rate as indicated by the selected sequence. Hence, a receiving WUR can determine the data transmission rate and locate the associated control information directly if a sequence that matches a predefined signature sequence is detected. The same sequence or in combination with an additional sequence in the preamble may also be used to indicate automatic gain control synchronization, packet type and other related information.

Abstract: A method supporting enhanced network identity (NID) provisioning under User Equipment (UE) mobility scenarios between different types of networks is proposed. When a UE registers to an SNPN, the UE is assigned with a 5G-GUTI by the SNPN. The SNPN is identified by an SNPN ID==PLMN ID+NID. When the UE moves from the SNPN to another target network having a target AMF, the UE triggers a mobility registration update procedure and provides the 5G-GUTI along with NID information in a Registration Request to the target AMF. The target AMF can use the NID information along with the 5G-GUTI to find a source AMF for deriving UE context for the subsequent operations during the mobility registration update procedure. Providing NID information along with 5G-GUTI can assist the target AMF to find the source AMF efficiently, preventing a potential registration procedure failure.
