    Abstract: Methods and apparatus are provided for the RRC message segmentation. In one novel aspect, the UE obtains the size Z of the RRC message and the size limit L of the underlying transmission at layer S of the UE protocol stack, wherein the layer S either the RRC layer, the PDCP layer, or a sublayer between an RRC layer and a PDCP layer. The UE triggers RRC message segmentation upon detecting Z is greater than L. In another embodiment, the layer R of the protocol stack of the UE receives, in order, a sequence of chunks of an RRC message, reassembles of the RRC message, wherein the layer R is selected from a same layer as the layer S and a layer higher than the layer S. In one novel aspect, the size limitation L is either predefined or obtained through network notification or UE inquiry.

    Abstract: Mechanism of relay UE discovery and relay UE selection and reselection for remote UE data transmission with a serving base station via relay UE is proposed. A method operable for relay UE selection and reselection of remote UE is provided. The UE considers additional criteria such as relay load other than purely radio signal quality (e.g., RSRP) criteria. The relay load can serve different purpose for relay UE and remote UE. The relay load can be the criteria for UE to become a relay UE or not. It can be the criteria for a remote UE to select another UE as its relay UE.

    Abstract: A method is provided to support remote UE transmitting recommended bit rate query to the base station via the processing of relay UE. In one novel aspect, a new sidelink MAC CE is introduced to indicate the desired bit rate for a specific sidelink logical channel or for a specific Uu/SL radio bearer. In one novel aspect, after receiving the recommended bit rate query MAC CE, the relay UE forwards the MAC CE of this remote UE to the base station over Uu interface after adding information related to remote UE identity. In one novel aspect, the recommended bit rate query MAC CE, when received by the relay UE, is mapped to a specific uplink logical channel priority value or a specific uplink logical channel priority level, which can be used to compare priority with other UL data or UL MAC CE.

    Abstract: Methods and apparatus are provided for the RRC message segmentation. In one novel aspect, the UE obtains the size Z of the RRC message and the size limit L of the underlying transmission at layer S of the UE protocol stack, wherein the layer S either the RRC layer, the PDCP layer, or a sublayer between an RRC layer and a PDCP layer. The UE triggers RRC message segmentation upon detecting Z is greater than L. In another embodiment, the layer R of the protocol stack of the UE receives, in order, a sequence of chunks of an RRC message, reassembles of the RRC message, wherein the layer R is selected from a same layer as the layer S and a layer higher than the layer S. In one novel aspect, the size limitation L is either predefined or obtained through network notification or UE inquiry.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, configurations of one or more measurement gaps for the UE to perform measurements of PRSs. The UE receives an indication for selecting one measurement gap of the one or more measurement gaps. The UE performs measurements of PRSs within the one measurement gap.

    Abstract: Apparatus and methods are provided to support SRB0 transmission for L2 UE-to-NW relay. In one novel aspect, the SRB0 message includes remote UE ID by the remote UE or relay UE during forwarding the SRB message. In one novel aspect, when perform SRB0 transmission over PC5 interface, the relay UE and remote UE apply default bearer/default RLC channel for SRB0 transmission. In one novel aspect, the relay UE and base station exchange the forwarded UL SRB0 message and DL SRB0 message via contained of RRC message over UL-DCCH and DL-DCCH separately. In one novel aspect, the message in response to the transmission of SRB0 from the remote UE further includes C-RNTI for the remote UE if this remote UE is initiating RRC Setup or RRC Resume procedure.
