Abstract: A method for increasing stability of an inter-channel time difference (ICTD) parameter in parametric audio coding, wherein a multi-channel audio input signal comprising at least two channels is received. The method comprises obtaining an ICTD estimate, ICT Dest(m), for an audio frame m and a stability estimate of said ICTD estimate, and determining whether the obtained ICTD estimate, ICT Dest(m), is valid. If the ICTDest(m) is not found valid, and a determined sufficient number of valid ICTD estimates have been found in preceding frames, a hang-over time is determined using the stability estimate and a previously obtained valid ICTD parameter, ICTD(m?1), is selected as an output parameter, ICTD(m), during the hang-over time. The output parameter, ICTD(m), is set to zero if valid ICT Dest(m) is not found during the hang-over time.

Abstract: Exemplary embodiments include methods for a user equipment (UE) to receive a wake-up signal (WUS) via downlink control information (DCI) transmitted by a network node in a radio access network (RAN). Such methods include receiving a physical downlink control channel (PDCCH) from the network node, and processing the received PDCCH to determine if it includes a DCI carrying a WUS targeted to the UE. The processing can include determining if a payload portion of the DCI is based on a first function of an identifier associated with the UE (e.g., C-RNTI) or with a group of UEs (e.g., WUG-RNTI). The processing can also include determining if a cyclic redundancy check (CRC) portion of the DCI is based on a second function of the identifier. Other embodiments include complementary methods performed by a network node, and UEs or network nodes configured to perform the exemplary methods.

Abstract: Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe.

Abstract: Secure, authenticated communication is enabled between an initiator (12) (e.g., a user equipment) and a responder (14) (e.g., an authentication server function, AUSF, or a subscription de-concealing function, SIDF). The initiator (12) transmits a message (20) to the responder (14) over a secure communication channel (16).

The responder (14) correspondingly retrieves from the third party (18) data that is signed by the third party (18) and transmits a response (24) to the initiator (12) that includes the retrieved data. The initiator (12) receives this response (24) and determines whether or not the responder (14) is authenticated by determining whether or not the response (24) includes data that is signed by the third party (18).
