Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing unified RACH for multiple features. For example, some aspects of this disclosure relate to a method including determining, by a user equipment (UE), a feature to be indicated at an initial access of the UE to a base station and determining whether the UE and the base station support feature specific random access (RA) procedure for the feature. The method further includes determining whether a condition for the feature is satisfied in response to determining that both the UE and the base station support the feature specific RA procedure for the feature. In response to determining that the condition is satisfied, the method includes selecting a feature specific Random Access Channel (RACH) resource and perform a 4-step RA procedure or a 2-step RA procedure based on the selected feature specific RACH resource.

Abstract: Disclosed are embodiments for authentication and authorization in a 5G network between an edge enabler client (EEC) of a UE and an edge configuration server (ECS). The embodiment include performing primary authentication with the 5G network to obtain a KAUSF; generating a Kedge and a Kedge ID using the KAUSF and a subscription permanent identifier (SUPI); providing the Kedge and the Kedge ID to the EEC to cause it to compute a MACEEC using the Kedge and an EEC ID; and sending to the ECS an application registration request, the application registration request including the EEC ID, MACEEC, and Kedge ID.

Abstract: A method, user equipment (UE) and integrated circuit for receiving data transmitted over a wireless network. The method includes executing an application that receives data from the network, transmitting UE assistance information to the network, wherein the UE assistance information corresponds to a traffic pattern for the data that is received from the network for the application, entering a radio resource control (RRC) inactive state and receiving the data from the network while in the RRC inactive state.

Abstract: The exemplary embodiments relate to a user equipment (UE) delivering an indication of one or more uplink listen-before-talk (LBT) failures to a network. The UE may identify a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell). The UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition. Next, the UE may determine a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network. The UE may transmit the type of message including the indication of uplink LBT failure associated with the SpCell to the network. Subsequently, the UE may determine that the network received the indication of uplink LBT failure associated with the SpCell.

Abstract: Some aspects include an apparatus, method, and computer program product for facilitating control messaging for multi-beam communications in 5G wireless communication systems. Nodes of a 5G network may be generate Medium Access Control Control Elements (MAC CEs) to update User Equipment (UE) with different Component Carrier (CC) settings. The MAC CEs may update a list of CCs to reduce messaging overhead and latency. For example, a MAC CE may indicate an update for a Transmission Configuration Indication (TCI) state for a list of CCs. Similarly, a MAC CE may be used to update a spatial relation for a Sounding Reference Signal (SRS) resource set and/or a SRS resource corresponding to a list of CCs. A MAC CE may also be used to update multiple TCI codepoints having one or two TCI states in a multi-Transmission Reception Point (multi-TRP) scenario.

Abstract: A method performed by a user equipment (UE) configured with an uplink and a sidelink. The method includes determining that a first set of data is to be transmitted in the uplink, assigning a priority value to the first set of data, determining that a second set of data is to be transmitted in the sidelink, assigning a priority value to the second set of data, determining that the first and second set of data are to be transmitted using a same resource at a same time, selecting one of the first set of data or the second set of data to be transmitted first based on at least the first priority value and the second priority value and when the first set of data that is to be transmitted in the uplink is selected, transmitting the first set of data prior to transmitting the second set of data.

Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.
