Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message that includes a frequency domain resource allocation field to indicate allocated resource blocks (RBs) across multiple transmission configuration indication (TCI) states. The UE may identify, based at least in part on the DCI message and/or a radio resource control configuration, at least one parameter that indicates a unit of contiguous RBs over which the same precoding is used and/or a resource allocation type. The UE may assign the allocated RBs to individual TCI states among the multiple TCI states based at least in part on the unit of contiguous RBs over which the same precoding is used and/or the resource allocation type. Numerous other aspects are provided.

When the edge SE receives network data with a destination address in the second domain, it forwards the network data directly to the interconnection SE.

Abstract: In a channel occupancy time (COT), a scheduling entity can transmit a first downlink (DL) transmission burst to a scheduled entity, and receive an uplink (UL) transmission burst from the scheduled entity. The scheduling entity can determine whether the scheduled entity performed a type 1 or type 2 channel access procedure for the UL transmission burst. A scheduled entity can use a first type of channel access procedure to initiate a first COT on a communication channel and request a network access node to perform a second type of channel access procedure in a next DL transmission burst. A network access node can receive a message from a scheduled entity, wherein the message comprises a control indication requesting the network access node to perform a first type of channel access procedure in a next DL transmission burst.

Abstract: When initiating a Voice-over-IP (VoIP) communication session between an originating device (MO) and a terminating device (MT) on a packet-switched network, network components associated with the MO may encounter a failure when preparing resources for the session, such as a failure to establish a dedicated bearer with the MO. This might typically cause the system to abort the session. Instead, the network components are configured to detect the failure and to initiate a handover to a circuit-switched communication network so that the session may be conducted through the circuit-switched communication network. The failure may be detected by a component of a Long-Term Evolution (LTE) Radio Access Network (RAN) of the network, by a Mobility Management Entity (MME) of the network, or by some other network component. Single Radio Voice Call Continuity (SRVCC) procedures may be used to implement the handover.

Abstract: Techniques and mechanisms for Fifth Generation (5G) system (5GS) failure detection monitoring of an application or control function in a network for efficient restoration of service are described. The network may be an Internet Protocol (IP) Multimedia Subsystem (IMS) network, and the voice or data service may be an IMS service that utilizes Session Initiation Protocol (SIP) signaling. The application or control function may be a Proxy-Call Session Control Function (P-CSCF) of the IMS network. In some implementations, the procedure may involve a session management function (SMF) programming of a user plane function (UPF) for UPF monitoring of the P-CSCF, using a ping procedure or health check procedure (e.g. for 3GPP Pre-Release 16). In other implementations, the procedure may involve the SMF monitoring of a P-CSCF via a Network Function (NF) Repository Function (NRF) (e.g. for 3GPP Release 16).

Abstract: Some embodiments of the invention provide a method for network-aware load balancing for data messages traversing a software-defined wide area network (SD-WAN) (e.g., a virtual network) including multiple connection links between different elements of the SD-WAN. The method includes receiving, at a load balancer in a multi-machine site, link state data relating to a set of SD-WAN datapaths including connection links of the multiple connection links. The load balancer, in some embodiments, provides load balancing for data messages sent from a machine in the multi-machine site to a set of destination machines (e.g., web servers, database servers, etc.) connected to the load balancer over the set of SD-WAN datapaths. The load balancer selects, for the data message, a particular destination machine (e.g., a frontend machine for a set of backend servers) in the set of destination machines by performing a load balancing operation based on the received link state data.

Abstract: A phased array antenna system that reduces the high number of active elements and complexity. In order to achieve this reduction, the RF chain is designed for summation of all radiators in a single row. This reduces the hardware complexity from N2 to N where the array size is N×N. This reduction allows the antenna to electronically steer in one axis. The other axis is mechanically steered using a rotating platform. The loss between the LNA or PA with the row summation scheme is very low resulting in very high performance. Receiving and transmitting take place from the same aperture.
