Sidelink collision avoidance, HARQ feedback, and CSI acquisition

A computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE). configure the UE for NR communication. The instructions cause the UE to decode sidelink control information (SCI). The SCI includes scheduling information and priority information. The scheduling information indicates time resource assignment and frequency resource assignment for sidelink data communications using a physical sidelink shared channel (PSSCH). The instructions further cause the UE to detect that a transmission (Tx) of a first set of physical sidelink feedback channels (PSFCHs) would overlap in time with a reception (Rx) of a second set of PSFCHs. The first and second sets of PSFCHs include sidelink feedback control information for the sidelink data communications. The instructions further cause transmission of at least one PSFCH from the first set of PSFCHs or the second set of PSFCHs based on the priority information.

20230232201 · 2023-07-20 · ·

Embodiments of the present disclosure provide for sidelink communications. In a method for communications, a first terminal device receives information about an identity related to a relay feature of at least one second terminal device via a sidelink channel. The first terminal device determines a relay terminal device of the first terminal device based on the information about the identity. Embodiments of the present disclosure provides a more flexible and feasible communication mechanism for relay discovery and selection without requirements for a specific resource pool for sidelink discovery or performing cyclic redundancy check on resources of the sidelink channel. The identity dedicated to the relay feature can not only be used to distinguish different terminal devices but also enable the terminal device to determine whether they are to be discovered as a candidate relay terminal device by the remote terminal device, and thereby enhancing the relay discovery and selection procedure.

Datapath load distribution for a RIC
11704148 · 2023-07-18 · ·

To provide a low latency near RT RIC, some embodiments separate the RIC's functions into several different components that operate on different machines (e.g., execute on VMs or Pods) operating on the same host computer or different host computers. Some embodiments also provide high speed interfaces between these machines. Some or all of these interfaces operate in non-blocking, lockless manner in order to ensure that critical near RT RIC operations (e.g., datapath processes) are not delayed due to multiple requests causing one or more components to stall. In addition, each of these RIC components also has an internal architecture that is designed to operate in a non-blocking manner so that no one process of a component can block the operation of another process of the component. All of these low latency features allow the near RT RIC to serve as a high speed IO between the E2 nodes and the xApps.

Aspects of the disclosure relate to control of discovery signal transmissions for D2D communication. A first UE may transmit a discovery signal initiation message to at least a second UE to control transmission of a discovery signal from the second UE to a third UE. The second UE may identify a discovery signal monitoring duration of the second UE during which the second UE monitors for transmitted discovery signals transmitted from other UEs to the third UE. At expiration of the discovery signal monitoring duration, the second UE may transmit a discovery signal to the third UE when the number of transmitted discovery signals transmitted from the other UEs during the discovery signal monitoring duration is less than a discovery signal transmission number threshold.

Dynamic mapping of nodes responsible for monitoring traffic of an evolved packet core

Introduced here are visibility platforms able to process the traffic handled by the gateways of an Evolved Packet Core (EPC) with Control and User Plane Separation (CUPS). A visibility platform can include a control processing node (CPN) and one or more user processing nodes (UPNs). The visibility platform may populate a data structure in which the CPN and UPNs are associated with locations along an interface on which Sx/N4 traffic is exchanged between the control and user planes. Each location may be representative of the point on the Sx/N4 interface at which Sx/N4 traffic processed by the corresponding node is acquired. The CPN can use the data structure to program session flows that impact how user traffic is handled by the UPNs.

Ethernet bridging in SDN-based wireless mesh networks
