Abstract: A transport path group for uplink transmission over a fronthaul interface. The transport path group may include (i) an address of a first source port of a radio unit (RU), (ii) an address of a first destination port of a distributed unit (DU), and (iii) an address of a second source port of the RU, an address of a second destination port of the DU, and/or a flow identifier (e.g., a virtualized local area network (VLAN)). A request for user data conveyed by the DU and received by the RU may identify the transport path group. The RU may use the fronthaul interface to convey to the DU first and second portions of the requested user data over first and second different paths from the RU to the DU. The RU may employ load balancing parameters to convey the first and second portions of the requested user data.

Abstract: A system for multicast packet management in a first switch in an overlay tunnel fabric is provided. The system can operate the first switch as part of a virtual switch in conjunction with a second switch of the fabric. The virtual switch can operate as a gateway for the fabric. During operation, the system can receive a join request for a multicast group. The system can then determine whether to forward the join request to the second switch based on a type of a first ingress connection of the join request. Upon receiving a data packet for the multicast group, the system can determine how to forward the data packet based on respective types of a second ingress connection and an egress connection of the data packet. The type of a respective connection can indicate whether the connection includes an overlay tunnel.

Abstract: Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.

Abstract: A method for switching frequency band in a mesh network including a plurality of access points is provided. The method includes turning off one of two communication ports of a second backhaul station of an idle node when the idle node is in an on-boarding phase and the two communication ports are turned on, so that the idle node joins the mesh network by communicatively connecting to a first backhaul station of one of the access points through the turned on communication port. The two communication ports operate in different frequency bands. A first fronthaul station of each of the access points is configured to provide a communication connection for at least one user terminal. A second fronthaul station of the idle node is configured to provide a communication connection for the at least one user terminal after the idle node joins the mesh network.

Abstract: A statistical multiplexer is provided with a series of encoders that encode media streams at different bitrates to reduce jitter. The encoded media streams are transmitted to a multiplexer over a network and experience jitter that is reduced by a de-jitter arrangement. The multiplexer rearranges a transmit time of select packets in select ones of the media streams received over the network when a total group bandwidth available on the transmission channel over which the multiplexed media stream is to be transmitted is less than a sum of the bandwidths of the media streams because of the jitter and de-jitter process experienced by the media streams. The rearranging causes the bandwidth of the multiplexed media stream to be no greater than the total group bandwidth of the transmission channel without exceeding a maximum bit rate at which each individual encoded media stream is configured.

Abstract: This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve a desired amplitude distribution. Some implementations more specifically relate to performing an encoding operation to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some implementations of the non-uniform distribution, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. Some implementations enable the tracking of MPDU boundaries to facilitate successful decoding by a receiving device. Additionally or alternatively, some implementations enable the determination of a packet length after performing the amplitude shaping, which enables a transmitting device to determine the number of padding bits to add to the payload and to signal the packet length to a receiving device so that the receiving device may determine the duration of the packet.

Abstract: With increasingly dense wireless traffic in 5G and 6G networks, the incidence of message faults due to interference is increasing, leading to wasted time and energy on multiple re-transmissions. Disclosed are procedures for assembling a fault-free copy of a message from two corrupted copies. First, measure the modulation quality of each message element. A faulted message element usually has poor modulation quality. Then, select the best message elements from each of the two corrupted copies, and test the merged version against an embedded error-detection code. If the merged copy still fails the test, select each of the message elements that are different in the two faulted copies since they are all suspicious, and test each version with the error-detection code. By recovering a message despite reception errors, another transmission is avoided, saving time and energy, and avoiding contributing yet further to the background noise. Many additional aspects are disclosed.
