Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may distinguish between synchronization signal blocks (SSBs) intended for different classes of UEs. For example, a base station may transmit different SSBs in a physical broadcast channel with different configurations or parameters to indicate different UE classes, where UEs may monitor for and receive SSBs for their UE class. A UE may operate according to a UE class (e.g., New Radio (NR) Light) associated with lower bandwidths and may identify SSBs associated with this UE class to connect with a base station. The UE may identify the SSBs associated with the UE class based on a subcarrier-level offset value either implicitly or explicitly indicated to the UE. Additionally, the base station may transmit fields to indicate different parameters for subsequent communications transmitted according to the UE class.

Abstract: The invention relates to a method for transmitting a periodic channel quality report (CSI) and/or a sounding reference symbol (SRS) from a UE to an eNodeB. To avoid double decoding at the eNodeB in transient phases, a deterministic behavior of the UE is defined by the invention, according to which the eNodeB can unambiguously determine whether the UE will transmit the CSI/SRS or not. According to one embodiment, the UL grants and/or DL assignments received until and including subframe N?4 only are considered; UL grants and/or DL assignments received by the UE after subframe N?4 are discarded for the determination. Additionally, DRX-related timers at subframe N?4 are considered for the determination. In a second embodiment, DRX MAC control elements from the eNodeB, instructing the UE to enter DRX, i.e., become Non-Active, are only considered for the determination if they are received before subframe N?4, i.e., until and including subframe N?(4+k).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, for a sidelink transmission over an unlicensed band and associated with a medium access control (MAC) protocol data unit (PDU), one or more candidate resources of a set of candidate resources that are within an adaptive effective contention window (ECW). The UE may adjust at least one parameter of the adaptive ECW to determine an adjusted at least one parameter based at least in part on a channel access output associated with the one or more candidate resources. The UE may transmit the MAC PDU using the one or more candidate resources or an additional one or more candidate resources, wherein the additional one or more candidate resources are selected based at least in part on the adjusted at least one parameter. Numerous other aspects are provided.

Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

Hence, activation or deactivation may be performed on the duplication transmission mode of one or more PDCP entities in the user equipment.

Abstract: In an adaptive route wireless network and bi-directional protocol, each computing device along a route to a gateway appends the previous node's network address to downstream messages as they are transmitted along the route from an originating computing device to the gateway. The list of appended network addresses thus records the route taken by the downstream network message through the adaptive route network. A server computing device maintains a route table including the list of appended network addresses received with each downstream message. To send unsolicited upstream messages to any computing device on the wireless network, the server generates an upstream network message that includes the appended network address(es) from the portion of the route table corresponding to the destination computing device. The upstream route to the destination computing device is thus contained in the list of appended network addresses within the network message.

Abstract: Techniques described herein provide for fast updating of a forwarding table in a single active multihoming configuration. A first network device that is not connected to an ethernet segment (ES), receives a plurality of ethernet segment (ES) routes (e.g., EVPN type-4 routes) from a plurality of network devices that are connected to a host via the ES. When connectivity is lost to the on a designated forwarded for the ES, t the first network device performed a designated forwarding election algorithm based on the plurality of the received ES routes, to identify that a second network device of the plurality of network devices is designated as a new forwarding device. The first network device modifies an entry in a forwarding table to indicate that the host is now reachable via the second network device.
