The present disclosure generally discloses an autonomous wireless transmission mechanism. The autonomous wireless transmission mechanism may be configured to support autonomous transmissions by wireless end devices to wireless access nodes in a connectionless manner. In general, an autonomous wireless transmission by a wireless end device may include transmission of a preamble in a preamble transmission zone and autonomous transmission of a payload over one or more resource units of one or more payload transmission zones without requiring establishment of a connection between the wireless end device and the wireless access node. The autonomous wireless transmission mechanism, by obviating the need for a wireless end device to establish a connection with a wireless access node in order to transmit data to the wireless access node, also obviates a need for the wireless end device to operate in a scheduled transmission mode.

A system, apparatus, method, and non-transitory computer readable medium for providing transfer block indications in uplink (UL) grant-free transmissions may include a memory having computer readable instructions stored thereon, and at least one processor configured to execute the computer readable instructions to transmit a first transport block (TB) to a base station (BS) during a first transmission time interval (TTI) using a grant-free UL transmission, receive a UL grant from the BS in a physical downlink control channel (PDCCH) region during a time window, determine a target of the UL grant, the target including at least one of the first TB, a second TB, or a previously transmitted TB, based on the UL grant, and transmitting the target of the UL grant to the BS.

Various methods and devices are provided to address the need for improved dual connectivity. For example, a network node () in a primary network includes a processing unit () and an interface unit (), which includes a network interface () for communication with other network devices. The processing unit is communicatively coupled to the interface unit and configured to receive, from a user equipment (UE) via the interface unit, a secondary Internet Protocol (IP) address for the UE, the secondary IP address being associated with a secondary network of the UE. The processing unit is also configured to initiate via the interface unit the establishment of at least one tunnel to bridge the network node and the UE via the secondary network.

Embodiments are described herein to provide improvements to known network interference cancellation techniques. One general approach involves a first network node attempting () to decode a received signal which includes signaling from a first wireless device transmission and at least one interfering transmission. If the first network node is unsuccessful in attempting to decode the received signal, it is determined () whether it would be cost effective to obtain decoded signaling from a serving network node of a wireless device that corresponds to the at least one interfering transmission. If () it is determined to be cost effective, the decoded signaling that corresponds to the at least one interfering transmission is requested.

In one method, an anchor-cell transceiver node communicates with a mobile device via a primary link. The anchor-cell transceiver node conveys information for the mobile device to the mobile device by routing at least a portion of the information to the mobile device via a secondary-cell transceiver node.

Various methods and apparatuses are provided to address the need for improved multi-carrier communication. In one apparatus, a radio access network (RAN) () includes multiple network nodes () operative to transmit, via multiple carriers (-), packet data to a user element (UE) () using a protocol stack. The protocol stack includes a radio link control (RLC) layer split into an upper RLC processing layer and multiple lower RLC processing layers. Each lower RLC processing layer is associated with one carrier of the multiple carriers and each lower RLC processing layer supports packet data transmission via its associated carrier. The upper RLC processing layer supports packet data transmission via the multiple carriers.
