Systems and methods are for securing link aggregation are provided. According to an embodiment, a network device in a secure domain discovers device information associated with a peer network device in an untrusted domain that is connected through a first link directly connecting a first interface of the network device to a first interface of the peer network device, and authenticates the peer while allowing at least some network traffic to continue to be transmitted through the first interface. The network device establishes a secure session between the network device and the peer over the first link when the peer network device is successfully authenticated. The network device then allows the first link to operate as part of a single aggregated logical link, including a second link coupling a second interface of the network device to a second interface of the peer network device.

Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may communicate with one or more other UEs in accordance with a distributed resource allocation mode. To select suitable resources for an intended sidelink transmission, the first UE may transmit, to a second UE, a request for a type of coordination information based on information associated with the intended sidelink transmission from the first UE. The second UE may generate coordination information in accordance with the requested type and may transmit the coordination information to the first UE. The first UE may use the coordination information to select a set of resources over which to perform the intended sidelink transmission from the first UE and may perform the intended sidelink transmission over the selected set of resources.

A user equipment includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to: select radio resources for a first sidelink transmission to a first user equipment based on sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment; and perform the first sidelink transmission to the first user equipment on the selected radio resources.

A computer-implemented method for selectively excluding data from compression prior to uplink to a telecommunication system. In an embodiment, the method analyzing a request by an application, executing within a device, to wirelessly uplink data to a telecommunication node. The method further includes establishing a set of logical channels assigned to the application. The method further includes transferring the data among one or more logical channels, of the set of logical channels, based on a status flag related to data compression corresponding to the data. The method further includes determining that the data is transferred via a compression-disabled logical channel, of the set of logical channels. The method further includes responding to determining that the data is transferred via the compression-disabled logical channel by bypassing a data compression function prior to preparing the data for uplink. The method further includes uplinking the data to the telecommunication node.

Some aspects of this disclosure relate to apparatuses and methods for a user equipment (UE) to send a portion of a packet data unit (PDU) to a base station. A radio link control (RLC) layer of the UE generates a PDU and a truncation indicator, where the truncation indicator can indicate a set of truncation points of the PDU. A medium access control (MAC) layer determines whether an uplink transmission size based on an uplink grant is smaller than a first number of bytes included in the PDU. In response to a determination that the uplink transmission size is smaller than the first number of bytes, the MAC layer selects a truncation point from the set of truncation points indicated by the truncation indicator, and remove at least a portion of the PDU to generate a truncated PDU having a second number of bytes smaller than the uplink transmission size.

A first base station central unit (BS-CU) communicates, with one or more wireless devices, packets via a first cell operating in an unlicensed spectrum. The BS-CU receives, from a first base station distributed unit (BS-DU), a channel occupancy ratio (CR) of the first cell, wherein the CR is for a plurality of time intervals and indicates utilization of unlicensed channel resources that have been utilized for transmissions by the first cell. The BS-CU transmits, to a second base station, the CR.
