An embodiment relates to a method for a first terminal operating in a wireless communication system, the method comprising the steps of: transmitting application information from an application layer to a vehicle-to-everything (V2X) layer; generating, in the V2X layer, sidelink (SL) discontinuous reception (DRX) information on the basis of the application information; transmitting the SL DRX information from the V2X layer to an AS layer; and communicating with a second terminal by applying the SL DRX information in the AS layer, wherein the application information includes at least one application requirement.

Apparatuses, methods, and systems are disclosed for transmitting and/or receiving system information for changing a configuration. One apparatus includes a receiver that: receives first system information for a first configuration; and receives second system information for a second configuration based on the first configuration. The second system information includes changes to the first configuration without repeating information common to the first and second configurations.

Apparatuses, methods, and systems are disclosed for transmitting and/or receiving system information for changing a configuration. One apparatus includes a receiver that: receives first system information for a first configuration; and receives second system information for a second configuration based on the first configuration. The second system information includes changes to the first configuration without repeating information common to the first and second configurations.

In embodiments of the present disclosure, a method is provided for performing a frame processing operation on a broadcast/multicast frame at a physical access point (AP). A pre-processing operation is performed on the frame at a protocol layer between a physical layer and an upper layer of the AP to obtain a pre-processed frame. The pre-processing operation comprises a common operation to be performed for the plurality of virtual interfaces at the protocol layer. In this way, by performing a pre-processing operation common to the virtual interfaces supported by the physical AP, the consumption of resources caused by the performance of repeated operations in the frame processing operation can be reduced.

There is provided a communication apparatus comprising: one or more processors; and one or more memories storing instructions that, when executed by the one or more processors, cause the communication apparatus to: generate capability information about a method of a plurality of primary channels (M-PCH) compliant with the IEEE 802.11 series; and transmit a frame including the capability information to a communication partner apparatus, wherein the capability information includes at least one of information representing whether the plurality of communication apparatus supports the M-PCH method, and information representing availability of each of the primary channels.

In one embodiment, a method is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. The mobile communication device requests activation of a data session with a node via the wireless network and receives a reject message via the wireless network in response to the request for activation of the data session, the reject message including a cause code. If the cause code corresponds to a no-retry behavior of the data session retry mechanism of the mobile communication device, the mobile communications device no longer requesting activation of a data session with the node.

Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

A method for concurrent execution of multiple protocols using a single radio of a wireless communication device is provided that includes receiving, in a radio command scheduler, a first radio command from a first protocol stack of a plurality of protocol states executing on the wireless communication device, determining a scheduling policy for the first radio command based on a current state of each protocol stack of the plurality of protocol stacks, and scheduling the first radio command in a radio command queue for the radio based on the scheduling policy, wherein the radio command scheduler uses the radio command queue to schedule radio commands received from the plurality of protocol stacks.

An electronic device according to various example embodiments includes: at least one wireless communication module comprising wireless communication circuitry configured to support a first communication protocol and a second communication protocol, at least one processor operatively connected to the wireless communication module, and a memory electrically connected to the processor and configured to store instructions executable by the processor. When the instructions are executed by the processor, the processor may, using the wireless communication module, set a schedule for a first data link that uses a first frequency band as the second communication protocol with a first external electronic device, set a schedule for a second data link that uses a second frequency band as the second communication protocol with a second external electronic device, and change the second data link to a third data link that uses a third frequency band and perform communication with the second external electronic device, based on the third frequency band being available due to a termination of the first data link.

Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.
