According to one embodiment of the disclosure, a method by which a first device performs SL communication is provided. The method can comprise the steps of: generating, in a MAC CE form, SL CSI related to a channel state between a first device and a second device in a MAC layer; transmitting, to a base station, a first SR triggered on the basis of the SL CSI having the MAC CE form; receiving an SL grant from the base station; and transmitting, to the second device, the SL CSI on an SL resource related to the SL grant.

Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

A method performed by a wireless device is described herein. The wireless device operates in a wireless communications network. The wireless device provides a message to be sent to a network node operating in the wireless communications network. The message is a first scheduled message to be sent to the network node in a random access procedure. The message comprises a first indicator of a type of the message. The type of message has: a) a fixed size SDU, and b) a one byte header comprising the first indicator and lacking a second indicator of a length of a payload. The wireless device also initiates sending the provided message to the network node. Also described is a method performed by the network node receiving and initiating processing the message, based on the first indicator.

A terminal according to an aspect of the present disclosure includes: a receiving section that receives information relating to an uplink signal; and a control section that uses, when medium access control (MAC) control element (CE) is indicated and the information satisfies an applicable condition, a specific spatial relation based on the MAC CE for transmitting the uplink signal instead of a spatial relation indicated for the uplink signal. According to an aspect of the present disclosure, QCL parameters can be appropriately determined.

The disclosure relates to a communication technique for combining, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and to a system therefor. The disclosure may be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.), based on a 5.sup.th generation (5G) communication technology and an Internet of Things (IoT)-related technology. The disclosure discloses a method and an apparatus for providing direct communication services.
