An apparatus and a method for allocating wireless channels are disclosed. For example, the method, by an aggregator, aggregates sensed information received from a plurality of sensing devices, by an analyzer, analyzes the sensed information that is aggregated and determines when an incumbent is not detected based on the analysis, and allocates, by a channel allocator, a wireless channel of the targeted frequency spectrum to a user equipment when the incumbent is not detected.

Embodiments of the present disclosure relate to a method for transmitting sidelink data, a terminal device and a non-transitory computer-readable storage medium. The method includes obtaining, by a terminal device, first configuration information; and obtaining, by the terminal device, second configuration information. The first configuration information is used to indicate to transmit a first sidelink transmission channel on a target transmission resource. The second configuration information is used to transmit a second sidelink transmission channel on the target transmission resource. The method further includes sending, by the terminal device, the first sidelink transmission channel or the second sidelink transmission channel on the target transmission resource according to a preset rule.

The disclosure provides an augmented reality (AR) information transmission system and an AR information transmission method. The AR information transmission system includes a wireless information transmission device. The wireless information transmission device includes a directivity transmitter and a processor. The processor is configured to: obtain AR information and convert the AR information into a wireless signal; and control the directivity transmitter to send the wireless signal toward a designated direction.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure on a secondary cell (SCell), wherein the UE is configured with a primary cell (PCell) and the SCell for carrier aggregation with a base station; identify an order in which multiple procedures for transmitting a beam failure recovery request are to be attempted, wherein the multiple procedures include at least one of: a procedure for transmitting the beam failure recovery request via the PCell, a procedure for transmitting the beam failure recovery request via one or more SCells configured for the UE, or a combination thereof; and transmit the beam failure recovery request to the base station using a first procedure, of the multiple procedures, based at least in part on the order. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. For instance, a UE or base station may identify a first portion of a payload associated with a first priority and a second portion of the payload associated with a second priority less than the first priority. The UE or base station may select a first matrix associated with a first domain for the first portion of the payload and a second matrix associated with a second domain for the second portion of the payload based on a first maximum index interval for the first matrix being larger than a second maximum index interval for the second matrix. The UE may transmit or the base station may receive the first portion of the payload using one or more sequences associated with the first matrix and the second portion of the payload using one or more sequences associated with the second matrix.

Embodiments herein provide a user equipment (UE) and a method for performing communication in a mission critical services (MCX) off-network. The method includes: sending an announcement message for a slot reservation for a complete scheduling assignment (SA) cycle; determining whether a second UE in the MCX Off-network is trying to reserve same slot and having a higher priority than priority of the first UE. Further, the method includes performing one of: backing off and sending a new announcement message for the slot reservation in response to determining that the second UE is trying to reserve a same slot and has the higher priority than the priority of the first UE, and reserving the same slot in response to determining that the second UE is trying to reserve the same slot and the second UE has a lower priority than the priority of the first UE.

Provided is a wireless communication terminal wirelessly communicating with a base wireless communication terminal. The wireless communication terminal comprises a transceiver and the processor. The processer receives, by using the transceiver, a wireless signal including a trigger frame from the base wireless communication terminal and transmits, by using the transceiver, buffer status information to the base wireless communication terminal based on the trigger frame. The buffer status information is included in a QoS control field which signals information on a QoS control of a MAC header.

The method includes: obtaining, by UE, UE capability information of the UE; if the size of the UE capability information exceeds the maximum tolerance that can be processed by the PDCP layer of the UE, splitting the UE capability information into at least two pieces of part UE capability information, where each piece does not exceed the maximum tolerance that can be processed by the PDCP layer; and reporting at least one piece of part UE capability information to a network side device. According to this method, the UE capability information is split on a UE side, and reported to the network side device for a plurality of times.

Methods, systems, and apparatuses for sidelink communication are disclosed. A WTRU may receive a first SCI element from a second WTRU within a group. The WTRU may receive a first RCI element within a first set of resources scheduled by the first SCI. The first RCI may include information about which WTRU in the group is scheduled to use a second set of resources. The WTRU may determine, based on the first RCI, that one or more subresources within the second set of resources are available. The WTRU may transmit data in the one or more subresources. The first SCI and the first RCI may be received in a first reservation period and the one or more subresources may be in a second reservation period.

A method and an apparatus for monitoring a downlink control channel, a terminal device, and a computer readable storage medium. The monitoring method includes determining, by a terminal device, priority information, where the priority information includes at least one of a control resource set priority, a search space priority, a downlink control information priority, or a downlink control information size priority, monitoring, by the terminal device, a downlink control channel based on the priority information, and obtaining, by the terminal device, downlink control information from the downlink control channel.
