Wireless communications systems and methods related to updating control information based on medium sensing are provided. A first wireless communication device communicates with a second wireless communication device, a first transmission grant for a transmission opportunity (TXOP) in a frequency band. The first wireless communication device performs medium sensing for the TXOP. The performing the medium sensing includes detecting a reservation signal for the TXOP. The first wireless communication device transmits, to the second wireless communication device, an updated transmission grant for the TXOP based on at least the first transmission grant and the medium sensing.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a control resource set (CORESET), wherein the configuration includes an indication that the CORESET is a single frequency network (SFN) CORESET. The UE may determine one or more transmission configuration indicator (TCI) states for monitoring the SFN CORESET based at least in part on a determination that the UE has not received an activation command that indicates multiple TCI states to be activated. The UE may receive a physical downlink control channel (PDCCH) communication using the one or more TCI states determined for monitoring the SFN CORESET. Numerous other aspects are described.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present application discloses a transmission method and device. According to an aspect of the present application, there is provided a transmission method performed by a user equipment (UE). The method includes: receiving resource configuration information from a base station; determining valid transmission occasions from transmission occasions based on the resource configuration information; performing random access at the valid transmission occasions, wherein the resource configuration information received from the base station contains time-domain and frequency-domain uplink and downlink transmission resource information.

A communication circuit and protocol for a wireless local area network (WLAN) using single EDCA and/or Multiple-User (MU) EDCA in which frames for Real Time Applications (RTA) can utilize shared Transmit Opportunities (TXOPs) to reduce transmission latencies. The protocol is configured in a number of ways to ensure communication fairness, such as by ensuring a minimum required channel resource is provided for transmitting frames from the primary AC during the TXOP. AP MLDs and non-AP MLDs are also supported and can exchange information on distinguishing traffic streams from other traffic streams having the same Traffic Identifier (TID), in determining which links to use for transmitting the traffic stream.

Methods and apparatuses for a User Equipment (UE) to monitor the Physical Downlink Control Channel (PDCCH) appropriately in order to reduce power consumption and perform Contention Resolution for a Random Access (RA) procedure in a Non-Terrestrial Network (NTN). The UE can perform a Msg3 transmission during a RA procedure in a NTN and start a RA contention resolution timer in the first symbol after the end of the Msg3 transmission plus a timing offset. In response to expiry of the RA contention resolution timer, the UE determines whether to consider Contention Resolution not successful based on at least whether the RA contention resolution timer expires during a time duration of the timing offset after a Msg3 retransmission.

A transmission control method, a transmission control apparatus, and a communication device are provided. A transmission control method, performed by a communication device, includes: canceling, in a case that a Request-To-Send (RTS) message or a Clear-To-Send (CTS) message meets a preset condition, configured transmission.

Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A base station can poll user equipment (UE) by transmitting a downlink control information (DCI) or other downlink communication that indicates resources that a UE can use to send a scheduling request. The resources are dynamic, e.g., they can be updated and allocated to UEs based on network conditions. Other aspects are described.

A wireless communication method of a first device with a second device using multiple links, including first and second links, the method including obtaining transmission-related information in response to entering a transmission preparation period of a first request-to-send (RTS) frame through the first link, the transmission-related information corresponding to a second RTS frame associated with the second link, determining at least one of an additional length or cross-link-related information of the first RTS frame based on the transmission-related information, and determining whether to transmit the second RTS frame based on the at least one of the additional length of the cross-link-related information of the first RTS frame.

A wireless communication method performed by a first device includes entering a transmission preparation period of a first Request To Send (RTS) frame via a first link; obtaining transmission-related information of a second RTS frame via a second link; determining at least one of a first transmission timing and content of the first RTS frame, based on the transmission-related information of the second RTS frame; generating the first RTS frame based on a result of the determining; and transmitting, to a second device via the first link, the generated first RTS frame.

A method by a network node in a wireless communication network includes buffering first data for downlink transmission to a first wireless device, and preemptively transmitting the first data on a channel that is subject to clear channel assessment procedures. The first data is transmitted in a reference downlink resource (RDR) domain in the channel in which second data for a second wireless device was previously scheduled for transmission by the network node. The method further includes transmitting a preemption indicator to the second wireless device, the preemption indicator identifying the RDR domain. Related network nodes, methods of operating a wireless device, and wireless devices are also disclosed.
