Methods and apparatuses for a sidelink synchronization signals and physical sidelink broadcast channel block (S-SS/PSBCH) block structure for unlicensed operation. A method of a user equipment (UE) in a wireless communication system includes determining a subcarrier spacing (SCS) of a sidelink synchronization signals and physical sidelink broadcast channel (S-SS/PSBCH) block; determining a set of interlaced resource blocks (RBs). The set of interlaced RBs includes RBs with a uniform interval k. The method further includes mapping the S-SS/PSBCH block to the set of interlaced RBs and transmitting, to another UE, the S-SS/PSBCH block over a sidelink channel.

Provided is a method for indicating a resource, including: indicating, in a configured time-frequency resource region, a time-frequency resource of a service with first transmission duration pre-empted by a service with second transmission duration, by physical layer signaling, where the first transmission duration is larger than the second transmission duration. An apparatus for indicating a resource and a storage medium are further disclosed herein.

The present disclosure relates to methods for obtaining a quantity of blind detection times, and apparatus. One example method comprises receiving, by a terminal device, second information from a network device, where the second information comprises subcarrier spacing information, and determining, by the terminal device based on the subcarrier spacing information, a maximum quantity of blind detection times for the terminal device in a search space.

An apparatus and a method for allocating resources in a wireless communication system is provided. More specifically, a method of determining an uplink transmission resource region for performing a channel access procedure of the BS through a channel access procedure type and subcarrier spacing and determining configuration of downlink resources of the BS through scheduling information and slot structure information is proposed. A method of operating a terminal in a wireless communication system includes acquiring a maximum channel occupancy time (MCOT) of the terminal within an unlicensed band, determining a time interval which a base station (BS) can use for downlink signal transmission in the maximum channel occupancy time, transmitting the maximum channel occupancy time and time information related to the time interval to the BS and receiving a downlink signal from the BS during the time interval in the maximum channel occupancy time.

In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for generating, by a network entity for a user equipment (UE), a synchronization signal block (SSB) and an additional resource signal (RS) based on a variable function of a SSB subcarrier spacing (SCS) for communication after initial acquisition; and transmitting, by the network entity to the UE, the SSB including the additional RS.

Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.

According to one embodiment, a method for a terminal to detect a sidelink signal in a wireless communication system comprises: a step in which the terminal performs sweeping on a predetermined signal by using a predetermined window for correlation; and a step for determining that the predetermined signal is a sidelink signal on the basis of a peak detected at a portion corresponding to a predetermined cyclic prefix (CP) while performing the sweeping, wherein the size of the predetermined window corresponds to the longest symbol duration among the respective symbol durations of a plurality of subcarrier spacings.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate support of an extended cyclic prefix (ECP), where a duration of the ECP or transmitting the ECP is based on the indication. In some cases, the UE may receive an uplink grant to transmit an uplink message with an indication of the ECP, and the UE may transmit the ECP and uplink message according to a timeline based in part on the ECP. Additionally or alternatively, an uplink channel allocation indicated in the uplink grant may include a starting point for the ECP, where the UE transmits the ECP at the starting point. In some cases, the UE may multiplex uplink control information (UCI) in the uplink channel based on a timeline that is based in part on the ECP.

Embodiments of the present disclosure relate to methods, devices and computer readable media for communication on unlicensed band. In example embodiments, a method includes determining, at a terminal device, a time interval preceding a start symbol for uplink transmission. The method further includes determining, based on a first signal generating operation for the start symbol, a second signal generating operation for the time interval. The method further includes transmitting, to a network device over the time interval, a signal generated based on the second signal generating operation.
