Abstract: A method of wireless communication, by a user equipment (UE), includes selecting a resource from a dedicated physical sidelink control channel (PSCCH) resource pool that has multiple potential PSCCH time domain resources with a mini-slot structure. The method also includes transmitting a mini-slot first stage sidelink control information (SCI-1) message on the selected resource. The mini-slot SCI-1 message is decoupled from a physical sidelink shared channel (PSSCH) associated with a data resource pool.

Abstract: A configuration for transmission control for multi-relay based communication. The apparatus determines a priority of data transmission at each relay of a plurality of relays between the base station and at least one UE. The apparatus transmits a PDSCH comprising control information for the at least one UE and a priority indication instructing each relay of the plurality of relays which data is contained in the PDSCH. The PDSCH may include an indication indicating whether data corresponding to the at least one UE is contained in the PDSCH. The PDSCH may include a field that identifies data and a corresponding UE of the at least one UE that is contained in the PDSCH. The apparatus may transmit, to each relay of the plurality of relays, the priority of data transmission, wherein the priority of data transmission includes a priority for uplink and downlink transmissions.

Abstract: Wireless communications systems and methods related to routing communications in a multiple-relay environment are provided. A base station (BS) transmits, to one or more wireless communication devices, a reference signal configuration indicating one or more reference signal resources. The base station receives, from a first wireless communication device of the one or more wireless communication devices, a channel state report based on one or more reference signals in the one or more reference signal resources. The channel state report includes channel measurement information for one or more links, each link connecting a wireless communication device of the one or more wireless communication devices to a user equipment (UE). The BS transmits, to the UE via a second wireless communication device of the one or more wireless communication devices based on the channel state report, a data signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant scheduling an uplink transmission that is not aligned with a fixed frame period (FFP) boundary configured for the UE. The UE may receive downlink control information (DCI) including an indication that the UE is to initiate a channel occupancy time (COT) acquisition in association with transmitting the uplink transmission. The UE may modify the indication based at least in part on the uplink transmission not being aligned with the FFP boundary and the indication indicating that the UE is to initiate the COT acquisition. The UE may transmit the uplink transmission based at least in part on the uplink grant and after the modification of the indication. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for a wireless communication device to configure and indicate sidelink control information (SCI) for sidelink communication within a slot over a sidelink channel. The SCI can include first stage SCI (SCI-1), second stage SCI (SCI-2), and third stage SCI (SCI-3). The SCI-1 may be transmitted within a control region of the slot, whereas the SCI-2 and the SCI-3 may be transmitted within a data region of the slot. The SCI-2 may include information for decoding SCI-3, including, for example, a resource size, modulation order, and rate-matching behavior of the SCI-3. The sidelink communication can further include sidelink data traffic that may be communicated in the data region of the slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an uplink request including an indication that data associated with the uplink request is delay sensitive. The UE may receive, from the base station, an uplink grant associated with a logical channel group including a logical channel for the data, wherein the logical channel group is associated with a higher priority than one or more other logical channel groups. The UE may transmit, to the base station and using the logical channel, the data, based at least in part on the uplink grant. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to cross Component Carrier (CC) transmission are provided that assist in minimizing PAPR. A first wireless communications device repeats data across multiple CCs in order to increase coverage while maintaining power levels within approved limits. In order to reduce PAPR, a number of different methods and mechanisms may be used. Rate matching may be performed across the multiple CCs as though a single virtual BWP. Alternatively, each copy of the data on its separate CC may be modified differently in some way, such as by using different scrambling IDs or different redundancy versions. Additionally, when utilizing DFT-s-OFDM modulation, an alternative method is provided which may lower PAPR. The DFT method includes performing a DFT on the combined data, tone mapping to each of the carriers, and performing an IFFT for each carrier individually. Each IFFT may be different than the other.

Abstract: The apparatus of wireless communication includes a UE and a base station. The base station may transmit, to the UE, a configuration for a plurality of PDCCH monitoring groups for monitoring different sets of search spaces. The plurality of PDCCH monitoring groups may include a first PDCCH monitoring group with a first number of PDCCH monitoring occasions and a second PDCCH monitoring group with a second number of PDCCH monitoring occasions different from the first number. The base station may determine which PDCCH monitoring group to send a PHCCH, and transmit the PDCCH to the UE. The UE may determine to monitor search spaces of the PDCCH monitoring group, and monitor search spaces corresponding to the PDCCH monitoring group. The UE may switch between the first and second PDCCH monitoring groups based on a condition or an indication from the base station.
