Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to transmissions during an idle period of a fixed frame period (FFP). For example, a UE can receive, via system information or radio resource control (RRC) signaling, a FFP defining an idle period. The UE can further determine that a physical random access channel (PRACH) occasion (RO) resource or a physical uplink shared channel (PUSCH) occasion (PO) resource overlaps with the idle period of the FFP. The UE can additionally map the RO resource to the PO resource based on determining that the RO resource or the PO resource overlaps with the idle period of the FFP, and perform a random access channel (RACH) procedure according at least to the mapping of the RO to the PO.

Abstract: Wireless communication systems and methods related to multiplexing of uplink control information (UCI) and configured grant-UCI (CG-UCI) of different priorities are provided. A user equipment (UE) determines that a first resource for an uplink transmission associated with a first priority at least partially overlaps with a second resource for a first configured grant-physical uplink shared channel (CG-PUSCH) transmission associated with a second priority different from the first priority. The UE determines whether the first priority is higher than the second priority. In response to determining whether the first priority is higher than the second priority, the UE transmits one of the uplink transmission in the first resource or the first CG-PUSCH transmission in the second resource and refrains from transmitting the other one of the uplink transmission in the first resource or the first CG-PUSCH transmission in the second resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating one or more fixed frame period (FFP) configurations in a frame based equipment (FBE) mode. The UE may receive, from the base station, downlink control information (DCI) that schedules an uplink transmission, wherein the DCI includes content to enable or disable a UE-initiated channel occupancy time using the one or more FFP configurations. The UE may determine whether to initiate a channel occupancy time or share a channel occupancy time initiated by the base station to perform the uplink transmission based at least in part on the content in the DCI scheduling the uplink transmission. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include identifying, for the UE, a configuration of a set of resource block sets of a radio frequency spectrum band, receiving, from a base station, a downlink control information message indicating, for each resource block set of the set of resource block sets, a communication direction for the resource block set, and communicating with the base station using one or more resource block sets of the set of resource block sets according to one or more communication directions indicated by the received downlink control information message, the one or more communication directions corresponding to respective ones of the one or more resource block sets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer after transmitting an uplink communication on a physical uplink shared channel to a base station using a configured grant. The UE may determine whether the uplink communication is acknowledged as received by the base station based at least in part on determining whether a downlink communication from the base station is detected within a time duration associated with the timer. Numerous other aspects are provided.

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 first base station may sense a channel based at least in part on a sensing time period. The first base station may receive, from a user equipment (UE), a dynamic frequency selection (DFS) signal on the channel during the sensing time period. The first base station may determine to refrain from communicating on one or more of a beam associated with the DFS-assisted signal or the channel on which the DFS-assisted signal is received for a defined duration of time, based at least in part on an indication of the one or more of the beam or the channel being added to a non-occupancy list. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may receive one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device. The transmitting device may encode, at the L2 layer, the one or more SDUs according to one or more network coding parameters to obtain at least one encoded protocol data unit (PDU), the one or more network coding parameters comprising a rateless code. The transmitting device may generate, for the at least one encoded PDU, at least one corresponding PDU header. The transmitting device may output the at least one encoded PDU and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices.

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: Abstract: Methods, systems, and devices for wireless communications are described. In some sidelink communications systems, an anchor user equipment (UE) may allocate a set of subchannels to a client UE for a forward link transmission from the anchor UE to the client UE. The anchor UE may use a control region of one or more subchannels of the set of subchannels allocated to the client UE for one or more control-only transmissions. The anchor UE may transmit a rate-matching indication field to the client UE to indicate a rate-matching status of the set of subchannels that are allocated to the client UE, which may indicate on which subchannels the client UE may rate-match around a control region of the subchannel to receive the forward link transmission.
