Abstract: Wireless communications systems and methods related to communicating uplink control information (UCI) in a network operating over multiple aggregated unlicensed carriers are provided. A first wireless communication device communicates, with a second wireless communication device, a downlink communication signal. The first wireless communication device communicates, with the second wireless communication device, an unscheduled uplink communication signal including an uplink report associated with the downlink communication signal, the unscheduled uplink communication signal communicated based on a listen-before-talk (LBT) procedure. The uplink report includes at least one of an acknowledgement (ACK) for data in the downlink communication signal, a negative-acknowledgement (NACK) for the data in the downlink communication signal, or channel information based at least on the downlink communication signal.

Abstract: Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.

Abstract: A wireless device may utilize enhanced OBSS identification techniques to determine whether an interfering transmission is associated with an OBSS. In an example, a wireless device may receive a WLAN packet that includes a preamble and a data region. The wireless device may analyze the preamble to determine whether the WLAN packet is an OBSS packet. If the wireless device determines there is insufficient information in the preamble to identify the WLAN packet as an OBSS packet, the wireless device may decode a portion of the data region (e.g., a MAC header) to determine if the WLAN packet is an OBSS packet. Prior to declaring a successful decoding of the MAC header, the wireless device may confirm the MAC header has been received reliably. Additionally or alternatively, BSS identifiers may be included in the data region and used to determine if the WLAN packet is associated with an OBSS.

Abstract: A user terminal for multiple-user wireless communication is provided, comprising a transmit buffer configured to store uplink data for transmission. The user terminal comprises a processor configured to generate a request to transmit frame in response to uplink data being present in the transmit buffer, and initiate a transmit timer for determining when to transmit the request to transmit frame. The user terminal comprises a transmitter configured to transmit the request to transmit frame when the transmit timer expires or when the uplink data present in the transmit buffer exceeds a threshold amount. The user terminal comprises a receiver configured to receive a clear to transmit frame from an access point based on the transmitted request to transmit frame. The transmitter is further configured to transmit the uplink data present in the transmit buffer, concurrently with at least one other user terminal transmitting uplink data, to the access point at a specified time based on receiving the clear to transmit frame addressed to the user terminal.

Abstract: A network configurator can dynamically configure a device to couple network data between other devices in a wireless network. The devices can include two independent wireless transceivers that can each operate within different frequency bands, such as the 2.4 GHz and 5.0 GHz frequency bands. The configuration of the independent wireless transceivers can be based, at least in part, on device capabilities of the wireless transceivers, channel conditions, and a quality of service associated with the other wireless stations in the wireless network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a physical downlink shared channel (PDSCH) transmission associated with a multi-PDSCH semi-persistent scheduling (SPS) that potentially conflicts with a second transmission in a slot. The UE may determine to keep at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission in the slot based at least in part on one or more rules. The UE may perform, with a base station in the slot, at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission that is kept based at least in part on the one or more rules. Numerous other aspects are described.
