Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

Abstract: Apparatus, methods, and computer-readable media for wideband uplink control channel capability indication during initial access are disclosed herein. A user equipment (UE) may transmit an uplink message indicating an uplink resource bandwidth capability of a physical uplink control channel (PUCCH) of the UE based on a power spectral density (PSD) limitation and a maximum transmission power of the UE. The UE may receive a downlink message indicating an uplink resource allocation of the PUCCH corresponding to the uplink resource bandwidth capability. Alternatively, the UE may receive a downlink configuration that indicates a first set of uplink resources and a second set of uplink resources. The UE may transmit an acknowledgment message in response to a downlink message of a random access channel process. The acknowledgment message includes the uplink resource bandwidth capability that indicates a selection between the first set of uplink resources and the second set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving a first grant allocating a first set of downlink resources to the UE and a second grant allocating a second set of downlink resources to the UE, where the second grant is received after the first grant. The UE may determine that a slot comprises both resources of the first set and resources of the second set and generate a feedback codebook for downlink signaling scheduled to be received over one or both of the first set of downlink resources or the second set of downlink resources, where a size of the feedback codebook is based on the slot comprising both resources of the first set and resources of the second set. The UE may then transmit the feedback codebook to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for new radio (NR) communications in narrowband regions of unlicensed spectrum. A method that may be performed by a user equipment (UE) includes determining, using an energy detector (ED), that received energy in a first bandwidth (BW) is lower than a threshold; and transmitting, in response to determining that received energy in the first BW is lower than the threshold, a first uplink (UL) transmission to a base station (BS) in a second BW smaller than the first BW and contained within the first BW.

Abstract: A method of wireless communication includes determining, by a user equipment (UE) in response to a failed transmission to the UE by a base station, to transmit a negative acknowledgment (NACK). The method additionally includes transmitting, by the UE to the base station, the NACK in an acknowledgement (ACK) resource previously allocated by the base station, and triggering at least one action, by the UE in response to at least one of the determination to transmit the NACK or the transmission of the NACK. The at least one action improves retransmission success rate. In another aspect, a method of wireless communication includes receiving, by a base station from a UE, a NACK in an ACK resource previously allocated by the base station, and triggering at least one action, by the base station in response to the receipt of the NACK. The at least one action improves retransmission success rate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, via an autonomous uplink communication, one or more transport blocks to a base station. Each transport block may include a plurality of code block groups (CBGs). The base station may provide CBG-level feedback to the UE based at least in part on the autonomous uplink communication. In some examples, the base station may provide the CBG-level feedback in one or more downlink feedback information (DFI) packets. In some other examples, the base station may provide the CBG-level feedback via one or more uplink transmission grants. The UE may retransmit one or more CBGs from the autonomous uplink communication based at least in part on the DFI packets or uplink transmission grants.

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.
