Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Methods, systems, and devices for wireless communication are described. In a new radio (NR) system, a wireless device may encode control information into a codeword using a polar code. The device may prioritize certain information within the codeword due to the time criticalness of that information for processing at a receiving device. For example, information related to frequency allocation may be encoded such that the receiving device may decode the frequency allocation information early in the decoding process. The device may include partial parity checks throughout the codeword, so that the receiving device may test whether the decoded bits for the prioritized information pass a parity check, and may then send these decoded bits for processing before completing decoding of the codeword. In some cases, the device may encode the information to be transmitted using multiple evenized codewords, or using a single consolidated codeword.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a scheduling entity. The scheduling entity transmits control information in a control portion of the subframe, the control information corresponding to data information within the subframe, transmits the data information in a data portion of the subframe, receives a pilot signal from the set of subordinate entities in a pilot portion of the subframe, and receives an ACK/NACK signal from the set of subordinate entities in an ACK portion of the subframe. The ACK portion is subsequent to the pilot portion of the subframe. The ACK/NACK signal includes acknowledgment information corresponding to the data information. The control portion, the data portion, the pilot portion, and the ACK portion are contained in the same subframe.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying a transmission timing of a control reference signal transmitted over a radio frequency spectrum band during an OFF duration of the UE with respect to the radio frequency spectrum band, in which the identified transmission timing is relative to a transition from the OFF duration to an ON duration of the UE with respect to the radio frequency spectrum band; receiving the control reference signal at the identified transmission timing; and performing a warm-up procedure, before the ON duration, based at least in part on the identified transmission timing of the control reference signal. A method for wireless communication at a wireless network includes indicating, to the UE, the transmission timing of the control reference signal; and transmitting the control reference signal at the indicated transmission timing. The OFF duration and the ON duration are coordinated with a wireless network.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may be configured to transition to communicating on a first bandwidth part from communicating on a second bandwidth part. In order to ensure that the UE is able to perform receiver processing for demodulating data received on the first bandwidth part, after transitioning to communicating on the first bandwidth part, the UE may be configured to perform receiver processing using reference signals received on the second bandwidth part. That is, for a configured period of time, before the UE is able to perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the first bandwidth part, the UE may perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the second bandwidth part.

Abstract: Aspects of the disclosure provide a slot structure (e.g., the arrangement of channels and pilot signals within a slot) that can relax the processing timeline for a wireless communication device. For example, in the first or initial symbol of a slot, control information may be frequency division multiplexed (FDM) with a demodulation reference signal (DMRS) or with user data. In some cases, delayed-processing data may be sampled, and the samples may be buffered at the receiving device, for processing later, after control information needed to process the data has been received and processed. Further aspects provide for payload pre-tapering. That is, when a device delays the processing of data bits, this can cause a processing bottleneck after that buffering delay. By virtue of various pre-tapering techniques described herein, the processing load needed to process the delayed-processing data can be reduced. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message from a base station. The downlink control message may include a grant for communication with the base station and an indication of a component carrier (CC) to use for transmission of uplink control information (UCI). The UE may determine a CC for UCI transmission based at least in part on the CC indication, and the UE may transmit an uplink message including the UCI via the determined CC.

Abstract: Techniques are described herein for scheduling communication resources of a bandwidth part (BWP) after a BWP switching event when the frequency range of an active BWP is different than the frequency range of a target BWP. A user equipment (UE) may interpret the resource allocation field in scheduling downlink control information (DCI) that triggers a BWP switching event based on the active BWP. The UE and a base station may be configured to communicate using at least a portion of the resources of the active BWP in the first transmission opportunity after the BWP switching event. In subsequent transmitting opportunities where a scheduling DCI for the target BWP is received by the UE, the UE may interpret the resource allocation field of the new DCI as being based on the target BWP.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for grant processing in uplink centric subframes. An example method generally includes transmitting a first subframe comprising a first grant that includes information for one or more transmissions on that allocated resources in the first subframe to a user equipment (UE) and transmitting the first subframe, with a second grant that allocates resources in at least a second subframe to occur after the first subframe. Other aspects, embodiments, and features are also claimed and described.
