Abstract: Aspects described herein relate to communicating feedback in wireless communications. A user equipment (UE) can receive, in a downlink portion of a slot, data communications from a base station, where the data communications comprise multiple code blocks received in one or more downlink symbols. The UE can generate one or more feedback bits to provide feedback for the multiple code blocks. The UE can transmit, to the base station and in an uplink portion of the slot, an indication of the one or more feedback bits.

Abstract: A method and apparatus are provided for generating and reporting a reference power headroom report (PHR) for New Radio (NR). A user equipment (UE) decides to report a reference power headroom (PH) for at least one carrier frequency in a transmission time interval (TTI). The UE determines at least one of an index (j) of a target received power of a Physical Uplink Shared Channel (PUSCH) to be transmitted in the TTI and a path loss scaling factor, an index (qd) of a reference signal used for measuring path loss for the carrier frequency, or an index (l) of a power control process used for the carrier frequency. The UE then calculates the reference PH based on one or more of the determined at least one index, and reports, in the TTI, a PHR including the reference PH for the carrier frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an offset value from a first modulation and coding scheme relating to a first code rate for a payload data transmission. The UE may determine, for a transmission of uplink control information, a second modulation and coding scheme, relating to a second code rate, that is different from the first modulation and coding scheme based at least in part on the offset value. The UE may transmit the uplink control information using the second modulation and coding scheme based at least in part on determining the second modulation and coding scheme. In some aspects, a UE may segment uplink control information. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

Abstract: Methods, systems, and devices for wireless communication are described that support multiplexing uplink transmissions with transmit diversity with a single carrier waveform. Two or more UEs may be configured to use space time block codes (STBC) for transmissions using multiple uplink antennas. A first UE may be configured to use a first STBC for a first uplink transmission. An orthogonal cover code (OCC), such as a Walsh code, may be applied to the first STBC to generate a second STBC, and a second UE may use the second STBC for a second uplink transmission. The first UE and the second UE may concurrently transmit the first uplink transmission and the second uplink transmission. The first STBC and the second STBC may be applied across multiple OFDM symbols, or may be applied within an OFDM symbol on a modulated symbol level.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for utilizing a one-symbol space-time block code (STBC) process to encode control information for transmission on an uplink control channel. The one-symbol STBC process produces two code blocks, each for transmission on a different antenna. Each code block may be time domain spread across multiple single-carrier frequency division multiple access (SC-FDMA) uplink control channel symbols using the same spreading code to enable recovery of the code blocks at the receiver.

Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support flexible symbol configurations for uplink channels. In one example a method includes performing transmitting first uplink information from a subordinate entity to a scheduling entity in a long burst portion of one or more slots, and transmitting second uplink information from the subordinate entity to the scheduling entity in a combination of long burst and short burst portions of the one or more slots. Each of the one or more slots includes a portion that carries a physical downlink control channel. The second uplink information is transmitted in a physical uplink control channel

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Managing the coexistence of multiple different UE types and capabilities in wireless networks is disclosed. In order to handle the various transmission types and available UE capabilities, base stations may coordinate among each other over backhaul communications to schedule identifiable groups of UEs being served for specific sets of resources. The resources may be assigned, and UEs grouped, according to particular transmission types, UE capabilities, or a combination of both. Additional aspects may also provide for signaling to the UE that informs the UE of expected transmission types for given resources. The combined aspects facilitate reducing complexity of UE signal processing for data interference cancellation, signal decoding, and the like.
