Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a scheduling request to a base station. In some aspects, the user equipment may monitor for an ultra-reliable low latency communications type of response message from the base station based at least in part on transmitting the scheduling request to the base station, wherein the response message includes an indicator of an assignment of uplink resources for the user equipment or that the assignment of uplink resources is delayed, and wherein, based at least in part on the monitoring, the user equipment avoids retransmission of the scheduling request when the response message is detected or retransmits the scheduling request without delay when the response message is not detected. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks of a plurality of data blocks, each of the one or more data blocks received in one of a plurality of transmission occasions. The UE transmits an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE transmits a feedback history report for one or more transmission occasions of the plurality of transmission occasions.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to receive a plurality of combined signals. Each combined signal may be on a tone of a plurality of tones. The apparatus may be configured to determine a first pilot signal on a first tone of the plurality of tones. The apparatus may be configured to generate an interference-reduced signal for the first tone by canceling the determined first pilot signal from a first combined signal on the first tone.

Abstract: Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.

Abstract: Decoding and encoding methods, systems, and devices for wireless communication are described. One method may include receiving a codeword over a wireless channel, the codeword being encoded using a polar code, identifying a set of repeated bit locations in the received codeword, and identifying a set of bit locations of the polar code used for information bits for the encoding. The set of bit locations may be determined based at least in part on recursively partitioning bit-channels of the polar code for each stage of polarization and assigning portions of a number of the information bits to bit-channel partitions of each stage of polarization based on a mutual information transfer function of respective aggregate capacities of the bit-channel partitions. The method may also include decoding the received codeword according to the polar code to obtain an information bit vector at the set of bit locations, and other aspects and features.

Abstract: Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

Abstract: Various techniques provide for identifying and transmitting a first transmission to a UE in a first transmission time interval (TTI), and puncturing a portion of the first transmission with a higher priority second transmission that has a shorter TTI than the first TTI. The punctured portion of the first transmission may then be transmitted in a subsequent portion of the first TTI, concurrently with an originally allocated portion of the first transmission for that subsequent portion of the TTI. A UE may identify the punctured portion of the first transmission, and identify that the punctured portion of the first transmission is being transmitted in the subsequent portion of the first TTI. The UE may decode the received transmissions and merge the punctured portion with other, non-punctured, portions of the first transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may select a two sets of reference signal resource elements (REs) for a symbol period, where each RE of the first set is contiguous to an RE of the second set. The base station may also identify resource element groups (REGs) for control signaling, where each REG covers one or more resource blocks (RBs). The base station may then perform interference cancellation, which may be based on an interference covariance matrix for each of the REGs. In some cases, the base station may coordinate with neighboring base stations (directly or through the core network) to ensure that the selected REGs do not partially overlap with reference signal transmissions or REGs of neighboring base stations.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.
