Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may generate a set of orthogonal sequences that the UE may use to convey a payload of a number of bits based on a product of an orthogonal matrix and a cell-specific sequence. The UE or the base station, or both, may select a subset of the set of orthogonal sequences based on the number of bits in the payload, and the UE may construct a codebook including the subset of orthogonal sequences. The UE may select an orthogonal sequence from the constructed codebook based on the bits in the payload. The UE may transmit the payload including the number of bits to the base station using the selected orthogonal sequence.

Abstract: A method and apparatus for improved transmission of ACK and NACK bits to a base station The example method may determine a distance between a first UE and a second UE based on one or more of a sequence length, a number of hypothesis, or a number of UEs sharing an OFDM symbol. The example method may determine a plurality of cyclic shifts for each of the first UE and the second UE. The example method may assign one or more sequences to each UE. The example method may receive, at the base station, a multiplexed signal, wherein the multiplexed signal includes at least one bit of uplink control information (UCI) from the first UE and the second UE multiplexed on an uplink short burst transmitted via the OFDM symbol. The method may enable the receipt of UCI from multiple UEs in a multiplexed signal.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control transmission and multiple downlink data transmissions to a user equipment (UE). The UE may schedule an uplink data transmission based on the downlink control transmission and may schedule transmission acknowledgement messages based on the multiple downlink data transmissions. The UE may identify that the scheduled uplink data transmission overlaps with the scheduled transmission acknowledgement messages. The UE may generate one or more acknowledgement codebooks for transmission of the multiple transmission acknowledgment messages and may multiplex the one or more acknowledgement codebooks with the uplink data transmission on the uplink data channel. In some cases, the UE may multiplex the codebooks based on determining that a set of timing thresholds are satisfied by an earliest of the multiple transmission acknowledgement messages and the uplink data transmission with respect to one or more downlink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink shared channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink shared channel transmission. Each frequency hop may be determined based on a corresponding uplink shared channel index for a respective repetition a frequency hop for each repetition of the uplink shared channel transmission. The uplink shared channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink shared channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a power headroom report for multiple radio access technologies (RATs). A user equipment (UE) may support multiple RATs that correspond to different transmission time intervals (TTIs). A UE may determine a reporting schedule for power headroom reports (PHRs) for a first RAT and a second schedule for PHRs for a second RAT. The UE may generate a PHR for the first RAT and a companion PHR for the second RAT, and may transmit the PHR and companion PHR based at least in part on the first PHR schedule. In some examples, the UE may receive a PHR type from the base station, and may determine a joint PHR based on the type. The UE may determine a joint PHR schedule based on a granularity of supported RATs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a high priority uplink control information (UCI) message, a low priority UCI message, and an uplink shared channel message overlap. The UE may select a first set of resources on the physical uplink shared channel for the high priority UCI message then select a second set of resources on the physical uplink shared channel for the low priority UCI message. The second set of resources may be non-overlapping with the first set of resources. The UE may transmit the high priority UCI message on the first set of resources, the low priority UCI message on the second set of resources, and the uplink shared channel message on a third set of resources on the physical uplink shared channel.

Abstract: Some aspects described herein relate to determining a length for a sequence for communicating a signal, determining a reduced length as a largest prime number that is smaller than a fraction of the length, generating a Zadoff-Chu sequence based on the reduced length, extending the Zadoff-Chu sequence to be of the length to generate the sequence of the length, and communicating the signal based on the generated sequence.
