Abstract: Methods, systems, and devices for wireless communication using various patterns of data and reference signals are described. For example, in a system that supports operation using different duration transmission time intervals (TTIs), a base station may initiate communication with a user equipment (UE) or between two UEs, and UEs may communicate with the base station or with one another using an indicated pattern of data and reference signals. The base station may send a downlink control message indicating a transmission pattern selected from a set of patterns. UEs may identify the pattern based on the indicator and decode a sequence of data and reference signals based on the pattern. In some examples, the sequence may include a set of TTIs, which may have a shorter duration than other TTIs.

Abstract: A UE may determine a number of antenna ports associated with a frequency band that includes one or more CCs. The determined number of antenna ports may be based on a plurality of UL Tx chains for the one or more CCs/frequency band. The UE may switch from a first UL Tx chain to a second UL Tx chain, at least one of which may be associated with the one or more CCs/frequency band. The number of antenna ports may correspond to a maximum number of antenna ports of an individual CC of the one or more CCs, or to a sum of antenna ports of the one or more CCs. For the latter, the number of antenna ports may be limited to an available number of UE antenna ports when the sum of antenna ports is greater than the available number of UE antenna ports.

Abstract: Aspects are provided allowing a UE to transmit repetitions of an ULT, PEI-R, or other uplink reference signal for on-demand SSB, RMSI, or paging transmissions. A base station initially transmits an indication of a configured uplink repetition mode, which may comprise a first, second, or third mode in which a one-to-one, one-to-many, or many-to-many mapping exists between downlink reference signals and uplink occasions, respectively. Afterwards, the UE receives downlink reference signals via different transmission beams of the base station. In response to the downlink reference signals, the UE transmits an uplink reference signal repetition in one or more uplink occasions associated with one or more of the downlink reference signals according to the configured uplink repetition mode. In response to the uplink reference signal repetition, the base station may transmit a SSB, RMSI, or paging message. Thus, a balance between network energy savings and uplink signal reliability may be achieved.

Abstract: Methods, systems, and devices for wireless communication are described. A device may transmit first control signaling indicating a capability for switching between carriers of a group of carriers during uplink communications using carrier aggregation. The group of carriers include three or more carriers that are each associated with different radio frequency bands. The device may receive second control signaling that includes an indication for the device to switch to a subset of carriers of the group of carriers for transmission of an uplink message. The subset of carriers may be associated with a combination of radio frequency bands. The device may transmit the uplink message on at least one of the subset of carriers in accordance with a mapping between the combination of radio frequency bands and the at least one of the subset of carriers, where the mapping is based on the capability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station associated with a cell of a time division duplex communication system may determine a guard interval that is less than a maximum time delay, based at least in part on a radius of the cell, for air-to-ground communications; and transmit a scheduling configuration to a user equipment that identifies the guard interval. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a channel state information report in a subband full duplex slot using a first guard band. The UE may receive a physical downlink shared channel (PDSCH) communication. The UE may transmit an indication of an adjustment, based at least in part on the PDSCH communication, to use for a second guard band with respect to the first guard band. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion that spans at least multiple slots. The UE may select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for each of the multiple slots are determined independently from one another. The UE may interleave the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.
