Abstract: An apparatus (e.g., a user equipment or a base station) may be configured to mitigating clutter reflection in full-duplex mode operation. In some aspects, the wireless apparatus may perform transmit operations over a channel and determine a clutter context of the wireless apparatus. Further, the wireless apparatus may compare a sensed power level to a context threshold associated with the clutter context, the sensed power level indicating a power sensed on the channel by the wireless apparatus, and determine whether to operate on the channel in a full-duplex mode based on the comparing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information transmission comprising a resource allocation for downlink traffic and at least one dedicated table bit that indicates whether the UE is to use, to decode the downlink traffic, a first modulation order and a first target code rate corresponding to a first modulation and coding scheme (MCS) table or a second modulation order and a second target code rate corresponding to a second MCS table (a 1024 quadrature amplitude modulation table). The UE may decode the downlink traffic according to the first modulation order and the first target code rate or the second modulation order and the second target code rate based at least in part on at least one value of the at least one dedicated table bit. Numerous other aspects are described.

Abstract: Methods and apparatuses for wireless communication for line-of-sight Multiple-Input-Multiple-Output (LOS MIMO) are described. A first pilot signal is transmitted to a second device. The first pilot signal is at least one of a constant phase pilot or a linear phase ramped pilot for estimating a misalignment of a second antenna array of the second device with respect to a first antenna array of the first device.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify and schedule a set of bits in the physical uplink shared channel (PUSCH) for transmission of feedback for downlink transmissions occurring after transmission of the uplink grant scheduling the PUSCH. After receiving the uplink grant, a user equipment (UE) may receive control channel (PDCCH) transmissions that schedule downlink transmissions. The UE may monitor for and generate feedback for the downlink transmission. The UE may then utilize the bits indicated by the UL grant to transmit the feedback. In some examples, the UE may determine whether the indicated bits are adequate to transmit the feedback for the later downlink transmissions. When the UE determines that the extra bits are not adequate (e.g., there are not enough bits), then the UE may determine to transmit the feedback separate from the PUSCH resources scheduled by the uplink grant.

Abstract: A method of wireless communications by a receiving sidelink user equipment includes detecting a lite sidelink synchronization signal (SL-SS) transmitted by a transmitting sidelink UE. The lite SL-SS may have a pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols. The method also includes transmitting a demand requesting additional SL-SSs from the transmitting sidelink UE on indicated resources. Another method includes receiving a demand for additional sidelink synchronization signals (SL-SSs) from a receiving sidelink UE. This method further includes transmitting the additional SL-SSs in response to the demand.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration including a plurality of codebook subset restrictions. The UE may identify a codebook subset restriction, of the plurality of codebook subset restrictions, to be applied to precoding matrix indicator (PMI) selection associated with a slot. The UE may transmit a channel state information (CSI) report including an indication of a PMI selected based at least in part on the identified codebook subset restriction. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for allowing for the coexistence of legacy and non-legacy PUCCH formats. An example method generally includes generating a first orthogonal sequence for a first payload for a physical uplink control channel (PUCCH) to be transmitted; generating a second orthogonal sequence for a second payload for the PUCCH to be transmitted; mapping the first orthogonal sequence to a first set of virtual resources and the second orthogonal sequence to a second set of virtual resources; mapping the first set of virtual resources to a first set of physical resources and the second set of virtual resources to a second set of physical resources; and transmitting the first and second payloads for the PUCCH on the first and second sets of physical resources.

Abstract: A transmitting device applies a first MCS to a first set of data tones that overlaps with a first set of PRTs within a plurality of tones, the first set of PRTs being associated with a first PAPR reduction signal. The transmitting device applies a second MCS to a second set of data tones that overlaps with a second set of PRTs within the plurality of tones, the second set of PRTs being associated with a second PAPR reduction signal. The transmitting device can transmit a transmission signal comprising the first set of data tones and the second set of data tones, the transmission signal using a waveform based at least in part on the first PAPR reduction signal and the second PAPR reduction signal.

Abstract: Methods, systems, and devices for wireless communications are described. For example, an operator may utilize the duplexing gap as a second downlink channel for an operator that has an uplink channel next to the guard. an operator may utilize the duplexing gap as a second uplink channel for an operator that has a downlink channel next to the guard. In some examples, a new block may be added for an operator (e.g., the first operator, the second operator, or a third and distinct operator). The new block may include an uplink channel and a downlink channel (which are adjacent to respective uplink and downlink channels for other operators, hence avoiding additional interference). A new block may be added for an operator (e.g., the first operator, the second operator, or a third and distinct operator), which may be subdivided in time, frequency, or both.
