Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message associated with scheduling uplink transmissions from the UE on a set of component carriers (CCs). The DCI message may indicate that a first uplink channel on a first CC of the set of CCs at least partially overlaps in time with a second uplink channel on a second CC of the set of CCs. The UE may multiplex, based on the first uplink channel at least partially overlapping in time with the second uplink channel, uplink control information (UCI) with an uplink data transmission on the first CC or the second CC. The UE may transmit the UCI and the uplink data transmission multiplexed on the first CC or the second CC based at least in part on the DCI message.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

Abstract: Determining, by a user equipment (UE) of a wireless communication system, that a physical uplink control channel (PUCCH) transmission of the UE carrying uplink control information (UCI) will collide upon transmission with another physical uplink shared channel (PUSCH) transmission of the UE. The UE then multiplexes, in response to the determining, the UCI on the PUSCH transmission based on one or more of the beam of the PUCCH transmission and the beam of the particular PUSCH transmission.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a UE. An example method by a user UE generally includes identifying overlapping uplink transmissions, performing a cancelation procedure involving at least one of the overlapping uplink transmissions based on one or more factors, before or after performing at least one of a first step of a multiplexing procedure to resolve overlapping uplink transmissions with a same priority or a second step of the multiplexing procedure to resolve overlapping uplink transmissions with different priorities, and transmitting at least one of the overlapping uplink transmissions after performing the cancelation procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal that is transmitted by a base station with a modulation signature associated with a reconfigurable intelligent surface (RIS) or a repeater and redirected by the RIS or the repeater using modulation that reverses the modulation signature associated with the RIS or the repeater. The UE may decode the signal, wherein the signal is decodable by the UE based at least in part on the signal being redirected by the RIS or the repeater using the modulation that reverses the modulation signature associated with the RIS or the repeater. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first configuration information indicating a first guard interval associated with sidelink communications. The UE may transmit, to a base station and another UE, a first sidelink communication using the first guard interval. The UE may transmit, to the base station and using a second guard interval having a second length that is different from a first length of the first guard interval, an uplink communication. Numerous other aspects are described.

Abstract: Method and apparatus to link a Msg4 PUCCH coverage enhancement and a Msg3 repetition request. The apparatus transmits a PRACH to initiate a RACH procedure, the PRACH including a request for a first coverage enhancement associated with the RACH procedure. The request includes information related to at least a second coverage enhancement associated with an acknowledgement associated with the RACH procedure. The apparatus receives a random access response associated with the RACH procedure. The first coverage enhancement may correspond to a repetition request for a RRC connection request message. The second coverage enhancement may correspond to a repetition request for an RRC connection setup message.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel state information (CSI) reporting. One aspect provides a method for wireless communication by a first user equipment (UE). The method generally includes transmitting, to a second UE, an indication of a capability of the first UE for reporting sidelink channel state information (SL-CSI) to the second UE, receiving, from the second UE, a request for SL-CSI, and reporting SL-CSI to the second UE subject to the capability of the first UE for reporting SL-CSI to the second UE.
