Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may transmit, to a base station of a non-terrestrial network, a random access request message associated with a random access procedure using a transport block size (TBS) and a power control specified for the random access request message (e.g., a payload of the random access request message) for the random access procedure. The random access request message including a random access preamble and a random access payload carrying a buffer status report (BSR) or uplink data, or both. The UE may then monitor a response window based at least in part on transmitting the random access request message. The UE may receive, from the base station of the non-terrestrial network, a response message of the random access procedure during the response window.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a relationship between a first set of antenna ports, used for demodulation reference signals (DMRS) associated with a machine-type communication physical downlink control channel (MPDCCH) and used for the MPDCCH, and a second set of antenna ports used for cell-specific reference signals (CRS); receive CRS on one or more antenna ports of the second set of antenna ports; and receive the MPDCCH using at least the CRS based at least in part on the relationship. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a transmitting device may send transmissions using a first numerology for a first type of user equipment (UE). The transmitting device may partition a stream of modulated data symbol tones into one or more contiguous subsets of modulated data symbol tones that result in a roughly frequency-flat channel for a second type of UE. The transmitting device may then perform precoding on individual subsets of the one or more contiguous subsets of modulated data symbol tones, and may insert a frequency-domain cyclic prefix, cyclic postfix, or guard interval after each precoded subset. Thus, the first type of UE may communicate using the first numerology and the second type of UE may communicate using the first numerology but with the frequency-domain cyclic prefixes to address doppler spread experienced by the second type of UE.

Abstract: A base station may calculate a scheduling value based on at least one of a number of groups associated with a set of UEs operating on a cell provided by the base station a radio frame number, or a subframe number. The base station may send, based on the calculated scheduling value, at least one NRS in at least one PO on a narrowband control channel. A UE may receive, from the base station providing the cell, information associated with at least one PO for the UE. The UE may determine, based on the received information, scheduling information associated with at least one NRS in the at least one PO. The UE may detect the at least one NRS in the at least one PO on a narrowband control channel when the determined scheduling information indicates the at least one NRS is in the at least one PO.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.

Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.

Abstract: Methods, systems, and devices for wireless communications are described in which repetitions of communications may be configured for multi-transport block (TB) communications. A UE may determine that an acknowledgment of one or more initial repetitions of one or more TBs is received, and may cancel one or more subsequent repetitions of the acknowledged TB(s). The acknowledgment of the one or more initial repetitions may be provided by a base station in a new resource grant that provides an implicit acknowledgment of one or more TBs. In cases where multiple different TBs may be associated with the prior resource grant, the UE can determine to drop one or more repetitions after an implicit acknowledgment of a TB based on whether the resource grants are for a single TB or are for multiple TBs.
