    Abstract: Aspects of the present disclosure include methods and devices for wireless communication including an apparatus, e.g., a UE. The apparatus may be configured to receive one or more reference signals from each transmit beam of a set of transmit beams of a first base station through each receive beam of a set of receive beams of the UE. The apparatus may be further configured to determine a set of transmit-beam receive-beam pairs based on the received reference signals. The apparatus may be further configured to determine a subset of the transmit-beam receive-beam pairs of the set of transmit-beam receive-beam pairs that are mutually non-interfering with each other. The apparatus may be further configured to transmit, to a second base station, a report indicating information associated with the subset of the transmit-beam receive-beam pairs.

    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently reporting channel state feedback for a set of subbands. As an example, a user equipment (UE) may receive a set of reference signals on the set of subbands and determine a respective channel quality indicator (CQI) index for each of the set of subbands based on the reference signals. The UE may then transmit indications of CQI indices for different subbands of the set using variable length indications, such as indications that include different numbers of bits. Since, in some examples, a small length or number of bits may be allocated for reporting CQI indices with a high probability of being reported, overhead in a wireless communications system may be reduced.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station in a network of base stations may determine a predicted route of a user equipment (UE) based on sensor data obtained by sensors coupled with the base station. A neighboring base station may be located along the predicted route and the base station may provision the neighboring base station with a subset of beams associated with the neighboring base station. The subset of beams may include beams with geographic coverage areas overlapping with the predicted route of the UE. The base station may add the subset of beams to a provisioned route beam list and may transmit the provisioned route beam list to the neighboring base station in a message. The neighboring base station may use the subset of beams indicated in the provisioned route beam list for beamforming communications with the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to apply tone reservation to a downlink transmission from the base station to a user equipment (UE), and may select to rate match data of the downlink transmission around selected resource elements for the tone reservation instead of puncturing the data of the downlink transmission. The base station may transmit, to the UE, a message indicating that tone reservation is applied to the downlink transmission via rate matching, and transmit the downlink transmission including the data rate matched around the selected resource elements used for tone reservation. The UE may identify the selected resource elements used for tone reservation based on an estimation of a channel between the UE and the base station, and decode the data of the downlink transmission via rate matching around the selected resource elements used for tone reservation.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support short control messaging using index modulation on DMRS. In a first aspect, a method of wireless communication includes a base station determining a configuration action for a served user equipment (UE) in communication with the base station. The base station may then generate a short control message associated with the configuration action and map that short control message onto a set of inactive subcarrier resource elements (REs) of a demodulation reference signal (DMRS) sequence. The served UE may then receive the transmitted DMRS sequence and determine the short control message within the set of inactive subcarrier REs of the DMRS sequence. Other aspects and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described. An access device in a network of access devices may determine that a wireless device is in a coverage area of one of the access devices based on a coverage pattern of the access devices and a sensor coupled with the access device. The access device may estimate a trajectory of the wireless device based on information obtained by the sensor. After estimating the trajectory of the wireless device, the access device may transmit an indication to one or more of the other access devices to enter (or remain in) an active state based on the trajectory of the wireless device and the coverage pattern. The indication may also include a set of beams for the other access device to activate.

    Abstract: Methods, systems, and devices for wireless communications are described. In one example, a receiving device (e.g., a UE) may transmit, to a transmitting device (e.g., a base station), a capability indicator indicating a capability of the receiving device to perform peak reconstruction using soft metrics (e.g., expected value, covariance) on symbol decisions. The receiving device may receive, from the transmitting device and based on the capability indicator, control signaling indicating a clipping level applied to generate a signal and a subset of peaks clipped from the signal. The receiving device may receive the signal generated in accordance with the control signaling from the transmitting device and may decode a reconstructed signal based on performing the peak reconstruction on the signal using the soft metrics on symbol decisions, the clipping level, and the subset of the peaks clipped from the signal.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine, for a user equipment (UE) operating in a mobility state, route information. The BS may transmit, to the UE, information identifying a set of beams based at least in part on the route information. The UE may perform a set of neighbor cell measurements, in connection with movement along the predicted route, using the set of beams. Numerous other aspects are provided.
