    Abstract: Methods, systems, and devices for wireless communications are described that provide for an originating network entity to request sub-band interference cancellation (SBIC) information from one or more neighboring network entities for downlink communications via one or more sub-bands. The neighboring network entities may serve at least one user equipment (UE) using adjacent sub-bands to the one or more sub-bands of the originating network entity. The originating network entity may exchange information related to sub-bands of interest to the one or more neighboring network entities, and whether SBIC is to be activated or is not to be activated for only the identified sub-bands versus across all operating sub-bands. The one or more neighboring network entities may configure measurement reporting by the UE for multiple time periods, corresponding to when transmissions are present and absent from the allocated sub-band(s) of the originating network entity.

    Abstract: A first network node may transmit, to a second network node via a PHY SERS, and the second network node may receive, from the first network node via the PHY SERS, an indication of a first subset of a set of parameters associated with a PHY signature. The first network node may transmit, to the second network node via L3 signaling, and the second network node may receive, from the first network node via L3 signaling, an indication of a remaining subset of the set of parameters associated with the PHY signature. The first network node may transmit, to the second network node, and the second network node may receive, from the first network node, a message based on the PHY signature. The second network node may decode the message based on the PHY signature.

    Abstract: Various aspects of the disclosure relate to a closed loop control of user equipment (UE) or base station (BS) power amplifier nonlinearity. One aspect provides a method of reporting an out-of-band power measurement by a UE in a wireless communication network. A UE may receive a downlink data traffic signal on a physical downlink channel from a base station. The UE may then measure an out of band (OOB) power of the received downlink data traffic signal, the receive OOB power comprising an average power of the downlink data traffic signal in one or more (OOB) locations of the wireless communication network offset from the physical downlink channel. The UE may then generate an OOB power measurement information element (IE) indicating the measured OOB power and send the OOB power measurement IE to the base station in an uplink control channel.

    Abstract: Certain aspects of the present disclosure provide techniques for training a digital pre-distorter (DPD) using real-time over-the-air transmissions and receptions by a user equipment (UE). A method for training the DPD generally includes transmitting a signal, generated by a transmitter front end, via a first port; sampling the signal, received over the air, at a second port; performing signal processing cleaning (e.g., synchronization, linear over-the-air channel estimation and equalization); calculating coefficients for a DPD; and configuring the DPD with the coefficients, for use in digitally pre-distorting sub sequent transmissions.

    Abstract: Aspects are provided which allow a UE to apply a modified interference cleaning data to account for differences in interference between at least one pilot resource and at least one data resource, thereby improving data decoding performance of the UE. The UE receives at least one pilot resource and at least one data resources from a base station and identifies interference cleaning data based on the pilot resource. The UE then determines whether a first interference affecting the pilot resource is the same as a second interference affecting the data resource. When the first interference is the same as the second interference, the UE applies the interference cleaning data to the data resource. Otherwise, when the first interference is different than the second interference, the apparatus applies a modified interference cleaning data to the data resource.

    Abstract: Aspects of the disclosure relate to dynamically adapting the mapping between spectral efficiencies and channel quality indicators in real-time based on the channel conditions. In some examples, a scheduled entity (e.g., a UE) may maintain two or more predefined tables or other mappings, each including a respective mapping between spectral efficiency threshold values and channel quality indicators for a respective channel type. The UE may then calculate respective weighted sums of the spectral efficiency threshold values across the two or more predefined tables based on the current wireless channel. For example, the UE may estimate the wireless channel and determine respective weights to be applied to the spectral efficiency threshold values across the two or more predefined tables based on the channel estimate. Other aspects, features, and embodiments are also claimed and described.

    Abstract: Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The base station may mitigate the link adaptation convergence transient upon performing a beam switch by modifying the modulation and coding scheme (MCS) according to a difference in reference signal received power (RSRP) between the old beam and the new beam. The base station may further adjust the MCS utilizing an outer-loop link adaptation process or channel state feedback (CSF) provided by the UE after the beam switch. Other aspects, features, and embodiments are also claimed and described.

    Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.
