Abstract: A synchronization signal block (SSB) transmitted by a neighbor base station may interfere with a physical downlink shared channel (PDSCH) transmitted by a serving base station. A user equipment (UE) that receives both the SSB and PDSCH may mitigate the interference to improve an error rate of decoding the PDSCH. The UE may receive a first SSB including a first broadcast channel (BCH) from a second base station other than a serving base station. The UE may decode the first SSB. The UE may determine, based on the first SSB and the first BCH, that the PDSCH scheduled by the serving base station will overlap with a second SSB from the second base station. The UE may estimate a channel of the second SSB based on the decoded first SSB. The UE may remove a reconstructed second SSB from the PDSCH. The UE may decode the PDSCH.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) determining a wideband channel quality indicator (CQI) in a wireless communication network. For each of a plurality of CQI hypotheses, a UE divides a bandwidth into a plurality of frequency segments and determines an average spectral efficiency (SPEF) for each of those segments. Further, for each of the plurality of CQI hypotheses, the UE determines the minimum of the average SPEFs. The UE selects the CQI hypothesis corresponding to the maximum from among these determined minimum average SPEFs, and transmits this selected CQI as a wideband CQI. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first communication having a first frequency offset correction applied. The UE may receive an indication of a frequency offset of the first communication. The UE may transmit a second communication having a second frequency offset correction applied, the second frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first communication. Numerous other aspects are described.

Abstract: Techniques are provided for reporting, by a device, positioning-related information to a network entity. In an example, the device receives signaling information of the network entity. The signaling information indicates one or more parameters for a report on a reference signal that is transmitted by a base station. The device also receives multiple propagations of the reference signal upon a transmission of the reference signal by the base station. Based on the signaling information, the device generates the report, where the report comprises a power and a time delay per propagation of the reference signal. The device transmits the report to the network entity, where a position of the device is determined by the network entity based on the report.

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: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode

Abstract: A user equipment (UE) may reduce a peak to average power ratio (PAPR) ratio for an uplink transmission. The UE may receive an indication of an allowed error vector magnitude (EVM) for each of an uplink data signal, an uplink reference signal, and an uplink control signal from a base station. The base station may determine the allowed EVM based on a signal to noise ratio (SNR) for the UE measured at the base station. The UE may generate one or more uplink signals. The UE may apply a PAPR reduction to the one or more uplink signals based on the allowed EVM corresponding to each of the one or more uplink signals. The UE may transmit the one or more uplink signals to the base station.

Abstract: A transmitting device may reduce a peak to average power ratio (PAPR) ratio by clipping samples that have an amplitude exceeding a threshold. For a downlink transmission, the transmitting device may transmit an incremental peak suppression information message (PSIM) to multiple user equipments (UEs). A UE may receive downlink control information (DCI) indicating a data and a modulation and coding scheme (MCS) for the UE, and at least a first incremental PSIM. The UE may decode at least the first incremental PSIM that is applicable to a MCS lower than or equal to the MCS for the UE. The UE may determine whether to decode one or more subsequent incremental PSIMs based on the MCS for the UE. The UE may apply peak information from the incremental PSIMs to the data channel. The UE may decode the data channel based on the MCS for the UE.

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.
