Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may measure a RSRP of a CRS for each of a plurality of neighboring cells. The apparatus may also calculate an interference strength of each of the plurality of neighboring cells based on the RSRP measurement of the CRS for each of the plurality of neighboring cells. Additionally, the apparatus may compare a PDSCH demodulation performance of the UE based on rate matching for a CRS offset associated with each of the plurality of neighboring cells with the PDSCH demodulation performance of the UE based on skipping the rate matching for the CRS offset. The apparatus may also transmit a request for the rate matching or skipping the rate matching for the CRS offset based on the comparison of the PDSCH demodulation performance of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an actual power delay profile (PDP) associated with a channel between the UE and a base station, wherein the actual PDP indicates an averaged power level of the channel over a period of time. The UE may determine whether a channel estimation mode switching event is satisfied. The UE may switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a set of component carriers (CCs) associated with the UE. The UE may receive, from the base station, a message that activates or deactivates one or more CCs of the set of CCs. The UE may communicate, with the base station, after receiving the message, using one or more activated CCs of the set of CCs over a tuned radio frequency (RF) bandwidth that is based on receiving the message and based on the one or more activated CCs. Numerous other aspects are provided.

Abstract: An apparatus for wireless communication is provided. The apparatus may be a receiver device that includes an error correction decoder, such as a low-density parity check (LDPC) decoder. The apparatus may achieve power savings and/or operation cycle savings by disabling the error correction decoder in scenarios where bits of a codeword in a signal transmission are received without errors. The apparatus obtains a first set of bits of a codeword, wherein the codeword includes the first set of bits and a second set of bits, and wherein the second set of bits is punctured. The apparatus recovers the second set of bits based on at least the first set of bits and determines whether to operate an error correction decoder based on a result of an error detection operation performed on the codeword using the first set of bits and the second set of bits.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.

Abstract: A user equipment (UE) receives, from a base station, a message including at least one reporting configuration and resource configuration for a number of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT). Each of the configured CSI-IM resource patterns corresponds to a time and frequency location in a resource block of a neighbor cell associated with a second RAT. The UE transmits one or more CSI reports based on the reporting configuration(s) and the resource configuration(s).

Abstract: Aspects of the disclosure relate to a user equipment (UE) configured to schedule resource management procedures including measurements and tracking loop procedures. In some examples, the UE includes at least one antenna pair and two or more receivers. The UE may be configured to determine a plurality of combinations of antenna pairs and component carriers, where each component carrier is associated with a particular frequency. The UE may further be configured to schedule measurements/tracking loop procedures to available receivers first and utilize a selection algorithm to select combinations of antenna pairs and component carriers and map the selected combinations to the remaining of the available receivers to perform tracking loop procedures. Other aspects, features, and embodiments are also claimed and described.

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.
