摘要： Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

摘要： The base station may transmit to the UE, a first part and a second part of a PDSCH. The UE may decode the second part of the PDSCH. The first part of the PDSCH may be associated with a higher MCS than the second part of the PDSCH. The UE may estimate at least one of an ICI or a CPE associated with the PDSCH based on the decoding of the second part of the PDSCH. The UE may decode the first part of the PDSCH based on the decoding of the second part of the PDSCH. Decoding the first part of the PDSCH based on the decoding of the second part of the PDSCH may include correcting for the at least one of the ICI or the CPE associated with the PDSCH.

摘要： Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first serving cell for a set of transmission time intervals (TTIs) including a first TTI and receive a second slot format configuration for the first serving cell for the first TTI which is different from the first slot format configuration. The UE may determine, based on priorities of the slot format configurations, a first communication direction for the first serving cell for the first TTI. The UE may identify, for a second serving cell for the first TTI, a second communication direction indicated by one or more slot format configurations for the second serving cell. The UE may determine whether to communicate on the second serving cell for the first TTI according to the one or more slot format configurations for the second serving cell.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
