  • Publication number: 20210226686
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a digital simulation to determine a precoding matrix indicator (PMI) associated with a digital reception beam. A base station may send, to the UE, a reference signal. The UE may perform a coarse beam search on the reference signal using non-oversampled digital reception beams. The UE may measure the signal strength of the reference signal for each of the non-oversampled digital reception beams and select the non-oversampled digital reception beam with the strongest signal. The UE may perform a refined beam search procedure on the selected beam by using a set of oversampled digital reception beams which correspond to the selected non-oversampled digital reception beam. The UE may determine the PMI associated with the strongest oversampled digital reception beam and send the PMI in a report to the base station.

  • Patent number: 11050465
    Abstract: Aspects are provided allowing a UE configured for Type II channel state feedback (CSF) to determine based on one or more antenna configurations or channel conditions whether to use the Type II codebook or to revert to a Type I codebook when computing CSF. Based on this determination, the UE may compute CSF based on the Type I codebook in situations where the performance gain of Type II codebooks may be reduced, thereby saving computational power, transmission power, and/or overhead when computing and reporting CSI feedback. The UE may subsequently transmit the CSF computed based on the Type I codebook in the allocated resources for Type II CSI feedback without the need for a separate signaling format, thereby simplifying and enabling reuse of the CSI feedback procedure.

  • Patent number: 11044668
    Abstract: Tracking reference signal designs for deployments without continuous reference signal transmission are described. The tracking reference signals may be extended in the frequency domain from a synchronization signal block and may occupy a subset or all of the symbol periods of the synchronization signal block. The tracking reference signals may have the same subcarrier spacing as synchronization signals and may be punctured in the frequency domain. Alternatively, the tracking reference signals may include common control reference signals transmitted periodically with paired reference signals in a data channel. The common control reference signals and paired reference signals may be transmitted regardless of the presence of control or data. For improved tracking after a transition to a connected mode or a long discontinuous reception (DRX) cycle, a slot including tracking reference signals may be repeated or an additional tracking reference signal pattern may be transmitted.

  • Patent number: 11032001
    Abstract: 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.

  • Patent number: 11019620
    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.

  • Patent number: 10993254
    Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.
