  • Patent number: 12081301
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may support communication of a compressed channel state information (CSI) feedback. The UE and the network entity may use closed-loop feedback to improve beamforming tracking accuracy. For example, the UE may receive a CSI reference signal (CSI-RS) that is beamformed based on a channel estimate of a sounding reference signal (SRS) or a previous CSI feedback, or both. The UE may transmit a feedback message including compressed CSI that is generated through encoding a measurement of the CSI-RS. The compressed CSI may be generated based on a predicted channel estimate at the network entity, determined based on the channel estimate of the SRS or the previous CSI feedback.

  • Patent number: 12068901
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.

  • Patent number: 12047310
    Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

  • Patent number: 12047993
    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.

  • Publication number: 20240183935
    Abstract: Aspects presented herein may enable a wireless device (e.g., a joint FMCW radar and communication system) to transmit and/or receive an FMCW signal and an OFDM signal using the same time and frequency resources. In one aspect, a first wireless device receives an indication of a scheduled transmission for an FMCW waveform via a set of time-frequency resources. The first wireless device transmits or receives the FMCW waveform via the set of time-frequency resources based on the indication, where the FMCW waveform is separated from an OFDM waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the FMCW waveform and the OFDM waveform.

  • Patent number: 12004129
    Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

  • Patent number: 11991740
    Abstract: Methods, systems, and devices for wireless communications are described in which multiple operators may perform spectrum sharing using shared radio units (RUs), where the multiple different operators can access a same RU for communications with a user equipment (UE). A shared RU may receive requests for resources from two or more network nodes of two or more different network operators, for wireless resources in a first time period. The RU may determine a first resource allocation for the first time period based on different priorities of the different network operators. A first network operator may have a higher priority than a second or third network operator, and resources may be allocated to the first network operator ahead of the second or third network operators. The RU may transmit the first resource allocation to each of the different network nodes that transmitted requests for resources.

  • Patent number: 11916826
    Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

  • Patent number: 11910325
    Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.

In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

  • Publication number: 20240040555
    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.
