  • Patent number: 11695509
    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.

  • Patent number: 11678364
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

  • Publication number: 20230174875
    Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

  • Publication number: 20230180177
    Abstract: A mobile device can report its capabilities to a network node regarding one or more phase characteristics between Sounding Resource Signal (SRS) resources transmitted by the mobile device under one or more circumstances, enabling the network to configure the mobile device accordingly. Such reporting can enable the network to coherently process multiple SRS resources, effectively increasing the bandwidth of the SRS resources and, ultimately, the accuracy of a position determination for the mobile device. Various techniques are provided for reporting capabilities and determining applicable conditions.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, based at least in part on two or more measurements on a channel taken at different points in time, that the channel is classified as static. The wireless communication device may perform at least one optimization based at least in part on determining that the channel is classified as static. For example, the at least one optimization may include modifying a channel state feedback procedure, reducing a periodicity associated with a measurement gap, modifying a filtering associated with measurements of the channel, reducing a threshold associated with beam switching, and/or refraining from performing at least one filtering at a radio frequency receiver of the wireless communication device.

  • Publication number: 20230133797
    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.

  • Publication number: 20230014069
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.
