  • Patent number: 11297520
    Abstract: Methods, systems, and devices are described for wireless communications. A first CSI reporting configuration may be used for communications using TTIs of a first duration and a second CSI reporting configuration may be used for communications using TTIs of a second duration. A determination of whether to report CSI based on the first and/or second configuration may be made, and a CSI report may be transmitted based on the determination. In some cases, CSI for the first CSI reporting configuration is determined differently than CSI for the second CSI reporting configuration. For instance, the CSI reporting configurations may use different reference resources and/or reference signal resources when calculating respective CSI. In some cases, the first and second CSI reporting configurations may be configured as a first CSI process and a second CSI process, which may be operated either independently or jointly.

  • Patent number: 11252738
    Abstract: The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.

  • Patent number: 11219024
    Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

  • Patent number: 11159977
    Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point.
