  • Patent number: 11974360
    Abstract: A method performed in a wireless device is disclosed. The present disclosure provides a method, performed in a wireless device, for polarization reporting. The wireless device is configured to communicate with a network node using a plurality of antenna panels of the wireless device, including a first antenna panel. The method comprises generating, based on one or more polarization properties of the first antenna panel, a first polarization indicator associated with a first identifier. The first identifier is indicative of the first antenna panel. The method comprises transmitting a capability report to the network node, the capability report comprising the first polarization indicator associated with the first identifier.

  • Patent number: 11924142
    Abstract: A method of operating a wireless communication device (101) includes receiving (3002) at least one downlink control message (411, 412, 4002) from a communications network (100), the at least one downlink control message (411, 412, 4002) being indicative of a frequency density (401-404) of uplink reference signals (31), the uplink reference signals (31) being for an estimation of a radio channel (114) between the wireless communication device (101) and the communications network (100) to coherently decode data signals encoding data of a uplink data transmission (4012), the uplink reference signals (31) and the data signals using the same precoding.

  • Patent number: 11923933
    Abstract: A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders. The method includes sending (405) an indication (304) relating to the selected precoder.

  • Patent number: 11914101
    Abstract: A method for partitioning a search direction when using least squares reverse time migration (LSRTM) is provided. LSRTM may be used iteratively in order to improve imaging accuracy. As part of LSRTM, multiple local line searches may be performed. In particular, image space may be partitioned, such as by using a set of masks. The search direction, such as the gradient, may be partitioned using the set of masks. Local line searches may be performed for each partition of the search direction, resulting in finding respective line search constants. The respective line search constants may then be used for iterating the model in order to improve imaging accuracy.

  • Patent number: 9766721
    Abstract: The present disclosure provides a method, a video system, and a system for realizing a simple air mouse. The method includes: a video terminal obtaining current position parameters of an air mouse, wherein the current position parameters comprise a deflection angle and a deflection direction of the air mouse with respect to an originally-calibrated coordinate position; and determining a position of a cursor on the video terminal according to the current position parameters and a preset scale parameter. By presetting reference points in the air mouse, the present disclosure obtains the deflection angle and the deflection direction of the air mouse with respect to the original position by the camera device based on the above reference points, and determines the position of the cursor on the video terminal according to the deflection angle and the deflection direction and the preset scale parameter.
