  • Publication number: 20220376966
    Abstract: Provided are a method for a terminal transmitting uplink control information (UCI)through a physical uplink control channel (PUCCH) in a wireless communication system, and a terminal using the method. A transmission power to be applied to the uplink control channel is determined on the basis of a value subordinate to a PUCCH format, and at least one type of UCI is transmitted from the physical uplink control channel by using the transmission power that is determined, wherein when the PUCCH format is PUCCH format 3, and the at least one type of UCI includes acknowledgement/negative-acknowledgement(ACK/NACK) and periodic channel state information (CSI), the value subordinate to the PUCCH format is determined on the basis of the number of bits of the ACK/NACK and the number of bits of the periodic CSI.

  • Patent number: 11509656
    Abstract: In one embodiment, a method is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. The mobile communication device requests activation of a data session with a node via the wireless network and receives a reject message via the wireless network in response to the request for activation of the data session, the reject message including a cause code. If the cause code corresponds to a no-retry behavior of the data session retry mechanism of the mobile communication device, the mobile communications device no longer requesting activation of a data session with the node.

  • Publication number: 20220353549
    Abstract: Method and devices for coding point cloud data using an angular coding mode. The angular coding mode may be signaled using an angular mode flag to signal that a volume is to be coded using the angular coding mode. The angular coding mode is applicable to planar volumes that have all of their occupied child nodes on one side of a plane bisecting the volume. A planar position flag may signal which side of the volume is occupied. Entropy coding may be used to code the planar position flag. Context determination for coding may take into account angular information for child nodes or groups of child nodes of the volume relative to a location of a beam assembly that has sampled the point cloud. Characteristics of the beam assembly may be coded into the bitstream.

  • Patent number: 11477019
    Abstract: An elliptic curve random number generator avoids escrow keys by choosing a point Q on the elliptic curve as verifiably random. An arbitrary string is chosen and a hash of that string computed. The hash is then converted to a field element of the desired field, the field element regarded as the x-coordinate of a point Q on the elliptic curve and the x-coordinate is tested for validity on the desired elliptic curve. If valid, the x-coordinate is decompressed to the point Q, wherein the choice of which is the two points is also derived from the hash value. Intentional use of escrow keys can provide for back up functionality. The relationship between P and Q is used as an escrow key and stored by for a security domain. The administrator logs the output of the generator to reconstruct the random number with the escrow key.

  • Patent number: 11477735
    Abstract: Described herein are systems and methods to increase battery life of a user equipment (UE) by reducing the amount of time a UE spends in active time listening for paging messages following mobile originate (MO) or mobile terminated (MT) data transfers. A network node may receive, from a UE, a message including an identifier of the UE and a request to set the duration of an active time timer to zero. The network node may determine whether any MT traffic is available for the UE, and send a message to the UE including the duration of the active time timer or some other indicator to indicate to the UE whether or not MT data is awaiting transmission.
