    Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

  • Patent number: 10396996
    Abstract: A method (500) of generating a cryptographic checksum for a message M(x) is provided. The method comprises pseudo-randomly selecting (502) at least two irreducible polynomials pi(x). Each irreducible polynomial pi(x) is selected based on a first cryptographic key from the set of irreducible polynomials of degree ni over a Galois Field. The method further comprises calculating (503) a generator polynomial p(x) of degree n=formula (I) as a product of the N irreducible polynomials formula (II), and calculating (505) the cryptographic checksum as a first function g of a division of a second function of M(x), ƒ(M(x)), modulo p(x), i.e., g(ƒ(M(x)) mod p(x)). By replacing a standard checksum, such as a Cyclic Redundancy Check (CRC), with a cryptographic checksum, an efficient message authentication is provided. The proposed cryptographic checksum may be used for providing integrity assurance on the message, i.e., for detecting random and intentional message changes, with a known level of security.

  • Patent number: 10356797
    Abstract: The present disclosure concerns radio communication. More particularly, the present disclosure concerns a possible reduction in overhead signaling. The radio link quality of a first radio link (e.g., DL) as well as a second radio link (e.g., UL) is obtained 130. Also, the obtained radio link quality of the first radio link is compared 140 with the obtained radio link quality of the second radio link. This is done in order to establish whether a similarity in the radio link quality is within a predefined tolerance. Next, the signaling for both the first radio link and the second radio link is controlled 150 if, or when, the similarity of the radio link quality is determined to be within said predefined tolerance.

  • Patent number: 10340991
    Abstract: Embodiments herein relate to a method performed by a network node for determining a precoder for a transmission to a first wireless device in a wireless communications network. The network node obtains at least a Rank Indicator, RI, of the channel used for transmissions to the first wireless device. The network node also obtains information about a preferred interference subspace for the transmissions to the first wireless device from a second wireless device in the wireless communications network, wherein the second wireless device is interfered by the transmissions to the first wireless device. The network node determines the precoder for the transmission to the first wireless device based on the obtained information about a preferred interference subspace if the at least obtained RI of the channel fulfills a first threshold criterion. Embodiments of the network node are also described.
