摘要： A method is disclosed of a network node adapted to operate in association with first and second wireless communication devices associated with first and second latency requirements, respectively, wherein a latency of the second latency requirement is lower than a latency of the first latency requirement. The method comprises receiving a first scheduling request for uplink transmission by the first wireless communication device, and transmitting a first scheduling grant indicating an allocated first communication resource for the uplink transmission by the first wireless communication device. The method also comprises receiving (simultaneously with or after transmitting the first scheduling grant) a second scheduling request for uplink transmission by the second wireless communication device, determining whether the first communication resource and an allocated second communication resource for the uplink transmission by the second wireless communication device at least partly overlap, and transmitting a second scheduling grant indicating the second communication resource. The method further comprises (if it is determined that the first and second communication resources at least partly overlap) transmitting (to the first wireless communication device) a scheduling grant annulment instruction for preventing the uplink transmission by the first wireless communication device using the first communication resource. Corresponding method of the first network node is also disclosed, along with corresponding computer program product, arrangements, network node and first wireless communication device.

摘要： 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 p i (x). Each irreducible polynomial p i (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. Further, a corresponding computer program, a corresponding computer program product, and a checksum generator for generating a cryptographic checksum, are provided.

摘要： 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.

摘要： A base station initializes pseudo-random sequence generators on which wireless devices base generation of uplink reference signals. The base station determines a first sequence from a first subset of possible initialization sequences for a sequence generator of a first device, and determines a second sequence from a second subset of possible initialization sequences for a sequence generator of a second device. The range of this second subset spans at least the range of the first subset. The base station further encodes the first sequence as a first set of two or more parameters, and encodes the second sequence as a second set of one or more parameters. This second set includes at least one parameter not included in the first set, and comprises fewer bits than the first set. The base station initializes the sequence generators by transmitting the first and second sets of parameters to the devices.

摘要： Estimation of line insertion loss (IL (f) ) of a customer transmission line. For a number of different reference transmission lines the insertion loss is laboratory measured at a number of frequencies in double- ended line tests, giving insertion loss values (L11...L14,..., L51...L54). For the same reference transmission lines single-ended laboratory tests are performed, giving one calibration quantity (PV1...PV5) per transmission line, representing the amplitude of a far-end TDR reflection. A relationship is formed between the loss values (L11 L54) and the calibration quantity (PV1...PV5), shown as one straight line (Lf1...Lf4) per frequency (f1...f4). A field single-ended line test is performed on the unknown customer transmission line, giving a calibration quantity (PVX). The insertion loss (IL';(f) ) is read as values (LX1...LX4) for the different frequencies (f1…f4). The calibration quantity (PV1…PV5; PVX) can be measured via a line card or by connecting to the transmission line. For one transmission line different relationships can be set up depending on the termination impedance of the transmission line. Accurate customer transmission line insertion loss is generated.

摘要： A physical uplink control channel (PUCCH) format for transmission of uplink control information (UCI) in unlicensed spectrum is either short PUCCH or long PUCCH. The short PUCCH occupies less than 1 subframe in the time domain and spans an entire system bandwidth in the frequency domain with interlacing on a resource block level. The long PUCCH occupies one subframe in the time domain and spans the entire system bandwidth in the frequency domain with interlacing on a resource block level.
