  • Patent number: 11647497
    Abstract: Uplink radio transmissions (22) from a radio device (10) are scheduled by allocating radio resources for the uplink radio transmissions (22) and controlling a transmit power of the uplink radio transmissions (22). Depending on a bandwidth of radio resources to be allocated for an uplink radio transmission (22) and a current value of the transmit power, an estimate of the signal-to-noise ratio of the uplink radio transmission (22) is determined. The estimate of the signal-to-noise ratio is compared to at least one of the lower target and the upper target. Depending on a result of the comparison, the bandwidth is adapted, and radio resources for the uplink radio transmission (22) are allocated in accordance with the adapted bandwidth.

  • Patent number: 11570725
    Abstract: A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set.

  • Patent number: 11419071
    Abstract: Adopting a frequency multiplication scheme allows a network node to expand the number of transmit beams transmitted by it within a defined time interval, and allows the network node to transmit a greater number of synchronization signals on a per beam basis within the defined time interval. By way of example, the network node may operate in compliance with standardized restrictions regarding the timeframe during which it must transmit some base number of beam-based synchronization signals, while using a frequency multiplexing scheme to transmit additional beams within the same timeframe. Among the various advantages flowing from these operations, the ability to transmit more beams within the same timeframe allows the network node to tailor the beam shape and directions for broader coverage or enhanced range.

  • Patent number: 11102784
    Abstract: A method and network node for enabling mobility measurements performed by wireless devices. A set of resource blocks are distributed across an available frequency bandwidth, and a pre-defined maximum average transmit power per resource block is available for transmission by the network node. The network node transmits (5:3A) a subset of resource blocks using a first transmit power per resource block which is higher than the pre-defined maximum average transmit power per resource block. The network node also transmits (5:3B) other resource blocks in the set not included in the subset using a second transmit power per resource block which is lower than the pre-defined maximum average transmit power per resource block so that the total transmit power used for transmitting the set of resource blocks does not exceed a total available maximum transmit power.

  • Patent number: 11071077
    Abstract: A network sync signal with unknown frequency location is detected by sampling the received signal over a band of interest in frequency, and over the repetition period of the sync signal in time. The signal is converted to the frequency domain. Sub-bands of the frequency-domain signal, corresponding to different possible sync locations and frequency offsets, are extracted and converted to the time domain, where the sync signal is searched over the reception window length using time-domain matched filtering.

  • Patent number: 10856165
    Abstract: A communication device is arranged to operate in a cellular communication system and report Channel State Information, CSI, including a channel quality by a Channel Quality Indicator, CQI, which reports a CQI set. The communication device comprises a receiver arranged to receive antenna-specific reference signals, a channel estimator arranged to evaluate channel conditions from the reference signals to determine values of a CQI set, a reporting processor arranged to determine whether a bounded differential reporting format prevents values of the CQI set to be accurately reported, and to determine a CQI set such that the bounded differential reporting format allows the values of the CQI set to be reported to reduce under-reporting or over-reporting errors that arise from the use of the bounded differential reporting format, and to form a CSI report including the values of the CQI set using the bounded differential reporting format, and a transmitter arranged to send the CSI report.

  • Patent number: 10834676
    Abstract: A wireless device and a method therein for performing one or more operations based on available energy. The wireless device is configured to operate in a wireless communications network. Based on an amount of energy available for operation and based on control information, the wireless device determines an allocation of the amount of available energy between at least a first energy part and a second energy part. The first energy part is to be used in a sensing operation using a sensing operation configuration and the second energy part is to be used in a communicating operation using a communicating operation configuration. The wireless device performs based on the determined allocation, one or more operations out of: the sensing operation using the first energy part and the sensing operation configuration, and the communicating operation using the second energy part and the communicating operation configuration.

  • Publication number: 20200305170
    Abstract: A base station (11) of a wireless cellular communication network operating in unlicensed spectrum adjusts (118) the robustness of a downlink transmission in response to the power level of any interference encountered in the channel and the source of the interference. The base station (11) estimates (110) whether the source of interference encountered is a eLAA or WLAN network (110). An offset to a transmission format—a measure of transmission robustness to noise and interference—is calculated (112) in response to the interference power level and the source of the interference. An initial transmission format is adjusted (118) by the offset, and data are transmitted (120) to a UE using the adjusted transmission format. In other embodiments, the base station (11) may compare its interference to that detected by the target UE, to ascertain whether the two likely have the same source.

    Abstract: The present disclosure relates to methods and devices for Channel State Information, (CSI) prediction. More particularly the disclosure pertains to predicting CSI for a dynamic channel that is varying over time, e.g. because the receiver is moving. This object is obtained by a method performed in a first wireless node of predicting CSI of a dynamic wireless channel H between the first wireless node and a second wireless node. The method comprises deriving channel covariance estimates Ck(n), . . . , Ck(n?M) of the dynamic wireless channel H, estimating one or more channel properties of the dynamic wireless channel H, wherein one of the estimated channel properties defines a spectrum spread of the dynamic wireless channel H, and determining a covariance prediction filter, based on the estimated one or more channel properties.
