  • Publication number: 20220248300
    Abstract: A method, network node and processor for processing uplink signals transmitted from a wireless device (WD) to provide a combination of quantize-forwarding and decode-forwarding relayed signals in massive multiple input multiple output (MIMO) heterogeneous networks (HetNets). According to one aspect, whether quantize-forwarding or decode-forwarding is used depends on a ratio of a quality of a WD signal received at a Small Cell Base Station (SCBS) to a quality of the WD signal received at a Macro Cell Base Station (MCBS). When the ratio is less than a first threshold, signals received at the SCBS may be quantize-forwarded to the MCBS and when the ratio exceeds a second threshold larger than the first threshold, signals received at the SCBS may be decode-forwarded to the MCBS. When the ratio lies between the first and second threshold, signals received at the SCBS may be quantize-forwarded to the MCB.

  • Publication number: 20220132509
    Abstract: Regarding a first radio frequency (RF) carrier, a network node of a wireless communication network configures two or more bandwidth parts (BWPs) in the first RF carrier, each BWP aligning with a respective one of two or more other RF carriers positioned within the RF spectrum spanned by the first RF carrier. The node determines a frequency-sharing configuration for each BWP, in dependence on radio resource usage of the respective other RF carrier and configures wireless communication devices to use respective ones of the BWPs. For example, the node determines a resource-usage pattern for control-related signaling conveyed on the other RF carriers and transmits rate-matching information for the BWPs of the first RF carrier. Each BWP occupies RF spectrum used by a respective one of the other RF carriers, and the rate-matching information transmitted for each BWP depends on the resource-usage pattern determined for the respective other RF carrier.

  • Publication number: 20220103321
    Abstract: Embodiments of methods in a base station and a UE are disclosed. In some embodiments, a method implemented in a network node includes any one or more of: selectively puncturing transmission of LTE CRS symbols that overlap NR DMRS symbols in a downlink transmission time interval; selectively puncturing transmission of NR DMRS symbols that overlap LTE CRS symbols in the downlink transmission time interval; and selectively reducing a number of NR DMRS symbols transmitted to the UE in the downlink transmission time interval. In some embodiments, a method implemented in a UE includes identifying, in a downlink channel, subchannels containing NR DMRS symbols that are corrupted due to collision with LTE CRS symbols. For each identified subchannel: a respective time averaged channel estimate is determined based on NR DMRS symbols that are not corrupted due to collision with the LTE CRS symbols; and a respective MMSE weight is determined using the time averaged channel estimate.

    Abstract: Methods and apparatus for protecting a dynamic protection area (DPA). In one embodiment, an electronic device detects that the DPA is activated in the vicinity of a location recorded within a geolocation database. The electronic device compares a threshold representing acceptable interference and an estimated aggregate interference by the set of CBSDs to a set of points within the DPA. The electronic device moderates transmission by one or more CBSDs within the set of CBSDs when the estimated aggregate interference is higher than what is acceptable to the DPA.

  • Patent number: 10868643
    Abstract: Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to generate and/or transmit LTE information using LTE subcarriers located in unused portion(s) of the Wi-Fi system bandwidth independently of or in addition to transmitting Wi-Fi or LTE information using LTE subcarriers located in portions of the Wi-Fi system bandwidth normally occupied by Wi-Fi subcarriers.

  • Patent number: 10862723
    Abstract: Methods and systems for multi-protocol beacon operation in shared spectrum (unlicensed band) are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. In one application, an LTE transmitter (LTE-U) uses LTE subcarriers to generate an interpolated 802.11 (e.g. Wi-Fi) beacon transmission that can be understood by Wi-Fi receivers, for example to reserve the channel for a subsequent LTE transmission. For instance a W-LAN preamble is generated where STF and LTF fields consist in respectively 12 and 52 subcarriers mapped at their respective frequency locations among the 2048 LTE subcarriers with the remaining subcarriers set to 0. In some implementations, the use of beacons can be useful in implementations where it is desirable to gain prioritized access to reserve the channel.

  • Patent number: 10742464
    Abstract: Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, multi-protocol transmissions as described herein may be performed sequentially (e.g. in a time division multiplexing fashion) or concurrently (e.g. during the same or an overlapping time interval). For concurrent transmissions, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to use different subsets of the LTE subcarriers for concurrent LTE and 802.11 transmissions that can respectively be decoded by LTE and 802.11 receivers.
