  • Methods, Network Nodes and User Equipments in a Wireless Network for Communicating an EPDCCH
    Publication number: 20210068089
    Abstract: A network node in a wireless communication network communicates an enhanced Physical Downlink Control Channel (ePDCCH) to a user equipment (UE). This begins with the transmission, to the UE, of a configuration message that indicates the mappings of ePDCCH onto resource elements for both a first ePDCCH set and a second ePDCCH set. The mapping for the first ePDCCH set avoids the use of resource elements already in use by a first type of signal (e.g., a Cell-Specific Reference Signal or CRS), whereas the mapping for the second ePDCCH set avoids the use of resource elements in use by a second type of signal. The choice of an ePDCCH set for transmitting data to a UE may then be dynamically made in order to avoid interference caused by the first or second types of signal.

  • Decoding partial radio transmissions
    Patent number: 10917201
    Abstract: According to some embodiments, a method in a radio network element of providing hybrid automatic repeat request (HARQ) feedback comprises receiving, from a wireless transmitter, a first set of coded bits. The first set of coded bits comprises a partial subset of coded bits to be received during a transmission time interval (TTI). The radio network element decodes the first set of coded bits; determines a first decoding indicator based on the success or failure of the decoding of the first set of coded bits; and communicates the first decoding indicator to the wireless transmitter. Particular embodiments communicate the first decoding indicator to the wireless transmitter within four TTI of receiving the first set of coded bits. Particular embodiments estimate a decoding indicator for the entire TTI based on the success or failure of the decoding of the first set of coded bits.

  • Discarding and retaining physical data channels
    Patent number: 10892874
    Abstract: A first channel for carrying Layer 2 messages carries data that will not be retransmitted and for which decoding-related information need not be retained by the receiving node in the event of an unsuccessful decoding of the data, while a second channel carries data that will be retransmitted in the event that a negative acknowledgement is received by the transmitting node. In an example method, first and second subsets of Layer 2 messages are received on first and second physical data channels, respectively. Decoding-related information for unsuccessfully decoded messages in the first subset is retained for use with subsequent retransmissions, while decoding-related information for unsuccessfully decoded messages in the second subset is discarded without waiting for retransmissions. Acknowledgements or negative acknowledgements are sent for messages in the first subset, but may or may not be sent for messages in the second subset, in various embodiments.

  • QUASI CO-LOCATED ANTENNA PORTS FOR CHANNEL ESTIMATION
    Publication number: 20210007091
    Abstract: Systems and methods are disclosed for estimating one or more channel properties of a downlink from a cellular communications network based on quasi co-located antenna ports with respect to the one or more channel properties. In one embodiment, a user equipment receives a downlink subframe including a downlink control channel from the cellular communications network. The user equipment estimates one or more large-scale channel properties for an antenna port of interest in the downlink control channel based on a subset of reference signals that correspond to antenna ports in the cellular communications network that are quasi co-located with the antenna port of interest with respect to the one or more large-scale channel properties. As a result of using the quasi co-located antenna ports, estimation of the one or more large-scale channel properties is substantially improved.
