  • Check positions within a transport block
    Patent number: 10469196
    Abstract: A radio node (52) in a wireless communication system (10) employs multiple different candidate formats (22) that define different possible positions of decoding checks (24) within a transport block of a specific size. The radio node (52) determines, from these different candidate formats (22), a format that defines a position of decoding checks (24) within a transport block (16) to be encoded or decoded. The radio node (52) then encodes or decodes at least a portion of the transport block (16) based on the determined format.

  • DECODING PARTIAL RADIO TRANSMISSIONS
    Publication number: 20190334662
    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.

  • Methods and arrangements relating to provision of beam coverage for a communication device operating in a wireless communication network
    Patent number: 10425898
    Abstract: Method by a communication device (120) for managing beam coverage. The device receives and evaluates (201) first reference signals transmitted by a network node. The first reference signals are comprised in first beams. The first beams are static or semi-static. The receiving and evaluating is according to a first state, wherein the device refrains from reporting back about the first reference signals. In response to the conclusion that all of the first reference signals are too weak and/or of too low quality by comparison to a threshold, the device sends (202) a request to one or more network nodes (110, 111), requesting a certain procedure for providing, by beamforming, one or more second beams (127, 128) specifically to target the device. The second beams (127, 128) comprise one or more second reference signals. The device switches, to a second state. wherein the device actively participates in the provision of beam coverage and is in a battery-saving mode.

  • Methods and apparatus for precoding control in a wireless communication network
    Patent number: 10419098
    Abstract: Culling a set of precoders down to a smaller set using a comparatively simple first-pass evaluation allows a wireless device or other entity to reduce an overall computational burden associated with identifying a currently preferred precoder. An example approach involves selecting a reduced set of precoders from a full set of precoders, based on performing preliminary evaluations of precoders in the full set, and selecting a preferred precoder or precoders from the reduced set, based on performing further evaluations of precoders in the second set. On a per precoder basis, the further evaluations are more complex than the preliminary evaluations. One may view the approach as using less complex first-pass evaluations to reduce the precoder search space, and then using more complex second-pass evaluations to identify a currently preferred precoder or precoders within the reduced search space.

  • First network node, second network node and methods for transmitting and receiving a protocol data unit
    Patent number: 10396931
    Abstract: A method performed by a first network node, for transmitting a RLC UM, PDU, to a second network node is provided. The first network node and second network node operate in a wireless communications network. When detected that the RLC UM PDU has failed to be transmitted over a first channel, the first network node decides to redirect the RLC UM PDU to be transmitted over a second channel. The first network node divides the RLC UM PDU into two or more re-segmented RLC UM PDUs. The first network node then transmits the re-segmented RLC UM PDUs to the second network node over the second channel. Each re-segmented RLC UM PDU comprises the following indications: (a) that the re-segmented RLC UM PDU is re-segmented, (b) an order indicator related to the re-segmented RLC UM PDU, and (c) whether or not the re-segmented RLC UM PDU is a last re-segmented RLC UM PDU out of the two or more re-segmented RLC UM PDUs.

    Publication number: 20190207661
    Abstract: A method performed by a first radio node for determining one or more precoders for beamforming of reference signals is provided. The reference signals relate to Channel State Information, CSI, of a forward link channel from the first radio node to a second radio node. The first radio node receives (201) reverse link reference signals from the second radio node and estimates (202) a first quality value of the forward link channel based on the received reverse link reference signal. The first radio node then determines (203) one or more first precoders of respective one or more first ranks based on the reverse link reference signal and the estimated first quality value. When the one or more first precoders have been determined, the first radio node triggers (204) a first transmission of one or more first forward link reference signals to the second radio node. The one or more first forward link reference signals are beamformed according to the determined respective one or more first precoders.

  • Dynamic Precoding of Shared Reference Signals
    Publication number: 20190182008
    Abstract: A receiver apparatus receives a terminal-specific demodulation reference signal having a rank k and estimates an effective multi-layer channel response, using the received terminal-specific demodulation reference signal. The receiver demodulates first data symbols from first time-frequency resource elements, using the estimate of the effective multi-layer channel response and using a first symbols-to-virtual-antenna mapping matrix M to obtain nc modulation symbols from each of the first time-frequency resource elements, wherein nc>1 and wherein the first symbol-to-transmit-layer mapping matrix M has dimensions k by nc. The first data symbols are decoded to obtain downlink control information assigning second time-frequency resource elements to the receiver.
