  • 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.

  • Patent number: 10299203
    Abstract: According to an aspect of the teachings herein, dynamic cell activation uses the spectrum of a spectrum owner to provide wireless communication services in a location that may not be served by the spectrum owner. For example, a base station determines which one of two or more network operators is targeted by a wireless device requesting access, and correspondingly activates communication services for the device, using spectrum owned by the targeted network operator. Advantageously, the cell(s) may not be persistent and instead may be provided only when access is requested and then only in the spectrum of the targeted network operator(s). This approach offers power savings as compared to providing persistent cells for multiple network operators. Further, the contemplated arrangement makes it economic for third parties and network operators to use of operator-owned spectrum that might otherwise remain unexploited in the involved locations.

  • Patent number: 10291375
    Abstract: A network node, a User Equipment, UE and methods therein, for handling a message transmitted over a radio link. The network node generates a first set of identity check bits for a first part of the message, based on the message and a first check identity, and further generates a second set of identity check bits valid for a second part of the message, based on the message, the first set of identity check bits and a second check identity. The message is then transmitted over the radio link with the first and second sets of identity check bits attached. The UE performs a first verification check using the second set of identity check bits and the second check identity, and performs a second verification check using the first set of identity check bits and the first check identity. The UE then handles the second message part based on the first verification check and the first message part based on the second verification check.
