  • Publication number: 20190379484
    Abstract: Blind detection of code rates for codes with incremental shortening involves determining a decoding code rate for decoding words that are based on codewords of a code that exhibits incremental shortening over a range of code rates. Incremental shortening is a code structure or coding property according to which different numbers of bits in encoding blocks that are to be encoded are set or frozen to a fixed value, to provide the range of code rates. This property enables blind detection of a decoding code rate, without explicit signaling or prior configuration of code rates between a transmitter and a receiver.

  • Patent number: 10506560
    Abstract: A method, apparatus and system for transmitting control plane messages in a communication network. Messaging is between two logical nodes, e.g. gNBs. Logical nodes include multiple networked sub-entities. Multiple sub-interfaces couple a pair of logical nodes. One sub-interface is selected based on keys associated with content of a message. Key-to-sub-interface associations are stored in memory. The keys may be identifiers included in the control plane message, such as UE IDs, Cell IDs, etc. Packets carrying the control plane message are configured and transmitted using the selected sub-interface. A key-to-sub-interface association may be established or updated when a control plane message is received via the sub-interface and includes the key, or in response to a rejection message specifying the correct sub-interface to use. A middle box entity may be provided in a logical node for each sub-interface and configured to act at least initially to forward messages to appropriate sub-entities.

  • Patent number: 10334535
    Abstract: A user equipment (UE) may compute uplink power control levels as a function of a downlink signal to noise ratio (SNIR). For example, the UE may determine an uplink transmit power level by summing a full power control (FPC) transmit power level, a product of a first adjustment factor (?) and the downlink SNIR, and a negative of a second adjustment factor (?2) when the product of the first adjustment factor (?) and the downlink SNIR is greater than or equal to the second adjustment factor (?2). A UE may also compute an uplink power control level as a function of target and/or current interference levels associated with neighboring base stations. A UE may also iteratively reduce a transmit power level until an interference level experienced by a neighboring base station has fallen below a threshold.

  • Patent number: 10225781
    Abstract: Spoofed radio control signaling instructions can be used to dynamically adapt management of the radio interface by radio control processors. More specifically, spoofed radio control signaling can be communicated to an accelerator application instantiated on a device-side of a radio control processor. The accelerator application can pre-process the spoofed radio control signaling before forwarding the instructions to a generic radio control processor. In one example, the generic radio control processor has a universal configuration that is capable of being adapted to different telecommunication protocols based on the spoofed radio control signaling. In another example, the spoofed radio control channel signaling is translated into control instructions at the accelerator application, which are forwarded to the generic radio control processor. The control instructions govern processing of downlink data channel transmissions and/or specify parameters of uplink transmissions.
