  • Patent number: 12088518
    Abstract: Provided is a wireless communication user equipment that wirelessly communicates. The wireless communication user equipment includes a communication module; and a processor configured to control the communication module. The processor is configured to receive a demodulation reference signal (DM-RS) of data channel and receive the data channel based on the DM-RS of the data channel, wherein a time-frequency resource mapped to the DM-RS is predetermined. When the time-frequency resource mapped to the transmission of the DM-RS of the data channel overlaps with the time-frequency resource mapped to a different purpose from the transmission of the DM-RS, the processor is configured not to receive the DM-RS in a resource element (RE) overlapping with the time-frequency resource mapped to the different purpose in the time-frequency resource mapped to the transmission of the DM-RS. The DM-RS is a reference signal specific to the wireless communication device.

  • Patent number: 9876727
    Abstract: A method for communication includes transmitting a sequence of outgoing data blocks from a network node over a communication link to a peer node, and receiving incoming data blocks from the peer node. A control field is added in a predefined location in each of the outgoing data blocks in the sequence by the network node. In at least a first subset of the outgoing data blocks in the sequence, the control field contains error control information, which is capable of causing the peer node to retransmit one or more of the incoming data blocks to the network node, while in at least a second subset of the outgoing data blocks in the sequence, disjoint from the first subset, the control field contains a flow control instruction, configured to cause the peer node to alter a rate of transmission of the incoming data blocks over the link.

  • Patent number: 9768860
    Abstract: A system and method for body channel communication is provided. The system includes a transceiver which encodes multiple bits per symbol when operating in a high data rate mode by selecting a first Walsh code in response to a first set of multiple bits of data and selecting a second Walsh code in response to a second set of multiple bits of data, both Walsh codes selected from a multiple-bit Walsh code sequence. The transceiver also generates a multi-level transmission signal having a predetermined symbol frequency by stacking the first Walsh code onto the second Walsh code, and transmits the multi-level signal having the first predetermined symbol frequency through the body channel. The transceiver also has additional modes of operation which include a normal mode and a low power mode, the low power mode decoding the multiple bits from the signal in response to harmonic energy from a harmonic frequency generated by the multiple-bit Walsh code sequence.

  • Patent number: 9742536
    Abstract: A base station includes a reference signal allocator that allocates a first layer of dedicated reference signals and a second layer of reference signals to the same resource elements in a first resource block. The reference signals are allocated to two adjacent resource elements corresponding to a first OFDM symbol and a second OFDM symbol on a first, second, and third subcarriers of the first resource block. The base station also includes a reference signal multiplexer that multiplexes the first layer with the second layer. A first cover code W1 is applied to the first layer. A second cover code W2, different from the first cover code, is applied to the second layer in a first and third subcarriers, and a variation of the second cover code W2? is applied to the second layer in a second subcarrier.

  • Patent number: 9736839
    Abstract: Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.
