  • Patent number: 10924417
    Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: predicting an upcoming communication content in a current channel based on learning input data from a plurality of sources relevant to a communication activity of a user. A user response to the predicted content is assessed and a communication channel model for the factors including the input data is selected. A user satisfaction level with the current channel is checked against a predefined threshold for the selected communication channel model. For the current channel that is less than satisfactory, an adaptive action is taken to adapt the current channel to another for the user.

  • Patent number: 10869350
    Abstract: A first radio station (1) requests or instructs a second radio station (2) to prepare for communication with a radio terminal (3) on a second cell (20) while a first radio connection on a first cell (10) with the radio terminal (3) is established. Further, the first radio station (1) instructs the radio terminal (3) or the second radio station (2) to establish a second radio connection on the second cell (20) with the radio terminal (3) while maintaining the radio connection on the first cell (10) with the radio terminal (3). It is thus for example possible to enable a single radio terminal to establish radio connections with cells of a plurality of radio stations, in order to achieve carrier aggregation of cells operated by different radio stations.

  • Patent number: 10855405
    Abstract: Various aspects of the disclosure relate to retransmission techniques for communication of information (e.g., for wireless communication). In some aspects, if a device's first transmission including encoded data and parity information (subject to puncture) fails, the device's retransmission (e.g., in response to a NAK) involves transmitting the parity information that was punctured. In some aspects, the coding rate used for encoding the data for the first transmission is selected to meet an error rate (e.g., a block error rate) for the second transmission. The second transmission may also include repetition information that includes the encoded data. The repetition information could also include at least a portion of the encoded parity information.

  • Patent number: 10833908
    Abstract: In a broadband wireless communication system, a spread spectrum signal is intentionally overlapped with an OFDM signal, in a time domain, a frequency domain, or both. The OFDM signal, which inherently has a high spectral efficiency, is used for carrying broadband data or control information. The spread spectrum signal, which is designed to have a high spread gain for overcoming severe interference, is used for facilitating system functions such as initial random access, channel probing, or short messaging. Methods and techniques are devised to ensure that the mutual interference between the overlapped signals is minimized to have insignificant impact on either signal and that both signals are detectable with expected performance by a receiver.

  • Patent number: 10813119
    Abstract: A terminal device receives first information including an acknowledgment resource indicator (ARI), and determines, based on the ARI, a first uplink control channel (PUCCH) resource in a PUCCH resource set corresponding to a payload size of a hybrid automatic repeat request acknowledgment (HARQ-ACK). In a case that the first PUCCH resource and a second PUCCH resource partially overlap in terms of time; or the first PUCCH resource and a second PUCCH resource configured for CSI do not overlap in terms of time, and the first PUCCH resource and the second PUCCH resource each partially overlap at least one third PUCCH resource configured for at least one positive scheduling request (SR) in terms of time, the terminal device determines, based on the ARI, a fourth PUCCH resource in a second PUCCH resource set corresponding to a total payload size for sending the HARQ-ACK, CSI, and at least one SR status.

  • Patent number: 10805437
    Abstract: A method of configuring a forwarding element that includes several data plane message processing stages. The method stores a set of action codes in an instruction memory in the data plane of the forwarding element. Each action code identifies an operation to perform on a field of a message received at the data plane. The method determines action codes required to process each field of the message in each message processing stage. The method configures a data-plane processing unit of the forwarding element to concurrently perform a group of the action codes in the same data plane processing stage when (i) the action codes are the same and (ii) operate on the same field of the message.
