  • Patent number: 11129144
    Abstract: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3<R?2/3, one bit is set. On the other hand, in a case where R?1/3, zero bits is set.

Transmitters operating according to the present disclosure use a per TRP rate matching technique in which the rate-matching order is to first rate-match across spatial layers transmitted by a TRP, then across frequency, then across time, and then to another TRP, where remaining data is rate-matched across the spatial layers of that other TRP, then across frequency, and then across time. The described per TRP rate-matching technique causes code blocks of a transport block to be transmitted by one TRP, instead of each code block being transmitted by a group of TRPs.

  • Patent number: 10790939
    Abstract: Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include detecting a condition of a device; selecting, based at least in part on the condition of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

    Abstract: Physical random access channel (PRACH) configuration on new radio unlicensed (NR-U) networks is disclosed. A UE may perform PRACH transmission either with a transmission opportunity (TXOP) or outside of a TXOP. The UE monitors for a control signal, such as a preamble or common control signal, identifying a TXOP. The UE may obtain an autonomous random access configuration for communications outside of the current TXOP that identifies a random access slot includes a plurality of random access occasions. If the UE fails to detect the control signal, it transmits an autonomous random access signal in a random access occasion corresponding to a beam direction of its location in relation to the base station. Otherwise, upon detection of the control signal and receipt of a trigger signal, the UE may transmit a random access request within the TXOP.

  • Patent number: 10686861
    Abstract: A method for a live stream connector includes receiving an input media stream of data with input parameter and transmitting, to a receiving node, the input media stream as packetized data with a header indicating the input parameters. The receiving node is configured with a receiving buffer based on the input parameters of the header and is configured to emit the packetized data to a destination when an amount of delay since receipt of the packetized data satisfies the latency input of the input parameters. The method further includes receiving, from a feedback node, a control packet identifying a missing packet within the transmission. The method also includes identifying that a retransmission buffer includes the missing packet and determining whether a sender buffer includes the identified missing packet. When the sender buffer includes the identified missing packet, the method includes retransmitting the identified missing packet to the receiving node.
