  • Patent number: 10694506
    Abstract: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing overhead of retransmission control signaling. Where a retransmission control method is employed with 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>?, two bits are set. In a case where the encoding rate ?<R??, one bit is set. On the other hand, in a case where R??, zero bits is set.

  • Patent number: 10554248
    Abstract: A Global Navigation Satellite System (GNSS) receiver demodulates code shift keying (CSK) data utilizing correlations with combinational pseudo-random noise (PRN) codes generated for different bit positions. The GNSS receiver receives a signal including a PRN code modulated by CSK to represent a symbol (i.e., CSK modulated symbol). The GNSS receiver maintains a plurality of receiver codes, each representing a different shift in chips to the PRN code. The GNSS receiver performs a chip-by-chip linear combination of a group of receiver codes for each bit position of the CSK modulated symbol. The GNSS receiver correlates the received signal with each combinational PRN code to produce a binary value that is the CSK modulated symbol.

  • Patent number: 10548094
    Abstract: A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

  • Patent number: 10530539
    Abstract: Certain embodiments described herein use variable RTT for HARQ operations. Uplink HARQ may include, for example, for a first synchronous HARQ process, a UE selects first downlink resources to monitor for first HARQ feedback based on the first HARQ RTT value, and generates a first HARQ retransmission for first uplink resources in response to the first HARQ feedback. For a second synchronous HARQ process, the UE select second downlink resources to monitor for second HARQ feedback based on the second HARQ RTT value, and generates a second HARQ retransmission for second uplink resources in response to the second HARQ feedback. In certain embodiments, a RAN node signals or indicates the variable RTT values to the UE.

  • Patent number: 10492169
    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless devices (e.g., dual subscriber identity modules (SIM) devices) may support two subscriptions such that while one subscription is actively transmitting or receiving, the other subscription is put on standby. The wireless device may identify collisions in time between monitored paging messages associated with the first and second subscriptions. Accordingly, the wireless device may modify a radio access technology (RAT) priority setting for one of the subscriptions, such that paging messages may be received via a RAT different that the RAT used for the other subscription (e.g., following a cell reselection procedure performed according to the modified RAT priority). Operation using a modified RAT priority setting may be referred to as a fallback mode, which may be exited upon expiration of a timer. Additionally, discontinuous reception (DRX) durations associated with the RATs used for subscription paging may be reduced.

    Abstract: Aspects of the present disclosure provide methods and devices for multiple access downlink transmissions from a network side component to one or more User Equipment (UE) or multiple access uplink transmissions from two or more UEs to a network side component. In a downlink direction, a network side device generates, for each sub-carrier of the block of sub-carriers, a single constellation point from one or more bits of a multi-bit symbol, from each of multiple layers. In an uplink direction, each UE maps at least one bit from one or more layers of multi-bit symbols onto a subset of a block of sub-carriers. The two or more UEs collectively transmit on the block of sub-carriers.
