  • Patent number: 12267710
    Abstract: A method of downlink channel state information (DL CSI) computation and reporting is proposed to support high velocity in new radio (NR) systems. In a first novel aspect, two CSI reference slots are defined. CSI reference slot for CSI measurement is defined for determining which CSI-RS/SSB occasion(s) is used for computing CSI. CSI reference slot for CSI computation is defined for determining the slot where UE assumes the CSI computation should be based upon the channel at that time onwards. In a second novel aspect, UE can be configured with a CSI computation period consisting of one or N slots and can be divided into multiple sub-periods without overlap. UE can be configured to compute and report wideband CSI and subband CSI for the whole CSI computation period and/or for each sub-period.

  • Patent number: 12261616
    Abstract: Techniques for compensating high-speed digital-to-analog converters (DACs) for static mismatch are described. In ideal circumstances, the current sources of a DAC are identical to each other, leading to a frequency response presenting a relatively flat noise spectrum. In the presence of mismatch, however, the response creates unwanted spurious content, which can negatively affect the DAC's dynamic range. The techniques described herein involve randomized thermometric encoders. First, the direction in which a packet contracts or expands, depending on the value to be encoded, can be randomized. Second, pairs of values in a packet (and/or pairs of values outside the packet) can be swapped with one another in a randomized fashion. Third, the decision of whether to apply randomization or not can itself be randomized. By applying one or more of the randomization techniques described herein, the negative effects of switch timing offset and errors in DC linearity can be mitigated.

  • Patent number: 12262431
    Abstract: During association between an access point (AP) multi-link device (MLD) and a non-AP MLD, the non-AP MLD indicates a first capability allocation of a first combination of affiliated stations for a first combination of enabled links on the non-AP MLD, and indicates a second capability allocation of a second combination of affiliated stations for a second combination of enabled links on the non-AP MLD. For example, the first combination of affiliated stations and the second combination of affiliated stations have different numbers of stations in the non-AP MLD, and the first combination of enabled links and the second combination of enabled links have different numbers of enabled links. Hence, during the association between the non-AP MLD and the AP MLD, capabilities of different non-AP station combinations corresponding to different enabled link combinations supported by the non-AP MLD are signaled to the AP MLD.

  • Patent number: 12256371
    Abstract: Various schemes pertaining to optimization of distributed resource unit (RU) tone plans for peak-to-average power ratio (PAPR) reduction in 6 GHz low-power indoor (LPI) systems are described. An apparatus distributes a plurality of subcarriers of a RU over a bandwidth to generate a distributed-tone RU (dRU) or a distributed-tone multi-RU (dMRU). The apparatus then communicates with a communication entity using the dRU or the dMRU. In distributing the plurality of subcarriers of the RU to generate the dRU or the dMRU, the apparatus distributes the plurality of subcarriers of the RU with a predefined span over each 20 MHz frequency segment or subblock in the bandwidth and with a gap of at least a minimum size around a center direct-current (DC) tone in a distribution pattern of the plurality of subcarriers to result in reduction in a PAPR in communicating with the communication entity.
