  • Patent number: 10608786
    Abstract: An ordered number sequence may be determined based on an ordered sub-channel sequence specifying an order of N sub-channels that are defined by a code and that have associated reliabilities for input bits at N input bit positions. The ordered number sequence represents the ordered sub-channel sequence as a sequence of fewer than N numbers. The numbers in the ordered number sequence indicate the sub-channels, by representing numbers of the sub-channels for example, from different subsets of the N sub-channels, that appear in the order specified by the ordered sub-channel sequence. Using ordered number sequences, longer ordered sub-channel sequences could be constructed from smaller ordered sub-channel sequences, and/or sub-channels that to be selected from a longer ordered sub-channel sequence could be divided into two or more parts, with each part to be selected from shorter ordered sub-channel sequences.

  • Patent number: 10608770
    Abstract: A base station (BS) may transmit, and a user equipment (UE) may receive, a physical channel, such as a narrowband physical downlink control channel (NPDCCH) or a narrowband physical downlink shared channel (NPDSCH). In an interference-limited scenario in a network, it may be desirable to perform additional processing to introduce interference randomization into the control channel to ensure that the UE can recover data of the control channel. Some types of UEs, such as legacy UEs, may not be capable of recovering the control channel when the additional processing is performed. In some aspects, the BS may identify a type of UE associated with a cell, and may transmit a physical channel processed using a processing scheme selected based at least in part on the type of UE associated with the cell.

  • Patent number: 10601485
    Abstract: This specification provides a method of transmitting an uplink signal based on a codebook in a wireless communication system. More specifically, the method performed by a UE includes receiving, from a base station, downlink control information (DCI) including a first transmit precoding matrix indicator (TPMI), determining a codebook subset related to the transmission of the uplink signal based on the first TPMI, and transmitting, to the base station, the uplink signal based on the determined codebook subset. Accordingly, there is an advantage in that flexibility in the transmission antenna design of a UE can be increased because the degree of freedom of antenna port selection is increased.

  • Patent number: 10601480
    Abstract: Systems and methods are disclosed for utilizing unused bit resources to convey restrictions on parameters evaluated for a feedback report in a Multiple-Input Multiple-Output (MIMO) wireless communication system. In one embodiment, a method of operation of a transmitting node in a wireless network includes transmitting a feedback restriction indicator to a receiving node, where the feedback restriction indicator is an unused bit resource in one or more instances of a control channel that is indicative of one or more desired restrictions on parameters to be evaluated by the receiving node for a feedback report to be provided from the receiving node. The method of operation of the transmitting node further includes receiving the feedback report from the receiving node, where the feedback report is limited according to the feedback restriction indicator.

  • Patent number: 10601478
    Abstract: Methods and apparatus for selecting between downlink beamforming training and uplink beamforming training for hybrid beamforming. The decision whether to perform downlink beamforming training or uplink beamforming training for hybrid beamforming can be used by a network node to reduce training overhead and increase system capacity. A selection value is computed, indicative of the relative costs of signaling overhead for downlink beamforming training and uplink beamforming training to support downlink transmissions by the network node to the group of wireless devices using hybrid beamforming. The selection between uplink beamforming training and downlink beamforming training is based on the selection value.

    Abstract: Methods, systems, and devices for wireless communication are disclosed. Flexible interleaving configurations may be employed to support various operations, including beamforming. Flexible interleaving may include dynamically or semi-statically determining a combination of bit-level, tone-level, tone-group level, or other interleaving technique for one or more transmissions. The interleaving configuration may be based on delay spread, a coherence bandwidth, a signal to noise ratio, a Doppler spread, or a combination thereof. An interleaving configuration may be a determination may be made by a base station or some other network entity and explicitly signaled to another device. Additionally or alternatively, the determination may be made based on one or more implicit rules, which may be based on a variety of factors (e.g., available bandwidth, modulation and coding scheme (MCS), code block (CB) size). Further, interleaving may be enabled (or disabled) under certain conditions.
