Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

A MIMO ARC transmitter derives demux streams (15, 20) carrying different parts of the information, at given data rates, processes each demux stream by coding and modulation (25, 30) before transmission over the channels, and varies (50, 165) the coding or modulation according to channel conditions, and controls the data rates (50, 155) according to conditions of the channels independently of the variations in coding and modulation. The separate control of processing and of data rates for each demux stream can provide a better balance of rapid response to changing conditions and efficiency in less rapidly changing conditions. The frequency of updating the processing can be limited since these take more time to adapt in the receiver. Sensitivity to rapid changes can be achieved by the data rate changes since these involve less overhead than changes in the processing.

A method is provided for generating precoder data, comprising: obtaining transmit power data indicative of a transmit power of a plurality of multiple-input/multiple-output signals; obtaining signal quality data, the signal quality data including at least one measure of a quality of the plurality of multiple-input/multiple-output signals; obtaining channel data with respect to a wireless channel, the channel data including a measure of respective channel parameters of each of a plurality of channel paths in the wireless channel; constraining one or more system performance parameters; and determining first and second precoder diagonal values (wA and wB) based on the signal quality data, the transmit power data, the channel data, and the one or more constrained system performance parameters.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.

Methods and apparatus related to wireless terminal reporting alternative selection for a fixed bit size control information request report, e.g., a 4 bit uplink traffic channel request report, are described. A wireless terminal maintains a plurality of different request groups corresponding to uplink traffic to be transmitted. The same request report format includes a plurality of reporting alternatives, different reporting alternatives corresponding to different request groups. Backlog can and sometimes does exist simultaneously corresponding to request groups corresponding to different reporting alternatives. The wireless terminal uses priority information associated with the request groups having non-zero backlog to select a reporting alternative. In some embodiments, at least some of the request groups have priorities which are calculated by the wireless terminal and change as a function of determined transmission deadline information.

A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver; the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.

Provided are an information transmission method and device, and a storage medium. The information transmission method applied to a first communication node includes: sending feedback indication information to a second communication node according to configuration information or pre-configuration information, and receiving feedback information sent by the second communication node according to the configuration information or pre-configuration information and the feedback indication information.

Methods, systems, and devices for wireless communication are described. A wireless station (STA) may monitor characteristics of signaling with an access point (AP) in a wireless local area network (WLAN). If a characteristic of the signaling from the AP falls below a first threshold, the STA may transmit a feedback message in a first portion of a bandwidth and refrain from transmitting duplicate feedback messages in a second portion of the bandwidth. In some examples, the STA may enable or disable duplication for transmitting the feedback message based on a feedback message transmit power threshold. Additionally, or alternatively, the STA may monitor signaling on two connected transmission chains. Based on a coding rate threshold or a signal strength threshold, the STA may increase an output power of the chain with the lower signal strength to give an extra link budget for transmissions to the AP.

Methods and apparatuses for are NTN IoT HARQ disabling for HARQ bundling and multiple TB scheduling disclosed. A UE comprises a processor; and a transceiver coupled to the processor, wherein the processor is configured to receive, via the transceiver, a control signal scheduling transport block(s), where each of the transport block(s) is associated with an HARQ process with HARQ feedback enabling or an HARQ process with HARQ feedback disabling according to an HARQ indication; and receive, via the transceiver, the transport block(s) based on the control signal.

Techniques and devices for wireless communications are described. A user equipment (UE) may receive a first message from a network entity that indicates a configuration for reporting spatial domain basis function updates to the network entity. The UE may transmit a full channel state information (CSI) report and a partial CSI report to the network entity based on the indicated configuration. The full CSI report may indicate a set of spatial domain basis functions and the partial CSI report may indicate an update for the set of spatial domain basis functions. The update for the set of spatial domain basis functions may be relative to the full CSI report or a previously transmitted partial CSI report. In some examples, the UE may receive a second message from the network entity based on the partial CSI report.
