Abstract: Apparatus, methods, and computer-readable media for facilitating distribution matching via reversed compression are disclosed herein. An example method for wireless communication at a wireless transmitter includes decompressing a first sequence of information bits for wireless transmission to output a sequence of shaped symbols. The example method also includes compressing the sequence of shaped symbols to output a second sequence of compressed information bits.

Abstract: Methods, systems, and devices for wireless communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support modem control using millimeter wave (mmW) energy measurement. Generally, the described techniques provide for wireless device (e.g., wireless repeater) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may perform relay operations (e.g., amplification and forwarding operations) for communications between a base station and a UE in some channel (e.g., in a mmW channel). The wireless repeater may use energy measurements in the channel (e.g., analog mmW measurements) to control or configure a digital interface for monitoring out of band control information (e.g., in a sub-6 gigahertz (GHz) channel). For example, a wireless repeater may use energy measurements of signals transmitted by devices in a mmW band to configure (e.g., turn on) a digital interface of another modem to monitor for control information in a sub-6 GHz band.

For example, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, smart repeater, etc.) operation in a low power state, and base station signaling for triggering of wireless repeater control interface configuration. For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a low power state or a slow state (e.g., according to a long monitoring periodicity relative to a monitoring periodicity associated with a full power state or fast state). Upon detection of triggering signal from a base station, the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a short, or more frequent, monitoring periodicity relative to a monitoring periodicity associated with a low power state).

Abstract: Methods and apparatus for implementing a repeater are described. In various embodiments the repeater determines uplink/downlink timing information either from information broadcast from a base station or from monitoring received signals and/or gaps between received signals. In various embodiments while the repeater may decode control information to determine uplink/downlink time periods, user data is not decoded and re-encoded. In various embodiments interference between uplink and downlink circuitry is reduced or minimized by controlling gains, combining weights and/or power to amplifiers in the repeater based on the mode of operation. A stored information can include sets of different weights and/or parameters for the mode of operation and/or beam forming antenna pattern in use at a given time.

Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a base station of a wireless communications system to determine a configuration for a repeating device to forward signals to another device. In some examples, the configuration may be based on a number of repeating devices in the wireless communications system. The base station may also transmit a message for the repeating device to forward. In some examples, based on a buffering capability of the repeating device, the base station may transmit the message with a zero time offset relative to the control signaling. The repeating device may receive and process the control signaling and receive and buffer the message. In response to processing the control signaling, the repeating device may transmit the buffered message to another device. Implementing aspects of present disclosure may enable an increased efficiency of forwarding in wireless communications systems.

Abstract: Methods and apparatus for selecting a beam mode and/or beam for communicating with one or more devices are described. The beam mode selection may be and sometimes is between a broad beam mode of operation and a narrow beam mode of operation with respect to a particular device. Communication with one or more device may happen at a given time with the preferred beam mode and/or choice for an individual device sometimes being replaced with a beam mode and/or beam choice which is preferable from an overall system perspective, e.g., because it allows data transmission and/QoS requirements to multiple devices to be supported better than would be achieved if the preferred beam mode and/or beam selection made with respect to an individual device was used. The beam mode and/or beam selected for traffic data communication sometimes is different from the beam mode and/or beam used for communicating control channel information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relay/repeater unit (RU) in an integrated access/fronthaul (IAF) network, receives, from an upstream node, a first physical downlink control channel (PDCCH) message associated with a scheduled physical uplink control or shared channel (PUXCH) transmission from a downstream node at a scheduled time, and relays or repeats the first PDCCH message to the downstream node. If the scheduled PUXCH transmission associated with the first PDCCH message is not received from the downstream node at the scheduled time, the RU sends a negative acknowledgement (NACK) message associated with the scheduled PUXCH transmission to the upstream node. The RU may also or alternatively generate a second PDCCH message associated with a rescheduled PUXCH transmission and send the second PDCCH message to the downstream node.

The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.
