Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, via a communication link between the first UE and a base station, radio resource control (RRC) signaling which configures a relay communication sidelink for communicating message traffic between the first UE and a second UE for relay to the base station. The first UE may receive a control message via layer one (L1) signaling or layer two (L2) signaling which activates the relay communication sidelink configured by the RRC signaling. The first UE may then communicate, via the relay communication sidelink, a message for relay to or from the base station by the first UE or the second UE based on the control message.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a narrowband (e.g., a single carrier, anchor carrier, etc.) for a control message that includes a grant for downlink data transmissions. The narrowband containing the control message may be a portion of a system bandwidth. The UE may then monitor a wideband (e.g., all or multiple carriers of the system bandwidth) for data according to the control message. Monitoring the wideband may include additional or alternate circuitry being powered (e.g., receiver circuit switching) to enable reception on an increased range of frequency spectrum. In some examples, a gap or narrowband data transmission may be scheduled between the control message and the grant to allow grant processing and receiver circuitry switching at the UE. In some cases, the control message and data transmission may be received in the same or different transmission time intervals (TTIs).

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum, and may transmit the configuration to at least one user equipment (UE) served by the base station. Additionally, a UE may receive a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum. The UE may detect at least one signature waveform of the set of signature waveforms, and in response to detecting the at least one signature waveform, operate in the micro-sleep mode for a period of time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a trigger signal indicating that a base station has obtained access to a shared radio frequency spectrum band. The UE may transmit, in response to the trigger signal, a trigger response signal configured to reserve a channel of the shared radio frequency spectrum band for a downlink transmission by the base station, where the trigger response signal is transmitted for a time period extending to a scheduled beginning of the downlink transmission. The UE may receive the downlink transmission after an expiration of the time period and based at least in part on the trigger signal.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support chained sidelink transmissions. A transmitting user equipment (UE) may send, to a receiving UE, sidelink control information (SCI) that reserves resources for transmission from the transmitting UE as well as reserves resources for a response transmission from the receiving UE. The receiving UE may respond with a transmission using the resources that were reserved in the SCI and without sending its own SCI to reserve resources for the response. The latency between the transmitting UE sending the first transmission and receiving a response from the receiving UE may be reduced, because the transmitting UE reserved the resources for itself and the receiving UE with the same SCI.

Abstract: Aspects relate to spectrum sharing for use in a wireless communication network that serves both prioritized and non-prioritized user access terminals. In one example, a user access terminal, e.g., a user equipment (UE), senses an amount of signal energy within a frequency band during one or more sensing intervals in response to a determination that the access terminal is a non-prioritized access terminal. If the amount of signal energy does not exceed a sensed energy threshold, the user access terminal transmits wireless signals following the sensing intervals. On the other hand, if the amount of signal energy exceeds the sensed energy threshold, the user access terminal modifies transmissions while the amount of signal energy sensed during one or more subsequent sensing intervals exceeds the sensed energy threshold. For example, the access terminal may delay or adjust transmissions until the amount of signal energy no longer exceeds the sensed energy threshold.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: Certain aspects of the present disclosure provide techniques for protecting overhead and common channel transmissions in a NR shared spectrum system. A BS of a first operator may receive information regarding at least one overhead transmission associated with a wireless device of a second operator and may protect one or more overhead signal transmissions of the wireless device based, at least in part, on the received information. A UE may detect information associated with at least one overhead transmission from a wireless device associated with a first operator and may transmit the information regarding the detected overhead transmission to a BS associated with a second operator. A UE served by a BS associated with a first operator may detect a wireless device (e.g., another UE or a BS) associated with a second operator. The UE may report an identification of the wireless device to the BS.

Abstract: According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.
