Abstract: When a UE does not completely decode a packet transmitted from a base station, the UE may send ACK/NACK to the base station, upon which the base station may retransmit the packet based on the ACK/NACK. However, the ACK/NACK fails to provide the base station with information needed by the UE for completely decoding the packet. Accordingly, a method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a packet from a base station having a first MCS, determines information to provide to the base station, wherein the information comprises CQI relating to a channel condition and/or interference condition corresponding to time-frequency resources allocated for the received packet, and sends the information to the base station. Thereafter, the apparatus re-receives the packet from the base station, the re-received packet having a second MCS according to the information sent to the base station.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that different symbol durations coexist.

Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report indicating that a cooperative reception group including the UE and one or more other UEs connected to the UE over an out-of-band link supports one or more downlink transmit beamforming techniques. The UE may determine, based at least in part on the one or more downlink transmit beamforming techniques supported by the cooperative reception group, a downlink transmit precoder associated with relaxed beamforming nulling. The UE may decode a downlink transmission received from the base station based at least in part on the downlink transmit precoder and one or more decoded bits received from the one or more other UEs in the cooperative reception group. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping. In some implementations, a user equipment (UE) may receive a discovery reference signal (DRS) including a skipping signal identifying one or more UEs, may stay on an anchor channel when the skipping signal identifies the UE, and may switch from the anchor channel to a first downlink (DL) hopping channel of a DL frequency hopping pattern when the signal does not identify the UE. In some other implementations, a base station (BS) may be configured to output a DRS including a skipping signal identifying one or more UEs, output a signal indicating a channel occupancy time (COT) obtained on a first DL hopping channel of a DL frequency hopping pattern, and output DL data on the first DL hopping channel of the DL frequency hopping pattern.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a configuration for UE-to-UE sharing of a channel occupancy time (COT) and may transmit the configuration to a UE to indicate that it can share a UE-acquired COT with at least another UE. A UE may acquire a COT using a listen-before-talk (LBT) procedure, and if successful, may transmit a signal indicating that the COT is being shared with at least another UE. Additionally, a UE may receive a signal from another UE indicating that it has acquired a COT in a shared spectrum and that the COT is being shared with other UEs. The UE may perform a shortened LBT procedure within the COT, and if successful, may transmit an uplink transmission in the shared spectrum.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to design principles for extending Internet of Things (IoT) (e.g., narrowband IoT (NB-IoT), machine type communication(s) (MTC), etc.) into an unlicensed radio frequency (RF) band spectrum. In certain aspects, the method generally includes determining an interlace structure of tones, within an unlicensed radio frequency (RF) spectrum, available to a wireless node for communication, and communicating based on the interlace structure. In some aspects, the communicating involves hopping between tones within the interlace structure during different communication intervals.
