Abstract: Certain aspects of the present disclosure relate to methods and apparatus for management of hybrid automatic repeat request (HARQ) log likelihood ratio (LLR) and reordering buffers in wireless communication systems. According to certain aspects, a method for reducing buffer overhead that may be performed by a wireless node is provided. The method generally includes receiving one or more packets of at least one of an initial transmission or a retransmission; forming one or more log likelihood ratios (LLRs) based on the one or more packets; compressing the one or more LLRs by quantizing the one or more LLRs; and buffering the one or more compressed LLRs.

Abstract: Aspects presented herein may enable a wireless device (e.g., a joint FMCW radar and communication system) to transmit and/or receive an FMCW signal and an OFDM signal using the same time and frequency resources. In one aspect, a first wireless device receives an indication of a scheduled transmission for an FMCW waveform via a set of time-frequency resources. The first wireless device transmits or receives the FMCW waveform via the set of time-frequency resources based on the indication, where the FMCW waveform is separated from an OFDM waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the FMCW waveform and the OFDM waveform.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Aspects presented herein provide a low PAPR waveform design based on resource spreading, pulse shaping, and/or dynamic MCS configuration, such that a transmitting wireless device may set IBO of its PA closer to the saturation point of the PA to enhance the PA efficiency. In one aspect, a first network node receives waveform information from a second network node, where the waveform information includes at least one of: one or more first parameters associated with a first waveform type or one or more second parameters associated with a second waveform type. The first network node processes data based on the one or more first parameters associated with the first waveform type or the one or more second parameters associated with the second waveform type. The first network node transmits a waveform based on the processed data, where the waveform is the first waveform type or the second waveform type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a resource allocation, from a resource set, for a response message using a resource allocation selection procedure. In some aspects, the user equipment may transmit the response message using the resource allocation and based at least in part on determining the resource allocation. In some aspects, the user equipment may determine, using an implicit resource mapping procedure and before a radio resource control connection establishment, a resource allocation for a redundancy scheme response message based at least in part on a remaining minimum system information (RMSI) value. Numerous other aspects are provided.

Abstract: Disclosed are techniques for transmitting and processing reference signals for positioning estimation over a multipath multiple-input multiple-output (MIMO) channel. In aspects, a first node configures first and second reference signal resource sets for transmission of first and second sets of reference signals, wherein the first and second reference signal resource sets occur on first and second subbands of, and/or during first and second time intervals on, the MIMO channel, wherein each reference signal resource in the first and second reference signal resource sets utilize at least first and second MIMO precoders, and transmits, to a second node over the MIMO channel, the first and second sets of reference signals, wherein the first node transmits the first and second sets of reference signals to assist the second node to perform a positioning measurement based on joint processing of the first and second sets of reference signals.

Abstract: An apparatus may utilize an air interface to transmit and/or receive a transmission during a first TTI that includes a second set of data overriding a first set of data scheduled for transmission during the first TTI. The air interface may further be utilized to transmit and/or receive a transmission during one or more additional TTIs that includes a third set of data in a data portion of a subframe, and an override indicator that is at least partially embedded in the data portion. The override indicator may be configured to indicate that the first set of data scheduled for transmission during the first TTI is overridden by the second set of data having the higher priority. The override indicator may be transmitted after the second set of data is transmitted. The one or more additional TTIs may be after the first TTI.

Abstract: Aspects of the present disclosure provide methods and apparatus for beam selection in uplink-based and downlink-based mobility scenarios, for example, for new radio (NR) systems which can improve handover reliability, reduce handover frequency, and improve power efficiency. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes transmitting an uplink reference signal with an indication of a preferred downlink beam and receiving a downlink transmission based, at least in part, on the uplink reference signal.

Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.
