Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a remote radio head (RRH), a protocol configuration, wherein the protocol configuration configures the RRH to perform one or more MAC protocol layer functions of the UE. The UE may perform a communication, wherein one or more higher layer functions associated with the communication are performed by the UE, wherein the one or more higher layer functions are associated with a higher layer than the MAC protocol layer. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a base station (BS), an indication of a random access (RA) channel (RACH) preamble. The RACH preamble is a member of a first set of RACH preambles reserved for positioning purposes, the first set of RACH preambles is different from a second set of RACH preambles reserved for communication purposes, and the first and second sets of RACH preambles are associated with the BS. The UE detects, while in a radio resource control (RRC) idle or RRC inactive state, a positioning event. The UE transmits, to the BS, the RACH preamble. The UE receives, from the BS, a RA response for positioning purposes that is different from a RA response for communication purposes, the RA response for positioning purposes including a random access preamble identifier that is mapped to the RACH preamble.

Abstract: A user equipment includes a processor configured to: receive a first, second, and third reference signals including a first, second, and third sets of tones, and spanning first, second, and third frequency ranges in first and second sets of symbols and at least one third symbol, respectively, the first and second frequency ranges differing: where at least one of (1) the third frequency range overlaps the first frequency range, or (2) the at least one third symbol overlaps with the first set of symbols and the third frequency range overlaps the second frequency range; determine an offset between the first reference signal and the supplemental signal using the third set of tones; and determine a first indication, of a time and/or a range, based on a combination of the first reference signal and the second reference signal using the offset.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: Aspects presented herein may improve the power control of a communication device in an ultra wide bandwidth beamforming systems. Aspects presented herein may enable the communication device to adjust one or more parameter of a power control loop based the sub-band used within a BWP or based on the channel used within a channelized frequency band. In one aspect, a UE receives at least one power control parameter for transmitting one of a first PUSCH, a first PUCCH, or a first SRS to a base station. The UE transmits the one of the first PUSCH, the first PUCCH, or the first SRS at a first power based on a first sub-band within a BWP.

Abstract: A method of wireless communication performed by a first transmission device includes determining a set of spectrum sharing parameters based on sensing performed during a sensing period of a current time slot in a fixed contention based spectrum sharing system. The first transmission device shares a spectrum with a second transmission device. The method also includes determining, at a first artificial neural network of the first transmission device, a transmission device action, and/or a transmission parameter in response to receiving the set of spectrum sharing parameters. The method further includes transmitting, from the first transmission device, to a first receiving device during a data transmission phase of the current time slot based on the transmission device action and/or the transmission parameter.

Abstract: A user equipment (UE) provides to a location server a recommendation or request for positioning technologies and methods that may be appropriate for the environment in which the UE is located. The UE may provide the recommendation or request may be a priority list of one or more specific positioning technologies, one or more specific methods of a positioning technology, a combination thereof. The UE based prioritization for positioning may be provided unsolicited or requested by the location server. The UE based prioritization for positioning may be provided as part of a message used in current positioning protocols, such as Long Term Evolution (LTE) Positioning Protocol (LPP), e.g., by ranking information elements (IEs) associated with each positioning technology and method in the body of the message or as part of a common IE.
