Abstract: A wireless device receives one or more radio resource control (RRC) messages indicating a first downlink bandwidth part (BWP) of downlink BWPs of a cell, as a first active downlink BWP of the cell. The wireless device activates, based on the one or more RRC messages, the first downlink BWP of the downlink BWPs of the cell. The wireless device receives an RRC reconfiguration of the first active downlink BWP of the cell. The RRC reconfiguration indicates that a second downlink BWP of the downlink BWPs of the cell is the first active downlink BWP of the cell. In response to the RRC reconfiguration of the first active BWP of the cell, the wireless device switches to the second downlink BWP of the cell, as an active downlink BWP of the cell.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode a set of bits to transmit to a receiving device based on a repetition factor. The transmitting device may map, based on the repetition factor, the set of encoded bits to a subset of subcarriers such as adjacent subcarriers of a set of subcarriers. The transmitting device may generate a signal including the set of encoded bits based on the mapping, and transmit the generated signal to the receiving device. The receiving device may receive a modulated signal from the transmitting device, and identify, based on a repetition factor, a subset of subcarriers including adjacent subcarriers of a set of subcarriers associated with the modulated signal. The receiving device may average the subset of subcarriers including the adjacent subcarriers, and demodulate the modulated signal in accordance with the averaged subset of subcarriers including the adjacent subcarriers.

Abstract: An information mapping method includes mapping, by a transmitting end device, first information to second information on a delay-Doppler frame. The delay-Doppler frame includes M×N grids, M is the total number of delay indexes, N is the total number of Doppler indexes. The delay-Doppler frame includes at least two subframes, and each subframe includes a first guard interval portion, a first mapping portion, and two second mapping portions. The two second mapping portions occupy grids corresponding to kmax Doppler indexes at a head and a tail of the subframe in a Doppler direction, and the first mapping portion occupies grids corresponding to (N/G−2kmax) Doppler indexes of the subframe; G being the number of subframes in the delay-Doppler frame. Information mapped to second mapping portions at heads of different subframes is the same, and information mapped to second mapping portions at tails of different subframes is the same.

Abstract: Certain aspects of the present disclosure provide techniques for receiving an indication of variable tracking reference signal (TRS). A method that may be performed by a user equipment (UE) includes determining a configuration indicating a value for a variable tracking reference signal (TRS) density, monitoring for TRSs from a base station (BS) according to the indicated value for the variable TRS density, and performing at least one of frequency tracking or timing tracking based on the monitoring.

Abstract: A communication circuit supports a first communication protocol and a second communication protocol that is different from the first communication protocol. A number of signals include first signals conveying first information messages and second signals conveying second information messages. The first information messages include a repetitive message having fixed repeated content and the second information messages include a non-repetitive message having variable content. The first signals and the second signals are transmitted via the communication circuit using the first communication protocol for the first signals and the second communication protocol for the second signals.

Abstract: A method of calibrating a transmitter chain in a phased array system in which a lower guard band is assigned to a lower side of an operating carrier of a communication channel and an upper guard band is assigned an upper side of the operating carrier includes injecting a first calibration tone into the transmitter chain and detecting its arrival at the end of the transmitter chain, at which point a first detected calibration signal is generated. The first detected calibration signal and the injected first calibration tone are then compared to produce a first comparison signal. The transmitter chain's phase and/or gain is then adjusted based on this first comparison signal. The first calibration tone located within one of the lower and upper guard bands of the communication channel of the transmitter chain.
