Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive system information from a base station indicating at least one configuration rule for power control parameter setting for random access. The UE may measure one or more reference signals and may estimate a path loss of wireless communications between the base station and the UE based on the measured reference signals. The UE may select one or more parameters from one or more sets of parameters indicated in the configuration rule. The UE may select a first transmit power for a preamble of a random access message and a second transmit power for a payload of the random access message, based on the estimated path loss and the configuration rule for power control parameters and power ramping procedures. The UE may transmit the random access message according to the selected first and second transmit powers.

Abstract: SE DESCRIBEN MÉTODOS, SISTEMAS Y DISPOSITIVOS PARA COMUNICACIONES INALÁMBRICAS. LOS CÓDIGOS DE PROPAGACIÓN DE DOMINIO DE TIEMPO DE LA TRANSFORMADA DE FOURIER PRE-DISCRETA (DFT) PUEDEN APLICARSE PARA LA MULTIPLEXACIÓN DE UES PARA INFORMACIÓN DE CONTROL DE ENLACE ASCENDENTE (POR EJEMPLO, SOBRE RECURSOS COMPARTIDOS DE UNA RANURA DE ENLACE ASCENDENTE). POR EJEMPLO, SE PUEDE MULTIPLEXAR UN NÚMERO MODERADO DE UES DENTRO DEL MISMO INTERVALO HACIENDO QUE CADA UE EXTIENDA SÍMBOLOS DE MODULACIÓN ANTES DE LA PROPAGACIÓN DFT POR UN CÓDIGO DE PROPAGACIÓN DIFERENTE. PARA LA ORTOGONALIDAD ENTRE LOS UES, LOS CÓDIGOS DE PROPAGACIÓN PRE-DFT PUEDEN SELECCIONARSE COMO CÓDIGOS DE COBERTURA ORTOGONALES (OCC). LAS SECUENCIAS DE PROPAGACIÓN PUEDEN GENERARSE A PARTIR DE UN CONJUNTO DE CUALQUIER SECUENCIA ORTOGONAL O GENERARSE A PARTIR DE MATRICES UNITARIAS. EN ALGUNOS CASOS, LA ORTOGONALIDAD EN EL DOMINIO DEL TIEMPO PUEDE MANTENERSE, ASÍ COMO UNA ESTRUCTURA MULTIPLEXADA POR DIVISIÓN DE FRECUENCIA (FDM) EN EL DOMINIO DE LA FRECUENCIA. PARA DICHA PROPIEDAD, SE PUEDE UTILIZAR UN DISEÑO OCC BASADO EN FOURIER. EN ALGUNOS OTROS EJEMPLOS, SE PUEDE UTILIZAR UN DISEÑO OCC BASADO EN MATRIZ DE HADAMARD.

Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.

Abstract: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.

Abstract: Methods, systems, and devices for wireless communication are described for defining uplink control channel resources and mapping uplink control channel resources to a user equipment (UE). Approaches described herein include identifying a physical uplink control channel (PUCCH) format to be used for a subsequent PUCCH transmission by the UE, identifying a PUCCH resource mapping rule based at least in part on the PUCCH format, and determining an uplink transmission resource to be used for the subsequent PUCCH transmission based at least in part on the PUCCH resource mapping rule. The PUCCH resource mapping rule may be explicit and/or implicit.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time- frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.
