Abstract: UEs may want to switch to the RRC idle state or to the RRC inactive state sooner than the expiration of the timer or without having to wait for the network to release the RRC connection. Allowing the UE to increase the rate at which it transitions to RRC idle state or RRC inactive state may allow the UE to reduce power consumption, as well as reduce signaling resources. The apparatus determines a preference between a transition to an RRC inactive state or to an RRC idle state when an RRC connection is released. The apparatus sends, to a base station, an RRC state preference indication of the preference for transitioning upon release of the RRC connection from the RRC connected state to one of the RRC inactive state or to the RRC idle state.

Abstract: Métodos, sistemas y dispositivos para comunicaciones inalámbricas. Un equipo de usuario (UE) puede seleccionar un haz de un conjunto de haces y transmitir una indicación del haz seleccionado en un elemento de control de control de acceso a medios (MAC) para establecer un enlace de comunicación con una estación base. En algunos casos, el UE puede seleccionar el haz e indicar la selección basándose en la identificación de una falla de haz y/o la determinación de la realización de un procedimiento de acceso aleatorio. Al transmitir la indicación del haz seleccionado, el UE puede obtener un recurso de enlace ascendente para la transmisión basándose en la disponibilidad del recurso de enlace ascendente. Si el recurso de enlace ascendente está disponible, el UE puede transmitir la indicación del haz seleccionado multiplexado con una transmisión de enlace ascendente. Alternativamente, si el recurso de enlace ascendente no está disponible, el UE puede solicitar recursos de enlace ascendente para transmitir la indicación del haz seleccionado, multiplexado con una transmisión de enlace ascendente. Alternativamente, si el recurso de enlace ascendente no está disponible, el UE puede solicitar recursos de enlace ascendente para transmitir la indicación del haz seleccionado.

Abstract: This disclosure relates to methods, devices, and systems for wireless communications, and more particularly to aggregating physical uplink shared channel (PUSCH) resource units relating to a random access message. A user equipment (UE) may identify a random access message of a random access procedure. The random access message may include a random access preamble and a random access payload. The UE may aggregate multiple PUSCH resource units of a set of PUSCH resource units associated with one or more PUSCH occasions (POs) based on one or more of a payload size of the random access payload or a modulation and coding scheme associated with the random access payload. As a result, the UE may transmit the random access payload of the random access message on a PUSCH using time and frequency resources of the aggregated multiple PUSCH resource units over the one or more POs.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving signaling from a base station to activate a semi-persistent scheduling (SPS) configuration for transmission between the base station and the UE, and receiving a hybrid automatic repeat request (HARM) timing for downlink transmissions based at least in part on the SPS configuration being activated. In another example, the method includes establishing a connection with a base station using a component carrier (CC), the CC having a plurality of bandwidth parts (BWPs), receiving signaling that indicates an SPS configuration or other types of pre-configured resources associated with at least a first BWP of the plurality of BWPs and transmitting or receiving using at least the first BWP according to the SPS configuration or other types of pre-configured resources associated with at least the first BWP.

Abstract: Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths and transmitting packets based on the determined weights. In one implementation the method includes sorting packets at least according to one of size type and nature of the data in the packets. Accordingly sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation sorting the packets includes deep packet inspection to determine a respective priority value for each packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may transmit a random access message including a preamble and a payload. A base station may detect the preamble of the random access message. The base station, and may fail or succeed to decode the payload of the random access message. The base station may transmit, based at least in part on detecting the preamble and the different decoding outcome for the payload, a random access response. The random access response may include an uplink group grant and an indication for a type of the uplink group grant for a plurality of UEs whose preamble transmission share the same time and frequency occasion. UEs may monitor the type and the contents of the uplink group grant and transmit data subsequently on a set of shared time frequency resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration message from a base station for supporting random access channel (RACH) type selection by the UE. The configuration message may include one or more reference signals and one or more link quality thresholds corresponding to the one or more reference signals. The UE may generate measurements of the reference signals and determine link quality for communications between the UE and the base station based on the measurements. Based on a comparison between the link quality to corresponding link quality thresholds, the UE may select a two-step random access procedure, a four-step random access procedure, or both for establishing a connection with the base station. In some cases, the UE considers system loading information, transmission parameters, or random access rules in selecting the random access procedure.

Abstract: Aspects presented herein provide an enhanced power management solution, such that an apparatus may configure a UE with more than one DRX configuration for different cells. The apparatus determines a configuration of a plurality of discontinuous reception (DRX) groups for communicating with a UE. The apparatus configures the UE with a first DRX group for a first set of serving cells. The apparatus configures the UE with a second DRX group for a second set of serving cells.
