Abstract: Aspects of the present disclosure relate to prioritized random access procedures in wireless systems. An exemplary method generally includes receiving, from a user equipment, a random access request including information identifying a type of a random access event being invoked, identifying one or more parameters associated with a backoff interval to be observed at the user equipment based, at least in part, on a priority associated with the type of the random access event, and transmitting, to the user equipment, a random access response including the identified one or more parameters.

Abstract: procedimentos de controle de acesso ao meio para indicações de índice de feixe. métodos, sistemas e dispositivos para comunicações sem fio são descritos. um equipamento de usuário (ue) pode selecionar um feixe de um conjunto de feixes e transmitir uma indicação do feixe selecionado em um elemento de controle de controle de acesso ao meio (mac) para estabelecer um link de comunicação com uma estação base. em alguns casos, o ue pode selecionar o feixe e indicar a seleção com base na identificação de uma falha de feixe e/ou determinar a realização de um procedimento de acesso aleatório. ao transmitir a indicação do feixe selecionado, o ue pode obter um recurso de uplink para a transmissão com base na disponibilidade do recurso de uplink. por exemplo, se o recurso de uplink estiver disponível, o ue pode transmitir a indicação do feixe selecionado multiplexado com uma transmissão de uplink. alternativamente, se o recurso de uplink não estiver disponível, o ue pode solicitar recursos de uplink para transmitir a indicação do feixe selecionado.

Abstract: os ues podem querer mudar para o estado de rrc ocioso ou para o estado de rrc inativo antes da expiração do temporizador ou sem ter que esperar que a rede libere a conexão de rrc. permitir que o ue aumente a taxa à qual faz a transição para o estado de rrc ocioso ou para o estado de rrc inativo pode permitir que o ue reduza o consumo de energia, bem como reduza os recursos de sinalização. o aparelho determina uma preferência entre uma transição para um estado de rrc inativo ou para um estado de rrc ocioso quando uma conexão de rrc é liberada. o aparelho envia, para uma estação base, uma indicação de preferência de estado de rrc da preferência de transição após a liberação da conexão de rrc do estado de rrc conectado para um estado de rrc inativo ou para o estado de rrc ocioso.

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: Some techniques and apparatuses described herein provide an indication of a result of decoding a two-step random access channel (RACH) message and an action to be performed by a user equipment (UE). For example, some techniques and apparatuses described herein may provide the indication using a UE contention resolution identity-based approach, wherein the contention resolution identity of the UE may be provided in a random access response. Some techniques and apparatuses described herein may use a fallback indicator that indicates the result of decoding and/or the action to be performed. Some techniques and apparatuses described herein may use a random access response (RAR) subheader that selectively omits a random access preamble identifier based at least in part on the result of decoding and/or the action to be performed.

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: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.
