Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an increased bandwidth configuration for an enhanced physical uplink control channel (ePUCCH) based at least in part on an ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses a plurality of contiguous resource blocks (RBs) for the ePUCCH; and transmit the ePUCCH using the increased bandwidth configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for applying a beam switch interruption time across one or more active component carriers. In some cases a UE may be able to detect an actual overlap condition in which two physical downlink control channels (PDCCHs) monitoring occasions with different beam parameters overlap in time or a soft overlap condition in which a distance between the two PDCCH monitoring occasions in time is less than a threshold value; and to apply a prioritization rule to determine which of the PDCCH monitoring occasions to monitor for PDCCHs in response to detect the actual overlap or a soft overlap (e.g., almost immediately in contact in time or the gap is very small compared to the slot size).

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.

Abstract: A random access channel (RACH) procedure allows a user equipment (UE) to achieve synchronization with a network and obtain network resources and services from a scheduling entity. This disclosure provides various options for implementing a two-step RACH procedure that can support various UE behaviors in relation to using or not using a time symbol gap between a physical random access channel (PRACH) resource and a physical uplink control channel (PUCCH) resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that schedules a search space set; receive, on the search space set, first downlink control information (DCI) that schedules or configures one or more second DCIs that are multiplexed with one or more semi-persistent scheduling occasions; and process the one or more second DCIs based at least in part on the first DCI. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, from a base station, a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, receiving, from the base station, the one or more repetitions of the downlink control channel, and combining the one or more repetitions of the downlink control channel to decode the downlink control channel. In another aspect, the network can transmit, to a user equipment (UE), a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, and transmitting, to the UE, the one or more repetitions of the downlink control channel over the resources.

Abstract: Aspects of the present disclosure relate to a technique for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). A user equipment (UE) may receive and/or detect a downlink control information (DCI) that schedules at least one dynamic CORESET and indicates a TCI state from a list of one or more TCI states for the dynamic CORESET. The UE may apply the indicated TCI state for processing physical downlink control channel (PDCCH) transmissions in the dynamic CORESET when one or more conditions are met.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform an initial random access channel (RACH) attempt by transmitting, to a base station, an initial request message of an initial two-step RACH procedure; and perform an additional RACH attempt, using an alternative two-step RACH procedure, based at least in part on determining that an initial response message, corresponding to the initial request message, of the two-step RACH procedure is not received during an initial random access response window. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing transmit power control. In one aspect, a wireless device may receive a message including a path loss value and may transmit a signal to a UL Rx point using an uplink transmit power associated with the received path loss value. In another aspect, a wireless device may receive a reference signal, and a message including an offset value, and may transmit a signal to a UL Rx point using an uplink transmit power including a downlink path loss value associated with the reference signal minus the offset value. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement, or an offset value associated with the received power measurement

Abstract: A channel state information reference signal configuration (CSI-RS configuration) indicates a period and a plurality of offsets. For example, a base station may send a channel state information reference signal (CSI-RS) to a wireless communication device (e.g., a user equipment) according to the period and at least one of the offsets indicated by the CSI-RS configuration.
