Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, for a master cell group and a secondary cell group used for a dual connectivity mode of the UE, information indicating physical downlink control channel (PDCCH) monitoring capability values for one or more of span-based monitoring or a combination of slot-based monitoring and span-based monitoring. The UE may receive, from the base station, PDCCH monitoring configuration values for the MCG and the SCG based at least in part on the PDCCH monitoring capability values. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating a beam switching pattern that indicates beams that are to be used by the UE on a per communication basis in a time domain. The UE may communicate with the base station based at least in part on receiving the information indicating the beam switching pattern. Numerous other aspects are provided.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A configuration to determine, by a user equipment, a random access procedure timeline, from multiple random access procedure timelines that each define a different duration between one or more messages that are communicated in a random access procedure can be determined or transmitted. A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or base station. The apparatus can select one or more rows or one or more columns in a DFT matrix, the one or more rows being even-numbered rows in the DFT matrix and the one or more columns being even-numbered columns in the DFT matrix. The apparatus can also determine an orthogonal matrix based on the one or more rows or the one or more columns in the DFT matrix, the orthogonal matrix having a size of (M×N)×(M×N) with M×N rows and M×N columns. Also, the apparatus can determine a codebook based on the orthogonal matrix, the codebook including a plurality of codepoints. The apparatus can also transmit at least one signal including a first codepoint of the plurality of codepoints in the codebook.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

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.
