Abstract: Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Abstract: A wireless communication network includes a user equipment (UE) to receive a set of instructions, from a base station, to perform a simultaneous change of a set of current bandwidth parts (BWPs) to a set of new BWPs in a set of cells. The set of instructions schedules set of slots for the UE to receive and/or transmit a set of downlink and/or uplink signals via the set of new BWPs, respectively. The UE also determines a delay associated with performing the simultaneous change of the set of current BWPs to the set of new BWPs, respectively, and determines whether it is able to receive and/or transmit the set of downlink and/or uplink signals via the set of new BWPs in the set of slots satisfying the delay, respectively. A base station is also included to communicate with the UE to effectuate the aforementioned operation.

Abstract: Aspects described herein relate to receiving, from a serving cell, a configuration for performing conditional handover to one or more target cells, establishing, based on detecting a condition from the configuration, a connection with a target cell for performing handover to the target cell, and transmitting, based on establishing the connection with the target cell and based on determining that the conditional handover is of a type where a source connection with the source cell remains, a notification to the serving cell.

Abstract: Methods, systems, and devices for wireless communications are described. Devices in a wireless communications system may support different configurations to support intra-symbol multiplexing for communications between the devices using a single carrier waveform. For example, the different configurations may include symbol level cyclic prefixes, device-specific or channel-specific cyclic prefixes, device-specific or channel-specific guard intervals, or a combination thereof to support the intra-symbol multiplexing. That is, the cyclic prefixes or guard intervals may separate different fractions of a symbol, such that individual signals communicated in each of the different fractions do not leak into a subsequent fraction to cause interference. In some implementations, the cyclic prefixes or guard intervals may be enabled for a subset of devices or channels. A configuration for this intra-symbol multiplexing with device-specific or channel-specific cyclic prefixes or guard intervals may be signaled in a control message to the corresponding devices.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), data from one or more beam pairs of a plurality of beams at least partially concurrently; determining, by the UE, one or more signal parameters for the one or more beam pairs; determining, by the UE, one or more joint quasi co-located (QCL) indicators for the one or more beam pairs and one or more non-joint QCL indicators for the one or more beam pairs; and transmitting, by the UE, a measurement report including the one or more joint QCL indicators and the one or more non-joint QCL indicators. In another aspect, a method of wireless communication includes determining a particular beam or beams for transmitting second data based on the measurement report; and transmitting the second data using the particular beam or beams. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A downlink message associated with a feedback process identifier may be received at a first time. An uplink feedback message for the downlink message may be scheduled for a third time. Another downlink message associated with the feedback process identifier may be received after the first time and before the third time. Additionally or alternatively, an uplink grant associated with a feedback process identifier may be received at a first time. An uplink message may be scheduled by the uplink grant for a third time. Another uplink grant associated with the feedback process identifier may be received after the first time and before the third time, and another uplink message may be scheduled by the other uplink grant for a fourth time after the third time.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform respective measurements of one or more demodulation reference signals (DMRSs). Each of the one or more DMRSs may be associated with a repetition of a downlink transmission. Each of the one or more DMRSs may be transmitted on a narrow beam that is located within a wide beam associated with a transmission configuration indication indicated in a grant for the downlink transmission. The UE may transmit an indication of one or more of the respective measurements. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may implement aspects of a single frequency network (SFN), which may support multicast and broadcast transmissions. In some cases, a base station may use directional beamforming techniques to transmit a message to a user equipment (UE) using a first frequency configuration of the SFN. The base station may adjust the first frequency configuration to a second frequency configuration, and may transmit a retransmission of the message to the UE using the second frequency configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration for a set of bandwidth part groups including an intra-group switching delay and an inter-group switching delay, where the intra-group switching delay is smaller than the inter-group switching delay. The UE may communicate with a base station on a first bandwidth part of a first bandwidth part group of the set of bandwidth part groups. The UE may switch to a second bandwidth part of the first bandwidth part group based at least in part on the intra-group switching delay, or the UE may switch to a third bandwidth part of a second bandwidth part group based at least in part on the inter-group switching delay. The UE may communicate with the base station on the second bandwidth part or the third bandwidth part based on switching.
