Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may enable selection of a modulation order (Qm) parameter, a transport block size (TBS) parameter, a quantity of subframes in a transport block (NSF) parameter, and/or the like. For example, based at least in part on receiving a downlink control information or another factor, a user equipment may select, for example, a table of Qm, TBS, and NSF values and may select a particular set of a Qm value, a TBS value, and an NSF value from the table. In this way, the UE may use a higher order modulation and coding scheme in, for example, a narrowband Internet of Things deployment.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

Abstract: Certain aspects of the present disclosure provide techniques for neighbor cell measurements for narrowband communications. An example method generally includes detecting a trigger to take neighbor cell measurements while a user equipment is in a radio resource control (RRC) connected state with a serving cell, based at least in part on a threshold applied to a channel condition metric measured for the serving cell and one or more additional conditions. The method also includes taking neighbor cell measurements in response to detecting the trigger.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first transmission including encoded bits of a data packet and a second transmission including some or all of the encoded bits of the data packet. The first transmission associated with a first limited buffer rate matching (LBRM) configuration and the second transmission may be associated with a second LBRM configuration. The UE may process the first transmission and the second transmission based on the first LBRM associated with the first transmission being different than the second LBRM associated with the second transmission.

Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.

Abstract: Methods, systems, and devices for multicast wireless communications are described. A base station may configure a user equipment (UE) for providing feedback for multicast transmissions from the base station while the UE is in an inactive or idle mode. Based on a configuration sent to the UE from the base station, the UE may determine resources or a timing advance (TA) to use for transmission of a feedback message for multicast communications. A base station may configure a UE with multiple TA commands, each corresponding to a TA value and a set of channel metrics associated with group of cells including a serving cell of the UE. Based on measure channel metrics at the UE, the UE may determine a TA to use for multicast feedback. TA values may be determined using neural network modeling.
