Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE or a component thereof configured to receive, from a base station, SPS configuration information for broadcast and/or multicast indicating a set of resources configured for feedback, with each transmit (TX) beam of a set of TX beams corresponding to a respective subset of the set of resources. The apparatus may be further configured to receive SPS signaling from the base station via one or more TX beams of the set of TX beams over each of a set of SPS occasions. The apparatus may be further configured to transmit feedback to the base station on one or more subsets of the set of resources respectively corresponding to the one or more TX beams based on the SPS signaling, the feedback indicating one of acknowledgement (ACK) or non-acknowledgement (NACK).

Abstract: Apparatus, methods, and computer-readable media for facilitating using of pre-configured UL resources to transmit grant-free data or reference signals are disclosed herein. An example method for wireless communication by a UE includes transmitting, to a base station, a capability of the UE to transmit data in a first message of a random access procedure. The example method also includes receiving pre-configured UL resources from the base station. The example method also includes transmitting data in the first message of the random access procedure using the pre-configured UL resources.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission type for a physical downlink shared channel, wherein the transmission type is a multicast transmission type or a unicast transmission type. The UE may determine, based at least in part on the transmission type for the physical downlink shared channel, a transmission configuration indicator state, of a plurality of possible transmission configuration indicator states, that corresponds to a quasi-co-location assumption, of a plurality of possible quasi-co-location assumptions, for the physical downlink shared channel. The UE may decode the physical downlink shared channel based at least in part on the transmission configuration indicator state. 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 a broadcast or a multicast (broadcast/multicast) scheduling configuration for a physical downlink control channel (PDCCH), the broadcast/multicast scheduling configuration identifying, for receiving broadcast/multicast communications, at least one of: a plurality of radio network temporary identifiers that are respectively associated with a plurality of beams, or one or more bandwidth parts. The UE may receive a broadcast/multicast communication associated with a broadcast/multicast control channel or a broadcast/multicast traffic channel via a physical downlink shared channel in accordance with the broadcast/multicast scheduling configuration for the PDCCH. Numerous other aspects are provided.

Abstract: A configuration to allow a UE to receive a BWP configuration that supports RC NR. The UE sends information to a network indicating a UE capability of the UE. The UE receives, based on the UE capability, information indicating a BWP associated with a first BWP, the second BWP having a frequency range equal to or less than the first BWP. The UE receives at least one of control information or data based on the indicated first BWP and the second BWP.

Abstract: Certain aspects of the present disclosure provide techniques for capability information for sounding reference signal (SRS) improvements. An exemplary method generally includes determining a capability of the UE related to additional sounding reference signal (SRS) transmissions in a normal uplink (UL) subframe; transmitting, to a base station (BS), capability information indicating the determined capability of the UE; receiving SRS configuration information, wherein the SRS configuration information is based, at least in part, on the capability information; and transmitting at least one SRS in accordance with the SRS configuration information.

Abstract: A base station may calculate a scheduling value based on at least one of a number of groups associated with a set of UEs operating on a cell provided by the base station a radio frame number, or a subframe number. The base station may send, based on the calculated scheduling value, at least one NRS in at least one PO on a narrowband control channel. A UE may receive, from the base station providing the cell, information associated with at least one PO for the UE. The UE may determine, based on the received information, scheduling information associated with at least one NRS in the at least one PO. The UE may detect the at least one NRS in the at least one PO on a narrowband control channel when the determined scheduling information indicates the at least one NRS is in the at least one PO.

Abstract: Various aspects described herein relate to techniques for frequency hopping for a wideband allocation in wireless communications. A wideband allocation of resources for transmitting uplink wireless communications can be determined, as well as a frequency hopping offset related to one or more narrowbands for transmitting uplink wireless communications. In addition, it can be determined whether to apply the frequency hopping offset to the wideband allocation in communicating data. The data can be communicated over resources related to the wideband allocation with the frequency hopping offset applied communicating, based on determining to apply the frequency hopping offset.
