Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Abstract: The present disclosure relates to transmitting and receiving a group wake-up signal (WUS) in conjunction with an ungrouped WUS. A base station may group one or more UEs in a UE group, while other UEs may not be assigned to a UE group. The configuration of WUS resources and WUS sequences for grouped UEs and other UEs is a challenge. The base station may transmit, to one or more UEs in the UE group, a resource allocation of a group WUS resource within a set of WUS resources associated with a paging occasion that is assigned to the one or more UEs in the UE group. A UE, after receiving the resource allocation, may determine a location of the group WUS resource within the set of WUS resources. The UE may monitor for a group WUS at the determined location in the resource allocation of the group WUS resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a downlink communication is to be transmitted to the UE with a configurable gap. The UE may determine the configurable gap. The UE may receive the downlink communication based at least in part on the configurable gap. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and an enhanced machine-type communications (eMTC) user equipment (UE) may receive, an indicator indicating use of a control region of a carrier for a downlink transmission. The BS may transmit and the eMTC UE may receive, based at least in part on the indicator, the downlink transmission during the control region of the carrier. Numerous other aspects are provided.

Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

Abstract: Some techniques and apparatuses described herein allocate and/or transmit a narrower bandwidth value for LTE MTC UEs, such as UEs that operate in a small bandwidth mode using LTE procedures, and allocate and/or transmit a wider bandwidth value for 5G MTC UEs, such as UEs that can perform hopping and/or be allocated resources outside of a legacy bandwidth. For example, the wider bandwidth value may be associated with a non-LTE carrier (e.g., a 5G carrier in a 5G bandwidth) with the same center frequency as an LTE carrier associated with the narrower bandwidth value. Some techniques and apparatuses described herein provide for initial access, signaling, paging, random access, unicast communications, frequency hopping, cell-specific reference signaling, narrowband alignment, and/or other coexistence considerations for LTE MTC UEs operating on an LTE carrier and 5G MTC UEs operating on a non-LTE carrier with a bandwidth that includes the LTE carrier.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method generally includes receiving a configuration message for narrowband internet of things (NB-IoT) communication, the configuration message indicating one or more parameters for uplink transmission using a modulation and coding scheme (MCS) associated with a modulation order of at least four, generating the uplink transmission, and sending the uplink transmission in accordance with the one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration and processing enhancements. A method generally includes receiving, from the network, signaling indicating a sounding reference signal (SRS) configuration allocating a plurality of symbols for SRS transmissions within an uplink (UL) subframe, detecting a collision between at least one of the allocated SRS symbols and another type of UL transmission, and taking one or more actions regarding the SRS transmissions, based on the detection of the collision.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a set of measurements related to a unicast service channel based at least in part on one or more reference signals associated with the unicast service channel and a set of measurements related to a multicast/broadcast service (MBS) channel based at least in part on one or more reference signals associated with the MBS channel. The UE may apply one or more communication parameters to ensure continuity for an MBS service. For example, in some aspects, the one or more communication parameters are based at least in part on the set of measurements related to the unicast service channel and the set of measurements related to the MBS channel. Numerous other aspects are provided.
