Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provided techniques that for wireless communications by a user equipment (UE). An exemplary method, performed by a UE, generally includes obtaining a first system information message from a wireless network configured to utilize Multimedia Broadcast multicast service Single Frequency Network (MBSFN) subframes and non-MBSFN subframes, determining, based on the first system information message, a first set of valid subframes and a first set of non-MBSFN subframes, obtaining a second system information message from the wireless network based on the first set of valid subframes and the first set of non-MBSFN subframes, and accessing the wireless network based on the first system information message and the second system information message.

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.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

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: Certain aspects of the present disclosure relate generally to communication systems, and more particularly, to enhanced reporting by user equipment (UE). An example method generally includes receiving an information request from a network node and in response, sending a message to the network node, wherein the message comprises information that allows the network node to determine a starting coverage enhancement (CE) level of the UE.
