Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: In some aspects, the SIB1 message is transmitted in a subframe 0 and a subframe 5 of alternating radio frames of the non-anchor carrier. In some aspects, the SIB1 message is transmitted in a subframe 0 of alternating radio frames of the anchor carrier. In some aspects, the frequency domain location parameter is associated with a physical resource block offset relative to a center frequency, and the anchor carrier is in a first frequency range greater than the center frequency by the physical resource block offset and the non-anchor carrier is in a second frequency range less than the center frequency by the physical resource block offset, or the non-anchor carrier is in the first frequency range greater than the center frequency by the physical resource block offset and the anchor carrier is in the second frequency.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information (DCI) message to one or more user equipments (UEs) scheduling a multicast data message in a multicast downlink shared channel, the DCI message indicating a feedback process identifier (ID) for the multicast data message. The base station may transmit an additional DCI message to a UE scheduling a retransmission of the multicast data message in a unicast downlink shared channel and indicating a feedback process ID for the retransmission of the multicast data message. The feedback process ID for the retransmission may be the same as, or different from, the initial transmission of the multicast data message. The UE may transmit feedback for the multicast data message based on receiving the initial transmission of the multicast data or the retransmission of the multicast data and the feedback process IDs.

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: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive broadcast information from a base station indicating a numerology or a reference signal (RS) pattern to be used in broadcast or multicast transmissions (e.g., a physical multicast channel (PMCH)). The UE may identify a modulation and coding scheme (MCS) associated with the broadcast or multicast transmission and may determine a transport block size (TBS) based on the MCS and at least one of the numerology or the RS pattern. For instance, a UE may determine TBS for numerologies associated with a single symbol that spans multiple subframes differently from that of other numerologies. Additionally or alternatively, a UE may determine TBS for sparse RS patterns differently from that of other RS patterns. The UE may then perform communication with the base station via the broadcast or multicast transmissions in accordance with the TBS.
