Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a set of time instances to monitor for paging, wherein the set of time instances are identified based at least in part on a first discontinuous reception (DRX) cycle parameter set, identify a subset of time instances, of the set of time instances, for which a narrowband reference signal is to be monitored irrespective of whether paging is present on the subset of time instances, wherein the subset of time instances is identified based at least on a second DRX cycle parameter set; and communicate based at least on the set of time instances and the subset of time instances. Numerous other aspects are provided.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

Abstract: Methods, systems, and devices for increasing physical random access channel (PRACH) capacity using orthogonal cover codes (OCCs) in wireless communications systems are described. A base station may transmit a PRACH configuration that indicates PRACH resources for system access, for example, in a system information block (SIB). A user equipment (UE) may receive the PRACH configuration, and may identify PRACH resources that support OCCs for system access. For example, PRACH configurations with small time domain spacing between PRACH resources may support OCCs. The UE may determine whether to transmit random access (RACH) preamble messages using OCCs in the PRACH resources, and may transmit a RACH preamble message to the base station based on the determination. In some cases, the base station may additionally indicate PRACH resources not configured for OCCs, and the UE may determine which set of resources to transmit in based on one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally includes receiving, from the network, a message comprising sounding reference signal (SRS) configuration information, wherein the SRS configuration information comprises configuration information for a first SRS resource set and configuration information for a second SRS resource set and transmitting at least one SRS according to the received SRS configuration information.

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, a method for a user equipment (UE) is provided. In some examples, the UE determines a signal quality for communicating with a node. The UE determines a coverage level based on the signal quality, wherein the coverage level indicates resources to be used for communicating with the node. The UE determines a maximum repetition level and a repetition value, based on the coverage level, for communicating with the node. The UE generates a multibit repetition range identifier that indicates the repetition value based on the maximum repetition level. The UE transmits the multibit repetition range identifier.

Abstract: Some techniques and apparatuses described herein provide synchronization signal numerology, coverage extension/repetition schemes, and synchronization signal burst set periodicities for 5G IoT user equipment (UEs). For example, some techniques and apparatuses described herein provide a sequence of slots and/or particular symbols within a slot for transmission of a synchronization signal and/or a broadcast channel. Furthermore, some techniques and apparatuses described herein define minimum bandwidths of IoT UEs in relation to non-IoT UEs, and define synchronization signal burst set periodicities that may be different for IoT UEs than for non-IoT UEs.
