Abstract: This disclosure describes methods, systems, and devices for broadcasting a Physical Downlink Control Channel-based (PDCCH-based) wake-up signal. In one example, a method involves receiving, by one or more user equipment (UEs), a configuration for monitoring a wake up signal (WUS). The method further includes monitoring, by the one or more UEs and based on the configuration, a physical downlink control channel (PDCCH) for downlink control information (DCI) associated with the WUS. The method also includes receiving, by the one or more UEs, the WUS in response to detecting the DCI.

Abstract: Systems, Methods, Devices, and Apparatuses for power saving are provided. In at least one embodiment, a device may be configured for discontinuous reception (DRX) mode and further receive signaling indicating whether or not to wake and/or may receiving signaling indicating whether or not to go-to-sleep. The signaling may be implemented as group-specific signaling.

Abstract: A number of embodiments can describe the operation of a UE in an unlicensed spectrum. Operating a UE in an unlicensed spectrum can include processing a PDCCH transmission provided by an eNodeB to identify a resource for a transmission of the SR message and based on the resource identified in the PDCCH, generating a PUCCH transmission comprising the SR message for the eNodeB.

Abstract: A telecommunication network may operate to enable a wake up signals (WUSs) within the telecommunication network. A mobility management entity (MME) may estimate a coverage enhancement (CE) level of a user equipment (UE), determine, based on the CE level, a number of repetitions for a wake up signal (WUS) for the UE, and cause a WUS for UE to be transmitted to a radio access network (RAN) node corresponding to the UE. The RAN node may inform the MME that the RAN node has disabled the WUS feature, and may cause system information to be broadcast to UEs in IDLE mode, indicating that the WUS feature of the RAN node has been disabled. A UE may determine a paging occasion (PO) determine a maximum WUS duration, minimum offset, and start location of the WUS.

Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, the CRS can be transmitted at frequency locations based on CRS muting configuration parameters.

Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

Abstract: Described herein are methods and apparatus for implementing discontinuous reception (DRX) states in user equipments (UE) in order to conserve battery power. In particular, methods and apparatus for signaling the UE to transition between different DRX states using L1 signaling such as over the physical downlink control channel (PDCCH) are described.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to encode a Non-scheduled Physical Uplink Control Channel (N-PUCCH) in an Uplink (UL) burst transmission, and to encode a Physical Uplink Shared Channel (PUSCH) in the UL burst transmission. The second circuitry may be operable to initiate the UL burst transmission subject to a Listen-Before-Talk (LBT) protocol on a channel of the wireless network. The UL burst transmission may be initiated without a UL grant received from the eNB.
