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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a wireless communication device, a measurement time indication for measuring at least one signal associated with at least one inter-frequency neighbor cell. The UE may receive the at least one signal associated with the at least one inter-frequency neighbor cell based at least in part on the measurement time indication. Numerous other aspects are provided.

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 receive a first information element (IE) and a second IE, wherein the first IE indicates whether all UEs that do not support cell-specific reference signal (CRS) muting are barred from a carrier and the second IE indicates whether all UEs that support CRS muting are barred from the carrier; and selectively access the carrier based at least in part on at least one of the first IE or the second IE. In some aspects, a UE may determine whether the UE supports cell-specific reference signal (CRS) muting; and transmit, to a base station, a capability report that indicates whether the UE supports CRS muting. Numerous other aspects are provided.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving, at the UE, a random access response including a first signal via a first physical channel and a second signal via a second physical channel from a base station (BS), generating a connection request based on the random access response, estimating a carrier to interference plus noise ratio (CINR) of a random-access channel based on at least one the first signal or the second signal, and sending a message including the CINR and the connection request to the BS in response to the random access response.

Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.

Abstract: Techniques described herein use a wakeup signal to indicate to a user equipment (UE) whether an upcoming control channel signal resource includes information relevant to the UE. In this way, the UE can wake up to perform complex control channel signal processing only when the control channel includes signals relevant to the UE, thereby conserving battery power and resources of the UE. Such techniques are particularly suited to MTC UEs, NB-IoT UEs, and/or the like, which may communicate with a network only occasionally, and which may be located in remote locations where changing or recharging a battery is difficult.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus retrieves a particular number corresponding to a UE. To retrieve the particular number, the apparatus may receive the particular number through a channel request from the UE. Alternately, the apparatus may assign the particular number to the UE in order to retrieve the particular number. The apparatus determines a resource block within a coverage class based on the particular number. To determine the resource block, the apparatus maps the particular number to a resource block number within the coverage class using a hash function. The resource block number identifies the resource block. The apparatus transmits a device-specific control message to the UE using the determined resource block.
