Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to adjusting how certain types of devices wake up and/or stay awake for broadcast service. A method for wireless communications is provided that may be performed by a user equipment (UE). The method includes receiving a power savings configuration indicating sleep periods during which the UE is scheduled to be unreachable. The method includes determining at least one time, during at least a portion of one of the indicated sleep periods, for the UE to be awake in order to at least one of: receive or discover Multimedia Broadcast Multicast Services (MBMS) user services.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: Communication using a radio access network (RAN) including a primary cell for license spectrum access and a secondary cell for unlicensed spectrum access may be improved to provide optimal performance while considering characteristics of the primary cell and the secondary cell. The apparatus may be a core network entity. The core network entity is connected to a RAN including a primary cell utilizing a licensed spectrum and a secondary cell utilizing an unlicensed spectrum. The core network entity determines an authorization for data traffic to be offloaded to the secondary cell based on data traffic characteristics. The core network transmits an indication of the authorization to the RAN.

An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.

Abstract: Techniques are provided for decoupling uplink and downlink operations. According to certain aspects, a wireless node (e.g., a low power node) may receive, from a base station of a first cell, signaling indicating a random access channel (RACH) configuration for a wireless device. The wireless node may then detect the wireless node performing a RACH detection (based on the RACH configuration) and report the RACH detection and desired UL configuration to the base station of the first cell. The base station of the first cell may then select the wireless node for serving the wireless device for UL operations (e.g., based on the reported RACH detection-and similar reports from other wireless nodes detecting the same RACH procedure).
