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: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for communicating data between a user-equipment and network entity. For example, certain aspects of the present disclosure provide a method for wireless communication. The method generally includes receiving a message comprising a data packet from a user equipment (UE) during a communication session, and detecting whether the data packet is the last data packet for transmission or reception by the UE during the communication session. In certain aspects, the method also includes determining whether to process or discard the data packet based on the detection and whether a backoff timer is to be sent to the UE, and processing or discarding the data packet based on the determination.

Abstract: Techniques are described using network slice information to negotiate and select network services by determining a set of desired required network provided functionalities; identifying a set of network slices providing one or more of the functionalities in the set of required functionalities; and communicating, to a network, a slice identifier for each slice in the set of the identified network slices.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing broadcast information on supported and non-supported slices using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communication by a user equipment (UE) may generally include receiving signaling of at least one of: a first list of network slices indicated as available in a first cell or a second list of network slices indicated as unavailable in the first cell, and performing at least one of cell reselection or cell selection taking into account the network slices listed in the at least one of the first list or the second list.

Abstract: Extended DRX (e-DRX) operation using hyper frame extension signaling are described. The hyper frame extension signaling may extend the system frame number (SFN) range while maintaining backward compatibility for legacy devices not configured to use the extended SFN range. The hyper-SFN extension signaling may include an index to a hyper-SFN transmitted as part of system information different than that used for transmission of the SFN. UEs configured to use the hyper-SFN may effectively use a longer or extended SFN range that includes the legacy SFN range and the hyper-SFN range. The hyper-SFN extension may be used in an extended idle DRX (eI-DRX) mode which may coexist with existing I-DRX mode on the same paging resources. Additionally or alternatively, paging may be differentiated for eI-DRX mode UEs using separate paging occasions or a new paging radio network temporary identifier (RNTI).

Abstract: Aspects described herein relate to communicating using multicast in a wireless network. A connection with an access point can be established using a cellular radio access technology. An internet protocol request for multicast communications can be transmitted to the access point over the connection. Multicast data can be received from the access point over resources corresponding to over-the-air multicast communications based on the internet protocol request.

Abstract: Systems, methods, and devices for priority based management of the connections between a device and a network are described herein. In some aspects, a device may include multiple applications with different access priorities. As a result of a mobility event, such as change in location or resuming operation after an idle period, the device may be configured to transmit a signal indicating its status. The signal may include an access priority value. Various methods and systems for determining an access priority value for devices configured to support one or more access priorities are described.
