Abstract: Aspects of the present disclosure provide a scalable SIB bitmap structure. As described herein, a UE may generate and transmit, to an access network, a dual-layer system information block (SIB) request, wherein a first layer indicates a SIB category and a second layer indicates one or more groups within the SIB category. A base station in an access network may receive, from a UE, the dual-layer SIB request. The scalable, efficient bitmap structure may be shared by the UE and access network, thereby enabling SIB-on-Demand requests by the UE and responses to SIB-on-Demand requests by the access network.

Abstract: Methods, systems, and devices for wireless communication are described. A per-frequency indication providing deployment options for communication with a core network may be used for enhanced cell selection by a user equipment (UE). For example, system information transmitted by a base station may provide information elements that indicate, per radio frequency (or per radio frequency (RF) spectrum band)), deployment options associated with nearby cells. In such cases, the UE may determine whether to access the radio frequencies or RF bands of these cells based on the capabilities of the UE. In some cases, the UE may further determine whether the nearby cells are available based on the availability of a service through those cells. Accordingly, the UE may select one of the radio frequencies or bands corresponding to the cell having a network connectivity configuration that supports the UE's capabilities.

Abstract: A system and method for mobility tracking of user equipment in a network includes a user equipment. The user equipment includes an antenna for receiving and sending signals to a plurality of network nodes in a network and a processor coupled to the antenna. The processor is configured to broadcast, using the antenna, a pilot signal to advertise the user equipment, receive, using the antenna, a pilot response from a first network node acting as a serving node for the user equipment, and communicate with the network through the serving node. The pilot signal includes a reference sequence for the network nodes to track followed by a payload including information about an identity of the user equipment. In some embodiments, the reference sequence varies based on a state of the user equipment. In some embodiments, the reference sequence is randomly selected.

Abstract: Logical channel prioritization and mapping to different numerologies is disclosed for 5G networks having multiple network slices operable for communication via logical channels associated with different numerologies. For user equipments (UEs) configured to handle multiple numerologies, different rules for mapping logical channels associated with different numerologies may be defined for data and non-data channels. Thus, when new data arrives at a UE for communication via a logical channel associated with a different numerology, the UE checks whether the mapping rules would allow multiplexing of the new numerology data onto an existing data channel. If no data channel has already been allocated or if an allocated data channel may not include data from the new numerology, then a mapping is followed for specifically requesting resources for communication of the new numerology data. The new mapping may trigger scheduling request or random access procedures specifically associated with the new numerology.

Abstract: Systems and methods for enabling and providing uplink based mobility procedures are disclosed. Embodiments provide uplink based mobility procedures in which one or more physical channel typically used to facilitate uplink based mobility is not utilized. For example, an uplink based mobility process of embodiments utilizes a UL-based mobility specific ID and/or synchronization signals to provide information for decoding signals avoiding the use of physical cell identifier channel (PCICH). Embodiments of an uplink based mobility process utilize a physical channel, such as a physical slot format indication channel (PSFICH) or a physical downlink control channel (PDCCH), to provide uplink mobility signal acknowledgements and paging indications avoiding the use of a physical keep alive channel (PKACH).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.
