Abstract: Methods, systems, and devices for wireless communication are described that provide for sharing or isolating network resources between multiple cells in a system. Resources are allocated to multiple cells and multiplexed according to a time division multiplexing (TDM) scheme where a portion of a component carrier is shared between multiple cells. The allocation of resources also includes splitting or sharing a portion of the time resources between two or more cells such that a subframe is allocated as a subframe shared between multiple cells or as a subframe dedicated for use by only a single cell.

Abstract: Certain aspects of the present disclosure provide techniques for managing security keys for enciphering and deciphering packets transmitted in a wireless communications system. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes obtaining an indication of a key area identifier (ID) of a first cell node, wherein the key area ID identifies a set of cell nodes that are associated with a network node that uses a first key for enciphering or deciphering messages and communicating a first set of messages with the first cell node using the first key for enciphering or deciphering the first set of messages.

Abstract: A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in dual connectivity (DC) and with split radio bearers, such that one or more split radio bearers are associated with a first cell group and one or more split radio bearers are associated with a second cell group. In some cases, a cell group failure may occur. Accordingly, the UE may autonomously update one or more radio bearer configurations of the one or more split radio bearers to determine a processing scheme for the cell group failure. Additionally or alternatively, as a result of the cell group failure, an amount of unacknowledged data in a radio link control (RLC) buffer for the second cell group may get stuck such that the network cannot access it. Accordingly, the UE may perform a PDCP data recovery (e.g., user plane handling) to access the unacknowledged data.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices may provide for a time varying allocation of resources which includes a shared pattern of resources. The shared pattern of resources may be generated, determined, or otherwise identified by a base station and transmitted to the user equipment (UE). The shared pattern of resources may include one or more resource blocks (RBs) allocated for uplink transmission such as uplink control information to be transmitted using a physical uplink control channel (PUCCH) or uplink data transmissions using a physical uplink shared channel (PUSCH).

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a base station, associated with a first radio access technology, is shared between one or more operator networks of a second radio access technology; and display an icon corresponding to the second radio access technology based at least in part on a particular operator network, of the one or more operator networks, being a registered operator network of the user equipment and being associated with the second radio access technology. Numerous other aspects are provided.

Abstract: A base station may transmit to a user equipment (UE) one or more indices corresponding to one or more carrier aggregation (CA) band combinations via a UE capability request. The transmitted UE capability requests may include an identifier that corresponds to the UE or the capability procedure between the UE and the base station. Then the UE may respond to the request by including the identifier and an indication of its capability corresponding to the transmitted indices in a UE capability response. Additionally the UE may include an aggregation indicator which signals to the network that the UE's capabilities are to be aggregated with additional indications of UE capability received in other UE capability responses that also include the identifier. Subsequent UE capability responses that include the identifier and an indication that the UE's capabilities may be aggregated will be combined with previously received UE 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.
