Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the UE, a PUR configuration release trigger for the PUR configuration. The method further includes receiving, by the UE, a PUR configuration release message configured to release the PUR configuration. In another aspect, a method of wireless communication includes transmitting, by a network entity, a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the network entity, a PUR configuration release trigger for the PUR configuration. The method further includes transmitting, by the network entity, a PUR configuration release message configured to release the PUR configuration. Other aspects are described and claimed.

Abstract: Methods, systems, and devices for wireless communications are described to differentiate random access response types, such that a user equipment (UE) may identify a random access response for the UE. A UE may transmit a random access message that may be associated with a first type of random access response. The base station may be configured to communicate different types of random access responses, and may configure a random access response and an associated downlink control signal to correspond to the first type of random access response. The base station may transmit the downlink control signal to the UE by configuring different demodulation reference signals, different group identifiers, different search spaces or control resource sets, or different downlink control information. The UE may determine that the random access response is of the first type and may receive the random access response based on the decoded downlink control signal.

Abstract: An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

Abstract: Wireless communications systems as described herein may be configured to provide user equipment (UE) assisted information for caching data at a network node external to a core network (CN). In some cases, the UE may provide an acceleration indicator (AI) that a base station may receive and identify as caching information. The base station, upon identifying that the AI is present in an uplink packet, may transmit the packet to a gateway having a local cache. If the uplink packet does not have an AI, the base station may route the uplink packet according to an address (e.g., a uniform resource locator (URL)) contained in the packet.

Abstract: Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.

Abstract: Enhancement of long term evolution (LTE) time division duplex (TDD) carrier aggregation for half duplex user equipments (UEs) is discussed. In one aspect of enhanced TDD carrier aggregation, the UE monitoring for a control signal indicating subframe configuration for each TDD cell of an aggregated set of TDD cells in the same band. The UE may determine the downlink subframes and receive downlink transmissions on such subframes based on the control signal. In another aspect, the UE compares the number of scheduled uplink and downlink subframes between the TDD cells in the same band to determine the downlink error-control messaging timing for each cell.

Abstract: Embodiments methods implemented with a server or a processor of a mobile communication device (e.g., a multi-standby communication device) reduce the redundancy information needed to achieve adequate reception service on a first radio access technology (RAT) sharing an RF resource with a second RAT. The device processor may implement at least one tune-away management strategy that mitigates the amount of data for the first RAT that is lost during the tune-away event. Thus, by implementing the one or more tune-away management strategies, the device processor may ensure that less redundancy information overhead is needed to correct or replace lost or partially received data, improving latency, channel usage, and the first RAT's overall reception performance. In some embodiments, a server may implement one or more strategies for including redundancy information into data that is sent to a first RAT to mitigate the negative effects of tune aways on the first RAT.
