Abstract:
A method of wireless communication by a user equipment (UE) includes receiving, from a serving cell, information to assist the UE with interference cancellation of at least one neighbor cell. The method also includes performing interference cancellation based on the information. A method of wireless communication by a network device includes obtaining information to enable interference cancellation of a neighbor cell. The method also includes transmitting the information to assist a user equipment (UE) with interference cancellation of the neighbor cell.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, assistance information that indicates a packet data convergence protocol (PDCP) preference for multiple connectivity communications from a master node and one or more secondary nodes; and receive, from the base station, a communication that indicates a routing of a sequence of PDCP packages across the master node and one or more active secondary nodes. Numerous other aspects are provided.
Abstract:
Methods related to wireless communication systems and uplink (UL) rank adaptation are provided. A user equipment (UE) receives, from a base station (BS), a configuration indicating a resource associated with a plurality of UL reference signal ports. The UE determines, based on at least one of an overheating status, a throughput, or a latency, a quantity of transmission layers for a transmission. The UE transmits, to the BS, an indication of at least one of (1) one or more UL reference signal ports of the plurality of UL reference signal resources associated with the UL reference signal resource based on the quantity of transmission layers, or (2) a number of UL reference signal ports associated with the multi-port UL reference signal resource based on the quantity of transmission layers.
Abstract:
Certain aspects of the present disclosure provide techniques for slot aggregation configuration with user equipment (UE) assistance information. A method that may be performed by a UE may include transmitting, to a base station (BS), assistance information indicating a preferred repetition factor. The method generally includes receiving an indication from the BS of a repetition factor. The BS can determine the repetition factor for the UE based, at least in part, on the assistance information and indicate the determined repetition factor to the UE.
Abstract:
This disclosure provides systems, methods and apparatuses for adding and releasing secondary cells in a multi-cell connectivity configuration. In one aspect, a user equipment (UE) may transmit UE assistance information to a base station (BS) operating as a master cell in a multi-cell connectivity configuration. The UE assistance information may indicate a process that the BS is to use to add a secondary cell to the multi-cell connectivity configuration, may indicate a time gap for adding a secondary cell after another secondary cell is released from the multi-cell connectivity configuration, as well as other multi-cell connectivity configuration information. The BS may receive the UE assistance information and may add a secondary cell to the multi-cell connectivity configuration based at least in part on the indicated process and time gap.
Abstract:
This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.
Abstract:
Certain aspects of the present disclosure provide techniques for sharing uplinks in a multiple radio access technology environment. Such techniques may improve transmission and processing of acknowledgment data from a user equipment in the multiple radio access technology environment.
Abstract:
In one instance, a user equipment (UE) compares an expected duration of a tune away procedure with a first time remaining before a discard timer expires, a second time remaining before a downlink reordering timer (DL reordering timer) for adjusting an order of data at a buffer expires, a third time remaining before a retransmission timer expires and/or a fourth time remaining before an expected time to receive acknowledgement feedback ends. The UE also determines whether to adjust a tune away procedure based on the comparing. The tune away procedure may include the UE tuning away from a first radio access technology (RAT) to a second RAT during a communication procedure at the first RAT.
Abstract:
A method and system for wireless communications at a user equipment utilizes buffer status reporting during call setup, including voice-over IP (VoIP) call setup. The UE determines it has no data in a data buffer to send during a call setup. The UE then sends a first scheduling request and a non-zero buffer status for the data buffer during the call setup before a data inactivity timer expires.
Abstract:
A user equipment (UE) improves handover throughput by reducing communication interruptions during a handover transition. To reduce the communication interruptions, the UE determines whether to perform a synchronization channel decoding procedure for a synchronized handover to a second radio access technology (RAT) after receiving a handover command from one or more serving cells of a first RAT. The determination includes determining whether a communication condition is satisfied and performing the synchronized handover based on whether the communication condition is satisfied. The synchronization channel decoding procedure includes frequency correction channel (FCCH) tone detection and/or synchronization channel (SCH) decoding after the UE transitions to a target cell of the second RAT.
