Abstract:
A user equipment (UE) may utilize multiple radio link control (RLC) entities to duplicate packet data convergence protocol (PDCP) packets for improved reception. The UE may receive a configuration for dual connectivity with a master cell group and with a secondary cell group, wherein the configuration identifies a plurality of configured RLC entities, each RLC entity being associated with one of the master cell group or the secondary cell group. The UE may receive, at the UE, an indication of an activation status for each of at least a first subset of the configured RLC entities from one cell group of the master cell group or the secondary cell group. The UE may set the activation status of each of the first subset of the configured RLC entities that are associated with the one cell group from which the indication is received based on the indication.
Abstract:
Apparatus, methods and computer-readable media for broadcast of multiple physical cell identity ranges are disclosed herein. A user equipment (UE) can receive system information (SI) containing physical cell identities (PCIs) associated with a first cell type or a second cell type, in which the first cell type is accessible to a first set of UEs and the second cell type is accessible to a second set of UEs and a second set of PCIs containing PCIs corresponding to a set of cells of the second cell type. The UE can also monitor for cells with a PCI in the first set of PCIs or the second set of PCIs. A base station may generate the SI indicating the first set of PCIs and the second set of PCIs. Additionally, the base station can communicate the SI to one or more UEs.
Abstract:
A wireless communication system is provided allowing a base station to indicate RTT compensation for UEs to adjust their local time clocks to correct propagation delay timing errors and synchronize with the global clock of a base station. A base station sends a downlink transmission including timing information to a UE and receives an uplink transmission from the UE after the downlink transmission. The base station determines a RTT compensation associated with the timing information based on a RTT between the downlink transmission and the uplink transmission. The base station then transmits the RTT compensation to the UE. UEs are thus allowed to synchronize at a high precision with the time clock of the base station. UEs may be configured with different resolutions or granularities in timing correction so that certain UEs can achieve high precision timing correction while other UEs can adjust their time clocks with less precision.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a reserved resource allocation, wherein the reserved resource allocation is associated with a reserved resource; receive information identifying another resource allocation, wherein the other resource allocation overlaps with the reserved resource allocation at an overlapped portion; and selectively perform a communication using the overlapped portion for the reserved resource allocation or the other resource allocation based at least in part on at least one of: respective traffic types of the reserved resource allocation and the other resource allocation, or respective priority levels associated with the reserved resource allocation and the other resource allocation. Numerous other aspects are provided.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may transmit a supported configuration of the UE for at least one of SRS transmission or CSI-RS reception for communication with a plurality of TRPs. The apparatus may receive, in response to transmitting the supported configuration, configuration information for at least one of the SRS transmission or the CSI-RS reception, wherein the configuration information is generated based on the supported configuration. The apparatus may communicate, with at least a subset of the plurality of TRPs, using at least one of the SRS transmission or the CSI-RS reception on resource elements assigned based on the configuration information. A base station connected to the TRPs may use the SRS/CSI-RS for cluster management and scheduling or to estimate downlink channels to determine precoding for downlink transmissions.
Abstract:
Various aspects described herein relate to techniques for communications in a coordinated multi-point (CoMP) wireless communications system. In an aspect, a method of wireless communications may include receiving a request to form a CoMP cluster set of transmit/receive points (TRPs) for a user equipment (UE), determine the CoMP cluster set of TRPs for the UE based on at least a delay budget and a reliability requirement, and one or more of configuration information and measurements, and coordinate communications for the UE using the CoMP cluster set. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may include a UE. The apparatus may send a first subscription request message to a provisioning entity. In certain aspects, the first subscription request message may request one or more subscriptions. In certain other aspects, each subscription may include at least one or more credentials. The apparatus may receive the one or more subscriptions from the provisioning entity when the one or more subscriptions are available. The apparatus may send a second subscription request message after a polling interval to the provisioning entity when the one or more subscriptions are not received. In certain aspects, the second subscription request message may be sent when the one or more subscriptions are not received in response to the first subscription request.
Abstract:
A non-MNO PSP network maintains a table that maps external subscriber identifiers of UEs to intermediate subscriber identifiers of the UEs on an interface between the non-MNO PSP network and NHN(s). The non-MNO PSP network obtains an SCEF-related message including either an external subscriber identifier or an intermediate subscriber identifier for the UE. Using the table, the non-MNO PSP network forwards the SCEF-message to a serving NHN or to an external application. In another embodiment, an NHN maintains a table that maps internal identifiers of UEs within the NHN to intermediate subscriber identifiers that identify the UEs on an interface between the NHN and non-MNO PSP(s). The NHN obtains an SCEF-related message that includes an intermediate subscriber identifier or an internal identifier for the UE. Using the table, the NHN either processes the SCEF-related message within the NHN, or forwards the SCEF-related message to a non-MNO PSP outside the NHN.
Abstract:
The disclosure describes methods and apparatuses for handover-related measurements and events for power adaptation. The disclosure provides for management of an eNodeB for improving reliability of incoming handovers to a cell provided by the eNodeB. At least one handover failure event for an incoming handover to a cell provided by the target eNodeB is detected. The eNodeB or central entity determines that the cell is providing an undesired coverage area based on the at least one handover failure event. In response to determining that the cell is providing an undesired coverage area, the transmit power for the cell may be adjusted to alter the undesired coverage area. A performance measurement based on the at least one handover failure event may be used to evaluate the undesired coverage area. The incoming handover failure events may include incoming too-early handovers, incoming too-late handovers, incoming wrong cell handovers, and incomplete incoming handovers.
