  • Patent number: 11895679
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

  • Patent number: 11877169
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink transmission from a first cell, where the downlink transmission includes information for performing one or more actions associated with a second cell. The UE may identify a satisfaction of a trigger condition associated with one or more parameters at the UE based on a power level of the UE being less than or equal to a threshold power level, a throughput at the UE being less than or equal to a threshold throughput, or both. The UE may additionally identify at least one bandwidth associated with the second cell based on a previous wireless connection. The UE may compare, the at least one bandwidth associated with the second cell with a threshold bandwidth. The UE may then perform at least one action associated with a procedure based on the comparing.

  • Patent number: 11877335
    Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

  • Publication number: 20230328556
    Abstract: This disclosure provides systems, methods and apparatuses for measurement of cells and determination of a non-standalone (NSA) coverage status using an NSA coverage database. The NSA coverage database may indicate candidate frequencies of New Radio (NR) cells that provide NSA coverage corresponding to a given Long Term Evolution (LTE) serving cell. The NSA coverage database may also indicate whether a system information block 1 (SIB1) has been previously received on a candidate frequency. The user equipment (UE) may perform measurement of candidate frequencies using the NSA coverage database, and may identify cases where a cell not providing NSA coverage has a same candidate frequency as a cell providing NSA coverage using the indication of whether SIB1 has been previously received on a candidate frequency.

  • Publication number: 20230319626
    Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described to enable wake-up signal (WUS) error handling at a user equipment (UE). The UE may detect an error pattern when attempting to receive a WUS from a base station based on a configuration for receiving the WUS. For example, the base station may transmit the configuration for receiving the WUS to a set of UEs including the UE. Based on detecting the error pattern, the UE may perform a mitigation operation based on determining the error pattern, such as waking up multiple cells to receive a transmission indicated by the WUS, transmitting a radio link failure indication to the base station, etc. Additionally or alternatively, the base station may transmit multiple WUSs to the UEs, such as a first WUS according to the configuration and a second WUS according to a reconfiguration.

  • Patent number: 11778497
    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.

  • Publication number: 20230300671
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a receiving device, such as a user equipment (UE), may reduce packet congestion associated with communications between the receiving device and a transmitting device, such as a server, via a radio access network (RAN). The receiving device may measure congestion metrics associated with receiving data packets from the transmitting device via the RAN. The congestion metrics may include RAN congestion metrics and transport or application layer congestion metrics associated with the network connection between the receiving device and the transmitting device. The receiving device may estimate packet congestion at the receiving device according to the measured congestion metrics. The receiving device may modify connection parameters of the network connection based on the estimated packet congestion.
