Abstract:
A user equipment (UE) and a method of using the UE are provided for fulfilling a network's intent to increase or decrease the serving grant for the UE in spite of a deadlock condition that may otherwise prevent fulfillment of the network's intent. That is, upon determining the network's intent, the UE may alter its serving grant according the intent by altering the number of packets for transmission in a TTI.
Abstract:
Apparatus and methods are described herein for maintaining both a circuit-switched voice call and a packet-switched data session alive during a multi-RAB call. A determination is made as to whether a user equipment (UE) is in a power-limited situation. If it is determined that the UE is in a power-limited situation, one or more operating conditions are adjusted to maintain the multi-RAB call while in the power-limited situation.
Abstract:
A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.
Abstract:
The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.
Abstract:
This disclosure provides systems, methods, and devices for wireless communication that support enhanced power saving mode (PSM) for an active time duration of a PSM with extended discontinuous reception (eDRX) configuration in a wireless communication system. In one aspect, a user equipment (UE) is configured to enter a deep sleep mode during inactive times of a PSM, and to operate in eDRX mode during the active times of the PSM. Operating in eDRX mode during the active times includes dividing each of the active time durations into at least one eDRX idle period and at least one eDRX paging period. The UE determines whether a set of criteria for implementing a variant of the PSM is met, and when the set of criteria is met, the UE implements the variant of the PSM, which includes powering down the UE to a deep sleep mode at least during eDRX idle periods.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.
Abstract:
Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes: performing connection reestablishment in response to a triggering condition, the connection reestablishment comprising: suspending operation of at least one data radio bearer (DRB) for carrying user data, transmitting a connection reestablishment request to a base station (BS), receiving from the BS a connection reestablishment message, and transmitting a connection reestablishment complete message to the BS; and transmitting at least a portion of the user data over non-access stratum (NAS) signaling, before the operation of the at least one suspended DRB is resumed.
Abstract:
Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a data transmission to a receiver. In some examples, the data transmission may be a radio link control (RLC) protocol data unit (PDU) transmission. The UE may store the data transmission in a retransmission buffer, and transmit a feedback request to the receiver in a subsequent data transmission based on a system memory utilization threshold for the retransmission buffer being satisfied due to storage of the data transmission.
Abstract:
Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to power savings based on distributed enhanced machine type communication (eMTC) functions, for example, between an applications processor and a modem of an eMTC device. An example method generally includes entering a power saving mode (PSM), wherein entering the PSM includes performing a first power collapse of an applications processor of the wireless node and a modem of the wireless node into a low power state; exiting the PSM at expiry of a wake-up timer, wherein exiting the PSM includes waking up the applications processor and the modem from the low power state to an active power state; and in response to exiting the PSM, performing a second power collapse of the applications processor into the low power state while the modem operates in the active power state.
Abstract:
Wireless User Equipment (UEs) are adapted to facilitate uplink transmissions on two or more carriers. According to one example, a wireless user equipment can determine whether a size of data to be transmitted is greater than or less than a predetermined threshold. When the size of the data is less than the predetermined threshold, the wireless user equipment can transmit the data on a primary carrier. When the size of the data is greater than, or equal to the predetermined threshold, the wireless user equipment can transmit an initial portion of the data on the secondary carrier, and any remaining portion of the data can be transmitted on the primary carrier. Other aspects, embodiments, and features are also included.
