摘要: Methods, systems, and devices for wireless communication in a multi-connectivity user equipment (UE) are described. The UE may communicate with one or more base stations via a first radio access technology (RAT). The UE may determine whether the UE is in a selected state. The selected state may correspond to one or more modes of operation (e.g., a doze mode, a relaxed doze mode, an active WiFi communication mode, a low battery mode). The UE may disable communication via a second RAT in response to determining that the UE is in the selected state. The UE may continue to communicate via the first RAT.

摘要: In an aspect, a user equipment (UE) may receive an uplink (UL) grant (e.g., dynamic UL grant, UL configured grant (CG)) from a network, but may decide to skip the UL grant altogether or not transmit any user plane data on the UL grant. In such instances, the UE may maintain or expedite expiration associated with one or more timers (e.g., discontinuous reception (DRX) and bandwidth part (BWP) inactivity timers, secondary cell (SCell) deactivation timer, etc.). The UE may also maintain or expedite expiration associated with one or more timers if it receives downlink (DL) transmission (e.g., DL semi-persistent scheduling (SPS)) from the network that includes no user plane data.

摘要: Modem thermal management may include a state machine monitoring a temperature associated with a modem, setting a mode in response to detection of a change in the temperature with respect to a threshold, and applying a set of one or more thermal mitigation actions associated with a current state of the state machine. The state machine may set a timer in response to detection of the change in temperature and then transition from the current state to another state in response to expiration of the timer. The monitored temperature may be a junction temperature or a skin temperature.

摘要: User equipment (UE) may benefit from power management techniques, for example, in the context of cellular vehicle-to-everything (CV2X) communication. In various aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine whether a first subframe includes at least one sub-channel carrying information intended for the UE, receive the information via at least one receive (Rx) chain associated with the at least one sub-channel when the information intended for the UE is carried on the at least one sub-channel included in the first subframe, and deactivate the at least one Rx chain associated with the at least one sub-channel based on whether the information intended for the UE is absent from the at least one sub-channel included in the first subframe.

摘要: A UE may, responsive to detecting a power-related condition, send a message to induce the master node to release the secondary node. Such a message can include a message reporting a radio link failure of the secondary node, or, if a channel quality indicator is configured for at least some of the secondary cells of the secondary node, reporting a low CQI value so that the network can cease scheduling on such cells. Alternatively, in a carrier aggregation (CA) mode, with the UE connected to a single node comprising a primary cell and one or more secondary cells, the UE may not control which and how many secondary cells with which it communicates. In such a scenario, if such secondary cells are configured for channel quality indicator reporting, the UE may report a low CQI value so that the node will cease scheduling data on such cells.

摘要: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques that may help mitigate service loss for a UE (e.g., in DSDA mode) due to temperature rise. According to certain aspects, a UE detects, while operating in a multi subscriber identity module (SIM) mode with at least a first subscriber (SUB) and a second subscriber (SUB) active on a first radio access technology (RAT), that the UE has reached a first temperature threshold less than a second temperature threshold at which the UE limits service in the first RAT and greater than a third temperature threshold associated with a temperature mitigation level. The UE then takes action to move the first SUB to a second RAT in response to the detecting.

摘要: In some aspects, the present disclosure provides methods, apparatuses, and systems for efficient thermal mitigation while maintaining wireless device performance on a primary component carrier (PCC). Embodiments described may include implementation of target transceiver module configurations, where bandwidth (e.g., PCC bands and secondary component carrier (SCC) bands) may be monitored by a wireless device based on intra-module target configurations and/or inter-module target configurations. An intra-module target configuration may include a target transceiver module monitoring both PCC bands and SCC bands. An inter-module target configuration may include or refer to a plurality of target transceiver modules together monitoring PCC bands and SCC bands. In scenarios where operating temperatures exceed temperature thresholds, target transceiver module configurations may be implemented to transition PCC bands, SCC bands, or both, from a PCC-resident transceiver module to another transceiver module to reduce the operating temperatures of concern. Various additional and alternative aspects are described herein.

摘要: Disclosed are techniques for wireless communication. In an aspect, a UE may partially disable transmissions on a transmission port based on a temperature condition (e.g., chipset temperature or skin temperature exceeding threshold). In a further aspect, the UE may enable the partially disabled transmissions on the transmission port in response to cessation of the temperature condition. In a further aspect, the UE may transmit a capability indication to a base station that indicates that the UE is capable of supporting a transition from a multi-layer (rank-2) communication mode to a single-layer (rank-1) communication mode.
