This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Implicit radio resource control state transitions

A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Control channel for UE power saving

Techniques discussed herein can facilitate one or more enhancements to beam management for a User Equipment (UE) operating in a Discontinuous Reception (DRX) mode. A first set of techniques relates to enhancements to transmission of Scheduling Request(s) (SR(s)) by UEs operating in DRX mode. A second set of techniques relates to enhancements to beam failure detection and recovery by UEs operating in DRX mode. A third set of techniques relates to enhancements to beam measurement and reporting by UEs operating in DRX mode. Various embodiments can employ one or more techniques of the first set of techniques, the second set of techniques, and/or the third set of techniques.

Systems, methods, and mechanisms for performing ROHC header compression on TCP packets with MPTCP option enabled. A compressor may determine that a first portion of the stream of data packets is formatted according to the transmission control protocol (TCP) with a multipath TCP (MPTCP) option enabled. The compressor may establish context with a corresponding decompressor and may operate in one of three modes of compression based on the context. In some embodiments, when the context indicates that the corresponding decompressor supports decompression of TCP data packets with MPTCP option enabled, the compressor may operate in a first or second mode of compression. In some embodiments, when the context indicates that the corresponding decompressor does not support decompression of TCP data packets with MPTCP option enabled, the compressor may operation in a third mode of compression.

ROHC header compression for MPTCP

Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

Inactive mode operations

A method, device, computer readable storage medium and integrated circuit for providing user equipment (UE) capability information to a network. The method includes receiving a request from a network for radio access capabilities of the UE, determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network, determining a number of band combinations that are to be included with a message generated in response to the request, ordering the plurality of band combinations into a prioritized order of band combinations based on at least one priority factor, generating the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message and transmitting the message to the network.
