Abstract: 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.

Abstract: 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.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Abstract: Systems, apparatuses, and methods for coverage improvements in wireless communication devices. A wireless communication device may be configured to selectively receive one of a plurality of paging signals, or a portion thereof, based on measured or expected coverage quality of communications from a base station. In some scenarios, the wireless communication device may provide an indication to the base station of which paging signal the wireless communication device will attempt to receive, such that the base station may include paging information directed to that UE only in the indicated paging signal. In some scenarios, the base station may include paging information directed to that UE in a plurality of paging signals, each of the paging signals including a different number of repetitions of the paging information. In some scenarios, the UE may receive only a portion of a paging signal including a plurality of repetitions of the paging information.

Abstract: Some embodiments relate to a user equipment device (UE), and associated methods for performing ROHC header compression on TCP packets with MPTCP option enabled. In some embodiments, 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.

Abstract: Systems, apparatuses, and methods for performing cellular relay for an accessory device. A relay device may establish cellular communication with a base station and an accessory device. Establishing communication with the accessory device includes establishing synchronization with the accessory device using a cellular sidelink synchronization channel and a cellular broadcast channel. Establishing communication with the accessory device includes configuring resources for performing communication with the accessory device. Establishing communication with the accessory device includes indicating the resources to the accessory device. The relay device may relay information between the base station and the accessory device using the resources.

Abstract: 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.

Abstract: A user equipment (UE) is configured to connect to a primary cell serving a primary component carrier (PCC) in the licensed spectrum and a secondary cell serving a secondary component carrier (SCC) in an unlicensed spectrum. The UE is configured with a Connected Discontinuous Reception (C-DRX) functionality including an onDuration. The UE determines a first duration based on an amount of time between when a first operation related to an exchange of data over the SCC is to be performed and when the exchange of data over the SCC is likely to occur, determines whether the exchange of data over the SCC is likely to occur during the onDuration based on the first duration and when the exchange of data is unlikely to occur during the onDuration, delays when the first operation is to be performed to cause the exchange of data over the SCC to occur during the onDuration.

Abstract: Techniques are disclosed relating to wireless transmission energy budgets. In some embodiments, an apparatus is configured to determine wireless transmission energy budget for a plurality of time periods. In some embodiments, the apparatus determines budget differently depending on whether it is in a thermal mode or a peak power mode. In some embodiments, the apparatus blanks scheduled wireless transmissions that intersect with the battery signal. In some embodiments, for a time interval subsequent to assertion of the battery signal, the apparatus operates in the peak power mode and determines energy budget for periods based on an amount of energy used for wireless transmissions in a most recent period in which transmissions were blanked in response to the battery signal. In some embodiments, in the thermal mode, the energy budget is based on thermal information for the apparatus, but may also allow carryover of unused budget from previous periods.
