    Abstract: Mobile devices, base stations, and/or relay stations may implement methods for decreasing required guard bands while also minimizing Adjacent Channel Leakage Ratio, when multiple mobile devices communicate over different respective adjacent specified frequency bands. For communications over at least one specified frequency band of the different respective adjacent frequency bands, a first bandwidth of uplink communications and/or a second bandwidth of downlink communications may be adjusted to differ from each other, and/or a communications bandwidth within the specified frequency band may be adjusted to be of a first size during a first portion of a specified data transmission period and to be of a second size during a second portion of the specified data transmission period, when at least some of the communications over the specified frequency band take place at frequencies adjacent to frequencies at which at least some of the communications take place over another specified frequency band.

    Abstract: Apparatus and methods for time division multiplexing of radio frequency channels in unlicensed radio frequency bands by a wireless device in communication with a cellular wireless network are disclosed. The wireless device obtains, from an eNodeB, a configuration for carrier aggregation using a primary component carrier (PCC) in a licensed radio frequency band and at least one secondary component carrier (SCC) in an unlicensed radio frequency band. The configuration information specifies an “on” time period and an “off” time period for a repetitive time division cycle to use the at least one SCC in the unlicensed radio frequency band. During an “on” time period, the wireless device can transmit or receive using the PCC and the at least one SCC, as scheduled by the eNodeB. During an “off” time period, the wireless device can transmit or receive using the PCC and not using the at least one SCC.

    Abstract: This disclosure relates to use of WLAN virtual interfaces. According to one embodiment, a wireless device may be capable of using a WLAN chipset for user initiated WLAN communication and for cellular offloading WLAN communication. A separate WLAN virtual interface may be established for each type of WLAN communication, including a first WLAN virtual interface between the WLAN chipset and a WLAN connectivity manager executing on an application processor of the wireless device and a second WLAN virtual interface between the WLAN chipset and a cellular connectivity manager executing on the application processor. The virtual interfaces may each use a different IP address, and may either multiplex data onto a shared RF chain in a time-sharing manner or each be provided with their own RF chain to perform WLAN communication.

    Abstract: This application discloses various techniques for call establishment using voice-over LTE (VoLTE) in networks supporting time division (TD) and frequency division duplexed (FDD) LTE communication systems. Such techniques can include systems and methods for mobile-originated calls for a UE in a TD-LTE cell, systems and methods for mobile-terminated calls for a connected UE in a TD-LTE cell and systems and methods for mobile-terminated calls for an idle UE in a TD-LTE cell. These methods and systems can leverage component carriers from a carrier aggregating capable UE to facilitate more efficient and/or effective UE call establishment.

    Abstract: A user equipment (UE), or other network component can operate to generate new radio (NR) communications in millimeter wave (mmW) frequencies. Body proximity sensing (BPS) operations can be performed to determine whether a maximum permissible exposure (MPE) event is triggered. A safe transmit power level associated with the one or more bands can then be used to provide the NR communications. Additionally, determinations of whether various conditions are satisfied to suspend the BPS operations for a period can be evaluated and implemented. The BPS can be configured such that a BPS period of the BPS operations are aligned with a discontinuous reception (DRX) cycle at a beginning of a DRX on-duration of a DRX cycle, wherein the one or more conditions comprise a DRX idle time or state.

    Abstract: Re-connecting to a first radio access network (RAN) of a first radio access technology (RAT) may include initially connecting to the first RAN. A connection associated with a voice call may then be connected that includes connecting to a RAN of a second RAT. In response to the voice call connecting to the second RAN, information for both a frequency and a cell associated with connecting to the first RAN may be stored. An end to the voice call may be identified. In response to determining that the voice call has ended, a timer may be generated at the UE that comprises a specified time period and the timer and the information stored for both the frequency and the cell associated with connecting to the first RAN may be utilized to re-connect to the first RAN.

    Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit a master information block (MIB), a first system information block (SIB), and second SIBs. The first SIB and the second SIBs may be configured for different device categories, and may accordingly have different characteristics. For example, the first SIB may be configured for link budget limited devices, and may include information specific to such devices and/or may exclude information not relevant to such devices or not critical to accessing the cell. In some instances, the first SIB may also include information from the MIB, such that at least some devices may be able to decode the first SIB and gain cell access without decoding the MIB.

    Abstract: Apparatus and methods for time division based communication between a wireless device and a wireless network in a licensed radio frequency (RF) band and an unlicensed RF band are disclosed. The wireless device receives downlink control information (DCI), via a primary component carrier (PCC) of a primary cell (Pcell) in the licensed RF band, indicating downlink (DL) data transmission via a secondary component carrier (SCC) of a secondary cell (Scell) in the unlicensed RF band. The wireless device receives via the SCC part of the DL data transmission and transmits a control message via the PCC in response. The wireless device sends a scheduling request (SR) to the eNodeB and receives uplink (UL) transmission opportunities in a combination of the licensed RF band and the unlicensed RF band. The wireless device performs a clear channel assessment before reserving and transmitting to the eNodeB in the unlicensed RF band.
