Title: Prioritizing communications for multiple radio access technologies

Description:
FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for prioritizing communications for multiple radio access technologies. 
     BACKGROUND 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). 
     A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. 
     SUMMARY 
     Some aspects described herein relate to a method of wireless communication performed by a mobile station. The method may include determining, by the mobile station, that transmission of one or more first messages, to a wireless device and via a first radio access technology (RAT), does not meet a transmission quality threshold associated with the one or more first messages, where the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT. The method may include adjusting, by the mobile station, a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages.

     DETAILED DESCRIPTION 
     Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) RAT, aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G). 
       FIG.  1    is a diagram illustrating an example of a wireless network  100 , in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network  100  may include one or more base stations  110  (shown as a BS  110   a,  a BS  110   b,  a BS  110   c,  and a BS  110   d ), a user equipment (UE)  120  or multiple UEs  120  (shown as a UE  120   a,  a UE  120   b,  a UE  120   c,  a UE  120   d,  and a UE  120   e ), and/or other network entities. A base station  110  is an entity that communicates with UEs  120 . A base station  110  (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station  110  may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station  110  and/or a base station subsystem serving this coverage area, depending on the context in which the term is used. 
     A base station  110  may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs  120  with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs  120  with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs  120  having association with the femto cell (e.g., UEs  120  in a closed subscriber group (CSG)). A base station  110  for a macro cell may be referred to as a macro base station. A base station  110  for a pico cell may be referred to as a pico base station. A base station  110  for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in  FIG.  1   , the BS  110   a  may be a macro base station for a macro cell  102   a,  the BS  110   b  may be a pico base station for a pico cell  102   b,  and the BS  110   c  may be a femto base station for a femto cell  102   c . A base station may support one or multiple (e.g., three) cells. 
     In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station  110  that is mobile (e.g., a mobile base station). In some examples, the base stations  110  may be interconnected to one another and/or to one or more other base stations  110  or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     The wireless network  100  may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station  110  or a UE  120 ) and send a transmission of the data to a downstream station (e.g., a UE  120  or a base station  110 ). A relay station may be a UE  120  that can relay transmissions for other UEs  120 . In the example shown in  FIG.  1   , the BS  110   d  (e.g., a relay base station) may communicate with the BS  110   a  (e.g., a macro base station) and the UE  120   d  in order to facilitate communication between the BS  110   a  and the UE  120   d.  A base station  110  that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. 
     The wireless network  100  may be a heterogeneous network that includes base stations  110  of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations  110  may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network  100 . For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts). 
     A network controller  130  may couple to or communicate with a set of base stations  110  and may provide coordination and control for these base stations  110 . The network controller  130  may communicate with the base stations  110  via a backhaul communication link. The base stations  110  may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. 
     The UEs  120  may be dispersed throughout the wireless network  100 , and each UE  120  may be stationary or mobile. A UE  120  may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE  120  may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium. 
     Some UEs  120  may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs  120  may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs  120  may be considered a Customer Premises Equipment. A UE  120  may be included inside a housing that houses components of the UE  120 , such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. 
     In general, any number of wireless networks  100  may be deployed in a given geographic area. Each wireless network  100  may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. 
     In some examples, two or more UEs  120  (e.g., shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (e.g., without using a base station  110  as an intermediary to communicate with one another). For example, the UEs  120  may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     Devices of the wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network  100  may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. 
     The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band. 
     With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     In some aspects, the mobile station (e.g., UE  120 ) may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may determine that transmission of one or more first messages, to a wireless device and via a first RAT, does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT; and adjust a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein.

Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     In some aspects, the wireless device (e.g., base station  110  or UE  120 ) may include a communication manager  140  or  150 . As described in more detail elsewhere herein, the communication manager  140  or  150  may receive, from a mobile station, data indicating that one or more first messages are to be transmitted via a first RAT with an adjusted prioritization, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT; and adjust, based at least in part on receiving the data, one or more reception opportunities associated with at least one of the one or more first messages or the one or more second messages to prioritize reception of the one or more first messages over the one or more second messages. Additionally, or alternatively, the communication manager  140  or  150  may perform one or more other operations described herein. 
     As indicated above,  FIG.  1    is provided as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIG.  2    is a diagram illustrating an example  200  of a base station  110  in communication with a UE  120  in a wireless network  100 , in accordance with the present disclosure. The base station  110  may be equipped with a set of antennas  234   a  through  234   t , such as T antennas (T≥1). The UE  120  may be equipped with a set of antennas  252   a  through  252   r,  such as R antennas (R≥1). 
     At the base station  110 , a transmit processor  220  may receive data, from a data source  212 , intended for the UE  120  (or a set of UEs  120 ). The transmit processor  220  may select one or more modulation and coding schemes (MCSs) for the UE  120  based at least in part on one or more channel quality indicators (CQIs) received from that UE  120 . The base station  110  may process (e.g., encode and modulate) the data for the UE  120  based at least in part on the MCS(s) selected for the UE  120  and may provide data symbols for the UE  120 . The transmit processor  220  may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor  220  may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems  232  (e.g., T modems), shown as modems  232   a  through  232   t.  For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem  232 . Each modem  232  may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem  232  may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems  232   a  through  232   t  may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas  234  (e.g., T antennas), shown as antennas  234   a  through  234   t.    
     At the UE  120 , a set of antennas  252  (shown as antennas  252   a  through  252   r ) may receive the downlink signals from the base station  110  and/or other base stations  110  and may provide a set of received signals (e.g., R received signals) to a set of modems  254  (e.g., R modems), shown as modems  254   a  through  254   r.  For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem  254 . Each modem  254  may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem  254  may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from the modems  254 , may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE  120  to a data sink  260 , and may provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE  120  may be included in a housing  284 . 
     The network controller  130  may include a communication unit  294 , a controller/processor  290 , and a memory  292 . The network controller  130  may include, for example, one or more devices in a core network. The network controller  130  may communicate with the base station  110  via the communication unit  294 . 
     One or more antennas (e.g., antennas  234   a  through  234   t  and/or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of  FIG.  2   . 
     On the uplink, at the UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor  280 . The transmit processor  264  may generate reference symbols for one or more reference signals. The symbols from the transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by the modems  254  (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station  110 . In some examples, the modem  254  of the UE  120  may include a modulator and a demodulator. In some examples, the UE  120  includes a transceiver. The transceiver may include any combination of the antenna(s)  252 , the modem(s)  254 , the MIMO detector  256 , the receive processor  258 , the transmit processor  264 , and/or the TX MIMO processor  266 . The transceiver may be used by a processor (e.g., the controller/processor  280 ) and the memory  282  to perform aspects of any of the methods described herein (e.g., with reference to  FIGS.  3 - 13   ). 
     At the base station  110 , the uplink signals from UE  120  and/or other UEs may be received by the antennas  234 , processed by the modem  232  (e.g., a demodulator component, shown as DEMOD, of the modem  232 ), detected by a MIMO detector  236  if applicable, and further processed by a receive processor  238  to obtain decoded data and control information sent by the UE  120 . The receive processor  238  may provide the decoded data to a data sink  239  and provide the decoded control information to the controller/processor  240 . The base station  110  may include a communication unit  244  and may communicate with the network controller  130  via the communication unit  244 . The base station  110  may include a scheduler  246  to schedule one or more UEs  120  for downlink and/or uplink communications. In some examples, the modem  232  of the base station  110  may include a modulator and a demodulator. In some examples, the base station  110  includes a transceiver. The transceiver may include any combination of the antenna(s)  234 , the modem(s)  232 , the MIMO detector  236 , the receive processor  238 , the transmit processor  220 , and/or the TX MIMO processor  230 . The transceiver may be used by a processor (e.g., the controller/processor  240 ) and the memory  242  to perform aspects of any of the methods described herein (e.g., with reference to  FIGS.  3 - 13   ). 
     The controller/processor  240  of the base station  110 , the controller/processor  280  of the UE  120 , and/or any other component(s) of  FIG.  2    may perform one or more techniques associated with prioritizing communications for multiple radio access technologies, as described in more detail elsewhere herein. For example, the controller/processor  240  of the base station  110 , the controller/processor  280  of the UE  120 , and/or any other component(s) of  FIG.  2    may perform or direct operations of, for example, process  900  of  FIG.  9   , process  1000  of  FIG.  10   , process  1100  of  FIG.  11   , and/or other processes as described herein. The memory  242  and the memory  282  may store data and program codes for the base station  110  and the UE  120 , respectively. In some examples, the memory  242  and/or the memory  282  may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station  110  and/or the UE  120 , may cause the one or more processors, the UE  120 , and/or the base station  110  to perform or direct operations of, for example, process  900  of  FIG.  9   , process  1000  of  FIG.  10   , process  1100  of  FIG.  11   , and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples. 
     In some aspects, the mobile station includes means for determining, by the mobile station, that transmission of one or more first messages, to a wireless device and via a first RAT, does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT; and/or means for adjusting, by the mobile station, a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages. In some aspects, the means for the mobile station to perform operations described herein may include, for example, one or more of communication manager  150 , transmit processor  220 , TX MIMO processor  230 , modem  232 , antenna  234 , MIMO detector  236 , receive processor  238 , controller/processor  240 , memory  242 , or scheduler  246 .

     In some aspects, the mobile station includes means for determining, by the mobile station, that transmission of one or more first messages, to a wireless device and via a first RAT, does not meet a transmission quality threshold, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT; and/or means for transmitting, by the mobile station and to the wireless device and via the second RAT, the one or more first messages. In some aspects, the means for the mobile station to perform operations described herein may include, for example, one or more of communication manager  150 , transmit processor  220 , TX MIMO processor  230 , modem  232 , antenna  234 , MIMO detector  236 , receive processor  238 , controller/processor  240 , memory  242 , or scheduler  246 .

     In some aspects, the wireless device includes means for receiving, by the wireless device and from a mobile station, data indicating that one or more first messages are to be transmitted via a first RAT with an adjusted prioritization, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT; and/or means for adjusting, by the wireless device and based at least in part on receiving the data, one or more reception opportunities associated with at least one of the one or more first messages or the one or more second messages to prioritize reception of the one or more first messages over the one or more second messages. In some aspects, the means for the wireless device to perform operations described herein may include, for example, one or more of communication manager  150 , transmit processor  220 , TX MIMO processor  230 , modem  232 , antenna  234 , MIMO detector  236 , receive processor  238 , controller/processor  240 , memory  242 , or scheduler  246 . In some aspects, the means for the wireless device to perform operations described herein may include, for example, one or more of communication manager  140 , antenna  252 , modem  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , TX MIMO processor  266 , controller/processor  280 , or memory  282 . 
     While blocks in  FIG.  2    are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components.

     As indicated above,  FIG.  2    is provided as an example. Other examples may differ from what is described with regard to  FIG.  2   . 
       FIG.  3    is a diagram illustrating an example  300  of sidelink communications, in accordance with the present disclosure. 
     As shown in  FIG.  3   , a first UE  305 - 1  may communicate with a second UE  305 - 2  (and one or more other UEs  305 ) via one or more sidelink channels  310 . The UEs  305 - 1  and  305 - 2  may communicate using the one or more sidelink channels  310  for P2P communications, D2D communications, V2X communications (e.g., which may include V2V communications, V2I communications, and/or V2P communications) and/or mesh networking. In some aspects, the UEs  305  (e.g., UE  305 - 1  and/or UE  305 - 2 ) may correspond to one or more other UEs described elsewhere herein, such as UE  120 . In some aspects, the one or more sidelink channels  310  may use a PC5 interface and/or may operate in a high frequency band (e.g., the 5.9 GHz band). Additionally, or alternatively, the UEs  305  may synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols) using global navigation satellite system (GNSS) timing. 
     As further shown in  FIG.  3   , the one or more sidelink channels  310  may include a physical sidelink control channel (PSCCH)  315 , a physical sidelink shared channel (PSSCH)  320 , and/or a physical sidelink feedback channel (PSFCH)  325 . The PSCCH  315  may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and/or a physical uplink control channel (PUCCH) used for cellular communications with a base station  110  via an access link or an access channel The PSSCH  320  may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PUSCH) used for cellular communications with a base station  110  via an access link or an access channel For example, the PSCCH  315  may carry sidelink control information (SCI)  330 , which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, and/or spatial resources) where a transport block (TB)  335  may be carried on the PSSCH  320 . The TB  335  may include data. The PSFCH  325  may be used to communicate sidelink feedback  340 , such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK/NACK) information), transmit power control (TPC), and/or a scheduling request (SR). 
     Although shown on the PSCCH  315 , in some aspects, the SCI  330  may include multiple communications in different stages, such as a first stage SCI (SCI-1) and a second stage SCI (SCI-2). The SCI-1 may be transmitted on the PSCCH  315 . The SCI-2 may be transmitted on the PSSCH  320 . The SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and/or spatial resources) on the PSSCH  320 , information for decoding sidelink communications on the PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH demodulation reference signal (DMRS) pattern, an SCI format for the SCI-2, a beta offset for the SCI-2, a quantity of PSSCH DMRS ports, and/or a modulation and coding scheme (MCS). The SCI-2 may include information associated with data transmissions on the PSSCH  320 , such as a hybrid automatic repeat request (HARQ) process ID, a new data indicator (NDI), a source identifier, a destination identifier, and/or a channel state information (CSI) report trigger. 
     In some aspects, the one or more sidelink channels  310  may use resource pools. For example, a scheduling assignment (e.g., included in SCI  330 ) may be transmitted in sub-channels using specific resource blocks (RBs) across time. In some aspects, data transmissions (e.g., on the PSSCH  320 ) associated with a scheduling assignment may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmissions are not transmitted on adjacent RBs. 
     In some aspects, a UE  305  may operate using a sidelink transmission mode (e.g., Mode 1) where resource selection and/or scheduling is performed by a base station  110 . For example, the UE  305  may receive a grant (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as for configured grants) from the base station  110  for sidelink channel access and/or scheduling. In some aspects, a UE  305  may operate using a transmission mode (e.g., Mode 2) where resource selection and/or scheduling is performed by the UE  305  (e.g., rather than a base station  110 ). In some aspects, the UE  305  may perform resource selection and/or scheduling by sensing channel availability for transmissions. For example, the UE  305  may measure a received signal strength indicator (RSSI) parameter (e.g., a sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, may measure a reference signal received power (RSRP) parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, and/or may measure a reference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and may select a channel for transmission of a sidelink communication based at least in part on the measurement(s). 
     Additionally, or alternatively, the UE  305  may perform resource selection RSRP and/or scheduling using SCI  330  received in the PSCCH  315 , which may indicate occupied resources and/or channel parameters. Additionally, or alternatively, the UE  305  may perform resource selection and/or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE  305  can use for a particular set of subframes). 
     In the transmission mode where resource selection and/or scheduling is performed by a UE  305 , the UE  305  may generate sidelink grants, and may transmit the grants in SCI  330 . A sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission on the PSSCH  320  (e.g., for TBs  335 ), one or more subframes to be used for the upcoming sidelink transmission, and/or a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission. In some aspects, a UE  305  may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of a sidelink transmission. Additionally, or alternatively, the UE  305  may generate a sidelink grant for event-driven scheduling, such as for an on-demand sidelink message. 
     As indicated above,  FIG.  3    is provided as an example. Other examples may differ from what is described with respect to  FIG.  3   . 
       FIG.  4    is a diagram illustrating an example  400  of sidelink communications and access link communications, in accordance with the present disclosure. 
     As shown in  FIG.  4   , a transmitter (Tx)/receiver (Rx) UE  405  and an Rx/Tx UE  410  may communicate with one another via a sidelink, as described above in connection with  FIG.  3   . As further shown, in some sidelink modes, a base station  110  may communicate with the Tx/Rx UE  405  via a first access link. Additionally, or alternatively, in some sidelink modes, the base station  110  may communicate with the Rx/Tx UE  410  via a second access link. The Tx/Rx UE  405  and/or the Rx/Tx UE  410  may correspond to one or more UEs described elsewhere herein, such as the UE  120  of  FIG.  1   . Thus, a direct link between UEs  120  (e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between a base station  110  and a UE  120  (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be transmitted via the sidelink, and access link communications may be transmitted via the access link. An access link communication may be either a downlink communication (from a base station  110  to a UE  120 ) or an uplink communication (from a UE  120  to a base station  110 ). 
     As indicated above,  FIG.  4    is provided as an example. Other examples may differ from what is described with respect to  FIG.  4   . 
       FIG.  5    is a diagram illustrating an example  500  of V2X communications using multiple RATs, in accordance with the present disclosure. As shown in  FIG.  5   , two UEs (e.g., UEs  120 - 1  and  120 - 2 , each associated with a vehicle) may communicate with one another using multiple links associated with different RATs (e.g., an NR link and an LTE link). 
     In some aspects, different V2X links may be used to transmit different types of messages, with different priorities (e.g., different QoS), and/or for different channels. For example, the UEs may use an LTE link to communicate messages associated with a basic safety application (e.g., enabling the sharing of vehicle status information, such as vehicle position, velocity, heading, acceleration, and/or the like). The basic safety application messages may be generated and transmitted periodically (e.g., 100 ms of periodicity). As another example, the UEs may use an NR link to transmit advanced use case (UC) application messages (e.g., enabling negotiated messages between vehicles and infrastructure for lane merging, among other examples). Depending on the conditions associated with the links, in some aspects, the NR link may often be associated with a higher reliability and a lower latency. 
     When transmitting communications to one another via LTE and NR links, an application layer associated with a UE may provide lower layers with a priority associated with the communications, such as a QoS value, using a model that corresponds to the type of link. Based at least in part on the priority, and configuration of the UE, the UE may attempt transmission of the communication. For example, in an LTE link, ProSe Per-Packet Priority (PPPP) and ProSe Per-Packet Reliability (PPPR) may be provided by the application layer, and the UE may map the communication to a corresponding bearer. As another example, in an NR link, priority information (e.g., QoS information) may be provided by the application layer and mapped on a QoS identifier (5QI) based at least in part on the priority information and UE configuration. The communication may then be mapped to a corresponding radio bearer by the service data adaptation protocol (SDAP) layer. 
     When scheduling a V2X communication, a UE may transmit sidelink control information (SCI) that indicates a time domain resource assignment (TDRA) for the communication. For example, the SCI may include a TDRA field that includes a TDRA index value. The TDRA index value may indicate a row index of a corresponding TDRA table, and the row index may correspond to a set of TDRA parameters (sometimes referred to as scheduling parameters or scheduling information). The Tx UE and Rx UE may use the TDRA parameters for the scheduled communications. In some aspects, the TDRA parameters may indicate a scheduling offset (e.g., in number of slots) between a slot containing the scheduling SCI (that schedules a V2X communication) and the slot containing the scheduled V2X communication (scheduled by the scheduling SCI). Other TDRA parameters may include a parameter indicating a starting symbol for the V2X communication, a parameter indicating a length (e.g., a number of consecutive symbols) of the V2X communication (e.g., in the indicated slot), and/or the like. 
     In some aspects, UEs may communicate with one another using multiple RATs using time-division multiplexing. For example, each UE may be aware of (e.g., based at least in part on SCI and/or TDRA) the frame indices of communications (e.g., communications channels, signals, and/or the like) scheduled for transmission to/from the UE. The UE may transmit, or receive, communications such that a subframe boundary of one communication is aligned with the subframe boundary of another communication. 
     While the example  500  depicts V2X communications between UEs using multiple RATs, other examples may include other time-division multiplexed sidelink communications between UEs using multiple RATs and/or time-division multiplexed downlink/uplink communications between a UE and a base station using multiple RATs. As indicated above,  FIG.  5    is provided as an example. Other examples may differ from what is described with respect to  FIG.  5   . 
     In situations where a UE is communicating with another wireless device (e.g., another UE or a base station) using multiple RATs, the UE may occasionally be unable to guarantee sufficient transmission or reception opportunities for one or more of the multiple RATs (e.g., resource starvation). This may lead to messages being dropped, and in some cases, continuous dropping of messages that are of lower priority. For example, the UE may continuously drop basic safety application messages that are associated with an LTE link due to transmission and/or reception of advanced UC messages and/or other messages that might collide with (e.g., interfere with) transmission and/or reception of the basic safety application messages (e.g., due to the advance UC messages and/or other messages having a priority, or QoS, higher than the basic safety application messages). The message handling priority across multiple RATs may lead to dropped transmissions and/or reception opportunities that fall below a target transmission and/or reception quality threshold. Dropped transmissions and/or reception opportunities may lead to wireless devices wasting resources, including wasting network resources, processing resources, power resources, and/or the like (e.g., due to re-transmission attempts and wasted reception opportunities). 
     Some techniques and apparatuses described herein enable a UE to communicate with another wireless device via multiple RATs simultaneously (e.g., using a time-division multiplexing), while addressing dropped transmission and reception opportunities by switching message priorities and/or switching RATs used to transmit particular messages. For example, a UE may adjust prioritization (e.g., QoS) associated with one or more messages, to be communicated via a first RAT, that are not going to meet a transmission quality threshold (e.g., a transmission periodicity threshold) to cause the message(s) to be transmitted with a higher priority than other messages. As another example, the UE may switch the RAT used for transmission of the message(s) to enable a different RAT (e.g., one associated with higher priority transmissions) to transmit the message(s). As a result, the UE may change the priority and/or RAT used to transmit and/or receive messages, which may provide improved transmission and/or reception periodicity for messages transmitted via different RATs. This may lead to wireless devices having fewer dropped transmissions and/or reception opportunities and may lead to improved wireless device resource usage, including improved usage and/or efficiency of network resources, processing resource, power resources, and/or the like (e.g., due to a reduction in re-transmission attempts and wasted reception opportunities). 
       FIG.  6    is a diagram illustrating an example  600  associated with prioritizing communications for multiple RATs, in accordance with the present disclosure. As shown in  FIG.  6   , an Rx UE (e.g., UE  120 ) may communicate with a Tx UE via one or more sidelink communications. In some aspects, the Tx UE and/or Rx UE may communicate with another wireless device, such as a base station (e.g., base station  110 ) via one or more uplink and/or downlink communications (e.g., in addition to, or in place of, communicating with another UE). The UEs and the base station may be part of a wireless network (e.g., wireless network  100 ). 
     As shown by reference number  605 , the Rx UE and Tx UE may establish communications with one another via multiple RATs. For example, as described herein, the Rx/Tx UEs may establish sidelink communications via 3G RAT, 4G RAT, and/or 5G RAT, among other examples. By way of example, the Rx/Tx UEs may be in V2X communication with one another via a 4G RAT and a 5G RAT, where the 4G RAT is used for one set of message types (e.g., including basic safety application messages), and the 5G RAT is used for another set of message types (e.g., including advanced UC application messages). 
     As shown by reference number  610   a,  in some aspects, the Rx UE may monitor a measure of reception quality, such as a measure of reception periodicity, associated with one or more first messages. In some aspects, as shown by reference number  610   b,  the Tx UE may monitor a measure of transmission quality (e.g., a measure of transmission periodicity). The first messages may be messages that are to be transmitted, by the Tx UE and to the Rx UE, using a first RAT. In some aspects, the Rx UE may monitor reception periodicity by determining how often the Rx UE is receiving, or is scheduled to receive, the first messages (e.g., monitoring a number of reception opportunities for a particular time period). In some aspects, the Tx UE may monitor transmission periodicity by determining how often the Tx UE is transmitting, or is scheduled to transmit, the first messages (e.g., monitoring a number of transmissions for a particular period of time). For example, periodicity may be monitored by using a timer and/or a counter to determine the number of transmissions and/or reception opportunities over a particular period of time. 
     As shown by reference number  615   a,  in some aspects, the Rx UE may determine that reception of the first messages does not satisfy a reception quality threshold. In some aspects, as shown by reference number  615   b,  the Tx UE may determine that transmission of the first messages does not satisfy a transmission quality threshold. For example, the first messages may be associated with a target periodicity (e.g., based at least in part on Rx/Tx UE configuration, one or more QoS rules, requirements of an application associated with the first messages, and/or the like). In some aspects, the transmission and/or reception quality thresholds may be based at least in part on the target periodicity. For example, the transmission and/or reception quality thresholds may be a periodicity threshold that matches the target periodicity or that is below the target periodicity by a particular amount (e.g., 90% of the target periodicity, 75% of the target periodicity, and/or the like). 
     In some aspects, the Rx/Tx UE may determine that the reception and/or transmission of the first messages does not satisfy the reception and/or transmission quality threshold (e.g., the threshold periodicity) based at least in part on a schedule indicating the reception or transmission periodicity (e.g., currently) and a target reception or transmission periodicity. In a situation where the schedule indicates that the first messages will not be received and/or transmitted with the target reception or transmission periodicity, the Rx/Tx UE may determine that the reception and/or transmission quality threshold is not met. 
     In some aspects, the Rx/Tx UE may determine that the reception and/or transmission of the first messages does not satisfy the reception and/or transmission quality threshold (e.g., the threshold periodicity) based at least in part on monitoring reception or transmission periodicity, as described herein. For example, in a situation where monitoring the reception or transmission periodicity indicates that the first messages will not be received and/or transmitted with the target reception or transmission periodicity, the Rx/Tx UE may determine that the reception and/or transmission quality threshold is not met. 
     As shown by reference number  620 , in some aspects, the Rx UE may transmit, and the Tx UE may receive, a request to adjust prioritization of the first messages. The request may be based at least in part on the periodicity (e.g., based at least in part on scheduling and/or monitoring, as described herein) not satisfying the reception periodicity threshold. For example, the request may include SCI or other information that indicates, to the Tx UE, that the priority of the first messages should be adjusted (e.g., to satisfy a target periodicity). 
     As shown by reference number  625 , in some aspects, the Tx UE may adjust a prioritization of the first messages or one or more second messages (e.g., associated with another RAT and/or another priority different from the priority of the first messages) to prioritize the transmission of the first messages over the second messages. For example, the Tx UE may adjust a QoS of the first messages (e.g., increasing the QoS) to prioritize transmission of the first messages over the second messages. As another example, the Tx UE may adjust a QoS of the second messages (e.g., decreasing the QoS) to prioritize transmission of the first messages over the second messages. 
     In some aspects, the Tx UE may map the first messages for transmission via a second RAT. For example, the second RAT may be associated with a higher priority, better channel conditions, and/or the like, relative to the first RAT associated with transmission of the first messages. By mapping the first messages for transmission via the second RAT, the Tx UE will transmit the first messages with a higher priority than the first messages would have had being transmitted by the first RAT. In some aspects, one or more second messages associated with the second RAT may have a lower priority (e.g., lower QoS) than the first messages, enabling both the first messages and the second messages to be transmitted via the second RAT, but the first messages having a higher priority (e.g., in the foregoing situation). 
     As shown by reference number  630 , in some aspects, the Tx UE may transmit, and the Rx UE may receive, data indicating the adjusted prioritization. For example, in a situation where the Tx UE adjusts the priority of the first messages (or the second messages), the Tx UE may notify the Rx UE of the adjustment (e.g., to enable the Rx UE to update one or more reception opportunities, if appropriate). 
     In some aspects, the Tx UE may transmit, and the Rx UE may receive, data indicating a change in transmission of the one or more first messages from the first RAT to the second RAT. For example, in a situation where the Tx UE changes the mapping of the first messages from the first RAT to the second RAT, the Tx UE may notify the Rx UE of the change (e.g., to enable the Rx UE to update one or more reception opportunities, if appropriate). 
     As shown by reference number  635 , the Rx UE may adjust one or more reception opportunities associated with the first messages and/or the second messages to prioritize reception of the first messages over the second messages. For example, in a situation where the first messages change priority (e.g., QoS), the reception opportunities associated with the first messages may be updated to reflect the change in priority. As another example, in a situation where the first messages are being transmitted via a different RAT, the Rx UE may also need to adjust reception opportunities to receive the first messages via the different RAT. 
     As shown by reference number  640 , the Tx UE may transmit, and the Rx UE may receive, the one or more first messages. In some aspects, the first messages may be transmitted and/or received with adjusted prioritization, as described herein. In some aspects, the first messages may be transmitted and/or received with an adjusted mapping, as described herein (e.g., from a first RAT to a second RAT). 
     As shown by reference number  645 , the Tx UE may determine, after transmitting the one or more first messages, that an adjustment condition is satisfied. For example, the Tx UE may determine that the reason for the adjustment no longer applies. For example, in a situation where the transmission quality threshold was previously not satisfied, the adjustment condition may be satisfaction of the transmission quality threshold. By way of example, the Tx UE may determine that the adjustment condition is satisfied based at least in part on transmission of the first messages meeting a transmission periodicity threshold. 
     In some aspects, the Rx UE (in addition to, or as an alternative to the Tx UE) may determine, after receiving the one or more first messages, that an adjustment condition is satisfied. For example, the adjustment condition may be satisfaction of the reception quality threshold. By way of example, the Rx UE may determine that adjustment condition is satisfied based at least in part on reception of the first messages meeting a transmission periodicity threshold. 
     As shown by reference number  650 , in some aspects, the Tx UE may readjust, based at least in part on determining that the adjustment condition is satisfied, the prioritization to prioritize transmission of the one or more second messages over one or more subsequent messages associated with the first set of messages (e.g., future transmissions of messages associated with the same application, RAT, message type, and/or the like of the first messages). For example, the Tx UE may readjust the QoS of the first messages (e.g., to a prior QoS level, a default QoS level, or the like) to end prioritization of the first messages. 
     In some aspects, the Tx UE may remap one or more subsequent messages, associated with the one or more first messages, for transmission via the first RAT. For example, in a situation where the Tx UE changed the mapping of the first message from the first RAT to the second RAT, the Tx UE may change the mapping back, such that future messages are transmitted via the first RAT. 
     In some aspects, the Rx UE may transmit, to the Tx UE, data indicating that the Tx UE should readjust the prioritization of the subsequent messages and/or remap the subsequent messages. 
     While the example  600  does not indicate a particular channel (e.g., data channel, physical channel, and/or the like), the first messages and/or second messages may be associated with the same channel or different channels. For example, the first messages may be sidelink control channel messages, while the second messages may be sidelink data channel messages. In some aspects, messages that may be prioritized may include various reference signals and channel data, such as reference signals, synchronization signals, control channel information, broadcast channel information, feedback channel information, data channel information, and/or the like. In some aspects, new transmissions may be prioritized differently from retransmissions. 
     In some aspects, certain messages may be assigned a highest priority to enable transmission and/or reception with the highest priority. For example, channels and/or signals used for maintenance of the physical layer connection, such as reference signals, synchronization signals, broadcast channel, and/or the like, may be assigned a highest QoS. In this situation, the methods described herein may be used to prioritize transmission of the messages associated with maintenance of the physical layer connection. 
     In some aspects, more than one type of message may not satisfy the reception and/or transmission quality threshold. In this situation, the Tx/Rx UE may determine which message(s) to prioritize based at least in part on one or more RAT characteristics of the RATs used to transmit the messages. For example, the Tx/Rx UE may determine to prioritize messages based at least in part on a radio identifier, such that a higher identifier (e.g., later evolution) may be prioritized over a lower identifier (e.g., message for transmission via 5G may be prioritized over messages for transmission via 4G). As another example, the Tx/Rx UE may determine to prioritize messages based at least in part on transmission gap between messages. For example, the message with a longer gap since a prior transmission of related messages (e.g., for the same application, on the same RAT, and/or the like) may be prioritized over a message with a shorter gap. Other RAT characteristics or combinations of characteristics may also be used to determine which messages, associated with which RATs, should be prioritized when multiple messages are not meeting transmission and/or reception quality thresholds. 
     As indicated above,  FIG.  6    is provided as an example. Other examples may differ from what is described with respect to  FIG.  6   . 
       FIG.  7    is a diagram illustrating an example  700  associated with adjusting message priority to change transmission periodicity, in accordance with the present disclosure. As shown in  FIG.  7   , a Tx UE may be using time-division multiplexing to transmit messages for a first application (e.g., a basic safety application) and a second application (e.g., an advanced UC application) via different RATs. 
     As shown in the example  700 , the priority (e.g., QoS) associated with the advanced UC application and second radio (e.g., the NR radio) may cause basic safety application messages (represented by vertical lines and arrows as they are handled by the application and physical layers) to be de-prioritized when advanced UC application messages are being transmitted, which may lead to dropped transmissions (each indicated by X). After the first basic safety application message is dropped, the Tx UE may adjust the priority of the basic safety application messages and/or the advanced UC application messages (and/or their corresponding radios) to cause at least some of the basic safety application messages to be transmitted. As seen in the example  700 , the Tx UE can switch prioritization back and forth, such that transmission of one type of message does not starve transmission of another type of message. 
     As indicated above,  FIG.  7    is provided as an example. Other examples may differ from what is described with respect to  FIG.  7   . 
       FIG.  8    is a diagram illustrating an example  800  associated with adjusting message priority to change transmission periodicity, in accordance with the present disclosure. As shown in  FIG.  8   , a Tx UE may be using time-division multiplexing to transmit messages for a first application (e.g., a basic safety application) and a second application (e.g., an advanced UC application) via different RATs. 
     As shown in the example  800 , the Tx UE may be transmitting basic safety application messages (represented by solid vertical lines and arrows) using LTE and advanced UC application messages (represented by dotted vertical lines and arrows) using NR. In a situation where higher priority advanced UC application messages cause a transmission quality issue with the basic safety application messages (e.g., dropped messages indicated by X), the Tx UE switching the mapping of basic safety application messages to transmit the basic safety application messages via NR instead of LTE. The basic safety application messages may be remapped periodically, e.g., to ensure a transmission quality threshold is satisfied for both the basic safety application message and the advanced UC application messages. 
     As indicated above,  FIG.  8    is provided as an example. Other examples may differ from what is described with respect to  FIG.  8   .

     As shown in  FIG.  9   , in some aspects, process  900  may include determining that transmission of one or more first messages, to a wireless device and via a first RAT, does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT (block  910 ). For example, the mobile station (e.g., using communication manager  140  and/or determination component  1208 , depicted in  FIG.  12   ) may determine that transmission of one or more first messages, to a wireless device and via a first RAT, does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT, as described above.
