Abstract
Description
Technical Field
[0001] The following relates to wireless communications, including the quasi-co-location (QCL) assumption of simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH). Background Art
[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems, such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread spectrum orthogonal frequency division multiplexing (DFT-S-OFDM).
[0003] A wireless multiple-access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communications for multiple communication devices, which may be further referred to as user equipment (UE). In some wireless multiple-access communication systems, a UE may receive a semi-static configuration of a beam for uplink control transmissions (such as physical uplink control channel (PUCCH) transmissions). In some embodiments, a UE may receive dynamic grants for different beams for uplink data transmissions (such as physical uplink shared channel (PUSCH) transmissions). The UE may use different beams to send uplink control transmissions and uplink data transmissions through the UE's antenna panel. Summary of the Invention

[0045] The following description is directed to certain embodiments for the purpose of describing the innovative aspects of the present disclosure. However, one of ordinary skill in the art will readily recognize that the teachings herein can be applied in a variety of different ways. The described embodiments can be implemented in any device, system, or network capable of transmitting and receiving RF signals in accordance with any of the IEEE 16.11 standards, or any of the IEEE 802.11 standards, or any of the IEEE 16.11 standards. Standard, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband CDMA (W-CDMA), Evolution-Data Optimized (EV-DO), 1xEV-DO, EV-DO Release A, EV-DO Release B, High Speed Packet Access (HSPA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution (LTE), AMPS or other known signals used to communicate within a wireless, cellular or Internet of Things (IoT) network, such as a system utilizing 3G, 4G or 5G technology or further implementations thereof.
[0046] Various aspects of the present disclosure are described in the context of wireless communication systems. Generally, the described techniques provide various mechanisms for simultaneously transmitting uplink control transmissions and uplink data transmissions that at least partially overlap in time. In uplink transmissions on a single beam, a user equipment (UE) can select a single beam over which to transmit both the uplink control transmission and the uplink data transmission.
[0047] A UE may receive a configuration message indicating a first beam associated with an uplink control transmission, such as a physical uplink control channel (PUCCH) transmission. The UE may receive downlink control information (DCI) including a grant for an uplink data transmission, such as a physical uplink shared channel (PUSCH) transmission, the DCI indicating a second beam associated with the uplink data transmission. In one aspect, the UE may select the first beam or the second beam for transmitting both the uplink control transmission and the uplink data transmission based on a temporal overlap between the uplink control transmission and the uplink data transmission. In some aspects, the UE may select the first beam or the second beam based on a set of rules or criteria. In an example, the UE may select between the first beam and the second beam based on a first priority associated with the first beam and a second priority associated with the second beam. The priority associated with the beam may include a physical layer (PHY) priority. The UE may use the selected first beam or the second beam to transmit at least a portion of the uplink control transmission and at least a portion of the uplink data transmission.
[0048] Specific embodiments of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some aspects, for situations where uplink control transmissions and uplink data transmissions overlap in time, sending both uplink control transmissions (such as PUCCH transmissions) and uplink data transmissions (such as PUSCH transmissions) on the same beam can improve spectrum utilization and spectrum efficiency. For example, the embodiments described herein can advantageously utilize resources by sharing resources at a dynamic level (such as across the time domain). In an example, for situations where the time domain overlaps, these embodiments can advantageously send at least a portion of the uplink control transmission (such as, sending hybrid automatic repeat request (HARQ) feedback, scheduling request (SR) or channel state information (CSI) report information) and at least a portion of the uplink data transmission on the same beam, rather than suppressing the transmission of the uplink control transmission. In some aspects, selecting between a beam associated with an uplink control transmission (such as a PUCCH transmission) and a beam associated with an uplink data transmission (such as a PUSCH transmission) can provide design flexibility. For example, a beam associated with uplink control transmissions (such as PUCCH transmissions) may be a relatively wide beam with higher reliability and connectivity, while a beam associated with uplink data transmissions (such as PUSCH transmissions) may be a relatively narrow beam providing higher bandwidth and increased throughput. Selecting between different beams can provide design flexibility with respect to reliability, connectivity, bandwidth, and throughput.
[0049] Figure 1 A diagram 100 of an example system for wireless communication supporting a quasi-co-location (QCL) assumption of simultaneous PUCCH and PUSCH is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.
[0050] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of varying forms or capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which a UE 115 and base station 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support communication of signals according to one or more radio access technologies.
[0051] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both stationary and mobile at different times. UEs 115 may be devices of different forms or capabilities. Figure 1 Some examples of UE 115 are shown in FIG. Figure 1 As shown, the UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (such as core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices).
[0052] The base stations 105 can communicate with the core network 130, or with each other, or with both the core network and the base station. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (such as, via S1, N2, N3, or another interface). The base stations 105 can communicate with each other directly (such as, directly between the base stations 105) or indirectly (such as, via the core network 130), or both, via the backhaul links 120 (such as, via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or can include one or more wireless links.
[0053] One or more of the base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or giga-NodeB (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology.
[0054] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various objects, such as appliances or vehicles, meters, and some other examples.
[0055] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples), such as Figure 1 shown.
[0056] The UE 115 and the base station 105 can communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of a radio frequency spectrum band (such as a bandwidth portion (BWP)) that operates according to one or more physical layer channels of a given radio access technology (such as LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (such as synchronization signals, system information), control signaling to coordinate carrier operation, user data, or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with the UE 115. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0057] Based on frequency / wavelength, the electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. In 5G NR, the two initial operating bands are identified by the frequency range names FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Sometimes, a similar naming issue arises regarding FR2, which is often (interchangeably) referred to as the millimeter wave band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU). With the above in mind, unless otherwise stated, it should be understood that the term "sub-6 GHz" and the like, if used herein, can broadly refer to frequencies less than 6 GHz, can be within FR1, or can include mid-band frequencies. Furthermore, unless otherwise stated, it should be understood that the term "millimeter wave" and the like, if used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.
[0058] In some examples (such as in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (such as an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode, where initial acquisition and connection may be performed by a UE 115 via the carrier, or in a non-standalone mode, where connections are anchored using different carriers (such as carriers of the same or different radio access technologies).
[0059] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (such as in an FDD mode) or may be configured to carry both downlink and uplink communications (such as in a TDD mode).
[0060] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (such as a base station 105, a UE 115, or both) may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (such as a subband, BWP) or all of the carrier bandwidth.
[0061] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may be composed of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate of the UE 115. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.
[0062] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, which can be referred to as T S =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can indicate the maximum supported subcarrier spacing, and N f The maximum supported Discrete Fourier Transform (DFT) size may be indicated. Time intervals for communication resources may be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0063] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (such as in the time domain), and each subframe may be further divided into a plurality of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a plurality of symbol periods (such as depending on the length of a cyclic prefix that is prepended to each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (such as, N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.
[0064] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).
[0065] Physical channels can be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels can be multiplexed on a downlink carrier using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search the control region for control information according to one or more search space sets, and each search space set can include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information of a control information format having a given payload size. A search space set can include a common search space set configured for sending control information to multiple UEs 115, and a UE-specific search space set for sending control information to a specific UE 115.
[0066] Each base station 105 can provide communication coverage via one or more cells, such as macro cells, small cells, hot spots, or other types of cells, or any combination thereof. The term "cell" can refer to a logical communication entity used to communicate with the base station 105 (such as via a carrier), and can be associated with an identifier (such as a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (such as a sector) on which the logical communication entity operates. Depending on various factors, such as the capabilities of the base station 105, these cells can range from smaller areas (such as structures, subsets of structures) to larger areas. For example, a cell can be or include a building, a subset of buildings, or an external space between or overlapping geographic coverage areas 110, etc.
[0067] A macro cell typically covers a relatively large geographic area (such as a radius of several kilometers) and may allow unrestricted access to UEs 115 that have a service subscription to a network provider that supports the macro cell. Small cells may be associated with base stations 105 that are relatively low-power compared to macro cells, and the small cells may operate in the same or different frequency bands (e.g., licensed, unlicensed) as the macro cells. Small cells may provide unrestricted access to UEs 115 that have a service subscription to a network provider, or may provide restricted access to UEs 115 associated with the small cell (such as UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also use one or more component carriers to support communications on one or more cells.
[0068] In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types that can provide access to different types of devices (such as MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)).
[0069] In some examples, base stations 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In some other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.
[0070] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably herein.
[0071] In some examples, UE 115 may also be able to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.
[0072] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (such as a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (such as a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entities may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be transmitted via user plane entities, which may provide IP address allocation and other functions. The user plane entities may be connected to network operator IP services 150. Network operator IP services 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.
[0073] Some of the network devices, such as base stations 105, may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices, such as radio heads and ANCs, or consolidated into a single network device, such as a base station 105.
[0074] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter wave band, because the wavelengths range in length from approximately 1 decimeter to 1 meter. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macrocell to provide service to a UE 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) than transmissions using the lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0075] The wireless communication system 100 can utilize licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in the unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operations in the unlicensed band can be based on a carrier aggregation configuration combined with component carriers (e.g., LAA) operating in the licensed band. Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as some other examples.
[0076] The base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.
[0077] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (such as a base station 105 or a UE 115) to shape or steer an antenna beam (such as a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating in a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (such as relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).
[0078] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beam forming operation. For example, the base station 105 may use multiple antennas or antenna arrays (such as antenna panels) to perform beam forming operations for directional communication with the UE 115. Some signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beam forming weights associated with different transmission directions. Transmissions in different beam directions may be used to identify (such as by a transmitting device such as the base station 105, or by a receiving device such as the UE 115) the beam direction for later transmission or reception by the base station 105.
[0079] Some signals, such as data signals associated with a particular receiving device, may be transmitted by base station 105 in a single beam direction, such as a direction associated with a receiving device such as UE 115. In some examples, a beam direction associated with a transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal that UE 115 received with the highest signal quality or an otherwise acceptable signal quality.
[0080] In some examples, transmissions by a device (such as a base station 105 or a UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (such as from the base station 105 to the UE 115). The UE 115 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to the number of configured beams across the system bandwidth or one or more subbands. The base station 105 can send a reference signal (such as a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which can be precoded or uncoded. The UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (such as a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques for sending signals multiple times in different directions (such as for identifying a beam direction for subsequent transmission or reception by UE 115), or for sending signals in a single direction (such as for sending data to a receiving device).
[0081] When receiving various signals from the base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals, a receiving device (such as a UE 115) may try multiple reception configurations (such as directional listening). For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array (such as different directional listening weight sets), or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which according to different reception configurations or reception directions may be referred to as "listening". In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (such as when receiving data signals). According to the different reception configuration directions, the single reception configuration may be aligned in a beam direction determined based on listening (such as a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).
[0082] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate over logical channels. The media access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between UE 115 and base station 105 or core network 130 that support radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.
[0083] UE 115 and base station 105 can support retransmission of data to increase the likelihood of successfully receiving the data. HARQ feedback is a technique for increasing the likelihood of correctly receiving data over communication link 125. HARQ may include a combination of error detection (such as using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (such as automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (such as low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, wherein the device may provide HARQ feedback in a particular time slot for data received in the previous symbol in the time slot. In other cases, the device may provide HARQ feedback in subsequent time slots or according to some other time interval.
[0084] The UE 115 may receive a configuration message indicating a first beam associated with an uplink control transmission (such as a PUCCH transmission). The UE 115 may receive a DCI including a grant for an uplink data transmission (such as a PUSCH transmission). The DCI may indicate a second beam associated with the uplink data transmission. In some examples, the beam indication may also be referred to as a transmission configuration indication (TCI) or a spatial relationship information (SRI) indication, where a reference signal such as a synchronization signal block (SSB), a CSI-RS, or a sounding reference signal (SRS) is provided. In some embodiments, the UE 115 may apply the same spatial filter or quasi-co-location (QCL) assumption as the reference signal to the uplink transmission. For example, the PUCCH may be configured in a beam indication (such as an indication of the first beam provided by the configuration message): a TCI state identifier for a reference signal with QCL type D, or spatial relationship information with an SRS resource identifier. In another example, a TCI code point mapped to a TCI state identifier of a reference signal with QCL type D, or an SRS resource indicator code point referenced to an SRS resource identifier may be indicated for the PUSCH in a beam indication (such as an indication of a second beam provided by a DCI). In one aspect, the UE 115 may select the first beam or the second beam to transmit both the uplink control transmission and the uplink data transmission based on a temporal overlap between the uplink control transmission and the uplink data transmission. In some aspects, the UE 115 may select the first beam or the second beam based on a set of rules or criteria. In an example, the UE 115 may select between the first beam and the second beam based on a first priority associated with the first beam and a second priority associated with the second beam. The priority associated with the beam may include a physical layer priority. The UE 115 may transmit at least a portion of the uplink control transmission and at least a portion of the uplink data transmission using the selected first beam or the second beam.
[0085] Figure 2 Schematic diagram 200 of an example system supporting QCL assumptions for simultaneous PUCCH and PUSCH is shown. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100 and may include UE 115-a and base station 105-a, which may be referenced as Figure 1 An example of a UE 115 and a base station 105 is described. The base station 105-a and the UE 115-a may use downlink communications 205 and uplink communications 210 and use reference Figure 1 The described technologies communicate with each other within the coverage area.
[0086] UE 115-a may receive a configuration message 215 from base station 105-a. The configuration message 215 may indicate a first beam associated with an uplink control transmission, such as PUCCH 230. For example, the configuration message 215 may indicate scheduling information associated with the uplink control transmission, such as PUCCH 230, and a beam associated with the uplink control transmission, such as the first beam. The uplink control transmission, such as PUCCH 230, may include HARQ feedback, SR, or CSI reporting information. In some aspects, UE 115-a may receive the configuration message 215 via RRC signaling. For example, the configuration message 215 may include an RRC message indicating the first beam associated with the uplink control transmission. In an example, the RRC message may indicate scheduling information associated with the uplink control transmission, such as PUCCH 230, and a beam associated with the uplink control transmission, such as the first beam. UE 115-a may receive DCI 220 from base station 105-a. DCI 220 may be a DCI message. DCI 220 may include a grant for uplink data transmission, such as PUSCH 235. In an example, DCI 220 may indicate a second beam associated with the uplink data transmission.
[0087] UE 115-a may determine overlap 240 (e.g., in the time domain) between an uplink control transmission, such as PUCCH 230, and an uplink data transmission, such as PUSCH 235. In some aspects, UE 115-a may determine overlap 240 based on scheduling information indicated in a configuration message 215 (e.g., an RRC message) for a first beam and scheduling information indicated in a DCI 220 for a second beam. For example, UE 115-a may determine overlap 240, e.g., where PUCCH 230 and PUSCH 235 are scheduled in the same serving cell and overlap in time. In some embodiments, UE 115-a may determine overlap 240 for a scenario where PUCCH 230 and PUSCH 235 are respectively scheduled in two different serving cells configured for intra-band carrier aggregation operation. UE 115-a may select the first beam or the second beam based on overlap 240 to transmit both an uplink control transmission (such as PUCCH 230) and an uplink data transmission (such as PUSCH 235). In some aspects, UE 115 may select the first beam or the second beam based on a set of rules or criteria associated with the first beam and the second beam. In an example, UE 115-a may select between the first beam and the second beam based on a first priority associated with the first beam and a second priority associated with the second beam. The priorities associated with the beams may include physical layer (PHY) priorities.
[0088] In an example, UE 115-a may select a first beam based on overlap 240 for transmitting both an uplink control transmission, such as PUCCH 230, and an uplink data transmission, such as PUSCH 235. In another example, UE 115-a may select a second beam based on overlap 240 for transmitting both an uplink control transmission, such as PUCCH 230, and an uplink data transmission, such as PUSCH 235. UE 115-a may use the selected beam, such as the selected first beam or the second beam, to transmit uplink communication 210. For example, UE 115-a may use the selected beam to transmit at least a portion of the uplink control transmission, as well as at least a portion of the uplink control transmission, such as PUCCH 230, and an uplink data transmission, such as PUSCH 235. In some examples, UE 115-a may use the selected beam to transmit all of an uplink control transmission, such as PUCCH 230, and all of an uplink data transmission, such as PUSCH 235. In some other examples, UE 115-a may use the selected beam to transmit overlapping portions of an uplink control transmission, such as PUCCH 230, and overlapping portions of an uplink data transmission, such as PUSCH 235.
[0089] When sending an uplink control transmission (such as PUCCH 230) and an uplink data transmission (such as PUSCH 235) using the selected beam, UE 115-a may multiplex at least the overlapping portion of the uplink control transmission (such as PUCCH 230) and the uplink data transmission (such as PUSCH 235). The uplink control transmission (such as PUCCH 230) sent on the selected beam may include HARQ feedback and CSI reporting information. In some aspects, UE 115-a may separately send an uplink control transmission (such as PUCCH 230) and an uplink data transmission (such as PUSCH 235) using different serving cells (such as component carriers configured by configuration message 215 and DCI 220).
[0090] In another aspect, UE 115-a may use the same serving cell (e.g., component carrier) to send uplink control transmissions (such as PUCCH 230) and uplink data transmissions (such as PUSCH 235). For example, the uplink control transmissions (such as PUCCH 230) and uplink data transmissions (such as PUSCH 235) may overlap in the time domain using different resources of the serving cell. In another example, UE 115-a may multiplex uplink control transmissions (such as PUCCH 230) and uplink data transmissions (such as PUSCH 235) in the frequency domain (such as, frequency division multiplexing). In some other aspects, UE 115-a may use different intra-band serving cells (such as, intra-band component carriers) associated with intra-band carrier aggregation to separately send uplink control transmissions (such as PUCCH 230) and uplink data transmissions (such as PUSCH 235).
[0091] For situations where an uplink control transmission (such as PUCCH 230) and an uplink data transmission (such as PUSCH 235) at least partially overlap in time, the example aspects described herein may be advantageous over some wireless communication systems that do not support sending both an uplink control transmission (such as PUCCH 230) and an uplink data transmission (such as PUSCH 235) on the same beam. For example, in situations where an uplink control transmission (such as PUCCH 230) including HARQ feedback, SR, or CSI reporting information and an uplink data transmission (such as PUSCH 235) overlap (such as in the time domain), some UEs may transmit the uplink data transmission (such as PUSCH 235) and refrain from transmitting the uplink control transmission (such as PUCCH 230). For example, in some embodiments, some UEs may include HARQ feedback, SR, or CSI reporting information in an uplink data transmission (such as PUSCH 235).
[0092] Thus, compared to other wireless communication systems that refrain from sending uplink control transmissions (such as, PUCCH 230), in situations where uplink control transmissions (such as, PUCCH 230) and uplink data transmissions (such as, PUSCH 235) overlap, the example aspects described herein can improve spectrum utilization and spectrum efficiency, advantageously utilizing resources to send both uplink control transmissions (such as, PUCCH 230) and uplink data transmissions (such as, PUSCH 235).
[0093] Figure 3An example block diagram 300 is shown for a QCL assumption supporting simultaneous PUCCH and PUSCH. Example 300 may implement aspects of wireless communication systems 100 or 200. PUCCH 315 may be a reference Figure 2 Examples of uplink control transmissions such as PUCCH 230 are described. PUSCH 310-a and PUSCH 310-b may be referenced. Figure 2 An example of uplink data transmission (such as PUSCH 235) is described. Additionally, DCI 305-a and DCI 305-b may be referenced. Figure 2 An example of DCI 220 is described.
[0094] refer to Figure 2 , UE 115-a may be configured to transmit using a single antenna panel of UE 115-a for simultaneous transmission of uplink control transmissions (i.e., PUCCH 315) and uplink data transmissions (e.g., PUSCH 310-a) that overlap (e.g., in the time domain, as shown by overlap 320). In some aspects, simultaneous transmission of uplink control transmissions (i.e., PUCCH 315) and uplink data transmissions (e.g., PUSCH 310-a) using the same serving cell (e.g., component carrier) may be achieved. In some other aspects, simultaneous transmission of uplink control transmissions (i.e., PUCCH 315) and uplink data transmissions (e.g., PUSCH 310-a) using different intra-band serving cells (e.g., intra-band component carriers) associated with intra-band carrier aggregation (CA) may be achieved.
[0095] UE 115-a may receive a configuration message (such as an RRC message) from base station 105-a. The configuration message may indicate a first beam associated with an uplink control transmission (such as PUCCH 315). Additionally, UE 115-a may receive DCI 305-a (such as a DCI message) from base station 105-a. DCI 305-a may include a grant for an uplink data transmission (such as PUSCH 310-a). In an example, DCI 305-a may indicate a second beam associated with an uplink data transmission (such as PUSCH 310-a).
[0096] UE 115-a may select a first beam associated with an uplink control transmission (such as, PUCCH 315) or a second beam associated with an uplink data transmission (such as, PUSCH 310-a) for transmitting both the uplink control transmission (such as, PUCCH 315) and the uplink data transmission (such as, PUSCH 310-a). In an example, UE 115-a may select the first beam associated with the uplink control transmission (such as, PUCCH 315) or the second beam associated with the uplink data transmission (such as, PUSCH 310-a) based on a first priority associated with the first beam and a second priority associated with the second beam. For example, UE 115-a may determine that the first priority associated with the first beam is greater than the second priority associated with the second beam, and UE 115-a may select the first beam associated with the uplink control transmission (such as, PUCCH 315) based on the higher priority of the first beam. For example, UE 115 - a may determine that the first priority is a higher priority among the priorities based on an association between the first beam and an uplink control transmission, such as PUCCH 315 .
[0097] In some aspects, UE 115-a may select a first beam associated with an uplink control transmission, such as PUCCH 315, for use in transmitting both the uplink control transmission, such as PUCCH 315, and an uplink data transmission, such as PUSCH 310-a. UE 115-a may transmit at least an overlapping portion of the uplink control transmission, such as PUCCH 315, and the uplink data transmission, such as PUSCH 310-a, to base station 105-a using the selected first beam. Thus, for uplink control transmissions (such as, PUCCH 315) and uplink data transmissions (such as, PUSCH 310-a) that overlap (such as, in the time domain), UE 115-a may schedule the transmission of both the uplink control transmission (such as, PUCCH 315) and the uplink data transmission (such as, PUSCH 310-a) on the antenna panel of UE 115-a using the beam associated with sending the uplink control transmission (such as, PUCCH 315).
[0098] In another aspect, UE 115-a may select a second beam associated with an uplink data transmission (such as PUSCH 310-a) for use in transmitting both an uplink control transmission (such as PUCCH 315) and an uplink data transmission (such as PUSCH 310-a). For example, a first beam used to transmit an uplink control transmission (such as PUCCH 315) is overridden by a second beam used to transmit an uplink data transmission (such as PUSCH 310-a). UE 115-a may transmit at least an overlapping portion of the uplink control transmission (such as PUCCH 315) and the uplink data transmission (such as PUSCH 310-a) to base station 105-a using the selected second beam. Thus, for uplink control transmissions (such as, PUCCH 315) and uplink data transmissions (such as, PUSCH 310-a) that overlap (such as, in the time domain), UE 115-a may schedule the transmission of both the uplink control transmission (such as, PUCCH 315) and the uplink data transmission (such as, PUSCH 310-a) on the antenna panel of UE 115-a using the beam associated with sending the uplink data transmission (such as, PUSCH 310-a).
[0099] In some other aspects, UE 115-a may determine that the second beam indicated in DCI 305-a, such as the second beam associated with an uplink data transmission, such as PUSCH 310-a, is the same as the first beam indicated in the configuration message, such as the first beam associated with an uplink control transmission, such as PUCCH 315. Accordingly, UE 115-a may schedule transmission of both an uplink control transmission, such as PUCCH 315, and an uplink data transmission, such as PUSCH 310-a, based on determining that the first beam and the second beam are the same, such as using a common beam.
[0100] Figure 4 An example block diagram 400 is shown for a QCL assumption supporting simultaneous PUCCH and PUSCH. Example 400 may implement aspects of wireless communication system 100 or 200 or example 300. PUCCH 415-a and PUCCH 415-b may be reference Figure 2 Examples of uplink control transmissions (e.g., PUCCH 240) are described. PUSCH 410-a and PUSCH 410-b may be referenced. Figure 2 An example of uplink data transmission (e.g., PUSCH 245) is described. Additionally, DCI 405-a and DCI 405-b may be referenced. Figure 2An example of DCI 220 is described.
[0101] refer to Figure 2 , UE 115-a may be configured to transmit using a single antenna panel of UE 115-a for simultaneous transmission of uplink control transmissions (such as PUCCH 415-a, PUCCH 415-b) and uplink data transmissions (such as PUSCH 410-a, PUSCH 410-b) that overlap (e.g., in the time domain, as shown by overlap 420 and overlap 425). In some aspects, simultaneous transmission of uplink control transmissions (such as PUCCH 415-a, PUCCH 415-b) and uplink data transmissions (such as PUSCH 410-a, PUSCH 410-b) using the same serving cell (e.g., component carrier) may be achieved. In some other aspects, simultaneous transmission of uplink control transmissions (such as, PUCCH 415-a, PUCCH 415-b) and uplink data transmissions (such as, PUSCH 410-a, PUSCH 410-b) using different intra-band serving cells (e.g., intra-band component carriers) associated with intra-band carrier aggregation can be achieved.
[0102] UE 115-a may receive a configuration message (such as an RRC message) from base station 105-a. The configuration message may indicate a first beam associated with an uplink control transmission (such as PUCCH 415-a). Additionally, UE 115-a may receive DCI 405-a (such as a DCI message) from base station 105-a. DCI 405-a may include an authorization for an uplink data transmission (such as PUSCH 410-a). In an example, DCI 405-a may indicate a second beam associated with an uplink data transmission (such as PUSCH 410-a). In some aspects, the configuration message may indicate a beam associated with another uplink control transmission (such as PUCCH 415-b), and UE 115-a may receive DCI 405-b (such as a DCI message) including an authorization for the other uplink data transmission (such as PUSCH 410-b).
[0103] UE 115-a may receive an indication of a first priority associated with a first beam that is associated with an uplink control transmission, such as PUCCH 415-a. UE 115-a may receive an indication of a second priority associated with a second beam that is associated with an uplink data transmission, such as PUSCH 410-a. In some aspects, the first priority associated with the first beam and the second priority associated with the second beam may comprise a physical layer priority. The priorities may indicate, for example, whether the first beam and the second beam are each associated with a high priority service, such as ultra-reliable low-latency communication (URLLC), or with a lower priority service, such as enhanced mobile broadband (eMBB). For example, the value of the priority may be 0 or 1. In an example, a priority value of 1 may be employed to indicate a URLLC service, and a priority value of 0 may be employed to indicate an eMBB service.
[0104] In some aspects, UE 115-a may select the first beam or the second beam based on a difference between a first priority associated with the first beam and a second priority associated with the second beam. For example, a first beam associated with an uplink control transmission (such as, PUCCH 415-a) may have a relatively lower physical layer priority (such as, PHY=0), while a second beam associated with an uplink data transmission (such as, PUSCH 410-a) may have a relatively higher physical layer priority (such as, PHY=1). In an example, UE 115-a may select the second beam associated with an uplink data transmission (such as, PUSCH 410-a) based on the higher physical layer priority.
[0105] Thus, for uplink control transmissions (such as, PUCCH 415-a) and uplink data transmissions (such as, PUSCH 410-a) that overlap (such as, in the time domain), UE 115-a may schedule the transmission of both the uplink control transmission (such as, PUCCH 415-a) and the uplink data transmission (such as, PUSCH 410-a) on the antenna panel of UE 115-a using a beam with a higher physical layer priority (such as, a second beam associated with transmitting the uplink data transmission (such as, PUSCH 410-a)).

Certain operations may also be omitted from process flow 500, or other operations may be added to process flow 500. It should be understood that although base station 105-b and UE 115-b are shown performing many of the operations of process flow 500, any wireless device may perform the operations shown.
[0108] At 505, UE 115-b may receive a configuration message indicating a first beam associated with an uplink control transmission, such as a PUCCH transmission. In some aspects, the configuration message may include an RRC message.
[0109] At 510, UE 115-b may receive a DCI including a grant for an uplink data transmission, such as a PUSCH transmission. In some aspects, the DCI may indicate a second beam associated with the uplink data transmission.
[0110] At 515, UE 115-b may select the first beam or the second beam for transmitting both the uplink control transmission and the uplink data transmission based on the temporal overlap between the uplink control transmission and the uplink data transmission. In some aspects, UE 115-b may select the first beam or the second beam for transmitting both the uplink control transmission and the uplink data transmission based on a first priority associated with the first beam and a second priority associated with the second beam.
[0111] At 520, the base station 105-b may identify a first beam or a second beam for UE transmission of both the uplink control transmission and the uplink data transmission to the base station based on a temporal overlap between the uplink control transmission and the uplink data transmission. In some aspects, the base station 105-b may identify the first beam or the second beam for transmitting both the uplink control transmission and the uplink data transmission based on a first priority associated with the first beam and a second priority associated with the second beam.
[0112] At 525, UE 115-b may send at least a portion of an uplink control transmission and at least a portion of an uplink data transmission using the selected first beam or second beam.

For example, the communication manager 910 can obtain from the transceiver 920 a configuration message indicating a first beam associated with an uplink control transmission, a DCI including a grant for uplink data transmission (the DCI indicating a second beam associated with the uplink data transmission), or both.

The transceiver 920 can also include a modem to modulate packets and provide the modulated packets to the antenna for transmission, and demodulate packets received from the antenna.
[0147] In some embodiments, a wireless device may include a single antenna 925. However, in some embodiments, a device may have more than one antenna 925, which may be capable of concurrently sending or receiving multiple wireless transmissions.
[0148] The memory 930 may include random access memory (RAM) and read-only memory (ROM). In some embodiments, the memory 930 may include BIOS, etc., which may control basic hardware or software operations, such as interaction with peripheral components or devices.
[0149] The processor 940 may include an intelligent hardware device (such as a general-purpose processor, a DSP, a CPU, a microcontroller, an ASIC, an FPGA, a programmable logic device, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some embodiments, the processor 940 may be configured to operate the memory array using a memory controller. In other cases, the memory controller may be integrated into the processor 940.

[0151] In some embodiments, controller / processor 940 may be a component of a processing system. A processing system may generally refer to a system or series of machines or components that receives input and processes the input to produce a set of outputs that may be delivered to other systems or components, such as device 905. For example, the processing system of device 905 may refer to a system that includes various other components or subcomponents of device 905.
[0152] The processing system of device 905 can interface with other components of device 905 and can process information (such as input or signal) received from other components, output information to other components, etc. For example, the chip or modem of device 905 may include a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending or providing information. In some embodiments, the first interface may refer to an interface between the processing system and a receiver of the chip or modem, so that the device 905 can receive information or signal input, and the information can be passed to the processing system. In some embodiments, the second interface may refer to an interface between the processing system and a transmitter of the chip or modem, so that the device 905 can send information output from the chip or modem. It will be readily appreciated by those skilled in the art that the second interface may also obtain or receive information or signal input, and the first interface may also output, send or provide information.

In some embodiments, the processor 1340 may be configured to operate the memory array using a memory controller. In some embodiments, the memory controller may be integrated into the processor 1340.
[0190] The inter-site communication manager 1345 can manage communications with other base stations 105 and can include a controller or scheduler for controlling communications with the UE 115 in cooperation with the other base stations 105. For example, the inter-site communication manager 1345 can coordinate the scheduling of transmissions to the UE 115 for various interference mitigation techniques such as beamforming or joint transmission.

[0192] In some embodiments, controller / processor 1340 may be a component of a processing system. A processing system may generally refer to a system or series of machines or components that receives input and processes the input to produce a set of outputs that may be delivered to other systems or components, such as device 1305. For example, the processing system of device 1305 may refer to a system that includes various other components or subcomponents of device 1305.
[0193] The processing system of device 1305 can interface with other components of device 1305 and can process information (such as input or signals) received from other components, output information to other components, etc. For example, the chip or modem of device 1305 may include a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some embodiments, the first interface may refer to an interface between the processing system of the chip or modem and a receiver, so that the device 1305 can receive information or signal input and the information can be passed to the processing system. In some embodiments, the second interface may refer to an interface between the processing system of the chip or modem and a transmitter, so that the device 1305 can send information output from the chip or modem. It will be readily appreciated by those skilled in the art that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.
