Title: Split uplink control information for full-duplex communications

Description:
FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for split uplink control information (UCI) for full-duplex communications. 
     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, and/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 communication network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, and/or the like. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New Radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (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 (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

     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. Based on the teachings herein 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, and/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. 
     It should be noted that while aspects may be described herein using terminology commonly associated with 3G and/or 4G wireless technologies, aspects of the present disclosure can be applied in other generation-based communication systems, such as 5G and later, including NR technologies. 
       FIG. 1  is a diagram illustrating a wireless network  100  in which aspects of the present disclosure may be practiced. The wireless network  100  may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network  100  may include a number of BSs  110  (shown as BS  110   a , BS  110   b , BS  110   c , and BS  110   d ) and other network entities. A BS is an entity that communicates with user equipment (UEs) and may also be referred to as a base station, a NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and/or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used. 
     A BS 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 with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in  FIG. 1 , a BS  110   a  may be a macro BS for a macro cell  102   a , a BS  110   b  may be a pico BS for a pico cell  102   b , and a BS  110   c  may be a femto BS for a femto cell  102   c . A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein. 
     In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces such as a direct physical connection, a virtual network, and/or the like using any suitable transport network. 
     Wireless network  100  may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in  FIG. 1 , a relay station  110   d  may communicate with macro BS  110   a  and a UE  120   d  in order to facilitate communication between BS  110   a  and UE  120   d . A relay station may also be referred to as a relay BS, a relay base station, a relay, and/or the like. 
     Wireless network  100  may be a heterogeneous network that includes BSs of different types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network  100 . For example, macro BSs may have a high transmit power level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 Watts). 
     A network controller  130  may couple to a set of BSs and may provide coordination and control for these BSs. Network controller  130  may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul. 
     UEs  120  (e.g.,  120   a ,  120   b ,  120   c ) may be dispersed throughout wireless network  100 , and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE 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 or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium. 
     Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, and/or the like, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE  120  may be included inside a housing that houses components of UE  120 , such as processor components, memory components, and/or the like. 
     In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, and/or the like. A frequency may also be referred to as a carrier, a frequency channel, and/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 aspects, 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, and/or the like), a mesh network, and/or the like. In this case, the UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     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  shows a block diagram of a design  200  of base station  110  and UE  120 , which may be one of the base stations and one of the UEs in  FIG. 1 . Base station  110  may be equipped with T antennas  234   a  through  234   t , and UE  120  may be equipped with R antennas  252   a  through  252   r , where in general T≥1 and R≥1. 
     At base station  110 , a transmit processor  220  may receive data from a data source  212  for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor  220  may also process system information (e.g., for semi-static resource partitioning information (SRPI) and/or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and/or the like) and provide overhead symbols and control symbols. Transmit processor  220  may also generate reference symbols for reference signals (e.g., the cell-specific reference signal (CRS)) and synchronization signals (e.g., the primary synchronization signal (PSS) and 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 T output symbol streams to T modulators (MODs)  232   a  through  232   t . Each modulator  232  may process a respective output symbol stream (e.g., for OFDM and/or the like) to obtain an output sample stream. Each modulator  232  may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators  232   a  through  232   t  may be transmitted via T antennas  234   a  through  234   t , respectively. According to various aspects described in more detail below, the synchronization signals can be generated with location encoding to convey additional information. 
     At UE  120 , antennas  252   a  through  252   r  may receive the downlink signals from base station  110  and/or other base stations and may provide received signals to demodulators (DEMODs)  254   a  through  254   r , respectively. Each demodulator  254  may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator  254  may further process the input samples (e.g., for OFDM and/or the like) to obtain received symbols. A MIMO detector  256  may obtain received symbols from all R demodulators  254   a  through  254   r , perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE  120  to a data sink  260 , and provide decoded control information and system information to a controller/processor  280 . A channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), and/or the like. In some aspects, one or more components of UE  120  may be included in a housing. 
     On the uplink, at UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor  280 . Transmit processor  264  may also generate reference symbols for one or more reference signals. The symbols from transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by modulators  254   a  through  254   r  (e.g., for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to base station  110 . At base station  110 , the uplink signals from UE  120  and other UEs may be received by antennas  234 , processed by demodulators  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 UE  120 . Receive processor  238  may provide the decoded data to a data sink  239  and the decoded control information to controller/processor  240 . Base station  110  may include communication unit  244  and communicate to network controller  130  via communication unit  244 . Network controller  130  may include communication unit  294 , controller/processor  290 , and memory  292 . 
     Controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG. 2  may perform one or more techniques associated with split UCI for full-duplex (FD) communications, as described in more detail elsewhere herein. For example, controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG. 2  may perform or direct operations of, for example, process  600  of  FIG. 6 , process  700  of  FIG. 7 , and/or other processes as described herein. Memories  242  and  282  may store data and program codes for base station  110  and UE  120 , respectively. In some aspects, memory  242  and/or memory  282  may comprise a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station  110  and/or the UE  120 , may perform or direction operations of, for example, process  600  of  FIG. 6 , process  700  of  FIG. 7 , and/or other processes as described herein. A scheduler  246  may schedule UEs for data transmission on the downlink and/or uplink. 
     In some aspects, UE  120  may include means for receiving configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone; means for transmitting uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information; means for selecting a resource for the uplink control channel based at least in part on the resource pattern or the set of resource patterns; and/or the like. In some aspects, such means may include one or more components of UE  120  described in connection with  FIG. 2 , such as controller/processor  280 , transmit processor  264 , TX MIMO processor  266 , MOD  254 , antenna  252 , DEMOD  254 , MIMO detector  256 , receive processor  258 , and/or the like. 
     In some aspects, base station  110  may include means for transmitting configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone; means for receiving uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information; means for triggering retransmission of the first UCI based at least in part on the first UCI being received in the non-FD zone; means for receiving the first UCI and the second UCI; means for combining the first UCI and the second UCI to generate the UCI; means for demodulating the first UCI and not the second UCI based at least in part on the first UCI being received in the non-FD zone and the second UCI being received in the FD zone; and/or the like. In some aspects, such means may include one or more components of base station  110  described in connection with  FIG. 2 , such as antenna  234 , DEMOD  232 , MIMO detector  236 , receive processor  238 , controller/processor  240 , transmit processor  220 , TX MIMO processor  230 , MOD  232 , antenna  234 , and/or the like. 
     As indicated above,  FIG. 2  is provided as an example. Other examples may differ from what is described with regard to  FIG. 2 . 
     A UE may provide information on the uplink (UL) using UL control information (UCI). UCI may include, for example, channel state information (CSI), a scheduling request (SR), a hybrid automatic repeat request (HARQ) acknowledgment (ACK) or negative ACK (HACK), and/or the like, which may be referred to as UCI types. The UCI may be transmitted on a physical uplink control channel (PUCCH). Different UCI types may be associated with different priority levels. For example, a HARQ ACK/NACK may have a highest priority level, followed by an SR, and followed by CSI. CSI may have a higher sub-priority level and a lower sub-priority level. There may be different formats of PUCCH, such as a short PUCCH (e.g., Format 0, Format 2, and/or the like), a long PUCCH (e.g., Format 1, Format 3, Format 4, and/or the like), and/or the like. A UE may not transmit more than one PUCCH with HARQ-ACK information in a slot. When the UE transmits two PUCCHs in a slot, at least one of the two PUCCHs uses PUCCH Format 0 or PUCCH Format 2. 
     PUCCH Format 0 may include 1 or 2 symbols, may use sequence based transmission, may not use UCI and demodulation reference signal (DMRS) multiplexing, and may use coherent detection. PUCCH Format 2 may include 1 or 2 symbols, and may use UCI and DMRS frequency-division multiplexing A long PUCCH may use UCI and DMRS time-division multiplexing. In some aspects, multiple DMRS symbols may be transmitted in a single PUCCH transmission (e.g., a single hop). For example, 2 DMRS symbols may be transmitted per hop of a PUCCH Format 3 or 4 if both hops are more than X symbols when frequency hopping is enabled (X=4). 4 DMRS symbols may be transmitted for a PUCCH Format 3 or 4 with more than 2X+1 symbols when frequency hopping is disabled (X=4). 
     A wireless communication device may utilize full-duplex (FD) communication to increase link capacity and more efficiently utilize frequency and time resources. FD communication is described in more detail with regard to  FIG. 3 . However, FD communication may cause more interference in an FD zone (e.g., a time and/or frequency region in which FD communication occurs) than in a non-FD zone (e.g., a time and/or frequency region in which FD communication does not occur). Accordingly, UCI performance in the FD region may be worse than UCI performance in the non-FD region. This may be particularly problematic when UCI is transmitted by a UE and thus has low transmit power relative to BS transmissions. Furthermore, different UCI types are associated with different priority levels, so the transmission of a high-priority UCI in an FD zone (where interference is high) and/or a low-priority UCI in a non-FD zone (where interference is lower than in the FD zone) may be an inefficient utilization of network resources. 
     Some techniques and apparatuses described herein provide resource allocation for the transmission of UCI in FD zones and/or non-FD zones. For example, some techniques and apparatuses described herein cause high-priority UCI to be allocated to a non-FD zone in which interference is lower, and low-priority UCI to be allocated to an FD zone in which interference is higher. Furthermore, some techniques and apparatuses described herein provide signaling and/or configuration to support this resource allocation technique. Thus, the priority levels of the UCI may be preserved while more efficiently allocating FD-zone and non-FD zone resources. 
       FIG. 3  is a diagram illustrating an example  300  of an FD zone, a non-FD zone, and self-interference associated with FD communications, in accordance with various aspects of the present disclosure. As shown, example  300  includes a BS (e.g., BS  110  and/or the like), a UE1 (e.g., UE  120  and/or the like), and a UE2 (e.g., UE  120  and/or the like). In some aspects, the BS may be capable of FD communication. FD communication may include a contemporaneous uplink and downlink communication using the same resources. For example, the BS may perform a downlink (DL) transmission to a UE1 (shown by reference number  310 ) and may receive an uplink (UL) transmission from a UE2 (shown by reference number  320 ) using the same frequency resources and at least partially overlapping in time. 
     As shown by reference number  330 , the DL transmission from the BS may self-interfere with the UL transmission to the BS. This may be caused by a variety of factors, such as the higher transmit power of the DL transmission, radio frequency bleeding, and/or the like. Furthermore, as shown by reference number  340 , the UL transmission to the BS from the UE2 may interfere with the DL transmission from the BS to the UE1, thereby diminishing DL performance of the UE1. 
     An FD zone is shown by reference number  350  and a non-FD zone is shown by reference number  360 . As used herein, an FD zone refers to a time period and/or a frequency region in which a wireless communication device (e.g., a BS  110 , a UE  120 , a node, a wireless communication device, and/or the like) performs FD communication, and a non-FD zone refers to a time period and/or a frequency region in which a wireless communication device performs non-FD communication. The FD zone may be associated with higher self-interference, and therefore a lower signal-to-interference-plus-noise ratio (SINR), than the non-FD zone. Techniques and apparatuses described herein provide for the splitting of uplink control information (UCI) between an FD zone and a non-FD zone (or for allocation of the UCI to the non-FD zone) to improve the performance of the UCI and improve conformance with UCI quality of service requirements. 
     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 splitting UCI for FD communications, in accordance with various aspects of the present disclosure. As shown, example  400  includes a BS  110  and a UE  120 . The BS  110  may be capable of FD communication with the UE  120  and/or other UEs  120  covered by the BS  110 . 
     As shown by reference number  410 , the BS  110  may provide configuration information to the UE  120 . The BS  110  may provide the configuration information using any messaging type, such as radio resource control (RRC) signaling, downlink control information, a media access control (MAC) control element (CE), high-layer configuration information, and/or the like. The configuration information may indicate how UCI, to be transmitted by the UE  120 , is to be allocated to one or more of a non-FD zone or an FD zone, as described in more detail below. 
     As shown, the configuration information may include a first resource identifier, shown as a first PUCCH resource identifier. The first resource identifier may be associated with the non-FD zone. For example, the first resource identifier may indicate a resource allocation of the non-FD zone, a resource set of the non-FD zone, and/or the like. In some aspects, the BS  110  may provide only the first resource identifier. If the BS  110  provides only the first resource identifier (e.g., if only the first resource identifier and not the second resource identifier is configured), then the UE  120  may use only the non-FD zone for transmission of UCI. For example, the BS  110  may determine that the non-FD zone is sufficient for the UCI payload, and may accordingly configure only the non-FD zone for the uplink control channel transmission. 
     In some aspects, the first resource identifier may explicitly identify a single parameter (e.g., a resource index to indicate which resource is to be used for the non-FD transmission and/or the like). This may conserve signaling resources that would otherwise be used to signal configuration information for multiple resource locations. In some aspects, the first resource identifier may identify a parameter using an index, such as an index corresponding to a particular resource location of multiple configured resource locations. This may conserve signaling resources that would otherwise be used to signal an explicit indication of the resource location, which may be more resource-intensive than signaling an index. 
     As shown, the configuration information may include a second resource identifier, shown as a second PUCCH resource identifier. The second resource identifier may be associated with the FD zone. For example, the second resource identifier may indicate a resource allocation of the FD-zone, a resource set of the FD zone, and/or the like. 
     In some aspects, a frame structure of the UE  120  and/or an FD configuration of the UE  120  may be semi-persistent or periodic. In such a case, the distribution of FD zones and non-FD zones, or of UCI transmissions in the FD zones and the non-FD zones, may follow one or more patterns. In some aspects, the second resource identifier may be provided using RRC signaling. For example, the second resource identifier may include an RRC value that identifies a particular pattern. Based at least in part on the UCI payload to be transmitted by the UE  120 , or an indication received from the BS  110  in downlink control information (DCI), the UE  120  may transmit the UCI in the FD zone and/or the non-FD zone. In some aspects, the second resource identifier may be provided as DCI. For example, the second resource identifier may identify a pattern from a plurality of configured patterns. In such a case, the second resource identifier may include an index corresponding to the pattern, an index corresponding to a set of patterns (e.g., from which the UE  120  may select a pattern for transmission of the UCI), an index corresponding to particular resource allocation patterns for the FD zone, and/or the like. 
     In some aspects, the frame structure of the UE  120  and/or the FD configuration of the UE  120  may be random, may be pseudorandom, or may not be configured in accordance with a pattern. In such a case, the second resource identifier may include a parameter (e.g., an index, such as a resource index and/or the like) that identifies a resource allocation, an index of a set of parameters to be used to determine the resource allocation, and/or the like. 
     In some aspects, the UE  120  may receive an indication of whether the UE  120  is to receive the second resource identifier. For example, the UE  120  may receive information indicating whether the second resource identifier is configured. This information may be provided using, for example, DCI, RRC signaling, and/or the like. This may reduce processing load at the UE  120  that would otherwise be used to dynamically detect the second resource identifier. In some aspects, the UE  120  may dynamically detect the second resource identifier. For example, the UE  120  may detect whether the BS  110  transmits the second resource identifier irrespective of whether an indicator is received (e.g., using blind decoding or a similar approach), which may reduce signaling resource consumption of the BS  110 . 
     As shown by reference number  420 , the UE  120  may determine an allocation of UCI into at least one of the FD zone or the non-FD zone in accordance with the configuration information. For example, the UE  120  may determine the allocation of CSI, an ACK/NACK, a scheduling request, and/or the like into one or more of the FD zone or the non-FD zone. In some aspects, the UE  120  may determine the allocation of the UCI based at least in part on an indication received from the BS  110 . In some aspects, the UE  120  may determine allocation based at least in part on a priority rule. Each is described in turn below. When a first part of the UCI is allocated to the non-FD zone and a second part of the UCI is allocated to the FD zone, the UCI may be said to be split between the non-FD zone and the FD zone. 
     In some aspects, a rule or table may indicate which UCI is to be transmitted in the FD zone. For example, the rule or table may include a predefined rule, a predefined table, and/or the like. In some aspects, the rule or table may be configured using RRC signaling. For example, the BS  110  may configure which UCI should be transmitted in the FD zone (e.g., the rule may indicate that only CSI is to be transmitted in the FD zone). 
     In some aspects, the BS  110  may indicate which UCI is to be transmitted in the FD zone. For example, the BS  110  may provide DCI, RRC signaling, and/or the like that indicates which CSI is to be transmitted in the FD zone. In some aspects, such an indication may correspond to a particular slot, a particular UE  120 , a particular location, and/or the like. In some aspects, the indication of which UCI is to be transmitted in the FD zone may be configurable, dynamic or flexible (e.g., may be configured using RRC, may be dynamically indicated using DCI, or may be indicated from a plurality of possible values). As an example of dynamic indication, when FD and non-FD zones are configured, and when ACK/NACK, SR, and CSI are multiplexed for the PUCCH, the BS  110  may indicate that CSI is to be transmitted in the FD zone, and the ACK/NACK and the SR are to be transmitted in the non-FD zone. As another example, the BS  110  may indicate that CSI and SR are to be transmitted in the FD zone, and the ACK/NACK is to be transmitted in the non-FD zone. 
     In some aspects, the UCI in the FD zone may be a repetition of the UCI in the non-FD zone. This may improve reception of the UCI by the BS  110 , as described below. In some aspects, different portions of the UCI may use different PUCCH formats, based at least in part on the UCI type of the UCI and a configured PUCCH symbol length. For example, for a non-FD zone with a 2-symbol UCI length, the UE  120  may use a short PUCCH format (e.g., Format 0) to perform an ACK/NACK transmission. 
     In some aspects, when the second resource identifier is not configured, the BS  110  may configure the non-FD zone for a transmission by performing rate-matching, which may conserve signaling resources that would otherwise be used to configure transmission of the CSI in the FD zone and the non-FD zone. 
     As shown by reference number  430 , the UE  120  may transmit the UCI in the FD zone and/or the non-FD zone. For example, when only the first resource identifier is received, the UE  120  may transmit the UCI in only the non-FD zone. When the first resource identifier and the second resource identifier are received, the UE  120  may transmit a first part of the UCI (e.g., a higher-priority part) in the non-FD zone, and may transmit a second part of the UCI (e.g., a lower-priority part) in the FD zone. Thus, reliability of UCI is improved. 
     In some aspects, the CSI in the FD zone and the CSI in the non-FD zone may be associated with different power control parameters. For example, a transmission in the FD zone may use a modified transmit power relative to a transmission in the non-FD zone. In some aspects, the FD zone and the non-FD zone may use independent power control parameters (e.g., independent from each other). In some aspects, the FD zone may use a fixed power boosting ratio relative to the non-FD zone. For example, a power for the FD zone, denoted as P_FD, may be defined relative to a power for the non-FD zone, denoted as P_NFD, using a power boosting ratio of beta: 
         P _ FD =beta* P _ NFD.    
     In some aspects, the FD zone and the non-FD zone may use different power boosting parameters than a baseline physical uplink shared channel (PUSCH) power level. For example, where P denotes the PUSCH power level: 
         P _ FD =beta_1* P, P _ NFD =beta_2* P.    
     As shown by reference number  440 , the BS  110  may receive the UCI in the FD zone and/or the non-FD zone. In some aspects, the BS  110  may demodulate or receive only the UCI in the non-FD zone. In such a case, the BS  110  may discard the FD-zone portions of the UCI (since the FD-zone portions of the UCI may be associated with a low reliability). In some aspects, the BS  110  may trigger repetition or retransmission of only the FD zone portion of the UCI in a next UL transmission. In some aspects, the BS  110  may trigger repetition or retransmission of the non-FD zone portion of the UCI in a next UL transmission. Thus, the BS  110  may conserve resources that would otherwise be used to attempt to decode an FD-zone UCI transmission with a low likelihood of success. 
     In some aspects, the BS  110  may receive the UCI in the non-FD zone and the UCI in the FD zone. In such a case, the BS  110  may combine the UCI from the non-FD zone and the UCI from the FD zone to generate the UCI. For example, some UCI (e.g., a CSI and/or the like) may be split between the FD zone and the non-FD zone, or some UCI may be repeated in the FD zone and the non-FD zone. In such cases, the BS  110  may combine the UCI from each zone to form a combined UCI. 
     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 a priority-based approach for splitting UCI for FD communications, in accordance with various aspects of the present disclosure. Reference number  510  shows UCI to be transmitted by a UE (e.g., UE  120  and/or the like). Here, the UCI includes an ACK/NACK, an SR, and a CSI. A highest-priority UCI is at the leftmost side of example  500 , and the priority level deceases toward the right. For example, the ACK/NACK is associated with a highest priority level and the CSI is associated with a lowest priority level. 
     In some aspects, the UE may allocate the UCI into a non-FD zone part (shown by reference number  520 ) and an FD zone part (shown by reference number  530 ) based at least in part on respective priority levels of parts of the UCI. For example, the UE may identify a UCI bit sequence in accordance with respective priority levels of the parts of the UCI (e.g., ACK/NACK first, SR second, and CSI third). In other words, the UCI bit sequence may have a highest-priority UCI part first, a second-highest-priority UCI part second, and so on. The UE  120  may divide the UCI bit sequence into the two parts based at least in part on the resource size of the FD zone and the non-FD zone, where a first part is for the non-FD zone and the second part is for the FD zone. As shown, some UCI may be split between the FD zone and the non-FD zone (here, the CSI). In this way, the BS may configure the resource allocation for the FD zone and the non-FD zone, and the UE may allocate the CSI to the FD zone and the non-FD zone in accordance with the resource allocation. It should be understood that resource allocation and resource location are used interchangeably herein. 
     The first part, associated with the higher-priority UCI, may be transmitted in the non-FD zone (shown by reference number  540 ), thereby improving reliability and reducing SINR of the higher-priority UCI. The second part, associated with the lower-priority UCI, may be transmitted in the FD zone (shown by reference number  550 ), thus providing lower-priority UCI on a less reliable resource allocation. 
     As indicated above,  FIG. 5  is provided as an example. Other examples may differ from what is described with respect to  FIG. 5 . 
       FIG. 6  is a diagram illustrating an example process  600  performed, for example, by a user equipment, in accordance with various aspects of the present disclosure. Example process  600  is an example where a UE (e.g., UE  120  and/or the like) performs operations associated with split UCI for FD communications. 
     As shown in  FIG. 6 , in some aspects, process  600  may include receiving configuration information for an uplink control channel, wherein the configuration information includes at least one of a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone (block  610 ). For example, the UE (e.g., using antenna  252 , DEMOD  254 , MIMO detector  256 , receive processor  258 , controller/processor  280 , and/or the like) may receive configuration information for an uplink control channel. The configuration information may include at least one of a first resource identifier associated with a non-FD zone, or a second resource identifier associated with an FD zone, as described above. 
     As further shown in  FIG. 6 , in some aspects, process  600  may include transmitting UCI on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information (block  620 ). For example, the UE (e.g., using controller/processor  280 , transmit processor  264 , TX MIMO processor  266 , MOD  254 , antenna  252 , and/or the like) may transmit UCI on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information, as described above.

     Although  FIG. 6  shows example blocks of process  600 , in some aspects, process  600  may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in  FIG. 6 . Additionally, or alternatively, two or more of the blocks of process  600  may be performed in parallel. 
       FIG. 7  is a diagram illustrating an example process  700  performed, for example, by a base station, in accordance with various aspects of the present disclosure. Example process  700  is an example where a base station (e.g., base station  110  and/or the like) performs operations associated with split UCI for FD communications. 
     As shown in  FIG. 7 , in some aspects, process  700  may include transmitting configuration information for an uplink control channel, wherein the configuration information includes at least one of a first resource identifier associated with a non-FD zone, or a second resource identifier associated with an FD zone (block  710 ). For example, the base station (e.g., using controller/processor  240 , transmit processor  220 , TX MIMO processor  230 , MOD  232 , antenna  234 , and/or the like) may transmit configuration information for an uplink control channel. In some aspects, the configuration information includes at least one of: a first resource identifier associated with a non-FD zone, or a second resource identifier associated with an FD zone.

     In a twenty third aspect, alone or in combination with one or more of the first through twenty second aspects, the uplink control channel includes a first uplink control channel transmitted in the non-FD zone and a second uplink control channel transmitted in the FD zone. 
     In a twenty fourth aspect, alone or in combination with one or more of the first through twenty third aspects, the first uplink control channel uses a first format and the second uplink control channel uses a second format. 
     In a twenty fifth aspect, alone or in combination with one or more of the first through twenty fourth aspects, the first format and the second format are selected based at least in part on respective UCI types associated with the first uplink control channel and the second uplink control channel, or based at least in part on a symbol length of the first uplink control channel or the second uplink control channel. 
     In a twenty sixth aspect, alone or in combination with one or more of the first through twenty fifth aspects, the first uplink control channel and the second uplink control channel are associated with respective power control parameters that are independent from each other. 
     In a twenty seventh aspect, alone or in combination with one or more of the first through twenty sixth aspects, a power control parameter of the first uplink control channel is modified relative to a power control parameter of the second uplink control channel based at least in part on a power boosting ratio. 
     In a twenty eighth aspect, alone or in combination with one or more of the first through twenty seventh aspects, the first uplink control channel and the second uplink control channel are associated with respective power boosting ratios relative to an uplink shared channel transmit power. 
     Although  FIG. 7  shows example blocks of process  700 , in some aspects, process  700  may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in  FIG. 7 . Additionally, or alternatively, two or more of the blocks of process  700  may be performed in parallel. 
     The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the aspects to the precise form disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the aspects. 
     As used herein, the term “component” is intended to be broadly construed as hardware, firmware, and/or a combination of hardware and software. As used herein, a processor is implemented in hardware, firmware, and/or a combination of hardware and software. 
     As used herein, satisfying a threshold may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, not equal to the threshold, and/or the like. 
     It will be apparent that systems and/or methods described herein may be implemented in different forms of hardware, firmware, and/or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the aspects. Thus, the operation and behavior of the systems and/or methods were described herein without reference to specific software code—it being understood that software and hardware can be designed to implement the systems and/or methods based, at least in part, on the description herein. 
     Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set. A phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a-b, a-c, b-c, and a-b-c, as well as any combination with multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c or any other ordering of a, b, and c). 
     No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items, and may be used interchangeably with “one or more.” Furthermore, as used herein, the terms “set” and “group” are intended to include one or more items (e.g., related items, unrelated items, a combination of related and unrelated items, and/or the like), and may be used interchangeably with “one or more.” Where only one item is intended, the phrase “only one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” and/or the like are intended to be open-ended terms. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
