A base station can transmit downlink control information indicating a type of resource allocation to avoid errors. In other cases, a UE and / or a base station can specify a particular resource block group size to avoid potential errors. A UE and / or a base station can calculate the number of resource block groups for a bandwidth part and allocate the size of the resource block group based on that calculation. A UE and / or a base station can perform a comparison between the bandwidth part size and the resource block group size to determine whether to specify a different resource block group size to avoid errors. Similar techniques can be used to allocate resources for precoded resource block groups.

[0003] Background

[0004] The following generally relates to wireless communication and, more specifically, to determining transmission configurations for resource block groups and precoding resource block groups.

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be capable of supporting communication with multiple users by sharing available system resources, such as time, frequency, and power. Examples of such multi-access systems include fourth-generation (4G) systems, such as Long-Term Evolution (LTE) systems, LTE-Advanced (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 various 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 Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multi-access communication system may include several base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as User Equipment (UE).

[0006] In some wireless communication systems, a UE or a base station may determine an allocation of a resource structure in a specific frequency or frequency band. In some cases, the resource structure may be referred to as a resource block. The UE or the base station may determine a subset of contiguous resource blocks (which may be referred to as a bandwidth part) to identify where certain information can be transmitted. In some cases, when identifying the resource blocks of the bandwidth part, the device may identify conflicting information, which may result in transmission errors and / or reception errors.

[0007] Overview

[0008] The techniques described herein relate to improved methods, systems, devices, and apparatuses for supporting the determination of transmission configurations for resource block groups and precoded resource block groups. Generally, the techniques described herein provide processes for avoiding situations that may cause transmission errors or reception errors attributable to conflicting or incorrect resource block characteristics. In some cases, the base station may transmit downlink control information that indicates a resource allocation type to avoid potential errors. In other cases, the UE and / or the base station may specify a particular resource block group size to avoid potential errors. In these cases, the UE and / or the base station may calculate the number of resource block groups for a bandwidth part and allocate the size of the resource block group based on that calculation. In the same or different cases, the UE and / or the base station may perform a comparison between the bandwidth part size and the resource block group size to determine whether to specify a different resource block group size to avoid potential errors.

[0009] The techniques described herein may be similarly used to avoid potential errors based on precoded resource block groups. For example, the base station may transmit downlink control information that indicates a resource allocation type to avoid potential errors caused by the determination of the precoded resource block group size. In another example, the UE and / or the base station may specify a particular precoded resource block group size to avoid potential errors. In these cases, the UE and / or the base station may calculate the number of precoded resource block groups for a bandwidth part and allocate the size of the precoded resource block group based on that calculation. In the same or different cases, the UE and / or the base station may perform a comparison between the bandwidth part size and the precoded resource block group size to determine whether to specify a particular bandwidth part size to avoid potential errors.

[0095] Detailed description

[0096] In some wireless communication radio access technologies, one or more devices (e.g., user equipment (UE) and / or base stations) may allocate or determine various positions and sizes of resource structures within a frequency bandwidth, such as a carrier bandwidth. For example, a base station may allocate the positions of various resource blocks (e.g., physical resource blocks (PRB), common resource blocks (CRB), virtual resource blocks (VRB)) within the carrier bandwidth. In some cases, these resource block positions, sizes, and grouping may be allocated and determined with reference to a bandwidth part (BWP) of the carrier bandwidth and a point in the carrier bandwidth (e.g., point A where subcarrier 0 in the carrier bandwidth is centered). The bandwidth part may be a subset of contiguous common resource blocks defined within the carrier bandwidth.

[0097] Various techniques may be used to determine the resource block allocation within the carrier bandwidth. In some cases, a type 0 resource allocation (e.g., for more fine-grained resource allocation) may refer to a bit map including bits for each resource block group. A UE may receive a type 0 resource allocation (e.g., a bit map indicated via downlink control information), and may identify which resource block groups are included in a downlink grant based on a resource block group (RBG) configuration (e.g., the configuration or index of the RBG) and the individual 1s indicated by the bit map. A type 1 resource allocation may refer to a contiguous resource allocation indicated by a starting resource block or resource block group and an ending resource block or resource block group. In a type 0 allocation, a specified formula may be used to determine the resource block group sizes of the first and last resource block groups in the bandwidth part. However, in some cases, e.g., when the bandwidth part includes a single resource block group, the specified formula may result in different resource block group sizes for the first and last resource block groups, even though the first and last resource block groups are the same resource block group. These conflicting results may lead to errors in the resource allocation made by the base station and the resource identification made by the UE.

[0098] In addition, similar techniques may be used to identify precoding resource block groups within respective bandwidth parts in the carrier bandwidth. A UE may be configured to identify the sizes of the first and last precoding resource block groups of a bandwidth part. If the bandwidth part includes a single precoding resource block group, the UE may identify different sizes for the first and last precoding resource block groups, even though the first and last precoding resource block groups are the same precoding resource block group. These conflicting results may also lead to errors in the resource allocation made by the base station and the resource identification made by the UE.

[0099] The various techniques described herein can be used to avoid these potential errors. In one example technique, a base station can identify a specific resource allocation (e.g., a type 1 allocation) in downlink control information transmitted to a UE such that the described errors can be avoided. The base station can identify the specific resource allocation when determining that the identified transmission configuration results in a bandwidth part size that is less than or equal to a bandwidth part size threshold and further based on the resource block group size resulting from the transmission configuration. Thus, rather than allocating resources according to a first allocation type that may potentially cause the described errors, the base station instructs the UE to utilize a resource allocation that avoids the likelihood of such errors. In other examples, the UE and the base station can be configured to set the resource block group size equal to the bandwidth part size when the UE and the base station determine that certain conditions exist in the transmission configuration. These techniques can be similarly used to avoid errors caused in the allocation of precoded resource block groups.

[0100] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further described in the context of a wireless communication system that illustrates communication between a base station and a UE, a process flow diagram that illustrates a type of resource allocation specified by the base station, a process flow diagram that illustrates the specification of a resource block group size based on a calculation, and a process flow diagram that illustrates the specification of a resource block group size based on a comparison. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flowcharts associated with determining a transmission configuration.

[0101] Figure 1 An example of a wireless communication system 100 that supports determining a transmission configuration for a resource block group and a precoded resource block group in accordance with aspects of the present disclosure is illustrated. Wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, wireless communication system 100 can be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some cases, wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices.

[0102] Base station 105 may communicate wirelessly with UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, Node B, evolved Node B (eNB), next-generation Node B, or Gigabit Node B (any of which may be referred to as a gNB), home Node B, home evolved Node B, or some other suitable term. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be capable of communicating with various types of base stations 105 and network equipment, including macro eNBs, small cell eNBs, gNBs, relay base stations, and the like).

[0103] Each base station 105 may be associated with a particular geographic coverage area 110 in which communication with various UEs 115 is supported. Each base station 105 may provide communication coverage for the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. 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. The downlink transmission may also be referred to as a forward link transmission, and the uplink transmission may also be referred to as a reverse link transmission.

[0104] The geographic coverage area 110 of the base station 105 may be divided into sectors that form part of the geographic coverage area 110, and each sector may be associated with a cell. For example, each base station 105 may provide communication coverage for a macro cell, small cell, hotspot, or other type of cell, or various combinations thereof. In some examples, the base station 105 may be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, and the overlapping geographic coverage areas 110 associated with different technologies may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, where different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0105] The term "cell" refers to a logical communication entity for communicating with a base station 105 (e.g., on a carrier), and may be associated with an identifier to distinguish adjacent cells operating via the same or different carriers (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)). In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access for different types of devices (e.g., Machine Type Communication (MTC), NarrowBand Internet of Things (NB-IoT), Enhanced Mobile Broadband (eMBB), or others). In some cases, the term "cell" may refer to a part (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0106] Each UE 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where "device" may also be referred to as a unit, a station, a terminal, or a client. UE 115 may also be 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 also refer to a Wireless Local Loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which may be implemented in various articles (such as appliances, vehicles, meters, etc.).

[0107] Some UEs 115 (such as MTC or IoT devices) may be low-cost or low-complexity devices, and may provide automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to a data communication technology that allows devices to communicate with each other or a device to communicate with the base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices integrated with sensors or meters to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographical event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0108] Some UEs 115 may be configured to operate in a power consumption - reduced mode of operation, such as half - duplex communication (e.g., a mode that supports one - way communication via transmission or reception but does not support simultaneous transmission and reception). In some examples, half - duplex communication may be performed at a reduced peak rate. Other power - saving techniques for UEs 115 include entering a power - saving "deep - sleep" mode when not participating in active communication, or operating on a limited bandwidth (e.g., according to narrow - band communication). In some cases, UEs 115 may be designed to support critical functions (e.g., mission - critical functions), and the wireless communication system 100 may be configured to provide ultra - reliable communication for these functions.

[0109] In some cases, UEs 115 may also be able to communicate directly with other UEs 115 (e.g., using peer - to - peer (P2P) or device - to - device (D2D) protocols). One or more UEs in a group of UEs 115 that utilize D2D communication may be within the geographical coverage area 110 of the base station 105. Other UEs 115 in this group may be outside the geographical coverage area 110 of the base station 105 or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, each group of UEs 115 that communicate via D2D communication may utilize a one - to - many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0110] Base stations 105 may communicate with the core network 130 and with each other. For example, base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130) on a backhaul link 134 (e.g., via X2, Xn, or other interfaces).

[0111] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC), which can include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME can manage non-access stratum (e.g., control plane) functions such as the mobility, authentication, and bearer management of the UE 115 served by the base station 105 associated with the EPC. User IP packets can be transmitted through the S-GW, which itself can be connected to the P-GW. The P-GW can provide IP address allocation and other functions. The P-GW can be connected to the network operator IP services. The operator IP services can include access to the Internet, intranet, IP multimedia subsystem (IMS), or packet switched (PS) streaming services.

[0112] At least some network devices (such as the base station 105) can include sub-components, such as access network entities, which can be examples of access node controllers (ANCs). Each access network entity can communicate with each UE 115 through several other access network transmission entities, which can be referred to as radio heads, intelligent radio heads, or transmit / receive points (TRPs). In some configurations, the various functions of each access network entity or the base station 105 can be distributed across various network devices (e.g., radio heads and access network controllers) or combined into a single network device (e.g., the base station 105).

[0113] 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). Generally, the 300 MHz to 3 GHz division is called the ultra-high frequency (UHF) division or the decimeter band because the wavelengths are in the range of approximately 1 decimeter to 1 meter in length. UHF waves can be blocked or redirected by buildings and environmental features. However, these waves can penetrate various structures sufficiently for macrocells to provide service to the UE 115 located indoors. Compared with transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, the transmission of UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0114] The wireless communication system 100 can also operate in the super-high frequency (SHF) division using frequency bands from 3 GHz to 30 GHz (also known as the centimeter band). The SHF division includes frequency bands that can be opportunistically used by devices that can tolerate interference from other users (such as the 5 GHz industrial, scientific, and medical (ISM) band).

[0115] The wireless communication system 100 may also operate in the extremely high frequency (EHF) division of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as the millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency divisions, and the use of frequency bands designated across these frequency divisions may vary by country or regulatory body.

[0116] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency bands. For example, the wireless communication system 100 may employ licensed-assisted access (LAA), Long-Term Evolution Unlicensed (LTE-U) radio access technology, or New Radio (NR) technology in an unlicensed band such as the 5 GHz ISM band. When operating in an unlicensed radio frequency band, wireless devices such as the base station 105 and the UE 115 may employ a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operation in the unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with a component carrier operating in a licensed band. Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in the unlicensed spectrum may be based on frequency-division duplexing (FDD), time-division duplexing (TDD), or a combination of both.

[0117] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), where the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication can utilize multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which can be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, the receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of these multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0118] 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 (e.g., the base station 105 or the UE 115) to shape or direct an antenna beam (e.g., 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 the antenna elements of an antenna array such that signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals communicated via the antenna elements can include the transmitting device or the receiving device applying specific amplitudes and phase shifts to the signals carried via each antenna element associated with the device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0119] In one example, base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times in different directions by base station 105, which may include a signal being transmitted according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by base station 105 or a receiving device, such as UE 115) to identify the beam direction used by base station 105 for subsequent transmissions and / or receptions.

[0120] Some signals (such as data signals associated with a particular receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device (such as UE 115)). In some examples, the beam direction associated with a transmission in a single beam direction may be determined at least in part based on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signal that it received with the highest signal quality or other acceptable signal quality. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying the beam direction used by UE 115 for subsequent transmissions or receptions) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0121] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may attempt multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may attempt multiple receive directions by: receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device may use a single receive beam to receive in a single beam direction (e.g., when receiving a data signal). The single receive beam may be aligned in a beam direction determined at least in part based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based at least in part on listening according to multiple beam directions).

[0122] In some cases, the antennas of base station 105 or UE 115 may be located within one or more antenna arrays that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may co-locate at an antenna assembly such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 may be located at different geographical locations. Base station 105 may have an antenna array having several rows and columns of antenna ports for beamforming that base station 105 can use to support communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations.

[0123] In some cases, wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly for communication over logical channels. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use hybrid automatic repeat request (HARQ) to provide MAC layer retransmissions, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of the RRC connection that supports the radio bearers for user plane data between UE 115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0124] In some cases, UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput of the MAC layer in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback for data received in previous symbols in a particular slot during that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0125] Time intervals in LTE or NR can be expressed as multiples of a basic time unit, which may refer to, for example, the sampling period T s = 1 / 30,720,000 seconds). The time intervals of communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period can be expressed as T f = 307,200Ts 。A radio frame can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 ms. A subframe can be further divided into 2 time slots each having a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the smallest scheduling unit of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In other cases, the smallest scheduling unit of the wireless communication system 100 can be shorter than a subframe or can be dynamically selected (e.g., in a burst of shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0126] In some wireless communication systems, a time slot can be further divided into multiple mini-slots each containing one or more symbols. In some instances, the symbols of the mini-slots or the mini-slots can be the smallest scheduling unit. For example, the duration of each symbol can vary depending on the subcarrier spacing or the operating frequency band. Further, some wireless communication systems can implement time slot aggregation, where multiple time slots or mini-slots are aggregated together and used for communication between the UE 115 and the base station 105.

[0127] The term "carrier" refers to a set of radio frequency spectrum resources that has a defined physical layer structure for supporting communication on the communication link 125. For example, the carrier of the communication link 125 can include a portion of the radio frequency spectrum band that operates according to the physical layer channels for a given radio access technology. Each physical layer channel can carry user data, control information, or other signaling. A carrier can be associated with a predefined frequency channel (e.g., the evolved universal terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and can be located according to a channel grid for discovery by the UE 115. A carrier can be a downlink or an uplink (e.g., in the FDD mode), or be configured to carry downlink communication and uplink communication (e.g., in the TDD mode). In some examples, the signal waveform transmitted on a carrier can include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0128] For different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR), the organizational structure of a carrier can be different. For example, the communication on a carrier can be organized according to a TTI or a time slot, each of which can include user data and control information or signaling to support decoding of the user data. The carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), the carrier can also have acquisition signaling or control signaling to coordinate the operation of other carriers.

[0129] Physical channels can be multiplexed on a carrier according to various techniques. The physical control channel and the physical data channel can be multiplexed on a downlink carrier using, for example, time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. In some examples, the control information transmitted in the physical control channel can be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0130] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, this carrier bandwidth can be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth can be one of several predefined bandwidths of a carrier of a specific radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 can be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range within the carrier (e.g., a set of subcarriers or resource blocks (RBs)) (e.g., "in-band" deployment of the narrowband protocol type).

[0131] In a system adopting MCM technology, a resource element can include a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate of the UE 115 can be. In a MIMO system, the wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., spatial layers), and using multiple spatial layers can further increase the data rate of communicating with the UE 115.

[0132] Devices (e.g., base station 105 or UE 115) of wireless communication system 100 may have a hardware configuration that supports communication on a specific carrier bandwidth or may be configurable to support communication on one carrier bandwidth within a carrier bandwidth set. In some examples, wireless communication system 100 may include base station 105 and / or UE 115 that support simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0133] Wireless communication system 100 may support communication with UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both FDD and TDD component carriers.

[0134] In some cases, wireless communication system 100 may utilize enhanced component carriers (eCCs). An eCC may be characterized by one or more features including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have sub-optimal or non-ideal backhaul links). An eCC may also be configured to operate in unlicensed spectrum or shared spectrum (e.g., where more than one operator is permitted to use the spectrum). An eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by UE 115 that is not capable of monitoring the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to conserve power).

[0135] In some cases, an eCC may utilize a symbol duration different from other component carriers, which may include using a reduced symbol duration compared to the symbol duration of other component carriers. The shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. Devices (such as UE 115 or base station 105) that utilize an eCC may transmit broadband signals (e.g., according to a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). The TTI in an eCC may include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in the TTI) may be variable.

[0136] Wireless communication system 100 may be an NR system that can utilize any combination of licensed, shared, and unlicensed spectral bands, etc. The flexibility of eCC symbol duration and subcarrier spacing may allow eCCs to be used across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectral efficiency, particularly through dynamic vertical (e.g., across the frequency domain) and horizontal (e.g., across the time domain) sharing of resources.

[0137] In some radio access technologies for wireless communication, the base station 105 may allocate different resource structures within a frequency bandwidth (such as a carrier bandwidth). In some cases, the allocation of the resource structure within the frequency bandwidth may be referred to as the identification of a transmission configuration. In some cases, the identification of a transmission configuration includes identifying a resource allocation type based on the carrier bandwidth, operating conditions, UE capabilities, etc. In some examples, the resource allocation type may be indicated by higher layer signaling, and in some cases, the base station 105 may transmit downlink signaling (e.g., downlink control information (DCI), RRC signaling, etc.) including a grant indicating the resource allocation for downlink or uplink transmission. The DCI may include information about downlink scheduling assignments, uplink resource grants, transmission schemes, uplink power control, HARQ information, MCS, and other information. The size and format of the DCI message may vary depending on the type and amount of information carried by the DCI and factors such as bandwidth, number of antenna ports, and duplex mode.

[0138] The DCI may indicate the resource allocation within the carrier in various ways (e.g., a portion or range, such as a set of subcarriers, RBs, or RBGs). Type 0 resource allocation (e.g., for a more fine-grained resource allocation) may refer to a bit mapping including bits for each RBG. The UE 115 may receive a type 0 resource allocation (e.g., the bit mapping indicated by the DCI), and may identify which RBGs are included in the grant based on the RBG configuration (e.g., the configuration or index of the RBGs) and the individual 1s indicated by the bit mapping. Type 1 resource allocation may refer to a contiguous resource allocation indicated by a starting RB or RBG and an ending RB or RBG. In some cases, the use of type 0 or type 1 resource allocation may also depend on higher layer signaling, and the DCI may indicate the allocation according to the higher layer signaling.

[0139] In type 0 allocation, the RBG size of the first RBG and the last RBG in the bandwidth part may be determined using the formula specified by the type 0 allocation, as will be described in more detail below with reference to Figure 2 However, in certain cases, such as when the bandwidth part includes a single RBG, the specified formula may result in different RBG sizes for the first RBG and the last RBG, even though the first RBG and the last RBG are the same RBG. These conflicting results may lead to errors in the resource allocation made by the base station 105 and the resource identification made by the UE 115.

[0140] In addition, similar techniques can be used to identify precoded resource block groups (PRGs) within each BWP in the carrier bandwidth. UE 115 can be configured to identify the size of the first PRG of the BWP. If the BWP includes a single PRG, the UE can identify different sizes for the first and last PRGs based on the precoding granularity, even if the first and last PRGs are the same PRG. The results of these conflicts can also lead to errors in resource allocation made by the base station 105 and resource identification made by the UE 115.

[0141] The various techniques described herein can be used to avoid these potential errors. These techniques apply to both resource allocation via higher layer signaling and DCI-based resource allocation. In one example technique, the base station 105 can identify a specific resource allocation (e.g., downlink resource allocation type 1) in the downlink control information transmitted to the UE 115 such that the described errors can be avoided. The base station 105 can identify the specific resource allocation when determining that the identified transmission configuration results in a bandwidth part size that is less than or equal to a bandwidth part size threshold and further based on the resource block group size resulting from the transmission configuration. Thus, instead of allocating resources according to a second allocation type (e.g., type 0 allocation), which may potentially lead to the described errors, the base station 105 instructs the UE 115 to use a first resource allocation type (e.g., type 1 allocation) that avoids the possibility of such errors. In other examples, the UE 115 and the base station 105 can be configured to set the RBG size equal to the BWP size when the UE 115 and the base station 105 determine that certain conditions exist in the transmission configuration. These techniques can be similarly used to avoid errors caused in the allocation of precoded resource block groups.

[0142] Figure 2 An example of a wireless communication system 200 that supports determining a transmission configuration for a resource block group and a precoded resource block group in accordance with aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system includes a base station 105 and a UE 115. The base station 105 can communicate with the UE 115 on a downlink communication link 240 and an uplink communication link. The DCI 235 in the downlink communication link 240 can schedule downlink and uplink data communications. In the illustrated example, the DCI 235 schedules communication resources in the carrier bandwidth 210.

[0143] The carrier bandwidth 210 includes CRBs (e.g., CRB 220), PRBs 205, VRBs (not shown), and BWPs 215. Each BWP 215 includes a subset of contiguous PRBs, which can be a subset of a contiguous subset of CRBs within the carrier bandwidth 210. Accordingly, the PRBs 205 are defined within each BWP 215. Each BWP 215 can have a separate configuration, such as parameter design, bandwidth size, frequency position, and control resource set (CORESET). Each BWP 215 can be defined relative to a point A 230 corresponding to the center point of CRB0 220 of the carrier bandwidth 210. For example, BWP 0 215-a can be defined based on a parameter start BWP0 225-a, which indicates the first PRB (e.g., PRB0 205-a) of BWP 0 relative to CRB0 220. Each BWP 215 can include one or more RBGs (not shown), which can be a set of contiguous virtual resource blocks defined by higher layer parameters. The BWP215 and RBG can be allocated by the base station 105 according to DCI 235, higher layer signaling, or both. As mentioned, the base station 105 can indicate various allocation schemes (e.g., allocation types) for allocating resources of the carrier bandwidth 210. The allocation scheme can be selected based on factors such as granularity, UE communication type (e.g., low latency communication), type of UE 115 (e.g., Internet of Things (IoT) device), etc. In some cases, the allocation scheme can be determined based on a transmission configuration, which can be indicated by higher layer signaling.

[0144] Each allocation scheme can specify a technique for determining the location of the BWP 215 and the number of RBGs within the BWP 215 and other information. In some cases, the allocation scheme can specify a technique (e.g., formula) for determining the number of RBGs within the BWP 215. For example, in downlink resource allocation type 0, the resource block assignment information can include a bit map indicating the RBGs allocated to the UE 115. According to downlink resource allocation type 0, for a downlink BWP i of size number of PRBs, the total number of RBGs (N RBG ) is given by where: the size of the first RBG is

[0145] However, the value of the last RBG size depends on various conditions.

[0146] If then the size of the last RBG is

[0147]

[0148] Otherwise, the size of the last RBG is P. (Equation 2b)

[0149] Accordingly, Equation 1 and Equations 2a and 2b can be used to determine the size of the edge RBGs (e.g., the first RBG and the last RBG of BWP 215). However, in the case where P = 2 (e.g., the RBG size is 2), and (e.g., the size of BWP 215 is one resource block), the first RBG size and the last RBG size may produce different results. In such cases, the first RBG and the last RBG are the same RBG because the BWP size is one resource block.

[0150] Equation 1 gives:[[]]

[0151] And Equation 2 gives:[[]]

[0152] Accordingly, in this case, the first RBG and the last RBG are the same RBG, which means that the two equations provide conflicting results. The base station 105 may incur errors in allocating resources in such cases, and / or the UE 115 may incur errors in decoding the received signal in such cases.

[0153] In a first option for avoiding such errors, the base station 105 may configure the UE 115 (e.g., via DCI 235) such that the UE 115 does not expect the BWP 215 size to be less than the RBG size (e.g., P). In other words, the base station 105 may allocate resources such that the cases where conflicting results may occur can be avoided. To avoid errors, the base station 105 may consider whether the BWP size is less than or equal to a threshold based on the resource block group size when identifying the transmission configuration. For example, if during the identification of the transmission configuration, the base station 105 determines that the BWP size is 1 and the RBG size is 2, the base station 105 may use type 1 allocation to allocate resources. In type 1 allocation (e.g., the second resource allocation type), the equations for calculating the first RBG size and the last RBG size are not used (as may be the case for type 0 allocation). Instead, in type 1 allocation (e.g., the first resource allocation type), DCI 235 may indicate the starting resource block and the ending resource block, where the resource blocks within the resource block group are consecutive. Based on type 1 allocation, the base station 105 can avoid errors in allocating resources for transmission, and the UE 115 can avoid errors in decoding the received transmission based on the DCI 235 indicating type 1 allocation. Similarly, if the identified transmission configuration indicates that the BWP size is less than or equal to three resource blocks and the RBG size is equal to four resource blocks, the base station 105 may use type 1 allocation to allocate resources.

[0154] In some cases, the threshold may be based on or equal to the RBG size. As mentioned, if the RBG size is two resource blocks and the BWP size is less than 2 (e.g., one resource block), then a type 1 allocation may be specified. Similarly, if the RBG size is three resource blocks and the BWP is less than or equal to three, then a type 1 allocation may be specified. Accordingly, the threshold may be set to be less than or equal to the BWP size in some cases.

[0155] In a second option for avoiding such errors, the base station 105 and the UE 115 may be configured to account for edge cases that may potentially cause errors by specifying the RBG size for the transmission configuration to be equal to the BWP size based on the calculated RBG number being equal to one. In other words, if the number of RBGs in the BWP 215 is equal to one, then the RBG size is specified to be equal to the BWP size. Accordingly, the base station 105 may determine the initial RBG size and BWP size based on various factors and using type 0 resource allocation. After determining the RBG size and BWP size, the base station 105 may calculate the RBG number based on the provided formula or according to type 0 resource allocation. In other words, the base station 105 calculates the RBG number according to the formula specified by type 0 allocation. If the RBG number is equal to one, then the base station 105 may specify (e.g., modify) the RBG size to be equal to the BWP size.

[0156] The UE 115 may receive DCI 235 indicating type 0 resource allocation, determine the RBG size, BWP size, and BWP start based on the transmission configuration, and calculate the RBG number based on the RBG size, BWP size, and BWP start. In some cases, the RBG size, BWP size, and BWP start are indicated in the DCI 235. The UE 115 may calculate the RBG number to be equal to one. In such cases, the UE 115 may specify the RBG size to be equal to the BWP size and decode the corresponding transmission based on this specification.

[0157] In a third option for avoiding errors, the base station 105 and the UE 115 may be configured to account for edge cases that may potentially cause errors by specifying the RBG size for the transmission configuration to be equal to the BWP size based on a comparison between the sum of the BWP size modulo the RBG size and the starting bandwidth part and the RBG size. The third option may be illustrated by the following formula:

[0158] If then the RBG size is

[0159] Accordingly, the base station 105 may determine the initial RBG size and BWP size based on various factors and using type 0 resource allocation. After determining the RBG size and BWP size, the base station 105 may perform a comparison. Based on the result of the comparison, the base station 105 may specify (e.g., modify) the RBG size to be equal to the BWP size.

[0160] The UE 115 may receive DCI 235 indicating type 0 resource allocation, determine the RBG size and BWP size based on the transmission configuration, and perform a comparison. Based on the result of the comparison, the UE 115 may specify the RBG size to be equal to the BWP size and decode the corresponding transmission based on the specification.

[0161] Similar errors may occur when determining the PRG size within the bandwidth part 215. For example, when the precoding granularity is based on one of the values 2 or 4, the following procedures may be used to identify the size of the edge (e.g., first and last) PRGs in the BWP.

[0162] The size of the first PRG is given by

[0163]

[0164] However, the value of the last PRG size depends on various conditions. If then the size of the last PRG is given by

[0165]

[0166] And if then the size of the last PRG is

[0167] P BWP,i . (Formula 4b)

[0168] If P BWP,i = 2, and then using formulas 3, 4a, and 4b, the size of the first PRG is: 2 - 0 mod 2 = 2, and the size of the last PRG is: (0 + 1) mod 2 = 1. However, in this case, the first PRG and the last PRG are the same PRG, which means that the two formulas provide contradictory results.

[0169] In a first option for avoiding such errors, the base station 105 may configure the UE 115 (e.g., via DCI 235) such that the UE 115 may not expect the BWP 215 size to be less than the PRG size. In other words, the base station 105 may allocate resources such that situations in which contradictory results may occur can be avoided. To avoid errors, the base station 105 may consider whether the BWP size is less than or equal to a threshold based on the PRG size when identifying the transmission configuration. For example, if during the identification of the transmission configuration, the base station 105 determines that the BWP size is 1 and the RBG size is 2, the base station 105 may use broadband allocation (e.g., broadband precoding granularity) to allocate resources. Accordingly, the formulas for calculating the first PRG size and the last PRG size may not be used. Accordingly, the base station 105 may avoid errors when allocating resources for transmission, and the UE 115 may avoid errors when decoding the received transmission. Similarly, if the identified transmission configuration indicates that the BWP size is less than or equal to three resource blocks and the PRG size is equal to four resource blocks, the base station 105 may use broadband allocation to allocate resources.

[0170] In a second option for avoiding such errors, the base station 105 and the UE 115 may be configured to account for edge cases that may potentially cause errors by specifying the PRG size for the transmission configuration to be equal to the BWP size based on the calculated number of PRGs being equal to one. In other words, if the number of PRGs in the BWP 215 is equal to one, the PRG size is specified to be equal to the BWP size. Accordingly, the base station 105 may determine the initial PRG size and the BWP size based on various factors. After determining the PRG size and the BWP size, the base station 105 may calculate the number of PRGs based on the provided formula. If the number of PRGs is equal to one, the base station 105 may specify (e.g., modify) the PRG size to be equal to the BWP size.

[0171] The UE 115 may receive DCI 235 indicating a specific resource allocation, determine the PRG size and the BWP size based on the transmission configuration, and calculate the number of PRGs based on the PRG size, the BWP size, and the start of the BWP. The UE 115 may calculate the number of PRGs to be equal to one. In such cases, the UE 115 may specify the PRG size to be equal to the BWP size and decode the corresponding transmission based on this specification.

[0172] In a third option for avoiding errors, the base station 105 and the UE 115 may be configured to account for edge cases that may potentially cause errors by specifying the PRG size for the transmission configuration to be equal to the BWP size based on a comparison between the sum of the BWP size modulo the PRG size and the start bandwidth part and the PRG size. The third option may be illustrated by the following formula:

[0173] If The PRG size is then

[0174] Accordingly, base station 105 can determine the initial PRG size and BWP size based on various factors. After determining the PRG size and BWP size, base station 105 can perform a comparison. Based on the result of the comparison, base station 105 can specify (e.g., modify) the PRG size to be equal to the BWP size.

[0175] UE 115 can receive DCI 235 indicating a specific resource allocation, determine the PRG size and BWP size based on the transmission configuration, and perform a comparison. Based on the result of the comparison, UE 115 can specify the PRG size to be equal to the BWP size and decode the corresponding transmission based on this specification. The PRG value (e.g., P BWP,i ) can be provided to UE by DCI, RRC, or both.

[0176] Figure 3 An example of process flow diagram 300 that supports determining a transmission configuration for a resource block group and a precoded resource block group in accordance with aspects of the present disclosure is illustrated. In some examples, process flow diagram 300 can implement aspects of wireless communication system 100. The process flow diagram includes base station 105 and UE 115.

[0177] At 305, base station 105 identifies a transmission configuration. The transmission configuration can be identified for scheduling a transmission to UE 115 or for transmitting a downlink grant to UE 115. In some cases, the transmission configuration can be determined based on carrier bandwidth, UE capabilities, communication environment, etc. In some cases, the transmission configuration can be based on a resource allocation type indicated by higher layer signaling. The transmission configuration can indicate a resource block group size and a bandwidth part size. The resource block group size and the bandwidth part size can be determined based on the resource allocation type (e.g., allocation type 0).

[0178] At 310, base station 105 specifies a first resource allocation type for the transmission configuration rather than a second resource allocation type for the transmission configuration for allocating resources to the carrier bandwidth. The specification can be at least partially based on the bandwidth part size being less than or equal to a bandwidth part size threshold and further at least partially based on the resource block group size. For example, base station 105 can determine that the bandwidth part size is one resource block and the resource block group size is two resource blocks. In another example, base station 105 can determine that the bandwidth part size is less than or equal to three resource blocks and the resource block group size is equal to four resource blocks. In some cases, the first resource allocation type is a type 1 allocation and the second resource allocation type is a type 0 allocation.

[0179] At 315, the base station 105 transmits downlink control information to the UE 115. The downlink control information may indicate a first resource allocation type for a transmission configuration. Based on a type 1 allocation, the downlink control information may indicate a resource block start parameter and a number of resource blocks.

[0180] At 320, the base station 105 transmits a data transmission to the UE 115. The data may be allocated according to the first resource allocation type. At 325, the UE 115 decodes the received data transmission based on the first resource allocation type indicated in the DCI.

[0181] Figure 3 The operations illustrated may be similarly applied in a precoded resource block group scenario. For example, at 305, the base station 105 may identify a transmission configuration indicating a bandwidth part size and a precoded resource block group size. At 310, the base station 105 may specify that a first resource allocation type (e.g., wideband) is preferred over a second resource allocation type (e.g., 2 or 4) based on the bandwidth part size being less than or equal to a bandwidth part size threshold. At 315, the base station 105 may transmit DCI indicating an allocation for the precoded resource block group, and at 320, the base station 105 may transmit a data transmission that is decoded by the UE 115 at 325 according to the indicated allocation.

[0182] Figure 4 An example of a process flow diagram 400 supporting determining a transmission configuration for a resource block group and a precoded resource block group in accordance with aspects of the present disclosure is illustrated. In some examples, the process flow diagram 400 may implement aspects of the wireless communication system 100. The process flow diagram 400 may include a base station 105 and a UE 115.

[0183] At 410, the UE 115 may transmit a UE capability indication to the base station 105. The capability indication may indicate that the UE 115 is capable of decoding messages based on a bandwidth part size specification, as described herein. If the UE 115 is not capable of performing a bandwidth part size specification, the base station 105 may implement other techniques, as described herein.

[0184] At 415, the base station 105 (e.g., a first device) identifies a transmission configuration for a carrier bandwidth allocated to communication with the UE 115 (e.g., a second device). The transmission configuration may indicate a resource block group size and a bandwidth part size. In some cases, the transmission configuration may be identified according to a type 0 allocation and based on various factors such as carrier bandwidth, UE capabilities, communication environment, etc.

[0185] At 420, the base station 105 calculates the number of resource block groups for the transmission configuration at least in part based on the indicated resource block group size and bandwidth part size and according to a first resource allocation type. In some cases, the first resource allocation type can be a type 0 resource allocation, which can provide a formula for calculating the number of resource block groups.

[0186] At 425, the base station 105 designates the resource block group size for the transmission configuration to be equal to the bandwidth part size based at least on the calculated number of resource block groups being equal to one. At 430, the base station 105 communicates with the UE 115 by transmitting data transmissions to the UE 115 using the carrier bandwidth and according to the transmission configuration. The data transmissions can be allocated according to the designated resource block group size. In some cases, the DCI transmission can indicate the allocation type to the UE 115.

[0187] At 435, the UE 115 (e.g., the first device) can identify the transmission configuration of the received data transmission. In some cases, the identification is based on the received DCI indicating the resource allocation type. The transmission configuration can indicate the resource block group size and the bandwidth part size.

[0188] At 440, the UE 115 can calculate the number of resource block groups for the transmission configuration at least in part based on the resource block group size and the bandwidth part size and according to the first resource allocation type. For example, the UE 115 can calculate the resource block group size according to a type 0 allocation, which can specify a formula for calculating the resource block group size.

[0189] At 445, the UE 115 can designate the resource block group size of the transmission configuration to be equal to the bandwidth part size based at least on the calculated number of resource block groups being equal to one. At 450, the UE 115 decodes the data transmission based on the designated resource block group size.

[0190] Figure 4 The illustrated operations can be similarly used in a precoded resource block group scenario. For example, at 405, the UE can indicate the ability to specify a precoded resource block group size based on a calculation. At 415, the base station 105 can identify a transmission configuration indicating a transmission part size and a precoded resource block group size. At 420, the base station 105 can calculate the number of precoded resource block groups for the transmission configuration based on the precoded resource block group size and the bandwidth part size. At 425, the base station 105 can designate the PRG size based on the calculated number of precoded resource block groups being equal to one, and at 430, the base station 105 can send a data transmission specifying an allocation according to the PRG size. The UE 115 can similarly perform the procedures for decoding the transmission based on the designated PRG size.

[0191] Figure 5An example of process flow diagram 500 for determining a transmission configuration for a resource block group and a precoded resource block group in accordance with aspects of the present disclosure is illustrated. In some examples, process flow diagram 500 may implement aspects of wireless communication system 100. Process flow diagram 500 may include base station 105 and UE 115.

[0192] At 510, UE 115 may transmit a UE capability indication to base station 105.

If UE 115 is not capable of performing bandwidth part size specification, base station 105 may implement other techniques, as described herein.

The transmission configuration may indicate a resource block group size and a bandwidth part size. In some cases, the transmission configuration may be allocated according to type 0 and identified based on various factors such as carrier bandwidth, UE capability, communication environment, etc.

In some cases, the identification is based on the received DCI indicating the resource allocation type.

At 515, the base station 105 may identify a transmission configuration that indicates the transmission part size and the precoded resource block group size. At 520, the base station 105 may perform a comparison to determine whether the sum of the bandwidth part size modulo the precoded resource block group size and the starting bandwidth part of the carrier bandwidth is less than or equal to the precoded resource block group size. At 525, the base station 105 may specify the PRG size based on this determination, and at 530, the base station 105 may send a data transmission allocation specified according to the PRG size to the UE. The UE 115 may similarly execute procedures for decoding the transmission based on the specified PRG size.
