Description

Technical Field

[0001] The present specification relates generally to wireless communication networks, and more particularly, for example but not limited to, to multiple resource set configurations. Background Art

[0002] In the fourth generation (4G) long term evolution (LTE) broadband cellular network technology, the time resources and frequency resources of the physical layer (PHY) channel are directly indicated by the downlink (DL) control information (DCI). For DL ​​or uplink (UL) PHY channels, only one resource indication method is used. The scheduling granularity in the time domain is represented by time slots or subframes, while the scheduling of multiple sites in the frequency domain occupies different parts of the cell system bandwidth.

[0003] In the fifth generation (5G) broadband cellular network technology, the requirements for scheduling flexibility in the time and frequency domains have increased. In the time domain, scheduling is based on the slot level and the symbol level. In the frequency domain, the scheduling scope is divided into partial bandwidths (BWPs) that can be different for different sites. As in 4G LTE, code domain resources are indicated for certain PHY control channels. BRIEF DESCRIPTION OF THE DRAWINGS

In order to provide a thorough understanding of the present technology, the specific embodiments include specific details. However, the present technology is not limited to the specific details set forth herein, and can be practiced without one or more of these specific details. As will be appreciated by those skilled in the art, the described implementations can be modified in various different ways without departing from the scope of the present disclosure. Therefore, the drawings and descriptions should be considered illustrative rather than restrictive in nature. In one or more examples, structures and components are shown in the form of block diagrams to avoid making the concepts of the present technology unclear.

[0015] In 4G LTE, the same resource set is configured for the PHY channel regardless of the configuration in other domains. However, the potential of the 5G system for flexible scheduling with acceptable signaling overhead cannot be fully utilized through the direct DCI indication method. The present technology is used to configure different resource sets corresponding to different configurations in at least one of the following domains: demodulation reference signal (DM-RS) mapping type, partial bandwidth (BWP) configuration, component carrier (CC), serving cell, transmission waveform or multiple access scheme, PDCCH configuration. By configuring different resource sets in each of the above domains, the number of resources can be doubled. Therefore, the present technology provides a new method that can achieve much greater flexibility than the traditional 4G LTE method without any additional PHY signaling overhead.

[0020] Figure 1 1 is a diagram illustrating a wireless communication system 100 according to one or more embodiments. Not all depicted components are required; however, one or more embodiments may include additional components not shown in the diagram. The arrangement and type of components may be changed without departing from the scope of the claims set forth herein. Additional components, different components, or fewer components may be provided.

[0021] The wireless communication system 100 includes base stations and / or access points 112, 116, wireless communication devices 118-132, and a central node 134. It should be noted that the central node 134 includes a core network device, and the core network device or part of the functions of the core network device (such as user plane functions) can be integrated into the base station and / or access point 112. It should also be noted that the wireless communication devices 118-132 can be laptop computers 118 and 126, personal digital assistant hosts 120 and 130, personal computer hosts 124 and 132, tablet host 122, cellular phone host 128, or other stations mentioned above.

[0022] The wireless communication devices 122, 123, and 124 are located within the independent service area 109 and communicate directly (e.g., point-to-point). In this configuration, the wireless communication devices 122, 123, and 124 can only communicate with each other. In order to communicate with other wireless communication devices within the wireless communication system 100, or to communicate with the outside of the wireless communication system 100, the wireless communication devices 122, 123, and / or 124 can be attached to one of the base stations or access points 112 or 116.

[0023] Base stations or access points 112, 116 are located within service areas 111 and 113, respectively, and are operably coupled to a central node 134 via local area network connections 136, 138. Such connections provide base stations or access points 112, 116 with connections to other devices within the wireless communication system 100, and provide connections to other networks via WAN connections 142. In order to communicate with wireless communication devices 118-132 within service areas 111 and 113, each base station or access point 112, 116 has an associated antenna or antenna array. In one or more embodiments, the base station or access point 112 communicates wirelessly with wireless communication devices 118 and 120 at the same time as the base station or access point 116 communicates wirelessly with wireless communication devices 126-132. Wireless communication devices 118-132 can register with a particular base station or access point 112, 116 to receive service from the wireless communication system 100.

[0024] According to some embodiments, the base station is used for broadband cellular network systems (e.g., 5G, LTE, Advanced Mobile Phone Service (AMPS), Digital AMPS, GSM, CDMA, Local Multipoint Distribution System (LMDS), Multi-way Multipoint Distribution System (MMDS), Enhanced Data Rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA and / or its variants), and similar types of systems, while the access point is used for indoor or in-building wireless networks (e.g., IEEE 802.11, Bluetooth, ZigBee, any other type of radio frequency-based network protocol and / or its variants). Regardless of the specific type of communication system, each wireless communication device includes a built-in wireless device and / or is coupled to a wireless device.

[0025] Figure 2 An exemplary wireless communication device 200 is shown in accordance with one or more embodiments of the present technology. Not all of the depicted components are required; however, one or more embodiments may include additional components not shown in the figure. The arrangement and type of components may be changed without departing from the scope of the claims set forth herein. Additional components, different components, or fewer components may be provided.

[0026] The wireless communication device 200 includes a radio frequency (RF) antenna 210, a duplexer circuit 215, a transceiver circuit 205, a memory 250, a processor 260, a local oscillator generator (LOGEN) 270, and a power supply circuit 280. The transceiver circuit 205 includes a receiver circuit 220 and a transmitter circuit 230. The wireless communication device 200 also includes a baseband processing circuit 240. The baseband processing circuit 240 is usually separate from the transceiver. In another example, the baseband processing circuit 240 can also be integrated with the transceiver to form a component (such as Figure 2 In various embodiments of the present technology, Figure 2 One or more of the boxes shown in the figure may be integrated on one or more semiconductor substrates. For example, boxes 220-270 may be implemented in a single chip or a single system on chip, or may be implemented in a chipset of a multi-chip. In various embodiments, one or more boxes may be added. In various embodiments, one or more of the boxes shown may be removed or replaced by one or more other boxes. The wireless communication device 200 corresponds to the wireless communication device 128 or includes at least a portion of the wireless communication device 128.

[0027] RF antenna 210 may be adapted to transmit and / or receive RF signals (eg, wireless signals) over a wide frequency range (eg, 400 MHz - 6 GHz, 20 GHz - 44 GHz, 20 GHz - 86 GHz, 24 GHz - 53 GHz, 86 GHz - 98 GHz). Although a single RF antenna 210 is shown, the technology is not so limited.

[0028] The duplexer circuit 215 can provide isolation in the transmit frequency band to avoid saturation of the receiver circuit 220 or damage to components of the receiver circuit 220, and relax one or more design requirements of the receiver circuit 220. In addition, the duplexer circuit 215 can attenuate noise in the receive frequency band. The duplexer circuit 215 can be operable in multiple frequency bands under various standards (e.g., wireless standards, broadband cellular standards). The duplexer circuit 215 may include a transmit / receive (T / R) switch for selecting a receive or transmit mode of the wireless communication device 200. The T / R switch can be controlled by the baseband processing circuit 240.

[0029] Receiver circuit 220 may include suitable logic circuits and / or code that can be used to receive and process input RF signals from RF antenna 210. For example, receiver circuit 220 may be used to amplify and / or down-convert received wireless signals. In some embodiments of the present technology, receiver circuit 220 may be used to eliminate noise in received signals and may be linear over a wide frequency range. In this way, receiver circuit 220 may be suitable for receiving signals according to various wireless standards and broadband cellular standards. As non-limiting examples, such standards may include 5G, 4G LTE, 3G, GSM, Wi-Fi, WiMAX, and Bluetooth.

[0030] The transmitter circuit 230 may include suitable logic circuits and / or code that may be used to process and transmit signals from the RF antenna 210. For example, the transmitter circuit 230 may be used to up-convert the baseband processed signal to an output RF signal and amplify the output RF signal. In some embodiments of the present technology, the transmitter circuit 230 may be used to up-convert and amplify baseband signals processed according to various wireless standards. In some embodiments of the present technology, the transmitter 230 may be used to provide further amplification of the signal through one or more power amplifiers. In one or more embodiments, the transmitter 230 includes a power amplifier for amplifying the output RF signal.

[0031] The baseband processing circuitry 240 may include suitable logic, circuitry, interfaces, and / or code that may be operable to perform processing of baseband signals. For example, the baseband processing circuitry 240 may analyze received signals and generate control signals and / or feedback signals for configuring various components of the wireless communication device 200 (e.g., the receiver circuitry 220). The baseband processing circuitry 240 may be operable to encode, decode, transcode, modulate, demodulate, encrypt, decrypt, scramble, descramble, and / or otherwise process data in accordance with one or more wideband cellular standards.

[0032] The memory 250 may include suitable logic, circuitry, and / or code capable of storing various types of information (e.g., received data, generated data, code, and / or configuration information). For example, the memory 250 may include a random access memory (RAM), a read-only memory (ROM), flash memory, and / or a magnetic storage device. In some embodiments of the present technology, the information stored in the memory 250 may be used to configure the receiver circuit 220 and / or the baseband processing circuit 240.

[0033] The processor 260 may include suitable logic, circuitry, and / or code that may be capable of processing data for the wireless communication device 200 and / or controlling the operation of the wireless communication device 200. In this regard, the processor 260 may be capable of providing control signals to various other components of the wireless communication device 200. The processor 260 may also control data transmission between various components of the wireless communication device 200. In addition, the processor 260 may be capable of implementing an operating system or executing code to manage the operation of the wireless communication device 200.

[0034] The local oscillator generator (LOGEN) 270 may include suitable logic, circuitry, interfaces, and / or code that may be used to generate one or more oscillating signals of one or more frequencies. The LOGEN 270 may be used to generate digital and / or analog signals. In this manner, the LOGEN 270 may be used to generate one or more clock signals and / or sinusoidal signals. For example, the characteristics of the oscillating signals such as frequency and duty cycle may be determined based on one or more control signals from the processor 260 and / or the baseband processing circuit 240. In one or more embodiments, the LOGEN 270 may employ a crystal oscillator to generate the clock signals and / or sinusoidal signals.

[0035] The power supply 280 may include suitable logic, circuitry, and / or code that may be operable to provide power (e.g., a regulated voltage) to components within the wireless communication device 200. For example, the power supply 280 may provide power to the duplexer 215, the receiver 220, the transmitter 230, the baseband processing circuit 240, the memory 250, the processor 260, and the LOGEN 270.

[0036] In operation, the processor 260 can configure various components of the wireless communication device 200 based on the standard according to which the wireless communication device 200 receives signals. The wireless signal can be received via the RF antenna 210 and amplified and down-converted by the receiver circuit 220. The baseband processing circuit 240 can perform noise estimation and / or noise cancellation of the baseband signal, decoding and / or demodulation of the baseband signal. In this way, the information in the received signal can be appropriately recovered and utilized. For example, the information can be audio, text, image, video, multimedia and / or control signals to be presented to the user of the wireless communication device 200, data to be stored in the memory 250, and / or information that affects and / or enables the operation of the wireless communication device 200. The baseband processing circuit 240 can modulate, encode and perform other processing on the audio, text, image, video, multimedia and / or control signals to be sent by the transmitter circuit 230 according to various standards. The power supply 280 can provide one or more regulated mains voltages for various components of the wireless communication device 200.

[0037] In certain broadband cellular network standards (e.g., 5G), physical channels can be divided into downlink channels (e.g., physical downlink shared channel (PDSCH) and physical downlink control channel (PDCCH)) and uplink channels (e.g., physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH)). The PDCCH signal is used to transmit downlink control information, which notifies the user equipment about the resource allocation or scheduling of downlink resource allocation, uplink resource authorization, and uplink power control commands on the PDSCH. The PDCCH signal is demodulated at the user equipment based on the cell-specific reference signal (CRS). In a 5G broadband cellular network system, the start symbol in a physical resource block (abbreviated as "PRB") can indicate control information in a downlink transmission (e.g., downlink control information, abbreviated as "DCI").

[0038] It should also be understood that in the embodiments of the present technology, the physical resources may include time domain resources and frequency domain resources. In the time domain, the resource occupies M symbols (e.g., OFDM symbols), where M is a positive integer equal to or greater than 1. In the frequency domain, the frequency domain resource occupies N units, where each of the N units includes K consecutive subcarriers in the frequency domain, where N is a positive integer greater than or equal to 1, and K is a positive integer equal to or greater than 2. The physical resources may also include at least one of time domain resources and frequency domain resources, code domain resources, or space domain resources.

[0039] Figure 3 A flow chart of an example process 300 for determining resources from a configured set of resources is shown. Furthermore, for illustrative purposes, the blocks of process 300 are described herein as occurring serially or linearly. However, multiple blocks of process 300 may occur in parallel. Additionally, the blocks of process 300 need not be performed in the order shown, and / or one or more blocks of process 300 need not be performed and / or may be replaced by other operations.

[0040] In 4G LTE, the same resource set is configured for the PHY channel regardless of the configuration in other domains. In order to keep the DCI within the acceptable signaling overhead, a very limited bit width is used in the resource allocation bit field of the DCI, so the number of configurable resources is greatly limited. A combination of RRC configuration and DCI indication can be used for resource allocation in 5G systems, for example, the candidate resource set is configured through RRC signaling, and then the DCI indicates Figure 3 The index of a resource in the "resource table" or "resource collection" depicted in .

[0041] In this regard, process 300 begins at step 301, where a station (e.g., 128, 200) determines actual resources from N resources in a configured resource set, where N is a positive integer. Next, at step 302, the station occupies the determined resources to receive PDSCH signals in a downlink transmission from a base station (e.g., 116), or to send PDSCH / PUCCH signals in an uplink transmission to the base station. However, since the acceptable DCI signaling overhead is greatly limited, the bit field width used for resource allocation may be only 2 to 6 bits wide. Using this limited bit width, the configured resource set (or table) can only contain N=4-64 resources.

[0042] Considering that multiple dimensions need to be included in the resource configuration, such as starting slot, number of slots, starting symbol, number of symbols in a slot, starting physical resource block (PRB), number of PRBs, code domain parameters (e.g. sequence index, cyclic shift (CS) index, orthogonal code cover (OCC) index), and frequency hopping parameters (e.g. hopping on / off, frequency position of the second hop), the flexibility provided by a resource set (or table) for a PHY channel is greatly limited. The direct DCI indication method cannot fully exploit the potential of 5G systems for flexible scheduling with acceptable signaling overhead.

[0043] The present technology configures at least two resource sets for a PHY channel or signal (e.g., PDSCH, PUSCH, PDCCH, PUCCH, physical random access channel (PRACH), channel state information reference signal (CSI-RS), scheduling request (SR) or sounding reference signal (SRS), etc.), wherein different resource sets corresponding to different configurations in at least one of the following domains may be configured: demodulation reference signal (DM-RS) mapping type, fractional bandwidth (BWP) configuration, component carrier (CC), serving cell, transmission waveform or multiple access scheme, PDCCH configuration.

[0044] In some examples, different resource sets may be configured for different DM-RS mapping types (e.g., PDSCH / PUSCH mapping types A and B). For PDSCH mapping type A, the time position of the first DM-RS symbol may be defined relative to the start of the time slot. For PDSCH mapping type B, the time position of the first DM-RS symbol may be defined relative to the start of the scheduled PUSCH resources. For PUSCH mapping type A, the time position of the first DM-RS symbol may be defined relative to the start of the time slot. For PUSCH mapping type B, the time position of the first DM-RS symbol may be defined relative to the start of the scheduled PUSCH resources.

[0045] In other examples, different resource sets may be configured for different BWP configurations. In still other examples, different resource sets may be configured for different component carriers (CCs) in carrier aggregation. In still other examples, different resource sets may be configured for different serving cell configurations. In still other examples, different resource sets may be configured for different transmission waveforms or multiple access schemes, depending on whether transform precoding is used in UL transmission. In still other examples, different resource sets may be configured for different PDCCH configurations (e.g., different periodic configurations and / or time position configurations of CORESET, search space, and / or monitoring opportunities).

[0046] In some embodiments, the resources are configured to have one or more parameters in the time domain, frequency domain, code domain, and / or space domain. If the two resources are different, the value of at least one parameter for the two resources is different. If the configurations of the two resource sets are different, at least one resource in the first resource set is not included in the second resource set.

[0047] According to one or more embodiments of the present technology, a station (e.g., wireless communication device 128, wireless communication device 200) determines a first resource configuration among multiple resource configurations in at least one domain of multiple domains associated with a PHY channel or signal. For example, the station first determines a resource set to be selected for a PHY channel or signal (e.g., PDSCH, PUSCH, PUCCH, CSI-RS, SRS, SR, PDCCH, PRACH, etc.). The multiple domains may include, but are not limited to, DM-RS mapping type, BWP configuration, component carrier configuration, serving cell configuration, or whether uplink transmission includes transform precoding.

[0048] The station selects a first resource set corresponding to a first resource configuration. The station may select the first resource set based on a first message from a base station (BS) and / or knowledge of at least one of the aforementioned domains. In some embodiments, before the station determines which resource set to select, the station may follow a predefined principle to obtain or derive control information about at least one of the aforementioned domains from other configurations through a first message. Then, within the selected resource set, the station determines the actual resources for transmitting channels or signals from a plurality of resources in the selected first resource set based on a second message from the BS and / or an implicit mapping from one or more other PHY channels or signals. Then, the station occupies the determined actual resources to send or receive the corresponding PHY channel or signal. In some examples, the first message is included in a header field of a received frame (e.g., a downlink frame). The header field may be a media access control (MAC) header or include a portion thereof. In some embodiments, the second message may be included in the same header field as the first message, or in other embodiments, the second message may be included in a header field different from the first message. In other examples, in some implementations, the second message may be received in the same frame as the first message, or in other implementations, the second message may be received in a different frame than the first message.

[0049] In other embodiments, before the site determines which resource set to select, the site may receive a first message to obtain or derive control information related to at least one of the above-mentioned domains from other configurations in accordance with a predetermined principle. In some examples, the first message is included in a header field of a received frame (e.g., a downlink frame). In some embodiments, the first message may be included in the same header field as the first message and the second message, or in other embodiments, the first message may be included in a header field different from the first message and the second message. In other examples, in some embodiments, the first message may be received in the same frame as the first message and the second message, or in other embodiments, the first message may be received in a frame different from the first message and the second message. In some embodiments, each of the first message, the second message, and / or the first message is downlink control information (abbreviated as "DCI"), or is at least included in a portion of the downlink control information. In other embodiments, each of the first message, the second message, and / or the first message is radio resource control configuration signaling (abbreviated as "RRC signaling"), or is at least included in a portion of the radio resource control configuration signaling.

[0050] Figure 4A flow chart of an example process 400 for determining resources from different resource sets configured for different DM-RS mapping types according to one or more embodiments is shown. Figure 2 The process 400 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 400 is not limited to Figure 2 The receiver 220 in the wireless communication device 200 of the wireless communication device 200, and one or more blocks (or operations) of the process 400 can be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein can be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of the process 400 are described herein as occurring serially or linearly. However, multiple blocks of the process 400 can occur in parallel. In addition, the blocks of the process 400 do not need to be performed in the order shown, and / or one or more blocks of the process 400 do not need to be performed and / or can be replaced by other operations.

[0051] Process 400 begins at step 401, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 402, the station determines that the configuration includes a DM-RS mapping type by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes a DM-RS mapping type for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. The received frame may include a PHY channel / signal (e.g., PDSCH, PDCCH). In some embodiments, the DM-RS mapping type is associated with a resource allocation scheduling for downlink transmission. Next, at step 403, the station determines whether the DM-RS mapping type is a PDSCH mapping type A or a PDSCH mapping type B. In other embodiments, the DM-RS mapping type is associated with a resource allocation scheduling for uplink transmission. In this regard, the station may determine whether the DM-RS mapping type is a PUSCH mapping type A or a PUSCH mapping type B. If the DM-RS mapping type is mapping type A, then process 400 proceeds to step 404. Otherwise, process 400 proceeds to step 405 .

[0052] Subsequently, when it is determined that the DM-RS mapping type is mapping type A, at step 404, the site selects a resource set corresponding to the DM-RS mapping type A. At step 405, that is, when it is determined that the DM-RS mapping type is mapping type B, the site selects a resource set corresponding to the DM-RS mapping type B. Next, at step 406, the site determines the actual resources from the selected resource set. In some aspects, the site may perform the selection using an indication included in a second message received from the base station. In other aspects, the site may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 407, the site causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0053] In this embodiment, different resource sets are configured for different DM-RS mapping types (eg, PDSCH / PUSCH mapping types A and B). Figure 4 As depicted, the site may first select a resource set corresponding to the DM-RS mapping type and then determine the actual resources for transmitting the PHY channel or signal. If based on the determined DCI overhead, N resources may be configured for PDSCH mapping type A and type B, respectively. A total of 2N resources may be configured according to this embodiment. In fact, compared to conventional methods (e.g., 4G LTE), this method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and may help achieve much greater flexibility in resource allocation scheduling than conventional methods.

[0054] Figure 5 FIG. 5 is a flowchart of an example process 500 for determining resources from different resource sets configured for different BWP configurations according to one or more embodiments. Figure 2 The process 500 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 500 is not limited to Figure 2The receiver 220 in the wireless communication device 200 of the present invention may be used, and one or more blocks (or operations) of the process 500 may be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein may be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of the process 500 are described herein as occurring serially or linearly. However, multiple blocks of the process 500 may occur in parallel. In addition, the blocks of the process 500 do not need to be performed in the order shown, and / or one or more blocks of the process 500 do not need to be performed and / or may be replaced by other operations.

[0055] Process 500 begins at step 501, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 502, the station determines that the configuration includes a BWP configuration by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes a BWP configuration for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. The received frame may include a PHY channel / signal (e.g., PDSCH, PDCCH). In some embodiments, the BWP configuration is associated with a resource allocation schedule for downlink transmission. Next, at step 503, the station determines whether the BWP configuration is a first BWP configuration (referred to as "BWP 1") or a second BWP configuration (referred to as "BWP 2"). If the BWP configuration is BWP 1, then process 500 proceeds to step 504. Otherwise, process 500 proceeds to step 505.

[0056] Subsequently, when it is determined that the BWP configuration is BWP 1, at step 504, the station selects a resource set corresponding to the BWP 1 configuration. At step 505, that is, when it is determined that the BWP configuration is BWP 2, the station selects a resource set corresponding to the BWP 2 configuration. Next, at step 506, the station determines the actual resources from the selected resource set. In some aspects, the station may perform the selection using an indication included in a second message received from the base station. In other aspects, the station may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 507, the station causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0057] In this embodiment, different resource sets are configured for different BWP configurations (e.g., BWP 1 and BWP 2). Figure 5As depicted, the station may first select a resource set corresponding to a specific BWP configuration and then determine the actual resources for transmitting the PHY channel or signal. If based on the determined DCI overhead, N resources may be configured for BWP 1 and BWP 2, respectively. Similarly, compared to conventional methods (e.g., 4G LTE), this method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and facilitates much greater flexibility in resource allocation scheduling than conventional methods.

[0058] Figure 6 A flow chart of an example process 600 for determining resources from different resource sets configured for different component carrier configurations according to one or more embodiments is shown. Figure 2 The process 600 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 600 is not limited to Figure 2 The receiver 220 in the wireless communication device 200 of the wireless communication device 200, and one or more blocks (or operations) of the process 600 can be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein can be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of the process 600 are described herein as occurring serially or linearly. However, multiple blocks of the process 600 can occur in parallel. In addition, the blocks of the process 600 do not need to be performed in the order shown, and / or one or more blocks of the process 600 do not need to be performed and / or can be replaced by other operations.

[0059] Process 600 begins at step 601, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 602, the station determines that the configuration includes a component carrier configuration by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes a component carrier configuration for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. The received frame may include a PHY channel / signal (e.g., PDSCH, PDCCH). In some embodiments, the component carrier configuration is associated with a resource allocation scheduling for downlink transmission. Next, at step 603, the station determines whether the component carrier configuration is a first component carrier configuration (referred to as "CC1") or a second component carrier configuration (referred to as "CC 2"). If the component carrier configuration is CC 1, then process 600 proceeds to step 604. Otherwise, process 600 proceeds to step 605.

[0060] Subsequently, when it is determined that the component carrier configuration is CC 1, at step 604, the site selects a resource set corresponding to the CC 1 configuration. At step 605, that is, when it is determined that the component carrier configuration is CC 2, the site selects a resource set corresponding to the CC 2 configuration. Next, at step 606, the site determines the actual resources from the selected resource set. In some aspects, the site may perform the selection using an indication included in a second message received from the base station. In other aspects, the site may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 607, the site causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0061] In this embodiment, different resource sets are configured for different component carrier configurations (eg, CC 1 and CC 2). Figure 6 As depicted, the station may first select a resource set corresponding to a specific component carrier configuration and then determine the actual resources for transmitting the PHY channel or signal. If based on the determined DCI overhead, N resources may be configured for CC 1 and CC 2, respectively. Similarly, compared to conventional methods (e.g., 4G LTE), this method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and facilitates much greater flexibility in resource allocation scheduling than conventional methods.

[0062] Figure 7 A flow chart of an example process 700 for determining resources from different resource sets configured for different serving cell configurations according to one or more embodiments is shown. Figure 2 The process 700 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 700 is not limited to Figure 2 The receiver 220 in the wireless communication device 200 of the wireless communication device 200, and one or more blocks (or operations) of the process 700 can be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein can be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of the process 700 are described herein as occurring serially or linearly. However, multiple blocks of the process 700 can occur in parallel. In addition, the blocks of the process 700 do not need to be performed in the order shown, and / or one or more blocks of the process 700 do not need to be performed and / or can be replaced by other operations.

[0063] Process 700 begins at step 701, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 702, the station determines that the configuration includes a serving cell configuration by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes a serving cell configuration for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. The received frame may include a PHY channel / signal (e.g., PDSCH, PDCCH). In some embodiments, the serving cell configuration is associated with a resource allocation scheduling for downlink transmission. Next, at step 703, the station determines whether the serving cell configuration is a first serving cell configuration (referred to as "SCELL 1") or a second serving cell configuration (referred to as "SCELL 2"). If the serving cell configuration is SCELL 1, then process 700 proceeds to step 704. Otherwise, process 700 proceeds to step 705.

[0064] Subsequently, when it is determined that the serving cell configuration is SCELL 1, at step 704, the site selects a resource set corresponding to the SCELL 1 configuration. At step 705, i.e., when it is determined that the serving cell configuration is SCELL 2, the site selects a resource set corresponding to the SCELL 2 configuration. Next, at step 706, the site determines the actual resources from the selected resource set. In some aspects, the site may perform the selection using an indication included in a second message received from the base station. In other aspects, the site may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 707, the site causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0065] In this embodiment, different resource sets are configured for different serving cell configurations (eg, SCELL 1 and SCELL 2). Figure 7 As depicted, the site may first select a resource set corresponding to a specific serving cell configuration and then determine the actual resources for transmission of a PHY channel or signal. If based on the determined DCI overhead, N resources may be configured for SCELL1 and SCELL 2, respectively. Similarly, compared to conventional methods (e.g., 4G LTE), this method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and facilitates much greater flexibility in resource allocation scheduling than conventional methods.

[0066] Figure 8A flow chart of an example process 800 for determining resources from different resource sets configured for different transmission waveforms or multiple access configurations according to one or more embodiments is shown. Figure 2 The process 800 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 800 is not limited to Figure 2 The receiver 220 in the wireless communication device 200 of the present invention may be used, and one or more blocks (or operations) of process 800 may be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein may be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of process 800 are described herein as occurring serially or linearly. However, multiple blocks of process 800 may occur in parallel. In addition, the blocks of process 800 do not need to be performed in the order shown, and / or one or more blocks of process 800 do not need to be performed and / or may be replaced by other operations.

[0067] Process 800 begins at step 801, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 802, the station determines that the configuration includes a transform precoding configuration by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes an indication of whether transform precoding is used in an uplink transmission for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. As used herein, the term "uplink transmission using transform precoding" refers to "discrete Fourier transform spread OFDM (or DFT-s-OFDM)", and the term "uplink transmission without transform precoding" refers to "cyclic prefix OFDM (or CP-OFDM)". Next, at step 803, the station determines whether transform precoding is used in the uplink transmission. If transform precoding is used, then process 800 proceeds to step 804. Otherwise, process 800 proceeds to step 805.

[0068] Subsequently, when it is determined that transform precoding is used in the uplink transmission, at step 804, the station selects a resource set corresponding to the uplink transmission using transform precoding. At step 805, that is, when it is determined that transform precoding is not used in the uplink transmission, the station selects a resource set corresponding to the uplink transmission that does not include transform precoding. Next, at step 806, the station determines the actual resources from the selected resource set. In some aspects, the station may perform the selection using an indication included in a second message received from the base station. In other aspects, the station may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 807, the station causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0069] In this embodiment, different resource sets are configured for different transmission waveforms or multiple access schemes (for example, whether transform precoding is used in uplink transmission). Figure 8 As depicted, a site may first select a resource set corresponding to an uplink transmission using transform precoding (e.g., DFT-s-OFDM) or an uplink transmission not using transform precoding (e.g., CP-OFDM), and then determine actual resources for transmission of a PHY channel or signal. If based on the determined DCI overhead, N resources may be configured separately for uplink transmission using transform precoding or uplink transmission not using transform precoding. Similarly, compared to conventional methods (e.g., 4G LTE), the method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and facilitates much greater flexibility in resource allocation scheduling than conventional methods.

[0070] Fig. 9 A flow chart of an example process 900 for determining resources from different resource sets configured for different CORESET / search space configurations according to one or more embodiments is shown. Figure 2 The process 900 is described with reference to the receiver 220 in the wireless communication device 200. However, the process 900 is not limited to Figure 2The receiver 220 in the wireless communication device 200 of the present invention may be used, and one or more blocks (or operations) of the process 900 may be performed by one or more other components or chips in the wireless communication device 200. The wireless communication device 200 is also represented as an exemplary device, and the operations described herein may be performed by any suitable device such as one or more of the wireless communication devices 118-132. In addition, for illustrative purposes, the blocks of the process 900 are described herein as occurring serially or linearly. However, multiple blocks of the process 900 may occur in parallel. In addition, the blocks of the process 900 do not need to be performed in the order shown, and / or one or more blocks of the process 900 do not need to be performed and / or may be replaced by other operations.

[0071] Process 900 begins at step 901, where a station (e.g., 128, 200) obtains a configuration associated with a PHY channel. Next, at step 902, the station determines that the configuration includes a CORESET / search space configuration by receiving a message from a base station (e.g., 116), the message indicating that the received frame includes a CORESET / search space configuration for resource allocation scheduling. In some aspects, the received frame is a downlink frame associated with a downlink transmission of the base station. The received frame may include a PHY channel / signal (e.g., PDSCH, PDCCH). In some embodiments, the CORESET / search space configuration is associated with a resource allocation schedule for downlink transmission. Next, at step 903, the station determines whether the received frame is configured with a first CORESET / search space configuration or a second CORESET / search space configuration. In some examples, the station also determines a periodic configuration and / or a time position associated with the CORESET / search space configuration. If the received frame is configured with a first CORESET / search space configuration, then process 900 proceeds to step 904. Otherwise, process 900 proceeds to step 905 .

[0072] Subsequently, when it is determined that the received frame is configured with a first CORESET / search space configuration, at step 904, the station selects a resource set corresponding to the first CORESET / search space configuration. At step 905, i.e., when it is determined that the received frame is configured with a second CORESET / search space configuration, the station selects a resource set corresponding to the second CORESET / search space configuration. Next, at step 906, the station determines the actual resources from the selected resource set. In some aspects, the station may perform the selection using an indication included in a second message received from the base station. In other aspects, the station may perform the selection based on an implicit mapping of other PHY channels or signals to one or more resources in the selected resource set, so that unmapped resources can be derived. Subsequently, at step 907, the station causes its transceiver (e.g., 205), for example, to receive a PDSCH signal or send a PUSCH signal on the determined actual resources.

[0073] In this embodiment, different resource sets are configured for different CORESET / search space configurations (e.g., their periodic configuration and / or time location). Fig. 9 As depicted, the station may first select a resource set corresponding to a specific CORESET / search space configuration and then determine the actual resources for transmission of the PHY channel or signal. If based on the determined DCI overhead, N resources may be configured for the first CORESET / search space configuration and the second CORESET / search space configuration, respectively. Similarly, compared to conventional methods (e.g., 4G LTE), this method may double the number of candidate resources available for resource allocation scheduling without any additional PHY signaling overhead, and facilitates much greater flexibility in resource allocation scheduling than conventional methods.

[0074] Fig.10 An electronic system 1000 that can be used to implement one or more embodiments of the present technology is conceptually shown. For example, the electronic system 1000 can be a network device, a media converter, a desktop computer, a laptop computer, a tablet computer, a server, a switch, a router, a base station, a receiver, a telephone, or any general electronic device that transmits signals over a network. Such an electronic system 1000 includes various types of computer-readable media and interfaces for various other types of computer-readable media. In one or more embodiments, the electronic system 1000 is or includes one or more of the wireless communication devices 118-132. The electronic system 1000 includes a bus 1008, one or more processing units 1012, a system memory 1004, a read-only memory (ROM) 1010, a permanent storage device 1002, an input device interface 1014, an output device interface 1006, and a network interface 1016, or subsets and variants thereof.

[0075] The bus 1008 generally represents all system buses, peripheral busses, and chipset buses that communicatively connect the numerous internal devices of the electronic system 1000. In one or more implementations, the bus 1008 communicatively connects one or more processing units 1012 with the ROM 1010, the system memory 1004, and the permanent storage device 1002. The one or more processing units 1012 retrieve instructions to be executed and data to be processed from these various storage units to perform the processes of the present disclosure. In different implementations, the one or more processing units 1012 can be a single processor or a multi-core processor.

[0076] ROM 1010 stores static data and instructions required by one or more processing units 1012 and other modules of the electronic system. On the other hand, permanent storage device 1002 is a read-write memory device. Permanent storage device 1002 is a non-volatile storage unit that stores instructions and data even when electronic system 1000 is turned off. One or more embodiments of the present disclosure use a mass storage device (such as a magnetic disk or optical disk and its corresponding magnetic disk drive) as permanent storage device 1002.

[0077] Other embodiments use removable storage devices (e.g., floppy disks, flash drives, and their corresponding disk drives) as permanent storage devices 1002. Like permanent storage devices 1002, system memory 1004 is a read-write memory device. However, unlike permanent storage devices 1002, system memory 1004 is a volatile read-write memory such as random access memory. System memory 1004 stores any instructions and data required by one or more processing units 1012 to operate. In one or more embodiments, the processes of the present disclosure are stored in system memory 1004, permanent storage devices 1002, and / or ROM 1010. One or more processing units 1012 retrieve instructions to be executed and data to be processed from these various storage units to perform the processes of one or more embodiments.

[0078] The bus 1008 is also connected to an input device interface 1014 and an output device interface 1006. The input device interface 1014 enables a user to convey information and select commands to the electronic system. The input device used with the input device interface 1014, for example, includes an alphanumeric keyboard and an indicating device (also referred to as a "cursor control device"). The output device interface 1006, for example, enables the display of an image generated by the electronic system 1000. The output device used with the output device interface 1006, for example, includes a printer and a display device, and the display device is, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a flexible display, a flat panel display, a solid-state display, a projector, or any other device for outputting information. In one or more embodiments, a device that acts as both an input device and an output device is included, such as a touch screen. In these embodiments, the feedback provided to the user can be any form of sensory feedback such as visual feedback, auditory feedback, or tactile feedback, and the input from the user can be received in any form including sound, voice, or tactile input.

[0079] Finally, if Fig.10 As shown, bus 1008 also couples electronic system 1000 to one or more networks (not shown) via one or more network interfaces 1016. In this manner, the computer may be part of one or more computer networks, such as a local area network ("LAN"), a wide area network ("WAN"), or an intranet or a network of networks, such as the Internet. Any or all components of electronic system 1000 may be used in combination with the present disclosure.
