[0028] The following description, with reference to the accompanying drawings, illustrates various exemplary arrangements of this solution to enable those skilled in the art to create and use it. As will be apparent to those skilled in the art, various changes or modifications can be made to the examples described herein without departing from the scope of this solution after reading this document. Therefore, this solution is not limited to the exemplary arrangements and applications described and illustrated herein. Furthermore, the specific order or hierarchy of steps in the methods disclosed herein is merely an example method. Based on design preferences, the specific order or hierarchy of steps in the disclosed methods or processes can be rearranged while remaining within the scope of this solution. Therefore, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or actions in an exemplary order, and unless otherwise expressly stated, this solution is not limited to the specific order or hierarchy presented.

[0029] Some legacy UEs that do not support comb offset or cyclic shift hopping, as well as newer UEs that support comb offset and cyclic shift hopping, can coexist within a cell, with the legacy and newer UEs occupying two corresponding non-overlapping subsets of comb offset / cyclic shift to maintain orthogonality between legacy and newer Sounding Reference Signal (SRS) ports. In other words, comb offset / cyclic shift hopping can be restricted to a subset of comb offset / cyclic shift. The arrangements disclosed herein relate to systems, methods, non-transitory computer-readable media, and apparatuses for configuring a subset of comb offset / cyclic shift and implementing comb offset / cyclic shift hopping when that subset is configured.

[0030] Figure 1 An example CJT-supporting wireless communication system 100 is illustrated according to various arrangements. In the wireless communication system 100, network-side communication nodes, network devices, or base stations (BSs) may include one or more of the following: next-generation node B (gNB), E-Utran node B (also known as evolved node B, eNodeB, or eNB), picocell, femtocell, transmit / receive point (TRP), access point (AP), node, etc. Terminal-side nodes or user equipment (UEs) may include long-range communication systems (such as mobile devices, smartphones, personal digital assistants (PDAs), tablets, laptops) or short-range communication systems (such as wearable devices, vehicles with vehicle communication systems, etc.). As shown, system 100 includes BSs 110, 120, and 130 and UEs 140 and 150. In some arrangements, BSs 110, 120, and 130 may be referred to as wireless communication nodes, and UEs 140 and 150 may be referred to as wireless communication devices.

[0031] like Figure 1 As shown, BS110 (e.g., a network device) can provide wireless communication services to UEs within a cell defined by a first boundary 112 and a second boundary 114, where the second boundary 114 encloses a larger area than the first boundary 112. UE 140 is located within the first boundary 112, and UE 150 is located between the first boundary 112 and the second boundary 114 (within the second boundary 114, but not within the first boundary 112). The area between the first boundary 112 and the second boundary 114 is an edge cell. Compared to a UE located within the first boundary 112 (e.g., UE 140), a UE located in an edge cell (e.g., UE 150) experiences reduced service (e.g., signal strength). UE 140 can communicate with BS110 via a first communication channel. Similarly, UE 150 can communicate with BS110 via a second communication channel.

[0032] BS120 can provide wireless communication services to UEs within a cell defined by a first boundary 122 and a second boundary 124, where the second boundary 124 encloses a larger area than the first boundary 122. UE 150 is located between the first boundary 122 and the second boundary 124 (within the second boundary 124, but not within the first boundary 122). The area between the first boundary 122 and the second boundary 124 is an edge cell. Similarly, UEs located in edge cells experience reduced service (e.g., signal strength) compared to UEs located within the first boundary 122. UE 150 can communicate with BS120 via a third communication channel.

[0033] BS130 can provide wireless communication services to UEs within a cell defined by a first boundary 132 and a second boundary 134, where the second boundary 134 encloses a larger area than the first boundary 132. The area between the first boundary 132 and the second boundary 134 is an edge cell. Similarly, UEs located in edge cells experience reduced service (e.g., signal strength) compared to UEs located within the first boundary 132.

[0034] TDD CJT was introduced in 5G Advanced New Radio (NR) to improve the downlink capabilities of cell-edge UEs (e.g., UE 150 on BS110). In TDD CJT, a CJT UE (e.g., UE 150) transmits SRS to multiple CJT TRPs (e.g., BS110 and 120). The BS can implement downlink CJT based on a precoder derived from the received SRS. From the TRP's perspective, a CJT TRP (e.g., BS110) receives SRS transmitted from its own serving UE (e.g., UE 140) and the serving UE of another TRP (CJT UE, e.g., UE 150 serving BS120). Due to the SRS resource allocation for each TRP, SRS transmitted from serving UEs of different TRPs may be non-orthogonal and interfere with each other. To randomize interference and improve CJT performance, in addition to frequency hopping and group / sequence hopping, comb offset hopping and cyclic shift hopping of SRS can also be used. The newly introduced comb offset / cyclic shift jump can be restricted to a subset of comb offset / cyclic shift to support the coexistence of traditional UEs and new UEs within a cell.

[0035] As used in this document, a traditional UE (and its SRS resources and SRS ports) refers to a UE that does not support comb offset / cyclic shift hop. A new UE (and its SRS resources and SRS ports) refers to a UE that supports comb offset / cyclic shift hop.

[0036] Figure 2 Block diagrams are shown of an example BS202 (e.g., a network device) and an example UE 204 according to some arrangement. BS202 is an example of BS110, 120, and 130. UE 204 is an example of UE 140 and 150.

[0037] BS202 includes a BS transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218. Each module is coupled and interconnected with each other via a data communication bus 220 as needed. UE 204 includes a UE transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236. Each module is coupled and interconnected with each other via a data communication bus 240 as needed. BS202 communicates with UE 204 via a communication channel, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0038] BS202 and UE 204 may also include Figure 2 Any number of other modules besides those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the implementations disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, the various illustrative components, blocks, modules, circuits, and steps are generally described according to their functionality. Whether such functionality is implemented in hardware, firmware, or software can depend on the specific application and design constraints imposed on the system as a whole. Those skilled in the art can implement such functionality appropriately for each specific application; however, such implementation decisions should not be construed as limiting the scope of this document.

[0039] According to some implementations, UE transceiver 230 may be referred to herein as a UL transceiver, which includes a radio frequency (RF) transmitter and an RF receiver, each of which includes circuitry coupled to antenna 232. A duplex switch (not shown) may alternatively couple the UL transmitter or receiver to the UL antenna in a time-duplex manner. Similarly, according to some implementations, BS transceiver 210 may be referred herein as a downlink (DL) transceiver, which includes an RF transmitter and an RF receiver, each of which includes circuitry coupled to antenna 212. A DL duplex switch may alternatively couple the DL transmitter or receiver to DL antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 may be time-coordinated such that the UL receiver circuitry is coupled to UL antenna 232 for reception of transmissions over a wireless transmission link while the DL transmitter is coupled to DL antenna 212. In some implementations, there is tight time synchronization with a minimum guard time between changes in duplex direction.

[0040] UE transceiver 230 and BS transceiver 210 are configured to communicate via a wireless data communication link and cooperate with RF antenna arrangements 212 / 232 in an appropriate configuration capable of supporting specific wireless communication protocols and modulation schemes. In some implementations, UE transceiver 230 and BS transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G and 6G standards. However, it should be understood that this document is not necessarily limited to application to specific standards and related protocols. Rather, UE transceiver 230 and BS transceiver 210 can be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0041] Processor modules 214 and 236 can be implemented or carried out using a general-purpose processor, content-addressable memory, digital signal processor, application-specific integrated circuit, field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this way, the processor can be implemented as a microprocessor, controller, microcontroller, state machine, etc. The processor can also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.

[0042] Furthermore, the methods described in conjunction with the implementations disclosed herein can be implemented directly in hardware, firmware, in software modules executed by processor modules 214 and 236 respectively, or in any practical combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this respect, memory modules 216 and 234 can be coupled to processor modules 210 and 230 respectively, such that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234 respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some implementations, each of memory modules 216 and 234 may include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230 respectively. Memory modules 216 and 234 may each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.

[0043] Network communication module 218 represents the hardware, software, firmware, processing logic, and / or other components of BS 202 used to enable bidirectional communication between BS transceiver 210 and other network components and communication nodes configured to communicate with BS 202. For example, network communication module 218 may be configured to support Internet or WiMAX services. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface, enabling BS transceiver 210 to communicate with conventional Ethernet-based computer networks. In this way, network communication module 218 may include a physical interface for connection to a computer network (e.g., a Mobile Switching Center (MSC)).

[0044] The terms “configured for,” “configured to,” and variations thereof, used in connection with the specified operation or function, refer to devices, components, circuits, structures, machines, signals, etc., that are physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0045] In some arrangements where comb offset / cyclic shift skipping is enabled for SRS resources, the comb offset / cyclic shift of each SRS port associated with the SRS resource is determined by the timing of the transmission timing at each transmission opportunity. Figure 3 This is a flowchart illustrating an example method 300 for determining comb offset and cyclic shift hop for SRS ports of SRS resources according to various arrangements. Method 300 can be performed using a system 100 including a UE 150 and a BS 120 (e.g., a network device). In some examples, the BS 120 sends an indication to the UE 150, and the UE 150 receives from the BS 120, that at least one of comb offset or cyclic shift hop is enabled. This indication can be provided via appropriate signaling or parameters (including higher-layer parameters).

[0046] In some examples, examples of higher-layer parameters include Radio Resource Control (RRC) parameters, Radio Resource Management (RRM) parameters, Radio Resource Allocation (RRA) parameters, Downlink Control Information (DCI), or Physical Downlink Control Channel (PDCCH).

[0047] BS120 sends at least one parameter to UE 150 for configuring or determining one or more comb offsets and / or one or more cyclic shifts for controlling the SRS port. For example, at 310, BS120 sends to UE 150 at least one of a first parameter indicating a subset of comb offsets or a second parameter indicating a subset of cyclic shifts. At 320, UE 150 receives from BS120 at least one of the first parameter indicating a subset of comb offsets or a second parameter indicating a subset of cyclic shifts. Each of the at least one first parameter and each of the at least one second parameter can be provided via appropriate signaling or parameters (including higher-layer parameters). The comb offset used for transmitting the SRS is limited to a subset of comb offsets. The cyclic shift used for transmitting the SRS is limited to a subset of cyclic shifts. In some examples, BS120 sends to and UE 150 receives from BS120 at least one parameter indicating an initialization identifier (ID) for a pseudo-random sequence c(i).

[0048] At 330, UE 150 determines at least one of the comb offset or cyclic shift for each SRS port associated with the SRS resource, based on the transmission time and at least one of the first or second parameters. The SRS resource may be associated with multiple SRS ports. The SRS resource may include time-domain resources and frequency-domain resources.

[0049] At 340, UE 150 sends an SRS to BS 120 based on at least one of a comb offset or a cyclic shift. At 350, BS 120 receives the SRS sent based on at least one of a comb offset or a cyclic shift.

[0050] In some examples, legacy and new SRS resources (e.g., SRS resources used by legacy and new UEs) are scheduled on overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbols. Legacy and new SRS resources are configured with the same transport comb. In examples where comb offset and / or cyclic shift hopping is not enabled, legacy and new SRS resources do not occupy the same cyclic shift on the same comb offset. Such configuration can be enabled by configuration sent to the UE's BS or otherwise provided.

[0051] In some configurations, for SRS resources configured with comb offset hopping, during SRS transmission, SRS port p i comb offset Determined by at least one of the following: SRS port p i Initial comb offset (It is determined by the higher-level parameter transmissionComb), the timing of SRS transmission (in units of symbols, R symbols, time slots, ms, etc.), the pseudo-random sequence c(i), one or more parameters indicating a subset of the comb offset, etc., etc. In some examples, the comb offset of each SRS port associated with the SRS resource is determined based on at least one of the following: the initial comb offset (e.g., The transmission timing of the SRS is the transmission time, the pseudo-random sequence, or the first parameter indicating the comb offset subset. As used herein, the time unit refers to a unit of time or a measurement of time, such as sub-symbol, symbol, time slot, subframe, frame, transmission timing, etc.

[0052] The comb offset subset can be indicated by the high-level parameter `transmissionComb` and one of the following: comb offset jump offset set. And the comb offset jump granularity X. In some examples, the first parameter includes the parameter transmissionComb, which indicates the maximum number of cyclic shifts and transmission combs for the SRS resource, as well as the initial comb offset and initial cyclic shift for each SRS port associated with the SRS resource. In some examples, the first parameter includes the comb offset jump offset set. Or one of the comb offset jump granularities X.

[0053] In some examples, Including L TC Each comb offset jump offset, where L TC ≤K TC K TC These are parameters in the transmissionComb that correspond to the transmission comb. Each comb offset jump offset in It is to satisfy Integers. For example, for K TC =4, In some examples, the comb offset jump offset set includes a certain number (e.g., L) TC (Number) comb offset jump offsets, the number of which is less than or equal to the number of transport combs, and each comb offset jump offset in the comb offset jump offsets is an integer greater than or equal to 0 and less than or equal to the number of transport combs minus 1.

[0054] In some examples, It can be composed of length K TC It is represented by a bitmap. In some examples where the i-th element in the bitmap is 1, the value i-1 is included. In some examples where the i-th element in the bitmap is 0, the value i-1 is not included. In the middle. For example, for (where K)TC =4) can be indicated by a bitmap {1, 0, 1, 1}. In some examples, UE 150 receives from BS120 (e.g., a network device) a bitmap indicating the comb offset hop offset set, the length of which is equal to the transmission comb. In some examples, the comb offset subset is equivalent to the entire comb offset set.

[0055] In some examples, the comb offset jump granularity is an integer greater than or equal to 1. The comb offset jump granularity is selected from a set of candidate values. The set of candidate values ​​is determined based on the transport comb. For example, the candidate values ​​for X are {1, 2, 4, 8}. For K TC =2, and the candidate values ​​for X include {1, 2}. For K TC =4, and the candidate values ​​for X include {1, 2, 4}. For K TC =8, and candidate values ​​for X include {1, 2, 4, 8}. In some examples where X = 1, the subset of comb offsets is equivalent to the entire set of comb offsets.

[0056] X can be a configurable higher-level parameter, which can be implicitly configured and indicated by the higher-level parameter `transmissionComb`, or it can be a fixed / default parameter. In some examples, the comb offset jump offset set or comb offset jump granularity is configured to the UE 150 by the BS120 using at least one higher-level parameter. In some examples, the comb offset jump offset set or comb offset jump granularity is indicated using the parameter `transmissionComb`. In some examples, the comb offset jump offset set or comb offset jump granularity is a fixed parameter.

[0057] exist In some examples where X uses higher-layer parameters for configuration, the higher-layer parameters are configured by the base station based on SRS resources. In some examples, the comb offset hop offset set or comb offset hop granularity is configured by the BS120 to the UE 150 using at least one higher-layer parameter. At least one higher-layer parameter is configured by the BS120 for each of the multiple SRS resources.

[0058] exist Or X is configured using higher-level parameters in some examples, The configuration or selection of X is based on at least one of the following: the high-level parameter transmissionComb and the comb offset / circular shift occupied by conventional SRS resources on the overlapping OFDM symbols. The principle behind the configuration or selection of X is to guarantee the comb offset subset indicated by transmissionComb, and One of X does not overlap with a comb offset occupied by a legacy SRS resource at the same cyclic shift on the same OFDM symbol. In some examples, the comb offset skip offset set or comb offset skip granularity is configured to the UE 150 by the BS120 using at least one higher-layer parameter. The comb offset skip offset set or comb offset skip granularity is determined by the BS120 based on at least one of the following: the parameter transmissionComb; or at least one comb offset or at least one cyclic shift occupied by at least one legacy SRS resource on at least one overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbol.

The comb offset jump offset set is determined according to expression (1), and the comb offset jump granularity is determined according to expression (2).

[0064] In some arrangements, multiple new SRS resources are scheduled on overlapping OFDM symbols and overlapping frequency ranges (e.g., resource blocks (RBs)) to maintain orthogonality between the new SRS ports, and different new SRS resources can be configured with different comb offset subsets. In some examples, multiple new SRS resources are scheduled on overlapping OFDM symbols. The new SRS ports are orthogonal to each other. Different SRS resources among the multiple new SRS resources are configured with different comb offset subsets.

[0065] In some arrangements, multiple new SRS resources are scheduled on overlapping OFDM symbols and overlapping frequency ranges (e.g., RBs) to maintain orthogonality between the new SRS ports, and different new SRS resources can be configured with the same comb offset subset. It is expected that the same c(i) initialization ID will be applied to all new SRS resources. In some examples, multiple new SRS resources are scheduled on overlapping orthogonal OFDM symbols. The new SRS ports are orthogonal to each other. Different SRS resources among the multiple new SRS resources are configured with the same comb offset subset. The same pseudo-random sequence c(i) initialization ID is applied to all SRS resources among the multiple new SRS resources.

To clearly illustrate this interchangeability of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally according to their functionality. Whether such functionality is implemented in hardware, firmware, software, or a combination of these technologies depends on the specific application and the design constraints imposed on the system as a whole. Those skilled in the art can implement the described functionality in various ways for each specific application, but such implementation decisions will not lead to a departure from the scope of this document.

[0153] Furthermore, those skilled in the art will understand that the various illustrative logic blocks, modules, devices, components, and circuits described herein can be implemented within or executed by integrated circuits (ICs), which may include general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, or any combination thereof. Logic blocks, modules, and circuits may also include antennas and / or transceivers for communication with various components within a network or device. A general-purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller, or state machine. The processor may also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other suitable configuration for performing the functions described herein.

[0154] If implemented in software, these functions can be stored as one or more instructions or code on a computer-readable medium. Therefore, the steps of the methods or algorithms disclosed herein can be implemented as software stored on a computer-readable medium. A computer-readable medium includes both computer storage media and communication media, encompassing any medium capable of transferring a computer program or code from one place to another. A storage medium can be any available medium that is accessible to a computer. By way of example and not limitation, such a computer-readable medium can include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code in the form of instructions or data structures and is accessible to a computer.

[0155] In this document, the term "module" as used herein refers to software, firmware, hardware, and any combination of these elements used to perform the relevant functions described herein. Furthermore, for the purposes of discussion, various modules are described as discrete modules; however, as will be apparent to those skilled in the art, two or more modules may be combined to form a single module that performs the associated functions according to the arrangement of this solution.

[0156] Furthermore, memory or other storage devices and communication components may be employed in the arrangement of this solution. It should be understood that, for clarity, the above description has referenced different functional units and processors in describing the arrangement of this solution. However, it will be apparent that any suitable functional distribution among different functional units, processing logic elements, or domains can be used without departing from this solution. For example, functions illustrated as being performed by a separate processing logic element or controller can be performed by the same processing logic element or controller. Therefore, references to specific functional units are merely references to the appropriate manner of providing the described functions and do not represent a strict logical or physical structure or organization.

[0157] Various modifications to the implementations described herein will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other implementations without departing from the scope thereof. Therefore, this document is not intended to be limited to the implementations shown herein, but should be accorded the widest scope consistent with the novel features and principles disclosed herein, as set forth in the following claims.
