Description

Technical Field

[0001] The present disclosure relates to communication devices, infrastructure equipment and methods for more efficient operation of communication devices and infrastructure equipment in a wireless communication network.

[0002] This application claims the Paris Convention priority of European Patent Application No. 22187188.2 filed on July 27, 2022, the contents of which are incorporated herein by reference. Background Art

[0003] The "background" description provided herein is for the purpose of generally presenting the context of the present disclosure. The work performed by the presently designated inventors described in this background section, and aspects that may not qualify as prior art at the time of filing, are not admitted, either explicitly or implicitly, to be prior art to the present disclosure.

[0004] Previous generation mobile telecommunication systems, such as those based on the UMTS and Long Term Evolution (LTE) architectures defined by 3GPP, are able to support a wider range of services than the simple voice and messaging services provided by previous generation mobile telecommunication systems. For example, using the improved radio interface and enhanced data rates provided by LTE systems, users are able to enjoy high data rate applications, such as mobile video streaming and mobile video conferencing, which were previously only available via fixed line data connections. Therefore, there is a strong demand to deploy such networks, and it is expected that the coverage areas of these networks (i.e., the geographic locations where the networks can be accessed) will continue to increase rapidly.

[0005] It is expected that current and future wireless communication networks will routinely and efficiently support communications for an ever-increasing range of devices that are associated with and are optimized to support a wider range of data service profiles and types than existing systems. For example, it is expected that future wireless communication networks will efficiently support communications with devices including reduced complexity devices, machine type communication (MTC) devices, high-resolution video displays, virtual reality headsets, extended reality (XR), etc. Some of these different types of devices may be deployed in very large numbers, such as low-complexity devices used to support the "Internet of Things", and may generally be associated with the transmission of relatively small amounts of data with relatively high delay tolerance. Other types of devices (e.g., supporting high-definition video streaming) may be associated with the transmission of relatively large amounts of data with relatively low delay tolerance. Other types of devices, such as for autonomous vehicle communications and for other critical applications, may be characterized by data that should be transmitted over the network with low latency and high reliability. Depending on the application being run, a single device type may also be associated with different service profiles / characteristics. For example, different considerations may apply to effectively support data exchange with a smartphone when the smartphone is running a video streaming application (high downlink data) compared to when the smartphone is running an Internet browsing application (sporadic uplink and downlink data) or when it is used for voice communications by emergency responders in an emergency situation (data subject to strict reliability and latency requirements).

[0006] In view of this, there is a desire for current wireless communication networks (e.g., those which may be referred to as 5G or New Radio (NR) systems / new radio access technology (RAT) systems or indeed future 6G wireless communications) as well as future iterations / releases of existing systems to effectively support connectivity for a wide range of devices associated with different applications and different characteristic data service profiles and requirements.

[0007] One example of a new service is called an ultra-reliable low-latency communication (URLLC) service, which, as the name implies, requires the transmission of data units or packets with high reliability and low communication latency. Another example of a new service is an enhanced mobile broadband (eMBB) service, which is characterized by the requirement to support high capacity of up to 20Gb / s. Therefore, URLLC and eMBB type services represent challenging examples for both LTE type communication systems and 5G / NR communication systems.

[0008] 5G NR has continued to evolve and the current work plan includes 5G-NR-Advanced, where some further enhancements are expected, especially to support new use cases / scenarios with higher requirements. The desire to support these new use cases and scenarios gives rise to new challenges for efficiently handling communications in wireless communication systems that need to be addressed. Summary of the invention

[0009] The present disclosure may help solve or alleviate at least some of the above-mentioned problems.

[0010] Embodiments of the present technology may provide a method for operating a communication device. The method includes receiving a control signal from a wireless communication network, the control signal indicating a resource allocation, the resource allocation being used for the communication device to transmit an uplink transmission to the wireless communication network or receive a downlink transmission from the wireless communication network within a set of consecutive resource units of a wireless radio interface, wherein the set of consecutive resource units includes one or more uplink frequency sets and one or more downlink frequency sets, each uplink frequency set includes a plurality of uplink resource units, each downlink frequency set includes a plurality of downlink resource units, and wherein the resource allocation indicates at least one of the uplink resource units of the first uplink frequency set in the uplink frequency set used for the uplink transmission, or for the downlink transmission. at least one of the downlink resource units of the first downlink frequency set in the downlink frequency set for uplink transmission; receiving a copy indication from the wireless communication network, the copy indication being used to indicate that: the resource allocation for the uplink transmission in the first uplink frequency set is repeated in one or more other uplink frequency sets and / or in the first uplink frequency set, or the resource allocation for the downlink transmission in the first downlink frequency set is repeated in one or more other downlink frequency sets and / or in the first downlink frequency set; and, based on the resource allocation and the copy indication, transmitting the uplink transmission to the wireless communication network or receiving the downlink transmission from the wireless communication network.

[0036] Long Term Evolution Advanced Radio Access Technology (4G)

[0037] Figure 1 A schematic diagram is provided showing some basic functions of a mobile telecommunication network / system 6 that typically operates according to LTE principles, but which may also support other radio access technologies, and which may be suitable for implementing embodiments of the present disclosure as described herein. Figure 1 Certain aspects of the various elements and their corresponding modes of operation are well known and defined in relevant standards managed by the 3GPP (RTM) body and are also described in a number of books on the subject, for example, Holma H. ​​and Toskala A [1]. It should be understood that operational aspects of the telecommunications network discussed herein that are not specifically described (e.g., relating to specific communication protocols and physical channels used for communication between different elements) may be implemented in accordance with any known techniques, for example, in accordance with relevant standards and known proposed amendments and supplements to relevant standards.

[0038] The network 6 comprises a plurality of base stations 1 connected to a core network 2. Each base station provides a coverage area 3 (ie a cell) within which data can be communicated to and from a communication device 4. Figure 1Although shown as a single entity in the figure, those skilled in the art will appreciate that some functions of a base station may be performed by different interconnected elements such as antennas (or antennae), remote radio heads, amplifiers, etc. Collectively, one or more base stations may form a radio access network.

[0039] Data is transmitted from the base station 1 to the communication device 4 within its corresponding coverage area 3 via a radio downlink. Data is transmitted from the communication device 4 to the base station 1 via a radio uplink. The core network 2 routes data to and from the communication device 4 via the corresponding base station 1, and provides functions such as authentication, mobility management, charging, etc. The terminal device may also be referred to as a mobile station, user equipment (UE), user terminal, mobile radio, communication device, etc. The services provided by the core network 2 may include a connection to the Internet or to an external telephone service. The core network 2 may further track the location of the communication device 4 so that it can effectively contact (i.e., page) the communication device 4 for transmitting downlink data to the communication device 4.

[0040] Base stations, as examples of network infrastructure equipment, may also be referred to as transceiver stations, Node Bs, e-Node Bs, eNBs, g-Node Bs, gNBs, etc. In this regard, different terms are often associated with different generations of wireless telecommunication systems for elements that provide broadly comparable functionality. However, exemplary embodiments of the present disclosure may be implemented equally in different generations of wireless telecommunication systems, and for simplicity, certain terms may be used regardless of the underlying network architecture. That is, the use of particular terms associated with certain exemplary implementations is not intended to indicate that these implementations are limited to the particular generation of networks to which the particular terms may be most associated.

[0041] New Radio Access Technology (5G)

[0042] It is expected that systems incorporating NR technology will support different services (or service types), which may be characterized by different requirements for latency, data rate, and / or reliability. For example, enhanced mobile broadband (eMBB) services are characterized by requirements to support high capacity up to 20 Gb / s. Requirements for ultra-reliable and low-latency communications (URLLC) services are for 1-10 Gb / s of data within 1 ms. -5 A reliability of (99.999%) or higher (99.9999%) [2] for one transmission of a 32-byte packet from the radio protocol layer 2 / 3 SDU entry point to the radio protocol layer 2 / 3 SDU exit point of the radio interface.

[0043] Massive machine type communication (mMTC) is another example of a service that can be supported by NR-based communication networks. In addition, the system can be expected to support further enhancements related to the Industrial Internet of Things (IIoT) to support services with new requirements for high availability, high reliability, low latency, and in some cases high precision positioning.

[0044] exist Figure 2 An exemplary configuration of a wireless communication network is shown in FIG, which uses some of the terms proposed and used for NR and 5G. Figure 2 In the figure, a plurality of transmission and reception points (TRPs) 10 are connected to distributed control units (DUs) 41, 42 via connection interfaces represented by lines 16. Each TRP 10 is arranged to transmit and receive signals within a radio frequency bandwidth available for the wireless communication network via a wireless access interface. Therefore, within the range of radio communication via the wireless access interface, each TRP 10 forms a cell of the wireless communication network, as represented by circle 12. Therefore, a wireless communication device 14 within the radio communication range provided by the cell 12 can transmit and receive signals to and from the TRP 10 via the wireless access interface. Each of the distributed units 41, 42 is connected to a central unit (CU) 40 (which may be referred to as a control node) via an interface 46. The central unit 40 is then connected to a core network 20, which may contain all other functions required for transmitting data to and from the wireless communication device, and the core network 20 may be connected to other networks 30.

[0045] Figure 2 The elements of the wireless access network shown in FIG. 1 may be arranged in a manner similar to that described with respect to FIG. Figure 1 The examples described above operate in a manner consistent with the respective elements of the LTE network. It should be appreciated that Figure 2 The operational aspects of the telecommunications network represented in and the operational aspects of other networks discussed herein according to embodiments of the present disclosure (not specifically described (e.g., with respect to specific communication protocols and physical channels used for communication between different elements)) may be implemented according to any known technology, for example, according to currently used methods for implementing such operational aspects of wireless telecommunications systems (e.g., in accordance with relevant standards).

[0046] Figure 2The TRP 10 may partially have functionality corresponding to a base station or eNodeB of an LTE network. Similarly, the communication device 14 may have functionality corresponding to a communication device 4 known for operating with an LTE network. Therefore, it should be understood that operational aspects of the new RAT network (e.g., related to specific communication protocols and physical channels used for communication between different elements) may be different from those known from LTE or other known mobile telecommunication standards. However, it should also be understood that each core network component, base station, and communication device of the new RAT network is similar in function to the core network component, base station, and communication device of the LTE wireless communication network, respectively.

[0047] In terms of a wide range of top-level features, it can be broadly considered that the connection to Figure 2 The core network 20 of the new RAT telecommunication system represented in Figure 1 The core network 2 shown in FIG. 1 corresponds to the core network 2 shown in FIG. 1 , and the corresponding central unit 40 and its associated distributed unit / TRP 10 can be broadly considered to provide corresponding Figure 1 The term network infrastructure equipment / access node may be used to cover both these elements of the wireless communication system and the more conventional base station type elements. Depending on the application to be implemented, the responsibility for scheduling transmissions scheduled over the radio interface between the various distributed units and the communication devices may lie with the control node / central unit and / or the distributed units / TRP. Figure 2 1 shows a communication device 14 within the coverage area of ​​the first communication cell 12. Thus, the communication device 14 can exchange signaling with the first central unit 40 in the first communication cell 12 via one of the distributed units / TRPs 10 associated with the first communication cell 12.

[0048] It should also be understood that Figure 2 It only represents one example of the proposed architecture for a new RAT-based telecommunication system, wherein the method according to the principles described herein may be employed and the functionalities disclosed herein may also be applied to wireless telecommunication systems having different architectures.

[0049] Therefore, according to various architectures (such as Figure 1 and Figure 2), certain embodiments of the present disclosure as discussed herein may be implemented in a wireless telecommunications system / network. Therefore, it should be appreciated that the specific wireless telecommunications architecture in any given implementation is not of primary significance to the principles described herein. In this regard, certain embodiments of the present disclosure may be generally described in the context of communications between network infrastructure equipment / access nodes and communication devices, wherein the specific characteristics of the network infrastructure equipment / access nodes and communication devices will depend on the network infrastructure to be implemented. For example, in some cases, the network infrastructure equipment / access nodes may include base stations, such as Figure 1 The LTE type base station 1 shown is suitable for providing functions according to the principles described herein, and in other examples, the network infrastructure equipment may include Figure 2 A control unit / control node 40 and / or a TRP 10 of the kind shown in FIG. 1 is adapted to provide functionality according to the principles described herein.

[0050] Figure 2 A more detailed diagram of some components of the network is shown in Figure 3 Provided. Figure 3 As a simplified representation, Figure 2 The TRP 10 shown in FIG. 1 includes a wireless transmitter 30, a wireless receiver 32, and a controller or control processor 34, which is operable to control the transmitter 30 and the wireless receiver 32 to transmit and receive radio signals to one or more UEs 14 within the cell 12 formed by the TRP 10. Figure 3 As shown, the exemplary UE 14 is shown to include a corresponding transmitter 49, a receiver 48 and a controller 44, which is configured to control the transmitter 49 and the receiver 48 to transmit signals representing uplink data to the wireless communication network via the wireless access interface formed by TRP10 and to receive downlink data according to conventional operations as signals transmitted by the transmitter 30 and received by the receiver 48.

[0051] Transmitters 30, 49 and receivers 32, 48 (as well as other transmitters, receivers, and transceivers described with respect to the examples and embodiments of the present disclosure) may include radio frequency filters and amplifiers as well as signal processing components and devices to transmit and receive radio signals, for example, in accordance with the 5G / NR standard. Controllers 34, 44 (as well as other controllers described with respect to the examples and embodiments of the present disclosure) may be, for example, a microprocessor, a CPU, or a dedicated chipset configured to execute instructions stored on a computer-readable medium (such as a non-volatile memory). The processing steps described herein may be performed, for example, by a microprocessor in combination with a random access memory, operating according to instructions stored on a computer-readable medium. For ease of representation, the transmitters, receivers, and controllers are illustrated in FIG. Figure 3Schematically shown as separate elements in the figure. However, it will be appreciated that the functionality of these elements may be provided in a variety of different ways, for example, using one or more appropriately programmed programmable computers, or one or more appropriately configured application specific integrated circuits / circuits / chips / chip sets. As will be appreciated, the infrastructure equipment / TRP / base station and the UE / communication device will typically include various other elements associated with their operational functionality.

[0052] like Figure 3 As shown, the TRP 10 also includes a network interface 50 that is connected to the DU 42 via the physical interface 16. Thus, the network interface 50 provides a communication link for data and signaling traffic from the TRP 10 to the core network 20 via the DU 42 and the CU 40.

[0053] The interface 46 between the DU 42 and the CU 40 is called the F1 interface, which can be a physical or logical interface. The F1 interface 46 between the CU and the DU can be operated according to the 3GPP TS 38.470 and 3GPP TS 38.473 specifications, and can be formed by optical fiber or other wired or wireless high-bandwidth connections. In one example, the connection 16 from the TRP 10 to the DU 42 is via optical fiber. The connection between the TRP 10 and the core network 20 can generally be referred to as a backhaul, which includes the interface 16 from the network interface 50 of the TRP 10 to the DU 42 and the F1 interface 46 from the DU 42 to the CU 40.

[0054] Full-duplex time division duplex (FD-TDD)

[0055] NR / 5G networks may use time division duplex (TDD) operation, where an entire frequency band or carrier is switched to downlink or uplink transmission during a time period, and may be switched to the other of the downlink or uplink transmissions at a later time period. Currently, TDD operates in half-duplex mode (HD-TDD), where a gNB or UE may transmit or receive packets at a given time, but not simultaneously. As wireless networks transition from NR to advanced 5G networks, a new feature of such networks is proposed to enhance the duplex operation of time division duplex (TDD) by implementing full-duplex operation in TDD (FD-TDD) [3], [4].

[0056] In FD-TDD, the gNB can transmit and receive data to and from the UE simultaneously on the same frequency band. In addition, depending on the capabilities of the UE, the UE can operate in HD-TDD or FD-TDD mode. For example, when the UE is only capable of supporting HD-TDD, FD-TDD is implemented (simultaneously) at the gNB by scheduling DL transmissions to a first UE and scheduling UL transmissions from a second UE within the same orthogonal frequency division multiplexing (OFDM) symbol. In contrast, when the UE is capable of supporting FD-TDD, FD-TDD is implemented at both the gNB and the UE, where the gNB can schedule the UE simultaneously with DL and UL transmissions within the same OFDM symbol by scheduling DL and UL transmissions at different frequencies (e.g., physical resource blocks (PRBs)) of the system broadband. A UE that supports FD-TDD requires more complex hardware than a UE that only supports HD-TDD. Current 5G network development focuses on implementing FD-TDD at the gNB for UEs operating in HD-TDD mode.

[0057] Motivations for enhancing TDD duplex operation include improvements in system capabilities, reduced latency, and improved uplink coverage. For example, in current HD-TDD systems, OFDM symbols are allocated in a semi-static manner for only DL or UL directions. So, if one direction experiences less or no data, the spare resources cannot be used in the other direction, or at best are underutilized. However, if resources can be used for both DL and UL data (as in FD-TDD), resource utilization in the system can be improved. In addition, in current HD-TDD systems, UEs can receive DL data but cannot transmit UL data at the same time, which results in latency. If the gNB or UE is allowed to transmit and receive data simultaneously (as with FD-TDD), traffic latency will be improved. In addition, when close to the cell edge, UEs are usually limited in UL transmission. If more time domain resources are allocated to UL transmission (e.g., repetition), UE coverage at the cell edge can be improved. If more time resources are allocated to the UL direction, less time resources can be allocated to the DL direction, which can lead to system imbalance. Implementing FD-TDD will help allow UEs to be assigned more UL time resources when needed without sacrificing DL time resources.

[0058] Cross-link Interference (CLI)

[0059] In NR systems, the slot format (i.e., the allocation of DL and UL OFDM symbols in a slot) can be semi-statically or dynamically configured, where each OFDM symbol (OS) in a slot can be configured as downlink (DL), uplink (UL), or flexible (F). OFDM symbols semi-statically configured as flexible can be dynamically indicated as DL, UL, or remain flexible by a dynamic slot format indicator (SFI), which is transmitted in a group common (GC) DCI using DCI format 2_0, where the CRC of the GC-DCI is masked by the SFI-RNTI. Flexible OFDM symbols that remain flexible after an indication from the SFI can be changed to DL symbols or UL symbols by a DL grant or a UL grant, respectively. That is, a DL grant for scheduling a PDSCH that overlaps with a flexible OFDM symbol converts these flexible OFDM symbols to DL, and similarly, a UL grant for scheduling a PUSCH that overlaps with a flexible OFDM symbol converts these flexible OFDM symbols to UL.

[0060] Because each gNB in ​​the network can independently change the configuration of each OFDM symbol, either semi-statically or dynamically, it is possible that in a particular OFDM symbol, one gNB is configured for UL and a neighboring gNB is configured for DL. This causes inter-cell cross-link interference (CLI) between the conflicting gNBs (due to UL / DL symbol collisions for one or more symbols). Inter-cell CLI occurs when a UE's UL transmission interferes with the DL reception of another UE in another cell, or when a gNB's DL transmission interferes with the UL reception of another gNB. That is, inter-cell CLI is caused by misaligned (colliding) slot formats between neighboring cells. Figure 4 An example is shown in FIG. 4 where gNB1 411 and gNB2 412 have synchronized timeslots. In a given timeslot, the timeslot format of gNB1 411 = {D,D,D,D,D,D,D,D,D,U,U,U,U} and the timeslot format of gNB2 412 = {D,D,D,D,D,D,D,D,D,D,U,U,U}, where ‘D’ indicates DL and ‘U’ indicates UL. The inter-cell CLI occurs during the 11th OFDM symbol of the timeslot where gNB1 411 is performing UL and gNB2 412 is performing DL. Specifically, the inter-cell CLI 441 occurs between gNB1 411 and gNB2 412 where the DL transmission 431 of gNB2 412 interferes with the UL reception 432 of gNB1 411. CLI 442 also occurs between UE1 421 and UE2 422 , where UL transmission 432 of UE1 421 interferes with DL reception 431 of UE2 422 .

[0061] Some traditional implementations attempt to reduce inter-cell CLI in TDD networks caused by flexible and dynamic timeslot format configurations. Two CLI measurement reports that manage and coordinate scheduling between neighboring gNBs include: Sounding Reference Signal (SRS) Reference Signal Received Power (RSRP) and CLI Received Signal Strength Indicator (RSSI). In SRS-RSRP, the linear average of the power contribution of the SRS transmitted by the UE is measured by the UE in neighboring cells. This is measured on the configured resource elements within the measurement frequency bandwidth considered, in the time resources in the configured measurement occasions. In CLI-RSSI, the linear average of the observed total received power is measured only at certain OFDM symbols of the measurement time resources, in the measurement bandwidth, on the configured resource units for measurement by the UE.

[0062] Both SRS-RSRP and CLI-RSSI are RRC measurements and are performed by the UE for mitigating UE-to-UE inter-cell CLI. For SRS-RSRP, an interferer UE (i.e., a UE whose UL transmission causes interference at another UE in a neighboring cell) will transmit an SRS in the uplink, and a victim UE in a neighboring cell (i.e., a UE experiencing interference caused by UL transmissions from UEs in a neighboring cell) will be configured with a measurement configuration including the SRS parameters of the interferer UE in order to allow measurement of interference from the interferer UE. Figure 5 An example is shown in FIG. 5 , where, at a particular timeslot, the 11th OS (OFDM symbol) of gNB1 511 and gNB2 512 causes an inter-cell CLI. Here, gNB1 511 has configured UE1 521 (interferer UE) to transmit SRS 540, and gNB2 512 has configured UE2 522 (victim UE) to measure the SRS 540. The SRS configuration parameters of UE1 521, such as the RS sequence used, frequency resources, frequency transmission comb structure, and time resources, are provided to UE2 522 so that UE2 522 can measure SRS 540. Typically, a UE can be configured to monitor 32 different SRS at a maximum rate of 8 SRS per timeslot.

[0063] For CLI-RSSI measurements, the UE measures the total received power (i.e., signal and interference) after a configured period, the start and end OFDM symbols of a time slot, and a set of frequency resource blocks (RBs). Since SRS-RSRP measures the transmissions made by a specific UE, the network can target specific interferer UEs to reduce their transmission power and, in some cases, not schedule interferer UEs at the same time as victim UEs reporting high SRS-RSRP measurements. In contrast, CLI-RSSI cannot be used to identify the transmissions of a specific interferer UE, but CLI-RSSI does provide an overall estimate of the inter-cell CLI experienced by the victim UE.

[0064] Intra-cell cross-link interference (CLI) and sub-band full-duplex (SBFD)

[0065] In addition to inter-cell CLI and long-range interference, FD-TDD also suffers from intra-cell CLI at the gNB and UE. Figure 6 An example is shown in FIG. 6 where a gNB 610 is FD-TDD capable and is simultaneously receiving an UL transmission 631 from UE1 621 and transmitting a DL transmission 642 to UE2 622. At the gNB 610, the intra-cell CLI is caused by the DL transmission 642 at the gNB's transmitter self-interference 641, which has its own receiver attempting to decode the UL signal 631. At UE2 622, the intra-cell CLI 632 is caused by, for example, an interferer UE (UE1 621) transmitting the UL 631 while a victim UE (UE2 622) is receiving the DL signal 642.

[0066] Due to self-interference, intra-cell CLI at the gNB can be significant, as DL transmissions can in some cases be more than 100 dB stronger than UL reception. Therefore, complex RF hardware and interference cancellation are required to isolate this self-interference. To reduce self-interference at the gNB, one possibility considered in [3], [4] is sub-band full duplex (SBFD). In SBFD, the frequency resources of the TDD system bandwidth or bandwidth part (BWP) (i.e., at the UE / gNB) are divided into two or more non-overlapping subbands, where each subband can be either DL or UL [5]. Figure 7 An example is shown in FIG, where simultaneous DL and UL transmissions occur in different non-overlapping subbands 701 to 704, i.e., in different groups of frequency resource blocks (RBs): subband #1 701, subband #2 702, subband #3 703, and subband #4 704, such that subband #1 701 and subband #3 703 are used for DL ​​transmission, while subband #2 702 and subband #4 704 are used for UL transmission.

[0067] Although Figure 7The system bandwidth is shown as being divided into four subbands, but essentially any number of subbands may be used. For example, the system bandwidth may be divided into three subbands, which may include two downlink subbands 701, 703 and one uplink subband 702 (although other subband arrangements are contemplated). To reduce leakage from one subband 701 to 704 to another, a guard subband 710 may be configured between the UL and DL subbands 701 to 704. The guard subband 710 is configured between UL subband #4 704 and DL subband #3 703, between DL subband #3 703 and UL subband #2 702, and between UL subband #2 702 and DL subband #1 701. Figure 7 The arrangement of sub-bands 701 to 704 shown in FIG. 1 is only one possible arrangement of sub-bands, other arrangements are possible, and guard bands may be used in essentially any arrangement of sub-bands.

[0068] Inter-subband interference

[0069] In addition to inter-cell cross-link interference, SBFD also suffers from inter-(and intra-)sub-band interference caused by transmission leakage and receiver selectivity. Although transmissions are usually scheduled within a specific frequency channel (or sub-band), i.e., a specific set of RBs, the transmission power will still leak into other channels. This occurs because the channel filter is not perfect, and therefore the roll-off of the filter will cause power to leak into channels adjacent to the intended specific frequency channel. Although the following discussion uses the term channel, the term sub-band can be used instead, such as Figure 7 The subbands shown in .

[0070] Figure 8 An example of a transmission that produces adjacent channel leakage is shown in FIG. Here, the desired transmit (Tx) power is the transmit power in the selected frequency band (i.e., the assigned channel 810). Due to the roll-off of the transmit filter and nonlinearities in the components of the transmitter, some of the transmit power leaks into adjacent channels (including adjacent channel 820), such as Figure 8 The ratio of the power in the allocated frequency channel 810 to the power in the adjacent channel 820 is the adjacent channel leakage ratio (ACLR). The leakage power 850 will cause interference at the receiver that is receiving the signal in the adjacent channel 820.

[0071] Similarly, the receiver's filter is not perfect and will receive unwanted power from adjacent channels due to its own filter roll-off. Fig. 9An example of filter roll-off at a receiver is shown. Here, the receiver is configured to receive transmissions in the assigned channel 910. However, the imperfect characteristics of the receiver filter mean that some transmission power 950 may be received in the adjacent channel 920. Therefore, if a signal 930 is transmitted on the adjacent channel 920, the receiver will, to some extent, inadvertently receive the adjacent signal 930 in the adjacent channel 920. The ratio of the received power in the assigned frequency channel 910 to the received power 950 in the adjacent channel 920 is the adjacent channel selectivity (ACS).

[0072] The combination of the ACL from the transmitter and the ACS at the receiver will result in adjacent channel interference (ACI) at the receiver, also known as inter-sub-band interference. Fig.10 An example is shown where an interferer transmits a signal 1010 in an adjacent channel at a lower frequency than a victim receive channel 1020. The interference 1050 caused by the interferer's transmission includes the ACL 1051 of the interferer's transmit filter and the ACS 1052 of the victim's receive filter. In other words, the receiver will experience Fig.10 Interference 1050 in the ACI frequency range is shown.

[0073] Therefore, due to adjacent channel interference (ACI), cross link interference (CLI) still occurs, although Figure 7 As shown in the example of , different subbands 701 to 704 are used for DL ​​and UL transmissions in the FD-TDD cell. The proposed SRS-RSRP and CLI-RSSI measurements specified for inter-cell CLI assume that the interferer and the victim transmit and receive in the same frequency channel. That is, the measurements of SRS-RSRP and CLI-RSSI at the victim UE are performed in the same frequency channel as the interferer's frequency channel. Therefore, these methods do not consider the use of ACI and subbands 701 to 704 to provide information to the scheduler to mitigate intra-cell CLI.

[0074] Intra-subband interference

[0075] Intra-subband interference can occur when the subband configurations between gNBs are not aligned in the frequency domain. Here, CLI can occur in the overlapping frequencies of inter-cell subbands. Fig.11An example is shown in FIG, where the 1111 system bandwidth of gNB1 is divided into UL subband UL-SB#1 1152 occupying f0 to f2 and DL subband DL-SB#1 1151 occupying f2 to f3, while the 1112 system bandwidth of gNB2 is divided into UL subband UL-SB#2 1154 occupying f0 to f1 and DL subband DL-SB#2 1153 occupying f1 to f3. The misaligned subband configuration 1150 causes UL-SB#1 1152 to overlap with DL-SB#2 1153, thereby inducing intra-subband CLI within the overlapping frequencies f1 to f2. In this example, since DL transmission 1132 of gNB2 1112 within f1 to f2 in DL-SB#2 1153 interferes with UL reception 1131 of gNB1 1111 from UE1 1121 within f1 to f2 in UL-SB#1 1152, intra-subband CLI 1141 occurs at gNB1 1111. In addition, since UL transmission 1131 of UE11121 within f1 to f2 in UL-SB#1 1152 interferes with DL reception 1132 of UE2 1122 within f1 to f2 in DL-SB#2 1153, intra-subband CLI 1142 occurs at UE2 1122.

[0076] Frequency Domain Resource Allocation (FDRA)

[0077] PDSCH frequency resources are allocated in the DL grant or activation DCI for semi-persistent resources (SPS). Similarly, PUSCH frequency resources are allocated in the UL grant or activation DCI for configured grant (CG)-PUSCH. Frequency resource allocation is indicated in the frequency domain resource allocation (FDRA) field of the DCI for PDSCH and PUSCH. There are three types of FDRA, of which type 0 and type 1 are used for PDSCH and PUSCH, and type 2 is used only for PUSCH in Rel-17 (i.e., for NR unlicensed (NR-U)).

[0078] In Type 0 FDRA, the resource blocks (RBs) in the bandwidth part (BWP) are divided into N RBG Resource Block Group (RBG), where the size of the RBG is configurable and depends on the BWP N in the RB BWP This is shown in the following Table I reproduced from [6], where, as included in Table 5.1.2.2.1-1. FDRA consists of a size of N RBG A bitmap of bits where the gNB has the flexibility to indicate which RBG PDSCH or PUSCH occupies, i.e., PDSCH and PUSCH frequency resources can be non-contiguous.

[0079] Table I: RGB sizes (reproduced from [6])

[0080] Bandwidth portion size Configuration 1 Configuration 2 1–36 2 4 37–72 4 8 73–144 8 16 145–275 16 16

[0081] In Type 1 FDRA, PDSCH or PUSCH occupies a contiguous set of RBs. The FDRA indicates the starting RB of PDSCH or PUSCH and the length of the RBs occupied by PDSCH or PUSCH. As in Type 0 FDRA, the gNB has no flexibility in allocating non-contiguous RBs for PDSCH or PUSCH, but has a finer granularity of PDSCH / PUSCH size (i.e., granularity of one or more RBs instead of RBGs) compared to Type 0 FDRA. The number of bits used for Type 1 FDRA is Thus, while a Type 1 FDRA may generally be considered more efficient in the amount of resources allocated (due to lower granularity), it is less flexible than a Type 0 FDRA because the allocations cannot be non-contiguous.

[0082] The UE may be configured to dynamically switch between Type 0 and Type 1, where the most significant bit (MSB) (1 bit) of the FDRA is used to indicate whether Type 0 or Type 1 FDRA is being used. Therefore, the number of bits used to dynamically switch FDRA is

[0083] In unlicensed operation, the frequency resources of the BWP are divided into RB sets, where each RB set has a bandwidth of 20 MHz. The gNB can allocate one or more RB sets to the UE, for example, for PUSCH transmission. The provisions for unlicensed operation require that the RB set be fully occupied so that its energy can be detected by another device for LBT purposes.

[0084] Type 2 FDRA is introduced for unlicensed operation to meet the unlicensed operation requirements, where in Type 2 FDRA, RBs are allocated in an interleaved manner. M is defined for 15kHz and 30kHz subcarrier spacing (SCS), respectively. interlace = 10 or 5 interleaving patterns, where in each interleaving pattern, the allocated RBs start with a different RB offset, followed by M interlace RB steps. Fig.12 An example of 30kHz SCS interleaving allocation is shown in FIG. 1 , where in a 20MHz RB set, M interlace = 5 patterns, numbered {0, 1, 2, 3, 4}. The gNB may allocate PUSCH to occupy one or more interleaving patterns. Fig.12In the example, interleaving patterns numbered 1 and 3 are assigned to PUSCH. Once an interleaving pattern is assigned to an RB set, the gNB can further allocate multiple RB sets in a BWP, where the RB sets are allocated by defining the starting RB set and the number of consecutive RB sets being allocated. Fig.12 In the example in , the gNB indicates RB set 1 and 3 RB sets, thereby allocating PUSCH to occupy RB set 1, RB set 2, and RB set 3, where interleaving patterns 1 and 3 are used in each RB set.

[0085] The bit size of the FDRA field of Type 2 is Among them, N RB_Set is the number of RB sets in the BWP, and X interlace =6 and 5 (for 15kHz and 30kHz SCS respectively), indicating the assigned interleaving pattern.

[0086] like Fig.13 and Fig.14 As shown respectively, the two frequency configurations considered for the subband are 2DL+1UL and 1DL+1UL. However, those skilled in the art will appreciate that Fig.13 and Fig.14 Such configurations illustrated in are just two examples, and any possible configuration may be used, with one or more DL subbands and one or more UL subbands arranged in any conceivable pattern.

[0087] The 2DL+1UL configuration consists of two DL subbands 1301 and 1303, with the UL subband 1302 in the middle, i.e. Fig.13 As shown in , between two DL subbands. Fig.14 As shown, the 1DL+1UL configuration consists of one DL subband 1401 and one UL subband 1402. For the 1DL+1UL subband configuration, the UL subband 1402 may start at the lower end of the frequency bandwidth (e.g., at f0) and end at the middle of the bandwidth (i.e., f1). Fig.14 1401), or after the DL subband 1401, the UL subband 1402 may start in the middle of the bandwidth (i.e., at f2) and end at the higher edge of the frequency bandwidth (at f3) (as shown in the top configuration of FIG. 1402 ). Fig.14 ).

[0088] For Type 0 and Type 1 FDRA, the bit size of the FDRA field is proportional to the number of RBs N in the BWP. BWP However, in SBFD operation, only a portion of the BWP is used for PDSCH or PUSCH, which means that some FDRA bits are redundant. Fig.13For the 2DL+1UL subband configuration shown (or indeed any SBFD configuration with more than one DL and / or UL subband with non-contiguous positioning), if two DL subbands need to be allocated to the UE, a discontinuous PDSCH allocation such as type 0 is required. This is because a type 1 allocation will be limited to one DL subband, which is because a type 1 allocation cannot be discontinuous. It should be noted here that for configuration 1 of type 0 that provides a finer RBG granularity (see Table I above), the FDRA of type 0 uses more bits than type 1, which makes it invalid. If a type 2 FDRA is considered, the same problem of using a large number of bits will be true, thus making it invalid as well. In addition, type 0 cannot be used for fallback DCI, i.e., DCI formats 0_0 and 1_0 for UL authorization and DL authorization, respectively, which are DCIs with a relatively small number of bits (which can be used for purposes such as initial access), and therefore a type 0 FDRA may be too coarse. Therefore, a new FDRA method suitable for SBFD operation is needed.

[0089] Therefore, embodiments of the present technology attempt to provide a solution to this problem and propose a new FDRA method that is effective and suitable for SBFD operations.

[0090] Mirrored FDRA for SBFD operations

[0091] Fig.15 A partially schematic partial message flow diagram representation of a wireless communication system including a communication device 1501 and an infrastructure device 1502 according to at least some embodiments of the present technology is shown. The communication device 1501 is configured to transmit signals to and / or receive signals from a wireless communication network, for example, to and from the infrastructure device 1502. Specifically, the communication device 1501 may be configured to transmit data to and / or receive data from the wireless communication network (for example, to / from the infrastructure device 1502) via a wireless radio interface provided by the wireless communication network (for example, a Uu interface between the communication device 1501 and a radio access network (RAN), the RAN including the infrastructure device 1502). The communication device 1501 and the infrastructure device 1502 each include a transceiver (or transceiver circuit) 1501.1, 1502.1 and a controller (or controller circuit) 1501.2, 1502.2. Each controller 1501.2, 1502.2 may be, for example, a microprocessor, a CPU, or a dedicated chipset.

[0092] like Fig.15As shown in the example of , the transceiver circuit 1501.1 and the controller circuit 1501.2 of the communication device 1501 are configured in combination to receive 1510 a control signal from the wireless communication network (e.g., from the infrastructure equipment 1502), the control signal indicating a resource allocation, the resource allocation being used for the communication device 1501 to transmit an uplink transmission to the wireless communication network (e.g., to the infrastructure equipment 1502) or receive a downlink transmission from the wireless communication network (e.g., from the infrastructure equipment 1502) within a set of consecutive resource units (which may define a bandwidth part (BWP)) of a wireless radio interface (e.g., a Uu interface between the communication device 1501 and the infrastructure equipment 1502), wherein the set of consecutive resource units includes one or more uplink frequency sets and one or more downlink frequency sets, each uplink frequency set includes a plurality of uplink resource units, each downlink frequency set includes a plurality of downlink resource units, and wherein the resource allocation indicates the resource allocation for the uplink 1502, receiving 1520 a duplication indication from the wireless communication network (e.g., from the infrastructure device 1502), the duplication indication being used to indicate that resource allocations for uplink transmissions in the first uplink frequency set are repeated in one or more other uplink frequency sets and / or in the first uplink frequency set, or that resource allocations for downlink transmissions in the first downlink frequency set are repeated in one or more other downlink frequency sets and / or in the first downlink frequency set; and, transmitting 1530 an uplink transmission to the wireless communication network (e.g., to the infrastructure device 1502) or receiving a downlink transmission from the wireless communication network (e.g., from the infrastructure device 1502) based on the resource allocations and the duplication indications.

[0093] Here, those skilled in the art will understand that the first uplink frequency set and the first downlink frequency set mentioned in the above paragraphs and elsewhere in this document are not necessarily the first sets in frequency (although this may be the case in some implementations), but refer to any one of the uplink frequency sets and any one of the downlink frequency sets.

[0094] In essence, embodiments of the present technology propose to introduce a new type of FDRA (which may be referred to as a mirrored FDRA), in which the allocated RBs of the PDSCH or PUSCH / PUCCH in a frequency set are also allocated in another one or more frequency sets. Here, in some arrangements of embodiments of the present technology, the frequency set may be a DL or UL subband, although those skilled in the art will recognize that embodiments of the present technology may be applied similarly to arrangements where the frequency set is not a DL or UL subband. Although reference is made to frequency sets and subbands in the present disclosure, those skilled in the art will understand that these terms are interchangeable, and in fact even in the case where a DL or UL frequency set is referred to as a DL or UL subband, such description is intended to extend to arrangements where the described frequency set is not a DL or UL subband.

[0095] In some arrangements of embodiments of the present technology, whether to use the mirrored FDRA scheme may be semi-statically configured. In other words, a duplication indication may be received within a radio resource control RRC signaling.

[0096] In some arrangements of the embodiments of the present technology, it is possible to dynamically indicate in the DCI whether to use the mirrored FDRA. For example, a 1-bit field may be defined in a DL authorization or a UL authorization or in an activation DCI for SPS / CG-PUSCH to switch the mirrored FDRA on or off according to the arrangement of the embodiments of the present technology. In other words, a copy indication may be received in the downlink control information DCI, where the DCI may be a control signal (i.e., a signal carrying the UL / DL authorization). In addition, the control signal here may be an activation DCI indicating that at least one instance of a group of unauthorized resources is activated or deactivated, where the group of unauthorized resources is a resource allocation for a communication device to transmit an uplink transmission to a wireless communication network or receive a downlink transmission from a wireless communication network in an unauthorized manner.

[0097] In some arrangements of embodiments of the present technology, a DCI (or activation DCI) carrying a DL grant or a UL grant using an FDRA based on SBFD may use a separate radio network temporary identifier (RNTI) that is different from a DCI (or activation DCI) carrying a DL grant or a UL grant using an FDRA not based on SBFD (i.e., conventional TDD). In other words, the control signal may be associated with a first identifier that implicitly indicates a duplication indication and is different from at least a second identifier that may be associated with other DCI that does not include a duplication indication.

[0098] In some arrangements of embodiments of the present technology, the search space and / or CORESET for transmitting DCI (or activating DCI) carrying DL grant or UL grant using FDRA based on SBFD may be different from the search space and / or CORESET for transmitting DCI (or activating DCI) carrying DL grant or UL grant not based on FDRA based on SBFD (i.e., conventional TDD). In other words, the control signal may be received by the communication device within a specific set of resources (i.e., search space or CORESET) of the wireless radio interface, wherein the reception of the control signal within the specific set of resources implicitly indicates a duplication indication.

[0099] In some arrangements of embodiments of the present technology, in the case of applying mirrored FDRA, the bandwidth of (at least) two frequency sets may always be configured to be the same. For example, the number of RBs in the two DL subbands may be the same. In other words, the first uplink frequency set and at least two of the one or more other uplink frequency sets may have the same bandwidth as each other, and / or the first downlink frequency set and at least two of the one or more other downlink frequency sets may have the same bandwidth as each other.

[0100] In some arrangements of embodiments of the present technology, a common modulation and coding scheme (MCS), a new data indicator (NDI), and a redundancy version indicator (RI) in the DCI may be applied to each PDSCH or PUSCH (or PUCCH) allocated in each frequency set. In other words, the DCI carries a single MCS, NDI, and RI value for each PDSCH, PUSCH, or PUCCH. That is, the control signal may define a single value for each of the one or more communication parameters for all first uplink frequency sets and one or more other uplink frequency sets, and / or the control signal may define a single value for each of the one or more communication parameters for all first downlink frequency sets and one or more other downlink frequency sets.

[0101] In some other arrangements of embodiments of the present technology, each MCS, NDI and RI in the DCI may be applied separately to each PDSCH or PUSCH allocated in each frequency set. In other words, the DCI carries multiple MCSs, NDIs and RIs corresponding to each frequency set, where each MCS, NDI or RI value may be applied to one or more frequency sets individually or on a group basis, but not shared across all frequency sets. That is, the control signal may define different values ​​for each of the one or more communication parameters for each of the first uplink frequency set and one or more other uplink frequency sets, and / or the control signal may define different values ​​for each of the one or more communication parameters for each of the first downlink frequency set and one or more other downlink frequency sets.

[0102] In some arrangements of embodiments of the present technology, DL and UL subbands (or frequency sets) may be semi-statically configured or dynamically allocated by the gNB. In other words, one or more uplink frequency sets and one or more downlink frequency sets may be configured within RRC signaling received by the communication device from the wireless communication network, and / or one or more uplink frequency sets and one or more downlink frequency sets may be dynamically allocated by the DCI received by the communication device from the wireless communication network. For dynamic allocation, the frequency set configuration (i.e., location) may or may not be transparent to the UE. That is, if the frequency set is transparent to the UE, the DCI scheduling will implicitly configure the frequency set at the UE without the UE knowing the configuration of these frequency sets. Instead, the UE will only know the allocated resources within these frequency sets. Those skilled in the art will understand that the mirrored FDRA method as defined by the embodiments of the present disclosure can be applied to semi-statically configured and dynamically allocated subbands (or frequency sets).

[0103] In some arrangements of embodiments of the present technology, the mirrored FDRA may be Mirror and repeat N Mirror PDSCH / PUSCH / PUCCH RBs are repeated N times. It should be noted here that PDSCH RBs are repeated N times in the frequency domain. Mirror The gNB indicates the RB allocation for one frequency set, and then the RB allocation is repeated N times (i.e., as may be defined by a set of contiguous resource units, which may themselves define a BWP) rather than the PDSCH / PUSCH / PUCCH itself. That is, only a single PDSCH / PUSCH / PUCCH is allocated on these repeated RBs. The gNB indicates the RB allocation for one frequency set, and then the RB allocation is repeated N times. Mirror times and has O Mirror In other words, resource allocation in the first uplink frequency set may be based on the first parameter (ie, N Mirror ) and the second parameter (i.e., O Mirror ) is repeated in one or more other uplink frequency sets, the first parameter defines the number of repetitions of the resource allocation and the second parameter defines the offset between each repetition of the resource allocation, or according to the first parameter (i.e., N Mirror ) and the second parameter (i.e., O Mirror ), the resource allocation in the first downlink frequency set may be repeated in one or more other downlink frequency sets.

[0104] Fig.16 An example is shown where PDSCH may be scheduled to occupy non-contiguous RBs on three frequency sets 1602, 1603, 1604. The gNB indicates FDRA 1601 occupying f1 to f2, where the allocation is in units ofMirror 1605 offset repeat N Mirror = 3 times, resulting in PDSCH RB occupying frequencies f1-f2, f5-f6 and f9-f 10 It should also be understood that although Fig.16 The example in is for DL ​​transmission, but Fig.16 The exemplary arrangement shown is also applicable to UL transmission in a similar and corresponding manner. According to this arrangement, the gNB is able to use a smaller FDRA bit size because it only needs to indicate the FDRA within the frequency set rather than the entire bandwidth portion. The gNB can also use Type 1 FDRA to achieve non-contiguous allocation on the BWP, allowing DCI formats 0_0 and 0_1 to indicate non-contiguous RBs while benefiting from the granularity advantage of Type 1 FDRA.

[0105] As with the frequency set itself, the offset O Mirror and RB repetition factor N Mirror It may be semi-statically configured, dynamically indicated in the DCI and / or fixed in the specification. In other words, the first parameter and / or the second parameter may be configured within the RRC signaling received by the communication device from the wireless communication network. Alternatively or additionally, the first parameter and / or the second parameter may be dynamically indicated by the DCI received by the communication device from the wireless communication network. Alternatively or additionally, the first parameter and / or the second parameter may be predefined and known to the communication device (and indeed to the wireless communication network / infrastructure equipment). Some parameters may be semi-statically configured and some dynamically indicated; for example, Mirror can be semi-statically configured, and N Mirror Dynamically indicated in DCI.

[0106] It should be noted that in some arrangements of embodiments of the present technology, by Mirror The RB repetition method can also be applied to a single subband. In other words, the resource allocation in the first uplink frequency set can be based on the first parameter (ie, N Mirror ) and the second parameter (i.e., O Mirror ) is repeated in the first uplink frequency set, the first parameter defines the number of repetitions of the resource allocation and the second parameter defines the offset between each repetition of the resource allocation, or the resource allocation in the first downlink frequency set may be based on the first parameter (i.e., N Mirror ) and the second parameter (i.e., O Mirror ) is repeated in the first downlink frequency set.

[0107] exist Fig.17 An example is shown in FIG. 1 , where the subband configuration consists of 1 DL+1 UL, and where Mirror1705 is smaller than the DL sub-bandwidth. The DL grant only needs to indicate that PDSCH 1701 occupies f1 to f2 (ie, within DL sub-band 1702), and for PDSCH, RB repetition is then allocated f3 to f4, i.e., Mirror 1705 offset. In this example, assume that N Mirror is 2. It should be appreciated that this arrangement is also applicable to the case where no subbands are configured, in which case RB repetition will occur within the BWP itself.

[0108] In addition, in some other arrangements of embodiments of the present technology, those skilled in the art will appreciate that the RB repetition method may be applicable within a single subband and on one or more other subbands. Fig.13 In the DL-UL-DL arrangement shown in FIG, PDSCH may be in a single DL subband as described above. Fig.17 The described manner is repeated, but may also be repeated in other DL subbands (and here, in other subbands, the PDSCH may be repeated, for example, once or twice). In some implementations, this may be accomplished by two different O Mirror parameters (i.e., one smaller than the DL sub-bandwidth and the other larger than the DL sub-bandwidth).

[0109] In some arrangements of embodiments of the present technology, the offset O Mirror It may be a frequency separation between two DL subbands or between two UL subbands. In other words, the offset defined by the second parameter may be the same as the frequency separation between the first downlink frequency set and at least two of one or more other downlink frequency sets, or between the first uplink frequency set and at least two of one or more other uplink frequency sets. That is, the second parameter defines that the resource allocation in the first uplink frequency set may be repeated in at least one uplink resource unit of one or more other uplink frequency sets corresponding to at least one uplink resource unit of the first uplink frequency set indicated by the resource allocation, or the resource allocation in the first downlink frequency set may be repeated in at least one downlink resource unit of one or more other downlink frequency sets corresponding to at least one downlink resource unit in the first downlink frequency set indicated by the resource allocation.

[0110] In some arrangements of embodiments of the present technology, the RB repetition factor N Mirror may be equal to the number of DL subbands or the number of UL subbands in the BWP. In other words, the number of repetitions of the resource allocation defined by the first parameter may be the same as the total number of the first downlink frequency set and one or more other downlink frequency sets, or the same as the total number of the first uplink frequency set and one or more other uplink frequency sets.

[0111] In some arrangements of embodiments of the present technology, the mirror FDRA may be a reflection of the RB allocation in the first frequency set to the second frequency set on a reflection line. In other words, the resource allocation in the first uplink frequency set may be reflected into one or more other uplink frequency sets according to a reflection parameter that defines a reflection line within the group of consecutive resource units on which the resource allocation is reflected, or the resource allocation in the first downlink frequency set may be reflected into one or more other downlink frequency sets according to the reflection parameter.

[0112] Fig.18 An example is shown in FIG. 1 , where the gNB schedules PDSCH to occupy non-contiguous RBs. Here, the gNB instructs FDRA 1801 to allocate RBs in the first frequency set 1802 to occupy f1-f2, and according to such an arrangement, a reflection line 1804 is defined, at Fig.18 In the example of , the reflected line is in the middle of the first frequency set 1802 and the second frequency set 1803. The RBs allocated in the first frequency set 1802 are therefore reflected on the second frequency set 1803, resulting in RBs occupying f5-f6.

[0113] One way to implement such an arrangement is to simply have the reflection parameter explicitly define the reflection line 1804 (i.e., the frequency value or RB of the reflection resource allocation). In other words, the reflection parameter may explicitly define the reflection line. Alternatively, another way to implement such an arrangement is to calculate the offset O between the edge of the first frequency set 1802 at f0 and the allocated RB (e.g., f1). Reflect 1805, then applying an offset O from the opposite edge of the second frequency set 1803 at f7 Reflect 1806 to allocate the reflected RB (e.g., at f6), such as Fig.18 As shown in the example in . In other words, the reflection parameter may define, for each uplink resource unit of the first uplink frequency set, an offset between the uplink resource unit and the beginning of the first uplink frequency set, or, for each downlink resource unit of the first downlink frequency set, an offset between the downlink resource unit and the beginning of the first downlink frequency set. Any of such techniques (or indeed techniques according to any other contemplated implementations) is performed for each allocated RB in the first frequency set, such that the reflected RB is also allocated in the second frequency set. As described above, those skilled in the art will appreciate that other implementations for determining the reflected RBs may of course be used.

[0114] Reflection parameters - such as offset O Reflect or reflection line - (and similarly offset O Mirror , RB repetition factor N Mirror, and the frequency set itself as described above) can be semi-statically configured, dynamically indicated in the DCI and / or fixed in the specification. In other words, the reflection parameter can be configured within the RRC signaling received by the communication device from the wireless communication network. Alternatively or additionally, the reflection parameter can be dynamically indicated by the DCI received by the communication device from the wireless communication network. Alternatively or additionally, the reflection parameter can be pre-defined and known to the communication device (and indeed to the wireless communication network / infrastructure equipment).

[0115] It should be noted that the RB reflection method can also be adapted to within a single subband or within a BWP (with or without any subband level configuration) by placing the reflection line within the subband (or within the BWP). In other words, the resource allocation in the first uplink frequency set can be reflected into the first uplink frequency set according to the reflection parameter, which defines the reflection line within the group of consecutive resource units on which the resource allocation is reflected, or the resource allocation in the first downlink frequency set can be reflected into the first downlink frequency set according to the reflection parameter.

[0116] Fig.19 An example is shown in FIG. 1 , where the BWP is configured with a 1DL+1UL subband configuration and the reflection line 1904 is placed in the middle of the DL subband 1902. The DL grant uses a type 1 FDRA 1901 to allocate RBs occupying f1 to f2, and by using the RB reflection method, RBs in f3 to f4 are also allocated, thereby providing non-contiguous RBs for the scheduled PDSCH.

[0117] In addition, in some other arrangements of embodiments of the present technology, those skilled in the art will appreciate that the RB reflection method may be applicable both within a single sub-band and on one or more other sub-bands. Fig.13 In the DL-UL-DL arrangement shown in FIG, the PDSCH may be in a single DL subband as described above with respect to Fig.19 The PDSCH may be reflected in the manner described above, but may also be reflected into other DL subbands (and here, the PDSCH may be included in the other subbands, for example, once or twice). In some implementations, this may be done by two different Reflect This may be achieved by using multiple reflection lines (eg, one of which is placed in a first DL sub-band for reflection in the DL sub-band, and another of which is placed in, for example, a UL sub-band for reflection into another DL sub-band).

[0118] In some arrangements of embodiments of the present technology, a mapping of RBs of a first frequency set to RBs in one or more other frequency sets may be defined. In other words, the communication device (and in fact, the corresponding wireless communication network / infrastructure equipment) may be configured to: determine a mapping between each of the uplink resource units of the first uplink frequency set and the corresponding uplink resource unit of at least one of the one or more other uplink frequency sets, and / or between each of the downlink resource units of the first downlink frequency set and the corresponding downlink resource unit of at least one of the one or more other downlink frequency sets, and determine that the resource allocation in the first uplink frequency set is repeated in one or more other uplink frequency sets according to the determined mapping, or determine that the resource allocation in the first downlink frequency set is repeated in one or more other downlink frequency sets according to the determined mapping. Here, the mapping may be defined by a lookup table or based on an equation, the RBs of the first frequency set may be used as input to the equation, and from the equation, the corresponding RBs of the second frequency set may be determined as output.

[0119] An exemplary mapping using a lookup table is shown in Table II below, where in this example, the frequency set consists of 10 RBs, labeled first, second, third, etc. and in Fig. 20 The gNB may indicate in the FDRA field of the UL grant (or similarly, the DL grant or activation DCI, etc.) that the fourth, fifth, sixth, and seventh RBs in the first frequency set 2001 are allocated, which also indirectly indicates that the ninth, tenth, first and second RBs in the second frequency set 2002 are allocated through the mapping shown in Table II, as shown in Table II. Fig. 20 As shown. Those skilled in the art will appreciate that the mapping shown in Table II is only one example of RB mapping, and other mappings are certainly possible. It should also be understood that relative to Fig. 20 This arrangement of the embodiment of the present technology is also applicable to DL transmissions other than UL transmissions (PUSCH and PUCCH). This mapping can be extended to other frequency sets, i.e., mapping between the first frequency set 2001, the second frequency set 2002, and the third frequency set, and mapping between later frequency sets in the BWP or between the first frequency set 2001 and only some of the other frequency sets in the BWP.

[0122]

[0123] In some arrangements of embodiments of the present technology, the mapping between RBs of a frequency set and RBs in one or more other frequency sets may be configured semi-statically. In other words, the mapping may be configured within RRC signaling received by the communication device from the wireless communication network.

[0124] In some arrangements of embodiments of the present technology, the mapping between RBs of a frequency set and RBs in one or more other frequency sets may be fixed in the specification. In other words, the mapping is predefined and known to the communication device (and in fact to the wireless communication network / infrastructure equipment).
