Description

Technical Field

[0001] The present disclosure relates to communication devices, infrastructure devices, and methods for operating communication devices and infrastructure devices in a wireless communication network.

Background Art

[0002] This application claims priority under the Paris Convention based on European Patent Application No. EP20167632.7, the content of which is incorporated herein by reference.

[0003] The description of "Background Art" provided herein is for the purpose of generally presenting the context of the present disclosure. The research of the inventors is not admitted, explicitly or implicitly, as prior art to the present invention to the extent that it is described in this background art section and would not otherwise be considered prior art at the time of filing.

[0004] Third and fourth generation mobile communication systems, such as those based on the 3GPP (registered trademark) defined UMTS and Long Term Evolution (LTE) architectures, can support services more sophisticated than the simple voice and messaging services provided by previous generation mobile communication systems. For example, using the improved radio interface and extended data rates provided by the LTE system, users can enjoy high data rate applications such as mobile video streaming and mobile video conferencing that would previously have been available only via a fixed-line data connection. Therefore, the need to deploy such networks is strong, and the coverage areas of these networks, i.e., the geographical locations where access to the network is possible, are expected to increase more rapidly.

[0005] Future wireless communication networks are expected to support communication with a wider range of devices on a daily and efficient basis, related to a wider range of data traffic profiles and types than existing systems are optimized to support. For example, future wireless communication networks are expected to efficiently support communication with devices including reduced complexity devices, machine type communication (MTC) devices, high resolution video displays, virtual reality headsets, etc. Some of these different types of devices may be deployed in a very large number of low complexity devices, for example, to support the "Internet of Things", and are typically associated with the transmission of relatively small amounts of data with relatively high latency tolerance.

[0006] Therefore, it is expected that future wireless communication networks, such as those sometimes referred to as 5G or new radio (NR) systems / new radio access technology (RAT) systems (Non-Patent Document 1), as well as future iterations / releases of existing systems, will efficiently support connectivity for a wide range of devices associated with different applications and different characteristic data traffic profiles.

[0007] Systems incorporating NR technology are expected to support different services (or different types of services) that can be characterized by different requirements regarding latency, data rate, and / or reliability. For example, the objective of enhanced mobile broadband (eMBB) services is to provide 10% reliability with a user plane latency of 4 ms, and the objective of ultra reliable and low latency communications (URLLC) services is 1 - 10 for a single transmission of a 32-byte packet with a user plane latency of 1 ms -5To provide reliability of (99.999%) or more (Non-Patent Document 3). Further, in order to support services with new requirements of high availability, high reliability, low latency, and in some cases high-precision positioning, the system may be expected to support further enhancements related to the Industrial Internet of Things (IIoT).

[0008] Therefore, the data for transmission can be associated with different services and / or different quality of service requirements. Therefore, it is necessary to provide technologies and devices that enable data with different requirements to be efficiently transmitted within a wireless communication network.

[0018] (Long Term Evolution - Advanced Wireless Access Technology (4G)) FIG. 1 is a schematic diagram showing some of the basic functions of a mobile telecommunications network / system 100 that generally operates according to LTE principles but can also support other radio access technologies and can be adapted to implement the various embodiments of the present disclosure as described herein. Some aspects of the various elements of FIG. 1 and their respective modes of operation are well known and are defined in the relevant standards administered by the 3GPP (RTM) body and are also described in many books on the subject, such as Non-Patent Document 2. It should be understood that the operating modes of the telecommunications network discussed herein that are not specifically described (e.g., with respect to specific communication protocols and physical channels for communicating between different elements) may be implemented, for example, in accordance with any known techniques related to the relevant standards as well as any known proposed modifications and additions to the relevant standards.

[0019] Network 100 includes a plurality of base stations 101 connected to the core network portion 2. Each base station 100 provides a coverage area 103 (e.g., a cell) in which data can be communicated with a communication device 104. Data is transmitted from the base station 101 to the communication devices 104 within their respective coverage areas 103 via the wireless downlink. Data is transmitted from the communication devices 104 to the base station 101 via the wireless uplink. The core network portion 102 routes data to and from the communication devices 104 via the respective base stations 101 and provides functions such as authentication, mobility management, and charging. Communication devices may also be referred to as mobile stations, user equipment (UE), user terminals, mobile radios, terminal devices, etc. A base station, which is an example of network infrastructure equipment / network access node, may also be referred to as a transceiver station, NodeB, eNodeB, gNodeB (gNB), etc. In this regard, different terms are often associated with different generations of radio communication systems for elements that provide broadly equivalent functionality. However, the exemplary embodiments of the present disclosure may be equally implemented in different generations of radio communication systems such as 5G and new radio as described below, and for the sake of brevity, specific terms may be used regardless of the underlying network architecture. That is, the use of specific terms in connection with some examples is not intended to limit those examples to a particular generation of network with which those specific terms may be most closely associated.

[0020] New Radio Access Technology (5G) FIG. 2 is a schematic diagram showing a network architecture for a new RAT wireless communication network / system 200 that may be adapted to provide the functions according to the embodiments of the present disclosure described herein. The new RAT network 200 shown in FIG. 2 includes a first communication cell 201 and a second communication cell 202. Each communication cell 201, 202 includes control nodes (central units) 221, 222 that communicate with a core network component 210 via respective wired or wireless links 251, 252. Also, each control node 221, 222 communicates with a plurality of distributed units (radio access nodes / remote transmit-receive points (TRPs)) 211, 212 within its respective cell. Again, these communications can be performed via respective wired or wireless links. The distributed units 211, 212 serve to provide a radio access interface for communication devices connected to the network. Each distributed unit 211, 212 has a coverage area (radio access footprint) 241, 242, and the overall coverage area of the distributed units under the control of the control node defines the coverage of the respective communication cells 201, 202. Each distributed unit 211, 212 includes a transceiver circuit for transmitting and receiving radio signals and a processor circuit configured to control the respective distributed units 211, 212.

[0021] Regarding the extensive top-level functions, the core network component 210 of the new RAT communication network represented in FIG. 2 may be broadly considered to correspond to the core network 102 represented in FIG. 1, and each control node 221, 222 and their associated distributed units / TRPs 211, 212 may be broadly considered to provide functions corresponding to the base station 101 in FIG. 1. The term network infrastructure equipment / access node may be used to encompass these elements and more conventional base station-type elements of a wireless communication system. Depending on the current application, the responsibility for scheduling transmissions scheduled on the radio interface between each distributed unit and the communication device may lie with the control node / central unit and / or the distributed unit / TRP.

[0022] In FIG. 2, a communication device / UE 260 is shown within the coverage area of the first communication cell 201. Thus, this communication device 260 can exchange signaling with the first control node 221 within the first communication cell 201 via one of the distributed units 211 associated with the first communication cell 201. In some cases, the communication for a given communication device is routed through only one of the distributed units, but it will be understood that in some other embodiments, the communication associated with a given communication device can be routed through more than one distributed unit, for example, in soft handover scenarios and other scenarios.

[0023] In the example of FIG. 2, two communication cells 201, 202 and one communication device 260 are shown for simplicity, but it will be understood that in reality, the system may include a greater number of communication cells (each supported by its respective control node and multiple distributed units) providing a greater number of communication devices.

[0024] FIG. 2 is merely an example of a proposed architecture for a new RAT communication system that may employ the techniques according to the principles described herein, and it should be further understood that the functions disclosed herein may be applied to wireless communication systems having different architectures.

[0025] Accordingly, the exemplary embodiments of the present disclosure described herein may be implemented in various different architectures of radio communication systems / networks, such as the exemplary architectures shown in FIGS. 1 and 2. Thus, it should be understood that the specific wireless communication architecture in any given implementation is not the most important for the principles described herein. In this regard, the exemplary embodiments of the present disclosure may be generally described in the context of communication between network infrastructure devices / access nodes and communication devices, and the specific nature of the network infrastructure devices / access nodes and communication devices depends on the network infrastructure for the current implementation. For example, in some scenarios, the network infrastructure device / access node may include a base station such as the LTE type base station 101 shown in FIG. 1, which is adapted to provide functions according to the principles described herein. In other examples, the network infrastructure device / access node may include control units / control nodes 221, 222 and / or TRPs 211, 212 of the type shown in FIG. 2, which are adapted to provide functions according to the principles described herein.

[0026] An exemplary network infrastructure device 272, which may correspond to a communication device such as communication device 260 in FIG. 2 or communication device 104 in FIG. 1, is shown in more detail in FIG. 3 as a combination of first and second UEs / communication devices 270a, 270b and an eNB (LTE base station) 101 or control node 221 and TRP 211. When there is no need to distinguish between the first communication device 270a and the second communication device 270b, it is denoted as communication device 270.

[0027] As shown in FIG. 3, the communication device 270 is configured to transmit uplink data to the infrastructure device 272 via an uplink resource of the wireless access interface, as schematically shown by an arrow 274 from the communication device 270 to the infrastructure device 272. Similarly, the communication device 270 may be configured to receive downlink data transmitted by the infrastructure device 272 via a downlink resource, as shown by an arrow 288 from the infrastructure device 272 to the communication device 270. Similar to FIGS. 1 and 2, the infrastructure device 272 is connected to the core network 276 via an interface 278 to a controller 280 of the infrastructure device 272. The infrastructure device 272 includes a receiver 282 connected to an antenna 284 and a transmitter 286 connected to the antenna 284. Correspondingly, each communication device 270 includes a controller 290 connected to a receiver 292 that receives signals from an antenna 294 and a transmitter 296 connected to the antenna 294.

[0028] The controller 280 is configured to control the infrastructure device 272 and may include a processor circuit. The processor circuit may in turn include various sub-units / sub-circuits for providing functions, as further described herein. These sub-units may be implemented as individual hardware elements or as functions appropriately configured in the processor circuit. Thus, the controller 280 may include a circuit appropriately configured / programmed to provide the desired functions using conventional programming / configuration techniques for devices in a wireless communication system. The transmitter 286 and the receiver 282 may include signal processing and radio frequency filters, amplifiers, and circuits according to conventional configurations. The transmitter 286, the receiver 282, and the controller 280 are schematically shown in FIG. 3 as separate elements for ease of representation. However, the functions of these elements may be provided in a variety of different ways, for example, using one or more appropriately programmed programmable computer(s), or one or more appropriately configured application specific integrated circuit(s) / circuit(s) / chip(s) / chip set(s). As will be appreciated, the infrastructure device 272 generally includes various other elements related to its operating functions.

[0029] Correspondingly, the controller 290 of each communication device 270 is configured to control the transmitter 296 and the receiver 292, and may include a processor circuit. The processor circuit may in turn include various sub-units / sub-circuits for providing functions, as further described herein. These sub-units may be implemented as individual hardware elements or as functions appropriately configured in the processor circuit. Thus, the controller 290 may include a circuit that is appropriately configured / programmed to provide the desired functions using conventional programming / configuration techniques for devices in a wireless communication system. Similarly, the transmitter 296 and the receiver 292 may include signal processing and radio frequency filters, amplifiers, and circuits according to conventional configurations. The transmitter 296, the receiver 292, and the controller 290 are schematically shown in FIG. 3 as separate elements for ease of illustration. However, it will be understood that the functions of these elements may be provided in a variety of different ways, for example, using one or more appropriately programmed programmable computer(s), or one or more appropriately configured application specific integrated circuit(s) / circuit(s) / chip(s) / chip set(s). As will be understood, the communication device 270 generally includes various other elements related to its operating functions, such as a power supply, a user interface, etc., which are not shown in FIG. 3 for the sake of brevity.

[0030] The controllers 280, 290 may be configured to execute instructions stored in a computer-readable medium such as a non-volatile memory. The processing steps described herein may be executed, for example, by a microprocessor together with a random access memory operating according to instructions stored in a computer-readable medium.

[0031] (Uplink cancellation indication) When a first communication device (such as communication device 104 in FIG. 1 or the first communication device 270a in FIG. 3) is allocated communication resources for the transmission of first data, some of these communication resources may then be allocated for the transmission of second data by a second communication device 270b. The selection of the communication resources associated with the latter allocation may be based on the quality of service (e.g., latency, priority) requirements associated with the second data.

[0032] FIG. 4 shows a scenario in which such a second allocation can be made.

[0033] FIG. 4 shows uplink communication resources 402 and downlink communication resources 404, which are provided simultaneously using radio access interfaces in different frequency ranges (i.e., using frequency division duplexing, FDD). Although the examples and embodiments described herein may use FDD, it should be understood that the technology is not limited thereto and may be used with other radio access interfaces such as those using time division duplexing (TDD).

[0034] In the example of FIG. 4, a first uplink grant 410 is transmitted by an infrastructure device (such as infrastructure device 272 in FIG. 3) at time t 1 . The first uplink grant 410 allocates a first communication resource 420 to the first communication device 270a for the transmission of first uplink data.

[0035] Then, at time t 3 , a second uplink grant 412 is transmitted by the infrastructure device 272. The second uplink grant 412 allocates a second communication resource 422 to the second communication device 270b for the uplink transmission of second uplink data. The second communication resource 422 includes at least a portion of the first communication resource 420, and such an allocation is referred to herein as "preemption" and results in a collision.

[0036] The second communication resource 422 may be allocated in response to the infrastructure device 272 determining that the second communication device 270b has uplink data for transmission. The transmission shall be completed by time t 7 up to, i.e., before the time t 8 at which the first communication resource 420 ends, (in accordance with the quality of service requirements related to the data). However, the reasons for allocating the second communication resource 420 are not limited to such scenarios, and it should be understood that the present disclosure is not so limited.

[0037] According to the prior art, the infrastructure device 272 may transmit an uplink cancellation indication (UL-CI) 430. The UL-CI 430 may indicate that some communication resources that have already been shown as being allocated as part of a particular first resource allocation are allocated as part of a subsequent second resource allocation after the first resource allocation. In some embodiments, the first resource allocation may be speculative, i.e., it may be performed by the infrastructure device 272 without determining that the target communication device of the first resource allocation has data for transmission using the allocated resources, or otherwise, it is possible to utilize the allocated resources. For example, the first resource allocation may be part of a periodic grant of resources, such as being performed by a set grant.

[0038] Generally, according to some embodiments of the technology of the present disclosure, the reasons for the indication of resources in the UL-CI 430 are not limited to such scenarios, and the resources may be indicated by the UL-CI 430 for any reason. For example, the resources may be indicated to reduce the level of uplink interference.

[0039] Therefore, the resources described in this specification as being "indicated" by the UL-CI may correspond to resources allocated to one or more communication devices and / or may correspond to resources that are not used by one or more recipients of the UL-CI but are required by the infrastructure device 272.

[0040] In any case, according to the prior art, in the example of FIG. 4, the purpose of the UL-CI 430 is to indicate to the first communication device 270a to which resources have been allocated by a first resource allocation that the first resource allocation is no longer valid and that the first communication device 270a should not transmit using some or all of the already allocated communication resources.

[0041] The UL-CI 430 may be transmitted within downlink control information (DCI), for example, by being transmitted using group common (GC) DCI and may be addressed to multiple communication devices. Thereby, communication devices other than the first communication device 270a can receive and process the UL-CI 430.

[0042] Therefore, the UL-CI 430 may include an indication of different resources that are indicated for different reasons, both in the prior art and in the various embodiments of the present technology. A communication device that receives the UL-CI 430 may not know the reason for which the resources are indicated. According to the prior art, a communication device that receives a UL-CI cancels its transmission if the indicated resources overlap with its transmission.

[0043] For example, as in the example of FIG. 4, the infrastructure device 272 may transmit a UL-CI 430 indicating resources that a communication device should refrain from using in order to avoid collisions resulting from competing subsequent resource allocations. The UL-CI 430 may alternatively or additionally indicate other resources for other reasons. In general, a communication device that receives a UL-CI may not know the reason for the indication of a particular resource in the UL-CI.

[0044] Similarly, since the UL-CI may be addressed to multiple communication devices, it may include an indication of resources not related to a specific communication device, but may affect the behavior of other communication devices.

[0045] Thus, in some embodiments of the present technology, a communication device may receive a UL-CI that indicates specific communication resources but does not indicate further information regarding the reason why those communication resources are indicated.

[0046] The communication device that detects and reads the UL-CI does not need to know the reason behind the indication, but needs to follow the instructions of the UL-CI. That is, if the uplink transmission of the communication device partially or completely overlaps with one or more of the sub-parts of the sub-part for which the uplink transmission is indicated, the communication device cancels that uplink transmission.

[0047] According to some prior arts, the UL-CI 430 may include an indication of communication resources, and the indicated communication resources include those allocated by both the first resource allocation and the second resource allocation.

[0048] A communication device that has received the UL-CI 430 and has already received an allocation of communication resources that fall within the indicated communication resources may refrain from transmitting using that resource allocation. The indicated communication resources may be indicated for preemption, but this (the reason for those indications) may not be indicated by the UL-CI, or alternatively, may not be determined by the communication device accordingly.

[0049] A specific example is shown in FIG. 5. In the example of FIG. 5, which may be according to some prior art, the UL-CI430 is transmitted according to a predetermined schedule. The UL-CI430 transmitted as shown in FIG. 5 is associated with a reference uplink region (RUR) 510. The RUR 510 is composed of one or more parts of the uplink communication resources. In the example of FIG. 5, the RUR 510 associated with the UL-CI430 is divided into 14 sub-parts 520a to 520n.

[0050] When the radio access interface is based on orthogonal frequency division multiplexing (OFDM) as in FIG. 5, each sub-part 520a to 520n may be extended in time over two OFDM symbol periods.

[0051] In the frequency domain, in FIG. 5, each sub-part 520a to 520g extends from frequency f 2 to f 3 and each sub-part 520h to 520n extends from frequency f 1 to f 2 Accordingly, the RUR 510 includes two rows within the frequency domain (M = 2) of each of the 7 sub-parts separated in the time domain (N = 7), and collectively extends over the frequencies from frequency f 1 to frequency f 3 and over the time from time t 2 to time t 7

[0052] According to some embodiments of the prior art and the techniques of the present disclosure, the UL-CI430 may indicate a sub-part (of the sub-parts 520a to 520n) that includes the resources subsequently allocated for the transmission of data by one or more communication devices and that (at least partially) overlaps (i.e., collides) with the resources allocated for the transmission of data by different communication devices.

[0053] ​The above indication may be made by bits in a bitmap (such as bitmap 530 shown in FIG. 5 included in UL-CI430). For example, a bit that is “1” may indicate that the sub-part includes the subsequently allocated resource, and “0” may indicate that the sub-part does not include the subsequently allocated resource.

[0054] In the example of FIG. 5, the subsequent resource allocation 540 fits within sub-parts 520h and 520i (shown with hatching in FIG. 5 with a different direction from other sub-parts of RUR510). At least a part of the subsequent resource allocation 540 overlaps with a previous resource allocation to a different communication device (not shown in the figure), and thus, the corresponding two bits of the bitmap 530 related to sub-parts 520h and 520i are set to “1”.

[0055] Therefore, when a communication device receiving UL-CI430 has communication resources allocated within (a plurality of) sub-parts of an RUR that are indicated as including the subsequently allocated resources according to its (previous) resource allocation, it can determine that a collision has occurred regarding the previous resource allocation.

[0056] A communication device may receive a UL-CI having one or more sub-parts indicating that it does not include any resources allocated to that communication device (for example, having corresponding bits in a bitmap set to “1”). Therefore, such a communication device may determine that the resources allocated to the communication device for data transmission have not been preempted, and thus, may transmit data using the allocated resources.

[0057] In the example of FIG. 5 and some embodiments of the present technology, the start of RUR510 occurs a predetermined duration T PROC after the end of the related UL-CI430.

[0058] It should be understood that the UL-CI430 does not have to accurately indicate which resources within the affected sub-part(s) are the targets of collisions, and there may be a risk of "false positives". A false positive can occur when a portion of the allocated resources falls within the boundaries of a sub-part indicated as containing a collision, but in fact does not overlap with other allocated resources and is therefore not part of the collision.

[0059] It should be understood that the number of sub-parts within the RUR510 is not limited to 14. In some embodiments, the number may be any of {1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 32, 35, 42, 56, 112}, and in some embodiments, it may be configurable by the infrastructure device 272.

[0060] According to the prior art, the bitmap may indicate all sub-parts that include the resources of subsequent (colliding) resource allocations. However, in some embodiments of the present technology, the bitmap indicates only the sub-parts that include the (multiple) portions that overlap with the previous resource allocation among the colliding resource allocations.

[0061] According to the prior art, the communication device may execute a process as shown by the flowchart of FIG. 6.

[0062] The process starts at step S602 when the communication device receives an allocation of a first uplink communication resource. In response to receiving the allocation, the communication device may start the preparation steps necessary to be able to transmit data using the first uplink communication resource. These preparation steps may continue during subsequent steps in the process. Next, the process proceeds to step S604.

[0063] In step S604, the communication device determines whether it has reached the start time of the first uplink communication resource. If it has reached, the process proceeds to step S606, and the communication device transmits data using the first uplink communication resource. This may correspond to the case where the UL-CI that causes the communication device to determine not to transmit data using the first uplink communication resource has not been received before the start time of the allocated resource.

[0064] According to some prior arts, the process may end at step S606.

[0065] However, according to some prior arts, the communication device may determine whether it has received a UL-CI while transmitting data. If it has received, the determinations in steps S608, S610, and S612 may be made as described below. As a result of such determinations, if the communication device reaches step S614 during transmission, the transmission may end.

[0066] If it has not reached the start time of the first uplink communication resource, the process proceeds to step S608. In step S608, the communication device determines whether it has received a UL-CI. If it has not received, the process returns to step S604. The determinations in steps S604 and S606 may be continuously or periodically repeated until an affirmative determination is made in one of these steps.

[0067] If the communication device has received a UL-CI, the control proceeds to step S610. In step S610, the communication device determines whether any part of the first uplink communication resource is within the RUR associated with the UL-CI. If a part of the first uplink communication resource is not within the RUR associated with the UL-CI, the process returns to step S604. Otherwise, the process proceeds to step S612.

[0068] In step S612, the communication device determines whether the UL-CI indicates that any part of the first uplink communication resource is within the indicated sub-part of the RUR associated with the UL-CI. As described above, the UL-CI can indicate such a resource. This is because these resources include resource allocations that preempt previous resource allocations.

[0069] If none of the first uplink communication resources are within the indicated sub-part, the process returns to step S604. Otherwise (i.e., if some or all of the first uplink communication resources are within one or more of the indicated sub-parts), the process proceeds to step S614 and the communication device ends without transmitting using the first uplink communication resource.

[0070] Thus, according to the prior art, the communication device may cancel the transmission and refrain from transmitting using the allocated uplink communication resource, for example, if the allocated communication resource is also allocated for a different transmission.

[0071] According to some embodiments of the prior art and the technology of the present disclosure, after ending the process of FIG. 6 without transmitting data, if the conditions for transmitting data using other allocated resources are satisfied (for example, if step S606 is reached for those resources), the communication device may transmit the data using those other allocated resources.

[0072] The process of a later allocation using a communication resource previously allocated by an earlier allocation is referred to herein as "preemption". It is recognized that preemption can occur with respect to allocations made for different communication devices ("inter-UE preemption") and with respect to allocations made for a single communication device ("intra-UE preemption").

[0073] The communication device may be configured to monitor UL-CI transmissions and selectively cancel uplink transmissions based on the indication of resources in the monitored UL-CI when the indicated resources overlap with the resources allocated for uplink transmission (e.g., by an infrastructure device). In particular, a communication device that transmits only low-priority data or data that can be transmitted with high latency can pre-empt the resources allocated for the transmission of such data, and thus may be configured to monitor UL-CI and respond to UL-CI.

[0074] On the other hand, for example, a communication device that performs high-priority transmissions and / or very low-latency transmissions may be configured not to monitor or respond to UL-CI since high-priority transmissions or low-latency transmissions are not pre-empted.

[0075] However, it has been recognized that the communication device may be configured to monitor and read UL-CI and to transmit data such that the allocation for the transmission of such data pre-empts the previous resource allocation.

[0076] UL-CI may be broadcast or multicast to multiple communication devices, and it has been recognized that for the indicated sub-parts, it does not identify which resource allocation is the previous allocation that is actually pre-empted and which resource allocation is the (subsequent) pre-emptive allocation that causes a collision. In the case of a collision between the resources allocated to a first communication device (initially) and the resources allocated to a second communication device (subsequently causing the collision), a UL-CI indicating the resulting collision may be transmitted.

[0077] If the second communication device is configured to monitor and respond to the UL-CI, the second communication device cancels its uplink transmission even if, in accordance with the prior art described above, the allocation of resources for that transmission which resulted in the transmission of the UL-CI indicated the resources allocated to the second communication device. This may occur in addition to the cancellation of that transmission by the first communication device. Thus, neither communication device transmits, and communication resources may be wasted.

[0078] Referring to the example illustrated in FIG. 4, since both the first communication device 272a and the second communication device 272b are configured to monitor the resources used for the transmission of the UL-CI 430, both the first communication device 272a and the second communication device 272b may receive the UL-CI 430. Since the UL-CI 430 indicates resources that are part of the first communication resource 420 (for example, the resource 422 corresponding to the second resource allocation), the first communication device 272a determines that it should refrain from transmitting using the first communication resource 420.

[0079] However, since the UL-CI 430 indicates resources that are part of the second communication resource 422, the second communication device 272b also determines that it should refrain from transmitting using the second communication resource 420.

[0080] Thus, while the UL-CI 430 allows the second communication device 272b to transmit low-latency data without causing uplink interference due to duplicate transmission by the first communication device 272a, it may have the unintended effect of causing the second communication device 272b to refrain from transmitting using the second communication resource 422.

[0081] Therefore, it is necessary to solve this "false positive" reaction to the UL-CI.

[0082] Embodiments of the present technology are methods for operating a communication device in a wireless communication network, comprising receiving an uplink grant indication at a first time, the uplink grant indication indicating a first uplink communication resource allocated for transmission of first data by the communication device, receiving an uplink cancellation indication (UL-CI) at a second time, the UL-CI indicating a second uplink communication resource, the second uplink communication resource including at least a part of the first uplink communication resource, and in response to receiving the uplink grant indication and the uplink cancellation indication, determining whether to transmit the first data using the first uplink communication resource based on the first time and the second time.

[0083] In particular, some embodiments of the present technology are methods for operating a communication device in a wireless communication network, comprising receiving an uplink grant indication, the uplink grant indication indicating a first uplink communication resource allocated for transmission of first data by the communication device, receiving an uplink cancellation indication (UL-CI) at a second time, the UL-CI indicating a resource within a reference uplink region, the reference uplink region being associated with the UL-CI and defining an uplink communication resource, determining that the first uplink communication resource is within the resource indicated by the UL-CI, determining a time window associated with the UL-CI, determining that the uplink grant indication is received within the time window associated with the UL-CI, and in response to determining that the uplink grant indication is received within the time window associated with the UL-CI, transmitting the first data using the first uplink communication resource.

[0084] Therefore, the communication device may be configured to ignore the received UL-CI if the uplink grant is received within the time window associated with the UL-CI, and may transmit using the allocated uplink resources even if the UL-CI indicates some or all of the allocated uplink resources.

[0085] Embodiments of the present technology can avoid the need for additional information to be transmitted within the UL-CI.

[0086] Embodiments of the present technology may also be independent of other priority indications (such as physical layer priority) that are intended for prioritizing data or resources within the same communication device. Thus, embodiments of the present technology can be applied when no priority indication is provided for, or when the priorities are equal for, the prioritization within the communication device for data transmitted using conflicting communication resources (or the communication resources themselves).

[0087] According to some embodiments of the present technology, a communication device that receives a UL-CI determines the time window associated with the UL-CI. If the communication device additionally receives a grant for uplink communication resources, the grant is received within the time window, and then those uplink communication resources are used for data transmission regardless of any indication applicable to those resources within the UL-CI. In some embodiments, if the grant is received outside the time window and the UL-CI indicates some or all of the allocated resources, the communication device does not transmit using the allocated resources.

[0088] In some embodiments, if two UL-CIs are received, both scenarios may occur with respect to the same grant, where the grant is within the window associated with one UL-CI and outside the window of the other UL-CI.

[0089] FIG. 7 shows an example of transmission according to some embodiments of the present technology.

[0090] Time t 0 to time t 1 During the period from, the infrastructure device 272 transmits the first uplink grant 702 to the first communication device 270a and allocates the first uplink communication resource 722 extending from time t 5 to time t 9 until.

[0091] Next, the infrastructure device determines that the second uplink resource 724 is allocated to the second communication device 270b. In response, the infrastructure device transmits the second uplink grant 704 that allocates the second uplink communication resource 724 to the second communication device 270b (as shown by the first arrow 714) during the period from time t 2 to time t 3 until.

[0092] The infrastructure device 272 determines that the first communication resource 722 and the second communication resource 724 partially overlap. If both the first communication device 270a and the second communication device 270b transmit using their respective allocations, it is likely that the infrastructure device 272 will not accurately decode the data transmitted by the first and second communication devices 270a and 270b.

[0093] The data transmitted by the second communication device 270b may have service quality requirements for low latency and / or high-priority transmission compared to the service quality requirements for the data transmitted by the first communication device 270a.

[0094] Therefore, in order to indicate to the first communication device 270a that it should refrain from transmitting using the first communication resource 722, the infrastructure device 272, during the period from time t 3 to time t 4Before that, an uplink collision indication (UL-CI) 732 is transmitted.

[0095] In the example of FIG. 7, the UL-CI is formed according to the prior art described above with respect to the example of FIG. 5. That is, the UL-CI 732 is associated with the RUR 742 divided into sub-parts. The UL-CI 732 includes a bitmap 752, and one bit is associated with each sub-part of the RUR 742. For each sub-part where the resources of the first communication resource 722 and the resources of the second communication resource 724 overlap, the corresponding bit in the bitmap 752 is set to "1". Alternatively, in some embodiments, if the sub-part includes any part of the second communication resource 724, the bit corresponding to the sub-part is set to "1" (i.e., the sub-part is "indicated"). However, in this case, it will be understood that the indicated sub-part includes one or more sub-parts where the first communication resource 722 and the second communication resource 724 overlap.

[0096] In the example of FIG. 7, the UL-CI 732 is 2 from time t 6 to time t UL-CI and is associated with the time window W extending thereto. Regardless of the content of the UL-CI 732, any communication device (such as the communication device 270b) that receives an uplink grant (such as the second uplink grant 704, etc.) transmitted during this time window should refrain from transmitting data using the granted resources according to the embodiments of the present technology based on the UL-CI 732.

[0097] In the example of FIG. 7, both the first communication device 270a and the second communication device 270b receive the UL-CI 732. This may be because, according to some embodiments of the present technology, both are configured to monitor the downlink communication resources for UL-CI transmission including the resources used for transmitting the UL-CI 732. In some embodiments, the downlink communication resources monitored according to this configuration are periodic.

[0098] In the example of FIG. 7, according to some embodiments of the present technology, time window W UL-CI starts with a duration T 3 before the start of the transmission of UL-CI732 at time t BEFORE and, as a result, the time window starts at time t 2 .

[0099] In the example of FIG. 7, according to some embodiments of the present technology, time window W UL-CI ends T 4 duration after the end of the transmission of UL-CI732 at time t AFTER and, as a result, the time window ends at time t 6 .

[0100] The first communication device 270a determines that at least a part of the first communication resource 722 is included in the sub-part indicated by the bitmap 752 based on UL-CI732 (and specifically, in the example of FIG. 7, based on the bitmap 752). Since the first uplink grant 702 is received outside the time window W UL-CI , the first communication device 270a cancels its transmission and refrains from transmitting using the first communication resource 722.

[0101] The second communication device 270b may determine that at least a part of the second communication resource 724 is within the sub-part indicated by the bitmap 752 based on UL-CI732. However, since the second uplink grant 704 is received within the time window W UL-CI , the second communication device 270b does not cancel its transmission and transmits using the second communication resource 722. In some embodiments of the present technology, the second communication device 270b may transmit using the second communication resource 722 only when UL-CI satisfying both of the following conditions is not received. At least a part of the second communication resource 724 is within the sub-part indicated by the UL-CI, and The second uplink grant 704 was received outside the time window associated with the UL-CI.

[0102] Thus, embodiments of the present technology can prevent a communication device from canceling transmission in response to a UL-CI sent for the purpose of notifying different communication devices of restrictions applicable to the indicated communication resources (e.g., as a result of a collision). In some embodiments, the time window W UL-CI for determining may be determined in advance so that no additional information is required within the UL-CI itself (e.g., set by RRC configuration, specified in the standard, or signaled in any suitable way such as broadcast information).

[0103] In some embodiments, the time window W UL-CI starts before the time when the UL-CI is transmitted. In other words, as shown in the example of FIG. 7, T BEFORE is greater than 0. Thus, the uplink grant corresponding to the second communication resource (i.e., the uplink grant that causes a collision) may be transmitted before the corresponding UL-CI transmitted by the infrastructure device, for example, in response to an overlapping allocation. This enables the second communication device to start steps such as encoding with respect to data transmitted using the second communication resource before the UL-CI is transmitted. Also, considering that UL-CI transmission is restricted according to a predetermined setting and can occur at a relatively low frequency (i.e., high periodicity between UL-CI transmission opportunities), it is possible to provide flexibility in the transmission of uplink grants.

[0104] In some embodiments, T BEFOREis zero, that is, the time window does not start before the time when the UL-CI is transmitted. Thus, in such an embodiment, a communication device that receives the UL-CI after receiving the uplink grant may refrain from processing the UL-CI and using the communication resources allocated by the uplink grant if indicated by the UL-CI.

[0105] In some embodiments, the time window W UL-CI may end at a time corresponding to the earliest time related to the communication resources that may be indicated by the UL-CI. For example, if the UL-CI is associated with the RUR, the time window W UL-CI may end at the start time corresponding to the resources of the RUR.

[0106] FIG. 8 shows an example of transmission according to some embodiments of the present technology where T BEFORE is zero and the time window W UL-CI ends at the start time corresponding to the resources of the RUR.

[0107] In the example of FIG. 8, the first uplink grant 802 allocates the first communication resource 822, and the second uplink grant 804 allocates the second communication resource 824. Since the second communication resource 824 overlaps with the first communication resource 822, the sub-part of the RUR 842 including the second communication resource 824 is indicated by the UL-CI 832 by the bitmap 852. Since the first uplink grant 802 is transmitted outside the time window W UL-CI , the first communication device 270a processes the UL-CI 832, confirms that the first communication resource 822 fits into the sub-part of the RUR shown to have the resources allocated by the pre-emptive resource allocation inside it, and refrains from transmitting using the first communication resource 822.

[0108] Both the second uplink grant 804 and the UL-CI 832 are from time t 2 to time t 3Since it was transmitted before, the second uplink grant 804 starts at time t 2 and ends within a time window W 4 (start time of RUR842) that starts at time t UL-CI and is transmitted and received within. Therefore, the second communication device 270b ignores the UL-CI832 as far as the second communication resource 824 is concerned and uses the second communication resource 824 to transmit data.

[0109] In some embodiments, the respective RURs associated with different UL-CIs may overlap. Therefore, a particular communication resource may be indicated by two or more UL-CIs. According to some embodiments of the present technology, the communication device processes each UL-CI independently by determining the following for each UL-CI. Whether the UL-CI indicates an uplink communication resource assigned by an uplink grant for data transmission by the communication device, and Whether the uplink grant was received within the time window W UL-CI associated with the UL-CI.

[0110] In some embodiments, if the uplink grant is received outside the time window W UL-CI associated with any UL-CI that indicates such a resource, the communication device refrains from transmitting data using the uplink communication resource.

[0111] Therefore, embodiments of the present technology can provide transmission of a UL-CI that restrains a communication device from using the allocated communication resources even when another UL-CI indicating a resource (which may be a resource corresponding to a collision) is ignored by the communication device. Thus, in some embodiments, a later UL-CI can override an earlier UL-CI with respect to the same communication resources and the same communication device. In some such embodiments, the infrastructure device 272 may rely on this principle such that a communication resource whose allocation causes a collision as a result of preemption is then preempted by yet another resource allocation.

[0112] FIG. 9 shows an example of transmission according to some embodiments of the present technology.

[0113] In the example of FIG. 9, a first communication resource 922 and a second communication resource 924 are respectively allocated by first and second uplink grants 902 and 904. At time t 2 to time t 3 both the second uplink grant 904 and the first UL-CI 932 are transmitted. In the case of the first UL-CI 932, the second uplink grant 904 is within the associated first time window W UL-CI#1 Therefore, when determining whether to transmit data using the resources allocated by the second uplink grant 904, the second communication device 270b ignores the first UL-CI 932.

[0114] Furthermore, for example, subsequently (not shown in FIG. 9), a further (third) resource allocation is made that includes a third communication resource within a subportion bounded by frequencies f 1 and f 3 as well as times t 8 and t 9 The frequencies are f 1 and f 3 as well as times t 8 and t9 Within the sub - portion bounded by 9 , the third communication resource collides with (i.e., overlaps with) a part of the second communication resource 924. In response, the infrastructure device 272 transmits the second UL - CI934 between time t 4 and time t 5 . The first and second UL - CIs are associated with their respective first and second RURs 942 and 944 and include their respective first and second bitmaps 952 and 954. The first RUR 942 and the second RUR 944 comprise resources spanning the frequency domain from frequency f 1 to frequency f 3 . In the time domain, the first RUR 942 extends from time t 5 to time t 10 , and the second RUR 944 extends from time t 8 to time t 11 .

[0115] The first bitmap 952 indicates the sub - portion of the first RUR 942 that includes the second communication resource 942. The second bitmap 954 indicates the sub - portion of the second RUR 944 that includes the third communication resource.

[0116] Since the second uplink grant 904 is outside the time window W UL-CI#2 associated with the second UL - CI934, the second communication device 270b processes the second bitmap 954, determines that the indicated sub - portion includes at least a part of the second communication resource 924, and refrains from transmitting using the second communication resource 924.

[0117] In the example of FIG. 9, the first and second bitmaps 952 and 954 are marked with a "1" to indicate those sub - portions that include part of a subsequent resource allocation, where the subsequent resource allocation overlaps (and thus preempts) a previous resource allocation. Thus, the first and second bitmaps 952 and 954 include bits set to "1" corresponding to (i.e., "indicating") sub - portions that include part of a subsequent resource allocation but none of the previous resource allocations.

[0118] In some embodiments, the UL - CI may indicate only sub - portions that include both part of a subsequent resource allocation and part of a previous resource allocation. For example, referring to FIG. 9, in some embodiments, the first bitmap 952 may indicate only the sub - portion that includes the overlap between the first and second communication resources 922 and 924, i.e., {0000000;0011000}. Similarly, the second bitmap 954 may indicate only the sub - portion that includes the overlap between the second communication resource 924 and the third communication resource, i.e., {0000000;1000000}. However, as described above, according to some embodiments, the resources indicated by the bitmaps in the UL - CI are not limited to resources related to collisions and may be indicated by the infrastructure device for other reasons. In particular, in some embodiments, the communication device may not have to determine any reason for the indication of resources in the UL - CI.

[0119] As described above and as shown, for example, in FIG. 7, in some embodiments, the end of the time window W UL-CI may be determined to be a predetermined duration T AFTER after the end of the resources used to transmit the UL - CI.

[0120] In some embodiments, the time window W UL-CIThe end may be determined based on the start time or end time of the resource corresponding to the RUR associated with the UL-CI. For example, as shown in FIG. 8 and as described above, in some embodiments, the time window ends at the start of the RUR. In the example of FIG. 8, for UL-CI 832, the associated time window W UL-CI ends at the time t 4 which is the start of the RUR 842 of UL-CI 832.

[0121] In some embodiments, the time window associated with the UL-CI ends at the end of the corresponding RUR. Thus, in some embodiments, the uplink grant may be transmitted after the start of the RUR associated with a previously transmitted UL-CI. An example of such a transmission is shown in FIG. 10.

[0122] In the example of FIG. 10, the first communication resource 1022 is allocated for the transmission of data by the first communication device 270a by the first uplink grant 1002 transmitted between time t 0 and time t 1 .

[0123] Separately (e.g., after time t 1 ), the infrastructure device 272 allocates the second communication resource 1024 for the transmission of data by the second communication device 270b. Between time t 3 and time t 4 , the infrastructure device 272 transmits a first UL-CI 1032 having an associated RUR 1042 that extends in time from time t 5 to time t 11 . Thus, the time window W UL-CI associated with the first UL-CI 1032 extends to time t 11 which is the end of the RUR 1042. The UL-CI 1032 indicates, by a bitmap 1052, the sub-portions where the first and second communication resources 1022 and 1024 collide.

[0124] The time window W UL-CISince it extends after the transmission of UL-CI1032, the transmission of the uplink grant for the second communication resource 1024 does not need to be performed before or at the same time as the transmission of UL-CI1032.

[0125] Similar to some embodiments of the present technology, the first UL-CI1032 may be transmitted according to a predetermined schedule for UL-CI transmissions monitored by the first and second communication devices 270a and 270b.

[0126] The infrastructure device 272 transmits a second uplink grant 1004 for indicating the allocation of the second communication resource 1024 to the second communication device 270b between time t 5 and time t 6 Since the second uplink grant 1004 is within the time window W UL-CI associated with the first UL-CI1032, the second communication device 270b does not refrain from transmitting data using the second communication resource 1024.

[0127] Conversely, since the time window W UL-CI associated with the first UL-CI1032 starts at time t 2 after the transmission of the first uplink grant 1002, the first communication device 270a determines to refrain from transmitting using the first communication resource 1022 because the bitmap 1052 indicates a sub-part that includes some or all of the first communication resource 1022.

[0128] Therefore, the embodiments of the present technology can provide flexibility when selecting the time at which the uplink grant for allocating the previously allocated resources is transmitted.

[0129] In the example of FIG. 10, the second UL-CI1034 is from time t 7 to time t 8It is transmitted before. Although not shown in FIG. 10, the time window associated with the second UL-CI 1034 starts at the time t when the transmission / reception of the second uplink grant 1004 ends 6 or later. Thus, according to some embodiments, the second communication device 270b is applicable to the second communication resource 1024 allocated by the second uplink grant 1004 and follows any indication of the resources indicated by the second UL-CI 1034 (e.g., refrains from transmitting using the allocated resources).

[0130] In some embodiments, the time window associated with the UL-CI does not end (in other words, T AFTER = ∞). In such embodiments, the UL-CI transmitted before the uplink grant does not need to be considered when determining whether to use the resources allocated by the uplink grant for data transmission, regardless of the time between the transmission of the UL-CI and the uplink grant.

[0131] In some embodiments, the time window associated with the UL-CI ends at the end of the transmission of the UL-CI. That is, T AFTER = 0.

[0132] As described above, in some embodiments, the infrastructure device transmits the UL-CI to be monitored by the communication device only at a specific time, for example, according to a predetermined schedule of possible transmission instances known to the communication device. Such embodiments can reduce the amount of monitoring required for UL-CI transmission by the communication device.

[0133] The transmission instance may be referred to as a monitoring opportunity. The UL-CI may be transmitted using prior art for the transmission of downlink control information (DCI) and, optionally, may be transmitted in any particular monitoring opportunity. The communication device is required to receive and detect any UL-CI transmitted in a monitoring opportunity according to a predetermined schedule, but the infrastructure device may refrain from transmitting the UL-CI in a monitoring opportunity in some embodiments, for example, if no preemption occurs with respect to the resources within the RUR associated with the UL-CI.

[0134] In some such embodiments, the time window associated with the UL-CI transmitted in the first monitoring opportunity ends at the start of the next transmission instance after the first monitoring opportunity.

[0135] FIG. 11 shows an example of a transmission including a UL-CI and an associated time window that ends at the start of the next UL-CI monitoring opportunity according to some embodiments of the present disclosure.

[0136] The transmission shown in FIG. 11 is the same as the transmission shown in FIG. 10. However, in the example of FIG. 11, the UL-CI monitoring opportunity starts at time t 3 and time t 7 and the time window associated with the UL-CI ends at the start of the next monitoring opportunity as described above.

[0137] Thus, the time window associated with the first UL-CI 1032 ends at time t 7

[0138] In some embodiments, the communication device determines time window determination parameters to determine the time window associated with the UL-CI. In some embodiments, the time window determination parameters include one or more of the following. T BEFORE , T AFTER , ​Whether the end of the time window coincides with the start or end of the associated RUR, and Whether the end of the time window coincides with the start of the next UL-CI monitoring opportunity according to the UL-CI transmission schedule.

[0139] In some embodiments, one or more of the time window determination parameters are statically set in the communication device (e.g., at manufacture or by a software update). The time window determination parameters may be defined in an appropriate standard specification. Thus, no signaling of the time window determination parameters may be required.

[0140] In some embodiments, one or more of the time window determination parameters are set in the communication device by radio resource control configurations or other configuration means provided in a protocol layer above the media access control layer. Thus, embodiments of the present technology can provide flexible configuration of parameters.

[0141] In some embodiments, an indication of one or more of the time window determination parameters is transmitted to the communication device by signaling in the media access control layer or a lower protocol layer. For example, the parameters may be signaled within downlink control information (DCI). In some embodiments, the DCI containing the indication of the parameters may also include an uplink grant or UL-CI. Thus, embodiments of the present technology can provide dynamic configuration of parameters.

[0142] As described above, embodiments of the present technology can make the UL-CI selectively applicable to different uplink grant indications according to the relative transmission time between the UL-CI and the uplink grant.

[0143] However, this may impose some constraints on the scheduling of the uplink grant to ensure that one (effectively canceled by the UL-CI) is outside the time window of the UL-CI and the other is not.

[0144] FIG. 12 shows an example of a scenario where two uplink grants are temporally separated but are both treated equally nonetheless.

[0145] In FIG. 12, the first and second communication resources 1222 and 1224 are allocated as in the example of FIG. 11, and UL-CI 1232 is transmitted by bitmap 1252 to indicate a sub-part of RUR 1242 associated with UL-CI 1232, and the indicated sub-part is a sub-part that includes overlapping resources.

[0146] Unlike the example of FIG. 11, in FIG. 12, the first uplink grant 1202 and the second uplink grant 1204 are transmitted at times t 1 and t 2 respectively, and times t 1 and t 2 are both within the time window W UL-CI associated with UL-CI 1232. The reason for the transmission timing of the first and second uplink grants 1202 and 1204 may be, for example, that there is no availability of other suitable communication resources for transmitting the uplink grants 1202 and 1204. In some embodiments, in order for the communication device to prepare data for transmission (e.g., by performing an encoding step) in response to an uplink grant and to provide sufficient time to prepare a transmission circuit for data transmission using the allocated communication resources, the infrastructure device may determine that the uplink grant must be transmitted such that the time between the transmission of the uplink grant and the start of the resources allocated by the uplink grant exceeds a predetermined duration.

[0147] Both the first and second uplink grants 1202 and 1204 are within the time window W UL-CISince the first and second uplink grants are transmitted within the first and second communication resources 1222 and 1224, respectively, both the first and second communication devices 270a and 270b (subject to the first and second uplink grants, respectively) do not refrain from transmitting using the first and second communication resources 1222 and 1224 (respectively). This is not a desired outcome in this example, since the transmissions of both communication devices 270a and 270b would likely result in a collision and the infrastructure equipment 272 would fail to decode one or both transmissions.

[0148] Both the first and second uplink grants 1202 and 1204 are within the time window W associated with UL-CI 1232. UL-CI For example, in the example in Figure 12, T BEFORE = 0, and the time window W UL-CI is time t 3 Further problems may arise because starting at 1222, both communications devices 270a and 270b cancel transmission and reception using the first and second uplink communications resources 1222 and 1224.

[0149] According to some embodiments of the present technology, the infrastructure device 272 transmits two uplink grants for the same communication resource to the same communication device and also transmits a UL-CI indicating the communication resource. In some embodiments, the two uplink grants indicate consistent parameters such as coding parameters, block size, etc., and thus any (plural) coding process initiated in response to the first uplink grant of the two uplink grants is consistent with (i.e., conforms to) any parameters indicated by the second uplink grant of the two uplink grants. In some embodiments, the second (later) uplink grant includes fewer parameters. For example, the second uplink grant can include an indicator indicating that the first (earlier) grant has been acknowledged. The indicator is, for example, a 1-bit indicator for either acknowledging or not acknowledging the transmission of the first (earlier) uplink grant.

[0150] One of the uplink grants is transmitted within a time window associated with the UL-CI. In particular, one of the uplink grants transmitted within the time window is the second uplink grant of the two uplink grants.

[0151] Thus, the communication device receives a first uplink grant indicating the allocated communication resource. In response to receiving the first uplink grant, the communication device may initiate a preparation step for transmitting data using the allocated communication resource. Next, the communication device receives a UL-CI indicating the allocated communication resource (or a part thereof), and the first uplink grant is received outside the time window associated with the ULCI.

[0152] The communications device receives a second uplink grant during a time window associated with the UL-CI that allocates the same communications resources as allocated by the first uplink grant. In response to receiving the second uplink grant and determining that it was received during the time window associated with the UL-CI, the communications device determines that it should not refrain from transmitting using the allocated communications resources, regardless of the resources indicated by the UL-CI.

[0153] An example is shown in Figure 13.

[0154] FIG. 13 shows the same resource allocation as the example in FIG. 12. However, in the example in FIG. 13, the time window W associated with UL-CI1232 UL-CI Within time t 5 An additional (third) uplink grant 1306 is transmitted at 1224. The third uplink grant 1306 allocates the second communications resources 1224 to the second communications device 270b, i.e., allocates the same resources to the communications device as the second uplink grant 1204.

[0155] The first uplink grant 1202 is within the time window W associated with UL-CI1232. UL-CI Because the signal is received outside (before) the first communication device 270a, the first communication device 270a follows the instructions of the first communication resource 1222 (or a portion thereof) as indicated by the bitmap 1252 in the UL-CI 1232 and refrains from transmitting data using the first communication resource 1222.

[0156] Meanwhile, the second communication device is connected to the UL-CI1232 associated time window W UL-CI In response, the second communications device receives a third uplink grant 1306 received in the UL-CI 1232. In response, the second communications device determines that it should not follow the instruction of the second communications resource 1224 (or a portion thereof), as indicated by the bitmap 1252 in the UL-CI 1232, and transmits data using the second communications resource 1224.

[0157] Thus, embodiments of the present technology can enable an infrastructure device to transmit an uplink grant early enough for a communication device to complete the necessary preparations for transmission, and can indicate that the UL-CI does not apply to the communication device (i.e., can be ignored by the communication device) with respect to the allocated resources.

[0158] According to some embodiments of the present technology, in response to receiving a second uplink grant 1204, a communication device performs steps for preparing to transmit data using a second uplink communication resource 1224, and a third uplink grant 1306 indicates parameters for data transmission that match these preparation steps (e.g., the modulation and coding schemes, transport block sizes, etc. indicated by the second uplink grant 1204 and the third uplink grant 1306 do not conflict), or the third uplink grant provides an indicator (e.g., a 1-bit indicator) indicating whether to proceed with transmission using the second uplink communication resource. Thus, embodiments of the present technology may mean that the third uplink grant 1306 does not need to be received significantly earlier than the second uplink communication resource 1224 for the communication device to complete the necessary preparation steps (such as encoding) between receiving the third uplink grant 1306 and starting the second uplink communication resource 1224. In particular, this can be beneficial when, in the absence of the third uplink grant 1306, the communication device would refrain from transmitting using the second uplink communication resource 1224.

[0159] In some embodiments, (as in the example of FIG. 13) the third uplink grant 1306 must be received within a time window W associated with the UL-CI 1232. UL-CI must be received within.

[0160] In some embodiments, the third uplink grant starts at (further or instead of) the end of reception of the UL-CI, and must be received within a confirmation time window having a duration T. confirm The duration T confirm may be defined such that the confirmation time window ends before the start of the allocated communication resources. Thus, the duration T DCI may be different for different communication devices according to the start time of each allocated communication resource. The duration T confirm may be the minimum duration required for the communication device to respond to the reception of the third uplink grant. The duration T DCI is specified in the standard or may be set in the communication device 270 by RRC configuration or other known techniques. DCI

[0161] FIG. 14 shows a transmission according to embodiments of the present technology, showing the transmission of an uplink grant within a confirmation time window.

[0162] The transmission in the example of FIG. 14 is the same as the transmission in the example of FIG. 13. However, in the example of FIG. 14, T BEFORE is greater than zero. The communication devices 270a and 270b have different respective decisions regarding whether to transmit using the allocated resources 1222 and 1224.

[0163] Specifically, the first communication device 270a receives a first uplink grant 1202 that allocates a first uplink resource 1222 and a UL-CI 1232. The first uplink communication resource 1222 starts at time t 7 . Thus, the first communication device 270a determines that the confirmation time window associated with the UL-CI 1232 extends from time t 4 (when the reception of the UL-CI 1232 ends) to time t 5 . Here, time t 5is the time t when the first uplink communication resource 1222 starts 7 is a predetermined duration T DCI earlier than that time.

[0164] The first uplink grant 1202 is received within the time window W associated with the ULCI 1232 UL-CI Since no further uplink grants are received within the acknowledgment time window, the first communication device 270a refrains from, for example, processing the UL-CI 1232 in a conventional manner and transmitting using the first communication resource 1222.

[0165] In some embodiments, regardless of the time at which the first uplink grant 1202 is received, the first communication device 270a refrains from transmitting using the first communication resource 1222 in response to determining that no further uplink grants are received within the acknowledgment time window. In some such embodiments, the time window W associated with the UL-CI 1232 UL-CI may not exist.

[0166] Alternatively, in some embodiments (not shown in FIG. 14), in response to determining that no further uplink grants are received within the acknowledgment time window and that the first uplink grant 1202 is not received within the time window W associated with the UL-CI 1232 UL-CI the first communication device 270a refrains from transmitting using the first communication resource 1222.

[0167] Conversely, the second communication device 270b receives a second uplink grant 1204 that allocates a second uplink resource 1224 and the UL-CI 1232. The second uplink communication resource 1224 starts at time t 10 Accordingly, the second communication device 270b determines that the acknowledgment time window associated with the UL-CI 1232 extends from time t 4 (when the reception of the UL-CI 1232 ends) to time t 8 Here, time t8 is the time t 10 earlier than T DCI is the previous time.

[0168] Since the third uplink grant 1306 is received during the confirmation time window for confirming the allocation of the second communication resource 1224 to the second communication device 270b, the second communication device 270b ignores the UL-CI 1232 and uses the second communication resource 1222 to transmit data.

[0169] Therefore, embodiments of the present technology can provide a method of transmitting a confirmation uplink grant after a UL-CI received at least a predetermined duration before the allocated uplink resource.

[0170] In some embodiments, the communication device may receive two UL-CIs with associated RURs, and at least a portion of the communication resources allocated to the communication device by the uplink grant falls within both RURs.

[0171] According to some embodiments, the communication device refrains from transmitting using the allocated resources only if both UL-CIs indicate some of the allocated communication resources. The indicated communication resources may differ between UL-CIs. The associated RURs may be the same or different.

[0172] An example of such an embodiment is shown in FIG. 15.

[0173] In the example of FIG. 15, the first and second communication resources 1522 and 1524 are allocated to the first and second communication devices 270a and 270b by the first and second uplink grant instructions 1502 and 1504, respectively.

[0174] The first and second UL-CIs 1532 and 1534 are also transmitted and received by both the first and second communication devices 270a and 270b. Each UL-CI 1532, 1534 is associated with its respective RUR 1542 and 1544 and includes respective bitmaps 1552 and 1554 indicating sub-parts of the RUR, where the indicated sub-parts include resources of colliding resource allocations.

[0175] In the frequency domain, the first RUR 1542 and the second RUR 1544 extend from frequency f l to frequency f 3 In the time domain, the first RUR 1542 extends from time t 5 to time t 11 and the second RUR 1544 extends from time t 7 to time t 12

[0176] The first communication device determines that both the first RUR 1542 and the second RUR 1544 indicate some of the first communication resources 1522. Specifically, the first bitmap 1552 indicates resources extending from time t 7 to time t 11 and from frequency f l to frequency f 2 The second bitmap 1554 indicates resources within a sub-part extending from frequency f l to frequency f 2 and from time t 7 to time t 8 Since both UL-CIs 1532 and 1534 indicate a part of the first communication resources, the first communication device 270a refrains from transmitting using the first communication resources 1522.

[0177] Conversely, the second bitmap 1554 does not indicate a sub-part of the second RUR 1544 that includes resources of the second communication resources 1524. Thus, the second communication device 270b does not refrain from transmitting using the second communication resources 1524 and transmits data using these resources.​

[0178] In some such embodiments, it may be apparent that the UL-CI bitmap may not actually reflect resources that are subject to collisions (e.g., sub-parts of the RUR). In the example of FIG. 15, the second bitmap 1554 extends from frequency f l to frequency f 2 and time t 7 to time t 8 and indicates at least some of the resources within a sub-part that extends. However, this sub-part does not include any of the second communication resources 1524 and thus does not actually include resources that collide.

[0179] In some embodiments, other rules for determining whether an allocated communication resource should be used for transmission may be used in addition to or instead of those described above. For example, in some embodiments, different communication devices may be configured to monitor different UL-CIs, which may include different subsets in the case of multiple UL-CIs. In some such embodiments, if a communication device receives at least one UL-CI that, according to its configuration, does not indicate that any of the allocated resources are subject to collisions, it may be determined to be permitted to transmit using the allocated resources.

[0180] In some embodiments, if a communication device does not receive any UL-CI that indicates any of the allocated resources according to its configuration, it may be determined to be permitted to transmit using the allocated resources.

[0181] Accordingly, embodiments of the present technology can provide a communication device for determining whether it is permitted to transmit using the allocated communication resources without restrictions on the uplink grant and the relative transmission timing of one or more UL-CIs. Accordingly, for example, even if the infrastructure device cannot schedule the uplink grant and / or UL-CI such that, for one communication device, the uplink grant is within the time window associated with the UL-CI and, for another communication device, the uplink grant is received outside the time window associated with the UL-CI, a way can be shown in which the collision is favorably resolved for one communication device.

[0182] FIG. 16 shows a flowchart of a process that may be performed by a communication device according to embodiments of the present technology.

[0183] The process of FIG. 16 includes steps S602, S604, S606, S608, S610, and S612, which correspond to the above steps with the same numbers in the process of FIG. 6.

[0184] Similar to the process of FIG. 6, in step S612, if it is determined that there is no first uplink communication resource within the indicated subpart, the process returns to step S604, as in the process of FIG. 6. However, conversely, if it is determined that a part or all of the first uplink communication resource is within the indicated subpart, as indicated by the UL-CI, the process proceeds to step S1614.

[0185] In step S1614, the communication device determines the time (the "first time") when the uplink allocation was received (step S602) and the time (the "second time") when the UL-CI was received (step S608). Based on the first time and the second time, the communication device determines whether it is permitted to perform data transmission using the allocated resources.

[0186] In the example of the process of FIG. 16, this includes determining the range of the time window associated with the UL-CI based on the second time, and determining whether the first time falls within this time window.

[0187] It will be appreciated that the second time may refer to the start of reception of the UL-CI or the end of reception of the UL-CI. Similarly, the first time may refer to the start of reception of the uplink allocation indication or the end of reception of the uplink allocation indication. In some embodiments, the time window associated with the UL-CI may be defined based on both the start and end of reception of the UL-CI. In some embodiments, instead of determining whether the first time falls within the time window, the communication device may determine whether an entire transmission (e.g., DCI) including the uplink grant indication is received within the time window.

[0188] If the first time is within the time window, the process proceeds to step S1616.

[0189] In step S1616, the communication device determines that the UL-CI indicates at least a part of the communication resources allocated in step S602, but nevertheless, the communication device is permitted to transmit using those allocated resources, and the process returns to step S604.

[0190] Note that in some embodiments, additional UL-CIs may be received (as in the process of FIG. 6), and the uplink grant received in step S602 may not be received within the time window associated with a subsequent UL-CI. Thus, in some embodiments, the determination in step S1616 may not be conclusive in the sense that the communication device may still refrain from transmitting using the resources allocated based on a subsequent UL-CI.

[0191] In step S1614, if it is determined that the first time is not within the time window (or, generally, if the test based on the first time and the second time applied in step S1614 is not satisfied), the process proceeds to step S1618.

[0192] In step S1618, it is determined whether a further uplink grant is received that allocates the same resources as those allocated by the instruction (e.g., uplink grant) received in step S602. If received, it is determined whether the test performed in step S1614 is satisfied considering the further uplink grant and the UL-CI received in step S608.

[0193] If a further uplink grant that satisfies the test is received, the process proceeds to step S1616. As a result, the communication device is not prevented from transmitting using the resources allocated by the UL-CI received in step S608.

[0194] If a further uplink grant that satisfies the test is not received, the process proceeds to step S1620. In step S1620, the process ends without the communication device transmitting uplink data using the resources allocated in step S602.

[0195] As described above, and in some embodiments as shown in FIG. 14, in step S1618, instead of determining whether a later uplink grant is received within the time window associated with the UL-CI, the communication device determines whether a later uplink grant is received before the time determined based on the start of the allocated communication resources and, in some embodiments, on a predetermined duration related to the minimum time for canceling or preparing for transmission.

[0196] It will be appreciated that in some embodiments, a further uplink grant may be received that allocates different communication resources that may be used for the transmission of data by the communication device (in accordance with the process of FIG. 16 or in some other manner).

[0197] It will be understood that the scope of the present disclosure is not limited to the process shown in FIG. 16 above. In some embodiments of the present technology, the steps of the process of FIG. 16 may be rearranged and / or one or more steps may be omitted. For example, in some embodiments, step S1618 is omitted, and as a result, if the UL-CI is received and the uplink grant does not meet the test in step S1614, the process proceeds directly to step S1620.

[0198] In some embodiments, the possibility of receiving a later UL-CI is not considered, and thus, following step S1616, the communication device waits until the start time of the allocated resources and then proceeds directly to step S606.

[0199] As described herein, embodiments of the present technology can avoid two or more communication devices responding to the UL-CI in the same way such that either the communication device does not transmit or both communication devices transmit and cause a collision. Embodiments of the present technology provide different behaviors of the communication device, for example, based on the relative time between the reception of the UL-CI and the reception of the uplink grant by that communication device.

[0200] According to embodiments of the present technology, this behavior of the communication device follows a predetermined rule. These rules may be specified in an appropriate specification and / or may be indicated to the communication device by an infrastructure device (such as infrastructure device 272) of the wireless communication network. Similarly, the behavior may further follow a predetermined parameter that is specified in an appropriate specification and / or indicated to the communication device by the infrastructure device or otherwise may be set in the communication device.

[0201] Furthermore, embodiments of the present disclosure provide a method in which an infrastructure device allocates a first uplink resource to a first communication device and then allocates a second uplink resource (including some or all of the first uplink resource) to a second communication device (thus causing a collision), and transmits an indication of the collision received by both communication devices, wherein the first and second communication devices can behave differently when determining whether to transmit using their respective allocated resources.

[0202] Accordingly, embodiments of the present technology can enable an infrastructure device to indicate a collision such that one (and only one) of the affected communication devices determines to transmit using the collided resource. In some embodiments, the infrastructure device selects respective times for transmitting an indication of the collision, an indication of the allocation of the first uplink resource to the first communication device, and an indication of the allocation of the second uplink resource to the second communication device, such that the second communication resource determines that it may ignore the indication of the collision and further determines to transmit data using the allocated resource according to the technology disclosed herein.

[0203] In some embodiments, the infrastructure device transmits a further indication of the collision and / or a further indication of the allocation of the second uplink resource to the second communication device, such that the second communication resource determines that it may ignore the indication of the collision and further determines to transmit data using the allocated resource according to the technology disclosed herein.

[0204] In some embodiments, the allocation of the second uplink resource to the second communication device is based on the quality of service requirements associated with the data transmitted by the second communication device using the second uplink resource.

[0205] Embodiments of the present technology can avoid the need for additional information transmitted within the UL-CI (or transmitted together with the UL-CI). Embodiments of the present technology can resolve collisions even when the physical layer priorities associated with data transmitted using colliding resources are the same.

[0206] Various examples are described herein. It will be understood that the scope of the present disclosure is not limited to specific combinations of features shown in these examples, and aspects of different examples may be combined.

[0207] For example, a determination by a communication device that a resource allocated for transmission of data by the communication device is also allocated for transmission of data by another communication device may be made by the UL-CI bitmap described herein or by any other method such as receiving a different form of indication. In some embodiments, the indication is a broadcast or multicast indication. In some embodiments, the indication does not explicitly indicate which of two overlapping resource allocations to cancel.

[0208] Accordingly, embodiments of the present technology provide a method of operating a communication device in a wireless communication network, the method comprising receiving an uplink grant indication at a first time, the uplink grant indication indicating a first uplink communication resource allocated for transmission of first data by the communication device, receiving an uplink cancellation indication (UL-CI) at a second time, the UL-CI indicating a second uplink communication resource, the second uplink communication resource including at least a portion of the first uplink communication resource, and determining whether to transmit the first data using the first uplink communication resource based on the first time and the second time in response to receiving the uplink grant indication and the uplink cancellation indication.

The operation method has also been described.

The operation method has also been described.

[0213] The corresponding communication device, infrastructure device, and circuits of the communication device and the infrastructure device have also been described.
