Description

AREA

[0001] The present application concerns wireless communication and, in particular, techniques for multiplexing different mobile communication services. DESCRIPTION OF RELATED TECHNOLOGY

[0002] The use of wireless communication systems is increasing rapidly. Furthermore, there are numerous different technologies and standards for wireless communication. Some examples of wireless communication technologies include GSM, UMTS (for example, in conjunction with WCDMA or TD-SCDMA air interfaces), LTE, LTE Advanced (LTE-A), HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), IEEE 802.11 (WLAN or Wi-Fi), IEEE 802.16 (WiMAX), Bluetooth, and others.

[0003] For some wireless communication standards, such as the physical layer design of the 5G air interface, different types of services are proposed. For example, enhanced mobile broadband (eMBB) can provide a high-speed data service with a latency requirement (e.g., 4 ms), while an ultra-reliable low-latency (URLLC) service can provide a highly reliable service with a lower latency requirement (e.g., 0.5 ms) than eMBB. In general, different services using a unified physical layer framework can exhibit very different characteristics in terms of reliability, latency, data rate, and so on.Accommodating such diverse services while maintaining consistent performance, low complexity and low power consumption (e.g., both at the base station and on mobile devices) can be a challenge.

[0005] This patent specification includes references to various embodiments to indicate that the present disclosure is not intended to refer to a specific implementation, but rather to a range of embodiments which, including the attached claims, fall within the spirit of the present disclosure. Particular features, structures, or properties may be combined in any suitable manner consistent with this disclosure.

[0006] Within this disclosure, various entities (which may be referred to differently as “units,” “circuits,” other components, etc.) may be described or claimed to be “configured” to perform one or more tasks or operations. This phrase—[unit] configured to [perform one or more tasks]—is used herein to refer to the structure (i.e., something physical, such as an electronic circuit). More specifically, this phrase is used to indicate that this structure is arranged to perform one or more tasks during operation. A structure may be described as “configured to” perform a task even if the structure is not currently operating.For example, a “clock circuit configured to generate an output clock signal” is intended to cover a circuit that performs this function during operation, even when the circuit in question is not currently in use (e.g., when it is not connected to the power supply). Similarly, a unit described or enumerated as “configured to” perform a task refers to something physical, such as a device, a circuit, a memory that stores program instructions executable to perform the task, and so on. This phrase is not used here to refer to something intangible.

[0007] The term "configured to" does not mean "configurable to." For example, an unprogrammed FPGA would not be considered "configured to" perform a specific function, even though it may be "configurable to" perform that function. After appropriate programming, the FPGA can then be configured to perform that function.

[0008] The statement in the accompanying claims that a structure is "configured to" perform one or more tasks is expressly not intended to refer to 35 USC § 112(f) for that claim element. Accordingly, none of the claims in this application as filed are to be interpreted as having elements of means plus function. If the applicant wishes to rely on § 112(f) during prosecution, he shall specify the claim elements using the construct "means to" [perform a function].

[0009] As used herein, the term "based on" is used to describe one or more factors that influence a determination. This term does not exclude the possibility that additional factors may influence the determination. That is, a determination may be based solely on specified factors, or on the specified factors as well as other, unspecified factors. Consider the sentence "Determine A based on B." This sentence states that B is a factor used to determine A or that influences the determination of A. This sentence does not exclude the possibility that the determination of A may also be based on another factor, such as C. This expression is also intended to cover an embodiment in which A is determined solely based on B. As used herein, the expression "based on" is synonymous with the expression "at least partially based on." DETAILED DESCRIPTION Abbreviations

[0011] The following is a glossary of terms used in this revelation:

[0012] Storage medium – any of the various types of non-volatile memory devices or data storage devices. The term "storage medium" is intended to include installation media, e.g., a CD-ROM, floppy disks, or tape device; computer system memory or random access memory, such as DRAM, DDR-RAM, SRAM, EDO-RAM, Rambus-RAM, etc.; non-volatile memory, such as flash memory; magnetic storage media, e.g., a hard disk or optical data storage device; registers or other similar types of memory elements, etc. The storage medium may include other types of non-volatile memory as well as combinations thereof.Furthermore, the storage medium can be located in a first computer system where the programs are executed, or it can be located in a second, different computer system connected to the first computer system via a network, such as the internet. In the latter case, the second computer system can provide the first computer with program instructions for execution. The term "storage medium" can include two or more storage media, which may be located in different places, for example, in different computer systems connected via a network. Program instructions (e.g., in the form of computer programs) can be stored on the storage medium and executed by one or more processors.

[0013] Carrier medium - a storage medium as described above, as well as a physical transmission medium, such as a bus, a network and / or another physical transmission medium, that transmits signals, such as electrical, electromagnetic or digital signals.

[0014] Computer system – any of several different types of computing or processing systems, including a personal computer system (PC), mainframe system, workstation, network appliance, internet appliance, personal digital assistant (PDA), television system, grid computing system, or any other device or combination of devices. In general, the term "computer system" can be broadly defined to include any device (or combination of devices) with at least one processor that executes instructions from a storage medium.

[0015] User equipment (UE) (or "UE device") – any of the many types of computer system devices that are mobile or portable and perform wireless communication. Examples of UE devices include mobile phones or smartphones (e.g., iPhone™, Android™-based phones), portable gaming devices (e.g., Nintendo DS™, PlayStation Portable™, Gameboy Advance™, iPhone™), laptops, body-worn devices (e.g., smartwatches, smartglasses), PDAs, portable internet devices, music playback devices, data storage devices, or other handheld devices, etc. In general, the term "UE" or "UE device" can be broadly defined to encompass any electronic, computing, and / or telecommunications device (or combination of devices) that can be easily transported by a user and is capable of wireless communication.

[0016] Base station - The term 'base station' encompasses the full breadth of its usual meaning and includes at least one wireless communication station installed in a fixed location and used to communicate as part of a wireless mobile phone system or cellular network system.

[0017] Processing element - refers to various elements or combinations of elements capable of performing a function in a device, such as user equipment or a mobile network device. to perform. Processing elements may include, for example: processors and associated memory, sections or circuits of individual processor cores, entire processor cores, processor arrays, circuits such as an application-specific integrated circuit (ASIC), programmable hardware elements such as a field-programmable gate array (FPGA), and any of the many combinations of the foregoing.

[0018] Channel – a medium used to transmit information from a sender (transmitter) to a receiver. It should be noted that, since the characteristics of the term "channel" can vary according to different wireless protocols, the term "channel" as used herein should be understood as being used in a manner consistent with the standard of the type of device to which the term refers. In some standards, channel widths may be variable (e.g., depending on device capacity, band conditions, etc.). For example, LTE may support scalable channel bandwidths from 1.4 MHz to 20 MHz. In contrast, WLAN channels may be 22 MHz wide, while Bluetooth channels may be 1 MHz wide. Other protocols and standards may include different channel definitions. Furthermore, some standards may define and use multiple types of channels, e.g.,different channels for uplink or downlink and / or different channels for different uses such as data, control information, etc.

[0019] Band - The term 'band' encompasses the full breadth of its usual meaning and includes at least a section of a spectrum (e.g., a radio frequency spectrum) in which channels are used or reserved for the same purpose.

[0020] Automatic – refers to an action or operation (e.g., software executed by the computer system) performed by a computer system or device (e.g., switching logic, programmable hardware elements, ASICs, etc.) without user input that directly defines or executes the action or operation. Thus, the term "automatic" contrasts with an operation performed or defined manually by the user, where the user provides input to directly execute the operation. An automatic procedure may be initiated by user input, but the subsequent actions performed "automatically" are not defined by the user; that is, they are not performed "manually," with the user specifying each action to be carried out.For example, a user who completes an electronic form by selecting each field and providing input that specifies information (e.g., by typing information, selecting checkboxes, choosing a radio button, etc.) is manually filling out the form, even though the computer system needs to update the form in response to the user's actions. The form can be automatically filled out by the computer system, where the computer system (e.g., software running on the computer system) analyzes the form's fields and completes the form entirely without any user input specifying the answers to the fields. As mentioned above, the user can request automatic form completion but is not involved in the actual process of filling out the form (e.g., the user does not manually specify answers for fields; these are filled in automatically).The present patent specification provides various examples of operations that are performed automatically in response to actions taken by the user.

Overview of service multiplexing techniques

[0042] In various implementations, it can be challenging to support data services with differing characteristics within a unified physical layer framework while maintaining performance, low complexity, and low power consumption. For example, it may be necessary to schedule URLLC signaling with very low latency and extremely high reliability requirements when an eMBB transmission is in progress to achieve the target latency (e.g., waiting for the eMBB transmission to finish might take longer than the longest latency allowed for URLLC). Furthermore, different data services may use time windows of varying lengths; for instance, eMBB time windows might use 14 symbols, while URLLC might use mini-time windows of 2, 4, or 7 symbols.

[0043] Therefore, multiplexing techniques are used in various embodiments to share the time and frequency resources of the physical layer between different services. URLLC and eMBB are explained herein for illustrative purposes, but are not intended to limit the scope of this disclosure; the disclosed techniques can be used between any number of different data services.

[0044] In general, a base station can be configured to schedule URLLC transmissions using unused resources so that they do not affect other data transmissions when unused time and / or frequency resources are available during eMBB transmissions. If no unused resources are available, some embodiments may allow URLLC to preempt eMBB transmissions, which can meet URLLC latency requirements but may contaminate eMBB data and degrade the performance of eMBB packets (e.g., by increasing the block error rate (BLER)). Furthermore, UL-eMBB transmissions from nearby UEs can interfere with URLLC transmissions. Therefore, in some embodiments, other UEs are configured to punctuate their UL resources (e.g., by foregoing transmission or transmitting at reduced power) to reduce interference with URLLC communications. Exemplary indicator for FDD systems

[0045] Fig. Figure 5 is a block diagram illustrating the punctuation of eMBB-UL transmissions to avoid interference with URLLC communication. In the illustrated embodiment, the top representation represents a DL control channel, the middle representation represents eMBB-UL transmissions, and the bottom representation represents URLLC transmissions (which can be uplink or downlink). Although the three representations are shown separately, they can correspond to the same set of time-frequency resources (e.g., the URLLC data). 560 using some of the same time and frequency resources as the UL-EMBB data 540 transferred as shown).

[0046] In the illustrated embodiment, the downlink control channel includes downlink control information (DCI) for the eMBB 510, which includes control information for the UL push for the eMBB data 540. For example, the DCI 510 Among other information, it displays resources scheduled for UL transmission. In the illustrated embodiment, the downlink control channel also includes the DCI for URLLC. 520 one, the tax information for the URLLC data 560 included. In the illustrated embodiment, the DCI include 520 an indicator 530 an indicator that displays the resources used by URLLC communication. In various forms, the indicator can... 530 included in a URLLC-DCI or communicated separately.

[0047] In some embodiments, the indicator is UE-specific. In some embodiments, the indicator is group-specific, e.g., in a group-common Physical Downlink Control Channel (GC-PDCCH). In some embodiments, the indicator is common to several UEs. In some embodiments, the indicator is transmitted in a dedicated signaling system.

[0048] A UE transmitting the eMBB data 540 in the illustrated embodiment is configured to transmit it within an area (represented as dotted resources). 550 ) to puncture in order to avoid interference with the URLLC data 560to reduce. In some embodiments, the UE therefore performs full-duplex communication by monitoring the downlink control channel while simultaneously transmitting uplink data. In some embodiments, the different frequency bands of the uplink data and the downlink control channel can avoid interference between the transmitted data and the received control channel. When the UE displays 530 Once detected in the control channel, it can proceed to punctuate its specified transmissions.

[0049] As an example of punctuation, the UE can completely block transmissions using the specified resources in the time and / or frequency dimension. As another example, the UE can reduce the transmission power for the specified resources. The power reduction can be controlled in the time and / or frequency dimension in various embodiments. For example, in some embodiments, the UE can reduce the power during URLLC data communication across all frequencies, while in other embodiments, the UE can reduce the power only for the specified time and frequencies. In some embodiments, multiple UEs monitor the indicator in the area. 530 and punctuate their transmissions as needed. In various embodiments, the disclosed techniques can enhance the wireless performance for a UE that transmits URLLC data. 560transmits or receives, improving by reducing interference from one or more other UEs.

[0050] Fig. Figure 6A is a diagram illustrating exemplary adjacent cells according to some embodiments. In some embodiments, UEs in other cells can also determine their transfers based on the indicator. 530 puncture. For example, if the base station 102A a URLLC communication with the UE 106A carries out the UE 106B in the neighboring cell their transmissions based on a specification from the base station 102APuncture. In some embodiments, cell-specific information can be encrypted to avoid interference between puncture indicators from different base stations. Therefore, in some embodiments, the UEs can monitor puncture indicators from several different base stations simultaneously while performing uplink transmissions.

[0051] Fig. Figure 6B is a diagram illustrating exemplary beam-based communication according to some embodiments. In embodiments that use beamforming, devices on one beam can cause very limited interference with devices on other beams. For example, in the illustrated embodiment, the UL transmission from the UE may 106B communication with the UE 106A not cause significant disturbance. Therefore, the base station 102In some embodiments, it is configured to transmit a puncture indication only along one or more beams that are actually used by a URLLC device. Exemplary TDD techniques

[0052] Fig. Figure 7 is a diagram illustrating an example of TDD-eMBB-UL transmissions based on URLLC communication. In some implementations, the TDD (Time-Dimension Duplexing) communication switches between uplink and downlink transmissions, e.g., using the same set of frequency resources.

[0053] As shown, for example, the downlink DCI for an eMBB 710 is transmitted using the same frequency resources as (but at a different time than) the UL-eMBB 740 data it controls. Similarly, the downlink DCI for URLLC 720 using the same frequency resources as the URLLC data 760transferred. It should be noted that the eMBB-UE the DCI 720 may not be able to capture, e.g. because the eMBB-UE is in a UL transmit mode and cannot perform DL receive simultaneously in TDD implementations.

[0054] Therefore, in some versions, the base station is configured to include a puncture indicator. 730 to transmit in a control band (which may be a narrow, dedicated frequency band) that is separate from the band used for TDD communication, as shown. In these embodiments, the eMBB-UEs can monitor the control band for the indicator while performing TDD-UL transmissions and the puncture resources used by URLLC (e.g., punctured resources). 750 , in the illustrated example) monitor accordingly.

[0058] At 830 The UE is recorded 106 In the illustrated embodiment, a puncture indicator is present in the control channel and punctures its transmission at 840. The puncture can include, for example, the muting time and / or frequency components of one or more planned transmissions or a transmission at reduced power.

[0059] At 850 sets the UE 106 In the illustrated embodiment, the transmission of the planned UL-eMBB data continues. The UE can, for example, resend hidden transmissions at a later time or wait to determine if the base station 102 received reduced-power transmissions before sending again.
