Description

Technical Field

[0001] This invention generally relates to mobile communications, and more specifically, to bandwidth portion (BWP) configurations associated with devices and network nodes in mobile communications. Background Technology

[0002] Unless otherwise stated, the methods described in this section are not considered prior art in the claims, nor are they considered prior art by virtue of their inclusion in this section.

[0003] Wireless communication systems can be widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems can use multiple access technologies that enable communication with multiple users by sharing available system resources. Examples of these multiple access technologies can include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0004] In traditional communication technologies, Broadband Resource Control (BWP) can be used to adjust bandwidth to match service demands, thereby saving energy for devices. However, when BWP changes occur (e.g., network nodes add or modify primary and / or secondary cells), it may be necessary to configure complex BWP settings for devices via Radio Resource Control (RRC) signaling. Complex BWP configurations may contain much of the same information for different BWPs. Therefore, this can result in heavy RRC signaling and long BWP change delays.

[0005] Accordingly, reducing the heavy RRC signaling in BWP configuration in wireless communication environments has become an important issue for newly developed wireless communication networks. Therefore, appropriate solutions are needed to simplify BWP configuration and reduce heavy RRC signaling. Summary of the Invention

However, it should be understood that the inventive embodiments and implementations are merely illustrative of the claimed subject matter, which can be implemented in various forms. Moreover, the invention can be implemented in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided to make the specification of this invention comprehensive and complete, and to fully convey the scope of the invention to those skilled in the art. In the following description, details of known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0018] Overview

[0019] This invention relates to various techniques, methods, schemes, and / or solutions for BWP configuration related to user equipment (UE) and network equipment in mobile communications. According to this invention, multiple possible solutions can be implemented individually or in combination. That is, although these possible solutions may be described individually below, two or more of these possible solutions may be implemented in a combination or other combination manner.

[0020] Figure 1This is an example scenario 100 according to an embodiment of the present invention. Scenario 100 involves UE 110 wirelessly communicating with network 120 (e.g., a wireless network including NTN and TN) via terrestrial network (TN) node 125 (e.g., evolved Node B (eNB), next-generation Node B (gNB), or transmit / receive point (TRP)) and / or non-terrestrial network (NTN) node 128 (e.g., satellite). For example, terrestrial network node 125 and / or non-terrestrial network node 128 may form a non-terrestrial network serving cell to wirelessly communicate with UE 110. In some embodiments, UE 110 may be an Internet of Things (IoT) device, such as an NB-IoT UE or an enhanced machine-type communication (eMTC) UE (e.g., a bandwidth-reduced low complexity (BL) UE or a coverage-enhanced (CE) UE). In such a communication environment, as described below, UE 110, network 120, terrestrial network node 125, and non-terrestrial network node 128 may implement various schemes related to improvements in the BWP configuration process according to the present invention. It is worth noting that although various proposed solutions may be described individually or separately below, in practice, some or all of the proposed solutions may be used in combination or implemented. Of course, each proposed solution may be used or implemented individually or separately.

[0021] According to one embodiment of the present invention, a device (e.g., UE 110) can receive configuration (e.g., Physical Downlink Control Channel (PDCCH) configuration) from a network (e.g., terrestrial network node 125 or non-terrestrial network node 128) via RRC signaling (e.g., UE-specific RRC signaling for adding or modifying a primary or secondary cell). The device can then receive or transmit physical channels or signals from the network node according to the configuration.

[0022] Specifically, when a network node adds or modifies a primary cell and / or secondary cell, the device can receive configuration (or information) from the network node via dedicated RRC signaling to obtain serving cell information. The configuration may include a list of carriers within the serving cell (e.g., carrier identifier (ID) for each carrier in the serving cell, frequency position of each carrier in the serving cell, and bandwidth size of each carrier in the serving cell). The configuration may also include the parameter set (numerology) of the serving cell. The device can determine, based on the configuration, to apply the same parameter set to all carriers and BWPs within the serving cell. The configuration may also include a list of BWPs in the serving cell. The configuration may also include BWPIDs for different types of BWPs, such as initial downlink (DL) or uplink (UL) BWPs, and network energy BWPs. The device can apply BWP configurations with the same BWP ID to the aforementioned BWP types. The configuration may also include physical channel or signal configurations. The device can determine, based on the configuration, that some physical channel or signal configurations are common to all BWPs within the serving cell. The configuration may also include the configuration of measurement resources and reports for radio link measurement and beam management. The configuration may also include the configuration of rate matching modes. The device can determine whether the rate matching mode configuration is carrier-specific based on the configuration, and apply the corresponding rate matching mode to the corresponding carrier.

[0023] According to one embodiment of the present invention, the configuration from the network node may include the physical channel or signal configuration of multiple BWPs within the serving cell (e.g., primary cell or secondary cell).

[0024] According to one embodiment of the present invention, the physical channel or signal configuration may include at least one BWP-specific configuration or BWP-related configuration (also referred to as the first configuration in this invention). Each BWP may correspond to one BWP-specific configuration. That is, each BWP-specific configuration is not a common configuration for all BWPs in the serving cell. The BWP-specific configuration may be associated with a BWPID. In addition, the BWP-specific configuration may include a control resource set (CORESET) configuration (e.g., time and frequency resources for DL ​​control channel monitoring), a search space configuration (e.g., the downlink control information (DCI) format for monitoring, the aggregation level and number of candidates for monitoring, the period of the search space, and the timing of the search space monitoring over a period of time), the maximum number of multiple-input multiple-output (MIMO) layers, at least one of the channel state information-reference signal (CSI-RS) port number and the CSI-RS period. The BWP-specific configuration can be changed by an active BWP switch. That is, the above parameters in the BWP-specific configuration can be adjusted by changes in the BWP.

[0025] According to one embodiment of the present invention, the physical channel or signal configuration may further include a non-BWP-specific configuration (also referred to as a second configuration in this invention) applied to multiple BWPs. That is, the non-BWP-specific configuration is a common configuration for multiple BWPs or all BWPs in the serving cell. The non-BWP-specific configuration may not be changed during BWP handover. Therefore, when a BWP change occurs, the non-BWP-specific configuration may not need to be transmitted via RRC signaling to reduce the delay of the BWP change. For the PDCCH configuration, the non-BWP-specific configuration may include at least one of the following: a timeslot format indicator, a Transmit Power Control-Physical Uplink Shared Channel (TPC-PUSCH), a TPC-Physical Uplink Control Channel (TPC-PUCCH), and a TPC-Sound Reference Signal (TPC-SRS).

[0026] According to one embodiment of the present invention, the configuration from the network node may further include a general configuration (also referred to as a third configuration in this invention). The general configuration may include at least one of carrier information (e.g., information on one or more carriers), a parameter set, a timing advance group (TAG) identifier, etc.

[0027] According to one embodiment of the present invention, the configuration from the network node may further include BWP configuration. BWP configuration may include BWPID information and radio resource cluster configuration. Radio resource cluster configuration may include at least one of a list of radio resource clusters, an ID of each radio resource cluster, a frequency location of each radio resource cluster, a bandwidth size of each radio resource cluster, and a time-division duplex (TDD) configuration for each radio resource cluster. A radio resource cluster may be a contiguous radio resource in the intra-carrier frequency domain. The number of supported radio resource clusters may be determined (or reported) based on the device's UE capabilities. The device may determine the frequency resources of at least one BWP based on the radio resource cluster configuration. The device may determine the duplex mode of at least one BWP based on the TDD configuration.

[0028] In a first proposed scheme for frequency resource configuration of a radio resource cluster, if the maximum bandwidth equals the total bandwidth of all carriers within the serving cell, the radio resource cluster configuration may include frequency location and bandwidth size to configure the frequency resources of the radio resource cluster. In a second proposed scheme for frequency resource configuration of a radio resource cluster, if the maximum bandwidth equals the total bandwidth of each carrier, the radio resource cluster configuration may include the carrier ID, frequency location, and bandwidth size of the carrier in which the radio resource cluster resides to configure the frequency resources of the radio resource cluster. In the first proposed scheme, the bit width of the frequency location of the radio resource cluster may be greater than the bit width of the frequency location of the radio resource cluster in the second proposed scheme. According to an embodiment of the present invention, a Resource Indicator Value (RIV) may be used to determine the frequency location and bandwidth size of the radio resource cluster. The RIV may indicate the starting resource block (RB) and the number of RBs. The granularity of frequency resource allocation may include one RB, one subband, or more RBs. Subband-based configuration may have less signaling, but the remainder when the number of RBs in the carrier is divided by the number of RBs in the subband may not be zero.

[0029] According to a first proposed embodiment of the present invention, the PDCCH configuration may include a general configuration (which may be referred to as the third configuration in this invention), a physical channel or signaling configuration, and a BWP configuration. The general configuration can be applied to all PDCCHs in the serving cell. The physical channel or signaling configuration may include the CORESET configuration of BWP 1 (e.g., a CORESET list, CORESET ID, non-BWP-specific configuration, and BWP-specific configuration of BWP 1) and the search space configuration of BWP 1 (e.g., a search space list, search space ID, CORESET ID, non-BWP-specific configuration, and BWP-specific configuration of BWP 1). Furthermore, the physical channel or signaling configuration may also include the CORESET configuration of BWP 2 (e.g., a CORESET list, CORESET ID, non-BWP-specific configuration, and BWP-specific configuration of BWP 2) and the search space configuration of BWP 2 (e.g., a search space list, search space ID, CORESET ID, non-BWP-specific configuration, and BWP-specific configuration of BWP 2). BWP configuration may include BWP ID (e.g., 1) and BWP general information for BWP 1, and BWP ID (e.g., 2) and BWP general information for BWP 2.

[0030] According to a second proposed embodiment of the present invention, the PDCCH configuration may include a general configuration (which may be referred to as the third configuration in this invention), a physical channel or signaling configuration, and a BWP configuration. The general configuration can be applied to all PDCCHs in the serving cell. The physical channel or signaling configuration may include CORESET configuration (e.g., a CORESET list, CORESET ID, and non-BWP-specific configuration) and search space information (e.g., a search space list, search space ID, and non-BWP-specific configuration). The BWP configuration may include a BWP ID (e.g., 1) and BWP general information for BWP 1, and BWP general information for BWP ID (e.g., 2) and BWP 2. Furthermore, the BWP configuration may also include a CORESET configuration for BWP 1 (e.g., a CORESET list, CORESET ID, and BWP-specific configuration for BWP 1) and a search space configuration for BWP 1 (e.g., a search space list, search space ID, CORESET ID, and BWP-specific configuration for BWP 1). In addition, BWP configuration may also include BWP 2’s CORESET configuration (e.g., CORESET list, CORESET ID, and BWP 2’s BWP-specific configuration) and BWP 2’s search space configuration (e.g., search space list, search space ID, CORESET ID, and BWP 2’s BWP-specific configuration).

[0031] According to the third proposed embodiment of the present invention, the PDCCH configuration may include a general configuration (referred to as the third configuration in this invention), physical channel or signaling configuration, and BWP configuration. The general configuration can be applied to all PDCCHs in the serving cell. The physical channel or signaling configuration may include CORESET configurations (e.g., a CORESET list, a CORESET ID, non-BWP-specific configurations, and BWP-specific configurations). The BWP-specific configuration of the CORESET configuration may be associated with the BWP-CORESET list. That is, the BWP-specific configuration may be associated with the BWPID, and the BWPID may be associated with the CORESET ID. The physical channel or signaling configuration may also include search space information (e.g., a search space list, a search space ID, and non-BWP-specific configurations). The BWP-specific configuration of the search space configuration may be associated with the BWP-SS (search space) list. That is, the BWP-specific configuration may be associated with the BWP ID, and the BWPID may be associated with the search space (e.g., BWP 1 has a period of 1 time slot, and BWP 2 has a period of 10 time slots). BWP configuration may include BWP general information such as BWPID (e.g., 1) and BWP 1, as well as BWP general information such as BWPID (e.g., 2) and BWP 2.

[0032] According to one embodiment of the present invention, to ensure energy efficiency of the device, a configuration can be used to guarantee PDCCH monitoring on a single carrier. In one example, the configuration can indicate a list of radio resource clusters within the carrier. In another example, the configuration can indicate a carrier ID and a bitmap of frequency resources to identify the CORESET frequency location. Resource granularity can include a specific granularity of RB, subband, or CORESET, such as a resource element group (REG).

[0065] Additional notes

[0066] The subject matter described in this invention sometimes illustrates different components included within or connected to other components. However, it should be understood that these depicted architectures are merely examples, and many other architectures implementing the same functionality can actually be implemented. Conceptually, any arrangement of components implementing the same function is effectively “associated” to enable the desired functionality. Therefore, regardless of architecture or intermediate components, any two components combined in this invention to achieve a specific function can be considered “associated” with each other to enable the desired functionality. Similarly, any two such associated components can also be considered “operationally connected” or “operationally coupled” to each other to achieve the desired functionality, and any two components that can be suchly associated can also be considered “operationally coupled” to each other to achieve the desired functionality. Specific examples of operationally coupled components include, but are not limited to, physically mating and / or physically interacting components and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.

[0067] Furthermore, regarding any plural and / or singular terms used substantially in this invention, those skilled in the art can convert them from plural to singular and / or from singular to plural as appropriate for the content and / or application. For clarity, various singular / plural substitutions may be explicitly stated in this invention.

[0068] Furthermore, those skilled in the art will understand that, generally, the terms used in this invention, and especially in the appended claims (e.g., the body of the appended claims), are generally meant as “open-ended” terms. For example, the term “comprising” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “at least having,” the term “comprising” should be interpreted as “including but not limited to,” and so on. Those skilled in the art will also understand that if a specific number of claims is intentionally listed, this intention will be explicitly listed in the claims, and the absence of such a listing will not indicate this intention. For example, to aid understanding, the appended claims may include the use of the introductory phrases “at least one” and “one or more.” However, the use of such phrases should not be construed as implying that the introduction of the indefinite article “a” or “an” limits any particular claim that includes such an introductory claim to only one embodiment of such a listing, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an,” for example, “a and / or one” should be interpreted as meaning “at least one” or “one or more,” the same applies to the use of definite articles used to introduce claims. Furthermore, even when a specific number of the introduced claims are explicitly listed, those skilled in the art will recognize that such a listing should be interpreted as meaning at least the number listed. For example, in the absence of other modifiers, the basic listing of "two listings" means at least two listings or two or more listings. Additionally, when using conventions such as "at least one of A, B, and C," it generally means, in the sense that those skilled in the art will understand, that a system having at least one of A, B, and C will include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B together, having A and C together, having B and C together, and / or having A, B, and C together. When using conventions such as "at least one of A, B, or C," it generally means, in the sense that those skilled in the art will understand, that a system having at least one of A, B, or C will include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B together, having A and C together, having B and C together, and / or having A, B, and C together. Those skilled in the art will also understand that any transitional words and / or phrases in the specification, claims, or drawings that actually indicate two or more options should be understood to include the possibility of including one, any, or both of these items. For example, the phrase "A or B" will be understood to include the possibility of including "A" or "B" or "A and B".

[0069] As can be seen from the foregoing, it is understood that various embodiments of the present invention have been described for illustrative purposes, and various modifications can be made without departing from the scope and spirit of the invention. Therefore, the various embodiments disclosed in this invention are not intended to be limiting, and the true scope and spirit are determined by the appended claims.
