Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as Long Term Evolution (LTE) or fifth generation (5G) radio access technology or new radio (NR) access technology, or other communications systems. For example, certain example embodiments may relate to apparatuses, systems, and/or methods for common frequency resource, control resource set configurations, and common frequency resource switching.
Examples of mobile or wireless telecommunication systems may include the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Long Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE-Advanced (LTE-A), MulteFire, LTE-A Pro, and/or fifth generation (5G) radio access technology or new radio (NR) access technology. Fifth generation (5G) wireless systems refer to the next generation (NG) of radio systems and network architecture. 5G network technology is mostly based on new radio (NR) technology, but the 5G (or NG) network can also build on E-UTRAN radio. It is estimated that NR will provide bitrates on the order of 10-20 Gbit/s or higher, and will support at least enhanced mobile broadband (eMBB) and ultra-reliable low-latency-communication (URLLC) as well as massive machine type communication (mMTC). NR is expected to deliver extreme broadband and ultra-robust, low latency connectivity and massive networking to support the Internet of Things (IoT). With IoT and machine-to-machine (M2M) communication becoming more widespread, there will be a growing need for networks that meet the needs of lower power, low data rate, and long battery life. It is noted that, in 5G, the nodes that can provide radio access functionality to a user equipment (i.e., similar to Node B in UTRAN or eNB in LTE) are named gNB when built on NR technology and named NG-eNB when built on E-UTRAN radio.

For proper understanding of example embodiments, reference should be made to the accompanying drawings, wherein:
It will be readily understood that the components of certain example embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatuses, and computer program products for common frequency resource and control resource set configurations, and common frequency resource switching.
The features, structures, or characteristics of example embodiments described throughout this specification may be combined in any suitable manner in one or more example embodiments. For example, the usage of the phrases “certain embodiments,” “an example embodiment,” “some embodiments,” or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, appearances of the phrases “in certain embodiments,” “an example embodiment,” “in some embodiments,” “in other embodiments,” or other similar language, throughout this specification do not necessarily refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments.
3rd Generation Partnership Project (3GPP) defines common frequency resource (CFR) for radio resource control (RRC) user equipment in idle and inactive states, and a corresponding control resource set (CORESET) configuration for RRC_IDLE/INACTIVE UEs to receive broadcast services. For RRC_IDLE/INACTIVE UEs, CFR(s) for group-common physical downlink control channel/physical downlink shared channel (PDCCH/PDSCH) have been defined/configured. Here CFRs may imply a common set of frequency resources/physical resource blocks where the multicast or broadcast control and data channel traffic is scheduled by the network. In this case, the UE may assume that an initial bandwidth part (BWP) is the default CFR for the group-common PDCCH/PDSCH if a specific CFR is not configured. Initial BWP may be the set of frequency resources used by the UE for initial access before a radio resource control connection is established with the network. Further, the initial BWP may be monitored by idle/inactive mode UEs for receiving various information—such as paging, multicast or broadcast, from the network. In other cases, for RRC_IDLE/INACTIVE UEs, a CORESET—dedicated to multicast/broadcast, may be configured within the CFR for group-common PDCCH/PDSCH. Here, CORESET #0 may be used by default if the CFR for group-common PDCCH/PDSCH is the initial BWP and the CORESET is not configured.
Regarding the CFR(s) configuration for RRC_IDLE/INACTIVE UEs, for broadcast reception, there may be cases of a configured/defined specific CFR for the group-common PDCCH/PDSCH. For instance, in a Case E (e.g.,
In the case where the initial BWP fully includes the CFR in the frequency domain, several sub-cases may be considered. For instance, in a Case B (e.g.,
3GPP also describes cases where the initial BWP may be the same size as the CFR in the frequency domain. For instance, in a Case A (e.g.,
As described in 3GPP TS38.306, the UE may have certain capabilities with parameter multipleCORESET, which may indicate whether the UE supports a configuration of more than one or up to two PDCCH CORESETs per BWP in addition to the CORESET with CORESET-ID 0 in the BWP. If this is not supported, the UE may support one PDCCH CORESET per BWP in addition to the CORESET with CORESET-ID 0 in the BWP. As such, this may suggest that the UEs may support two CORESETs (CORESET #0+Additional CORESET, where the Additional CORESET is configured by commonControlResourceSet) per BWP and the support of three CORESETs (CORESET #0+Additional-2-CORESETs) may be an optional UE capability. In some cases, a maximum five CORESETS (CORESET #0+Additional-4-CORESETs) may be an optional capability for the UEs.
Case B in the example of
For Case D, the CFR may be smaller than the initial BWP, and CORESET #0 may be confined within the SIB1 configured initial BWP. This case may be seen as a special case of Case C, where with inclusion of additional CFR frequency-range configuration is smaller than the initial BWP. If the configured CFR frequency-range configuration is the same as the initial BWP, then it may be identical to the default Case C. Furthermore, considering if the payload size of MCCH/MTCH is smaller than paging/OSI/RAR, and also a more frequent need to be monitored, different SS monitoring periodicity may be configured for MBS services. For Case E, a separate MBS BWP may be configured. Such configuration may be beneficial when large data payload with MBS services need to be transmitted with a larger bandwidth than the initial BWP can handle.
In certain examples, the CFR CORESET design for RRC_IDLE/INACTIVE UEs to receive MBS services may depend on the CFR that is defined. As such, certain example embodiments provide a method that addresses the open CORESET issues. For instance, certain example embodiments provide a way for the CORESET for MBS services for RRC_IDLE/INACTIVE UEs to be configured to support different CFR cases (e.g., Case A, C, D, and/or E). Certain example embodiments also provide a way to handle switching between a BWP and CFR(s). Moreover, certain example embodiments may consider the CFR configuration for MCCH and MTCH, which may be configured differently as well as it may be the same CFR for both MCCH and MTCH.
Certain example embodiments may be based on different CFR configuration cases (e.g., Case A/C/D/E), and may provide how the CORESET for MBS services for RRC_IDLE/INACTIVE UEs may be configured. For instance, as illustrated in the example of
With regard to Case C in the example of
According to certain example embodiments, the CORESET may be mapped with a certain broadcast service that can be made in terms of mbsSearchSpace configuration in the CORESET that may be configured via MBS SIB or MCCH. Further, a searchSpaceId (that is mapped to one of the mbsSearchSpace(s)) may be included in one or more group radio network temporary identifier(s) (G-RNTI(s)) configuration, or a different searchSpaceId may be associated with different G-RNTI configuration. Thus, different MBS services may share a search space, or have separate search spaces.
In certain example embodiments, for CORESET #0 and CORESET via commonControlResourceSet, a new search-space (SS) monitoring occasion (MO) configuration(s) may be provided to the RRC_IDLE/INACTIVE UEs receiving MBS services (e.g., via MBS SIB or MCCH). In doing so, the CORESET #0 and CORESET via commonControlResourceSet may include different SSs for different UEs. In addition, it may be possible to avoid legacy UEs and UEs that are not interested in MBS services to frequently monitor CORESET #0 PDCCH, and save power. In some example embodiments, one or more new SS MO may be configured corresponding to different MBS services. That is, according to certain example embodiments, there may not need to be just one SS MO configured for multiple MBS services.
With regard to Case D in the example of
According to further example embodiments, with regard to Case D in the example of
According to certain example embodiments, with regard to Case E in the example of
In certain example embodiments, by assuming and considering if the multiple CFRs and multiple MCCHs are supported, the gNB may also be allowed to configure separated/different CFR for multiple MCCH(s) and MTCH(s), as illustrated in the example of
In certain example embodiments, with regard to Case E in the example of
For instance, according to certain example embodiments, under the legacy approach, if the UE is configured with the CORESET via commonControlResourceSet for broadcast services, the UE may monitor broadcast services via the CORESET configured via commonControlResourceSet as well as CORESET #0. Otherwise, if the CORESET via commonControlResourceSet is not configured and the UE is configured with broadcast service reception, the UE may monitor the CORESET #0 for broadcast services as a default.
In certain example embodiments, if the UE is configured with the CORESET via commonControlResourceSet for certain broadcast service(s), the UE may monitor that specific broadcast service(s) via the CORESET configured via commonControlResourceSet. In addition, the UE may monitor other broadcast services via CORESET #0. Furthermore, in case of multiple broadcast services, the UE may be configured to monitor CORESET via commonControlResourceSet for some services, while monitoring CORESET #0 for other services.
According to certain example embodiments, the broadcast service with the CORESET configured via commonControlResourceSet may have a different monitoring occasion/reception cycle from the broadcast services that are monitored at CORSET #0 (i.e., the UE may frequently monitor a certain broadcast service with CORESET configured via commonControlResourceSet than the broadcast services monitored at CORESET #0). With such a configuration, the NR broadcast services may be configured and monitored by the UE both in the CORESET #0 and the CORESET configured via commonControlResourceSet. According to certain example embodiments, to have a mapping between broadcast service to one of the CORESETs, several methods, such as a new parameter in MBS service configuration or G-RNTI configuration may be individually used.
In other example embodiments, where MBS service to CORESET mapping is not used, frequent monitoring of a certain broadcast service via CORESET #0 may jeopardize the performance of legacy UEs from a power saving perspective. Instead, certain example embodiments may 1o provide a new SS configuration to the MBS UE via MBS SIB or MCCH. This SS may be located at CORESET #0 so that the legacy UEs and the UEs that are not interested in MBS services are not required to monitor CORESET #0 PDCCH with an increased frequency. Similarly, for CORESET configured via commonControlResourceSet, a new SS (i.e., mbsSearchSpace) may be configured via MBS SIB/MCCH specifically for MBS that enables a similar behavior. For instance, different monitoring occasion may be configured for the UEs receiving MBS service(s) than conventional monitoring occasions that are followed by the legacy UEs that also monitor the legacy commonControlResourceSet. According to certain example embodiments, mapping of the new SS with a certain broadcast service may be made by mbsSearchSpace configuration in the CORESET via MBS SIB or MCCH, where a searchSpaceId is linked with one or more G-RNTI(s) configuration, or different searchSpaceId is associated with different G-RNTI configuration. Otherwise, if the CORESET via commonControlResourceSet is not configured, the UE may monitor the CORESET #0 for broadcast services by default.
According to certain example embodiments, if the legacy CORESET via commonControlResourceSet is not configured for the MBS UE, configurations by the gNB may still stick to the legacy limitation on support of two CORESETs per BWP (i.e., CORESET #0 and CFR_CORESET configured via a new CORESET configuration, such as, for example, commonControlResourceSet_CFR in the initial BWP).
Furthermore, in certain example embodiments, if the UE is configured with CFR_CORESET for a certain broadcast service, the UE may monitor that broadcast service via the CFR_CORESET configured via commonControlResourceSet_CFR. In addition, the UE may monitor other broadcast services via CORESET #0. In other example embodiments, the broadcast service with the CFR_CORESET may have a different monitoring/reception cycle from the broadcast service with CORESET #0. For example, the UE may need to more frequently monitor a certain broadcast service with CFR_CORESET than the broadcast service with CORESET #0. Therefore, in certain example embodiments, NR broadcast services may be configured and monitored by the UE both in the CORESET #0 as well as CFR_CORESET depending on the broadcast service types, as illustrated in the example of
According to certain example embodiments, the CORESET may be an MBS service-specific configuration for the UE to monitor. In addition, for the configured CFR CORESET(s), depending on UE capability, the UE may perform a narrow CFR bandwidth operation at a certain time stamp (e.g., as illustrated in the example of

The apparatus may also include means for monitoring the at least one broadcast service on the communication resource based on the configuration. According to certain example embodiments, the communication resource may be a subset of an initial bandwidth part, or the communication resource may include an initial bandwidth part as a subset of the communication resource.
Other example embodiments may be directed to an apparatus that includes means for configuring a user equipment to monitor at least one broadcast service on a communication resource. According to other example embodiments, the communication resource may be a subset of an initial bandwidth part, or the communication resource may include an initial bandwidth part as a subset of the communication resource.
Certain example embodiments described herein provide several technical improvements, enhancements, and/or advantages. In some example embodiments, it may be possible to configure the CORESET for MBS services for RRC_IDLE/INACTIVE UEs. According to other example embodiments, it may be possible to provide CFR configuration for MCCH and MTCH, and configure separate/different CFRs for multiple MCCH(s) and MTCH(s). In further example embodiments, it may be possible for UEs to achieve power saving by switching from the initial BWP to the bandwidth of narrow CFR_CORESET where the operation with configured narrow CFR may occur at certain time stamps.
In some example embodiments, an apparatus may include or be associated with at least one software application, module, unit or entity configured as arithmetic operation(s), or as a program or portions of programs (including an added or updated software routine), which may be executed by at least one operation processor or controller. Programs, also called program products or computer programs, including software routines, applets and macros, may be stored in any apparatus-readable data storage medium and may include program instructions to perform particular tasks. A computer program product may include one or more computer-executable components which, when the program is run, are configured to carry out some example embodiments. The one or more computer-executable components may be at least one software code or portions of code. Modifications and configurations required for implementing the functionality of an example embodiment may be performed as routine(s), which may be implemented as added or updated software routine(s). In one example, software routine(s) may be downloaded into the apparatus.
As an example, software or a computer program code or portions of it may be in a source code form, object code form, or in some intermediate form, and it may be stored in some sort of carrier, distribution medium, or computer readable medium, which may be any entity or device capable of carrying the program. Such carriers may include a record medium, computer memory, read-only memory, photoelectrical and/or electrical carrier signal, telecommunications signal, and software distribution package, for example. Depending on the processing power needed, the computer program may be executed in a single electronic digital computer or it may be distributed amongst a number of computers. The computer readable medium or computer readable storage medium may be a non-transitory medium.
In other example embodiments, the functionality may be performed by hardware or circuitry included in an apparatus (e.g., apparatus 10 or apparatus 20), for example through the use of an application specific integrated circuit (ASIC), a programmable gate array (PGA), a field programmable gate array (FPGA), or any other combination of hardware and software. In yet another example embodiment, the functionality may be implemented as a signal, a non-tangible means that can be carried by an electromagnetic signal downloaded from the Internet or other network.
According to certain example embodiments, an apparatus, such as a node, device, or a corresponding component, may be configured as circuitry, a computer or a microprocessor, such as single-chip computer element, or as a chipset, including at least a memory for providing storage capacity used for arithmetic operation and an operation processor for executing the arithmetic operation.
