Technical Field

Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for accommodating Physical Downlink Control Channel (PDCCH) repetition in the presence of Search Space (SS) set handoffs.

Background

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access techniques 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, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard published by the third generation partnership project (3 GPP).

A wireless network may include a plurality of Base Stations (BSs) that may support communication for a plurality of User Equipments (UEs). The UE may communicate with the BS via the downlink and uplink. "downlink" (or forward link) refers to the communication link from the BS to the UE, and "uplink" (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a node B, gNB, an Access Point (AP), a radio head, a transmission-reception point (TRP), a New Radio (NR) BS, a 5G node B, and so on.

The above multiple access techniques have been employed in various telecommunications standards to provide a common protocol that enables different user devices to communicate at the urban, national, regional, and even global levels. NR (also referred to as 5G) is a set of enhancements to the LTE mobile standard published by 3 GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the Downlink (DL) (CP-OFDM), using CP-OFDM and/or SC-FDM (e.g., also known as discrete fourier transform spread OFDM (DFT-s-OFDM)) on the Uplink (UL) with other open standards, and supporting beamforming, multiple Input Multiple Output (MIMO) antenna technology, and carrier aggregation. With the increasing demand for mobile broadband access, further improvements in LTE, NR and other radio access technologies remain useful

Detailed Description

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method practiced using any number of the aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such an apparatus or method that is practiced using other structure, functionality, or structure and functionality that is additional or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

Several aspects of the telecommunications system will now be presented with reference to various apparatus and techniques. These devices and techniques will be described in the following detailed description and illustrated in the figures by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

It should be noted that although aspects are described herein using terms commonly associated with 5G or NR Radio Access Technologies (RATs), aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and/or RATs after 5G (e.g., 6G).

Fig. 1 is a schematic diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and/or an LTE network, etc. Wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110 d) and other network entities. A Base Station (BS) is an entity that communicates with User Equipment (UE) and may also be referred to as an NR BS, node B, gNB, 5G Node B (NB), access point, transmission-reception point (TRP), and so forth. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to a coverage area of a BS and/or a BS subsystem serving the coverage area, depending on the context in which the term is used.

The BS may provide communication coverage for macro cells, pico cells, femto cells, and/or other types of cells. A macrocell can cover a relatively large geographic area (e.g., a few kilometers in radius) and can allow unrestricted access by UEs with service subscription. Pico cells may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow limited access for UEs having an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). The BS for the macrocell may be referred to as a BS. The BS for the pico cell may be referred to as a pico BS. The BS for the femto cell may be referred to as a femto BS or a home BS. In the example shown in fig. 1, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102 c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "node B", "5G NB" and "cell" are used interchangeably herein.

In some aspects, the cells may not necessarily be stationary, and the geographic area of the cells may move according to the location of the mobile BS. In some aspects, BSs may be interconnected to each other and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as direct physical connections, or virtual networks, using any suitable transport network.

The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or UE) and send the data transmissions to a downstream station (e.g., a UE or BS). The relay station may also be a UE that may relay transmissions of other UEs. In the example shown in fig. 1, relay BS 110d may communicate with macro BS 110a and UE 120d in order to facilitate communication between BS 110a and UE 120 d. The relay BS may also be referred to as a relay station, a relay base station, a relay, and so on.

The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BS, pico BS, femto BS, relay BS, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless communication network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

The network controller 130 may be coupled to a set of BSs and provide coordination and control for the BSs. The network controller 130 may communicate with the BS via a backhaul. BSs may also communicate with each other directly or indirectly through wireless or wired backhaul.

UEs 120 (e.g., 120a, 120b, 120 c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be called an access terminal, mobile station, subscriber unit, station, etc. The UE may be a cellular telephone (e.g., a smart phone), a Personal Digital Assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or apparatus, a biometric sensor/device, a wearable device (smart watch, smart clothing, smart glasses, smart bracelet, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., music or video device, satellite radio device), a vehicle component or sensor, a smart meter/sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium.

Some UEs may be considered Machine Type Communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. The wireless node may provide a connection for or to a network (e.g., a wide area network such as the internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered internet of things (IoT) devices and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered Customer Premises Equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as processor components and/or memory components. In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, etc. The frequency may also be referred to as a carrier wave, a frequency channel, etc. Each frequency in a given geographic region may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120 e) may communicate directly (e.g., without using base station 110 as an intermediary device) using one or more side-uplink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, a vehicle-to-all (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, or a vehicle-to-infrastructure (V2I) protocol, etc.), and/or a mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by base station 110.

Devices of wireless network 100 may communicate using electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices of wireless network 100 may communicate using an operating frequency band having a first frequency range (FR 1) that may span from 410MHz to 7.125GHz, and/or may communicate using an operating frequency band having a second frequency range (FR 2) that may span from 24.25GHz to 52.6GHz. The frequency between FR1 and FR2 is sometimes referred to as the mid-band frequency. Although a portion of FR1 is greater than 6GHz, FR1 is commonly referred to as the "sub-6GHz" band. Similarly, FR2 is commonly referred to as the "millimeter wave" frequency band, although it is different from the Extremely High Frequency (EHF) frequency band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" frequency band. Thus, unless specifically stated otherwise, it should be understood that the term "sub-6GHz" and the like, if used herein, may broadly represent frequencies less than 6GHz, frequencies within FR1, and/or intermediate band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, it should be understood that the term "millimeter wave" or the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and/or intermediate band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified and that the techniques described herein may be applied to these modified frequency ranges.

As described above, fig. 1 is provided as an example. Other examples may differ from the example described with respect to fig. 1.

Fig. 2 is a schematic diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100 in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234a through 234T and UE 120 may be equipped with R antennas 252a through 252R, where typically T.gtoreq.1 and R.gtoreq.1.

At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more Modulation and Coding Schemes (MCSs) for each UE based at least in part on Channel Quality Indicators (CQIs) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCSs selected for the UEs, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The processor 220 may also generate reference symbols for a reference signal (e.g., a cell-specific reference signal (CRS), or a demodulation reference signal (DMRS)) and a synchronization signal (e.g., a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS)). A Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T Modulators (MODs) 232a through 232T. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232T may be transmitted through T antennas 234a through 234T, respectively.

At UE 120, antennas 252a through 252r may receive the downlink signals from base station 110 and/or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254R, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term "controller/processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, and/or a Channel Quality Indicator (CQI) parameter, among others. In some aspects, one or more components of UE 120 may be included in housing 284.

The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may comprise, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via a communication unit 294.

Antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252 r) may include or be included in one or more antenna panels, antenna groups, sets of antenna elements and/or antenna arrays, etc. The antenna panel, antenna group, antenna element set, and/or antenna array may include one or more antenna elements. The antenna panel, antenna group, antenna element set, and/or antenna array may include a coplanar antenna element set and/or a non-coplanar antenna element set. The antenna panel, antenna group, antenna element set, and/or antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. The antenna panel, antenna group, antenna element set, and/or antenna array may include one or more antenna elements coupled to one or more transmission components and/or reception components (such as one or more components of fig. 2).

On the uplink, at UE 120, transmit processor 264 may receive and process data from data source 262 and control information from controller/processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and/or CQI). Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and demodulator (e.g., MOD/DEMOD 254) of UE 120 may be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and/or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to fig. 3-10).

At base station 110, uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 (if applicable), and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller/processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and demodulator (e.g., MOD/DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, the base station 110 comprises a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and/or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described with reference to fig. 3-10).

The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component of fig. 2 may perform one or more techniques associated with adapting PDCCH repetition in the presence of SS set handoffs, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component of fig. 2 may perform or direct operations of process 900 of fig. 9 and/or other processes described herein, for example. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include non-transitory computer-readable media storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and/or UE 120 (e.g., directly, or after compilation, conversion, interpretation, etc.), may cause the one or more processors, UE 120, and/or base station 110 to perform or direct operations such as process 900 of fig. 9 and/or other processes as described herein. In some aspects, executing the instructions may include: executing the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, etc.

In some aspects, a UE (e.g., UE 120) includes: means for receiving SS configuration information associated with a handoff between the first SS set group and the second SS set group from the base station; and/or means for receiving DCI associated with PDCCH repetition from the base station based at least in part on a handoff between the first SS set group and the second SS set group. Units for the UE to perform the operations described herein may include, for example, one or more of an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller/processor 280, or a memory 282.

In some aspects, a UE includes: means for receiving a first PDCCH repetition during a first time slot; means for receiving a second PDCCH repetition during a second time slot; and/or means for selectively monitoring the second PDCCH repetition to receive DCI when the switching is delayed from being effective after receiving the first PDCCH repetition and before receiving the second PDCCH repetition to being effective after receiving the second PDCCH repetition.

Although the blocks in fig. 2 are shown as distinct components, the functionality described above for the various blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and/or TX MIMO processor 266 may be performed by controller/processor 280 or under the control of controller/processor 280.

As described above, fig. 2 is provided as an example. Other examples may differ from the example described with respect to fig. 2.

The UE may communicate with the BS in a wireless network such as an LTE network or a 5G/NR network. The communication may include downlink communication from the BS to the UE, and may include uplink communication from the UE to the BS. The downlink communication may include control information such as Downlink Control Information (DCI) and downlink payload data.

Adequate reception of control information by the UE and uplink communication by the BS may be critical to data communication. This is because the UE can perform a communication operation related to data communication using information included in the control information. For example, the control information may include DCI indicating, for example, a resource block assignment and/or a modulation and coding scheme, which the UE may utilize to receive and decode downlink payload data.

The UE may receive DCI via a Physical Downlink Control Channel (PDCCH). The PDCCH may be received on one of the one or more PDCCH candidates. The PDCCH candidates may be associated with a Set of Search Spaces (SSs). In one example, PDCCH candidates having a given aggregation level and a given candidate index may be associated with a given SS set. The UE may monitor PDCCH candidates in the SS set and may successfully decode one or more PDCCH candidates to receive DCI.

The SS set may be associated with one or more SS set groups, which may include a first SS set group (e.g., group 0) and a second SS set group (e.g., group 1). In embodiments involving decentralized channel access, the first SS set group may be associated with a time before a Channel Occupancy Time (COT) begins. To achieve frequent channel access opportunities before the start of the COT, the UE may monitor PDCCH candidates in the SS set associated with the first SS set group with a first periodicity. The second SS set group may be associated with a time after the start of the COT. The UE may monitor PDCCH candidates in an SS set associated with the second SS set group with a second period, which may have a longer period relative to the first period. SS set group handoff may be useful in embodiments involving decentralized channel access (e.g., NR-unlicensed), but may also be applied in other embodiments.

One of the SS aggregate groups may be active at a given time. That is, at a given time, the UE may monitor PDCCH candidates in the SS set associated with the first SS set group or in the SS set associated with the second SS set group. Further, PDCCH communication between the BS and the UE may be handed over from being in the first SS set group to being in the second SS set group, and vice versa. When PDCCH communication is handed over from being in the first SS set group to being in the second SS set group, the UE may switch from monitoring PDCCH candidates in the SS set associated with the first SS set group to monitoring PDCCH candidates in the SS set associated with the second SS set group. Similarly, when PDCCH communication is handed over from being in the second SS set to being in the first SS set, the UE may switch from monitoring PDCCH candidates in the SS set associated with the second SS set to monitoring PDCCH candidates in the SS set associated with the first SS set.

In some cases, PDCCH repetition may be supported in order to achieve adequate reception of DCI. PDCCH repetition may be associated with multiple instances of the BS transmitting PDCCH candidates. For example, the BS may transmit PDCCH on a first PDCCH candidate (e.g., PDCCH repetition 1) and PDCCH on a second PDCCH candidate (e.g., PDCCH repetition 2). In one example, PDCCH repetition 1 and PDCCH repetition 2 may include substantially the same information. Two PDCCH candidates may be concatenated together so that the same DCI may be repeated. In some aspects, the two PDCCH candidates may have the same aggregation level (i.e., the same number of control channel elements), and the DCI payloads may be substantially the same. Thus, the UE may perform soft combining to decode DCI. Soft combining involves storing multiple repetitions of DCI and combining the multiple repetitions to determine the most likely value of DCI. In some aspects, two PDCCH candidates in different SS sets (associated with corresponding control resource sets (core)) may be linked together for PDCCH repetition. For example, the monitoring occasions of the first set of SSs may be linked with the monitoring occasions of the second set of SSs.

In the case of supporting PDCCH repetition and switching SS set groups, the UE may not sufficiently receive DCI. In one example, the active SS set group may be a first SS set group and may be associated with an SS set that includes PDCCH candidates, PDCCH repetition 1, and PDCCH repetition 2. In this case, the UE may monitor the PDCCH candidate, PDCCH repetition 1, and PDCCH repetition 2 to receive DCI. During monitoring, the UE may receive PDCCH repetition 1. The active SS set may be switched to the second SS set group before the UE receives PDCCH repetition 2. Based on the handoff of the active SS set group to the second SS set group, the UE may cease monitoring PDCCH candidates included in the SS set associated with the first SS set group and begin monitoring PDCCH candidates included in the SS set associated with the second SS set group. As a result, the UE may not receive PDCCH 2. In addition, if the UE fails to decode PDCCH repetition 1, the UE may not sufficiently receive DCI.

In the case where DCI is not sufficiently received, the UE may not perform a communication operation related to data communication. Accordingly, data communication between the BS and the UE may experience interruption or stop.

Various aspects of the techniques and apparatus described herein may enable adaptation of PDCCH repetition in the presence of SS set handoffs. In some aspects, the techniques and apparatus discussed herein may enable a UE to monitor PDCCH candidates while supporting PDCCH repetition and active SS sets are switched so that the UE may fully receive DCI with the benefit of PDCCH repetition. For example, the techniques and apparatus described herein may enable switching between PDCCH repetition-based monitoring (for linked monitoring occasions) and separate monitoring (for unlinked monitoring occasions). Based at least in part on adequately receiving the DCI, the UE may adequately perform communication operations related to the data communication. In this way, data communication between the BS and the UE may continue uninterrupted.

Fig. 3-8 are diagrams illustrating examples associated with adapting PDCCH repetition in the presence of SS set handoffs, in accordance with the present disclosure. Fig. 3 shows a UE 120 and BS 110 in data communication in, for example, an LTE network or a 5G/NR network. The data communication may occur on a channel and may include downlink communication from BS 110 to UE 120 and may include uplink communication from UE 120 to BS 110. The downlink communication may include DCI and downlink payload data.

As shown at reference numeral 310, BS 110 may transmit configuration information before initiation of data communication, at the beginning of data communication, and/or during data communication, and UE 120 may receive the configuration information. In some aspects, the configuration information may include an indication of one or more configuration parameters used by UE 120 to configure UE 120 for data communication, for example. In some aspects, UE 120 may receive the configuration information via system information broadcast by BS 110. In some aspects, UE 120 may receive configuration information from a device other than BS 110 (e.g., from another base station). In some aspects, UE 120 may receive the configuration information via, for example, a control channel (e.g., PDCCH) between UE 120 and BS 110. The configuration information may be conveyed via Radio Resource Control (RRC) signaling, MAC signaling (e.g., MAC control elements (MAC CEs)), DCI signaling, or a combination thereof (e.g., RRC configuration of a set of values of a parameter and DCI indication of a selected parameter value).

As shown at reference numeral 320, the configuration information may include SS configuration information associated with UE 120 monitoring PDCCH candidates to adequately receive DCI. In some aspects, based at least in part on the SS configuration information, UE 120 may be enabled to adequately receive DCI. As indicated by reference numeral 330, based at least in part on the SS configuration information, UE 120 may configure UE 120 to selectively monitor PDCCH candidates to receive DCI. PDCCH candidates may be associated with a SS set. As shown at reference numeral 340, the UE may selectively monitor PDCCH candidates in the SS set and may successfully decode one or more PDCCH candidates to receive DCI.

Further, the SS set may be associated with one or more of a first SS set group (e.g., group 0) and a second SS set group (e.g., group 1). In some aspects, SS configuration information may indicate an association of SS sets with one or more of the SS set groups. For example, SS configuration information may indicate that a first SS set (e.g., SS set x) is associated with group 0 and/or group 1, a second SS set (e.g., SS set y) is associated with group 0 and/or group 1, a third SS set (e.g., SS set z) is associated with group 0 and/or group 1, and so on.

One of the SS set groups may be an active SS set group at a given time. The SS configuration information may indicate handover information associated with a handover between SS set groups. For example, SS configuration information may indicate handover information associated with a handover between group 0 being the active SS set group and group 1 being the active SS set group. In some aspects, the handoff information may indicate an explicit handoff between SS set groups. Explicit switching may be indicated via a field including a flag bit (e.g., a search space set group switching flag bit) transmitted in, for example, DCI format 2_0. The value of the flag bit may indicate the next active SS set group. For example, a flag bit value of 0 may indicate a handoff from group 1 to group 0 being the active SS set group (e.g., from group 1 to group 0). Similarly, a flag bit value of 1 may indicate a handoff from group 0 to group 1 being the active SS set group (e.g., from group 0 to group 1). In some aspects, explicit switching may be used to switch from group 0 to group 1 or from group 1 to group 0.

In some aspects, the handoff information may indicate an implicit handoff between SS set groups. In one example, the handover information may indicate a handover between SS set groups based at least in part on UE 120 detecting and/or receiving a DCI format via PDCCH candidates included in an SS set associated with a current active SS set group. For example, the handover information may indicate a handover from, for example, group 0 to group 1 based at least in part on detecting and/or receiving a certain DCI format via PDCCH candidates included in the SS set associated with the current active group 0. In some aspects, such implicit switching may be conditioned on non-configuration of a field including a flag bit in another DCI format (such as DCI format 2_0) (e.g., when a field including a flag bit in DCI format 2_0 is not configured, for example). In some aspects, such implicit switching may be ineffective for indicating a switch from group 1 to group 0.

In some aspects, implicit switching may include switching between SS set groups based at least in part on expiration of a timer. For example, SS configuration information may indicate: UE 120 will start a timer when group 1 becomes the active SS set group and an expiration of the timer indicates a switch from group 1 to group 0. In some aspects, the UE may set a duration associated with the timer based at least in part on a timer field (e.g., searchSpaceSwitchingTimer) included in the received DCI. In some aspects, such a timer-based implicit switch may be ineffective for indicating a switch from group 0 to group 1.

In some aspects, the COT end indication may indicate a switch from group 1 to group 0 when data communication occurs over an unlicensed frequency band.

Based at least in part on the handover information, UE 120 may configure UE 120 to monitor PDCCH candidates in the SS set associated with the active SS set group. For example, when the active SS set group switches from group 0 to group 1, UE 120 may cease monitoring PDCCH candidates included in the SS set associated with group 0 and may begin monitoring PDCCH candidates included in the SS set associated with group 1, and vice versa.

The handoff information may also indicate a timeline associated with handoffs between SS set groups. For example, a delay field (e.g., searchSpaceSwitchingDelay-r 16) may indicate a delay duration associated with a handoff between SS set groups. Based at least in part on the delay duration, UE 120 may delay monitoring of PDCCH candidates included in the SS set associated with the next active SS set group. In some aspects, the delay duration may be equal to or greater than a predetermined number of symbols (e.g., P _switch ) The associated durations are correlated. Further, the handover information may indicate: UE 120 will begin monitoring PDCCH candidates included in the SS set associated with the next active SS set group at the beginning of the first slot, at least P after the handoff indication _switch Beginning after a symbol.

For example, as shown in the example of fig. 4A, when the handover information indicates explicit and/or implicit handover via DCI received during slot 1, UE 120 may configure UE 120 to: by counting P after DCI is received _switch The delay duration is determined by the symbols. In some aspects, the end of the delay duration may be during another time slot (time slot 2). UE 120 may begin monitoring PDCCH candidates included in the SS set associated with the next active SS set group at the beginning of a first time slot (slot 3) at least P after the handoff indication _switch Beginning after a symbol.

Similarly, as shown in the example of fig. 4B, when the handover information indicates a handover based at least in part on expiration of the timer during slot 1, UE 120 may configure UE 120 to: by counting P after expiration _switch The delay duration is determined by the symbols. In some aspects, the end of the delay duration may be during another time slot (time slot 2). UE 120 may begin monitoring PDCCH candidates included in the SS set associated with the next active SS set group at the beginning of a first time slot (slot 3) at least P after the handoff indication _switch Beginning after a symbol.

In some aspects, SS configuration information may indicate that PDCCH repetition is supported. PDCCH repetition may be associated with multiple instances of BS 110 transmitting PDCCH candidates. For example, BS 110 may transmit a first PDCCH candidate (e.g., PDCCH repetition 1) and transmit a second PDCCH candidate (e.g., PDCCH repetition 2). In one example, PDCCH repetition 1 and PDCCH repetition 2 may be concatenated together to repeatedly transmit substantially the same information (e.g., the same DCI). The link between the first PDCCH candidate/repetition and the second PDCCH candidate/repetition may also be referred to and/or may be similar to a link between a first SS set including the first PDCCH candidate/repetition and a second SS set including the second PDCCH candidate/repetition. In some aspects, PDCCH repetition 1 and PDCCH repetition 2 may be linked together by having, for example, the same aggregation level associated with having the same number of Control Channel Elements (CCEs). In this disclosure, "PDCCH candidates" may refer to "PDCCH repetition" and vice versa.

In some aspects, SS configuration information may indicate that PDCCH repetition may be associated with different SS sets. For example, the SS configuration information may indicate that PDCCH repetition 1 is included in, for example, SS set x, and PDCCH repetition 2 is included in, for example, SS set y. In this case, UE 120 may determine that the monitoring occasion associated with monitoring PDCCH repetition 1 is linked to the monitoring occasion associated with monitoring PDCCH repetition 2. In some aspects, the SS configuration information may indicate that PDCCH repetition 1 and linked PDCCH repetition 2 are to be received during the same time slot (e.g., intra-slot repetition). In some aspects, SS configuration information may indicate that PDCCH repetition 1 and linked PDCCH repetition 2 are to be received during different time slots (e.g., inter-slot repetition).

In some aspects, the SS configuration information may indicate information associated with PDCCH repetition 1 and PDCCH repetition 2 to enable UE 120 to determine that PDCCH repetition 1 is linked to PDCCH repetition 2. In one example, the SS configuration information may indicate that PDCCH candidates included in different SS sets may be linked together for PDCCH repetition by being configured with, for example, the same candidate index. In another example, the SS configuration may indicate that PDCCH candidates may be linked together by being configured to have, for example, the same starting CCE index.

As shown in reference numeral 340 of fig. 3, UE 120 may selectively monitor PDCCH candidates to receive DCI based at least in part on the SS configuration information. In some aspects, as shown in the example of fig. 5A, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) associated with a first SS set group (e.g., set 0), linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y) associated with a second SS set group (e.g., set 1).

In some aspects, UE 120 may treat such a configuration of PDCCH repetition (e.g., PDCCH repetition 1 associated with group 0 and PDCCH repetition 2 associated with group 1) as an error based at least in part on determining that UE 120 may selectively monitor PDCCH repetition associated with a single set of SSs currently active.

In some aspects, based at least in part on the SS configuration information indicating such a configuration of PDCCH repetition, UE 120 may selectively monitor the first PDCCH repetition or the second PDCCH repetition to receive DCI. In one example, UE 120 may monitor for a first PDCCH repetition when the first SS set group is active and UE 120 may monitor for a second PDCCH repetition when the second SS set group is active.

In some aspects, based at least in part on the SS configuration information indicating such a configuration of PDCCH repetition, UE 120 may determine that UE 120 is to selectively monitor PDCCH repetition by ignoring a link between the first PDCCH repetition and the second PDCCH repetition. In this case, the UE 120 may separately monitor the first PDCCH repetition when the first SS set group is active, and the UE 120 may separately monitor the second PDCCH repetition when the second SS set group is active. The link between the first PDCCH repetition and the second PDCCH repetition may also be referred to as a link between a first SS set including the first PDCCH repetition and a second SS set including the second PDCCH repetition.

In some aspects, based at least in part on the SS configuration information indicating such configuration of PDCCH repetitions, UE 120 may determine that UE 120 is to selectively monitor PDCCH repetitions by determining that the second PDCCH repetition is also associated with the first SS set group and/or that the first PDCCH repetition is also associated with the second SS set group. In one example, based at least in part on the first PDCCH repetition being linked to the second PDCCH repetition, UE 120 may determine that the second PDCCH repetition is also associated with the first SS set group and/or the first PDCCH repetition is also associated with the second SS set group. In this case, the UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI. In some aspects, the link between the first PDCCH repetition and the second PDCCH repetition may also be referred to as a link between a first SS set including the first PDCCH repetition and a second SS set including the second PDCCH repetition.

In some aspects, SS configuration information may indicate: the first SS set and the second SS set may be associated with a first SS set group, and at least one of the first SS set or the second SS set may not be associated with a second SS set group. In one example, as shown in example 1 of fig. 5B, SS configuration information may indicate: the PDCCH repetition may include a first PDCCH repetition (e.g., PDCCH repetition 2) included in a first SS set (e.g., SS set y) associated with a first SS set group (e.g., set 0) and a second SS set group (e.g., set 1), linked to a second PDCCH repetition (e.g., PDCCH repetition 1) included in a second SS set (e.g., SS set x) associated with the first SS set group (e.g., set 0). Based at least in part on the SS configuration information indicating such a configuration, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition based at least in part on switching to the first SS set group (e.g., group 0) as the active SS set group. That is, when group 0 becomes an active SS set group, UE 120 may monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI with the benefit of the PDCCH repetition.

In another example, as shown in example 2 of fig. 5B, SS configuration information may indicate: the PDCCH repetition may include a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) associated with a first SS set group (e.g., set 0) and a second SS set group (e.g., set 1), linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y) associated with a second SS set group (e.g., set 1). Based at least in part on the SS configuration information indicating such a configuration, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition based at least in part on switching to the second SS set group (e.g., group 1) as the active SS set group. That is, when group 1 becomes an active SS set group, UE 120 may monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI with the benefit of the PDCCH repetition.

As shown in example 3 of fig. 5B, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) associated with a first SS set group (e.g., set 0), linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y) associated with the first SS set group (e.g., set 0). In this case, both SS set x and SS set y may not be associated with group 1. Based at least in part on the SS configuration information indicating such a configuration, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition based at least in part on switching to the first SS set group (e.g., group 0) as the active SS set group. That is, when group 0 becomes an active SS set group, UE 120 may monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI with the benefit of the PDCCH repetition.

In some aspects, the configuration discussed with respect to fig. 5B may enable dynamic indication of PDCCH repetition. For example, BS 110 may dynamically enable and/or disable PDCCH repetition by dynamically switching between the first SS set group and the second SS set group (e.g., via DCI). As discussed above with respect to examples 1 and 2 of fig. 5B, when both the first SS set and the second SS set are associated with a given set of SS sets that are active, UE 120 may selectively monitor PDCCH repetition associated with the first SS set and the second SS set. In this case, PDCCH repetition may be enabled or supported. When the configuration information indicates a handover to another SS set group associated with one of the first SS set and the second SS set, UE 120 may selectively monitor PDCCH candidates included in the SS set associated with the other SS set group. In this case, PDCCH repetition may not be enabled or supported.

In some aspects, the SS configuration information may indicate that each SS set including PDCCH repetition among the plurality of SS sets is associated with a plurality of SS search set groups. For example, as shown in the example of fig. 5C, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) associated with a first SS set group (e.g., set 0) and a second SS set group (e.g., set 1), linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y) associated with the first SS set group (e.g., set 0) and the second SS set group (e.g., set 1). In this case, since PDCCH repetition is associated with two SS set groups, UE 120 may choose to monitor the first PDCCH repetition and the second PDCCH repetition regardless of which SS set group is active.

In some aspects, as shown in fig. 6, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) associated with a first SS set (e.g., set 0) and a second SS set (e.g., set 1), linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y) associated with the first SS set (e.g., set 0), linked to a third PDCCH repetition (e.g., PDCCH repetition 3) included in a third SS set (e.g., SS set z) associated with the second SS set (e.g., set 1). In some aspects, the first PDCCH repetition may be concatenated to the second PDCCH repetition to receive the first DCI, and the first PDCCH repetition may be concatenated to the third PDCCH repetition to receive the second DCI, which may be different relative to the first DCI. Based at least in part on the SS configuration indicating such a configuration, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition based at least in part on switching to the first SS set group. That is, when group 0 is active, UE 120 may monitor for a first PDCCH repetition and a second PDCCH repetition. In addition, UE 120 may selectively monitor the first PDCCH repetition and the third PDCCH repetition based at least in part on switching to the second SS set group. That is, when group 1 is active, UE 120 may monitor for a first PDCCH repetition and a third PDCCH repetition.

In some aspects, the configuration discussed with respect to fig. 6 may enable dynamic indication of PDCCH repetition. For example, BS 110 may dynamically enable and/or disable PDCCH repetition by dynamically switching between the first SS set group and the second SS set group (e.g., via DCI). Further, as shown in fig. 6, UE 120 may receive PDCCH repetition 1 included in SS set x and PDCCH repetition 2 included in SS set y during a given slot, thereby indicating intra-slot PDCCH repetition. Further, as shown in fig. 6, UE 120 may receive PDCCH repetition 1 included in SS set x and PDCCH repetition 3 included in SS set z during different slots, thereby indicating inter-slot PDCCH repetition. In this case, BS 110 may indicate dynamic switching between intra-slot PDCCH repetition and inter-slot PDCCH repetition by switching between SS set groups.

In some aspects, as shown in fig. 7, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., SS set y), the first SS set (e.g., SS set x) and the second SS set (e.g., SS set y) being associated as a pair with a first SS set group (e.g., set 0). Based at least in part on the SS configuration information indicating such a configuration, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition based at least in part on switching to the first SS set group. In this case, the first SS set and the second SS set may be associated with a given SS set group as a pair, and based at least in part on the first SS set and the second SS set being associated with the given SS set group as a pair, UE 120 may selectively monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI. That is, when group 0 is active, UE 120 may monitor the first PDCCH repetition and the second PDCCH repetition to receive DCI with the benefit of the PDCCH repetition.

In the event that the first PDCCH repetition (or first SS set) is not linked to the second PDCCH repetition (or second SS set) and/or the first SS set and the second SS set are not associated as a pair with a given SS set group (e.g., group 1), UE 120 may choose to monitor PDCCH candidates included in the first SS set and PDCCH candidates included in the second SS set, respectively, to receive DCI without assuming PDCCH repetition.

In some aspects, as shown in fig. 8, SS configuration information may indicate: the PDCCH repetition includes a first PDCCH repetition (e.g., PDCCH repetition 1) included in a first SS set (e.g., SS set x) linked to a second PDCCH repetition (e.g., PDCCH repetition 2) included in a second SS set (e.g., set y). Further, the configuration information may indicate: the first SS set may be associated with a first SS set group (e.g., group 0) and a second SS set group (e.g., group 1), and the second SS set may be associated with a second SS set group (e.g., group 1). UE 120 may receive a first PDCCH repetition during a first time slot (e.g., time slot 2) and may receive a second PDCCH repetition during a different time slot (e.g., time slot 3), indicating inter-time-slot PDCCH repetition. Further, during slot 1, the handover information included in the SS configuration information may indicate a handover from group 1 to group 0 such that the handover is effective after receiving the first PDCCH repetition and before receiving the second PDCCH repetition (e.g., by counting P _switch A symbol to end the delay duration).

In one example, based at least in part on the configuration information indicating such a configuration, UE 120 may determine that PDCCH repetition is no longer supported. Further, based at least in part on group 0 becoming the active group, UE 120 may choose to monitor the second PDCCH repetition to receive DCI without the benefit of PDCCH repetition. In this case, UE 120 may also monitor other PDCCH candidates included in the SS set associated with group 0 to receive DCI.

In another example, based at least in part on the configuration information indicating such a configuration, UE 120 may determine that PDCCH repetition is no longer supported and may choose to refrain from monitoring for a second PDCCH repetition. In this case, preventing monitoring the second PDCCH repetition may enable BS 110 and UE 120 to avoid erroneously receiving DCI depending on the benefit of UE 120 utilizing PDCCH repetition.

In yet another example, based at least in part on the configuration information indicating such a configuration, BS 110 may transmit and UE 120 may receive an indication to delay switching from group 1 to group 0 until after receiving the second PDCCH repetition (e.g., until the beginning of slot 4). In this case, UE 120 may choose to monitor the second PDCCH repetition to receive DCI with the benefit of the PDCCH repetition.

By utilizing aspects of the techniques and apparatus described herein, when PDCCH repetition is supported and an active SS set group is handed over, a UE may be enabled to monitor PDCCH candidates so that the UE may adequately receive DCI with the benefits of PDCCH repetition. Based at least in part on adequately receiving the DCI, the UE may adequately perform communication operations related to the data communication. In this way, data communication between the BS and the UE may continue uninterrupted.

As described above, fig. 3-8 are provided as examples. Other examples may differ from the examples described with respect to fig. 3-8.
