Description

USER EQUIPMENT SELECTION OF SYNCHRONIZATION SIGNAL BLOCK CYCLE

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for user equipment (UE) selection of a synchronization signal block (SSB) cycle.

BACKGROUND

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like) . Examples of such multiple-access technologies 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 promulgated by the Third Generation Partnership Project (3GPP) .

A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs) . A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the 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, a gNB, an access point (AP) , a radio head, a transmit receive point (TRP) , a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New Radio (NR) , which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP) . NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) , using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) ) on the uplink (UL) , as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

SUMMARY

In some aspects, a method of wireless communication, performed by a user equipment, may include receiving, from a network entity, information indicating a set of synchronization signal block (SSB) cycles, each SSB cycle in the set having an associated length; selecting an SSB cycle from the set of SSB cycles; and transmitting information indicating the selected SSB cycle.

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 combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the 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 a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, and/or the like (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or combinations 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 while aspects may be described herein using terminology commonly associated with a 5G or NR radio access technologies (RAT) , aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G) .

Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with various aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, and/or the like. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB) , an access point, a transmit receive point (TRP) , and/or the like. 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 this coverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell 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 restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG) ) . A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Fig. 1, a BS 110a may be a macro BS for a macro cell 102a, a BS 110b may be a pico BS for a pico cell 102b, and a BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB” , “base station” , “NR BS” , “gNB” , “TRP” , “AP” , “node B” , “5G NB” , and “cell” may be used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another 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 a direct physical connection, a virtual network, and/or the like using any suitable transport network.

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

Wireless network 100 may be a heterogeneous network that includes BSs of different types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts) .

A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE may be a cellular phone (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, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet) ) , an entertainment device (e.g., a music or video device, or a satellite radio) , a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via 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, location tags, and/or the like, that may communicate with a base station, another device (e.g., remote device) , or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as 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 a Customer Premises Equipment (CPE) . UE 120 may be included inside a housing that houses components of UE 120, such as processor components, memory components, and/or the like. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, and/or the like.

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, and/or the like. A frequency may also be referred to as a carrier, a frequency channel, and/or the like. Each frequency may support a single RAT in a given geographic area in order 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 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another) . For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, and/or the like) , a mesh network, and/or the like. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with various aspects of 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 in general T ≥ 1 and R ≥ 1.

At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS (s) selected for the UE, 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/or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and/or the like) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) , a demodulation reference signal (DMRS) , and/or the like) and synchronization signals (e.g., the primary synchronization signal (PSS) and 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 and/or the like) 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 via 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 and/or the like) to obtain received symbols. A 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. A 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. A channel processor may determine reference signal received power (RSRP) , received signal strength indicator (RSSI) , reference signal received quality (RSRQ) , channel quality indicator (CQI) , and/or the like. In some aspects, one or more components of UE 120 may be included in a housing 284.

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

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor 280. 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, CP-OFDM, and/or the like) , and transmitted to base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna (s) 252, modulators and/or demodulators 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, for example, as described with reference to Figs. 3-6.

At base station 110, the 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. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna (s) 234, modulators and/or demodulators 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, for example, as described with reference to Figs. 3-6.

Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform one or more techniques associated with UE selection of an SSB cycle, 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 (s) of Fig. 2 may perform or direct operations of, for example, process 500 of Fig. 5, process 600 of Fig. 6, and/or other processes as described herein.

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 a non-transitory computer-readable medium storing one or more instructions (e.g., code, program code, and/or the like) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, interpreting, and/or the like) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 500 of Fig. 5, process 600 of Fig. 6, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, and/or the like.

In some aspects, UE 120 may include means for receiving, from a network entity, information indicating a set of synchronization signal block (SSB) cycles, each SSB cycle in the set having an associated length (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or the like) ; means for selecting an SSB cycle from the set of SSB cycles (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or the like) ; means for transmitting information indicating the selected SSB cycle (e.g., using controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, and/or the like) ; means for receiving an SSB in accordance with a final SSB cycle, wherein the final SSB cycle is selected based at least in part on the information indicating the selected SSB cycle (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or the like) ; and/or the like. In some aspects, such means may include one or more components of UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

In some aspects, such means may include one or more components of base station 110 described in connection with Fig. 2, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

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

As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

Fig. 3 is a diagram illustrating an example 300 of a synchronization signal (SS) hierarchy, in accordance with various aspects of the present disclosure. As shown in Fig. 3, the SS hierarchy may include an SS burst set 305, which may include multiple SS bursts 310, shown as SS burst 0 through SS burst N-1, where N is a maximum number of repetitions of the SS burst 310 that may be transmitted by the base station. As further shown, each SS burst 310 may include one or more SS blocks (SSBs) 315, shown as SSB 0 through SSB M-1, where M is a maximum number of SSBs 315 that can be carried by an SS burst 310. In some aspects, different SSBs 315 may be beam-formed differently (e.g., transmitted using different beams) , and may be used for beam management, beam selection, and/or the like (e.g., as part of an initial network access procedure) . An SS burst set 305 may be periodically transmitted by a wireless node (e.g., base station 110) , such as every X milliseconds, as shown in Fig. 3. In some aspects, an SS burst set 305 may have a fixed or dynamic length, shown as Y milliseconds in Fig. 3. In some cases, an SS burst set 305 or an SS burst 310 may be referred to as a discovery reference signal (DRS) transmission window, an SSB measurement time configuration (SMTC) window, and/or the like.

In some aspects, an SSB 315 may include resources that carry a primary synchronization signal (PSS) 320, a secondary synchronization signal (SSS) 325, a physical broadcast channel (PBCH) 330, and/or the like. In some aspects, multiple SSBs 315 are included in an SS burst 310 (e.g., with transmission on different beams) , and the PSS 320, the SSS 325, and/or the PBCH 330 may be the same across each SSB 315 of the SS burst 310. In some aspects, a single SSB 315 may be included in an SS burst 310. In some aspects, the SSB 315 may be at least four symbols (e.g., OFDM symbols) in length, where each symbol carries one or more of the PSS 320 (e.g., occupying one symbol) , the SSS 325 (e.g., occupying one symbol) , and/or the PBCH 330 (e.g., occupying two symbols) . In some aspects, an SSB 315 may be referred to as an SS/PBCH block.

In some aspects, the symbols of an SSB 315 are consecutive, as shown in Fig. 3. In some aspects, the symbols of an SSB 315 are non-consecutive. Similarly, in some aspects, one or more SSBs 315 of the SS burst 310 may be transmitted in consecutive radio resources (e.g., consecutive symbols) during one or more slots. Additionally, or alternatively, one or more SSBs 315 of the SS burst 310 may be transmitted in non-consecutive radio resources.

In some aspects, the SS bursts 310 may have a burst period, and the SSBs 315 of the SS burst 310 may be transmitted by a wireless node (e.g., base station 110) according to the burst period. In this case, the SSBs 315 may be repeated during each SS burst 310. In some aspects, the SS burst set 305 may have a burst set periodicity, whereby the SS bursts 310 of the SS burst set 305 are transmitted by the wireless node according to the fixed burst set periodicity. In other words, the SS bursts 310 may be repeated during each SS burst set 305.

In some aspects, an SSB 315 may include an SSB index, which may correspond to a beam used to carry the SSB 315. A UE 120 may monitor for and/or measure SSBs 315 using different receive (Rx) beams during an initial network access procedure. Based at least in part on the monitoring and/or measuring, the UE 120 may indicate one or more SSBs 315 with a best signal parameter (e.g., a reference signal received power (RSRP) parameter and/or the like) to a base station 110. The base station 110 and the UE 120 may use the one or more indicated SSBs 315 to select one or more beams to be used for communication between the base station 110 and the UE 120 (e.g., for a random access channel (RACH) procedure and/or the like) . Additionally, or alternatively, the UE 120 may use the SSB 315 and/or the SSB index to determine a cell timing for a cell via which the SSB 315 is received (e.g., a serving cell) .

In some aspects, SS bursts 310 may be separated from each other by a length of time, which may be defined by an SSB cycle. For example, the SSB cycle may identify a length of time shown in Fig. 3 as Z. Z may be determined by a base station (e.g., BS 110) based at least in part on a selected SSB cycle length indicated by one or more UEs (e.g., UE 120) . For example, according to techniques and apparatuses described herein, the base station may select a final SSB cycle length based at least in part on respective selected SSB cycle lengths indicated by the one or more UEs. In some aspects, the SSB cycle may refer to X in Fig. 3, meaning that the SSB cycle may refer to the periodicity between SSB sets 305. In some aspects, the SSB cycle may refer to a periodicity between SSBs 315.

As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

A UE may perform various operations using SSBs, such as initial network access, radio link failure recovery, beam selection in connection with beam failure recovery, and/or the like. For example, the UE may select a beam for initial network access, radio link failure recovery, or beam failure recovery based at least in part on a measurement on an SSB transmitted using the beam. Thus, a connection or recovery time of the UE may be at least partially dependent on a length of time between transmissions of SSBs. This length of time is referred to herein as an SSB cycle.

5G/NR provides various quality of service (QoS) levels for traffic carried via a 5G/NR network. For example, 5G/NR may provide for ultra-reliable, low-latency communication (URLLC) . URLLC may provide minimum latency and reliability requirements for network traffic associated with a URLLC QoS level. In some aspects, URLLC’s reliability and low latency thresholds may be defined relative to a worst case value opposed to an average value for some UE types or traffic types, such as a mission critical UE type or traffic type. For example, if a reliability or latency threshold is defined relative to a worst case value, then a communication may fail the reliability or latency threshold if any part of the communication fails the reliability or latency threshold, even if an average value associated with the communication satisfies the reliability or latency threshold. Therefore, a beam failure can lead to a failure of a URLLC condition, even in a network configured to carry URLLC traffic. For example, a URLLC radio access network (RAN) may be expected to provide an average of a 10 ms network transition latency between beams, so a beam failure or radio link failure may cause failure of some reliability or latency thresholds, such as UE critical latency or reliability requests. Furthermore, beam failure may be expected to occur more frequently than radio link failure in 5G/NR networks, thus leading to more frequent failure of URLLC conditions. As mentioned above, a longer time between SSBs may negatively impact the beam failure recovery time of the UE, leading to an increased rate of failure of URLLC conditions. However, a shorter time between SSB may lead to increased resource usage of the UE in connection with monitoring the SSBs and of a base station in connection with transmitting the SSBs.

Some techniques and apparatuses described herein provide selection of an SSB cycle (e.g., a length associated with the SSB cycle) based at least in part on an indication by a UE of a selected SSB cycle. For example, the UE may select an SSB cycle based at least in part on a condition at the UE (e.g., a mobility condition, a reliability or latency condition, a coverage condition, a power condition, and/or the like) , and may report the selected SSB cycle to a BS. A shorter SSB cycle may improve adherence to latency and reliability requirements, whereas a longer SSB cycle may reduce resource consumption of the UE and the base station. The base station may select a final SSB cycle (e.g., an SSB cycle to be used by the base station) based at least in part on the selected SSB cycle indicated by the UE and/or other UEs covered by the base station. Thus, the UE may indicate a selected SSB cycle to the base station, and the base station may take the selected SSB cycle into account when selecting a final SSB cycle. By indicating the selected SSB cycle, the UE may increase the likelihood of implementing a shortened SSB cycle that can satisfy the stringent latency and reliability requirements of URLLC, or may conserve battery and communication resources when such latency and reliability requirements are not a concern. Furthermore, the BS may conserve resources that are otherwise used to retransmit failed URLLC transmissions, and may improve conformance with URLLC requirements.

Fig. 4 is a diagram illustrating an example 400 of signaling associated with a UE selection of an SSB cycle, in accordance with various aspects of the present disclosure. As shown, example 400 includes a UE 120 and a BS 110. The BS 110 may include or be associated with a network entity. The network entity, for example, may include a gNB, a next generation radio access network (NG-RAN) , a central unit, and/or the like.

As shown by reference number 410, the BS 110 may provide, to the UE 120, information indicating a set of SSB cycles. As further shown the set of SSB cycles may be associated with respective lengths. For example, two or more SSB cycles of the set of SSB cycles may have different lengths from each other. The length of an SSB cycle may be, for example, 1 ms, 2 ms, 2.5 ms, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 120 ms, or another value. A shorter SSB cycle may provide quicker beam failure recovery, whereas a longer SSB cycle may involve increased reception resource usage at the UE 120 and transmission resource usage at the BS 110. In some aspects, the set of SSB cycles may be based at least in part on a service to be provided by the BS 110. For example, if the BS 110 is to provide a URLLC service for a set of UEs 120, the BS 110 may provide a set of SSB cycles corresponding to a URLLC service. As another example, if the BS 110 is to provide a vehicular communication service, the BS 110 may provide a set of SSB cycles corresponding to a vehicular communication service.

As shown by reference number 420, the UE 120 may select a selected SSB cycle. For example, the UE 120 may select the selected SSB cycle based at least in part on a length of the selected SSB cycle. The UE 120 may select the SSB cycle based at least in part on one or more conditions at the UE 120. For example, in some aspects, the UE 120 may be associated with a URLLC requirement (e.g., the UE 120 may be a mission critical UE, the UE 120 may be associated with a QoS flow that is associated with a URLLC requirement, and/or the like) . In this case, the UE 120 may select the SSB cycle based at least in part on a latency condition or a reliability condition associated with the URLLC requirement. For example, the UE 120 may select an SSB cycle associated with a shorter length (e.g., 1 ms, 2 ms, 5 ms, and/or the like) so that beam recovery can be performed sufficiently quickly to satisfy the latency condition or the reliability condition. In some aspects, the UE 120 may select the SSB cycle based at least in part on a battery condition of the UE 120. For example, the UE 120 may select a longer SSB cycle if the UE 120 is a low power UE, or may select a longer SSB cycle if the UE 120 is associated with a low battery condition (e.g., if remaining battery power of a battery of the UE 120 fails to satisfy a threshold) .

In some aspects, the UE 120 may select the SSB cycle length based at least in part on a motion state of the UE 120. For example, if the UE 120 is associated with a motion state that satisfies a threshold (e.g., a threshold speed, a threshold acceleration, a threshold number of cells or beams that have failed in a length of time, and/or the like) , then the UE 120 may request a shorter SSB cycle, and if the UE 120 is associated with a motion state that fails to satisfy the threshold, then the UE 120 may request a longer SSB cycle. In some aspects, the UE 120 may select the SSB cycle length based at least in part on another condition, such as a traffic condition, a number of other UEs near the UE 120, a coverage state of the UE 120, a feature set of the UE 120 (e.g., whether the UE 120 supports URLLC communication) , and/or the like.

As shown by reference number 430, the UE 120 may provide information indicating the selected SSB cycle. In some aspects, the UE 120 may provide information indicating multiple SSB cycle lengths. For example, the UE 120 may provide information indicating a selected SSB cycle length and/or a range of acceptable SSB cycle lengths, information indicating a maximum SSB cycle length or a minimum SSB cycle length, and/or the like. The information indicating the selected SSB cycle may include information indicating a length of the selected SSB cycle, an index corresponding to the selected SSB cycle, and/or the like.

As shown by reference number 440, the BS 110 may determine a final SSB cycle length. The final SSB cycle length may identify an SSB cycle length used by the BS 110 to transmit SSBs. For example, the BS 110 may transmit an SSB 450, and may transmit a next SSB 460 after the length of the final SSB cycle shown by reference number 470. In some aspects, the BS 110 may configure the final SSB cycle length for the UE 120 and/or the BS 110. As used herein, a final SSB cycle length refers to an SSB cycle length determined by the BS 110 based at least in part on a selected SSB cycle length. In some aspects, the BS 110 may determine the final SSB cycle length based at least in part on the selected SSB cycle length. For example, the BS 110 may use the selected SSB cycle length as the final SSB cycle length. As another example, the BS 110 may use the selected SSB cycle length as a factor for determining the final SSB cycle length.

In some aspects, the BS 110 may determine the final SSB cycle length based at least in part on information indicating selected SSB cycle lengths for multiple UEs 120, such as multiple UEs 120 covered by the BS 110. In this case, the BS 110 may determine the final SSB cycle length based at least in part on a policy. For example, the BS 110 may use an average SSB cycle length of the selected SSB cycle lengths, a shortest SSB cycle length of the selected SSB cycle lengths, and/or the like. As another example, the BS 110 may determine the final SSB cycle length as a most-selected SSB cycle length. In this case, the BS 110 may determine the final SSB cycle length as a cycle length that was most frequently requested by the multiple UEs 120. Thus, the BS 110 may determine a final SSB cycle length based at least in part on selected SSB cycle lengths of one or more UEs 120, thereby improving reliability and latency, or reducing communication resource consumption, depending on the selected SSBs of the UEs 120.

As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.

As shown in Fig. 6, in some aspects, process 600 may include transmitting, to a UE, information indicating a set of SSB cycles, each SSB cycle in the set having an associated length (block 610) .
