[0022] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0023] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to inter-operator spectrum sharing. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0024] It should be noted that spectrum sharing may refer to a set of procedures performed by a User Equipment (UE) and / or a network node to manage the allocation of data carriers, to sense and / or to sense signal strength (e.g., Received Signal Strength Indicator (RSSI) , etc. ) or signal quality (e.g., Reference Signal Received Power (RSRP) , Reference Signal Received Quality (RSRQ) , Signal to Interference Noise Ratio (SINR) , etc. ) of the UE.
[0025] FIG. 1 is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. Scenario 100 involves a UE and at least two network nodes, which may be a part of a wireless communication network (e.g., an LTE network, a Fifth Generation (5G) / New Radio (NR) network, an IoT network, or a Sixth Generation (6G) network) . Scenario 100 illustrates the current network framework. The UE may connect to the network side. The network side may comprise at least network node 120 and network node 130. Network node 120 may connect to network node 130 through wired or wireless connections. For illustrative purposes, one or two network nodes and one UE may be described hereinafter. However, it is not intended to limit the network scenarios of the present disclosure. In the present disclosure, several sensing and carrier control procedures may be implemented in the network nodes and the UE for spectrum sharing between two network nodes.
[0026] In the present disclosure, network node 120 may be the primary network node, and network node 130 may be the secondary network node. In some implementations, network node 120 may be a Primary cell (Pcell) , and network node 130 may be a Secondary cell (Scell) . In some implementations, network node 120 may be a primary base station, and network node 130 may be a secondary base station. In some implementations, network node 120 may belong to a first operator, network node 130 may belong to a second operator, and the first and second operators may be different operators. In some implementations, network node 120 and network node 130 may belong to the same operator. In one example, network node 120 and network node 130 may belong to the same serving network. In another example, network node 120 and network node 130 may belong to different serving networks. Network node 120 may share the licensed or unlicensed spectrum of the first operator with network node 130. In one example, network node 120 may share the licensed or unlicensed spectrum of the first operator with network node 130 in an event that some conditions are satisfied. Network node 120 and network node 130 may be co-located or non-collocated. Network node 120 may communicate with UE 110 via a primary channel or carrier, and network node 130 may perform data transmission or reception with a UE via a secondary channel or carrier. Network node 120 and network node 130 may perform timing synchronization with each other if necessary. Network node 130 may receive spectrum sharing information from a primary network node (i.e., network node 120) . The spectrum sharing information may include a sensing window, a spectrum sharing window, and a sensing signal configuration. The spectrum sharing information may include activation information. UE 110 may receive activation information and a configuration from a primary network node (i.e., network node 120) . The configuration may include a sensing configuration and a sensing signal configuration. The sensing configuration may configure a sensing window. The activation information may indicate whether to activate a secondary channel or carrier.
[0027] FIG. 2A is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In the present disclosure, network node 120 and network node 130 may exchange coordination and information. The coordination and information may include the starting time, length, and periodicity of the sensing window, the starting time and length of the spectrum sharing window, and the sensing signal configuration. The spectrum sharing information may include activation information that indicates whether to activate a secondary channel or carrier. UE 110 may receive the starting time and length of the spectrum sharing window and the sensing signal configuration via a higher-layer signaling (e.g., System Information Block (SIB) , UE-specific Radio Resource Control (RRC) signaling, etc. ) or a layer 1 (L1) signaling (e.g., Downlink Control Information (DCI) ) from network node 120. The sensing signal configuration may include a sequence format, an initial seed, time-frequency resources, etc. UE may send sensing signal (s) . In one example, UE 110 may transmit a sensing signal on a serving beam with network node 120 during the sensing window based on the sensing signal configuration received from network node 120. Network node 130 (i.e., the secondary base station or the secondary operator) may perform sensing according to the sensing signal configuration. In one example, network node 130 may perform channel sensing during the sensing window according to the sensing signal configuration. In one example, network node 130 may perform beam-based sensing during the sensing window according to the sensing signal configuration. In one example, network node 130 may perform the beam-based sensing during the sensing window for a single UE. In one example, network node 130 may perform the beam-based sensing during the sensing window for multiple UEs the first operator serves. In one example, network node 130 may notify network node 120 of the total number of beams of network node 130, and network node 130 may perform the beam-based sensing within all beams of network node 130. In one example, network node 130 may notify network node 120 of the number of beams of network node 130 that are overlapped with the frequency spectrum of network node 120, and network node 130 may perform the beam-based sensing within the beams of network node 130 overlapped with the frequency spectrum of network node 120. Network node 130 may identify which transmit / receive (Tx / Rx) beam (s) are usable on the secondary channel or carrier. Network node 130 may determine whether a beam of itself is usable for data transmission on the secondary channel or carrier based on the sensing. In one example, network node 130 may determine that the beam of itself is usable in an event that a measurement result for the beam is below a threshold. Network node 130 may communicate with UE 110 on the secondary channel or carrier on the usable beam. In one example, network node 130 may schedule downlink and uplink data on the secondary channel or carrier on the usable beam during the spectrum sharing window. UE 110 may determine whether to communicate with network node 130 based on the activation information.
[0028] FIG. 2B is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, as option 1 illustrated in FIG. 2B, all primary UEs served by the same or different base stations, belonging to the primary operator, may simultaneously transmit a sensing signal using the serving beam on the overlapped time and frequency resource. The sensing signal may be the same for all primary UEs. The sensing signal may be a data channel or a reference signal configured or triggered by the primary network node (e.g., network node 120) . The sensing signal may be repeated N times, where N may be the number of beams of the network node 130. In one example, as option 1 illustrated in FIG. 2B, all primary UEs may transmit the sensing signal four times during the sensing window. Network node 130 may perform beam-based sensing once during the sensing window for all UEs according to the sensing signal configuration. In one example, network node 130 may determine that the beam of network node 130 is usable in an event that a Received Signal Strength Indicator (RSSI) measurement result of a received sensing signal for the beam is below an RSSI threshold. Notably, the received sensing signal may be a mixed signal from all UEs.
[0029] In some implementations, as option 2 illustrated in FIG. 2B, all primary UEs served by the same or different base stations, belonging to the primary operator, may transmit a sensing signal using the serving beam on the overlapped time and frequency resource. In one example, the sensing signal may be the same for all primary UEs. In one example, the sensing signal may be distinguishable for all primary UEs. Each sensing signal may be orthogonal in time, frequency, sequence format, and / or code. That may help the secondary network node (e.g., network node 130) to recognize which UE the sensing signal is from. The sensing signal may be a dedicated signal (e.g., Physical Random Access Channel (PRACH) -like signal) . The dedicated signal may have larger signaling overhead. In one example, as option 2 illustrated in FIG. 2B, each primary UE may transmit the sensing signal separately during the sensing window. Network node 130 may perform beam-based sensing multiple times (e.g., perform twice in FIG. 2B) during the sensing window for all UEs according to the sensing signal configuration. In one example, network node 130 may determine that the beam of network node 130 is usable in an event that a Reference Signal Received Power (RSRP) measurement result of a received sensing signal for the beam is below an RSRP threshold. Notably, the received sensing signal may be independent for each primary UE.
[0030] In some implementations, UE 110 may determine whether to transmit the sensing signal. In one example, UE 110 may transmit the sensing signal in an event that UE 110 is in a connected mode. In one example, UE 110 may transmit the sensing signal in an event that UE 110 is in a connected mode and there is downlink or uplink data transmission. In some implementations, UE 110 may determine the transmission power of the sensing signal. In one example, UE 110 may use fixed uplink transmission power for the sensing signal in an event that network node 120 and network node 130 are non-collocated. In one example, UE 110 may determine uplink transmission power for the sensing signal based on the distance between network node 120 and network node 130 in an event that network node 120 and network node 130 are co-located. UE 110 may determine the distance based on the Sounding Reference Signal (SRS) power.
[0031] FIG. 2C is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. The present disclosure discloses several designs for dynamically on-off switching of the secondary channel or carrier (i.e., non-anchor carrier of Scell) . In one example, as illustrated in FIG. 2C, the periodicity of the sensing window may be a summation of the length of the sensing window, the length of the spectrum sharing window, gap X, and gap Y. UE 110 may deactivate the secondary channel or carrier (i.e., non-anchor carrier of Scell) in an event that UE 110 is not operating within the spectrum sharing window. UE 110 may communicate with network node 130 on the secondary channel or carrier (i.e., non-anchor carrier of Scell) during the spectrum sharing window in an event that the secondary channel or carrier is activated.
[0032] In some implementations, network node 120 may configure an Scell dormancy / non-dormancy indication to control the activation of the secondary channel or carrier (i.e., non-anchor carrier of Scell) . The network node 120 may configure the Scell dormancy / non-dormancy indication via an L1 signaling (e.g., Downlink Control Information (DCI) , two-stage DCI, etc. ) . UE 110 may receive the Scell dormancy / non-dormancy indication from a primary carrier of network node 120 (i.e., anchor carrier of Pcell) via a higher-layer signaling (e.g., SIB, UE-specific RRC signaling, etc. ) or an L1 signaling. In one example, UE 110 may transmit or receive signals on the secondary channel or carrier (i.e., the secondary channel or carrier is activated) during the spectrum sharing window in an event that the dormancy / non-dormancy indication indicates that the secondary carrier is in non-dormancy. In this case, UE 110 may be configured or scheduled with two physical sharing channels for two carriers (i.e., anchor carrier of Pcell, and non-anchor carrier of Scell) . In one example, UE 110 may not transmit or receive signals on the secondary channel or carrier (i.e., the secondary channel or carrier is deactivated) in an event that the indication dormancy / non-dormancy indicates that the secondary carrier is in dormancy. In some implementations, the network node 120 may further configure an active time indication in the activation information that indicates an active time of the secondary carrier and / or the duration of the active time of the secondary carrier. In some implementations, UE 110 may determine that dummy Channel State Information (CSI) reporting or no CSI on the secondary carrier in an event that the secondary carrier is in the dormancy.
[0033] In some implementations, the activation information may include an Scell activation command and an active time indication that indicates an active time of the secondary carrier (secondary channel) and / or the duration of the active time of the secondary carrier (secondary channel) . Network node 120 may configure the Scell activation command to activate or deactivate the secondary channel or carrier (i.e., non-anchor carrier of Scell) . UE 110 may receive the SCell activation command from a primary carrier of network node 120 (i.e., anchor carrier of Pcell) via a higher-layer signaling (e.g., SIB, UE-specific RRC signaling, etc. ) or an L1 signaling. UE 110 may activate or deactivate the secondary channel or carrier during the spectrum sharing window based on the Scell activation command. In one example, UE 110 may transmit or receive signals on the secondary channel or carrier (i.e., the secondary channel or carrier is activated) during the spectrum sharing window in an event that the Scell activation command activates the secondary channel or carrier. In this case, UE 110 may be configured or scheduled with two physical sharing channels for two carriers (i.e., anchor carrier of Pcell and non-anchor carrier of Scell) .
[0034] In some implementations, the activation information may include a Bandwidth Part (BWP) configuration that indicates the active BWP, and an active time indication that indicates an active time of the secondary carrier (secondary channel) and / or the duration of the active time of the secondary carrier (secondary channel) . UE 110 may receive the BWP configuration and the active time indication from a primary carrier of network node 120 (i.e., anchor carrier of Pcell) via higher-layer signaling (e.g., SIB, UE-specific RRC signaling, etc. ) or L1 signaling. UE 110 may activate the secondary channel or carrier (i.e., non-anchor carrier of Scell) during the spectrum sharing window in an event that the secondary channel or carrier is within the active BWP (i.e., the active BWP includes the secondary channel or carrier) . In this case, UE 110 may be configured or scheduled with one or two physical sharing channels for two carriers based on the channel characteristics.
[0035] In some implementations, network node 120 may configure an indication in Downlink Control Information (DCI) or two-stage DCI or an indication in Medium Access Control (MAC) Control Element (CE) to control the activation of the secondary channel or carrier. In this case, the activation information may include the indication and / or the active time indication in the DCI, the two-stage DCI, or the MAC CE indicating data scheduling on the secondary carrier. In some implementations, network node 120 may further configure an active time indication that indicates an active time of the secondary carrier (secondary channel) and / or the duration of the active time of the secondary carrier (secondary channel) . In some implementations, network node 130 may configure both indications in the DCI, the two-stage DCI, and / or the MAC CE. UE 110 may receive the indication and the active time indication from a primary carrier of network node 120 (i.e., anchor carrier of Pcell) via an L1 signaling. In one example, UE 110 may determine that the secondary carrier is activated during the spectrum sharing window in an event that the indication indicates there is data scheduling on the secondary carrier. In one example, UE 110 may enter a sleep mode (e.g., power saving mode or micro-sleep mode) on the secondary carrier during the spectrum sharing window in an event that the indication indicates there is no data scheduling on the secondary channel or carrier (i.e., the secondary channel or carrier is not available) . In this case, UE 110 may enter micro-sleep on the secondary channel for power saving in the baseband processing (e.g., UE 110 may not need to monitor DCI in the micro-sleep) .

Illustrative Processes
[0042] FIG. 4 illustrates an example process 400 in accordance with an implementation of the present disclosure. Process 400 may be an example implementation of above scenarios / schemes, whether partially or completely, with respect to spectrum sharing of the present disclosure. Process 400 may represent an aspect of implementation of features of communication apparatus 310. Process 400 may include one or more operations, actions, or functions as illustrated by one or more of blocks 410 to 420. Although illustrated as discrete blocks, various blocks of process 400 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks of process 400 may be executed in the order shown in FIG. 4 or, alternatively, in a different order. Process 400 may be implemented by communication apparatus 310 or any suitable UE or machine type devices. Solely for illustrative purposes and without limitation, process 400 is described below in the context of communication apparatus 310. Process 400 may begin at block 410.
