The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment.
[0048] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.
[0049] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.
[0050] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.
[0051] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. In some embodiments of the present application, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network device may also be a base station set up in a location such as land or water.
[0052] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.
[0053] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or also referred to as a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices located within the coverage area.
[0054] Figure 1A exemplarily shows a network device and two terminal devices. In some embodiments of the present application, the communication system 100 may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.
[0055] For example, FIG1B is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1B , a terminal device 1101 and a satellite 1102 are included, and wireless communication can be performed between the terminal device 1101 and the satellite 1102. The network formed between the terminal device 1101 and the satellite 1102 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1B , the satellite 1102 can have the function of a base station, and the terminal device 1101 and the satellite 1102 can communicate directly. In the system architecture, the satellite 1102 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.
[0056] For example, FIG1C is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1C , it includes a terminal device 1201, a satellite 1202, and a base station 1203. Wireless communication can be performed between the terminal device 1201 and the satellite 1202, and communication can be performed between the satellite 1202 and the base station 1203. The network formed between the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1C , the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 1203 may be included in the communication system, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.
[0057] It should be noted that Figures 1A-1C are only examples of the system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems, such as 5G communication systems, LTE communication systems, etc., and the embodiment of this application does not make specific limitations on this.
[0058] In some embodiments of the present application, the wireless communication system shown in Figures 1A-1C may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but the embodiments of the present application are not limited to this.
[0059] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1A as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.
[0060] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.
[0061] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.
[0062] The “configuration” in the embodiment of the present application may include configuration through at least one of system messages, radio resource control (RRC) signaling and media access control element (MAC CE).
[0063] In some embodiments of the present application, "predefined" or "preset" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). This application does not limit the specific implementation method. For example, predefined may refer to information defined in a protocol.
[0064] In some embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.
[0065] In satellite communications, satellites may have limited transmission power and processing bandwidth, depending on their deployment and the NTN system's requirements for the physical channel signal-to-noise ratio (SNR) of terminal devices. Consequently, a satellite may only be able to serve a portion of its coverage area at a time. In other words, due to limited power and feeder link bandwidth, a satellite may not be able to keep all beams active at the same time and ensure that each beam meets the nominal equivalent isotropic radiated power (EIRP) density. Consequently, related technologies have proposed the use of beam hopping in the downlink.
[0066] Figure 2 gives an example of the beam hopping implementation process. Referring to Figure 2, the satellite serves a group of beams at time t0 (i.e., beam 1, beam 2, and beam 3 in Figure 2, and each beam in the group of beams can be called an active beam or an active satellite beam). The coverage area of each beam in the group of beams on the earth can be regarded as a cell. Therefore, multiple active beams can correspond to multiple active cells. Then, at time t1, the group of beams will become inactive, and at this time, the satellite can activate another group of beams (i.e., beam 1', beam 2', and beam 3' in Figure 2). The above process is the beam hopping process in the multi-beam system. As can be seen from the above description, the beam hopping process will cause the cell to switch from an active state to an inactive state.
[0067] It should be understood that FIG2 is merely an example of a satellite communication system, and that the embodiments of the present application can be applied to any type of communication system that supports beam hopping technology. For example, a cell contains multiple beams or multiple groups of beams. These multiple beams or multiple groups of beams alternate between an active state and an inactive state. In this case, the cell may always be in an active state, but some or all beams within the cell may switch between an active state and an inactive state. The above process can also be understood as a beam hopping process.
[0068] The introduction of beam hopping technology will affect the random access process of the terminal device, which is not considered in the related art, and may increase the probability of failure of the random access process. In response to the above problem, the embodiments of the present application are described in detail below.
[0069] Figure 3 is a schematic flowchart of a method for wireless communication provided in an embodiment of the present application. The method in Figure 3 can be applied to a wireless communication system that supports beam hopping technology, such as an NTN system. The NTN system can be, for example, a satellite communication system. The method in Figure 3 can be performed by a terminal device. The terminal device can be any of the types of terminal devices mentioned above. For example, the terminal device can support NTN functionality or satellite communication functionality.
[0070] 3 , in step S310 , the terminal device performs a first operation according to first information.
[0071] In some implementations, the first information may be associated with an activation period / inactivation period of the first cell.
[0072] In some implementations, the first information is associated with activation / deactivation status of one or more beams (or beam directions) within the first cell.
[0073] In some implementations, the first operation is associated with random access of the first cell.
[0074] In some implementations, the first cell may be the cell where the terminal device is currently located. Alternatively, the first cell may be the serving cell of the terminal device.
[0075] In some implementations, the first information may be used to indicate or determine a period or pattern of turning on / off the first cell. As mentioned above, in a beam hopping system, a beam sent by a network device (such as a satellite) may correspond to a cell. Taking the example of beam 1 of a network device corresponding to cell 1 and beam 2 corresponding to cell 2, when the network device switches the active beam from beam 1 to beam 2, it is equivalent to the network device turning off cell 1 and turning on cell 2. From the perspective of a terminal device, if the terminal device is within the coverage of cell 1 (i.e., cell 1 is the serving cell of the terminal device), the terminal device will observe that the serving cell 1 changes from an open state to a closed state. After a period of time, the terminal device will observe that the serving cell 1 changes from a closed state to an open state again. The off period of a cell may also be referred to as the non-active period of the cell. The on period of a cell may also be referred to as the active period of the cell. Figure 4 shows an example of an active period / non-active period pattern of a cell. As can be seen from Figure 4, the cell alternately enters an active period and a non-active period.
[0076] The inactive period of the cell mentioned in the embodiments of the present application can be replaced by the inactive period of one or some beams within the cell, or the time interval between the inactive states of one or some beams within the cell.
[0077] The activation period of the cell mentioned in the embodiments of the present application can be replaced by the activation period of one or some beams within the cell, or the time interval between the activation states of one or some beams within the cell.
[0078] It should be understood that the beams mentioned in the embodiments of the present application may also be referred to as spatial transmission filters. The beams may be associated with a resource index of a reference signal. The reference signal may be, for example, a downlink reference signal. For example, the beams may be associated with a channel state information reference signal (CSI-RS) resource index. In another example, the beams may be associated with a synchronization signal block (SSB) index.
[0079] In some implementations, as shown in FIG5 , the first information may be sent by the network device to the terminal device.
[0080] In some implementations, the first information may be carried in system information sent by the network device.
[0081] In some implementations, the first information can be used to indicate or determine one or more of the following: the duration of the activation period of the terminal device, the remaining duration of the activation period, the start time of the activation period, the end time of the activation period, the cycle of the activation period, the start time of the next activation period after the current activation period, etc.
[0082] Example 1: The first operation includes starting a first timer
[0083] The first timer mentioned in the first embodiment may be associated with a first message, and the first message may be a message sent by a terminal device for random access.
[0084] In some implementations, the first message is a message 1 (Msg1) for random access, and the first timer associated with the first message is a random access response (RAR) timer. For example, the first message may be a random access message. Alternatively, the first message may be used to transmit a physical random access channel (PRACH). In this implementation, the duration of the first timer may be referred to as a random access response window (RAR window).
[0085] In some implementations, the first message is a message A (MsgA) for random access, and the first timer associated with the first message is a random access response timer. In this implementation, the timing duration of the first timer can be called a random access response window.
[0086] In some implementations, the first message is Message 3 (Msg3) for random access, and the first timer associated with the first message is a contention resolution timer. Alternatively, the first message may be used to transmit a Message 3 physical uplink shared channel (Msg3PUSCH). In this implementation, the duration of the first timer may be referred to as a contention resolution window.
[0087] In some implementations, the start time of the first timer is determined based on one or more of the following: a first moment, determined based on the transmission time of the first message; a second moment, determined based on the end moment of the first activation period of the first cell, wherein the first activation period corresponds to the sending time of the first message; a first time period, determined based on the round-trip time from the terminal device to the network device; and a second time period, determined based on the timing duration of the first timer.
[0088] In some implementations, the aforementioned step S310 may be replaced by: the terminal device determines the start time of the first timer based on one or more of the first time, the second time, the first time period, and the second time period.
[0089] In some implementations, the first moment may be determined based on a start moment or an end moment of a transmission time of the first message. For example, the first moment may be a start moment or an end moment of a transmission time of the first message.
[0090] In some implementations, the first message is Message 1 or Message A, and the first message is transmitted on a random access opportunity (RACH occasion, RO). The first moment can be determined based on the start moment or end moment of the RO. For example, the first moment can be the start moment or end moment of the RO.
[0091] In some implementations, determining the second time based on the end time of the first activation period of the first cell includes: the second time being the end time of the first activation period of the first cell. Alternatively, determining the second time based on the end time of the first activation period of the first cell includes: the second time being equal to the end time of the first activation period plus an offset value.
[0092] In some implementations, the first activation period of the first cell corresponds to the sending time of the first message, including: the sending time of the first message falls within the first activation period of the first cell. That is, the terminal device sends the first message during the first activation period of the first cell.
[0093] In some implementations, the first period is determined based on a round trip time (RTT) from the terminal device to the network device, including: the first period is equal to the round trip time from the terminal device to the network device. The round trip time can be based on a timing advance of the terminal device and / or T mac OK. mac Alternatively, the first time period is determined based on the round-trip time from the terminal device to the network device, and includes: the first time period is equal to the sum of the round-trip time from the terminal device to the network device and the offset value.
[0094] In some implementations, determining the second period based on the timing duration of the first timer includes: the second period is equal to the timing duration of the first timer. Alternatively, determining the second period based on the timing duration of the first timer includes: the second period is equal to the sum of the timing duration of the first timer and an offset value.
[0095] In some implementations, if the third time is earlier than or equal to the second time, the first timer is started at the third time; and / or if the third time is later than the second time, the first timer is started during the second activation period (e.g., the start time of the second activation period). The third time is the time corresponding to the sum of the first time and the first period. In other words, the third time is the time obtained by deducting the first time from the first time.
[0096] 6A to 6B show an example of a method for determining the start time of the RAR timer (corresponding to the first timer mentioned above). Referring to FIG. 6A to FIG. 6B , the terminal device selects an RO for transmitting PRACH during the first activation period of the cell. The terminal device then transmits PRACH on the RO (the transmission of the PRACH corresponds to the transmission of the first message mentioned above). After the PRACH transmission ends, the end time of the PRACH transmission can be set to t0 (corresponding to the first time mentioned above). The terminal device can then set a time period T (corresponding to the first time period mentioned above) based on t0, and the time period T can be the RTT from the terminal device to the network device in the NTN system. Next, the terminal device can determine the relationship between t0+T (corresponding to the third time period mentioned above) and the end time of the first activation period (corresponding to the second time period mentioned above). For example, as shown in FIG. 6A , if t0+T is before the end time of the first activation period, the terminal device starts the RAR timer. For example, as shown in Figure 6B, if t0+T is after the end time of the first activation period (i.e., t0+T is in the non-activation period of the cell), the terminal device can start the RAR timer in the second activation period (i.e., the next activation period of the first activation period).
[0097] In some implementations, if the fourth moment is earlier than or equal to the second moment, the first timer is started at the third moment; and / or, if the fourth moment is later than the second moment, the first timer is started at the start moment of the second activation period; wherein the third moment is the moment corresponding to the sum of the first moment and the first time period (or, the third moment is the moment obtained by pushing the first time period back on the basis of the first moment), the fourth moment is the moment corresponding to the sum of the first time period and the second time period (or, the fourth moment is the moment obtained by pushing the first time period back on the basis of the first moment), and the second activation period is the next activation period of the first activation period.
[0098] Figures 7A to 7B show an example of a method for determining the start time of the RAR timer (corresponding to the first timer mentioned above). Referring to Figures 7A to 7B, the terminal device selects an RO for transmitting PRACH during the first activation period of the cell. Then, the terminal device transmits PRACH on the RO (the transmission of the PRACH corresponds to the transmission of the first message mentioned above). After the PRACH transmission is completed, the end time of the PRACH transmission can be set to t0 (corresponding to the first moment mentioned above). Then, the terminal device can set T1 (corresponding to the first time period mentioned above) and T2 (corresponding to the second time period mentioned above) based on t0. T1 can be equal to the RTT from the terminal device to the network device in the NTN system, and T2 can be equal to the timing duration of the RAR timer (i.e., the duration corresponding to the RAR window). Then, the terminal device can determine the relationship between t0+T1+T2 (corresponding to the fourth moment mentioned above) and the end time of the first activation period (corresponding to the second moment mentioned above). For example, as shown in FIG7A , if t0+T1+T2 is before the end time of the first activation period, the terminal device starts the RAR timer at t0+T1 (corresponding to the third time in the above text). For another example, as shown in FIG7B , if t0+T1+T2 is after the end time of the first activation period (i.e., t0+T1+T2 is in the inactive period of the cell), the terminal device may start the RAR timer in the second activation period (i.e., the next activation period after the first activation period).
[0099] In some implementations, step S310 may include or be replaced by: if the terminal device sends a first message during the first non-activation period of the first cell, the terminal device starts a first timer at the start time of the next activation period of the first non-activation period; wherein the first message is a message for random access, and the first timer is associated with the first message.
[0100] FIG8 illustrates an example of how the start time of the first timer is determined. Referring to FIG8 , a terminal device transmits a PRACH message during a first inactive period of a cell (corresponding to the transmission of the first message described above). In this case, the terminal device may start the RAR timer (corresponding to the first timer described above) during the next active period following the first inactive period.
[0101] Embodiment 2: The first operation includes pausing the first timer
[0102] In embodiment 2, step S310 may include or be replaced by: if the first timer runs to the first non-activation period of the first cell, the terminal device suspends the first timer; wherein the first timer is associated with the first message, and the first message is a message sent by the terminal device for random access.
[0103] Furthermore, in some implementations, the terminal device may continue to run the first timer at the start time of the next activation period of the first inactive period.
[0104] Referring to Figure 9, the terminal device selects an RO for transmitting PRACH during the first activation period of the cell. Then, the terminal device transmits PRACH on the RO (the transmission of the PRACH corresponds to the transmission of the first message in the previous text). After the PRACH transmission is completed, the end time of the PRACH transmission can be set to t0 (corresponding to the first time mentioned above). Then, the terminal device can set T based on t0, and T can be equal to the RTT from the terminal device to the network device in the NTN system. Then, the terminal device can start the RAR timer after t0+T (corresponding to the first timer in the previous text). If the RAR timer runs to the inactive period of the cell, the RAR timer can be suspended at this time. When the start time of the next activation period of the cell arrives, the terminal device can continue to run (resume) the RAR timer.
[0105] Embodiment 3: The first operation includes determining whether the first random access opportunity in the first activation period of the first cell is valid
[0106] In some implementations, whether the first random access opportunity is valid is determined based on one or more of the following: a first moment, determined based on the time corresponding to the first random access opportunity (or the first RO); a second moment, determined based on the end time of the first activation period; a first time period, determined based on the round-trip time from the terminal device to the network device; a second time period, determined based on the timing duration of the first timer; wherein the first timer is associated with the message used to transmit the first random access opportunity.
[0107] In some implementations, the aforementioned step S310 may be replaced by: the terminal device determines whether the first random access opportunity within the first activation period of the first cell is valid based on one or more of the first moment, the second moment, the first time period, and the second time period.
[0108] In some implementations, the first moment may be determined based on the start moment or the end moment of the first random access opportunity. For example, the first moment may be the start moment or the end moment of the first random access opportunity. Alternatively, the first moment may be the moment corresponding to the start moment or the end moment of the first random access opportunity plus an offset value.
[0109] In some implementations, determining the second time based on the end time of the first activation period of the first cell includes: the second time being the end time of the first activation period of the first cell. Alternatively, determining the second time based on the end time of the first activation period of the first cell includes: the second time being equal to the end time of the first activation period plus an offset value.
[0110] In some implementations, determining the first period based on a round trip time from the terminal device to the network device includes: the first period being equal to the round trip time from the terminal device to the network device. The round trip time may be based on a timing advance of the terminal device and / or T mac OK. mac Alternatively, the first time period is determined based on the round-trip time from the terminal device to the network device, and includes: the first time period is equal to the sum of the round-trip time from the terminal device to the network device and the offset value.
[0111] In some implementations, determining the second period based on the timing duration of the first timer includes: the second period is equal to the timing duration of the first timer. Alternatively, determining the second period based on the timing duration of the first timer includes: the second period is equal to the sum of the timing duration of the first timer and an offset value. The first timer mentioned herein may be associated with a message transmitted during the first random access opportunity. For example, if the first random access opportunity is used to transmit a random access message (or PRACH), the first timer may be a RAR timer associated with the random access message.
[0112] In some implementations, if the third time is earlier than or equal to the second time, the first random access opportunity is valid; and / or if the third time is later than the second time, the first random access opportunity is invalid. The third time is the time corresponding to the sum of the first time and the first period. In other words, the third time is the time obtained by deducting the first period from the first time.
[0113] Referring to Figure 10, the terminal device determines that there is an RO within the first activation period of the first cell (corresponding to the first random access opportunity mentioned above) based on the configuration information of the network device. The terminal device can determine the end time of the RO as t0 (corresponding to the first moment mentioned above). Then, the terminal device can determine the relationship between t0+T (corresponding to the third moment mentioned above, T can represent RTT) and the end time of the first activation period (corresponding to the second moment mentioned above). If t0+T exceeds the end time of the first activation period, the terminal device determines that the RO is an invalid RO. If t0+T does not exceed the end time of the first activation period, the terminal device determines that the RO is a valid RO.
[0114] In some implementations, if the fourth time is earlier than or equal to the second time, the first random access opportunity is valid; and / or if the fourth time is later than the second time, the first random access opportunity is invalid. The fourth time is the time corresponding to the sum of the first time and the first time period and the second time period. In other words, the fourth time is the time obtained by deducting the first time period and the second time period from the first time period.
[0115] Referring to Figure 11, the terminal device determines that there is an RO in the first activation period of the first cell based on the configuration information of the network device (corresponding to the first random access opportunity in the previous text). The terminal device can determine the end time of the RO as t0 (corresponding to the first moment in the previous text). Then, the terminal device can determine the relationship between t0+T1+T2 (corresponding to the fourth moment in the previous text, T1 can represent RTT, and T1 corresponds to the first time period mentioned in the previous text, T2 represents the timing duration of the RAR timer, that is, the duration corresponding to the random access response window, and T2 corresponds to the second time period mentioned in the previous text) and the end time of the first activation period (corresponding to the second moment in the previous text). If t0+T1+T2 exceeds the end time of the first activation period, the terminal device determines that the RO is an invalid RO. If t0+T1+T2 does not exceed the end time of the first activation period, the terminal device determines that the RO is a valid RO.
[0116] In some implementations, if the first random access opportunity is valid, the terminal device may send a random access message through the first random access opportunity.
[0117] In some implementations, if the first random access opportunity is invalid, the terminal device does not send a random access message through the first random access opportunity.
