[0019] The application scenario of the present invention will be described below.
[0020] FIG. 1 is a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include a terminal 10, a network device 20, and an access network device 30.
[0021] Typically, there are multiple terminals 10, and one or more terminals 10 may be distributed within a cell managed by each network device 20. The terminals 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices or other processing devices connected to wireless modems, and various types of user equipment (UE), mobile stations (MS), etc., all of which have wireless communication capabilities. For convenience of explanation, in the embodiments of the present application, the above devices are collectively referred to as terminals.
[0022] The network device 20 is a device disposed in an access network to provide a wireless communication function to the terminal 10. For convenience of explanation, in the embodiments of the present application, the above devices that provide a wireless communication function to the terminal 10 are collectively referred to as network devices. A connection is established between the network device 20 and the terminal 10 over an air interface, and communication can be performed via the connection, including signaling and data exchange. There may be multiple network devices 20, and two adjacent network devices 20 may communicate with each other via wired or wireless communication. The terminal 10 can switch between different network devices 20, i.e., can establish a connection with different network devices 20.
[0023] The network device 20 may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different radio access technologies, the name of a device having a network device function may be different. For example, in a 5G NR system, it is called a gNodeB or gNB. As communication technologies develop, the name of the "network device" may change.
[0024] The network device 20 includes at least one access network device 30, which provides communication functions to the terminal 10; i.e., the network device 20 extends its coverage by deploying access network devices 30, facilitating access by more terminals 10 to the network device 20.
[0025] In some embodiments, the access network device 30 is a TRP (Transmission Reception Point) device, or a TP (Transmission Point), or an RRH (Remote Radio Header), or a panel (antenna panel).
[0026] FIG. 2 is a flowchart of an information reporting method provided by an exemplary embodiment of the present application, which is illustratively applicable to the terminal and network device shown in FIG. 1, and the method includes at least some of the following contents:
[0027] In step 201, a terminal transmits channel state information to a network device, where the channel state information indicates at least one of at least one beam selected based on at least one resource for performing channel measurements and an antenna port of the at least one access network device corresponding to each beam of the at least one beam.
[0028] In an embodiment of the present application, a network device provides services to a terminal by configuring at least one access network device, each of which is configured with multiple antenna ports, and the terminal can indicate a beam selected based on at least one resource according to channel state information transmitted to the network device, and the terminal can also indicate an antenna port of the at least one access network device corresponding to each beam of the at least one beam selected based on the at least one resource according to the channel state information.
[0029] Here, the terminal performs measurements based on CSI-RS (Channel State Information-Reference Signal) and / or SSB (Synchronization Signal and PBCH Block) transmitted from the network device to obtain channel state information measured based on at least one resource, and indicates at least one selected beam based on the channel state information. The terminal can also indicate an antenna port of at least one access network device corresponding to each beam of the at least one beam based on the channel state information.
[0030] Furthermore, since the present application relates to at least one access network device, the terminal can directly select an antenna port of the at least one access network device, facilitate the aggregation of the antenna ports of the at least one access network device, and unify the reporting based on the transmitted channel state information.
[0031] In some embodiments, the resource is called a Channel Measurement Resource (CMR).
[0032] In step 202, the network device receives channel state information transmitted from the terminal.
[0033] In an embodiment of the present application, the network device can determine the beam selected by the terminal based on the received channel state information, or can also determine the antenna port of at least one access network device corresponding to each beam among the at least one beam selected by the terminal, thereby ensuring that the network device knows the beam selected by the terminal.
[0034] In some embodiments, at least one resource corresponds to a different resource subset or a different resource set.
[0035] In some embodiments, different resource subsets or different resource sets correspond to different control resource set pool indices, or different TRPs, or different TPs, or different RRHs.
[0036] In an embodiment of the present application, a resource subset or a resource set includes multiple resources, and at least one resource in an embodiment of the present application belongs to a different resource subset or a different resource set.
[0037] For example, the at least one resource includes two resources, where the first resource corresponds to a first resource subset and the second resource corresponds to a second resource subset.
[0038] Optionally, different resource sets or different resource sets correspond to different control resource set pool indexes, or different TRPs, or different TPs, or different RRHs.
[0039] Optionally, the at least one resource includes at least one of a CSI-RS, an SSB, an SRS (Sounding Reference Signal), and so on.
[0040] In some embodiments, each access network device has an access network device identifier, and the access network device identifier corresponding to each access network device is indicated by at least one of a resource index, a resource subset index, a resource set index, a control resource set pool index, an antenna port index, a TRP index, a TP index, an RRH index, or a panel index.
[0041] It should be noted that the embodiments of the present application only take antenna ports as an example, and in other embodiments, antenna ports and CSI-RS ports or CSI-RS antenna ports can be equivalently replaced, and are not limited to the embodiments of the present application.
[0042] It should be noted that the steps performed by the terminal in the embodiments of the present application can be implemented separately to form new embodiments, and the steps performed by the network device can be implemented separately to form new embodiments.
[0043] An embodiment of the present application provides an information reporting method, in which the channel state information reported by a terminal to a network device can indicate at least one of at least one selected beam and an antenna port of at least one access network device corresponding to each beam of the at least one beam, and since the channel state information takes into account at least one access network device simultaneously, the reported channel state information overcomes the limitation of the access network device and improves transmission performance.
[0044] Optionally, based on the embodiment shown in FIG. 2, the channel state information not only indicates the selected beam and the antenna port of at least one access network device corresponding to each beam among the selected beams, but also indicates the selected at least one access network device.
[0045] In an embodiment of the present application, a plurality of access network devices are arranged in the network device, and the channel state information sent by the terminal to the network device after measuring the channel can indicate at least one selected access network device.
[0046] Here, for a plurality of access network devices disposed in a network device, the terminal can select at least one access network device among the plurality of access network devices, and report the selected at least one access network device and corresponding channel state information via the channel state information.
[0047] In some embodiments, the channel state information includes a first bit, which indicates whether to select an access network device, and the first bit may be preset or set in other ways.
[0048] For example, in the embodiment of the present application, each access network device corresponds to a bit or code point, and the bit or code point indicates whether the access network device is selected or not.
[0049] Optionally, each access network device corresponds to one bit, and the one bit indicates whether the access network device is selected. For example, when the bit corresponding to an access network device is 0, it indicates that the access network device is not selected, and when the bit corresponding to an access network device is 1, it indicates that the access network device is selected. Or, when the bit corresponding to an access network device is 0, it indicates that the access network device is selected, and when the bit corresponding to an access network device is 1, it indicates that the access network device is not selected.
[0050] It should be noted that this application only describes, as an example, that each access network device corresponds to one bit, but in other embodiments, each access network device may correspond to two bits, three bits, or other numbers, and this application is not limited thereto.
[0051] For example, if the network device has four access network devices, the channel state information includes four bits, each bit indicating whether one access network device is selected. For these four access network devices, there are a total of 15 cases for selecting an access network device.
[0052] The method provided by the embodiments of the present application uses channel state information to indicate the selected access network device, thereby enabling the network device to determine which access network device will serve the terminal, thereby not only improving the immediacy of information transmission but also improving transmission performance.
[0053] Based on the embodiment shown in FIG. 2, each beam corresponds to an antenna port of at least one access network device.
[0054] In an embodiment of the present application, a terminal can select at least one beam from a plurality of beams, each beam corresponding to an antenna port of at least one access network device.
[0055] In some embodiments, one beam corresponds to an antenna port of one access network device, or one beam corresponds to antenna ports of multiple access network devices.
[0056] Optionally, the channel state information indicates one combination identifier, the one combination identifier indicates one beam combination, the beam combination including at least one beam.
[0057] Here, the antenna port corresponding to each beam of the at least one beam is selected from the antenna ports of the at least one access network device.
[0058] In the embodiment of the present application, one combination identifier included in the channel state information indicates at least one beam, and the antenna ports corresponding to each of the at least one beam are not limited to antenna ports of one access network device or antenna ports of multiple access network devices, that is, when the channel state information includes one combination identifier, the beams are reported uniformly without distinguishing between the access network devices to which the antenna ports corresponding to the beams belong.
[0059] In some embodiments, the combination identifier has a correspondence relationship with the antenna port, and at least one beam indicated by the combination identifier included in the channel state information can indicate the antenna port of the access network device corresponding to each beam according to the above correspondence relationship.
[0060] For example, the network device includes two access network devices, which are a first access network device and a second access network device, respectively, and the first access network device includes N1*N2 antenna ports, where N1 is the number of antenna ports in the first dimension, N2 is the number of antenna ports in the second dimension, and the second access network device includes N 11 *N 22 antenna ports, where N 11 is the number of antenna ports in the first dimension, and N 22 is the number of antenna ports in the second dimension, and the antenna ports corresponding to each beam are N1*N2 and N 11 *N 22 The antenna ports can be selected from:
[0061] Here, if the channel state information transmitted from the terminal indicates L beams, the antenna ports including L1 beams belong only to the antenna ports of the first access network device, the antenna ports of L2 beams belong only to the antenna ports of the second access network device, and the antenna ports including L3 beams may include antenna ports belonging to both the first and second access network devices, and L1+L2+L3=L. Since there is no distinction between whether a beam is from one access network device or multiple access network devices, the terminal may select N1*N2+N 11 *N 22 It is necessary to specify which L beams to select from the beams.
[0062] In an embodiment of the present application, at least one beam is indicated by a combination identifier included in the channel state information, and an antenna port corresponding to each beam is selected from the antenna ports of at least one access network device, so that the antenna ports of at least one access network device can be reported with one beam, thereby improving transmission performance.
[0063] Optionally, the channel state information indicates a plurality of combination identifiers, each combination identifier indicating one beam combination, each beam combination including at least one beam.
[0064] Here, the multiple combination identifiers include a first type combination identifier and a second type combination identifier, and the antenna ports corresponding to the beams included in the beam combination indicated by the first type combination identifier are selected from the antenna ports of one access network device, and the antenna ports corresponding to the beams included in the beam combination indicated by the second type combination identifier are selected from the antenna ports of the multiple access network devices.
[0065] In an embodiment of the present application, at least one beam is indicated by multiple combination identifiers included in the channel state information, and the antenna ports corresponding to the beams may be selected from the antenna ports of one access network device or from the antenna ports of multiple access network devices. Therefore, the combination identifiers are divided into two types: the antenna ports corresponding to the beams included in the beam combination indicated by the first type of combination identifier are selected from the antenna ports of one access network device, and the antenna ports corresponding to the beams included in the beam combination indicated by the second type of combination identifier are selected from the antenna ports of multiple access network devices. Thus, different types of combination identifiers distinguish whether the antenna ports corresponding to the beams belong to one access network device or multiple access network devices. That is, when the channel state information includes multiple combination identifiers, the reporting is performed according to the access network devices to which the antenna ports corresponding to the beams belong.
[0066] In some embodiments, the combination identifier has a correspondence relationship with the antenna port, and at least one beam indicated by the combination identifier included in the channel state information can indicate the antenna port of the access network device corresponding to each beam according to the above correspondence relationship.
[0067] For example, the network device includes two access network devices, which are a first access network device and a second access network device, respectively, and the first access network device includes N1*N2 antenna ports, where N1 is the number of antenna ports in the first dimension, N2 is the number of antenna ports in the second dimension, and the second access network device includes N 11 *N 22 antenna ports, where N 11 is the number of antenna ports in the first dimension, and N 22is the number of antenna ports in the second dimension, and the antenna ports corresponding to each beam are N1*N2 and N 11 *N 22 The antenna ports can be selected from among the antenna ports.
[0068] Here, the channel state information transmitted from the terminal indicates that there are L beams, and the channel state information includes three combination identifiers, where the first combination identifier indicates that the antenna ports of the L1 beams belong only to the antenna ports of the first access network device, the second combination identifier indicates that the antenna ports of the L2 beams belong only to the antenna ports of the second access network device, and the third combination identifier indicates that the antenna ports of the L3 beams include both the antenna ports belonging to the first access network device and the antenna ports belonging to the second access network device, and L1+L2+L3=L, then for the first combination identifier, the terminal only needs to indicate which L1 beams to select from among the N1*N2 beams, and for the second combination identifier, the terminal only needs to indicate which L1 beams to select from among the N1*N2 beams. 11 *N 22 For the third combination identifier, the terminal only needs to indicate which L2 beams to select from among the beams N1*N2+N 11 *N 22 It is necessary to specify which L3 beams to select from the beams.
[0069] In the embodiments of the present application, at least one beam is indicated by multiple types of combination identifiers included in the channel state information, and the antenna ports corresponding to each beam are selected from the antenna ports of at least one access network device, so that the antenna ports of at least one access network device are reported in one beam, improving transmission performance; and different types of combination identifiers can distinguish the access network devices to which the antenna ports corresponding to the beams belong, improving transmission efficiency.
[0070] In some embodiments, the channel state information further indicates access network device identifiers of the access network devices corresponding to the first type combination identifier and / or the second type combination identifier, respectively.
[0071] In the embodiments of the present application, the channel state information not only distinguishes beams of antenna ports belonging to different access network devices according to the type of combination identifier, but also indicates the access network device identifier of the access network device corresponding to each combination identifier according to the channel state information, which may be understood as meaning that the channel state information can indicate the access network device identifier of the access network device corresponding to the first type of combination identifier, and can also indicate the access network device identifier of the access network device corresponding to the second type of combination identifier.
[0072] The method provided by the embodiment of the present application indicates access network devices corresponding to different combination identifiers according to the channel state information, thereby improving the comprehensiveness of the reported channel state information.
[0073] It should be noted that the above embodiments may be divided into new embodiments or may be combined with other embodiments to form new embodiments, and the present application does not limit the combinations between the embodiments.
