[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. As shown in FIG.

[0021] Typically, the number of terminals 10 is multiple, and one or more terminals 10 may be distributed in a cell managed by each network device 20.

[0026] FIG. 2 is a flowchart of an information reporting method provided by an exemplary embodiment of the present application, illustratively applicable to the terminal and network device shown in FIG. 1, and the method includes at least a part 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, where each access network device 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 at least one resource according to the channel state information.

[0029] Here, the terminal performs measurement based on a CSI-RS (Channel State Information-Reference Signal) and / or an 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; and 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] In addition, 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 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, the 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, a first resource corresponding to a first resource subset and a second resource corresponding 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 CSI-RS, SSB, 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 the antenna port as an example for description, in other embodiments, the antenna port and the CSI-RS port or the CSI-RS antenna port 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 a new embodiment, and the steps performed by the network device can be implemented separately to form a new embodiment.

[0043] An embodiment of the present application provides an information reporting method, in which 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 the channel state information takes into account at least one access network device simultaneously, thereby overcoming the limitation of the reported channel state information by the access network device and improving 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 ports of the 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 disposed 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 manners.

[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 each access network device as corresponding to 1 bit as an example, in other embodiments, each access network device may correspond to 2 bits, 3 bits or other numbers, which is not limited in this application.

[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 enables a network device to determine which access network device will serve a terminal by indicating the selected access network device using channel state information, 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 a combination identifier, the combination identifier indicates a beam combination, the beam combination including at least one beam.

[0057] Here, the antenna ports corresponding to each beam of the at least one beam are selected from the antenna ports of the at least one access network device.

[0058] In the embodiment of the present application, at least one beam is indicated by one combination identifier included in the channel state information, and the antenna port corresponding to each beam among the at least one beam is not limited to the antenna port of one access network device or the antenna port of multiple access network devices. That is, when the channel state information includes one combination identifier, the beam is reported in a unified manner without distinction according to the access network device to which the antenna port corresponding to the beam belongs.

[0059] In some embodiments, the combination identifier has a correspondence relationship with an antenna port, and at least one beam indicated by the combination identifier included in the channel state information can indicate an 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 a first dimension, N2 is the number of antenna ports in a 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, when 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 certain beam is from one access network device or multiple access network devices, the terminal can select N1*N2+N 11 *N 22 It is necessary to instruct 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 antenna ports corresponding to beams included in a beam combination indicated by the first type combination identifier are selected from antenna ports of one access network device, and antenna ports corresponding to beams included in a beam combination indicated by the second type combination identifier are selected from antenna ports of the multiple access network devices.

[0065] In the embodiment of the present application, at least one beam is indicated by a plurality of combination identifiers included in the channel state information, and the antenna port corresponding to the beam may be selected from the antenna port of one access network device or from the antenna port of multiple access network devices, so the combination identifier is divided into two types, and the antenna port corresponding to the beam included in the beam combination indicated by the first type of combination identifier is selected from the antenna port of one access network device, and the antenna port corresponding to the beam included in the beam combination indicated by the second type of combination identifier is selected from the antenna port of multiple access network devices, thereby distinguishing whether the antenna port corresponding to the beam belongs to one access network device or multiple access network devices according to the different types of combination identifier. That is, when the channel state information includes a plurality of combination identifiers, the report is made according to the access network device to which the antenna port corresponding to the beam belongs.

[0066] In some embodiments, the combination identifier has a correspondence relationship with an antenna port, and at least one beam indicated by the combination identifier included in the channel state information can indicate an 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 a first dimension, N2 is the number of antenna ports in a 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 sent 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 L1 beams belong only to the antenna ports of the first access network device, the second combination identifier indicates that the antenna ports of 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 L3 beams include antenna ports belonging to both the first and second access network devices, and L1+L2+L3=L. For the first combination identifier, the terminal only needs to indicate which L1 beams to select from among N1*N2 beams, and for the second combination identifier, the terminal only needs to indicate which L1 beams to select from among 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 of N1*N2+N 11 *N 22 It is necessary to instruct 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 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 are reported in one beam, thereby improving the transmission performance; and different types of combination identifiers can distinguish the access network device to which the antenna port corresponding to the beam belongs, thereby improving the transmission efficiency.

[0070] In some embodiments, the channel state information further indicates an access network device identifier of the access network device corresponding to the first type combination identifier and / or the second type combination identifier, respectively.

[0071] In the embodiment of the present application, the channel state information not only distinguishes the 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 by the channel state information. It may be understood 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 combination between the embodiments.
