[0069] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0070] In existing technologies, beamforming can be used to improve transmission performance at both the transmitting and receiving ends to combat high-frequency path loss. The transmitting and receiving ends obtain matched beam pairs through beam training. Taking downlink beam training as an example, the network side configures reference signals for beam training, and the terminal reports the indexes of reference signals with higher received power (L1-RSRP) or signal-to-interference-plus-noise ratio (L1-SINR) and their corresponding RSRP or SINR to the network side. The reference signals used for downlink beam training can be CSI-RS and / or SSB (Synchronization Signal Block), and both are reference signals of the serving cell.
[0071] The specific configuration method is as follows: RRC (Radio Resource Control) configures CSI reporting and associates it with CSI resource configuration, and configures the CSI-RS and / or SSB used for measurement.
[0072] Regarding the number of configurable reference signal sets, there are the following limitations: for periodic and semi-persistent CSI-RS, only one resource set can be configured; for non-periodic CSI-RS, multiple resource sets can be configured, but only one resource set can be activated.
[0073] In addition, the rate matching mechanism for PDSCH (Physical Downlink Shared Channel) needs to consider CSI-RS. Existing rate matching mechanisms related to CSI-RS are as follows:
[0074] 1) PDSCH is not sent on the RE (Resource Element) occupied by ZP (Zero Power) CSI-RS;
[0075] 2) PDSCH resource mapping should avoid REs of NZP (Non-Zero Power) CSI-RS, except for CSI-RS for mobility and AP NZP CSI-RS.
[0076] To support users moving at high speeds in high-frequency scenarios, beam measurement and reporting of neighboring cells is currently under discussion. If the UE can measure the CSI-RS of neighboring cells and report the corresponding L1-RSRP or L1-SINR results, then the beam quality of the neighboring cells can be measured. However, how to achieve neighboring cell beam measurement has become an urgent problem to be solved.
[0077] To address the aforementioned problems, this invention provides an information transmission method and apparatus, wherein the method and apparatus are based on the same concept. Since the methods and apparatus solve problems in similar principles, their implementations can be mutually referenced, and repeated details will not be elaborated further.
[0078] like Figure 1 The diagram shown is a flowchart of an information transmission method provided in an embodiment of the present invention. This method is applied to a network-side device and includes:
[0079] Step 101: Send first configuration information to the terminal, the first configuration information including M sets of reference signals;
[0080] In other words, the network-side device configures M sets of reference signals for reporting L1-RSRP or L1-SINR. The network-side device sends first configuration information, including these M sets of reference signals, to the terminal so that the terminal is aware of the candidate sets of reference signals, i.e., the M sets of reference signals, that can be used for beam measurement.
[0081] Step 102: Send a reference signal activation instruction to the terminal. The reference signal activation instruction is used to activate N reference signal sets out of M reference signal sets, where M > 1, N ≤ M, and M and N are both positive integers.
[0082] In this step, the network-side device sends a reference signal activation instruction to the terminal. The purpose of this instruction is to indicate which reference signal sets the terminal can activate and which reference signal sets can be used to perform subsequent beam measurements.
[0083] Step 103: Receive the measurement results sent by the terminal after performing beam measurement based on N sets of reference signals. The measurement results include the Layer 1 reference signal received power L1-RSRP or the Layer 1 signal to interference plus noise ratio L1-SINR.
[0084] It should be noted that the terminal performs beam measurement based on the N reference signal sets activated by the network-side device and reports the measurement results, including L1-RSRP or L1-SINR. Since L1-RSRP or L1-SINR is closer to instantaneous measurement, it can realize the measurement of beam quality corresponding to high-speed mobile users in high-frequency scenarios.
[0085] In the information transmission method of this invention, the network-side device sends first configuration information to the terminal, the first configuration information including M reference signal sets; sends a reference signal activation indication to the terminal, the reference signal activation indication being used to activate N reference signal sets among the M reference signal sets, where M>1, N≤M, and M and N are both positive integers; and receives the measurement results sent by the terminal after performing beam measurement based on the N reference signal sets, the measurement results including Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR. Thus, for users moving at high speed in high-frequency scenarios, neighboring cell beam measurement can be achieved.
[0086] Optionally, the reference signal activation indication includes:
[0087] MAC-CE signaling, wherein the MAC-CE signaling is used to instruct the terminal to activate N reference signal sets from the M reference signal sets in the first configuration information; or...
[0088] DCI signaling, wherein the DCI signaling is used to instruct the terminal to activate N reference signal sets from the M reference signal sets of the first configuration information.
[0089] In other words, sending a reference signal activation instruction to the terminal can specifically include:
[0090] Send MAC-CE (Media Access Control-Control Element) signaling or DCI (Downlink Control Information) signaling to the terminal.
[0091] Specifically, when the reference signal activation indication is MAC-CE signaling, the terminal activates N reference signal sets from the M reference signal sets configured in the CSI report according to the MAC-CE signaling.
[0092] It should be noted that the first configuration information at this time is the CSI reporting configuration, which includes M sets of reference signals.
[0093] When the reference signal activation indication is DCI signaling, the terminal activates N reference signal sets corresponding to the trigger state of aperiodic CSI-RS from the M reference signal sets in the first configuration information according to the trigger state of aperiodic CSI-RS in the DCI signaling.
[0094] Optionally, the reference signal set includes reference signals associated with a first cell, the cell identifier value of which is different from the cell identifier value of the serving cell.
[0095] In other words, the first community is not a service community.
[0096] Furthermore, the reference signal associated with the first cell is a reference signal that is directly or indirectly quasi-co-located with the reference signal of the first cell.
[0097] The existing CSI-RS for mobility is used for L3-RSRP measurement, which can be obtained through time averaging. Therefore, R15 / R16 does not puncture the PDSCH and CSI-RS for mobility of the cell, meaning no rate matching is performed, and there is no mutual interference with the PDSCH. However, for users moving at high frequencies in high-frequency scenarios, L1-RSRP is closer to instantaneous measurement. If rate matching is not performed, mutual interference with the PDSCH may prevent the acquisition of neighboring cell beam measurement results. To solve the above problem, rate matching is required. One possible implementation method is:
[0098] If the activated reference signal associated with the first cell is a periodic reference signal or a semi-persistent reference signal, then the Physical Downlink Shared Channel (PDSCH) cannot be mapped onto the resource element occupied by the activated reference signal associated with the first cell.
[0099] In this way, the resource mapping of PDSCH avoids the resource elements occupied by the activated reference signal associated with the first cell, which solves the mutual interference between the terminal beam measurement and PDSCH, and the network-side equipment can obtain the neighboring cell beam measurement results.
[0100] In the information transmission method of this invention, the network-side device sends first configuration information to the terminal, the first configuration information including M reference signal sets; sends a reference signal activation indication to the terminal, the reference signal activation indication being used to activate N reference signal sets among the M reference signal sets, where M>1, N≤M, and M and N are both positive integers; and receives the measurement results sent by the terminal after performing beam measurement based on the N reference signal sets, the measurement results including Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR. Thus, for users moving at high speed in high-frequency scenarios, neighboring cell beam measurement can be achieved.
[0101] like Figure 2 The diagram shows a flowchart of an information transmission method provided in an embodiment of the present invention. This method is applied to a terminal and includes:
[0102] Step 201: Receive first configuration information sent by the network-side device, the first configuration information including M sets of reference signals;
[0103] In this step, the terminal learns the set of candidate reference signals configured by the network side and capable of beam measurement by receiving the first configuration information sent by the network side, namely the M reference signal sets.
[0104] Step 202: Receive the reference signal activation instruction sent by the network-side device;
[0105] Here, the terminal receives a reference signal activation instruction sent by the network-side device and performs subsequent activation operations.
[0106] Step 203: According to the reference signal activation instruction, activate N reference signal sets out of M reference signal sets, where M > 1, N ≤ M, and M and N are both positive integers;
[0107] Here, the terminal activates the corresponding reference signal set through the reference signal activation instruction, that is, activates N reference signal sets out of M reference signal sets, so that the terminal can subsequently perform beam measurement using the activated reference signal sets.
[0108] Step 204: Perform beam measurement based on the N reference signal sets to obtain the measurement results;
[0109] Step 205: Send the measurement results to the network-side device. The measurement results include Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR.
[0110] It should be noted that, since the reported L1-RSRP or L1-SINR is closer to the instantaneous measurement, network-side devices can determine the corresponding beam quality based on the L1-RSRP or L1-SINR reported by the terminal for users moving at high speeds in high-frequency scenarios.
[0111] In this embodiment of the invention, by receiving first configuration information sent by a network-side device, the first configuration information including M reference signal sets; receiving a reference signal activation indication sent by the network-side device; activating N reference signal sets from the M reference signal sets according to the reference signal activation indication, where M > 1, N ≤ M, and M and N are both positive integers; performing beam measurement based on the N reference signal sets to obtain measurement results; and sending the measurement results to the network-side device, the measurement results including Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR, thus enabling neighboring cell beam measurement for users moving at high speeds in high-frequency scenarios.
[0112] Optionally, the reference signal activation indication includes:
[0113] MAC-CE signaling, wherein the MAC-CE signaling is used to instruct the terminal to activate N reference signal sets from the M reference signal sets in the first configuration information; or...
[0114] DCI signaling, wherein the DCI signaling is used to instruct the terminal to activate N reference signal sets from the M reference signal sets of the first configuration information.
[0115] In other words, the reference signal activation indication sent by the receiving network-side device can specifically include:
[0116] Receive MAC-CE or DCI signaling sent by network-side devices.
[0117] Further, according to the reference signal activation instruction, activating N reference signal sets out of the M reference signal sets includes:
[0118] When the reference signal activation indication is MAC-CE signaling, the terminal activates N reference signal sets from the M reference signal sets configured in the CSI report according to the MAC-CE signaling.
[0119] It should be noted that the first configuration information at this time is the CSI reporting configuration, which includes M sets of reference signals.
[0120] When the reference signal activation indication is DCI signaling, the terminal activates N reference signal sets corresponding to the trigger state of aperiodic CSI-RS from the M reference signal sets in the first configuration information according to the trigger state of aperiodic CSI-RS in the DCI signaling.
[0121] Optionally, the reference signal set includes reference signals associated with a first cell, the cell identifier value of which is different from the cell identifier value of the serving cell.
[0122] Furthermore, the reference signal associated with the first cell is a reference signal that is directly or indirectly quasi-co-located with the reference signal of the first cell.
[0123] Optionally, if the activated reference signal associated with the first cell is a periodic reference signal or a semi-persistent reference signal, then the Physical Downlink Shared Channel (PDSCH) cannot be mapped onto the resource element occupied by the activated reference signal associated with the first cell.
[0124] The information transmission method of this invention involves receiving first configuration information sent by a network-side device, the first configuration information including M reference signal sets; receiving a reference signal activation indication sent by the network-side device; activating N reference signal sets from the M reference signal sets according to the reference signal activation indication, where M > 1, N ≤ M, and M and N are both positive integers; performing beam measurement based on the N reference signal sets to obtain measurement results; and sending the measurement results to the network-side device, the measurement results including Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR. Thus, for users moving at high speeds in high-frequency scenarios, neighboring cell beam measurement can be achieved.
[0125] like Figure 3 As shown, this embodiment of the invention also provides an information transmission device, which includes:

[0128] The first receiving module 303 is used to receive the measurement results sent by the terminal after performing beam measurement based on N sets of reference signals. The measurement results include the layer 1 reference signal received power L1-RSRP or the layer 1 signal to interference plus noise ratio L1-SINR.
[0129] Optionally, the reference signal activation indication includes:
[0130] MAC-CE signaling, wherein the MAC-CE signaling is used to instruct the terminal to activate N reference signal sets from the M reference signal sets in the first configuration information; or...

[0132] Optionally, the reference signal set includes reference signals associated with a first cell, the cell identifier value of which is different from the cell identifier value of the serving cell.
[0133] Optionally, the reference signal associated with the first cell is a reference signal that is directly or indirectly quasi-co-located with the reference signal of the first cell.
[0134] Optionally, if the activated reference signal associated with the first cell is a periodic reference signal or a semi-persistent reference signal, then the Physical Downlink Shared Channel (PDSCH) cannot be mapped onto the resource element occupied by the activated reference signal associated with the first cell.
[0135] The information transmission device of this invention sends first configuration information to a terminal, the first configuration information including M reference signal sets; sends a reference signal activation instruction to the terminal, the reference signal activation instruction being used to activate N reference signal sets among the M reference signal sets, M>1, N≤M, and M and N are both positive integers; and receives a measurement result sent by the terminal after performing beam measurement based on the N reference signal sets, the measurement result including Layer 1 reference signal received power L1-RSRP or Layer 1 signal-to-interference-plus-noise ratio L1-SINR.
