Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information processing method, apparatus and network-side equipment. Background Technology

[0002] In indoor distributed antenna systems, there is a scenario called HUB (hub) merging (i.e., merging PICO RRUs using a HUB). This involves merging the antenna channels of multiple RRUs (remote radio units) in the time domain before sending them to the BBU (baseband processing unit) for analysis. This reduces the number of channels sent to the BBU, thereby reducing the amount of data transmitted from the RRUs to the BBU and the processing complexity of the BBU.

[0003] For example, Figure 1 As shown, there are 8 PICOs (i.e., PICO RRUs: Indoor Distributed Radio Remote Units), each with 4 channels, for a total of 32 channels. To reduce the data transmission volume from the hub to the base unit (BBU), PICOs are merged in pairs, i.e., hub channel merging (two-in-one). The 8 PICOs are numbered P1 to P8, where P1 / P2 are merged, P3 / P4 are merged, and so on. The merged RRUs are numbered H1, H2, H3, and H4, respectively. That is, channel 1 of P1 and channel 1 of P2 are merged, channel 2 of P1 and channel 2 of P2 are merged, and so on. The merged 4-channel group is a single RRU, numbered H1. Similarly, the merged RRUs of channels from P3 and P4 are numbered H2, and so on.

[0004] Furthermore, for downlink signal transmission, two methods can be used: either full PICO repetition (where each PICO transmits the same downlink signal) or selective transmission (where only a subset of PICOs are transmitted). For selective transmission, the base station can determine which PICOs a user belongs to based on the quality measurement results of the uplink SRS (Channel Sound Reference) received signal, thus determining which PICOs at the base station will transmit the downlink signal.

[0005] However, since the BBU can only measure the quality of each RRU based on the SRS signals of H1-H4 after merging the PICO RRUs using the HUB, it cannot separate the difference between P1 and P2 from H1. Similarly, it cannot separate the difference between P3 and P4 from the quality measurement of H2, and so on.

[0006] Based on the above, in the existing technology, if performance requirements are met, only some PICOs can be selected for downlink signal transmission, while some PICOs are not suitable for simultaneous use. For example, PICO1 and PICO2 are not suitable for transmitting downlink signals at the same time. However, the base station cannot determine that using PICO1 and PICO2 at the same time will lead to a deterioration in downlink signal quality.

[0007] From the above, in the prior art, in the scenario of combining PICO RRU by using HUB, there is a problem that a suitable PICO RRU cannot be determined for information transmission. SUMMARY

This can select a suitable PICO RRU for information transmission in a scenario of HUB merging, and can improve the downlink rate of the PICO RRU in the scenario of HUB merging, and can solve the problem that a suitable PICO RRU cannot be determined for information transmission in the scenario of HUB merging PICO RRUs in the prior art.

[0144] Further, before sending the measurement signals to the terminal through corresponding first PICO RRUs according to configuration information of the measurement signals corresponding to each first PICO RRU in a first PICO RRU candidate set, the method further includes: performing quality measurement according to a channel sounding reference signal SRS of a second PICO RRU to obtain a measurement quality value; and obtaining the second PICO RRU candidate set according to the second PICO RRUs whose measurement quality values are greater than or equal to a first threshold.

[0145] This can further ensure that a suitable PICO RRU can be selected for sending downlink information; wherein the quality measurement according to the SRS can be measurement of received power or signal-to-noise ratio, which is not limited herein.

[0146] In the embodiments of the present application, the measurement signal can include a downlink channel state information reference signal (CSIRS) or a synchronization signal block (SSB) beam.

[0147] In the embodiments of the present application, when the measurement signal includes the CSIRS, the configuration information includes time-frequency resource information; the time-frequency resource corresponding to the time-frequency resource information is periodic resource, each first PICO RRU included in one second PICO RRU corresponds to different periodic CSIRS resource sets, or each first PICO RRU included in one second PICO RRU corresponds to different CSIRS resources in one periodic CSIRS resource set, and a CSIRS reporting period is less than a CSIRS sending period; or the time-frequency resource corresponding to the time-frequency resource information is aperiodic resource, each first PICO RRU included in one second PICO RRU corresponds to the same set of aperiodic CSIRS resources.

[0148] In this way, it is more convenient to perform measurement to select a suitable target PICO RRU.

[0149] In the embodiments of the present application, the measurement report information includes channel state information (CSI) and CSI resource index (CRI) information corresponding to at least one first PICO RRU; and the target PICO RRU for sending downlink information to the terminal is determined from the first PICO RRU candidate set according to the measurement report information, including: the target PICO RRU for sending downlink information to the terminal is determined from the first PICO RRU candidate set according to the CSI and CRI information.

[0150] In addition, when the measurement signal includes the SSB beam, the configuration information includes beam information, each first PICO RRU included in one second PICO RRU corresponds to different SSB beams; the measurement report information includes index information of the SSB beam and a reference signal receiving power (RSRP) measurement value; and the target PICO RRU for sending downlink information to the terminal is determined from the first PICO RRU candidate set according to the measurement report information, including: the target PICO RRU for sending downlink information to the terminal is determined from the first PICO RRU candidate set according to the index information of the SSB beam and the RSRP measurement value.

[0151] In this way, it is also convenient to perform measurement to select a suitable target PICO RRU.

[0152] Further, before receiving the measurement report information fed back by the terminal, the method further comprises: configuring the terminal to report measurement report information corresponding to L SSB beams; wherein L is an integer greater than zero; and L is less than or equal to the total number of first PICO RRUs included in a second PICO RRU.

[0153] Specifically, the terminal can be configured to report measurement report information corresponding to L SSB beams with the strongest signals, but the application is not limited thereto.

[0154] In the embodiments of the application, each first PICO RRU included in a second PICO RRU corresponds to configuration information of different measurement signals; and / or, the first PICO RRUs included in different second PICO RRUs correspond to configuration information of the same or different measurement signals.

[0155] It can also be understood that each first PICO RRU included in a HUB corresponds to configuration information of different measurement signals; and / or, the first PICO RRUs included in different HUBs correspond to configuration information of the same or different measurement signals.

[0156] Specifically, the first PICO RRUs with the same number in different HUBs can correspond to configuration information of the same measurement signal, which can save resources, but the application is not limited thereto.

[0157] Further, before sending the measurement signals corresponding to each first PICO RRU in the first indoor distributed radio frequency remote unit PICO RRU candidate set to the terminal through the corresponding first PICO RRU according to the configuration information of the measurement signals, the method further comprises: configuring each first PICO RRU included in the second PICO RRU with a set of measurement signals; and notifying the HUB that combines the first PICO RRUs of the configuration information of the measurement signals corresponding to each first PICO RRU through a common public radio interface CPRI transmission channel.

[0158] In this way, the subsequent processing speed can be accelerated.

[0159] The method comprises the following steps: obtaining the measurement signal; transmitting the measurement signal to the corresponding HUB through a baseband processing unit (BBU) via a common public radio interface (CPRI) transmission channel; determining the corresponding first PICO RRU of the measurement signal in the first PICO RRU candidate set by using the HUB; and transmitting the measurement signal to the terminal by the corresponding first PICO RRU by using the HUB.

[0160] In the embodiment, the HUB is used to determine the corresponding first PICO RRU of the measurement signal in the first PICO RRU candidate set, which comprises the following steps: the HUB is used to determine the corresponding first PICO RRU of the measurement signal according to the identification information transmitted by the CPRI transmission channel; or the HUB is used to determine the corresponding first PICO RRU of the measurement signal according to the configuration information of the measurement signal corresponding to each first PICO RRU.

[0161] In this way, the corresponding first PICO RRU of the measurement signal can be determined flexibly.

[0162] In the embodiment, the HUB is used to transmit the measurement signal to the terminal by the corresponding first PICO RRU, which comprises the following steps: in the case that at least two second PICO RRUs contain the corresponding first PICO RRU of the measurement signal, the measurement signal is transmitted to the terminal on all the corresponding first PICO RRUs of the measurement signal respectively.

[0163] In this way, the configuration consumption of the measurement signal can be reduced when the measurement is performed on multiple first PICO RRUs.

[0164] The information processing method provided by the embodiment will be further described below in combination with a network side device and a terminal. The network side device is taken as an example of a base station (the base station comprises a BBU and a HUB), and the PICO RRU is abbreviated as PICO.

[0165] To solve the above technical problems, the embodiment provides an information processing method, which can be specifically implemented as a judgment method based on the combination of terminal feedback and base station uplink received signal measurement, and involves the following aspects:

[0166] 1. The number of PICO combined by each HUB is N = 2, 4 or 8, or other number of PICO, the network side high layer configures N downlink CSIRS (channel state information reference signal) or N SSB (synchronization signal block) beams for the base station and the terminal, which is assumed to be named measurement signal, and the measurement signal in the subsequent description refers to CSIRS or SSB beam. The processing steps of the base station include:

[0167] (1) The base station high layer configures a set of measurement signals for each PICO combined by the HUB, and notifies the HUB of the configuration information of the measurement signal corresponding to each PICO through the CPRI (common public radio interface) transmission channel.

[0168] 1) If there are multiple groups of PICO combined by the HUB, the same measurement signal configuration is used between each group of PICO combined by the HUB; it is assumed that there are 4 groups of HUB, each group of HUB combined contains 2 PICO, and the PICO numbered 1 in the 4 groups of HUB is configured with the first set of measurement signals, and the PICO numbered 2 in the 4 groups of HUB is configured with the second set of measurement signals.

[0169] (2) After the base station BBU generates the measurement signal sending data on different time-frequency resources, it is transmitted to the HUB through the CPRI transmission channel for downlink transmission.

[0170] 1) The information transmitted through the CPRI transmission channel at the same time can include which PICO the measurement signal corresponds to (corresponding to the above using the HUB to determine the first PICO RRU corresponding to the measurement signal according to the identification information transmitted by the CPRI transmission channel); or the HUB automatically identifies which PICO the measurement signal transmitted by the current BBU corresponds to through the pre-informed configuration information of the measurement signal (corresponding to the above using the HUB to determine the first PICO RRU corresponding to the measurement signal according to the configuration information of the measurement signal corresponding to each first PICO RRU).

[0171] The HUB transmits the measurement signal on the corresponding PICO according to the PICO corresponding to the current measurement signal (corresponding to the above using the HUB to transmit the measurement signal to the terminal through the corresponding first PICO RRU).

[0172] 2) If there are multiple groups of HUB, the measurement signal is transmitted on the corresponding PICO in each HUB (corresponding to the above in the case that at least two second PICO RRUs both contain the first PICO RRU corresponding to the measurement signal, the measurement signal is transmitted on all first PICO RRUs corresponding to the measurement signal to the terminal respectively).

[0173] The subsequent terminal can report the measurement of the received measurement signal. The existing method can be used, and details are not described herein.

[0174] 2. The judgment process of the base station to the PICO to which the user belongs can be as follows:

[0175] First, the RRU number that meets the requirements is selected according to the method of distinguishing RRUs (corresponding to the number of the second PICO RRU), and then the PICO number in the RRU is selected according to the method of distinguishing N PICO merged by the HUB (corresponding to the number of the first PICO RRU). Finally, the PICO index that can perform downlink signal transmission (corresponding to the target PICO RRU determined from the first PICO RRU candidate set for transmitting downlink information to the terminal) is obtained; in particular:

[0176] (1) Assuming that the RRU (i.e., the second PICO RRU) output after the HUB merging is H1, H2, …, Hm, the method of distinguishing RRUs can be as follows:

[0177] The base station performs quality measurement (such as measuring the received power or the signal-to-noise ratio) based on the SRS of H1 to Hm, judges whether the measurement quality exceeds a given threshold (corresponding to the first threshold), and determines the PICO (i.e., the first PICO RRU) that can perform downlink transmission. If the SRS quality measurement of a certain RRU (i.e., the second PICO RRU) meets the quality requirement for transmission, all PICO (i.e., the first PICO RRU) under the HUB merging of the RRU are selected into the candidate set for transmitting downlink signals (i.e., the first PICO RRU candidate set).

[0178] (2) The method of distinguishing N PICO (i.e., the first PICO RRU) merged by the HUB can be as follows:

[0179] The base station selects the optimal PICO or multiple PICO in the HUB merging according to the measurement report of one or more sets of measurement signals fed back by the terminal, judges whether the quality information of the set of measurement signals meets the threshold requirement according to the signal quality information (which can correspond to the channel information in the CSI or the RSRP measurement value) in the measurement report information, and selects the PICO as the PICO (i.e., the target PICO RRU) to which the user actually belongs among all PICO merged in the HUB. The threshold value can be determined according to product requirements.

[0180] 3. The following provides four different implementation schemes (configuration methods) for configuring measurement signals for distinguishing N PICO merged by the HUB.

[0181] Scheme one (corresponding to the case that the measurement signal includes CSIRS, the time-frequency resource corresponding to the time-frequency resource information is periodic resource, each first PICO RRU of one HUB corresponds to different periodic CSIRS resource set):

[0182] Configure N periodic CSIRS resource sets (resource set), each resource set is configured with a set of CSIRS and a set of measurement reporting (corresponding to the above measurement reporting parameter information). The base station obtains the CRI (which can be used to indicate the identity of the CSIRS) and CSI information of each set of CSIRS fed back by the terminal, and selects the PICO that meets the downlink transmission index requirement according to the CRI and CSI (which can be the channel information in the CSI), which can select the optimal one, or select multiple PICO.

[0183] Scheme two (corresponding to the case that the measurement signal includes CSIRS, the time-frequency resource corresponding to the time-frequency resource information is periodic resource, each first PICO RRU of one HUB corresponds to different CSIRS resource in one periodic CSIRS resource set, and the CSIRS reporting period is less than the CSIRS transmission period):

[0184] Configure 1 periodic CSIRS resource set, which includes N sets of CSIRS resources, and configure a set of measurement reporting. Configure the CSIRS reporting period to be less than the CSIRS transmission period, and (the terminal) reports according to the latest measured CRI at different reporting times to achieve the purpose that multiple sets of CSIRS can be reported. The base station obtains the CRI and CSI information of each set of CSIRS fed back by the terminal, and selects the PICO that meets the downlink transmission index requirement according to the CRI and CSI (which can be the channel information in the CSI), which can select the optimal one, or select multiple PICO.

[0185] Scheme three (corresponding to the case that the measurement signal includes CSIRS, the time-frequency resource corresponding to the time-frequency resource information is non-periodic resource, each first PICO RRU of one HUB corresponds to the same set of non-periodic CSIRS resource):

[0186] Configure 1 non-periodic CSIRS resource set, which includes a set of non-periodic CSIRS resources, and configure a set of non-periodic measurement reporting. The base station allows non-periodic CSIRS to be sent on different PICO at different times through real-time scheduling, and determines the quality of the PICO according to the feedback. The base station obtains the CRI and CSI information of N PICO fed back by the terminal, and selects the PICO that meets the downlink transmission index requirement according to the CRI and CSI (which can be the channel information in the CSI), which can select the optimal one, or select multiple PICO.

[0187] Scheme four (corresponding to the case where the measurement signal includes SSB beam, the configuration information includes beam information, each first PICO RRU of one HUB combination corresponds to different SSB beam; the measurement report information includes the index information of SSB beam and the reference signal receiving power RSRP measurement value):

[0188] The number of SSB multi-beams is configured as N, each PICO transmits one beam, and the terminal is configured to select L SSB measurements for reporting, L is not greater than N (L can be determined according to terminal capability), and the measurement report information includes the index of the strongest L SSB beams (i.e. the above index information) and the RSRP (reference signal receiving power) measurement value. The base station obtains the SSB RSRP information of the optimal L PICO fed back by the terminal, and selects the PICO meeting the downlink transmission index requirement according to the RSRP, which can select the optimal one or multiple PICO (corresponding to the above determination of the target PICO RRU for transmitting downlink information to the terminal from the first PICO RRU candidate set according to the index information of the SSB beam and the RSRP measurement value).

[0189] The scheme provided by the embodiments of the present application is specifically illustrated below.

[0190] Suppose there are 8 PICO (i.e. first PICO RRU), each PICO has 4 channels, and the total number is 32 channels (see Figure 1 ). In order to reduce the data transmission amount of HUB to BBU, two PICO combination is performed, that is, HUB channel combination two-in-one. 8 PICO, numbered P1 to P8, wherein P1 / P2 combination, P3 / P4 combination, …… The combined RRU (i.e. second PICO RRU) is numbered as H1, H2, H3, H4. That is, the channel 1 of P1 and the channel 1 of P2 are combined, the channel 2 of P1 and the channel 2 of P2 are combined, ……, the combined four channel groups are combined as one RRU, numbered as H1, and by analogy, the combined RRU of each channel of P3 and P4 is numbered as H2, …… The combined four RRUs measure SRS signal quality as S1, S2, S3 and S4. In this scheme:

[0191] First, RRU (i.e. second PICO RRU) selection is performed, and the base station determines the PICO (i.e. first PICO RRU) that the user can transmit downlink based on whether the SRS quality measurement (which can be received power or signal-to-noise ratio) of H1 to H4 exceeds a given threshold. If the SRS quality measurement of a certain RRU meets the quality requirement of transmission, all PICO (i.e. first PICO RRU) under the RRU (i.e. second PICO RRU) are selected into the candidate set for transmitting downlink signal. It is assumed that the SRS measurement of H2 and H4 meets the threshold requirement.

[0192] Then, the PICO to which the user (terminal) belongs is determined again. It is assumed that according to the feedback of the terminal, it is determined that only the first PICO (also can be understood as the PICO numbered 1) in the two PICO (namely, the first PICO RRU) satisfies the requirement of downlink transmission, and the finally selected PICO (namely, the target PICO RRU) is the first PICO in H2 and the first PICO in H4, that is, P3 and P7 in P1 to P8.

[0193] From the above, it can be seen that the scheme provided by the embodiments of the present application can improve the downlink rate of the PICO in the HUB merging scenario.
