[0028] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several UEs 11 and several access devices 12 .

[0029] Among them, UE11 can refer to a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote UE (remote terminal), an access terminal, a user terminal, a user agent, a user device, or a user UE (user equipment, UE).

Alternatively, UE11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0030] The access device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

[0031] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

The embodiments of the present disclosure do not limit the implementation form of the network management device 13.

[0036] like Figure 2 As shown, the embodiment of the present disclosure provides an information processing method, which is applied in a base station, including:

[0037] S110: Configure configuration information of a reference signal according to a user equipment UE type, wherein the reference signal includes at least one of the following: a TRS; and a CSI-RS.

[0038] In the embodiment of the present disclosure, the configuration of the reference signal is configured according to the UE type. After the configuration information is configured, it will be sent to the UE for the UE to monitor the reference signal according to the configuration information.

[0039] In one embodiment, the UE type may be divided according to the bandwidth supported by the UE; for example, some UEs support a large bandwidth, while some UEs support a relatively small bandwidth.

[0040] In one embodiment, the UE types can also be divided based on UE capabilities. For example, some UEs have transceivers with high transmission rates, while others have relatively low transmission rates. For another example, some UEs have processors with high processing capabilities, while others have relatively low processing capabilities. UEs with relatively low processing capabilities require longer signal encoding and decoding times.

[0041] In one embodiment, the UE types may be classified based on the allowed standby time. For example, IoT devices require low power consumption to achieve an extremely long standby time, while UEs such as mobile phones may have less power consumption restrictions because users may charge them.

[0042] Different types of UEs have different requirements for receiving and / or using reference signals. In order to configure reference signals suitable for different types of UEs, in the embodiments of the present disclosure, configuration information of the reference signals is configured according to the UE type.

[0043] In some embodiments, the step 110 may include configuring reference signal configuration information for a UE in a non-connected state according to the UE type. The non-connected state UE includes at least an idle state and / or an inactive state UE.

[0044] In view of this, in one embodiment, the reference signal may be any reference signal originally configured for a connected UE. That is, the reference signal may not be a newly introduced signal, but may be any reference signal already configured in the related art. This has the characteristic of strong compatibility with the related art.

[0045] In the embodiment of the present disclosure, in the process of determining the configuration information of the reference signal, taking into account the use of the UE in the non-connected state, it is necessary to take into account the characteristics of the non-connected state, and introduce further configuration of the configuration information of the reference signal according to the UE type, so as to configure the use of the reference signal suitable for the UE in the non-connected state and any state in the connected state.

[0046] Of course, in another embodiment, the reference signal may be a reference signal configured solely for use by a UE in a non-connected state.

[0047] The reference signal includes at least: TRS and / or CSI-RS.

[0048] In one embodiment, the reference signal may be a reference signal that originally has a first function; in the embodiment of the present disclosure, the reference signal may also be used for a second function; the second function may be different from the first function.

[0049] Exemplarily, the TRS is originally intended to be used for UE phase tracking; the CSI-RS can be used to obtain channel state information.

[0050] In an embodiment of the present disclosure, the original first function of the TRS as the reference signal may be: phase tracking; and the original first function of the CSI-RS as the reference signal may be for obtaining channel state information. The second function of the TRS may include: adjustment of the automatic gain control (AGC) of the UE, radio resource management (RRM) of the UE and / or time-frequency domain synchronization between the UE and the base station. Similarly, the second function of the CSI-RS may also include: increase of the AGC of the UE, RRM of the UE, and / or time-frequency domain synchronization between the UE and the base station. In an embodiment of the present disclosure, the time-frequency domain synchronization may include: time domain synchronization between the UE and the base station, and / or alignment of the UE and the base station in the frequency domain.

[0051] In summary, in the embodiments of the present disclosure, the configuration information of the reference signal configured according to the UE type will configure the reference signal specifically and specifically according to the UE of the corresponding type of UE, so that the reference signal will be suitable for the characteristics required by the UE to perform the corresponding function.

[0052] The configuration information of the reference signal includes at least one of the following:

[0053] Resource allocation of reference signals;

[0054] Reference signal sequence configuration, for example, the reference signal sequence configuration, reference signal sequence generation parameters, etc.;

[0055] a quasi colocation (QCL) configuration of a reference signal, the QCL configuration including at least QCL parameters;

[0056] Configuration of the number of reference signals;

[0057] Period configuration of the reference signal;

[0058] Functional configuration of the reference signal; for example, the functional configuration indicates whether it is used for the second function, and / or which specific sub-function of the second function is used;

[0059] The effective configuration of the preset reference number, for example, the effective configuration of the reference signal, may be used to indicate the effective condition and / or effective timing of the configuration information for the reference signal;

[0060] The offset configuration between the reference signal and other reference signals may include: an offset configuration in the time domain and / or an offset configuration in the frequency domain.

[0061] Of course, the above is only an example of the configuration information of the reference signal. In actual implementation, the specific content of the configuration information is not limited to the above example.

[0062] In another embodiment, the reference signal can be used for time-frequency domain synchronization between an idle or inactive UE and a base station; or, the reference signal can be used for radio resource management RRM measurement of an idle or inactive UE.

[0063] In some embodiments, the TRS / CSI-RS can be used for time-frequency synchronization between a non-connected UE and a base station. In related technologies, reference signals used for time-frequency synchronization between a UE and a base station may include a synchronization signal block (Synchronization Signal and PBCH block, SSB). PBCH stands for Physical Broadcast Channel.

[0064] Due to the configuration flexibility of TRS / CSI-RS, TRS / CSI-RS, which is equivalent to SSB, can be configured closer to the UE's paging occasion (Paging Occasion, PO) in the time and frequency domain. In this way, when a UE enters a low-power inactive or idle state and wakes up at the PO to listen to the paging message, it also listens to the reference signal, thereby reducing the number of SSBs monitored, thereby reducing the high power consumption caused by multiple wake-ups or a long duration of one wake-up, thereby further saving the power consumption of the UE.

[0065] In some embodiments, the UE may enter a discontinuous reception (DRX) state. In the DRX state, the UE switches between a connected state and a non-connected state according to a DRX cycle or an extended DRX cycle. The DRX cycle and / or the eDRX cycle are respectively provided with a wake-up time and a sleep time; during the sleep time, the UE is in a non-connected state; during the wake-up time, the UE is in a connected state. Usually, the UE needs to enter a connected state to monitor PDCCH or PO or monitor SSB and other signals used to maintain time-frequency domain synchronization with the base station. Therefore, in the embodiment of the present disclosure, TRS / CSI-RS is used to replace other reference signals with more limitations designed on SSB in the time-frequency domain for the UE to perform time-frequency domain synchronization with the base station. The time-frequency domain position of the reference signal can be flexibly configured according to the type of UE to save the power consumption of the UE, etc.

[0066] In another embodiment, the reference signal can also be used to replace at least part of the SSB as RRM measurement, which can also reduce the duration or number of times the UE enters a high power consumption state such as a connected state, thereby also saving the power consumption of the UE.

[0067] In some embodiments, the UE includes at least: a first type UE and / or a second type UE; wherein the bandwidth supported by the first type UE is greater than the bandwidth supported by the second type UE. That is, the UE types include: a first type and a second type; the first type UE is the first type UE; and the second type UE is the second type UE.

[0068] Exemplarily, the first type UE may be an enhanced Mobile Broadband (eMBB) UE, and the second type UE may be a Redcap UE.

[0069] Exemplarily, the type of the UE may not be limited to the first type UE and the second type UE, and may also include a third type UE, etc.

[0070] In some embodiments, the configuration information of the reference signal is also used for phase tracking and / or obtaining channel state information of a UE in a connected state; the UE in a connected state includes: the first type UE in a connected state and / or the second type UE in a connected state.

[0071] At this time, the configuration information of the reference signal is used for both connected and non-connected UEs. This is equivalent to the connected UEs and non-connected UEs sharing a set of reference signal configurations, which at least improves the effective utilization rate of the time-frequency resources consumed by the reference signal.

[0072] In some embodiments, if the configuration information of the reference signal is for both connected and non-connected UEs; if all connected UEs of a certain type are cut off from the cell, the network side can reclaim the resource configuration of the reference signal. In this way, the resource configuration of the reference signal will affect the use of the reference signal by the corresponding type of non-connected UEs. Exemplarily, in this case, the base station can configure the reference signal only for the non-connected UE of that type based on the UE type.

[0073] In another embodiment, at least the configuration information of the reference signal for the second type of UE is not used for phase tracking and / or acquiring channel state information of the UE in the connected state.

[0074] The bandwidth supported by the second type UE is smaller than that of the first type UE. For example, the maximum bandwidth supported by the first type UE may be 20 MHz, while the maximum bandwidth supported by the first type UE may be as high as 100 MHz. The reference signal for the second type UE may not need to use the first type UE, and the configuration of the reference signal for the second type UE at least occupies fewer frequency domain resources. The reference signal configuration for the second type UE in the reference signal configuration information may only be applicable to the second type UE in the non-connected state and not to the first type UE in the non-connected state; or, it may only be applicable to the first type UE and / or the second type UE in the non-connected state and not to the first type UE in the non-connected state, etc.

[0075] Whether the reference signal configuration for the first type of UE and / or the second type of UE in the configuration information can be used for connected UE or which type of connected UE it is applicable to can be comprehensively determined based on the network environment and / or network capacity and / or the number of UE accesses.

[0076] In one embodiment, the first type UE is an enhanced mobile broadband (eMBB) UE; and / or, the second type UE is a reduced capability (Redcap) UE.

[0077] In one embodiment, the configuration information of the reference signal is for the first type UE and the second type UE in a connected state; or, the configuration information of the reference signal is for the first type UE in a connected state; or, the configuration information of the reference signal is for the second type UE in a connected state.

[0078] Here, the configuration information is for a connected first type UE and a connected second type UE, indicating that the reference signal corresponding to the configuration information is used for the connected first type UE and the connected second type UE. Similarly, the configuration information is for a connected first type UE, indicating that the reference signal corresponding to the configuration information is used for the connected first type UE. The configuration information is for a connected second type UE, indicating that the reference signal corresponding to the configuration information is used for the connected second type UE.

[0079] In some embodiments, the configuration information of the reference signal includes:

[0080] The first type UE and the second type UE share a common set of reference signal configurations.

[0081] The configuration information includes reference signal configuration, where the reference signal configuration includes but is not limited to the aforementioned resource configuration and other configurations.

[0082] If the first type UE and the second type UE share the same reference signal configuration, it means that the current configuration mode of the preset reference configuration signal is a common configuration.

[0083] If the first type UE and the second type UE share the same reference signal configuration, the first type UE and the second type UE will receive reference signals on the same time-frequency domain resources. To reduce unnecessary BWP switching of at least one type of UE, in one embodiment, in response to the first type UE and the second type UE sharing the same downlink initial BWP, the first type UE and the second type UE share the same reference signal configuration. Of course, the first type UE and the second type UE may not share the same downlink initial BWP. In this case, at least one type of UE may need to switch its working BWP when monitoring reference signals.

[0084] In some embodiments, the S110 may include:

[0085] In response to the first type UE and the second type UE sharing a set of reference signal configurations, configuration information of the reference signal is determined according to the second type UE.

[0086] Since the bandwidth supported by the second type of UE is smaller than the bandwidth supported by the first type of UE, in order to ensure that the configured reference signal is supported by the second type of UE, the reference signal can be directly configured based on the second type of UE to obtain the configuration information of the reference signal. Exemplarily, the reference signal is configured based on the bandwidth supported by the second type of UE; and / or the reference signal is configured based on the distribution position of the PO of the second type of UE in the time domain, etc.

[0087] In another embodiment, in response to the first type UE and the second type UE sharing a set of reference signal configurations, the configuration information of the reference signal is determined according to the first type UE, wherein the configuration information of the reference signal is used for the second type UE to select a part of the bandwidth supported by the second type UE within the bandwidth range of the reference signal to monitor the reference signal.

[0088] In the embodiment of the present disclosure, according to the second type UE, the configuration information for configuring the reference signal includes but is not limited to:

[0089] Configuring configuration information of the reference signal according to a bandwidth supported by the first type of UE;

[0090] and / or,

[0091] The configuration information of the reference signal is configured according to the distribution position of the PO of the first type UE in the time domain.

[0092] According to the configuration information of the reference signal configured with the bandwidth supported by the first type of UE, the transmission bandwidth of the reference signal may be the bandwidth supported by the first type of UE; and the bandwidth supported by the second type of UE is smaller than the bandwidth supported by the first type of UE. At this time, the first type of UE may receive the reference signal after bandwidth truncation according to the bandwidth supported by itself.

[0093] For example, assuming that the reference signal is configured at [A+BW1 / 2, A-BW1 / 2], BW1 may be the bandwidth supported by the first type of UE. The bandwidth supported by the second type of UE is BW2, and BW2 is smaller than BW1. At this time, any continuously distributed BW2 may be selected at [A+BW1 / 2, A-BW1 / 2] to receive the reference signal, thereby performing the first function and / or second function of the aforementioned reference signal according to the received reference signal. Exemplarily, the second type of UE may choose to receive the reference signal on A+BW1 / 2 to A+BW1 / 2-BW1; or receive the reference signal on A+-BW1 / 2 to A+-BW1 / 2+BW1. Of course, this is only an example, and the specific implementation is not limited to this.

[0094] In one embodiment, in response to the first type UE and the second type UE sharing a set of reference signal configurations, a change in the reference signal configuration information takes effect for the first type UE and the second type UE.

[0095] Since the first type UE and the second type UE share a set of reference signal configurations in a common configuration mode, the change of configuration information can take effect on both the first type UE and the second type UE at the same time. In this way, the reference signal configurations of the first type UE and the second type UE that share a set of reference signal configurations can take effect at the same time.

[0096] In some embodiments, the reference signal availability indication is applied to both the first type UE and the second type UE.

[0097] After the reference signal is configured, the network side may also issue an availability indication based on specific needs. The availability indication indicates whether the reference signal corresponding to the configuration information is available. If a reference signal is unavailable, there may be at least one of the following situations: the reference signal configuration is unreasonable, the reference signal resources are occupied, and the base station does not expect the UE to use the reference signal. Unreasonable reference signal configuration includes but is not limited to at least one of the following: the configured frequency domain position is too far away from the working BWP used by the UE, the configuration density of the reference signal is unreasonable, the distribution of the reference signal in the time domain does not meet the UE's service transmission requirements or the purpose of the UE to save power consumption, etc. Of course, the above is only an explanation of the unreasonable reference signal configuration, and the specific implementation is not limited to this.

[0098] Some services with very urgent priority, such as bursty ultra reliable and low latency communication (URLLC) services, preempt the transmission resources of the reference signal, making the reference signal unavailable.

[0099] The availability indicator may indicate whether the reference signal corresponding to the configuration information is available. If it is not available, the UE may not monitor the reference signal according to the configuration information, thereby reducing unnecessary monitoring.

[0100] In some embodiments, the configuration information of the reference signal includes:

[0101] a reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE;

[0102] The reference signal configuration for the first type UE is at least partially different from the reference signal configuration for the second type UE.

[0103] The first type UE and the second type UE share the same set of reference signal configurations, and the availability indication is effective for both the first type UE and the second type UE. In this way, the base station only needs to send the availability indication once to indicate whether the reference signals corresponding to the configuration information of the two types of UEs are available, which has the characteristic of low indication bit overhead.

[0104] In one embodiment, the S110 may include:

[0105] The configuration information in response to the reference signal includes: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, and according to the first type UE and the second type UE, the reference signal configuration for the first type UE and the reference signal configuration for the second type UE are associated and configured.

[0106] Another configuration manner of the reference signal configuration for the first type UE and the second type UE may include: associated configuration.

[0107] In one embodiment, the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE are associated, resulting in two sets of reference signal configurations, one for the first type of UE and the other for the second type of UE. It is worth noting that, from a configuration perspective, these two sets of reference signal configurations are associated; and from a reference signal configuration perspective, these two sets of reference signal configurations have some of the same configuration information, or some of the reference signal configuration information is associated.

[0108] The reference signal configuration of the first type of UE and the reference signal configuration of the second type of UE are configured in an associated configuration manner. For the purpose of reducing signaling overhead, the reference signal configurations for the first type of UE and the second type of UE can be sent down together, and the same part of the reference signal configuration of the two types of UE can be indicated by a common bit, while the different part can be indicated by different bits.

[0109] Exemplarily, the configuration information in response to the reference signal includes: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, and associating and configuring the reference signal configuration for the first type UE and the reference signal configuration for the second type UE according to the first type UE and the second type UE includes:

[0110] In response to the reference signal configuration information including: a reference signal configuration for the first type of UE and a reference signal configuration for the second type of UE, a frequency range of the reference signal for the second type of UE is within a frequency range of the reference signal for the first type of UE;

[0111] and / or,

[0112] The configuration information in response to the reference signal includes: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, the second period of the reference signal for the second type UE is N times the first period of the reference signal for the first type UE, where N is a positive integer.

[0113] In one case, the frequency range for transmitting the reference signal for the second type of UE is within the frequency range for transmitting the reference signal for the first type of UE; the correlation of the configuration result obtained by this association configuration is reflected in the correlation of the frequency domain resources;

[0114] In another case, that is, the period of transmitting the reference signal for the second type UE is N times the period of the reference signal for the first type UE, the correlation in the configuration result of the association configuration is reflected in the transmission period of the reference signal.

[0115] The second period of the reference signal of the second type UE is N times the first period. In this way, the second type UE, whose processing capability is that of the first type UE, has more time to process the reference signal, thereby obtaining more accurate measurement of the reference signal and better realizing the first function and / or second function of the reference signal.

[0116] In some embodiments, the association configuration includes: a reference signal configuration for the first type of UE and a reference signal configuration for the second type of UE;

[0117] In response to the first type UE and the second type UE using the same downlink initial BWP, a reference signal configuration for the first type UE and a reference signal configuration for the second type UE are associated and configured.

[0118] Since the association configuration makes the association between the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE, reducing the BWP switching of at least one type of UE when receiving the reference signal, it is optional to associate the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE when the first type of UE and the second type of UE use the same downlink initial BWP.

[0119] In some embodiments, the change in the reference signal configuration of the first type UE is effective for the first type UE and the second type UE. Due to the correlation between the reference signal configuration of the first type UE and the reference signal configuration of the second type UE, and considering that the bandwidth supported by the first type UE is greater than the bandwidth supported by the second type UE, it can be considered that the change in the reference signal of the first type UE acts on the first type UE and the second type UE at the same time, that is, it is effective for the first type UE and the second type UE at the same time. It can be understood here that the first type UE and the second type UE need to update the reference signal configuration synchronously. For example, if the first type UE changes the frequency range of reference signal transmission, the second type UE will also change the frequency range of reference signal transmission synchronously. For another example, if the first type UE changes the period of the reference signal, the second type UE will still change the period of the reference signal synchronously with the first type UE based on the multiple relationship of N times.

[0120] In another embodiment, in the scenario of reference signal associated configuration, there may be only one change in the reference signal configuration for the first type UE and the second type UE, namely a joint change; and this joint change will take effect for both the first type UE and the second type UE.

[0121] In another embodiment, in the scenario of reference signal associated configuration, the change of the reference signal configuration for the first type UE and the second type UE may include a separate change in addition to the above-mentioned joint change. This separate change is applied to at least the second type UE. For example, the change of the reference signal configuration for the second type UE is effective for the second type UE. It can be understood that the change of the reference signal configuration for the second type UE is only effective for the second type UE, but not for the first type UE. If the base station sends the reference signal configuration for the second type UE, the first type UE will continue to maintain the original reference signal configuration after receiving it, and the second type UE will update the reference signal configuration of the second type UE based on the change after receiving the change.

[0122] In one embodiment, the availability indication of the reference signal for the first type UE is valid for the first type UE and the second type UE; or, the availability indication of the reference signal for the second type UE is valid for the second type UE.

[0123] In the associated configuration mode, due to the association between the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE, and the frequency range of the reference signal transmission defined by the reference signal configuration of the second type of UE is within the frequency range of the reference signal configuration for the first type of UE, and the base station releases a certain resource will release it as a whole. Therefore, if the availability indication of the reference signal configuration for the first type of UE takes effect for the first type of UE, it also needs to take effect for the second type of UE due to the release of all resources.

[0124] Similarly, the availability configuration of the reference signal specifically for the second type UE may be effective only for the second type UE, but not for the first type UE.

[0125] In one embodiment, configuring the reference signal configuration information according to the user equipment UE type includes:

[0126] In response to the reference signal configuration information, including: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, the reference signal configuration for the first type UE and the reference signal configuration for the second type UE are configured respectively.

[0127] In another embodiment, the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE may be configured separately. In this case, the reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE need to be configured separately according to the first type of UE and the second type of UE.

[0128] The reference signal configuration for the first type UE and the reference signal configuration for the second type UE are configured separately, and the configuration manner adopted is: separate configuration or separate configuration.

[0129] Configuring the reference signal configurations for the first type UE and the second type UE separately in this manner is equivalent to configuring the reference signal configuration for the first type UE based entirely on the characteristics of the first type UE, and configuring the reference signal configuration for the second type UE based entirely on the characteristics of the second type UE. Thus, by separately configuring the reference signal configurations for the first type UE and the second type UE in this manner, the most appropriate reference signal configurations for the current first type UE and second type UE can be configured, and the reference signal configurations of the first type UE and the second type UE can be scheduled with the greatest possible flexibility.

[0130] In some embodiments, the separately configuring the reference signal configuration for the first type UE and the reference signal configuration for the second type UE includes at least one of the following:

[0131] configuring a frequency range of a reference signal of the first type UE according to a bandwidth supported by the first type UE; and configuring a frequency range of a reference signal of the second type UE according to a bandwidth supported by the second type UE;

[0132] respectively configuring a period of a reference signal for the first type of UE and a period of a reference signal for the second type of UE;

[0133] According to the time domain offset supported by the first type UE, configure the time domain offset of the reference signal of the first type UE in the time domain and the paging occasion PO; according to the time domain offset supported by the second type UE, configure the time domain offset of the reference signal of the second type UE in the time domain and the PO.

[0134] The reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE are configured separately, in which case the first type of UE and the second type of UE can receive the reference signal at frequency domain positions that are completely non-overlapping or partially overlapping. The period of the reference signal configured for the first type of UE and the period of the reference signal configuration for the second type of UE are different, and may include:

[0135] The period of the reference signal for the first type UE is smaller than the period of the reference signal for the second type UE; thus, the second type UE can obtain more reference signals in a shorter time, thereby realizing corresponding functions and saving power consumption of the second type UE.

[0136] In some embodiments, a time domain offset between the reference signal and the PO for the first type of UE is smaller than a time domain offset between the reference signal and the PO for the second type of UE. If the time offset between the first type of UE and the PO is larger, the second type of UE has sufficient time to process the reference signal and the received PO, thereby reducing the backlog of signals to be decoded.

[0137] The separate configuration method can be used in situations where the downlink initial BWPs of the first type UE and the second type UE are the same or different.

[0138] In some embodiments, the S110 may include:

[0139] In response to different initial downlink BWPs of the first type UE and the second type UE, a reference signal configuration for the first type UE and a reference signal configuration for the second type UE are configured respectively.

[0140] In some embodiments, the change in the reference signal configuration for the first type of UE is effective for the first type of UE;

[0141] The change in the reference signal configuration for the second type UE takes effect for the second type UE.

[0142] Since the reference signals of the first type UE and the second type UE are configured independently in the separate configuration mode, the reference signal configuration of the first type UE and the reference signal configuration of the second type UE are both configured separately, so the corresponding reference signal configuration changes can be issued separately.

[0143] In some embodiments, the reference signal availability indication for the first type of UE is effective for the first type of UE; and the reference signal availability indication for the second type of UE is effective for the second type of UE. The reference signal configurations of the two types of UE are independently configured, so the availability indications are set separately and are effective for the corresponding types of UEs respectively.

[0144] In one embodiment, Figure 3 As shown, the method further includes:

[0145] S100: receiving auxiliary information;

[0146] The S110 may include:

[0147] Configuration information of the reference signal is configured according to the UE type and the auxiliary information.

[0148] In some embodiments, the UE reports auxiliary information to the base station for determining the configuration information of the reference signal. If the base station receives the auxiliary information reported by the UE, it will configure the configuration information of the reference signal for the UE of that type based on the UE type and the auxiliary information.

[0149] In some embodiments, the auxiliary information may include: a reference signal configuration recommended by the UE, or information related to the UE type and / or UE capabilities reported by the UE, so that the base station can configure the reference signal configuration of the UE type according to the characteristics of the UE type.

[0150] In some cases, the base station may not receive the auxiliary information reported by the UE, or may not need to receive the auxiliary information from the UE. For example, if the base station knows according to the protocol that the reference signal can be used or must be used for the UE in the non-connected state, it is not necessary to use the auxiliary information to determine whether the UE supports the use of the reference signal in the non-connected state.

[0151] For example, if the protocol specifies that the reference signal is used for UEs in an idle state or a non-connected state, the network side may not receive auxiliary information from the UE.

[0152] Alternatively, if the protocol stipulates that reference signals are mandatory for UEs in idle or inactive states, the base station may at least not receive auxiliary information from the UE side indicating whether the UE supports the use of reference signals in idle or inactive states.

[0153] In one embodiment, the auxiliary information indicates at least one of the following:

[0154] whether the UE supports use of a reference signal by the UE in an idle state and / or an inactive state, exemplarily, whether the UE supports time-frequency domain synchronization with a base station based on the reference signal in the idle state and / or inactive state;

[0155] The time domain offset between the reference signal and PO supported by the UE.

[0156] In one embodiment, if the protocol stipulates that the reference signal is optional for UEs in idle or inactive states; or if the protocol does not explicitly stipulate that the reference signal can be used for UEs in idle or inactive states, the base station may need to determine whether the reference signal can be used for UEs in idle or inactive states through the received auxiliary information.

[0157] In some embodiments, the receiving auxiliary information includes:

[0158] In response to a protocol not specifying that the reference signal is used for a UE in an idle state or an inactive state, receiving assistance information;

[0159] or,

[0160] In response to the protocol not stipulating that the function of using the reference signal for UE in idle state or inactive state is a mandatory function, auxiliary information is received.

[0161] In some embodiments, the auxiliary information is carried in a UE capability message and reported.

[0162] The UE capability message may be any message for the UE to report the UE capability, for example, a dedicated message for reporting the UE capability.

[0163] In one embodiment, the UE capability message includes but is not limited to: UE radio paging message (UE-RadioPagingInfo). Of course, this is only an example of the UE capability message, and the specific implementation is not limited thereto.

[0164] In the embodiments of the present disclosure, changes to the reference signal configuration for the first category of UEs and / or the second category of UEs may be carried in a change message sent by the base station. The change message may be various physical layer messages and / or higher layer messages. For example, the change message carrying the change to the reference signal configuration for the first category of UEs and / or the second category of UEs may be an RRC message.

[0165] like Figure 4 As shown, an embodiment of the present disclosure provides an information processing method, which is applied to a UE, and the method includes:

[0166] S210: Receive configuration information of a reference signal configured according to a UE type, wherein the reference signal includes at least one of the following: a TRS; a CSI-RS.

[0167] The embodiments of the present disclosure are applied to a UE, and the UE may be a first type UE and / or a second type UE.

[0168] The UE receives the configuration information, then receives / monitors the reference signal according to the configuration information, and then performs the first function and / or the second function based on the received reference signal.

[0169] In the embodiment of the present disclosure, the UE that executes the information processing method may be a UE in any state.

[0170] After receiving the configuration information, the UE may use the reference signal configured by the configuration information for a non-connected state of the UE; the non-connected state UE may be an idle state UE or an inactive state UE.

[0171] The configuration information of the reference signal is determined according to the UE type. Thus, the UE receives or monitors the reference signal according to the configuration information, which can satisfy the UE's execution of the aforementioned first and second functions while having the characteristic of low power consumption.

[0172] In one embodiment, the reference signal can be used for time-frequency domain synchronization between an idle or inactive UE and a base station; and / or, the reference signal can be used for radio resource management RRM measurement of an idle or inactive UE;

[0173] And / or, the reference signal can be used for AGC of a UE in an idle state or an inactive state.

[0174] In one embodiment, the UE types include at least: a first type UE; a second type UE; wherein the bandwidth supported by the first type UE is greater than the bandwidth of the second type UE.

[0175] The UE currently receiving the configuration information may be the first type UE or the second type UE; however, the UE type may include the first type UE and the second type UE.

[0176] The first type UE here may be an eMBB UE; the second type UE may be a Redcap UE.

[0177] In one embodiment, the configuration information of the reference signal is further used for phase tracking and / or acquiring channel state information of a UE in a connected state; the UE in the connected state includes: the first type UE in the connected state and / or the second type UE in the connected state;

[0178] or,

[0179] The configuration information of the reference signal for the second type of UE is not used for phase tracking and / or obtaining channel state information of the UE in the connected state.

[0180] In one embodiment, the first type UE is an enhanced mobile broadband eMBB UE;

[0181] and / or,

[0182] The second type of UE is a reduced capability Redcap UE.

[0183] In one embodiment, the reference signal configuration information is used for the first type UE and the second type UE in a connected state;

[0184] or,

[0185] The reference signal configuration information is used for the first type of UE in a connected state;

[0186] or,

[0187] The configuration information of the reference signal is used for the second type UE in the connected state.

[0188] In the embodiment of the present disclosure, the configuration information has multiple configuration methods, and three optional methods are provided below:

[0189] Mode 1: Common configuration or the same configuration, that is, for the first category UE and the second category UE, the same set of reference signal configurations are configured, and the set of reference signal configurations is shared by the first category UE and the second category UE.

[0190] Method 2:

[0191] Associated configuration: For the reference signal configuration of the first type of UE and the second type of UE, two sets of reference signal configurations will be configured, but these two sets of reference signal configurations are associated;

[0192] Method 3:

[0193] Separate configuration or separate configuration, that is, two sets of reference signal configurations are separately configured for the first type of UE and the second type of UE respectively; the two sets of reference signal configurations can be associated or unassociated.

[0194] Exemplarily, with respect to the association configuration, in one embodiment, the configuration information of the reference signal includes:

[0195] The first type UE and the second type UE share a common set of reference signal configurations.

[0196] In one embodiment, in response to the first type UE and the second type UE sharing the same BWP, the first type UE and the second type UE share a set of the reference signal configurations.

[0197] In one embodiment, in response to the first type UE and the second type UE sharing a set of reference signal configurations, the configuration information is determined based on the second type UE;

[0198] or,

[0199] In response to the first type UE and the second type UE sharing a set of reference signal configurations, the configuration information is determined based on the first type UE, wherein the configuration information of the reference signal is used for the second type UE to select a portion of the bandwidth supported by the second type UE within the bandwidth range of the reference signal to monitor the reference signal.

[0200] If the first type of UE and the second type of UE share a set of reference signal configurations, and if the set of reference signal configurations is configured based on the second type of UE, then the reference signal can be successfully monitored by the second type of UE with weaker UE capability, and obviously can also be successfully monitored by the first type of UE. Exemplarily, the configuration information is configured based on the bandwidth supported by the second type of UE, or the configuration information is determined based on the frequency domain offset between the reference signal supported by the second type of UE and the center frequency of the SSB, or, for the purpose of power consumption saving, the time offset between the reference signal supported by the UE and the PO.

[0201] At this time, once the first type UE and the second type UE receive the configuration information, they can monitor the reference signal according to the set of reference signal configurations included in the configuration information.

[0202] If the set of reference signal configurations included in the configuration information is configured according to the first type of UE, illustratively, the set of reference signal configurations is determined according to the bandwidth supported by the first type of UE.

[0203] At this time, if the UE currently receiving the configuration information is the second type of UE, when the second type of UE monitors the reference signal according to the configuration information, it first selects part of the bandwidth supported by the second type of UE within the frequency range based on the frequency range of the reference signal transmission, and then monitors the reference signal on the selected bandwidth.

[0204] In summary, in the embodiments of the present disclosure, both the first category UE and the second category UE share a common reference signal configuration, but the reference signal configuration takes the UE type into consideration.

[0205] In some embodiments,

[0206] In response to the first type UE and the second type UE sharing a set of reference signal configurations, the change in the reference signal configuration information takes effect for the first type UE and the second type UE.

[0207] Since the first type of UE and the second type of UE share a set of reference signal configurations, changes to the set of reference signal configurations are effective for both the first type of UE and the second type of UE.

[0208] In one embodiment, the reference signal availability indication is applied to both the first type UE and the second type UE.

[0209] If the configuration information carries a set of reference signal configurations shared by the first type of UE and the second type of UE, the availability indication of the reference signal will act on both the first type of UE and the second type of UE.

[0210] Exemplarily, in one embodiment, for the association configuration, the configuration information of the reference signal includes:

[0211] a reference signal configuration for the first type of UE and the reference signal configuration for the second type of UE;

[0212] The reference signal configuration for the first type UE is at least partially different from the reference signal configuration for the second type UE.

[0213] Since the configuration is associated, the configuration information received by the UE from the base station will carry two sets of associated reference signal configurations for the first type of UE and the reference signal configurations for the second type of UE.

[0214] In one embodiment, the configuration information in response to the reference signal includes: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, and the configuration information is configured based on the type association between the first type UE and the second type UE.

[0215] In one embodiment, in response to the reference signal configuration information including: a reference signal configuration for the first type of UE and a reference signal configuration for the second type of UE, a frequency range of the reference signal for the second type of UE is within a frequency range of the reference signal for the first type of UE;

[0216] and / or,

[0217] The configuration information in response to the reference signal includes: a reference signal configuration for the first type UE and a reference signal configuration for the second type UE, the second period of the reference signal for the second type UE is N times the first period of the reference signal for the first type UE, where N is a positive integer.

[0218] In one embodiment, the change in the reference signal configuration for the first type of UE is effective for the first type of UE and the second type of UE;

[0219] or,

[0220] The change in the reference signal configuration for the second type UE takes effect for the second type UE.

[0221] With respect to the associated configuration, the reference signal configuration for the second category of UEs depends on the reference signal configuration for the first category of UEs. Therefore, changes to the reference signal configuration for the first category of UEs will affect the reference signal configuration for the second category of UEs. Therefore, changes to the reference signal configuration for the first category of UEs are made for both the first category of UEs and the second category of UEs. If the UE currently receiving the configuration information and the change to the reference signal configuration for the first category of UEs is a first category of UEs, the change is performed. If the UE currently receiving the configuration information and the change to the reference signal configuration for the first category of UEs is a second category of UEs, the reference signal configuration for the second category of UEs is adaptively changed based on the change and the association between the reference signal configuration for the first category of UEs and the reference signal configuration for the second category of UEs. For example, the association between the reference signal configuration for the first category of UEs and the reference signal configuration for the second category of UEs can be reflected in the relationship between the frequency range and / or period of reference signal transmission configured for the reference signal configuration for the first category of UEs and the reference signal configuration for the second category of UEs.

[0222] If the reference signal configuration is only for the second type of UE, it can be effective for the second type of UE alone, but not for the first type of UE; at this time, if the first type of UE does not receive the change, the reference signal configuration of the first type of UE can maintain the currently effective configuration.

[0223] In some embodiments, the availability indication of the reference signal for the first type of UE is valid for the first type of UE and the second type of UE;

[0224] or,

[0225] The availability indication of the reference signal for the second type UE is effective for the second type UE.

[0226] Similarly, due to the associated configuration, the reference signal configuration of the second category UE depends on the reference signal configuration of the first category UE. The reference signal availability indication for the first category UE is effective for both the first category UE and the second category UE. However, the reference signal availability indication for the second category UE is effective only for the second category UE.

[0227] Exemplarily, for separate configuration or separate configuration, in some embodiments, in response to the configuration information of the reference signal, including: reference signal configuration for the first type UE and reference signal configuration for the second type UE, the configuration information is configured separately according to the types of the first type UE and the second type UE.

[0228] Since the preset reference configurations for the first category UE and the second category UE are configured separately, when configuring the reference signals for the first category UE and the second category UE respectively, the characteristics of the first category UE and / or the second category UE can be considered flexibly to the maximum extent.

[0229] Exemplarily, in some embodiments, the change in the reference signal configuration for the first type of UE takes effect for the first type of UE;

[0230] The change in the reference signal configuration for the second type UE takes effect for the second type UE.

[0231] Exemplarily, the availability indication of the reference signal for the first type of UE is effective for the first type of UE;

[0232] The availability indication of the reference signal for the second type UE is effective for the second type UE.

[0233] For example, Figure 5 As shown, the method further includes:

[0234] S200: Send auxiliary information; wherein, the auxiliary information is used for the base station to configure the configuration information of the reference signal.

[0235] The auxiliary information may carry any information required by the base station for configuring the reference signal.

[0236] In some embodiments, the auxiliary information indicates at least one of the following:

[0237] Whether the UE supports the use of reference signals by UEs in idle state and / or inactive state;

[0238] The time domain offset between the reference signal and PO supported by the UE.

[0239] In some embodiments, the S200 may include:

[0240] In response to the protocol not specifying that the reference signal is used for UEs in an idle state and / or an inactive state, sending auxiliary information;

[0241] or,

[0242] In response to the protocol not specifying that the reference signal is used for the UE in the idle state and / or the inactive state as a mandatory function, sending auxiliary information. Exemplarily, in response to the protocol not specifying that the reference signal is used for the UE in the idle state and / or the inactive state, sending auxiliary information includes:

[0243] In response to the protocol not specifying that the reference signal is used for UEs in idle state and / or inactive state, auxiliary information indicating that the reference signal is used for UEs in idle state and / or inactive state is sent.

[0244] Exemplarily, in response to the protocol not stipulating that the reference signal is used as a mandatory function for UEs in an idle state and / or an inactive state, sending the auxiliary information may include:

[0245] In response to the protocol not stipulating that using the reference signal for UEs in idle state and / or inactive state is a mandatory function, auxiliary information indicating that the reference signal is used for UEs in idle state and / or inactive state is sent.

[0246] In one embodiment, the auxiliary information is carried in a UE capability message.

[0247] Exemplarily, the UE capability information includes but is not limited to: UE wireless paging message.

[0248] In one embodiment, the method further comprises:

[0249] The reference signal is received by frequency hopping according to the configuration information.

[0250] If the current working BWP of the UE is far away from the frequency domain position of the reference signal, the UE needs to perform frequency hopping to receive the reference signal.

[0251] The UE's current working BWP includes but is not limited to a downlink initial BWP and / or an activated BWP.

[0252] In some embodiments, the frequency hopping and receiving the reference signal according to the configuration information includes:

[0253] In response to a distance between the frequency domain position of the reference signal and the center frequency point of the SSB being greater than a preset value, the reference signal is received by frequency hopping according to the configuration information.

[0254] For Redcap UE, more SSBs may be needed for synchronization, so the use of TRS / CSI-RS is more critical for Redcap UE due to its bandwidth limitation.

[0255] For Redcap UEs, the minimum supported terminal bandwidths in Frequency Band 1 (FR)1 / FR2 are 20 MHz and 100 MHz, respectively. However, eMBB UEs support bandwidths greater than 100 MHz. Therefore, the TRS / CSI-RS configured for eMBB UEs may not be suitable for Redcap UEs. In a network with both eMBB UEs and Redcap UEs, the TRS / CSI-RS used by Redcap UEs is a key consideration in coexistence scenarios. This article provides a method for configuring TRS / CSI-RS for Redcap UEs.

[0256] The network configures additional TRS / CSI-RS configuration information for specific types of UEs. The reference signal corresponding to the configuration information is used for UEs in idle / inactive states.

[0257] As an embodiment, the specific type of UE may include eMBB UE (first type UE) and / or Redcap UE (second type UE), etc.

[0258] It can be understood that the network configures additional TRS / CSI-RS configuration information for the first type UE and the second type UE, and the set of connected UEs for which the additional TRS / CSI-RS is provided may be the same or different.

[0259] The TRS / CSI-RS configuration information corresponds to a set of connected UEs, which can be of various types, as follows:

[0260] Case 1: additional TRS / CSI-RS configuration information is configured for first type UE and second type UE, and the connected UE sets providing additional TRS / CSI-RS are first type connected UE and second type connected UE respectively.

[0261] Case 2: additional TRS / CSI-RS configuration information is configured for first type UE and second type UE, and the set of connected UEs that provide additional TRS / CSI-RS are collectively second type connected UEs.

[0262] Case 3: additional TRS / CSI-RS configuration information is configured for first type UE and second type UE, and the set of connected UEs providing additional TRS / CSI-RS are all first type connected UEs.

[0263] As an embodiment, the TRS / CSI-RS configuration information configured for the second type of UE does not need to rely on the TRS / CSI-RS sharing provided by the connected UE, that is, it can be configured separately (for the convenience of the agent, the second type of terminal synchronization is relatively slow, so the network can provide an additional set of separate TRS / CSI-RS, that is, it does not need to rely on the TRS / CSI-RS sharing provided by the connected UE).

[0264] It is worth noting that the set of connected UEs providing additional TRS / CSI-RS in the cell changes from one to none, for example, if the UE is handed over or released, which will cause the availability of TRS / CSI-RS to change from available to unavailable.

[0265] Method 1: The network configures the same set of additional TRS / CSI-RS reference signal configurations for the first type UE and the second type UE, or configures a separate set of additional TRS / CSI-RS reference signal configurations.

[0266] It can be understood that there are two configuration implementations for the network to configure the same set of additional TRS / CSI-RS reference signal configurations for the first type UE and the second type UE:

[0267] Method 1: The parameters of the configured TRS / CSI-RS need to be restricted, such as limiting them to the bandwidth supported by the second type of UE. For example, the bandwidth supported by Redcap UE in FR1 and FR2 is 20M; the bandwidth supported by Embb UE in FR1 and FR2 is 100M.

[0268] Mode 2: There is no need to restrict the bandwidth parameters of the configured TRS / CSI-RS to the bandwidth range supported by the second type of UE. In this case, the second type of UE will directly use the TRS / CSI-RS within its bandwidth support range for auxiliary synchronization operation.

[0269] At this time, the connected UE set for which additional TRS / CSI-RS is provided may be the UE set provided in case 2 or case 3.

[0270] At this time, the TRS / CSI-RS configuration and / or availability change will take effect for both the first type of UE and the second type of UE; that is, the TRS / CSI-RS configuration change and / or availability change notified by the network will cause both types of UE to re-acquire the new configuration and / or availability indication;

[0271] Method 2: The TRS / CSI-RS configuration information configured for the second type of UE reuses some of the TRS / CSI-RS configuration information configured for the first type of UE, while some of the configuration information may be different for the first type of UE. That is, some of the configuration information is the same, and this method can save signaling overhead.

[0272] As an embodiment: the frequency range configured for the first type of UE is 100M bandwidth, and the frequency range configured for the second type of UE is 20M bandwidth, which is intercepted from the 100M bandwidth;

[0273] As an embodiment: the cycle is configured, the cycle configured for the first type UE is cycle 1, and the cycle configured for the first type UE is cycle 2 which is a multiple N of cycle 1; that is, one resource in N cycles is used by the second type UE;

[0274] At this time, the set of UEs in the connected state that provide additional TRS / CSI-RS is the same as the set of UEs provided in the aforementioned case 1.

[0275] At this time, the configuration information and / or availability change of TRS / CSI-RS will be effective for the first type of UE and also for the second type of UE;

[0276] At this time, the configuration information and / or availability change of the TRS / CSI-RS as a subset will only take effect for the second type of UE.

[0277] For example, because the TRS / CSI-RS resources used by the redcap UE are a subset of the TRS / CSI-RS resources of the eMBB UE, any change in the configuration or availability of the TRS / CSI-RS of the eMBB UE will inevitably affect the redcap UE. Alternatively, the eMBB configuration or availability status may remain unchanged, and only the configuration and availability of some resources used by the redcap UE may be changed.

[0278] It can be understood that TRS / CSI-RS resource availability indication is set up for the second type UE and the first type UE respectively, and the identifier of the availability indication may include: flag1 and flag2. If flag1 is unavailable, both types of UEs consider the resource unavailable; flag2 only applies to Redcap UE.

[0279] Mode 3: The network configures different additional TRS / CSI-RS configuration information for the first type UE and the second type UE.

[0280] As an embodiment: the frequency range configured for the first type UE is 20M bandwidth, while the frequency range configured for the second type UE is 100M bandwidth.

[0281] As an embodiment: the cycle is configured as cycle 2 for the second type UE, and is configured as cycle 1 for the first type UE;

[0282] Furthermore, cycle2 is larger than cycle1; that is, the period of TRS / CSI-RS of RedcapUE is more sparse;

[0283] As an embodiment: offset, configured for the second type UE is offset2, and configured for the first type UE is offset1;

[0284] Furthermore, where offset2 is greater than offset1;

[0285] The network can configure the same initial BWP or different initial BWPs for the TRS / CSI-RS end of the first type UE and the second type UE; further: if the initial BWPs are separated, separate TRS / CSI-RS configurations are required.

[0286] At this time, the connected UE set for which additional TRS / CSI-RS is provided may be the UE set in Case 1.

[0287] At this time, the configuration information and / or availability change of TRS / CSI-RS will take effect for the first type UE and the second type UE respectively;

[0288] That is, the network notifies that the configuration change and / or availability change for a certain set of configured TRS / CSI-RS will only cause the specific type of UE to re-acquire the new configuration and / or availability indication.

[0289] As an embodiment, a certain type of UE may need frequency hopping reception when using additional TRS / CSI-RS.

[0290] For example: If the configured TRS / CSI-RS frequency domain position is far away from the SSB center frequency.

[0291] As an embodiment, a specific type of UE may provide the following auxiliary information to the network:

[0292] Does the UE support the use of additional TRS / CSI-RS in idle / inactive state?

[0293] As an embodiment, whether to support this feature can be agreed in advance by protocol;

[0294] As an embodiment, it is mandatory for Redcap UE to support this feature. In this case, the network defaults to supporting this feature for this type of terminal.

[0295] The minimum offset value between TRS / CSI-RS and PO supported by the UE is related to the terminal type.

[0296] As an embodiment, the minimum offset value supported by the Redcap UE shall not be shorter than the minimum offset value supported by the eMBB type terminal;

[0297] It is worth noting that the auxiliary information reported by the terminal can be placed in the existing UE-RadioPagingInfo and placed in the UE capability and reported to the base station.

[0298] For method 1 and / or method 2: that is, when a set of resources is configured, the network can configure the offset according to the larger reported offset value.

[0299] For method 3, the offset can be configured according to the respective reported offsets of eMBBUE and RedcapUE.

[0300] Specific type of UE Specific type of UE eMBB UE ERedcap UE in connected state UE in connected state UE in connected state UE in connected state UE availability indication in connected state UE in connected state UE availability indication in connected state Specific type of UE Redcap UE ERedcap UE.
