Fig. 1 is a schematic flow chart of a reference signal receiving method according to an embodiment of the present disclosure. The reference signal receiving method shown in this embodiment may be executed by a terminal, where the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may serve as a user equipment to communicate with a base station, including but not limited to a base station in a 4G, 5G, 6G, etc. communication system.
As shown in fig. 1, the reference signal receiving method may include the steps of:
in step S101, determining time-frequency resource information of a reference signal received in a non-connected state, wherein the reference signal is different from a synchronization signal block SSB;
in step S102, the reference signal is received in a non-connected state according to the time-frequency resource information.
In one embodiment, the unconnected state may be a free idle state or an inactive state.
In an embodiment, the terminal may determine time-frequency resource information of the reference signal received in the non-connected state, and then, after entering the non-connected state, the terminal may receive the reference signal according to the time-frequency resource information. The Reference Signal may be referred to as an additional Reference Signal RS (Reference Signal), which is a Reference Signal different from SSB.
After receiving the reference signal, the terminal may perform time-frequency synchronization at least using the reference, for example, may perform time-frequency tracking T/F tracking using the reference signal. Accordingly, the terminal may receive a reference signal other than the SSB in the unconnected state, and may further perform an action using the received reference signal, for example, perform time-frequency synchronization when receiving MBS (Multi-cast/Broadcast service) data, rather than performing an action only according to the SSB, thereby improving flexibility of performing an action according to the reference signal in the unconnected state.
For example, the modulation level of the reference signal is higher than that of the SSB, and after the terminal receives the reference signal according to the time-frequency resource in the non-connected state, the terminal may perform time-frequency synchronization according to the reference signal. In one embodiment, the time-frequency resource information includes at least one of: time-frequency pattern, period, time-domain offset, frequency-domain position.
It should be noted that, in addition to the above contents, the time-frequency resource information may also include other contents, for example, information of a port used by the reference signal, information of a bandwidth portion bwp (bandwidth part) where the reference signal is located, and the like, according to needs.
Fig. 2 is a schematic diagram illustrating a timeslot structure according to an embodiment of the disclosure.
For example, the terminal-residing cell is a TDD (Time-division Duplex) cell, and the network side configures TDD uplink and downlink configuration UL DL configuration of the cell through SIB1, where the TDD UL DL configuration is a single period, the timeslot structure is DDSUU, and Sub-Carrier Spacing SCS (Sub-Carrier Spacing) is 15 kHz. As shown in fig. 2, the structure of the uplink and downlink slots of the special slot is 7D 3F 4U, that is, the special slot includes 7 downlink symbols (e.g., OFDM symbols), 3 variable flexible symbols, and 4 uplink symbols.
It should be understood that the embodiments of the present disclosure may also be applicable to a case where the terminal resides in a frequency division multiplexing FDD cell, and are not described herein again.
Fig. 3 is a schematic diagram illustrating a time-frequency pattern of a reference signal according to an embodiment of the disclosure.
In one embodiment, the reference signal may be transmitted multiple times in one RS burst, and one RS burst may include one or more slots, each slot including two reference signal samples RS sample. For example, as shown in fig. 3, taking an RS burst containing two slots as an example, each slot may contain 2 RS samples, and adjacent RS samples in the slot are separated by 4 symbols in the time domain.
Fig. 4 is a schematic diagram illustrating a relationship between a reference signal and a slot structure according to an embodiment of the disclosure.
In one embodiment, for example, if the period of the reference signal is 10 ms, for example, 1 slot corresponds to 1 ms, the time-domain offset is 0, and the time-frequency pattern is as shown in fig. 3, then the position of the terminal in the slot structure can be as shown in fig. 4. That is, every 10 slots, there is an RS burst in the downlink slot, which includes an RS sample.
Fig. 5 is a schematic flow chart diagram illustrating another reference signal receiving method according to an embodiment of the present disclosure. As shown in fig. 5, the method further comprises:
in step S501, at least one of the following operations is performed according to the reference signal:
the automatic gain control solves the problems of AGC setting, time-frequency tracking T/F tracking, interference measurement, channel measurement, signal-to-interference-plus-noise ratio SINR measurement and reference signal received power RSRP measurement.
In an embodiment, after the terminal receives the reference signal in the non-connected state, time-frequency synchronization, such as time-frequency tracking T/F tracking, may be performed based on the reference signal. Besides performing time-frequency synchronization, other operations, such as AGC setting, interference measurement, channel measurement, signal-to-interference-plus-noise ratio SINR measurement, reference signal received power RSRP measurement, etc., may be performed based on the reference signal, and may be specifically set as required.
The manner in which the terminal determines the time-frequency resource for receiving the reference signal in the non-connected state may be flexibly set, and the following mainly illustrates three manners.
Fig. 6 is a schematic flow chart diagram illustrating yet another reference signal receiving method according to an embodiment of the present disclosure. As shown in fig. 6, the determining time-frequency resource information for receiving the reference signal in the non-connected state includes:
in step S601, the time-frequency resource information is determined according to a predetermined rule.
In one embodiment, the protocol may agree on a rule or the base station and the terminal may negotiate an agreed rule, and the terminal may determine the time-frequency resource information according to the rule.
In this case, since the unspecified terminal in the cell may determine the rule and then receive the reference signal, the reference signal may be a reference signal cell-specific RS for the cell, and the time-frequency resource information determined by the terminal may be applicable to the specific cell.
Fig. 7 is a schematic flow chart diagram illustrating yet another reference signal receiving method according to an embodiment of the present disclosure. As shown in fig. 7, the determining time-frequency resource information for receiving the reference signal in the non-connected state includes:
in step S701, the time-frequency resource information is determined according to a system information block SIB.
In an embodiment, the base station may broadcast the time-frequency resource information through a system information block, for example, SIB1, and the terminal may determine the time-frequency resource information according to the received system information block.
In this case, since the system information block is sent in a broadcast manner, all unspecified terminals in the cell may receive the system information block broadcast by the base station corresponding to the cell, and further receive the reference signal, where the reference signal may be a reference signal cell-specific RS for the cell, and the time-frequency resource information determined by the terminal may be applicable to the specific cell.
Fig. 8 is a schematic flow chart diagram illustrating yet another reference signal receiving method according to an embodiment of the present disclosure. As shown in fig. 8, the determining time-frequency resource information for receiving the reference signal in the non-connected state includes:
in step S801, the time-frequency resource information is determined according to the downlink control information DCI.
In an embodiment, the base station may carry the time-frequency resource information through the DCI, and the terminal may determine the time-frequency resource information according to the received DCI.
In this case, since the DCI is sent in a unicast or multicast manner, the terminal in communication with the base station in the cell may receive the DCI sent by the base station corresponding to the cell, and further receive the reference signal, where the reference signal may be a reference signal group-specific RS for a terminal group, and the time-frequency resource information in the DCI may be applicable to each terminal in the group. Certainly, the time-frequency resource information carried in the DCI sent by the base station for different terminals may also be different, and may be specifically set according to needs.
Fig. 9 is a schematic flow chart diagram illustrating yet another reference signal receiving method according to an embodiment of the present disclosure. As shown in fig. 9, the determining time-frequency resource information for receiving the reference signal in the non-connected state includes:
in step S901, determining an association relationship between at least one reference signal and time-frequency resource information according to a predetermined rule and/or SIB;
in step S902, a target reference signal and target time-frequency resource information corresponding to the target reference signal are determined in the association relationship according to the DCI.
In one embodiment, the type of the reference signal comprises at least one of: semi-persistent reference signal semi-persistent RS, aperiodic reference signal aperiodic RS.
In one embodiment, the protocol may agree on a rule or the base station and the terminal may negotiate an agree on a rule, and the rule may specify an association relationship of the at least one reference signal and the time-frequency resource information, which is known to both the terminal and the base station.
For example, the association relationship is an association relationship list RS list between the identifier of the reference signal and the time-frequency resource information, which may be shown in table 1 below:
| reference signal identification | Time-frequency resource information |
| #0 | Configuration#0 |
| #1 | |
| #2 | Configuration#2 |
| … | … |
| #n | Configuration#n |
TABLE 1
It is understood that each of the elements of table 1 are present independently and are exemplary listed in the same table, but do not mean that all of the elements in the table must be present according to the presentation in the table at the same time. The value of each element is independent of any other element value in table 1. Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 1 are independent embodiments.
The base station can subsequently determine that the terminal is required to receive the reference signal based on the target time-frequency resource information according to the requirement, further determine the target reference signal corresponding to the target time-frequency resource information based on the RS list, and then send the identifier of the target reference signal to the terminal through the DCI. After receiving the DCI, the terminal may determine corresponding target time-frequency resource information in the RS list according to the identifier of the target reference signal, and then receive the target reference signal based on the target time-frequency resource information in the non-connected state.
For example, the base station determines that the terminal needs to receive the reference signal based on the target time domain resource information Configuration # 1, and may determine that the identifier of the target reference signal corresponding to Configuration # 1 is #1 based on table 1, and then may send the reference signal to the terminal through the DCI carrying indication # 1. After receiving the DCI, the terminal may determine, according to the identifier # 1 therein, that the corresponding target time domain resource information is Configuration # 1 in the representation 1, and further may receive a target reference signal according to the Configuration # 1 in a non-connected state.
For example, according to Configuration # 1, a time-frequency pattern of the reference signal, a trigger offset triggerring offset, and the like can be determined, where the trigger offset is an offset between a slot in which the DCI is located and a slot in which the reference signal is located.
In an embodiment, the base station may indicate an association relationship between at least one reference signal and time-frequency resource information through an SIB, and the association relationship may be determined after the terminal receives the SIB.
For example, the association relationship is an association relationship list RS list between the identifier of the reference signal and the time-frequency resource information. The base station can subsequently determine target time-frequency resource information according to needs, further determine a target reference signal corresponding to the target time-frequency resource information based on the RS list, and then send the identifier of the target reference signal to the terminal through the DCI. After receiving the DCI, the terminal may determine corresponding target time-frequency resource information in the RS list according to the identifier of the target reference signal, and then receive the target reference signal based on the target time-frequency resource information in the non-connected state.
In one embodiment, the DCI is scrambled by one of the following radio network temporary identities RNTI:
SI-RNTI、P-RNTI、RA-RNTI、G-RNTI。
in one embodiment, in the case that the DCI is scrambled by one of SI-RNTI, P-RNTI and RA-RNTI, the reference signal is determined to be received in a non-connected state according to reserved bits in the DCI, and/or the time-frequency resource information is determined.
In the case of scrambling the DCI by one of the SI-RNTI, the P-RNTI and the RA-RNTI, the format of the DCI may be DCI format 1_0 for which reserved bits exist. The base station may carry an indication in the reserved bits, which is used to indicate the terminal to receive the reference signal in the non-connected state, and may also be used to indicate the time-frequency resource information. After receiving the DCI, the terminal may trigger a non-connection-state reception reference signal according to the reserved bits therein, and may also determine the time-frequency resource information.
When the DCI is scrambled by the G-RNTI or other RNTIs, the format of the DCI may be set as needed, and for example, the format may be DCI format 1_0, DCI format 1_1, or DCI format 1_ 2.

In one embodiment, the unconnected state may be a free idle state or an inactive state.
In an embodiment, the terminal may determine time-frequency resource information of the reference signal received in the non-connected state, and then, after entering the non-connected state, the terminal may receive the reference signal according to the time-frequency resource information. The reference signal may be referred to as an additional reference signal, RS, which is a different reference signal than SSB.
After receiving the reference signal, the terminal may perform time-frequency synchronization at least using the reference, for example, may perform time-frequency tracking T/F tracking using the reference signal. Accordingly, the terminal may receive the reference signal other than the SSB in the unconnected state, and further may perform an action using the received reference signal, for example, perform time-frequency synchronization when receiving MBS data, without being limited to performing the action according to the SSB, which may improve flexibility of performing the action according to the reference signal in the unconnected state.
For example, the modulation level of the reference signal is higher than that of the SSB, and after the terminal receives the reference signal according to the time-frequency resource in the non-connected state, the terminal may perform time-frequency synchronization according to the reference signal.
In one embodiment, the time-frequency resource information includes at least one of: time-frequency pattern, period, time-domain offset, frequency-domain position.

In one embodiment, the protocol may agree on a rule or the base station and the terminal may negotiate an agreed rule, and the terminal may determine the time-frequency resource information according to the rule.
In this case, since the unspecified terminal in the cell may determine the rule and then receive the reference signal, the reference signal may be a reference signal cell-specific RS for the cell, and the time-frequency resource information determined by the terminal may be applicable to the specific cell.

In an embodiment, the base station may carry the time-frequency resource information through the DCI, and the terminal may determine the time-frequency resource information according to the received DCI.

Certainly, the time-frequency resource information carried in the DCI sent by the base station for different terminals may also be different, and may be specifically set according to needs.
In an embodiment, the terminal determines an association relationship between at least one reference signal and time-frequency resource information in advance, and the DCI is used to indicate a target reference signal in the association relationship.
