Fig. 2 is a flowchart illustrating a method for configuring a reference signal according to an exemplary embodiment, where as shown in fig. 2, the method for configuring a reference signal according to the embodiment of the present disclosure includes the following processing steps:
in step 201, a network device transmits a reference signal in at least one of a first location and a second location.
In an embodiment of the present disclosure, the first location may include a first time domain location and/or a first frequency domain location, and the second location may include a second time domain location and/or a second frequency domain location.
Wherein the first location is before the PO; the reference signal at the first location is located in the vicinity of the SSB, which takes into account that Radio Resource Management (RRM) of the communication system has a requirement for measurement of the SSB, which also meets the relevant requirements of the protocol. The first location may be located before or after the SSB.
The second location is located between the PDCCH and the PDSCH in the PO. Here, since the DCI is carried on the PDCCH and the specific paging message is carried on the PDSCH, the second location may be located between the DCI and the paging message of the UE. The UE may determine whether the PDSCH indicated by the DCI carries its paging message according to whether the scrambling code in the PDCCH is self-scrambling code, so as to determine whether to receive the PDSCH indicated by the DCI.
In this disclosure, when the network device determines that the communication parameter configured by the network device does not satisfy the preset communication condition, the reference signal is sent at both the first location and the second location. Here, the communication parameter of the network device may be a size of a coverage area, a connection condition of the coverage area with coverage areas of other network devices, whether buildings and the like exist in a current environment in which the network device is located to affect reception of wireless signals, and the like, that is, when a channel quality of an area covered by the network device is not good, the reference signal needs to be transmitted at both the first location and the second location. That is, when the coverage area of the network device is large and a weak coverage area exists or the weak coverage area is large, the reference signal is sent at both the first location and the second location. As an example, the reference signal is transmitted at both the first location and the second location, e.g., when the coverage area of the network device exceeds 1.5 km. Or, according to the signal transmitting capability of the network device in the communication system, when the coverage area exceeds the effective access range, the reference signal is transmitted at both the first position and the second position.
The network device determines that the communication parameters configured by the network device do not satisfy the preset communication conditions, such as network devices arranged in suburbs or rural areas with less population, and the like, and because the network device is sparsely arranged, the network device may possibly not satisfy the preset communication conditions. The network equipment determines that the communication parameters of the network equipment do not meet preset communication conditions, and can also determine the communication parameters through parameters such as the success rate of UE access, the call drop rate, the reported measurement signals and the like.
In the embodiment of the present disclosure, the preset communication conditions include that the distribution density of the network device is higher than a first set threshold, the coverage area range of the network device is lower than a second set threshold, the call drop rate of the UE at the edge of the cell is lower than a third set threshold, the handover success rate at the edge of the cell is higher than a fourth set threshold, and the like.
And when the network device transmits reference signals at both the first location and the second location, the reference signal transmitted at the first location may be used as a WUS. The UE may wake up based on the reference signal of the first location, and turn on a listening function of the SSB.
In the embodiment of the present disclosure, if the coverage area of the network device is large, a weak coverage area exists, or the weak coverage area is large, the reference signal may also be sent only at the first location, and at this time, the configuration of sending the reference signal at the first location and repeating the PO needs to be repeated.
And when the network equipment determines that the communication parameters configured by the network equipment meet preset communication conditions, only the reference signal is sent at the second position. That is, when the network devices are located more in some areas, the network construction is better, and the coverage cell signal is better, the reference signal may be sent only at the second location.
In the disclosed embodiment, when the network device determines that the reference signal is to be transmitted at both the first location and the second location, the first location is placed before an SSB; determining that the first location is to be located after the SSB only when the first location carries the reference signal; or
The network device determining to place the first location after an SSB when the reference signal is to be transmitted at both the first location and the second location; determining that the first location is to precede the SSB only when the first location carries the reference signal.
Here, whether the network device sends the reference signal at the first position may be indicated by the carrying position where the reference signal is sent at the first position, so that the UE may determine whether the second position sends the reference signal according to the carrying position of the reference signal at the first position, so as to correspondingly listen to the reference signal according to an actual reference signal sending mechanism of the network device, thereby avoiding unnecessary energy consumption of the UE and saving electric energy of the UE. The above indication manner indicating whether the reference signal is transmitted from the second location by the reference signal before or after the SSB may be configured in the UE in advance, that is, the indication manner indicating whether the reference signal is transmitted from the second location by the reference signal before or after the SSB may be used as a part of a communication protocol.
In an embodiment of the present disclosure, when the network device determines to transmit the reference signal at both the first location and the second location, the first location is located in a first time domain; determining to place the first location in a second time domain only when the first location carries the reference signal; the first time domain and the second time domain are not coincident. Here, whether the UE transmits the reference signal at the second location may be informed by a bearer time domain of the first location. For example, when the reference signal of the first location is located on a first Orthogonal Frequency Division Multiplexing (OFDM) symbol before the SSB, the second location is instructed to transmit the reference signal, and when the reference signal of the first location is located on other OFDM symbols, the second location is instructed not to transmit the reference signal. That is, in the embodiment of the present disclosure, whether the reference signal is transmitted by the second location may be indicated by a bearer location of the reference signal near the SSB. Whether the second location transmits the reference signal may be indicated, for example, by an offset location between a location of a bearer of the reference signal in the vicinity of the SSB and the SSB. For example, when the carrying position of the reference signal near the SSB is within one OFDM symbol before and after the SSB, the second position is instructed to transmit the reference signal, and when the carrying position of the reference signal near the SSB is located on an OFDM symbol other than one OFDM symbol before and after the SSB, the second position is instructed not to transmit the reference signal.
In an embodiment of the present disclosure, the network device determines to repeat the configuration of the PO only when the first location carries the reference signal; determining that the configuration of POs is not to be repeated when the reference signals are determined to be transmitted at both the first location and the second location. That is, in the embodiment of the present disclosure, whether the reference signal is also transmitted at the second location may be indicated by whether there is a duplicate PO.
In an embodiment of the present disclosure, the reference signal includes at least one of: channel State Information-Reference Signal (CSI-RS), Tracking Reference Signal (TRS).
That is, in the embodiment of the present disclosure, the CSI-RS or the TRS may be transmitted at the first location, and the reference signal transmitted at the second location may also be the CSI-RS or the TRS.
Fig. 3 is a flowchart illustrating a method for receiving a reference signal according to an exemplary embodiment, where as shown in fig. 3, the method for receiving a reference signal according to the embodiment of the present disclosure includes the following processing steps:
in step 301, the UE receives a reference signal in at least one of a first location and a second location.
Wherein the first location may comprise a first time domain location and/or a first frequency domain location and the second location may comprise a second time domain location and/or a second frequency domain location
In an embodiment of the present disclosure, the first location is located before the PO; the reference signal at the first location is located in the vicinity of the SSB, which takes into account that Radio Resource Management (RRM) of the communication system has a requirement for measurement of the SSB, which also meets the relevant requirements of the protocol. The first location may be located before or after the SSB. And the second location is between the PDCCH and the PDSCH in the PO.
For example, the paging receiving process may include detecting a PDCCH from a corresponding search space of the PO, and then parsing DCI for paging, and if DCI is parsed, receiving a PDSCH according to the DCI, and demodulating a paging message; if the mark in the paging message is UE, initiating connection, otherwise continuing sleeping; if the DCI is not solved, the fact that no paging message exists in the current discontinuous reception DRX _ on period is shown.
In this embodiment of the present disclosure, after receiving the reference signal at the first location, the UE wakes up an SSB listening function of the UE. That is, when a network device transmits the reference signal at both the first location and the second location, the reference signal at the first location may be used as a WUS. The UE may determine whether to wake up the listening function of the SSB based on whether the reference signal is received in the vicinity of the SSB.
In an embodiment of the disclosure, the method further comprises: and the UE determines that the position for receiving the reference signals adjacent to the SSB is positioned before the SSB, receives other reference signals between the PDCCH and the PDSCH, and does not receive other reference signals otherwise.
As an implementation manner, in an embodiment of the present disclosure, the method further includes: and the UE determines that the position for receiving the reference signals adjacent to the SSB is positioned after the SSB, receives other reference signals between the PDCCH and the PDSCH, and does not receive other reference signals otherwise.
In the embodiment of the present disclosure, whether the network device transmits the reference signal at the first position may be indicated by a bearer position at which the reference signal is transmitted at the first position. And the UE determines whether the reference signal is sent by the second position according to the bearing position of the reference signal at the first position so as to correspondingly intercept the reference signal according to the actual reference signal sending mechanism of the network equipment, thereby avoiding unnecessary energy consumption of the UE and saving the electric energy of the UE. The above-mentioned indication manner that the reference signal is located before or after the SSB to indicate whether the reference signal is transmitted from the second location is configured in the UE in advance, and the UE determines whether the reference signal is carried between the PDCCH and the PDSCH based on the actually received carrying position of the reference signal near the SSB, so as to determine whether the reference signal is sensed between the PDCCH and the PDSCH.
In an embodiment of the disclosure, the method further comprises: and when the UE receives the reference signal in a set time domain, receiving other reference signals between the PDCCH and the PDSCH, otherwise, not receiving other reference signals.
In an embodiment of the present disclosure, when the network device determines to transmit the reference signal at both the first location and the second location, the first location is located in a first time domain; determining to place the first location in a second time domain only when the first location carries the reference signal; the first time domain and the second time domain are not coincident. Here, whether the UE transmits the reference signal at the second location may be informed by a bearer time domain of the first location. For example, when the reference signal of the first position is located on the first effective OFDM symbol before the SSB, the second position is instructed to transmit the reference signal, and when the reference signal of the first position is located on other OFDM symbols, the second position is instructed not to transmit the reference signal.
