Description

Method and device for processing reference signal
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for processing a reference signal.
Background
Unlike the fourth Generation mobile communication system (4G) Long Term Evolution (LTE) that uses Cell Reference Signals (CRS), the Fifth Generation mobile communication system (5G) introduces Tracking Reference Signals (TRS) into the New air interface (New Radio, NR) for estimation of large-scale channel characteristics such as fine time/frequency synchronization, delay spread, and doppler spread. Currently, the TRS can only be configured through Radio Resource Control (RRC) signaling dedicated to the terminal, that is, can only be configured for the RRC connected terminal.
The current TRS can only be configured for an RRC connected terminal, terminals in an RRC idle state and an inactive state cannot use the TRS, and only a synchronization signal block (SS/PBCH block, SSB) can be used for synchronization tracking, and the like. However, SSBs are transmitted periodically, with a default period of 20 ms. Each time a terminal in an RRC idle state and an inactive state receives a paging signal, the terminal needs to wake up a long time in advance and receive an SSB for synchronous tracking. In LTE, since each timeslot has CRS, the terminal only needs to advance by 1 or several timeslots to detect CRS and acquire synchronization. In the 5G NR, since the terminals in the RRC idle state and the inactive state can only synchronize through the SSB, a long time is required to wake up in advance, which results in a longer procedure time for detecting the paging signal and increased energy consumption compared to the 4G LTE.

illustratively, the network side carries first information through an RRC configuration message or an RRC connection release message, where the first information is used to indicate a first reference signal that the terminal may support in an idle state or an inactive state.
Wherein, the configuration information of the first reference signal may include one or more of the following combinations: period of reference signal, frequency domain density, bandwidth, length, number of symbols and symbol interval within one slot, antenna port, reference signal usage, etc.
It is understood that (1) and (2) above configure the first reference signal directly.

(4) The terminal obtains all configuration information or partial configuration information of the multiple reference signals configured in the connection state through the RRC connection release message, wherein the configuration information is still effective in the idle state or the non-activated state.
Or, the terminal obtains, through the RRC connection release message, all or part of configuration information of the plurality of reference signals that need to be stored after entering the RRC idle state or the inactive state, or do not release or discard or suspend the terminal in the connected state.
It is understood that the above (3) and (4) are configuration information indicating which reference signals of the terminal can continue to be valid, and the valid configuration information of one or more reference signals is the configuration information of the first reference signal.
Illustratively, the network side configures one or more reference signals, e.g. reference signals #1, #2, #3, through an RRC configuration message.
The network side carries first information through an RRC connection release message, where the first information indicates that all or part of configuration information of one or more reference signals configured by the RRC of the terminal is still valid in an idle state or an inactive state, and the configuration information may include, for example, the following:
1) all configuration information of one reference signal is valid, for example, the first information indicates all configuration information of reference signal # 1.
That is, the terminal supports the reference signal # 1.
2) All configuration information of the plurality of reference signals is valid, for example, the first information indicates all configuration information of the reference signals #1, #2, # 3.
That is, the terminal supports reference signals #1, #2, # 3.

That is, the terminal supports reference signals #1, #2, # 3.
The network side indicates the terminal that all or part of configuration information of one or more reference signals configured by the RRC is still valid in an idle state or an inactive state, or may notify the terminal whether to save or release or discard or suspend part or all of configuration information of one or more reference signals configured in a connected state.
That is, the terminal may determine or assume that part or all of configuration information of one or more (corresponding to part or all) reference signals configured in the connected state continues to be valid or available in the idle/inactive state based on the first information, where the first information may be configured on the network side or agreed on by a protocol.
In some embodiments, the terminal supports the first reference signal indicated by the first information before a specified time expires or before a failure condition takes effect.
Optionally, the method further comprises: the terminal does not support the first reference signal after expiration of a specified time or after an expiration condition has been effected.
In an embodiment of the present application, the expiration of the specified time includes any one of:
(1) the timer is overtime, and the timer starts to time when the terminal enters an idle state or an inactive state or starts to support the reference signal, or the timer starts to time from the related time of sending an RRC connection release message;
(2) and the effective time expires, wherein the effective time is counted when the terminal enters an idle state or an inactive state or starts to support the reference signal, or the effective time is counted from the related time of sending the RRC connection release message.
In an embodiment of the present application, the failure condition includes any one of:
(1) the terminal receives the paging message;
(2) the terminal enters the RRC connected state.
In this embodiment of the application, the time length of the specified time or the condition that the specified time expires may be notified by the network side through RRC dedicated signaling (e.g., an RRC connection release message), configured by higher layer signaling, or agreed by a protocol, that is, the network may notify through RRC dedicated signaling, configured by higher layer signaling, or agreed by a protocol, as to an expiration condition of the first information, such as an effective time or a time length of a timer, or may notify through RRC dedicated signaling, configured by higher layer signaling, or agreed by a protocol, as to an expiration condition of the first information, such as that the first information expires after the terminal receives a paging message or enters a connected state.
For example, the terminal may support the first reference signal within a predefined timer or validation time length configured on the network side, but the terminal may not continue to support the first reference signal when the timer expires or the validation time expires. For another example, the terminal may always support the first reference signal until the terminal receives a paging message or enters an RRC connected state.
Alternatively, if the first information is the configuration information of the first reference signal obtained through the RRC configuration message, the time length of the specified time or the condition that the specified time expires or the failure condition may be preset or given in the RRC configuration message.
Alternatively, if the first information is the configuration information of the first reference signal obtained through the RRC configuration message, the time length of the specified time or the condition that the specified time expires or the failure condition may be preset or given in the RRC connection release message.
Alternatively, if the first information is configuration information of the first reference signal obtained through an RRC connection release message, the time length of the specified time or a condition that the specified time expires or a failure condition may be preset or given in the RRC connection release message.
Alternatively, if the first information is configuration information of the first reference signal obtained through an RRC connection release message, the time length of the specified time or a condition that the specified time expires or a failure condition may be preset or given in the RRC configuration message.
Optionally, if the first information is information that all or part of configuration information of a reference signal configured in a connected state obtained through an RRC connection release message is still valid in an idle state or an inactive state; or when all or part of the configuration information of the multiple reference signals is still valid in the idle state or the inactive state, the time length of the specified time or the condition or the failure condition of the specified time expiring may be preset, or given in the RRC connection release message, or given in the RRC configuration message.
Optionally, if the first information is obtained through an RRC configuration message and there is no additional configuration message about the first information or there is no configuration information for a related specified time length or there is no additional configuration information for a failure condition, the expiration of the failure condition or the specified time includes: the terminal receives the paging message or the terminal enters a connected state or has no time limit. That is, in this case, the failure condition or the specified time may be preset.
Optionally, if the first information is obtained through an RRC connection release message and there is no additional configuration message about the first information or no configuration information for a related specified time length or no additional configuration information for a failure condition, the expiration of the failure condition or the specified time includes: the terminal receives the paging message or the terminal enters a connected state or has no time limit. That is, in this case, the failure condition or the specified time may be preset.
Optionally, the terminal enters an RRC idle state or an inactive state, the terminal starts a timer or an effective time to start timing, and the terminal cannot receive the first reference signal after the timer expires or the effective time expires.
Optionally, if the network side configures the configuration information of the first reference signal supported by the terminal only through the RRC configuration message and there is no other configuration message related to the first information, for example, there is no RRC connection release message to further indicate that all or part of the configuration information of one or more reference signals configured by the RRC by the terminal is still valid in the idle state or the inactive state, the terminal may always support the first reference signal, or no longer support the first reference signal after receiving the paging message, or no longer support the first reference signal after entering the RRC connected state.
In some embodiments, in step 201, the terminal supports the first reference signal indicated by the first information in an initial bandwidth part (BWP).
It is understood that the above-mentioned initial BWP may also be referred to as a default BWP.
For example, the network side indicates, through the first information, that the bandwidth of the first reference signal supported by the terminal in the idle state or the inactive state is within the bandwidth range of the initial BWP, and the terminal supports the first reference signal indicated by the first information according to the configured bandwidth range of the first reference signal in the initial BWP.
For another example, the network side indicates, through the first information, that the bandwidth of the first reference signal supported by the terminal in the idle state or the inactive state exceeds the bandwidth range of the initial BWP, and the terminal supports the first reference signal indicated by the first information only in a portion of the initial BWP where the bandwidth of the first reference signal configured according to the first information overlaps with the initial BWP. For example, if the frequency domain resource of the first reference signal exceeds the initial BWP of the terminal, the terminal can only receive the first reference signal in the initial BWP.
For another example, the network side notifies only part of configuration information of one or more reference signals configured by the RRC that is valid, where configuration information of bandwidth or frequency domain location is not included, and the terminal may assume that the first reference signal indicated by the first information is supported in the initial BWP or that the terminal supports the first reference signal indicated by the first information within a bandwidth range of the first reference signal agreed by the protocol.
Optionally, the terminal may further include, according to one or a combination of the following configuration information of the first reference signal in the first information: frequency domain density, length, number of symbols within a slot, symbol interval, supporting the first reference signal in the initial BWP or within the bandwidth of the first reference signal as agreed by the protocol.
For another example, the network side does not include configuration information of the bandwidth or frequency domain position of the first reference signal in the first information, and the terminal may assume that the first reference signal indicated by the first information is supported in the initial BWP, or that the terminal supports the first reference signal indicated by the first information within the bandwidth range of the first reference signal agreed by the protocol.
Optionally, the terminal may further include, according to one or a combination of the following configuration information of the first reference signal in the first information: frequency domain density, length, number of symbols within a slot, symbol interval, supporting the first reference signal in the initial BWP or within the bandwidth of the first reference signal as agreed by the protocol.
In some embodiments, in step 201, the terminal receives second configuration information from the network side; and supporting the first reference signal indicated by the first information in an idle state or an inactive state according to the second configuration information.
Optionally, the second configuration information may be a higher layer signaling or a radio resource control connection release message.
Taking the second configuration information as an example of a higher layer signaling, the network side over-higher layer signaling configures the specific function of the terminal to be started, and the specific function includes: the terminal supports the first reference signal indicated by the first information in an idle state or an inactive state. For example, the network side over-high layer signaling configures the terminal that the function is turned off, that is, although the terminal has received the first information, the terminal may not support the first reference signal indicated by the first information in the idle state or the inactive state.
Taking the second configuration information as an example of the rrc connection release message, the network side notifies the terminal of the specific function being turned on through the rrc connection release message, where the specific function includes: the terminal supports the first reference signal indicated by the first information in an idle state or an inactive state.
For another example, the network side notifies the terminal of the function shutdown through the rrc connection release message, that is, although the terminal has received the first information, the terminal may not support the first reference signal indicated by the first information in the idle state or the inactive state.
In some embodiments, in step 201, according to the protocol convention, the terminal supports the first reference signal indicated by the first information in an idle state or an inactive state.
For example, the protocol is agreed, and after receiving the first information, the terminal may support the first reference signal in an idle state or an inactive state according to the indication of the first information.
That is, the first reference signal indicated by the first information may be supported after the terminal enters the RRC idle state or the inactive state by agreement.
In this embodiment of the application, the network side device notifies the terminal of configuration information of reference information that can be used in an RRC idle state or an inactive state or configuration information of reference signals that continue to be supported in an RRC connected state, and the terminal may receive or support the reference signals in the RRC idle state or the inactive state, so that the terminal may be assisted to reduce energy consumption by using the reference signals. The indication mode of the reference signal can be effectively applied to a network, a network side device can predict that a certain terminal is always within a specific service range of the network side device within a certain time period through early statistics, but can frequently switch between an RRC idle state/inactive state and a connected state, for example, an indoor terminal in an office or a home has a limited moving range and is not always in the RRC idle state/inactive state, so that the network side device can reserve the reference signal configuration in the RRC connected state for the terminal, and when the terminal enters the RRC idle state/inactive state, the terminal can still use the reference signal to assist the terminal to perform time-frequency domain synchronization, thereby reducing energy consumption.
Further, reference signal configuration can be performed through a separate signaling of each terminal, so that the problem that the first reference signal is configured for the idle state terminal or the inactive state terminal by using a broadcast message is solved. Specifically, if the network side broadcasts configuration information of a currently existing TRS of a connected terminal for an idle terminal and an inactive terminal through a system message, but if the configuration information of the TRS of the connected terminal changes, or the connected terminal leaves the cell or enters an inactive terminal, the network side can only update change information or stop information notifying the configuration of the TRS of the idle terminal and the inactive terminal through the system message. Because it cannot be guaranteed that the configuration information of the connected terminal TRS is unchanged for a long time or the connected terminal is always in the connected state of the cell, the base station may frequently change the system message to update the broadcasted configuration information of the TRS, which causes the idle or inactive terminal to frequently receive a new system message in order to receive the configuration information of the TRS, thereby increasing power consumption. According to the embodiment of the application, on one hand, the system message is prevented from occupying air interface resources frequently, and on the other hand, the frequent system message receiving behavior of the terminal is avoided (the idle-state terminal and the connected-state terminal can perform a system message updating process).
In addition, the network side device can autonomously determine the time for reserving the configuration information of the reference signal for different RRC idle state/inactive state terminals, and the network side device does not need to always reserve the reference signal for all the idle state/inactive state terminals, thereby avoiding occupation of air interface resources.
