Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
First, there is an explanation as follows:
the functions performed by the power saving signal may include one or more of the following:
indicating whether the terminal needs to detect a control channel during a next Discontinuous Reception (DRX) duration (on duration);
indicating whether the terminal detects the control channel in a next period of time or is in a sleep state in the next period of time;
indicating a maximum number of multiple-input multiple-output (MIMO) streams used by the terminal;
a minimum slot offset value indicating uplink and downlink data scheduling of the terminal for a next period of time, i.e., K0, K2; may also include a minimum value of the Physical Downlink Shared Channel (PDSCH) to hybrid automatic repeat request (HARQ) ACK slot offset value K1;
indicating activation or deactivation of a secondary cell (Scell) of carrier aggregation, or indicating triggering and reporting of aperiodic Channel State Information (CSI) measurement;
Indicating a handover of a bandwidth part (BWP).
The power saving signal may be transmitted based on a structure of a control channel, and particularly, the power saving signal may be transmitted based on a structure of a PDCCH. By detecting the energy-saving signal of the PDCCH structure to implement the above-mentioned function indication, a corresponding search space needs to be configured for the PDCCH carrying the energy-saving signal.
Based on this, in various embodiments of the present invention, by transmitting the indication information, the terminal is instructed to detect the search space of the control channel carrying the energy saving information.
By adopting the scheme of the embodiment of the invention, the configuration of the energy-saving control channel searching space can be realized by sending the indication information.
The embodiment of the invention provides an information transmission method, which is applied to network equipment (such as a base station and the like), and comprises the following steps:
sending indication information; and the indication information is used for the terminal to determine the search space of the control channel carrying the energy-saving information.
The control channel carrying the energy saving information may also be referred to as an energy saving control channel.
Here, in practical applications, the following two types of configurations of the search space in NR are provided:
first, for the transmission of cell broadcast control information, the Common Search Space (CSS) for these information associates the type of control information with the search space through cell specific signaling PDCCH-ConfigCommon sent in a system message block (SIB). Part of this information is as follows:
PDCCH-ConfigCommon information element
Figure BDA0002047976140000071
The Residual Minimum System Information (RMSI), SIB1, other system messages (otherSI), paging (paging) and Random Access Response (RAR) associated search space IDs are designated by means of broadcast signaling, and search spaces corresponding to the information are respectively called Type0-PDCCH CSS, Type0A-PDCCH CSS, Type2-PDCCH CSS and Type1-PDCCH CSS. In addition, before the SIB issues the association, the broadcast control information is transmitted in the common search space of type0, i.e. the search space for transmitting RMSI, by default.
Secondly, for other common control information such as an interrupt transmission indication, a slot format indication, a search space Type3-PDCCH CSS where a power control command indication, etc. are located, and a user-specific search space (USS) for transmitting UE-specific control information are configured through PDCCH-Config of RRC signaling, which is as follows:
PDCCH-Config information element
Figure BDA0002047976140000081
and indicating the ID of the search space required to be detected to the terminal through the configuration signaling. The terminal can determine the time-frequency resource position, the detected DCI format, the aggregation level and the like of the PDCCH according to the corresponding search space configuration.
When designing an energy-saving signal based on the PDCCH structure, it is necessary to configure a period of a search space corresponding to the energy-saving signal, detect a position, and the like. Since the first method is suitable for the search space configuration of some broadcast control channels, the configuration of the search space of the energy saving signal is more reasonable through the second method, i.e. the RRC signaling configuration.
Based on this, in an embodiment, when the indication information is sent, the method may include:
and carrying the indication information through RRC configuration information.
Here, in actual use, as described above, the control information is generally configured by PDCCH-Config IE of RRC signaling. The indication information may also be configured via PDCCH-ConfigCommon IE of RRC signaling.
Based on this, in an embodiment, when the indication information is carried by RRC configuration information, the indication information may be set in a control channel configuration IE in RRC signaling. The indication information may indicate an identifier of a search space of the control channel carrying energy saving information, for example, the indication information is added to an IE such as PDCCH-ConfigCommon or PDCCH-Config. The indication information may also indicate the terminal to detect the control channel carrying the energy saving information, and a search space of the control channel carrying the energy saving information is configured by the network.
The manner of indicating the identifier of the search space of the control channel carrying the energy-saving information by adding the indication information to the PDCCH-Config IE is as follows:
PDCCH-Config information element
Figure BDA0002047976140000091
the manner of adding the indication information in the PDCCH-ConfigCommon IE to indicate the identifier of the search space of the control channel carrying the energy saving information is as follows:
PDCCH-ConfigCommon information element
Figure BDA0002047976140000092
Figure BDA0002047976140000101
Here, SearchSpaceId indicates a search space ID for detecting a control channel carrying power saving information.
The PDCCH-Config IE is added with the indication information, and the way for indicating the terminal to detect the control channel carrying the energy-saving information is as follows:
PDCCH-Config information element
Figure BDA0002047976140000102
Figure BDA0002047976140000111
here, setupirease { powersave } indicates that a control channel carrying energy saving information is to be detected; the search space used by the specific control channel is configured by the network, and the search space used by the control channel carrying the energy-saving information is configured through the search space IE.
For the second mode, the following two categories are further classified according to the control information:
the first type is information corresponding to the common search space of type3, and the transmission of such control information corresponds to a special DCIformat, so that it can be determined in which search spaces such control information needs to be detected through the DCI format of the configured search spaces. And if the search space with the corresponding format is not configured, the corresponding control information does not need to be detected.
The second type is information corresponding to the USS. Such control information scrambled by C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, or CS-RNTI(s) needs to be detected, and when the corresponding RNTI is configured for detection, detection is required in all USSs.
Based on this, in practical application, the control channel carrying the energy saving information may adopt the common search space of type3, and may also adopt USS.
Based on this, in an embodiment, when the indication information is carried by RRC configuration information, the method further includes:
the indication information is set in a search space configuration in RRC signaling.
Here, when the control channel carrying the energy saving information adopts a common search space of type3, the indication information may use a special DCI format x-y, and in the search space configuration, when the search space type is common (expressed as common in english), if the corresponding DCI format x-y is configured, it indicates that the terminal needs to perform detection on the control channel carrying the energy saving information at a time-frequency resource location corresponding to the search space; for example, dci-Format x-y is added after the existing dci-Format2-3 to indicate that the control channel carrying the energy saving information is detected in the common search space.
Based on this, in an embodiment, the indication information is located in an information field of which the search space type is common in the search space IE; the indication information is a DCI format of a control channel carrying energy-saving information.
The manner of setting the indication information in the search space IE is as follows:
SearchSpace
The IE SearchSpace defines how/where to search for PDCCHcandidates.Each search space is associated with one ControlResourceSet.
SearchSpace information element
Figure BDA0002047976140000121
Figure BDA0002047976140000131
Figure BDA0002047976140000141
Here, the energy-saving signal is transmitted in the common search space, which has the advantage of saving network resources, and multiple terminals can share the energy-saving signal, and in the information carried by the energy-saving signal, different terminals can share the same energy-saving indication information, and also different terminals can occupy different information fields to transmit the energy-saving indication information.
And when the control channel carrying the energy-saving information adopts the USS, configuring whether the search space detects the energy-saving signal in the search space configuration.
Based on this, in an embodiment, the indication information is located in an information field of the search space IE, where the search space type is specific to the user.
Here, specific implementations of the configuration may be classified into the following three types:
first, a field is added to the search space IE to set the indication information, and the position of the field can be collocated in the SearchSpace IE with SearchSpace id, controlResourceSetId, monitongslotperiodicityandoffset, duration, monitongsymbols within slot, nrofCandidates, that is, on the same level as these fields, as follows:
SearchSpace information element
Figure BDA0002047976140000142
Figure BDA0002047976140000151
Figure BDA0002047976140000161
it should be noted that the position of the added field may be any position juxtaposed to the above field, and the name of the field is not limited to the exemplary name (powersavingdetection).
That is, the indication information is in the same level of information domain as the search space Id; the indication information indicates whether a control channel carrying energy-saving information is detected in a corresponding search space; of course, in practical application, the existence of the indication information may also indicate that the terminal detects the control channel carrying the energy saving information, that is, the indication information is set in the corresponding position of the search space, that is, the indication information indicates that the control channel carrying the energy saving information is detected in the corresponding search space, instead of adopting a form taking a value as BOOLEAN.
Second, when the searchSpaceType field is ue-specific, a field is added to the dci-Formats to set the indication information, as follows:
Figure BDA0002047976140000162
Figure BDA0002047976140000171
among them, it should be noted that: the name of the domain is also not limited to the name of the example (powersavingdetection).
That is, the indication information searches the information field with the same level as the DCI format in the information field with the user-specific space type in the search space IE; the indication information indicates whether a control channel carrying energy-saving information is detected in a corresponding search space; of course, in practical application, the existence of the indication information may also indicate that the terminal detects the control channel carrying the energy saving information, that is, the indication information is set in the corresponding position of the search space, that is, the indication information indicates that the control channel carrying the energy saving information is detected in the corresponding search space, instead of adopting a form taking a value as BOOLEAN.
Thirdly, when the searchSpaceType is ue-specific, in addition to adding a DCI format m-n corresponding to energy saving information to the DCI-Formats, an arrangement is as follows:
Figure BDA0002047976140000172
that is to say, the indication information searches, in the search space IE, an information field whose space type is the same level as the DCI format in an information field dedicated to the user, and the indication information is the DCI format of the control channel carrying the energy saving information.
Another setting is as follows:
Figure BDA0002047976140000173
that is to say, the indication information is in an enumerated value range of a DCI format in an information domain whose search space type is exclusive to a user in a search space IE, and the indication information is the DCI format of the control channel carrying the energy saving information.
And the UE detects that the DCI format m-n exists in the search space, and detects a control channel carrying the energy-saving channel in the search space.
And the USS is adopted by adopting the indication information, so that the service characteristics of the user can be better adapted. This is because: at present, the related art supports that each BWP configures 10 search spaces, that is, there may be multiple user-specific search spaces, in this case, the terminal cannot distinguish which user-specific search space is used for detecting the power saving signal, and the most direct way is to detect the power saving signal in all UE-specific search spaces, which may lead to frequent detection of the power saving signal. This problem can be solved well by arranging the indication information in the search space.
Correspondingly, an embodiment of the present invention provides an information transmission method, which is applied to a terminal, and as shown in fig. 1, the method includes:
step 101: receiving indication information;
specifically, receiving RRC configuration information; the RRC configuration information carries the indication information.
