Description

Terminal capability processing method and device, network side equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing terminal capability, a network side device, and a terminal.

Background

In 5G NR (5G New Radio, 5G New air interface), a terminal needs to report a related capability of search space monitoring (e.g., PDCCH blind detection). The capability represents the span (time period) composition supported by the terminal, including the time domain length of the span and the time interval between two adjacent spans. The terminal reports a group of capabilities, which can include a combination of multiple spans, and is represented by (X, Y), where X is the number of symbols spaced between two adjacent spans, and Y is the number of consecutive symbols included in one span. After the terminal reports the capability, the position of the search space of the downlink control channel configured on the network side and the interval between the search space and the downlink control channel need to meet the limitation of (X, Y). The reporting capability does not limit the number of blind tests or the number of non-overlapping CCEs (Control Channel Elements) in each span. The number of blind tests or the number of non-overlapping CCEs is defined for each slot only. This means that the network side can configure a large number of BDs (Blind Detection) or non-overlapping CCEs in one span, and configure very few BDs and CCEs in other spans. This is a great challenge for the terminal. On the other hand, URLLC (ultra-reliable, low-delay communication) service requires low-delay and highly reliable downlink control transmission, resulting in the number of overlapping CCEs to be processed in a time slot being much larger than the currently defined terminal capability.

For a terminal with URLLC capability, in order to make the capability of the terminal more uniformly distributed in each span and thereby reduce processing delay, the monitoring capability in each span needs to be further limited, for example, the number of blind tests to be executed in the span or the number of non-overlapping CCEs, such as (X, Y, M), is reported while (X, Y) is reported; m is the number of non-overlapping CCEs (Control Channel Elements) supported by the terminal in each span, or the number of BDs.

If the network side performs configuration according to (X, Y, M) and the number of the configured spans is small, the number of PDCCHs or non-overlapping CCEs that can be monitored in one time slot is too small, thereby wasting the terminal capability. When the terminal reports the monitoring capability about the timeslot and the monitoring capability about the span at the same time, there is no clear scheme for how the network side performs the search space configuration at present.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an embodiment of the present invention provides a method for processing terminal capabilities, which is applied to a network device, and includes:

and step 11, receiving at least one set of first downlink control channel monitoring capability information which is reported by the terminal and does not contain the maximum blind detection capability indication of the terminal in the span of the time period and at least one set of second downlink control channel monitoring capability information which contains the maximum blind detection capability indication of the terminal in the span. Wherein a slot contains at least one span.

For example, the first downlink control channel listening capability information is (X, Y), where X is the number of symbols spaced between two adjacent spans, and Y is the number of consecutive symbols included in one span; the second downlink control channel monitoring capability information is (X, Y, M), where X is the number of symbols spaced between two adjacent spans, and Y is the number of consecutive symbols included in one span; m is the maximum blind detection capability indication of the terminal in each span.

Step 12, determining target downlink control channel monitoring capability information for performing downlink control channel search space configuration according to a preset rule;

In this step, the network side device may use different downlink control channel monitoring capability information to configure the downlink control channel search space in different scenarios according to the preset rule, so as to avoid that the terminal cannot exert the maximum capability of the terminal in some configuration scenarios.

As an alternative embodiment, the indication of the maximum blind detection capability of the terminal in the span includes:

and/or the presence of a gas in the gas,

maximum number of blind detections supported by the terminal within the span.

For example, the second downlink control channel listening capability information is (X, Y, M), where M is the maximum number of non-overlapping CCEs supported by each intra-span terminal, or M is the maximum number of blind detections supported by each intra-span terminal.

The embodiment of the present invention provides at least three ways of determining the monitoring capability information of the target downlink spatial channel, and three different ways are described below:

the first method is as follows: namely, step 12 includes:

It should be noted that the network side device may determine or estimate the total number of blind detections actually required to be configured in one time slot according to the information of the current state of the terminal, the service to be transmitted, and the like, or the total number of non-overlapping CCEs actually required to be configured in one time slot.

Optionally, the determining, according to a sum of blind detection times actually required to be configured by all the span internal network side devices of a time slot or a sum of number of non-overlapping CCEs actually required to be configured by all the span internal network side devices of a time slot, the target downlink control channel monitoring capability information includes:

if the sum of the times or the sum of the quantities is smaller than or equal to a first threshold value, determining that the target downlink control channel monitoring capability information is the first downlink control channel monitoring capability information; that is, the network side device needs to comply with the first downlink control channel monitoring capability information when configuring the downlink control channel search space;

if the sum of the number is larger than a first threshold value, determining that the target downlink control channel monitoring capability information is the second downlink control channel monitoring capability information; that is, the network side device needs to comply with the second downlink control channel monitoring capability information when configuring the downlink control channel search space;

It should be noted that, when configuring a downlink control channel search space for the terminal under the condition that the target downlink control channel monitoring capability information is the first downlink control channel monitoring capability information, the number of blind tests or the number of non-overlapping CCEs in each span is not limited by M.

Or, in the case that the target downlink control channel monitoring capability information is the second downlink control channel monitoring capability information, the method further includes:

Example 1

Assuming that the terminal supports both the eMBB (enhanced mobile bandwidth) and the URLLC services, the terminal needs to report the first downlink control channel monitoring capability information (X, Y) and the second downlink control channel monitoring capability information (X, Y, M) at the same time. Wherein X is the number of spaced symbols between two adjacent spans, and Y is the number of continuous symbols contained in one span; m is the maximum number of non-overlapping CCEs supported by each intra-span terminal, or the maximum number of blind detections supported by each intra-span terminal. The first downlink control channel listening capability information (X, Y) only specifies the span-to-span interval and the span time domain length, and does not limit the number of blind detections in each span or the number of non-overlapping CCEs.

The terminal reports three sets of first downlink control channel monitoring capability information, namely (2, 2), (4, 3), (7, 3); and three sets of second row control channel listening capability information, respectively (2, 2, 16), (4, 3, 24), (7, 3, 32);

network side equipment receives first downlink control channel monitoring capability information and second downlink control channel monitoring capability information reported by a terminal;

the network side equipment calculates the total number S of non-overlapping CCEs which are actually required to be configured in a time slot and/or the total number S of blind detection according to actual requirements;

comparing the total number S with a threshold T1, where T1 is a first threshold predefined by the protocol (different T1 values may be defined for different subcarrier intervals), or a maximum number of blind detected or non-overlapping CCEs within each time slot defined in the protocol;

determining target downlink control channel listening capability information that should be followed when actually configuring a downlink control channel search space, assuming that T1 is 56 for a 15kHz subcarrier spacing, representing the number of non-overlapping CCEs:

if S < ═ T1, assuming that S is 48, configuring a downlink control channel search space according to the first downlink control channel monitoring capability information reported by the terminal, that is, not needing to be limited by the maximum blind detection capability in each span specified by the second downlink control channel monitoring capability information;

if S > T1, assuming that S is 96, configuring a downlink control channel search space (X, Y, M) according to second downlink control channel monitoring capability information reported by the terminal, that is, the network side needs to ensure that an interval between two actually configured continuous spans is not less than X symbols, a time domain duration of each span is not greater than Y symbols, and the number of blind detection or non-overlapping CCEs in each span is not greater than M.

The second method comprises the following steps: namely, step 12 includes:

It should be noted that the network side device may determine or predict the number of spans actually required to be configured in one timeslot according to the current state of the terminal, the service to be transmitted, and other information.

Optionally, the determining, according to the number of spans actually required to be configured in a time slot, the target downlink control channel monitoring capability information includes:

if the number of the spans which are actually required to be configured in one time slot is smaller than or equal to a second threshold value, determining that the target downlink control channel monitoring capability information is the first downlink control channel monitoring capability information; that is, the network side device needs to comply with the first downlink control channel monitoring capability information when configuring the downlink control channel search space;

if the number of the spans which are actually required to be configured in one time slot is larger than a second threshold value, determining the target downlink control channel monitoring capability information as the second downlink control channel monitoring capability information; that is, the network side device needs to comply with the second downlink control channel monitoring capability information when configuring the downlink control channel search space;

Example two

The terminal reports first downlink control channel monitoring capability information (2, 2) and second downlink control channel monitoring capability information (2, 2, 16), which means that the terminal supports 14/2-7 spans in at most one timeslot, and it is assumed that the span number threshold value T2-7;

the network side equipment calculates the number A of the span required to be configured in a time slot according to the actual requirement;

comparing the number a with a threshold value T2, where T2 is a value predefined by a protocol (different T2 values may be defined for different subcarrier intervals), or is the maximum span number in one timeslot supported in the terminal reporting capability;

determining target downlink control channel monitoring capability information that should be followed when a downlink control channel search space is actually configured, assuming that T2 is 7 for a 15kHz subcarrier spacing;

if A < T1, and if A < 3, configuring a downlink control channel search space according to the first downlink control channel monitoring capability information reported by the terminal, that is, not limited by the maximum blind detection capability in each span specified by the second downlink control channel monitoring capability information;

otherwise, assuming that a is 7, configuring a downlink control channel search space (X, Y, M) according to the second downlink control channel monitoring capability information reported by the terminal, that is, the network side needs to ensure that the interval between two actually configured continuous spans is not less than X symbols, the time domain duration of each span is not greater than Y symbols, and the number of blind detection or non-overlapping CCEs in each span is not greater than M.

The third method comprises the following steps: namely, step 13 includes:

It should be noted that the network side device may determine or estimate the number of interval symbols between two adjacent spans that actually need to be configured according to the information of the current state of the terminal, the service to be transmitted, and the like.

Optionally, the determining, according to the number of interval symbols between two adjacent spans that actually need to be configured in a time slot, the target downlink control channel monitoring capability information includes:

if the number of the spaced symbols between any two adjacent spans actually required to be configured in a time slot is greater than the number of the spaced symbols between two adjacent spans indicated in the second downlink control channel monitoring capability information reported by the terminal, determining that the target downlink control channel monitoring capability information is the first downlink control channel monitoring capability information; that is, the network side device needs to comply with the first downlink control channel monitoring capability information when configuring the downlink control channel search space;

otherwise, determining the target downlink control channel monitoring capability information as the second downlink control channel monitoring capability information; that is, the network side device needs to comply with the second downlink control channel monitoring capability information when configuring the downlink control channel search space.

Example three

The terminal reports the first downlink control channel monitoring capability information (2, 2) and the second downlink control channel monitoring capability information (2, 2, 16) and (4, 3, 24);

the network side equipment determines the span position needing actual configuration and the actual number G of interval symbols between adjacent spans according to actual requirements;

comparing G with the maximum interval X in the second row of control channel listening capability information, i.e. with 4:

and if the number of interval symbols between any two adjacent spans is more than 4, following the first downlink control channel monitoring capability information during configuration. For example, the MO of the actually configured search space satisfies two spans, and the two spans are spaced by 7 symbols. Then, when configuring the downlink control channel search space, the time domain continuous symbol of each span is at most 2 symbols, and the number of blind detection and non-overlapping CCEs in each span is not limited by M, only the limitation of each time slot needs to be satisfied;

otherwise, the second downlink control channel monitoring capability information, i.e., (X, Y, M), needs to be followed during configuration.

It should be noted that, in the embodiment of the present invention, specific values of X, Y, and M are not limited, and the above is only a specific example to better describe the method provided in the embodiment of the present invention.

In summary, in the embodiment of the present invention, when the terminal reports the first downlink control channel monitoring capability information and the second downlink control channel monitoring capability information at the same time, the network side device determines to perform downlink control channel search space configuration according to the target downlink control channel monitoring capability information according to the preset rule, so as to avoid that the maximum capability of the terminal cannot be exerted in some configuration scenarios.

As shown in fig. 2, an embodiment of the present invention further provides a method for processing terminal capabilities, which is applied to a terminal, and includes:

step 21, reporting at least one set of first downlink control channel monitoring capability information not containing the maximum blind detection capability indication of the terminal in the span of the time period and at least one set of second downlink control channel monitoring capability information containing the maximum blind detection capability indication of the terminal in the span to the network side equipment.

For example, the first downlink control channel listening capability information is (X, Y), where X is the number of symbols spaced between two adjacent spans, and Y is the number of consecutive symbols included in one span; the second downlink control channel monitoring capability information is (X, Y, M), where X is the number of symbols spaced between two adjacent spans, and Y is the number of consecutive symbols included in one span; m is the maximum blind detection capability indication of the terminal in each span. The first downlink control channel listening capability information (X, Y) only specifies the span-to-span interval and the span time domain length, and does not limit the number of blind detections in each span or the number of non-overlapping CCEs.

and/or the presence of a gas in the gas,

maximum number of blind detections supported by the terminal within the span.

Bearing the above example, the embodiment of the present invention further includes:

and receiving a downlink control channel searching space configured by a network side, wherein one span comprises at least one downlink control channel searching space.

As yet another alternative embodiment, the method further comprises:

In short, the terminal determines, according to the downlink control channel search space configured by the network-side device, that the number of blind tests in at least one span (referred to as a target span) configured by the network-side device or the number of non-overlapping CCEs is greater than the maximum blind test capability of the terminal in the span, and then the terminal performs a downlink control channel dropping (dropping) operation in the target span.

Optionally, the target span configured by the network side device includes at least one downlink control channel search space;

as an optional embodiment, the performing the downlink control channel dropping operation within the target span includes:

For example, the terminal reports three sets of first downlink control channel monitoring capability information, which are (2, 2), (4, 3), (7, 3); and three sets of second row control channel listening capability information, respectively (2, 2, 16), (4, 3, 24), (7, 3, 32);

for the actually configured downlink control channel search space, the number of blind detection times or non-overlapping CCEs in any span which meets (2, 2, 16) does not exceed 16, the number of blind detection times or non-overlapping CCEs which meets (4, 3, 24) does not exceed 24, the number of blind detection times or non-overlapping CCEs which meets (7, 3, 32) does not exceed 32, and the terminal executes PDCCH (physical Downlink control channel) discarding operation in the corresponding span according to the limitation of each M; otherwise, according to the maximum blind detection capability of the terminal in a time slot specified by the protocol, the PDCCH discarding operation is executed by taking the time slot as a unit.

For another example, the terminal reports the first downlink control channel monitoring capability information (2, 2) and the second downlink control channel monitoring capability information (2, 2, 16);

for the actually configured search space, the number of blind detection times in any span conforming to (2, 2, 16) or the number of non-overlapping CCEs does not exceed 16, and the terminal executes PDCCH discarding operation in the corresponding span according to the limitation of M; otherwise, according to the maximum blind detection capability of the terminal in a time slot specified by the protocol, the PDCCH discarding operation is executed by taking the time slot as a unit.

For another example, the terminal reports the first downlink control channel monitoring capability information (2, 2), and the second downlink control channel monitoring capability information (2, 2, 16) and (4, 3, 24);

for the actually configured search space, the number of blind detection times in any span conforming to (2, 2, 16) or the number of non-overlapping CCEs does not exceed 16, and the number of blind detection times in any span conforming to (4, 3, 24) or the number of non-overlapping CCEs does not exceed 24, and the terminal executes PDCCH (physical Downlink control channel) discarding operation in the corresponding span according to the limitation of each M; otherwise, according to the maximum blind detection capability of the terminal in a time slot specified by the protocol, the PDCCH discarding operation is executed by taking the time slot as a unit.

As another optional embodiment, the performing the downlink control channel dropping operation within the target span includes:

For example, the terminal reports the first downlink control channel monitoring capability information (2, 2) and the second downlink control channel monitoring capability information (2, 2, 16); meaning that the terminal supports 14/2-7 spans in at most one timeslot.

For the actually configured search space, if the number of the actual spans configured in one time slot is less than 7, the terminal executes PDCCH discarding operation in the corresponding span according to the limitation of M; otherwise, according to the maximum blind detection capability of the terminal in a time slot specified by the protocol, the PDCCH discarding operation is executed by taking the time slot as a unit.

For example, the terminal reports the first downlink control channel listening capability information (2, 2), and the second downlink control channel listening capability information (2, 2, 16) and (4, 3, 24);

for the actually configured search space, if the number of the symbols at the interval between any two adjacent spans actually configured in a time slot is more than 4, the PDCCH discarding operation is executed by taking the time slot as a unit according to the maximum blind detection capability of the terminal in the time slot specified by the protocol; otherwise, the terminal executes the PDCCH discarding operation in the corresponding span according to the limitation of M.
