CAPABILITY INDICATION METHOD AND APPARATUS, CAPABILITY DETERMINATION METHOD AND APPARATUS, COMMUNICATION DEVICE, AND STORAGE MEDIUM

TECHNICAL FIELD

The present disclosure relates to the field of communication technologies, and in particular to a capability indication method and apparatus, a capability determination method and apparatus, a communication device, and a computer-readable storage medium.

BACKGROUND

In non-terrestrial networks (NTN), a terminal can communicate with a base station via a satellite. A timing advance (TA) to be compensated for is larger because the satellite is moving through the air and is farther away from the terminal. At present, the terminal can determine a part of the timing advance that needs to be compensated by the terminal (the network side can compensate the other part of the timing advance), and the terminal can pre-compensate the timing advance by means of uplink transmission timing advance pre-compensation.

In addition, to provide communication efficiency, the terminal, when performing uplink transmission, such as transmitting a physical uplink share channel (PUSCH), may transmit a long PUSCH, which can be understood as the time domain resource occupied by the transmitting the PUSCH is relatively long.

In this case, the information to be transmitted can be transmitted in segments. For example, when transmitting the long PUSCH, the information to be transmitted can be divided into a plurality of segments, and the uplink transmission can be carried out separately for each of the plurality of segments.

Considering the timing advance compensation, for each of the plurality of segments, it is necessary to pre-compensate the uplink transmission timing advance when the uplink transmission is carried out, which can be called uplink transmission timing advance pre-compensation for segment-based transmission.

Since the uplink transmission timing advance pre-compensation for segment-based transmission needs to pre-compensate the timing advance for each of the plurality of segments separately, the operation is relatively complicated, so not all terminals support the uplink transmission timing advance pre-compensation for segment-based transmission.

FIG. 1 is a flowchart illustrating a capability indication method according to an embodiment of the present disclosure. The capability indication method shown in this embodiment may be performed by a terminal. The terminal includes, but is not limited to, a communication device such as a cell phone, a tablet, a wearable device, a sensor, an internet of things (IoT) device, and the like. The terminal may communicate with a network-side device, the network-side device includes, but is not limited to a network-side device (such as a base station, a core network, and the like) in a communication system such as a 4th generation (4G) communication system, a 5G communication system, a 6G communication system, etc.

As shown in FIG. 1, the method may include step S101.

At step S101, capability indication information is transmitted to a network-side device, where the capability indication information is configured to indicate a capability of the terminal to support uplink transmission timing advance pre-compensation for segment-based transmission.

In an embodiment, the terminal may determine its own capability to support the uplink transmission timing advance pre-compensation for segment-based transmission, and the capability includes supporting the uplink transmission timing advance pre-compensation for segment-based transmission, and not supporting the uplink transmission timing advance pre-compensation for segment-based transmission. Further, the capability indication information is transmitted to the network-side device, and the network-side device may determine, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission. For example, the network-side device can determine that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission, or determine that the terminal does not support the uplink transmission timing advance pre-compensation for segment-based transmission.

For example, the capability can be indicated by one bit, where “1” means that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission, and “0” means that the terminal does not support the uplink transmission timing advance pre-compensation for segment-based transmission.

According to the present disclosure, that the network-side device determines the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission can be ensure, such that the terminal can be appropriately configured based on the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission, therefore good communication quality is ensured.

FIG. 2 is a flowchart illustrating a capability indication method according to another embodiment of the present disclosure. As shown in FIG. 2, the method further includes step S201.

At step S201, when a plurality of segments of uplink transmission overlap, overlapping portions of the plurality of segments are punctured or dropped.

In an embodiment, in a scenario where a terminal performs uplink transmission based on segments, the terminal may divide the uplink transmission (e.g., PUSCH, physical random access channel (PRACH), etc.) into a plurality of segments. When the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission, the uplink transmission timing advance pre-compensation may be performed separately for each segment, which may result in overlap between the compensated segments. In this case, the terminal needs to puncture or drop the overlapping portions of the segments, i.e., on the time domain resource corresponding to the overlapping portions, a resource of only one segment is transmitted, and a resource of the other segment on the time domain resource is not transmitted, such that confusion in the uplink transmission is avoided.

Illustrated by the example of two segments (e.g., segment 1 and segment 2) in the plurality of segments, the overlapping and non-overlapping situations of segments are illustrated respectively.

FIG. 3 is a schematic diagram illustrating segments with overlap according to an embodiment of the present disclosure.

As shown in FIG. 3, for the network side, the segment 1 precedes the segment 2 in the time domain. When the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission, the uplink transmission timing advance pre-compensation may be performed separately for the segment 1 and the segment 2, e.g., a timing advance pre-compensated for the segment 1 is TA1, and a timing advance pre-compensated for the segment 2 is TA2.

For example, when there is no gap in the time domain between the segment 1 and the segment 2 before the pre-compensation, and TA2 is greater than TA1, there is a portion of the pre-compensated segment 2 that overlaps with the pre-compensated segment 1 in the time domain. In this case, the terminal needs to puncture or drop the portion of the pre-compensated segment 1 that overlaps with the pre-compensated segment 1, i.e., on the time domain resource corresponding to the overlapping portion, information of only the segment 1 is transmitted, and information of the segment 2 on this time domain resource is not transmitted.

It is to be noted that the terminal may also, optionally, puncture or drop a portion of the pre-compensated segment 1 that overlaps with the pre-compensated segment 2, i.e., on the time domain resource corresponding to the overlapping portion, information of only the segment 2 is transmitted, and information of the segment 1 on this time domain resource is not transmitted.

With respect to the segments with overlapping portions, the terminal can determine, independently, or based on a configuration of the network-side device, or based on a protocol agreement, the specific choice that is to puncture or drop the relatively earlier segment in the time domain (such as the segment 1), or to puncture or drop the relatively later segment in the time domain (such as the segment 2).

FIG. 4 is a schematic diagram illustrating segments without overlap according to an embodiment of the present disclosure.

It is to be noted that, in some cases, the uplink transmission timing advance pre-compensation is performed for the segment 1 and the segment 2 respectively, even if TA2 is greater than TA1, the segment 2 and the segment 1 may not overlap. For example, as shown in FIG. 4, there is a gap, e.g., a gap 1, between the segment 1 and the segment 2 in the time domain before the pre-compensation, and since the gap 1 is large enough, after the pre-compensation for the segment 1 based on TA1 and the pre-compensation for the segment 2 based on TA2, there is still a gap, e.g., a gap 2, between the segment 2 and the segment 1, such that there is no overlap between the segment 1 and the segment 2 after the pre-compensation.

In an embodiment, the capability indication information, when indicating that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission, is further configured to indicate that the terminal supports puncturing or dropping the overlapping portions of the plurality of segments based on a first time domain granularity.

In an embodiment, the terminal performs the uplink transmission on time domain resource, which include a plurality of time domain granularities from large to small, and puncturing or dropping the overlapping portions of the plurality of segments by the terminal may be puncturing or dropping the overlapping portions of the plurality of segments based on a first time domain granularity, i.e., determining a time domain resource of the first time domain granularity corresponding to the overlapping portion, and then puncturing or dropping information within the determined time domain resource of the segment where the overlapping portion to be punctured or dropped is.

However, due to different capabilities of different terminals, some terminals can puncture or drop a relatively large amount of information, i.e., the first time domain granularity is relatively large when the overlapping portions of the plurality of segments are punctured or dropped based on the first time domain granularity; some terminals can only puncture or drop relatively little information, i.e., the first time domain granularity is relatively small when the overlapping portions of the plurality of segments are punctured or dropped based on the first time domain granularity.

Thus, the terminal may indicate, by the capability indication information, that the terminal supports puncturing or dropping the overlapping portions of the plurality of segments based on the first time domain granularity, such that the network-side device can determine the first time domain granularity, and thereby determine a size of the time domain granularity on which the terminal can puncture or drop the overlapping portions of the segments, so that the network-side device can appropriately configure the terminal based on the first time domain granularity, therefore good communication quality is ensured.

In an embodiment, the first time domain granularity includes at least one of:

- a time domain symbol (e.g., orthogonal frequency division multiplexing (OFDM) symbol), a time slot, a subframe.

Illustrated by the example of the embodiment shown in FIG. 3, the portion of the pre-compensated segment 2 that overlaps with the segment 1 corresponds to six time domain symbols. When the first time domain granularity is a time domain symbol, only the overlapping portion of the segment 2 may be punctured or dropped. When the first time domain granularity is a time slot, it may determine a time slot in which the six time domain symbols are located, and thus further determine that the information of the segment 2 in this time slot shall be punctured or dropped. When the first time domain granularity is a subframe, it may determine a subframe in which the six time domain symbols are located, and thus further that the information of the segment 2 in this subframe shall be punctured or dropped.

In an embodiment, where the capability indication information is configured to indicate both the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission, and to indicate that the terminal supports puncturing or dropping the overlapping portions of the plurality of segments based on the first time domain granularity, the capability indication information may be indicated by two bits, e.g., the correspondence between the indication information and the capability is shown in Table 1 below.

FIG. 5 is a flowchart illustrating a capability indication method according to another embodiment of the present disclosure. As shown in FIG. 5, the method further includes the following steps S501 to S502.

At step S501, it is determined that the uplink transmission timing advance pre-compensation for segment-based transmission is not supported.

At step S502, receiving a scheduling instruction with a transmission duration greater than a preset duration is not expected.

In an embodiment, when the terminal determines that the uplink transmission timing advance pre-compensation for segment-based transmission is not supported, the uplink transmission carried out in general is no longer than a preset duration in the time domain, so that a transmission duration for the uplink transmission is not too large, e.g., not larger than the preset duration. Therefore, the terminal cannot expect to receive a scheduling instruction with a transmission duration greater than the preset duration.

FIG. 6 is a flowchart illustrating a capability indication method according to still another embodiment of the present disclosure. As shown in FIG. 6, the method further includes the following steps S601 to S603.

At step S601, it is determined that the segment-based transmission is configured for the terminal.

At step S602, it is determined that at least one first segment of a plurality of segments of uplink transmission has a transmission duration greater than the preset duration.

At step S603, only a portion of the at least one first segment within the preset duration is transmitted, or transmission of the at least one first segment is abandoned.

In an embodiment, when the terminal determines that the uplink transmission timing advance pre-compensation for segment-based transmission is not supported, although the network-side device can determine, based on the capability indication information, that the terminal does not support the uplink transmission timing advance pre-compensation for segment-based transmission, the network-side device generally does not transmit the scheduling instruction, with a transmission duration greater than a preset duration, to the terminal.

However, the network-side device may still configure the terminal to perform segment-based transmission. For example, perform the uplink transmission after dividing a regular PUSCH into the plurality of segments. In this case, since the terminal does not perform long PUSCH uplink transmission, the transmission duration of each uplink transmission is not greater than the preset duration.

Therefore, even if there is a first segment with a transmission duration greater than the preset duration, for the first segment, only the portion within the preset duration range of the first segment is transmitted. For example, only the portion of the first segment that continues for the preset duration from the starting time domain position is transmitted. Alternatively, for the first segment with a transmission duration greater than the preset duration, the terminal can directly abandon the transmission of the first segment. Accordingly, problems arising from uplink transmission in excess of the capability of the terminal can be avoided.

FIG. 7 is a flowchart illustrating a capability indication method according to still another embodiment of the present disclosure. As shown in FIG. 7, the method further includes the following steps S701 to S703.

At step S701, it is determined that the uplink transmission timing advance pre-compensation for segment-based transmission is supported.

At step S702, configuration information transmitted by the network-side device is received.

At step S703, a transmission duration for each of a plurality of segments of uplink transmission is determined based on the configuration information.

The configuration information includes, but is not limited to, radio resource control (RRC) signaling, media access control layer control element (MAC CE), physical layer signaling, and the like.

In an embodiment, when the terminal determines that the uplink transmission timing advance pre-compensation for segment-based transmission is supported, the uplink transmission can include the transmission of uplink information carrying the PUSCH or other uplink channels, so that the transmission duration for the uplink transmission can be relatively large, and the network-side device can also configure the segment-based transmission for the terminal.

In this case, the terminal can divide the uplink transmission into a plurality of segments, and the network-side device can transmit configuration information to the terminal, and configure a transmission duration for each segment for the terminal through the configuration information. Accordingly, the terminal can determine the transmission duration for each segment according to the transmission duration in the configuration information.

FIG. 8 is a flowchart illustrating a capability indication method according to still another embodiment of the present disclosure. As shown in FIG. 8, the method further includes the following steps S801 to S804.

At step S801, it is determined that the uplink transmission timing advance pre-compensation for segment-based transmission is supported.

At step S801, configuration information transmitted by the network-side device is received, where the configuration information includes a plurality of candidate transmission durations.

At step S803, it is determined that a correlation between ephemeris information and transmission duration for segment.

At step S804, a transmission duration, corresponding to each segment, in the plurality of candidate transmission durations is determined based on current ephemeris information and the correlation.

In this case, the terminal can divide the uplink transmission into a plurality of segments, and the network-side device can transmit the configuration information to the terminal, and configure the plurality of candidate transmission durations for the terminal through the configuration information, subsequently, the terminal can further determine the transmission duration for each segment from the plurality of candidate transmission durations.

In an embodiment, there may be a correlation between ephemeris information and transmission duration for a segment. For example, there may be a correlation between tilt angle in ephemeris information and transmission duration for the segment.

Due to the relatively large tilt angle of the satellite, as the satellite moves, the transmission distance of the signal transmitted by the satellite to the terminal will change faster. Therefore, it is necessary to synchronize more frequently based on the transmission distance (such as compensating for timing advance). Therefore, the transmission duration for each segment can be set relatively small to synchronize more frequently for each segment, and correspondingly, the smaller the tilt angle of the satellite, the longer the transmission duration for the segment can be. Therefore, the correlation can include a negative correlation between tilt angle and transmission duration for segment. The network-side device may configure the correlation to the terminal. For example, via the configuration information.

The terminal can determine the ephemeris information of the current satellite. For example, they are based on the information broadcast by the satellite, such that a transmission duration, corresponding to each segment, in the plurality of candidate transmission durations is determined based on current ephemeris information and the correlation.

For example, the correlation between tilt angle in ephemeris information and transmission duration includes an angle A corresponding to a transmission duration T1, and an angle B corresponding to a transmission duration T2. Therefore, when determining that the tilt angle in the ephemeris information of the current satellite is the angle A, the transmission duration T1 corresponding to the angle A can be determined from the candidate transmission durations as the transmission duration for each segment.

If the tilt angle of angle C in the ephemeris information of the current satellite does not exist in the correlation, the terminal can determine an angle closest to the angle C in the correlation, such as the angle B, and thus determine the transmission duration T2 corresponding to the angle B as a transmission duration for each segment.

In an embodiment, the method further includes: determining, based on the terminal, a transmission duration, corresponding to each segment, in the plurality of candidate transmission durations.

The terminal can not only determine the transmission duration for each segment from the candidate transmission durations according to the correlation between ephemeris information and transmission duration, but also select one of the candidate transmission durations as the transmission duration from each segment according to the terminal itself.

FIG. 9 is a flowchart illustrating a capability determination method according to an embodiment of the present disclosure. The capability determination method shown in this embodiment can be performed by a network-side device, which can communicate with a terminal. The network-side device includes, but is not limited to, a base station (such as a 4G base station, a 5G base station, a 6G base station and the like) in a communication system. The terminal includes, but is not limited to, a communication device such as a mobile phone, a tablet, a wearable device, a sensor, and an IoT device.

As shown in FIG. 9, the method may include the following steps S901 to S902.

At step S901, capability indication information transmitted by a terminal is received.

At step S902, a capability of the terminal to support uplink transmission timing advance pre-compensation for segment-based transmission is determined based on the capability indication information.

In an embodiment, the terminal may determine its own capability to support the uplink transmission timing advance pre-compensation for segment-based transmission, and the capability includes supporting the uplink transmission timing advance pre-compensation for segment-based transmission, and not supporting the uplink transmission timing advance pre-compensation for segment-based transmission. Further, the capability indication information is transmitted to the network-side device, and the network-side device may determine, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission. For example, the network-side device can determine whether the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission or not.

FIG. 10 is a flowchart illustrating a capability determination method according to another embodiment of the present disclosure. As shown in FIG. 10, the determining, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission includes:

At step S1001, that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission is determined based on the capability indication information;

- where the method further includes:

At step S1002, that the terminal supports puncturing or dropping overlapping portions of a plurality of segments based on a first time domain granularity is determined based on the capability indication information.

In an embodiment, the first time domain granularity includes at least one of:

- a time domain symbol, a time slot, or a subframe.

Illustrated by the example of the embodiment shown in FIG. 3, the portion of the pre-compensated segment 2 overlapping with the segment 1 corresponds to six time domain symbols. When the first time domain granularity is a time domain symbol, it may determine that the terminal punctures or drops only the overlapping portion of the segment 2. When the first time domain granularity is a time slot, it may determine a time slot in which the six time domain symbols are located, and thus further determine that the terminal punctures or drops the information of the segment 2 in this time slot. When the first time domain granularity is a subframe, it may determine a subframe in which the six time domain symbols are located, and thus further determine that the terminal punctures or drops the information of the segment 2 in this subframe.

FIG. 11 is a flowchart illustrating a capability determination method according to yet another embodiment of the present disclosure. As shown in FIG. 11, the determining, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission includes:

At step S1101, that the terminal does not support the uplink transmission timing advance pre-compensation for segment-based transmission is determined based on the capability indication information;

- where the method further includes:

At step S1102, scheduling, based on a scheduling instruction with a transmission duration greater than a preset duration, the terminal is stopped.

In an embodiment, when the terminal determines that the uplink transmission timing advance pre-compensation for segment-based transmission is not supported, the uplink transmission carried out in general is no longer than a preset time length in the time domain, so that the transmission time length corresponding to the uplink transmission is not too large, e.g., not larger than the preset time length. Therefore, the terminal cannot expect to receive a scheduling instruction with a transmission duration greater than the preset duration. Accordingly, the network-side device may stop scheduling, based on a scheduling instruction with a transmission duration greater than a preset duration, the terminal.

FIG. 12 is a flowchart illustrating a capability determination method according to yet another embodiment of the present disclosure. As shown in FIG. 12, the method further includes the following steps S1201 to S1202.

At step S1201, the segment-based transmission is configured for the terminal.

At step S1202, segments transmitted by the terminal and/or a portion of the segments within the preset duration is received.

Therefore, even if there is a first segment with a transmission duration greater than the preset duration, for the first segment, only the portion within the preset duration range of the first segment is transmitted. For example, only the portion of the first segment that continues for the preset duration from the starting time domain position is transmitted. Accordingly, problems arising from uplink transmission in excess of the capability of the terminal can be avoided. Correspondingly, the network-side device can only receive the portion of the first segment within the preset duration.

FIG. 13 is a flowchart illustrating a capability determination method according to yet another embodiment of the present disclosure. As shown in FIG. 13, the determining, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission includes:

At step S1301, that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission is determined based on the capability indication information.

- where the method further includes:

At step S1302, configuration information is transmitted to the terminal, where the configuration information is used to configure a transmission duration for each of a plurality of segments of uplink transmission.

In this case, the terminal can divide the uplink transmission into a plurality of segments, and the network-side device can transmit configuration information to the terminal, and configure a transmission duration for each segment based on the configuration information for the terminal, accordingly, the terminal can determine the transmission duration for each segment according to the transmission duration in the configuration information.

In an embodiment, the determining, based on the capability indication information, the capability of the terminal to support the uplink transmission timing advance pre-compensation for segment-based transmission includes:

- determining, based on the capability indication information, that the terminal supports the uplink transmission timing advance pre-compensation for segment-based transmission;
- where the method further includes:
- transmitting configuration information to the terminal, where the configuration information includes a plurality of candidate transmission durations, and the configuration information is used to configure a correlation between ephemeris information and transmission duration.

In an embodiment, there may be a correlation between ephemeris information and transmission duration for segment. For example, specifically there may be a correlation between tilt angle in ephemeris information and transmission duration for segment.

The terminal can determine the ephemeris information of the current satellite. For example, based on the information broadcast by the satellite, such that a transmission duration, corresponding to each segment, in the plurality of candidate transmission durations is determined based on current ephemeris information and the correlation.
