Description

Flexible duplex SBFD information indication method, terminal and network side equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a flexible duplex SBFD information indication method, a terminal and network side equipment.

Background

When the cellular network is deployed, based on available spectrum, traffic characteristics, and the like, a duplex mode such as frequency division duplex (Frequency Division Duplex, FDD) or time division duplex (Time Division Duplex, TDD) may be employed. When FDD is adopted, uplink transmission and downlink transmission are located on different frequency points, and the uplink transmission and the downlink transmission are not interfered with each other and can be performed simultaneously. When TDD is adopted, the uplink transmission and the downlink transmission are positioned on the same frequency point and are staggered in a time division mode. In order to more flexibly utilize limited spectrum resources to dynamically match service requirements and improve resource utilization efficiency, a flexible duplex (SBFD) mode is provided. The flexible duplex mode is as follows: full duplex at network side, that is, at the same time, uplink transmission and downlink transmission can be performed at different frequency domain positions simultaneously, and in order to avoid interference between uplink and downlink, a certain guard band can be reserved between frequency domain positions (corresponding to duplex sub-bands) corresponding to different transmission directions; terminal side half duplex, that is, the same as TDD, can only make uplink transmission or downlink transmission at the same time, and the two can not be made simultaneously. It will be appreciated that in this duplex mode, the uplink and downlink transmissions at the same time on the network side can only be directed to different terminals.

When the terminal performs uplink or downlink transmission based on the SBFD method, it is necessary to acquire SBFD related information, so how the terminal obtains the SBFD related information, for example, subband information, is a problem that needs to be solved by those skilled in the art.

and a plurality of DCIs, wherein different DCIs in the plurality of DCIs are used for indicating to activate the SBFD configuration information or deactivate the SBFD configuration information.

Optionally, in the case that the first indication information is carried by DCI that does not schedule data transmission, the DCI is a group common DCI, including at least one of the following cases:

and the plurality of DCIs are used for indicating whether the SBFD configuration information is effective or not in a detection period corresponding to the DCIs.

In an alternative embodiment, the SBFD configuration information may be configured/provided by higher layer signaling.

Whether the first indication information is to be followed or applied is indicated, for example, by DCI, either of the following ways may be employed:

Indication mode 1: the first indication information is carried by downlink control information DCI for scheduling data transmission; the first indication information is used for indicating at least one of the following:

the validation time information of the SBFD configuration information.

Specifically, the DCI for scheduling data transmission indicates whether the Override SBFD configuration information, whether mapping and/or occupancy within the SBFD time-domain unit is allowed, etc.;

optionally, the scheduled data transmission comprises: scheduled shared channel transmission, and/or triggered channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS)/sounding Reference Signal (Sounding Reference Symbol, SRS) transmission; any transmission in this DCI that is indicated to be applied and scheduled by this DCI (i.e. including/involving any transmission that satisfies both (1) being scheduled by this DCI and (2) applying the indication in this DCI), is subsequently referred to as a dynamically scheduled transmission.

Alternatively, in the following embodiment, namely Case 1-1: in case of simultaneous configuration/provision of time-frequency domain sub-band (Subband) configuration by higher layer signaling, i.e. comprising time-domain and frequency-domain resource information:

It is understood that for a certain sub-band (first sub-band), its resource information (e.g. including a location and/or a boundary) in both time and frequency domains is configured by higher layer signaling. Alternatively, for a configured Subband, its corresponding transmission direction may also be determined, e.g. as configured directly by higher layer signaling or as specified by a protocol or by default.

When the DCI indicates Override SBFD configuration information (e.g., allows dynamically scheduled transmissions to ignore and/or Override SBFD configuration information), the corresponding operations may be performed separately, as follows:

case 1-1: when the dynamically scheduled transmission overlaps with the first sub-band in the opposite direction, at least one of the following a1-a2 is performed:

a1, any Resource Element (RE) occupied by dynamically scheduled transmission in a first sub-band is Valid;

it is understood that any RE occupied in the first sub-band may actually map the physical signal corresponding to the dynamically scheduled transmission.

a2, the first sub-band is rewritten to the direction corresponding to the dynamically scheduled transmission in any time domain unit (e.g., slot or Symbol) that overlaps.

It will be appreciated that when the direction of the higher-layer configured transmission corresponds to the dynamically scheduled transmission, any RE of the time-domain unit in which the transmission falls in the first sub-band is determined to be Valid (Valid) (when the RE corresponding to the transmission satisfies a predefined requirement, for example, all REs corresponding to the transmission are determined to be Valid, the transmission may be determined to be Valid, and the terminal may perform the transmission, i.e., initiate the uplink transmission or receive the downlink transmission).

"first subband in opposite direction" can be understood as: for a certain Subband configured by higher layer signaling, the transmission direction specified by the higher layer signaling directly or by a protocol or by default is different from the transmission direction corresponding to the dynamically scheduled transmission, that is, opposite, for example, the transmission direction corresponding to the dynamically scheduled transmission is uplink, and the transmission direction of the first Subband is downlink.

"dynamically scheduled transmission overlaps with the first sub-band in the opposite direction" can be understood as: for a first sub-band in a certain opposite direction, at least one RE occupied by a certain dynamically scheduled transmission is located in a time-frequency resource range corresponding to the first sub-band in the opposite direction.

Optionally overlapping with the same direction of Subband does not affect the validity judgment of the transmission.

Cases 1-2: when the dynamically scheduled transmission does not overlap with the reverse direction Subband, the dynamically scheduled transmission can be considered as Valid;

it is understood that there is no actual Override behavior at this point, or the terminal may ignore the indication in the DCI. Accordingly, the terminal may directly perform the dynamically scheduled transmission, i.e., initiate the dynamically scheduled uplink transmission or receive the dynamically scheduled downlink transmission.

When a dynamically scheduled transmission configures/indicates a repeat transmission (Transport Block processing over multi-slot PUSCH, TBoMS), it may be determined whether case 1-1 or case 1-2 is satisfied for each (Nominal/Actual) repeat transmission corresponding to this dynamically scheduled transmission, respectively, and a corresponding operation is performed.

Optionally, when the DCI indicates that the Override SBFD configuration information is not available (e.g., the dynamically scheduled transmission is not allowed to ignore and/or the Override SBFD configuration information is not allowed), any of the following operations 1-1, 1-2, 1-3 may be performed:

operation 1-1: when the dynamically scheduled transmission overlaps with the first sub-band in the opposite direction, any RE occupied by the dynamically scheduled transmission in the first sub-band is determined to be Invalid (i.e., the terminal may consider any RE occupied by the dynamically scheduled transmission in the first sub-band Invalid), optionally, the terminal may perform Rate matching (Rate matching) or Puncturing (Puncturing) for the Invalid RE when performing this dynamically scheduled transmission.

When the dynamically scheduled transmission does not overlap with the first sub-band, the terminal may directly perform the dynamically scheduled transmission, i.e. initiate the dynamically scheduled uplink transmission or receive the dynamically scheduled downlink transmission, based on the time-frequency resources configured/indicated for the dynamically scheduled transmission.

Operations 1-2: when the dynamically scheduled transmission overlaps the first sub-band, the dynamically scheduled transmission is determined as Invalid, and the terminal does not perform the dynamically scheduled transmission.

Operations 1-3: the terminal does not expect the dynamically scheduled transmission to overlap with the first sub-band.

When DCI is used as an active DCI to activate a Semi-Persistent scheduling (SPS) physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission/Configuration Grant (CG) physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission/PUSCH transmission for carrying Semi-Persistent (SP) channel state information CSI, a terminal does not expect a first PDSCH transmission/PUSCH transmission corresponding to the DCI to overlap with a first sub-band in the opposite direction.

When a dynamically scheduled transmission configures/indicates a Repetition/TBoMS transmission, operations 1-1, 1-2, and/or 1-3 may be performed for each (Nominal/Actual) Repetition transmission corresponding to this dynamically scheduled transmission, respectively. Alternatively, for operation 1-1, when a certain (Nominal/Actual) Repetition transmission overlaps with the first sub-band in the opposite direction, the terminal may perform a segment operation for this (Nominal/Actual) Repetition transmission based on the time-domain unit in which the Invalid RE is located (specific operation may refer to the segment operation introduced for PUSCH Repetition Type B in Rel-16 Ultra high reliability low latency communication (URLLC)).

In the following embodiment, namely Case 1-2: in the case where only the time domain SBFD configuration is configured/provided by higher layer signaling (i.e., the SBFD configuration information includes only the time domain resource information of the SBFD):

it will be appreciated that higher layer signaling only configures which time domain unit(s) (e.g., time slots or Symbol) in which network side devices are expected and/or intended to perform SBFD operations, which may be referred to as SBFD time domain units. The SBFD time-domain unit may be configured and/or indicated as DL, UL and/or Flexible based on TDD mode (pattern) information including TDD-UL-DL-ConfigCommon and/or TDD-UL-DL-configdediated configured by higher layer signaling and/or a slot format indication (Slot Format Indicator, SFI) indicated by DCI format 2_0; in the case of DL and/or UL, the transmission direction may be the same or different from the direction corresponding to the dynamically scheduled transmission.

At this time, DCI may be used to indicate whether or not a resource mapping/occupation corresponding to a dynamically scheduled transmission is allowed within the SBFD time domain unit.

When the DCI indicates that resource mapping/occupation is allowed (e.g., mapping and/or occupation of resources corresponding to transmission that is allowed to be dynamically scheduled within the SBFD time domain unit), the following cases (case 2-1, case 2-2) may be distinguished to perform corresponding operations, respectively.

Case 2-1: when the dynamically scheduled transmission overlaps with the SBFD time-domain unit, at least one of the following b1-b3 is performed:

b1, any RE occupied by the dynamically scheduled transmission in the overlapped SBFD time domain unit is judged to be valid;

it is understood that these REs may actually map physical signals corresponding to dynamically scheduled transmissions.

b2, any overlapped SBFD time domain unit is rewritten into a direction corresponding to the dynamically scheduled transmission;

it can be appreciated that when the direction of the higher-layer configured transmission corresponds to the dynamically scheduled transmission is the same, any RE in which this transmission falls within the overlapping SBFD time-domain unit is determined to be Valid; for example, when the RE corresponding to the transmission meets a predefined requirement, e.g., all REs corresponding to the transmission are determined to be Valid, the transmission may be determined to be Valid, and the terminal may perform the transmission, i.e., initiate the uplink transmission or receive the downlink transmission.

b3, applying configuration information for the SBFD time domain unit for any RE occupied by the dynamically scheduled transmission in the overlapped SBFD time domain units.

"configuration information for SBFD time-domain unit" can be understood as: for certain physical Channel/Signal transmission (for example, PUSCH/physical uplink control Channel (Physical Uplink Control Channel, PUCCH)/physical random access Channel (Physical Random Access Channel, PRACH)/SRS transmission, or PDSCH/CSI-RS transmission), the network side device may independently configure configuration information applied to the SBFD time domain unit in addition to corresponding conventional Legacy (for example, standard protocol Rel-15/16/17) configuration information; the configuration information herein may be understood as a single or multiple configuration parameters, or a subset of configuration parameters, or a Config object (e.g. PUSCH-Config, PDSCH-Config, etc.), etc.

Optionally, when the overlapping SBFD time-domain units meet a predefined first condition, the terminal applies configuration information for the SBFD time-domain units for this dynamically scheduled transmission (unified for each RE occupied), otherwise the terminal applies Legacy configuration information for this dynamically scheduled transmission. The first condition herein includes at least one of:

Case 2-2: when the dynamically scheduled transmission does not overlap with the SBFD time domain unit, the dynamically scheduled transmission is determined to be valid;

it is understood that there is no extra/different behavior, i.e. with respect to Legacy dynamic scheduling.

It is understood that the indication in the DCI is not valid at this time, or the terminal may ignore the indication in the DCI. Accordingly, the terminal may directly perform the dynamically scheduled transmission, i.e., initiate the dynamically scheduled uplink transmission or receive the dynamically scheduled downlink transmission.

When a dynamically scheduled transmission configures/indicates a Repetition/TBoMS transmission, it may be determined whether case 2-1 or case 2-2 is satisfied for each (Nominal/Actual) Repetition transmission corresponding to this dynamically scheduled transmission, respectively, and a corresponding operation is performed.

When the DCI indicates that resource mapping/occupation is not allowed (i.e., mapping and/or occupation of resources corresponding to dynamically scheduled transmission within the SBFD time domain unit is not allowed), any one of the following operations 2-1, 2-2, 2-3 may be performed:

operation 2-1: when the dynamically scheduled transmission overlaps with the SBFD time domain unit, any RE occupied by the dynamically scheduled transmission in the SBFD time domain unit is judged to be Invalid Invalid, i.e. the terminal can consider any RE occupied by the dynamically scheduled transmission in the SBFD time domain unit to be Invalid; optionally, when the terminal performs the dynamically scheduled transmission, the Rate matching or Puncturing processing may be performed for the Invalid RE.

When the dynamically scheduled transmission does not overlap with the SBFD time domain unit, the terminal may directly perform the dynamically scheduled transmission based on the time-frequency resources configured/indicated for the dynamically scheduled transmission, i.e. initiate the dynamically scheduled uplink transmission or receive the dynamically scheduled downlink transmission.

Operation 2-2: when the dynamically scheduled transmission overlaps with the SBFD time-domain unit, the dynamically scheduled transmission is determined as Invalid, i.e., the terminal may consider the dynamically scheduled transmission of the terminal Invalid and not execute the dynamically scheduled transmission.

Operation 2-3: the terminal does not expect the dynamically scheduled transmission to overlap with the SBFD time-domain unit.

Optionally, when DCI is used as the active DCI for activating SPS PDSCH transmission/CG PUSCH transmission/PUSCH transmission for carrying SP CSI, the UE does not expect the first PDSCH transmission/PUSCH transmission corresponding to this DCI to overlap with the SBFD time-domain unit.

Alternatively, when the dynamically scheduled transmission configures/indicates a Repetition/TBoMS transmission, operations 2-1, 2-2, 2-3 may be performed for each (Nominal/Actual) Repetition transmission corresponding to this dynamically scheduled transmission, respectively. Alternatively, for operation 2-1, when a certain (Nominal/Actual) Repetition transmission overlaps with the SBFD time-domain unit, the terminal may perform a Segmentation operation for this (Nominal/Actual) Repetition transmission based on the time-domain unit in which the Invalid RE is located (for a specific operation reference may be made to the Segmentation operation introduced for PUSCH Repetition Type B in Rel-16 URLLC).

For Case 1-2 described above, optionally, the DCI may indicate whether to allow resource mapping/occupation corresponding to dynamically scheduled transmission in a time domain unit other than the SBFD time domain unit and having a transmission direction opposite to that of the dynamically scheduled transmission determined based on the TDD pattern information, in addition to indicating whether to allow resource mapping/occupation corresponding to dynamically scheduled transmission in the SBFD time domain unit. The two indications may be indicated in a unified manner by the same information/mode in the DCI, or may be indicated independently by different information/modes in the DCI.

For Case 1-1 and Case 1-2 described above, the indication in the dci may be any one of the following indication modes 1-1 and 1-2:

indication mode 1-1: indication is carried out by an independent indication domain in DCI;

alternatively, the indication field in the DCI may be configured by higher layer signaling whether it exists, and when it does not exist, an indication value or operation specified by the higher layer configuration or protocol is applied (e.g., for Case 1-1 described above, when the indication field does not exist in the DCI, no Override SBFD configuration; for Case 1-2 described above, resource mapping/occupation is not allowed when the indication field does not exist in the DCI), and when it exists, at least one bit may be occupied.

For DCI detected within a Type0/0A/1/2/2A-PDCCH common search space (Common Search Space, CSS) SET and/or DCI detected within a certain PDCCH search space SET associated with a COntrol REsource SET (core-reference SET, core) #0 and/or DCI scrambled by a specific radio network temporary identity (radio network temporary identity, RNTI) (e.g., system information (System Information, SI) -/paging P-/random access RA-/temporary cell TC-RNTI), the scheduled transmission, the indication field in the DCI may not be present or the terminal may ignore the indication field in the DCI, at which point the indication value or operation specified by the higher layer configuration or protocol is applied.

Indication mode 1-2: performing joint coding with the existing indication domain in DCI;

optionally, a certain code (codepoint) of the joint indication domain (the number of occupied bits may be extended relative to the number of occupied bits of the existing indication domain as required) indicates both the information that needs to be indicated by the existing indication domain and the first indication information that needs to be indicated by the embodiment of the present application. For example, the existing indication field may be a frequency domain resource allocation (Fequency Domain Resource Allocation, FDRA) indication field.

Alternatively, when the DCI for scheduling data transmission schedules multiple types of physical Channel/Signal transmissions simultaneously (the direction of the transmission may be opposite to that of the dynamic scheduling), the indication in the DCI may be applied to any type of physical Channel/Signal transmission scheduled by the DCI, or one or more types of physical Channel/Signal transmissions to which the indication in the DCI is applied may be configured by higher-layer signaling or specified by a protocol. For example, for DCI format 1_1, a single DCI may schedule PDSCH transmissions and indicate PUCCH transmissions carrying hybrid automatic repeat request-acknowledgement HARQ-ACK feedback for these scheduled PDSCH transmissions, while SRS transmissions may also be triggered; for DCI format 0_1, a single DCI can schedule PUSCH transmission, can trigger corresponding CSI-RS transmission when triggering Aperiodic (Aperiodic) CSI reporting, and can trigger SRS transmission at the same time; the indication in the DCI may be applied only to scheduled PDSCH/PUSCH transmissions for these DCI format formats, either configured by higher layer signaling or specified by the protocol.

When a certain physical Channel/Signal transmission (e.g., PDSCH/PUSCH transmission, PUCCH transmission, PRACH transmission) in DCI indicates an application, a Repetition transmission is configured or indicated, or a TBoMS transmission scheme (e.g., for PUSCH transmission) is adopted, this indication may be applied to any (Nominal/Actual) Repetition transmission corresponding to this physical Channel/Signal transmission, or an nth (Nominal/Actual) Repetition transmission (e.g., first or last (Nominal/Actual) Repetition transmission) configured by higher layer signaling or specified by a protocol.

Alternatively, when DCI is used as the active DCI for activating SPS PDSCH transmission/CG PUSCH transmission/PUSCH transmission for carrying SP CSI, the indication in the DCI may be applied to the first PDSCH transmission/PUSCH transmission corresponding to this DCI or to any PDSCH transmission/PUSCH transmission corresponding to this DCI (before issuing the corresponding release DCI).

Alternatively, for Multi-PXSCH scheduling, when an indication in the DCI applies to a scheduled PXSCH transmission, this indication may apply to any one of the PXSCH transmissions scheduled, or an mth PXSCH transmission (e.g., first or last PXSCH transmission) configured by higher layer signaling or specified by a protocol.

Alternatively, the indication in the DCI for scheduling data transmission may also adopt an indication manner similar to the indication manner 2-1-1, that is, in addition to the Case 1-1 or the Case 1-2, the effective time information (including, for example, a start time, an end time, an effective duration, etc.) corresponding to the first indication information may be further indicated, which can be specifically described in the following embodiments.

Optionally, if the DCI indicates that the DCI is valid, the time domain range corresponding to the time-to-be-validated duration is expected by the terminal to cover at least any transmission (and/or time domain allocation) scheduled by the DCI and applying the first indication information in the DCI.

In the above embodiment, on the premise of acceptable implementation complexity (such as hardware), the flexibility of the SBFD operation is improved, so that the performance of time delay, throughput and the like of the SBFD is improved.

Indication mode 2: the first indication information is carried by DCI without scheduling data transmission, and the first indication information is used for indicating whether the SBFD configuration information takes effect and/or effective time information.

Optionally, the validation time information includes at least one of:

start time, end time, effective duration.

The method can be realized in at least one of the following indication modes 2-1 and 2-2:

Indication mode 2-1: using the terminal-specific DCI (UE specific DCI) that does not schedule data, any one of the following indication schemes 2-1-1 and 2-1-2 may be adopted:

indication mode 2-1-1: indicating by one DCI, i.e. indicating by one DCI whether SBFD configuration information is valid and/or validation time information;

specifically, whether to take effect and the time of effect information may be indicated separately or jointly. When indicated separately, it is possible, for example, to indicate whether the validity is valid by 1 bit, and the indicated validity time information is applied only when the validity is valid. When indicated jointly, one state of the joint indication field may indicate that it is not effective, and each of the other at least one state indicates a specific effective time information (for example, effective duration) when it is effective, respectively.

For example, the validation time information includes a validation time, and when the validation is indicated, a start time of the validation time may be a predefined time corresponding to the DCI, or a predefined time corresponding to the dci+a time corresponding to the predefined time 1. Here, the predefined time corresponding to DCI may be any one of the following:

start and/or end times of DCI reception;

the start/end time of the time domain unit (e.g., slot) where the DCI is received.

In other embodiments, the start and end times of the validation may be dynamically indicated.

Indication mode 2-1-2: multiple DCIs indicate, e.g., different DCIs indicate different information, and one DCI indicates only one information, e.g., one DCI indicates to turn on SBFD configuration (i.e., activate SBFD configuration information) and another DCI indicates to turn off SBFD configuration (i.e., deactivate SBFD configuration information).

Specifically, the DCI indicating to turn on the SBFD configuration may be referred to as SBFD configuration activation DCI; the DCI indicating to turn off the SBFD configuration may be referred to as an SBFD configuration release (or deactivation) DCI. Starting from a predefined time corresponding to the SBFD activation configuration DCI (or a predefined time corresponding to the SBFD activation configuration dci+a predefined time corresponding to a predefined duration 2), until a predefined time corresponding to the SBFD configuration release DCI (or a predefined time corresponding to the SBFD activation release dci+a predefined time corresponding to a predefined duration 3), the terminal considers that the SBFD configuration is in an active state (or considers that the SBFD configuration needs to be applied).

When the SBFD configuration is in an active state, its active transmission range may include at least one of: transmission of semi-static configuration; dynamically scheduled transmissions.

Optionally, the terminal may feed back the corresponding HARQ-ACK for the DCI, so as to avoid inconsistent understanding at both sides caused by missing DCI.

Indication mode 2-2: using group common DCI (Group common DCI), any of the following indication modes 2-1-1, 2-1-2 may be employed:

indication mode 2-1-2: indicated by a plurality of DCIs, i.e., each detected DCI indicates whether the SBFD configuration is valid for a particular configuration period;

alternatively, the period and offset corresponding to the search space for detecting DCI may be configured, and each DCI detected based on the configured period and offset indicates whether SBFD configuration information is valid in the corresponding period

In the above embodiment, on the premise of acceptable implementation complexity (such as hardware), the flexibility of the indication mode is relatively high, and the flexibility of the SBFD operation is improved, so that the performances of time delay, throughput and the like of the SBFD are improved.

In another alternative embodiment, when the SBFD configuration information is not configured/provided by higher layer signaling (i.e., the SBFD configuration information may also be implemented by dynamic indication) any of the following ways may be employed:

operation mode 1: SBFD configuration information, e.g. frequency format indication (Frequency Format Indicator, FFI), is indicated only by DCI (periodically); similar to SFI, but mainly focused on the format of the frequency domain;

Operation mode 2: directly based on network side scheduling, SBFD operation Alt (legacy) or SBFD operation Alt (dynamic scheduling transmission, may be override semi-static) TDD pattern) may be employed.

Alternatively, whether to allow resource mapping/occupation corresponding to the dynamically scheduled transmission in a time domain unit in which the transmission direction determined based on the TDD pattern information is opposite to the direction of the dynamically scheduled transmission may be indicated in DCI of the scheduled data transmission. The specific operation is similar to that in the foregoing embodiment, and will not be described here again.
