The network device 103 in the embodiment of the present application also includes a device that provides a base station function in a new communication system in the future, and the like.

The embodiment of the application defines a unidirectional communication link from an access network to UE as a Downlink (DL) and data transmitted on the Downlink as Downlink data, wherein the transmission direction of the Downlink data is called as a Downlink direction; and the unidirectional communication link from the UE to the access network is Uplink (UL for short), the data transmitted on the Uplink is Uplink data, and the transmission direction of the Uplink data is called Uplink direction.

With the rapid increase of uplink service demands, higher demands are put forward on uplink coverage rate, speed and time, and the full duplex technology can simultaneously transmit uplink and downlink at the same time, so that opportunities are provided for enhancing uplink services compared with the existing Time Division Duplex (TDD) system which is more focused on downlink transmission.

For a better understanding of the embodiments of the present application, reference is made to fig. 2a to 2d, and fig. 2a to 2d are schematic diagrams of several transmission resource configurations provided in the embodiments of the present application.

In fig. 2a to 2D, "D" represents a downlink subband and "U" represents an uplink subband.

The full duplex of the sub-band divides the frequency domain resource into different sub-bands at the base station side, and the different sub-bands simultaneously and respectively perform downlink transmission and uplink reception, and still supports half duplex for the UE, and only downlink reception can be performed in the downlink sub-band or uplink transmission can be performed in the uplink sub-band at a certain time point.

In the existing standard, the timeslot configuration of all Bandwidth parts (BWP) in the same cell is the same for the UE, that is, the UE considers that downlink reception or uplink transmission can be performed at any frequency domain position of the whole BWP at a certain moment.

In the full duplex of the sub-band, the sending and receiving of the dynamic scheduling can be performed through the frequency domain resources appointed by the base station, so that the uplink and downlink conflict can not occur; for periodic or semi-static transmission, the base station cannot instruct to transmit/receive the frequency domain resource in real time, and at a certain moment, the UE may use the downlink sub-band frequency domain resource to perform periodic or semi-static uplink transmission because the UE does not know the sub-band and the time slot information in the sub-band, thereby affecting the downlink reception of other UEs; in addition, the UE may also perform periodic or semi-static downlink reception on the uplink sub-band, resulting in the failure to receive the desired signal.

Wherein BWP is a subset bandwidth of the total bandwidth of the serving cell, which flexibly adjusts UE reception and transmission bandwidth size through bandwidth adaptation in NR, so that UE reception and transmission bandwidths do not need to be as large as the bandwidth of the cell. For example: 1) When the UE is in a low activity period, the gNB may instruct to reduce the Bandwidth (BWP) of the UE through higher layer signaling or DCI, and may save the power of the UE at this time; 2) The gNB indicates that the location of BWP can be moved in the frequency domain, thus increasing the flexibility of scheduling; 3) The gNB may instruct the UE to change the subcarrier spacing and thus may allow different services.

Illustratively, in the existing standard protocol, the gNB broadcasts the unique semi-static uplink and downlink slot configuration for the cell in system information block type1 (System Information Block type, SIB1 for short). Two slot patterns (patterns) may be included in the slot configuration period, and each pattern may include UL, DL, and flexible (flexible) slots (slots)/symbols (symbols), where each pattern has an nrofdownslots (number of full downlink slots) +nrofdownslots (number of downlink symbols after full downlink slots), and an nrofupslots (number of uplink symbols before full uplink slots) +nrofupslots (number of full uplink slots) at the beginning, and the remaining slots without configuration are flexible slots/symbols.

After the UE enters the connection state, the gNB may configure a semi-static timeslot configuration similar to the cell level broadcast by SIB1, or reconfigure a semi-static uplink and downlink timeslot configuration or a dynamic uplink and downlink timeslot configuration of the UE level for each UE, but the UE level timeslot configuration cannot change the configuration of the cell level UL and DL slot/symbol, and only flexible slot/symbol can be configured as UL or DL. In the UE-level semi-static slot configuration, the entire slot may be configured to be uplink or downlink with the slot as granularity, or the designated slot may be configured with the symbol as granularity, i.e., the slot starts with nrofDownlinkSymbols downlink symbols and ends with nrofUplinkSymbols uplink symbols. When the uplink and downlink time slot configuration is performed in a dynamic manner, specific uplink and downlink configuration can be performed for each symbol in each time slot from the symbol level.

The above slot configuration is configured based on the whole BWP, that is, for one UE, the whole BWP is DL/UL/flexible, that is, one UE will transmit or receive on the whole BWP resource. The full duplex of the sub-band needs to transmit/receive on the uplink/downlink frequency domain sub-band, and for the transmission and the reception of the dynamic scheduling, the transmission and the reception can be performed through the frequency domain resources appointed by the base station, so that the uplink/downlink conflict can not occur; for periodic or semi-static transmission, the base station cannot instruct the transmission/reception frequency domain resources in real time, which may cause the collision of the transceiving resources of different terminals.

In view of the above technical problems, an embodiment of the present application provides a method and an apparatus for configuring a timeslot, where the timeslot configuration is performed for each subband, and subband timeslot information is notified to a UE through RRC and/or DCI, so that the UE can obtain the subband timeslot configuration on the entire serving cell or the subband timeslot configuration on the entire BWP, and further transmit and receive on corresponding uplink/downlink subbands; since the UE can know the sub-band slot configuration on the entire serving cell or the sub-band slot configuration on the entire BWP, it is possible to fully use all available resources and avoid collision of uplink and downlink transmissions. The following will explain in detail the embodiments.

Referring to fig. 3, fig. 3 is a flowchart of a time slot configuration method according to an embodiment of the present application, where the time slot configuration method may be applied to a UE, and the UE is in a sub-band full duplex mode.

Alternatively, the above method for configuring timeslots may be performed by the UE, or may be performed by a chip or a specific module in the UE, which is not limited in the embodiment of the present application.

In one possible embodiment, the method comprises:

Wherein the slot structure is configured with a cell-level and a UE-level division, wherein the cell-level configuration is configured by the IE TDD-UL-DL-configuration command, and for UE-level dedicated slots, indicated by TDD-UL-DL-configuration defined.

For better understanding of the embodiments of the present application, referring to fig. 4, fig. 4 is a schematic diagram comparing the existing standard timeslot configuration mode with the sub-band timeslot configuration mode provided by the embodiments of the present application.

According to the time slot configuration method provided by the embodiment of the application, as the UE can know the sub-band time slot configuration on the whole cell or the sub-band time slot configuration on the whole BWP, the UE can perform uplink and downlink transmission on the corresponding frequency domain resources, can furthest utilize all available frequency domain resources, and avoids conflict of the uplink and downlink frequency domain resources.

In some embodiments, when the sub-band full duplex mode is configured in the serving cell, the UE determines, according to the time slot configuration information of the sub-band where the UE is currently located, a time slot configuration of the sub-band used by the UE; when the sub-band full duplex mode is configured in the BWP, the UE determines a slot configuration of the sub-band used by the UE according to slot configuration information of each sub-band currently in the BWP.

Based on what is described in the above embodiments, in some embodiments, the network device may configure UE-level subband slot information in RRC as follows.

For example, an IE TDD-UL-DL-configuration Dedimidedsuband may be added under ServerCellConfig to configure the UE-level semi-static slot configuration of each subband in TDD mode, which if present, would overwrite TDD-UL-DL-configuration Dedimidedsuband. In some embodiments, the TDD-UL-DL-configuration de-allocation subbands comprises 1 to maxNrofSubbands TDD-UL-DL-confgde-allocation subbands, wherein the maxNrofSubbands are the total number of subbands on the serving cell if the full duplex subband information is defined on the serving cell; if full duplex subband information is defined on BWP, the maxnrof subbands is the total number of subbands on this BWP.

In some embodiments, the TDD-UL-DL-confeded subband is added with an IE subband id to the IE TDD-UL-DL-confeded to indicate which subband the configured slot belongs to, with a value ranging from 0 to maxnrofubband-1. If full duplex subband information is defined on the serving cell, the subband id value is defined on the serving cell; if full duplex subband information is defined on BWP, this subband id value is defined on BWP. Thus, the UE-level semi-static slot configuration can be defined for the sub-bands by tdd-UL-DL-configuration DediocatedSubband.

In some embodiments, the network device may configure a subband slot format combination (slot format combination) in RRC by selecting one from the above slot format combinations as the subband slot configuration by DCI 2_0. The following describes how to configure the subband slot format combination by RRC:

in one possible implementation, an ieslotgormamcombtoaddmodlist-subbands may be added to the slot format indicator, which contains 1 to maxnofsubband groups cells per cell group of slot format combinations available for each subband, with a length of 1 to maxnofsubband groups of cells per cell group.

In some embodiments, if full duplex subband information is defined on a serving cell, maxnrof subband aggregatedcellspercellgroup represents the total number of subbands on all serving cells in the primary serving cell group (PCG); if full duplex subband information is defined on BWP, maxnrof subband aggregatedcellspercellgroup represents the sum of all the numbers of subbands on all BWP on all serving cells in PCG.

In some embodiments, if full duplex subband information is defined on a serving cell, slotgormatCombition Percell-subbands defines a possible slot format combination for a subband on a certain serving cell, slotgormatCombition Percell-subbands is increased by one IE subband Id relative to slotgFormat Combition Percell to indicate which subband of which serving cell this slot format combination applies; if full duplex subband information is defined on BWP, slotgformative combination cells-subbands define a possible slot format combination for a subband on a BWP on a certain serving cell, slotgformative combination cells-subbands are added by two IEs, one being BWPId and the other being subband id, to indicate which subband under which BWP of which serving cell this slot format combination is applicable.

In the conventional technology, the Slot format indicator field of DCI 2_0 is used to indicate which index of a slot format combination in RRC is selected by a certain serving cell of the UE, and the number of Slot format indicator is the number of slotgormattcombtoaddmodlist configurations in RRC, and the position of DCI 2_0 is indicated by the position DCI under each serving cell slottformattcombinesspercell in RRC.

In some embodiments of the present application, the subband slot configuration of the UE is indicated by DCI 2_0.

If full duplex subband information is defined on the serving cell, the Slot format indicator field in DCI 2_0 indicates which index of the slot format combination in RRC is selected for a certain subband under a certain serving cell of the UE. The number of Slot format indicator is the number of slotgormattcombtoaddmodlist-subbands configured in RRC, and the position of DCI 2_0 is indicated by the position DCI under the corresponding subband slotgormattcombo percell-subbands in the corresponding serving cell in RRC.

If full duplex subband information is defined on BWP, slot format indicator field in DCI 2_0 indicates which index of slot format combination in RRC is selected for a certain subband of a certain BWP under a certain serving cell of UE. The number of Slot format indicator is the number of slotgormattcombtoaddmodlist-subbands configured in RRC, and indicated in the position of DCI 2_0 by the positionDCI under slotgormattcombineschcell-subbands corresponding to BWP in the corresponding serving cell in RRC.
