AI Technical Summary
The existing 5G NR system fails to distinguish different types of time slots in the determination of uplink transmission frequency resource, resulting in insufficient utilization of uplink transmission bandwidth and frequent BWP handover leading to waste of resources.
Different uplink bandwidth portions (BWPs) are configured for different types of time units, including time units that allow the base station to perform uplink reception and downlink transmission simultaneously, and time units that perform uplink reception only, and uplink transmission frequency resources are determined by instructing and switching activated BWPs.
The bandwidth of different types of time units is fully utilized for uplink transmission, which avoids interrupt time caused by frequent BWP handover, improves uplink transmission efficiency and reduces neighbor frequency interference.

Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, apparatus, electronic device, and storage medium for determining resources for uplink transmission. Background Art
[0002] Traditional duplex modes include Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD). In order to adapt to the time-varying and asymmetric service requirements of uplink and downlink, the current New Radio (NR) system of the 5th Generation mobile networks (5G) supports dynamic TDD to allow the base station to dynamically adjust the time slot ratio of uplink and downlink. In the future, the duplex mode will evolve towards full duplex.
[0003] In the implementation of sub-band full duplex in related technologies, to reduce the adjacent frequency interference between operators, in the downlink time slot of traditional TDD, the uplink transmission can only be located at the center position of the frequency band in the frequency domain. As a result, in different types of time slots, such as the time slot when the base station can simultaneously perform uplink reception and downlink transmission, and the time slot only for uplink reception, the bandwidth available for uplink transmission is different.
[0004] However, for the uplink transmission on a carrier in the NR system in related technologies, the bandwidth available for uplink transmission is the same in different time slots, and the determination of uplink transmission frequency resources does not distinguish different types of time slots. Therefore, the uplink transmission method in related technologies is not applicable to the situation where the bandwidths available for uplink transmission in different types of time slots are different.
[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments.
[0049] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor terminal devices and / or microcontroller terminal devices.
[0050] Figure 1 is a schematic diagram showing different implementations of full duplex according to an example.
[0051] Full-duplex communication can transmit uplink information and downlink information simultaneously on the same frequency band. According to whether the frequency resources used for the simultaneous transmission of uplink information and downlink information on the same frequency band overlap, it can be divided into the following implementations. Refer to Figure 1 : 1. Full duplex with non-overlapping frequency resources for uplink and downlink information. As shown in Figure (a), uplink transmission is performed at the frequency domain center of the TDD downlink time slot, also known as sub-band non-overlapping full duplex; 2. Full duplex with overlapping frequency resources for uplink and downlink information. As shown in Figure (b), uplink and downlink are transmitted simultaneously at the frequency domain center of the TDD downlink time slot, also known as sub-band overlapping full duplex, and Figure (c), uplink and downlink are transmitted simultaneously at any frequency domain position, also known as fully overlapping full duplex.
[0052] Among the different implementations of the above full duplex, Figure 1 In the manner of (a), uplink transmission is performed at the frequency domain center of the TDD downlink time slot, which has the following advantages and can thus be preferentially implemented: it can improve uplink coverage, increase uplink capacity, and reduce uplink transmission delay; uplink and downlink use different frequency resources, which is beneficial to the elimination of base station self-interference; placing transmissions in opposite directions at the center of the frequency band, the two sides of the frequency band can be regarded as guard bands, which is beneficial to reducing adjacent frequency interference between operators; if adjacent cells use the same uplink and downlink resource partitioning pattern, cross-link interference can be reduced.
[0053] In the embodiments of the present disclosure, full duplex can be preferentially implemented on the base station side, while the UE (User Equipment, also known as the terminal device) side can still maintain the traditional duplex mode. However, the present disclosure is not limited thereto. That is, the present disclosure does not limit whether the UE performs uplink and downlink transmissions simultaneously in a time unit, or can only transmit uplink or downlink. That is, the present disclosure is applicable to UEs that support or do not support simultaneous uplink and downlink transmissions.
[0054] The resource determination method for uplink transmission provided by the embodiments of the present disclosure can be applied to Figure 1 various full-duplex implementation manners shown below. In the following illustrative examples, the full-duplex implementation manner of Figure 1 (a) is taken as an example for illustration, but the present disclosure is not limited thereto. That is, the present disclosure does not limit whether the uplink and downlink transmissions overlap in frequency in the time unit when the base station can simultaneously perform uplink reception and downlink transmission. That is, the present disclosure is applicable to the case where the frequency resources of uplink transmission and downlink transmission do not overlap at the center of the frequency band of the downlink time slot in traditional TDD, and is also applicable to the case where the frequency resources of uplink transmission and downlink transmission overlap at the center of the frequency band of the downlink time slot in traditional TDD.
[0055] Next, each step of the resource determination method for uplink transmission in the exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings and embodiments.
[0056] Figure 2 is a flowchart of a resource determination method for uplink transmission shown according to an exemplary embodiment. The method provided by the embodiments of the present disclosure can be executed by a base station, but the present disclosure is not limited thereto.
[0057] As Figure 2 shown, the resource determination method for uplink transmission provided by the embodiments of the present disclosure may include the following steps.
[0058] In step S202, configure a first uplink BWP (Bandwidth Part) for a first time unit and a second uplink BWP for a second time unit. The first time unit is a time unit that allows the base station to simultaneously perform uplink reception and downlink transmission, and the second time unit is an uplink time unit.
[0059] In the embodiments of the present disclosure, the first time unit being a time unit that allows the base station to simultaneously perform uplink reception and downlink transmission means that the first time unit is a time unit when the base station can simultaneously perform uplink reception and downlink transmission. In the actual communication process, in the first time unit, the base station can simultaneously perform uplink reception and downlink transmission, the base station can also perform uplink reception alone, or the base station can also perform downlink transmission alone. The first time unit is the full-duplex time unit.
[0060] In the embodiments of the present disclosure, the second time unit is an uplink time unit, which means that the second time unit is a time unit that allows the base station to perform uplink reception and does not allow the base station to perform downlink transmission. In the actual communication process, in the second time unit, the base station only performs uplink reception and does not perform downlink transmission. The time unit in which the base station described in the embodiments of the present disclosure only performs uplink reception refers to the time unit that allows the base station to perform uplink reception and does not allow the base station to perform downlink transmission when the base station communicates with the terminal device, that is, the uplink time unit.
[0061] In the embodiments of the present disclosure, the first time unit may include a first time slot and / or a first symbol, and the second time unit may include a second time slot and / or a second symbol. In the following illustrative examples, the first time unit is taken as the first time slot and the second time unit is taken as the second time slot for illustration, but the present disclosure is not limited thereto.
[0062] For the uplink transmission of a traditional NR system on a carrier, the bandwidth available for uplink transmission is the same in different time slots, and the determination of uplink transmission frequency resources does not distinguish between different types of time slots:
[0063] In the case where there is no BWP switching on a carrier, uplink transmission in different time slots can only be performed based on the uplink channel and signal configuration corresponding to the only uplink working BWP. DCI (Downlink Control Information) can only indicate one BWP, and the domain of frequency domain resource allocation in DCI can only indicate the frequency domain resources in one BWP.
[0064] If the uplink working BWP is switched when switching between a time slot in which the base station can simultaneously perform uplink reception and downlink transmission and a time slot in which the base station only performs uplink reception, the working BWP switching is relatively frequent, and the resource waste is caused by the interruption delay of the UE working BWP switching.
[0065] Therefore, the uplink transmission method in the related art is not applicable to the case where the bandwidth available for uplink transmission is different for different types of time slots.
[0066] In the embodiments of the present disclosure, the base station may configure a first uplink BWP for the terminal device for the time slot in which the base station can simultaneously perform uplink reception and downlink transmission, and the base station may configure a second uplink BWP for the terminal device for the time slot in which the base station only performs uplink reception, so as to determine the uplink transmission frequency resources by configuring different uplink BWPs. The first uplink BWP and the second uplink BWP may have different frequency positions and / or sizes, so that the bandwidth available for uplink transmission in different types of time slots can be fully utilized for uplink transmission. Moreover, this method is applicable to the case where the bandwidth available for uplink transmission is different for the time slot in which the base station can simultaneously perform uplink reception and downlink transmission and the time slot in which the base station only performs uplink reception.
[0067] Figure 3 It is a schematic diagram of an uplink transmission mode shown according to an example.
[0068] Reference Figure 3 In the embodiments of the present disclosure, for the uplink transmission on a carrier, the base station may configure a set of uplink BWPs for the first time slot and the second time slot respectively, that is, configure a set of uplink BWPs for the first time slot and another set of uplink BWPs for the second time slot. Each set of uplink BWPs may include at least one of an initial BWP, a BWP set, a first activated BWP, and a to-be-activated BWP. The first activated BWP and the to-be-activated BWP can both be used as the activated BWP.
[0069] In an exemplary embodiment, the first uplink BWP may be a first initial uplink BWP and / or a first activated uplink BWP, and the second uplink BWP may be a second initial uplink BWP and / or a second activated uplink BWP.
[0070] In the embodiments of the present disclosure, the base station may configure the initial uplink BWP and the activated uplink BWP separately, or the base station may also configure the initial uplink BWP and the activated uplink BWP simultaneously.
[0071] Among them, both the above-mentioned initial uplink BWP and activated uplink BWP can be used as the uplink working BWP. After the UE enters the RRC (Radio Resource Control) connected state, the base station can configure the activated uplink BWP through RRC signaling, DCI or MAC (Medium Access Control) CE (Control Element). Before the UE enters the connected state, such as in the idle state or the random access process, at this time the UE has not obtained the configuration of the activated uplink BWP, and the initial uplink BWP can be used as the uplink working BWP.
[0072] In an exemplary embodiment, configuring the first uplink BWP for the first time unit and the second uplink BWP for the second time unit includes: configuring the first initial uplink BWP for the first time unit and the second initial uplink BWP for the second time unit.
[0073] In the embodiments of the present disclosure, the base station may configure the first initial uplink BWP for the time slot in which the base station can perform uplink reception and downlink transmission simultaneously through broadcast information, and the base station may configure the second initial uplink BWP for the time slot in which the base station only performs uplink reception through broadcast information.
[0074] In an exemplary embodiment, configuring a first uplink BWP for a first time unit and a second uplink BWP for a second time unit includes: configuring a first active uplink BWP for the first time unit and a second active uplink BWP for the second time unit.
[0075] In the embodiments of the present disclosure, for uplink transmission on a carrier, there can be 2 simultaneously active uplink BWPs, that is, there can be 2 working uplink BWPs of the UE, which are respectively used for the time slots when the base station can simultaneously perform uplink reception and downlink transmission, and the time slots for only uplink reception.
[0076] In an exemplary embodiment, configuring the first active uplink BWP can be configuring the first earliest active uplink BWP and / or configuring the first pending active uplink BWP, and configuring the second active uplink BWP can be configuring the second earliest active uplink BWP and / or configuring the second pending active uplink BWP.
[0077] In an exemplary embodiment, configuring a first active uplink BWP for a first time unit and a second active uplink BWP for a second time unit includes: configuring a first earliest active uplink BWP for the first time unit and a second earliest active uplink BWP for the second time unit.
[0078] In the embodiments of the present disclosure, the base station can configure the first earliest active uplink BWP for the first time slot and use the first earliest active uplink BWP as the first active uplink BWP; the base station can configure the second earliest active uplink BWP for the second time slot and use the second earliest active uplink BWP as the second active uplink BWP. For example, the base station can configure the first earliest active uplink BWP and the second earliest active uplink BWP for the terminal device through RRC signaling.
[0079] In an exemplary embodiment, configuring a first active uplink BWP for a first time unit and a second active uplink BWP for a second time unit includes: indicating the first pending active uplink BWP to switch the first active uplink BWP to the indicated first pending active uplink BWP; indicating the second pending active uplink BWP to switch the second active uplink BWP to the indicated second pending active uplink BWP.
[0080] In the embodiments of the present disclosure, the base station can indicate at least one of RRC signaling, MAC CE, and DCI an pending active BWP for the time slots when the base station can simultaneously perform uplink reception and downlink transmission. The base station can indicate at least one of RRC signaling, MAC CE, and DCI another pending active BWP for the time slots when the base station only performs uplink reception.
[0081] Among them, the BWP to be activated is used to activate the BWP handover. For different types of time slots, the currently activated BWP will be changed to at least one of the RRC signaling, MAC CE, and DCI to indicate the BWP to be activated for the corresponding time slot.
[0082] In an exemplary embodiment, indicating the first uplink BWP to be activated includes: indicating the first uplink BWP to be activated through the field for indicating the BWP in the first DCI; indicating the second uplink BWP to be activated includes: indicating the second uplink BWP to be activated through the field for indicating the BWP in the first DCI or the field for indicating the BWP in the second DCI; where the first DCI and the second DCI are sent separately.
[0083] In the embodiments of the present disclosure, the field for indicating the BWP in the DCI is used to indicate a BWP to be activated for the time slot when the base station can perform uplink reception and downlink transmission simultaneously, and is also used to indicate a BWP to be activated for the time slot when the base station only performs uplink reception.
[0084] In the embodiments of the present disclosure, the field for indicating the BWP in the DCI can simultaneously indicate two BWPs to be activated for different types of time slots.
[0085] Alternatively, in the embodiments of the present disclosure, the field for indicating the BWP in one DCI indicates a BWP to be activated for the time slot when the base station can perform uplink reception and downlink transmission simultaneously; the field for indicating the BWP in another DCI indicates another BWP to be activated for the time slot when the base station only performs uplink reception. Among them, the DCIs indicating the BWPs to be activated for different types of time slots are multiple DCIs that are not sent simultaneously. In an exemplary embodiment, the DCI (such as the first DCI and the second DCI) further includes discrimination information of the BWP application time unit, and the discrimination information of the BWP application time unit is used to discriminate whether the BWP to be activated indicated by the field for indicating the BWP in the DCI is for the time unit when the base station can perform uplink reception and downlink transmission simultaneously, or for the time unit when the base station only performs uplink reception, that is, the discrimination information of the BWP application time unit indicates the type of time unit to which the BWP to be activated indicated by the field for indicating the BWP in the DCI is applied.
[0086] In an exemplary embodiment, configuring the first uplink BWP for the first time unit and the second uplink BWP for the second time unit includes: configuring the first uplink BWP set for the first time unit and the second uplink BWP set for the second time unit, and both the first uplink BWP set and the second uplink BWP set include at least one uplink BWP.
[0087] In the disclosed embodiment, the base station may configure uplink BWP set 1 and uplink BWP set 2 through RRC signaling, wherein uplink BWP set 1 may be used for time slots in which the base station can simultaneously perform uplink reception and downlink transmission, and uplink BWP set 2 may be used for time slots in which the base station only performs uplink reception. One or more uplink BWPs may be configured in each set. In an exemplary embodiment, the first uplink BWP set does not include the first initial uplink BWP, and the second uplink BWP set does not include the second initial uplink BWP. The first uplink BWP set is also referred to as a set of first additional BWPs other than the first initial uplink BWP, and the second uplink BWP set is also referred to as a set of second additional BWPs other than the second initial uplink BWP.
[0088] In an exemplary embodiment, configuring a first uplink BWP for a first time unit and a second uplink BWP for a second time unit includes: configuring a first initial uplink BWP for the first time unit and a second initial uplink BWP for the second time unit, configuring a first activated uplink BWP for the first time unit and a second activated uplink BWP for the second time unit.
[0089] The configured first activated uplink BWP is an uplink BWP included in the first uplink BWP set, or the configured first activated uplink BWP and the first initial uplink BWP are the same BWP.
[0090] The configured second activated uplink BWP is an uplink BWP included in the second uplink BWP set, or the configured second activated uplink BWP and the second initial uplink BWP are the same BWP.
[0091] In the disclosed embodiment, the base station may indicate a BWP from uplink BWP set 1 as the first first activated uplink BWP, or indicate the first initial uplink BWP as the first first activated uplink BWP, through RRC signaling; the base station may indicate a BWP from uplink BWP set 2 as the second first activated uplink BWP, or indicate the second initial uplink BWP as the second first activated uplink BWP, through RRC signaling.
[0092] In the disclosed embodiment of the present invention, the base station may indicate a BWP from uplink BWP set 1 as the first uplink BWP to be activated, or indicate the first initial uplink BWP as the first uplink BWP to be activated, through at least one of RRC signaling, MAC CE, and DCI; the base station may indicate a BWP from uplink BWP set 2 as the second uplink BWP to be activated, or indicate the second initial uplink BWP as the second uplink BWP to be activated, through at least one of RRC signaling, MAC CE, and DCI.
[0093] The resource determination method for uplink transmission provided by the embodiments of the present disclosure configures different uplink BWPs for the first time unit that allows the base station to perform uplink reception and downlink transmission simultaneously and the second time unit that allows the base station to perform uplink reception but does not allow the base station to perform downlink transmission, so as to determine the uplink transmission frequency resources by configuring different uplink BWPs, thereby making full use of the bandwidth available for uplink transmission in different types of time units for uplink transmission. Moreover, this method can be applied to the situation where the bandwidth available for uplink transmission in different types of time units is different.
[0094] In addition, this method configures different uplink BWPs for different types of time units. For the uplink transmission on a carrier, the UE can have 2 working uplink BWPs, which are respectively used for the first time unit that allows the base station to perform uplink reception and downlink transmission simultaneously and the second time unit that allows the base station to perform uplink reception but does not allow the base station to perform downlink transmission, so that the terminal device does not need to perform uplink working BWP switching when switching between the first time unit and the second time unit, avoiding the interruption time caused by the working BWP switching, thereby saving communication resources.
[0095] In an exemplary embodiment, Figure 2 the resource determination method for uplink transmission provided may further include: in the first time unit, performing uplink transmission using the uplink channel and / or signal configuration corresponding to the first initial uplink BWP or the first active uplink BWP; and / or, in the second time unit, performing uplink transmission using the uplink channel and / or signal configuration corresponding to the second initial uplink BWP or the second active uplink BWP.
[0096] In the embodiments of the present disclosure, the above step of performing uplink transmission in the first time unit (i.e., in the first time unit, performing uplink transmission using the uplink channel and / or signal configuration corresponding to the first initial uplink BWP or the first active uplink BWP) can be executed alone; or, the above step of performing uplink transmission in the second time unit (i.e., in the second time unit, performing uplink transmission using the uplink channel and / or signal configuration corresponding to the second initial uplink BWP or the second active uplink BWP) can be executed alone; or, the above step of performing uplink transmission in the first time unit and the above step of performing uplink transmission in the second time unit can be executed.
[0097] It should be noted that the present disclosure does not limit the execution order of the above step of performing uplink transmission in the first time unit and the above step of performing uplink transmission in the second time unit, that is, uplink transmission can be performed in the first time unit first and then in the second time unit, or uplink transmission can be performed in the second time unit first and then in the first time unit, or uplink transmission can be performed in the first time unit and in the second time unit simultaneously.
[0098] In an embodiment of the present disclosure, in a time slot in which a base station can simultaneously perform uplink reception and downlink transmission, the uplink channel and / or signal configuration corresponding to the initial uplink BWP or the active uplink BWP for the time slot can be used for uplink transmission.
[0099] In an embodiment of the present disclosure, in a time slot in which a base station only performs uplink reception, the uplink channel and / or signal configuration corresponding to the initial uplink BWP or the active uplink BWP for the time slot can be used for uplink transmission.
[0100] Among them, the above uplink channels may include at least one of PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), and PRACH (Physical Random Access Channel), and the above uplink signals may include SRS (Sounding Reference Signal).
[0101] In an exemplary embodiment, the above method may further include: indicating, by a domain of frequency-domain resource allocation in a first DCI, the resource blocks allocated in a first initial uplink BWP or a first active uplink BWP for a first time unit; indicating, by a domain of frequency-domain resource allocation in the first DCI or a domain of frequency-domain resource allocation in a second DCI, the resource blocks allocated in a second initial uplink BWP or a second active uplink BWP for a second time unit, where the first DCI and the second DCI are transmitted separately.
[0102] In an embodiment of the present disclosure, the domain of frequency-domain resource allocation in DCI can simultaneously allocate the resource blocks in the corresponding initial uplink BWP or active uplink BWP for both the time slots in which the base station can simultaneously perform uplink reception and downlink transmission and the time slots in which the base station only performs uplink reception. This situation can be applied, for example, to the time slots of uplink transmission scheduled by DCI including multiple time slots, that is, the time slots of uplink transmission scheduled by DCI include both the time slots in which the base station can simultaneously perform uplink reception and downlink transmission and the time slots in which the base station only performs uplink reception.
[0103] Alternatively, in the embodiments of the present disclosure, the domain of the frequency-domain resource allocation in a DCI (such as the first DCI) corresponds to the resource blocks in the initial uplink BWP or the active uplink BWP corresponding to the time slot allocation that allows the base station to perform uplink reception and downlink transmission simultaneously, and the domain of the frequency-domain resource allocation in another DCI (such as the second DCI) corresponds to the resource blocks in the initial uplink BWP or the active uplink BWP corresponding to the time slot allocation for the base station to only perform uplink reception. The domains of the frequency-domain resource allocation corresponding to the resource blocks in the initial uplink BWP or the active uplink BWP for different types of time slot allocations are included in multiple DCIs that are not transmitted simultaneously. In an exemplary embodiment, the DCI (such as the first DCI and the second DCI) further includes differentiation information for the frequency-domain resource allocation, and the differentiation information for the frequency-domain resource allocation is used to distinguish whether the domain of the frequency-domain resource allocation in the DCI indicates the resource blocks allocated in the first initial uplink BWP or the first active uplink BWP for the first time unit, or indicates the resource blocks allocated in the second initial uplink BWP or the second active uplink BWP for the second time unit. That is, the differentiation information for the frequency-domain resource allocation indicates the type of time unit to which the uplink BWP where the resource blocks allocated by the domain of the frequency-domain resource allocation in the DCI belong.
[0104] The resource determination method for uplink transmission provided by the embodiments of the present disclosure can configure resources with a relatively narrow frequency-domain width for uplink transmission in the first time unit when the base station can perform uplink reception and downlink transmission simultaneously. The frequency resources are located at the center of the frequency band, and both sides of the frequency band can be regarded as guard bands, which is beneficial to reducing the adjacent-frequency interference between operators; in the second time unit when the base station only performs uplink reception, resources with a relatively wide frequency-domain width can be configured for uplink transmission, which is beneficial to improving the uplink rate or reliability; the frequency resources for uplink transmission in the second time unit when the base station only performs uplink reception can be located at any position in the frequency band, which is beneficial to the base station to flexibly schedule the frequency-domain position of uplink transmission, realize continuous uplink resource allocation, and reduce the fragmentation of uplink frequency-domain resources.

[0119] For the specific description of the above method embodiment executed by the terminal device, reference may be made to the above method embodiment executed by the base station, and details are not described herein again in the present disclosure.
[0120] Figure 5 It is a flowchart of a method for determining resources for uplink transmission according to an exemplary embodiment. The method provided by the embodiments of the present disclosure may be executed by a base station, but the present disclosure is not limited thereto.
[0121] As Figure 5 shown, the method for determining resources for uplink transmission provided by the embodiments of the present disclosure may include the following steps.
[0122] In step S502, determine the frequency resources for uplink transmission in the first time unit, determine the frequency resources for uplink transmission in the second time unit, and determine at least one of the frequency offset and the frequency repetition times.
[0123] Among them, the frequency offset is used to represent the frequency offset between the frequency resources occupied by uplink transmission in the first time unit and the frequency resources occupied by uplink transmission in the second time unit, and the frequency repetition times is used to represent the multiple of the size of the frequency resources occupied by uplink transmission in the second time unit relative to the size of the frequency resources occupied by uplink transmission in the first time unit; the first time unit is a time unit that allows the base station to simultaneously perform uplink reception and downlink transmission, and the second time unit is an uplink time unit.
[0124] In the embodiments of the present disclosure, the first time unit being a time unit that allows the base station to simultaneously perform uplink reception and downlink transmission means that the first time unit is a time unit in which the base station can simultaneously perform uplink reception and downlink transmission. In an actual communication process, in the first time unit, the base station can simultaneously perform uplink reception and downlink transmission, the base station can also perform uplink reception alone, or the base station can also perform downlink transmission alone. The first time unit is the full-duplex time unit.
[0125] In an embodiment of the present disclosure, the second time unit is an uplink time unit, which means that the second time unit is a time unit that allows the base station to perform uplink reception and does not allow the base station to perform downlink transmission. In the actual communication process, during the second time unit, the base station only performs uplink reception and does not perform downlink transmission. The time unit in which the base station described in the embodiment of the present disclosure only performs uplink reception refers to a time unit that allows the base station to perform uplink reception and does not allow the base station to perform downlink transmission when the base station communicates with the terminal device, that is, the uplink time unit.
[0126] In an embodiment of the present disclosure, the first time unit may include a first time slot and / or a first symbol, and the second time unit may include a second time slot and / or a second symbol.
[0127] In an embodiment of the present disclosure, the base station may determine the frequency resources for uplink transmission in the first time unit, determine the frequency resources for uplink transmission in the second time unit, and determine at least one of the frequency offset and the frequency repetition count.
[0128] In an exemplary embodiment, the frequency offset is a subcarrier offset, a resource block offset, or a resource block group offset.
[0129] That is, the frequency offset may be the subcarrier offset between the subcarriers occupied by the uplink transmission in the first time unit and the subcarriers occupied by the uplink transmission in the second time unit, or the frequency offset may be the resource block offset between the resource blocks occupied by the uplink transmission in the first time unit and the resource blocks occupied by the uplink transmission in the second time unit, or the frequency offset may be the resource block group offset between the resource block groups occupied by the uplink transmission in the first time unit and the resource block groups occupied by the uplink transmission in the second time unit.
[0130] In an exemplary embodiment, the frequency offset is the offset between the lowest frequency position of the frequency resources occupied by the uplink transmission in the first time unit and the lowest frequency position of the frequency resources occupied by the uplink transmission in the second time unit, or the frequency offset is the offset between the highest frequency position of the frequency resources occupied by the uplink transmission in the first time unit and the highest frequency position of the frequency resources occupied by the uplink transmission in the second time unit.
[0131] That is, the frequency offset may be a subcarrier offset between the subcarrier with the lowest frequency occupied by the uplink transmission in the first time unit and the subcarrier with the lowest frequency occupied by the uplink transmission in the second time unit, or the frequency offset may be a resource block offset between the resource block with the lowest frequency occupied by the uplink transmission in the first time unit and the resource block with the lowest frequency occupied by the uplink transmission in the second time unit, or the frequency offset may be a resource block group offset between the resource block group with the lowest frequency occupied by the uplink transmission in the first time unit and the resource block group with the lowest frequency occupied by the uplink transmission in the second time unit, or the frequency offset may be a subcarrier offset between the subcarrier with the highest frequency occupied by the uplink transmission in the first time unit and the subcarrier with the highest frequency occupied by the uplink transmission in the second time unit, or the frequency offset may be a resource block offset between the resource block with the highest frequency occupied by the uplink transmission in the first time unit and the resource block with the highest frequency occupied by the uplink transmission in the second time unit, or the frequency offset may be a resource block group offset between the resource block group with the highest frequency occupied by the uplink transmission in the first time unit and the resource block group with the highest frequency occupied by the uplink transmission in the second time unit.
[0132] In an exemplary embodiment, the frequency offset is used to represent the offset of the frequency resource occupied by the uplink transmission in the first time unit relative to the frequency resource occupied by the uplink transmission in the second time unit, or the frequency offset is used to represent the offset of the frequency resource occupied by the uplink transmission in the second time unit relative to the frequency resource occupied by the uplink transmission in the first time unit.
[0133] In an exemplary embodiment, the frequency repetition times are a subcarrier multiple, a resource block multiple, or a resource block group multiple.
[0134] That is, the frequency repetition times are the multiple of the subcarriers occupied by the uplink transmission in the second time unit relative to the subcarriers occupied by the uplink transmission in the first time unit, or the frequency repetition times are the multiple of the resource blocks occupied by the uplink transmission in the second time unit relative to the resource blocks occupied by the uplink transmission in the first time unit, or the frequency repetition times are the multiple of the resource block groups occupied by the uplink transmission in the second time unit relative to the resource block groups occupied by the uplink transmission in the first time unit.
[0135] In step S504, at least one of the frequency offset and the frequency repetition times is configured for the terminal device.
[0136] In the embodiments of the present disclosure, the base station may configure at least one of the frequency offset and the frequency repetition times for the terminal device through at least one of RRC signaling, MAC CE, and DCI.
[0137] In the embodiments of the present disclosure, the above method may further include: configuring an initial uplink BWP and / or activating an uplink BWP; performing uplink transmission using the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP. In the embodiments of the present disclosure, the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP include the frequency resources for uplink transmission, and the frequency resources for uplink transmission configured using the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP are used for uplink transmission in a first time unit or a second time unit. In the embodiments of the present disclosure, the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP further include other configuration information other than the frequency resources for uplink transmission, and the other configuration information other than the frequency resources for uplink transmission configured using the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP is used for uplink transmission in the first time unit and the second time unit.
[0138] In the embodiments of the present disclosure, for uplink transmission on one carrier, an initial uplink BWP is configured, and / or, an activated uplink BWP is configured, and uplink transmission is performed using the uplink channels and / or signal configurations corresponding to the initial uplink BWP or the activated uplink BWP.
[0139] Wherein, the above uplink channels may include at least one of PUSCH, PUCCH, and PRACH, and the above uplink signals may include SRS.
[0140] In the embodiments of the present disclosure, performing uplink transmission on different types of time units includes transmitting the same uplink information or different uplink information, or transmitting the same uplink signal on the same physical uplink channel. The uplink transmission performed on different types of time units may be scheduled by the same DCI, that is, the time units applied to the uplink transmission scheduled by the DCI include multiple types of time units, including both the time units when the base station can simultaneously perform uplink reception and downlink transmission and the time units when the base station only performs uplink reception; or, the uplink transmission performed on different types of time units may be scheduled by different DCIs.
[0141] The resource determination method for uplink transmission provided by the embodiments of the present disclosure can utilize the frequency offset and / or relative frequency repetition times between the frequency resources for uplink transmission by configuring different types of time units (i.e., the first time unit that allows the base station to simultaneously perform uplink reception and downlink transmission, and the second time unit that allows the base station to perform uplink reception but does not allow the base station to perform downlink transmission), so as to fully utilize the bandwidth available for uplink transmission in different types of time units for uplink transmission. Moreover, this method can be applied to the situation where the bandwidths available for uplink transmission in different types of time units are different. In the first time unit where the base station can simultaneously perform uplink reception and downlink transmission, resources with a relatively narrow frequency domain width can be configured for uplink transmission, and the frequency resources are located at the center of the frequency band, and the two sides of the frequency band can be regarded as guard bands, which is beneficial to reducing adjacent frequency interference between operators; in the second time unit where the base station only performs uplink reception, resources with a relatively wide frequency domain width can be configured for uplink transmission, which is beneficial to improving the uplink rate or reliability; the frequency resources for uplink transmission in the second time unit where the base station only performs uplink reception can be located at any position in the frequency band, which is beneficial for the base station to flexibly schedule the frequency domain position of uplink transmission, realize continuous uplink resource allocation, and reduce the fragmentation of uplink frequency domain resources.
[0142] Figure 6 It is a flowchart of a resource determination method for uplink transmission shown according to an exemplary embodiment. The method provided by the embodiments of the present disclosure can be executed by a terminal device, but the present disclosure is not limited thereto.
[0143] As Figure 6 shown, the resource determination method for uplink transmission provided by the embodiments of the present disclosure may include the following steps.
[0144] In step S602, receive at least one of the frequency offset and frequency repetition times configured by the base station.
[0145] Among them, the frequency offset is used to represent the frequency offset between the frequency resources occupied for uplink transmission in the first time unit and the frequency resources occupied for uplink transmission in the second time unit, and the frequency repetition times is used to represent the multiple of the size of the frequency resources occupied for uplink transmission in the second time unit relative to the size of the frequency resources occupied for uplink transmission in the first time unit; the first time unit is a time unit that allows the base station to simultaneously perform uplink reception and downlink transmission, and the second time unit is an uplink time unit.
[0146] In the embodiments of the present disclosure, the terminal device may receive at least one of the frequency offset and frequency repetition times configured by the base station.
[0147] In an exemplary embodiment, the frequency offset is a subcarrier offset, a resource block offset, or a resource block group offset.
[0148] In an exemplary embodiment, the frequency offset is the offset between the lowest frequency position of the frequency resources occupied for uplink transmission in the first time unit and the lowest frequency position of the frequency resources occupied for uplink transmission in the second time unit, or the frequency offset is the offset between the highest frequency position of the frequency resources occupied for uplink transmission in the first time unit and the highest frequency position of the frequency resources occupied for uplink transmission in the second time unit.
[0149] In an exemplary embodiment, the frequency offset is used to represent the offset of the frequency resources occupied for uplink transmission in the first time unit relative to the frequency resources occupied for uplink transmission in the second time unit, or the frequency offset is used to represent the offset of the frequency resources occupied for uplink transmission in the second time unit relative to the frequency resources occupied for uplink transmission in the first time unit.
[0150] In an exemplary embodiment, the frequency repetition count is a subcarrier multiple, a resource block multiple, or a resource block group multiple.
[0151] In step S604, determine the frequency resources for uplink transmission in the first time unit or the frequency resources for uplink transmission in the second time unit.
[0152] In the embodiments of the present disclosure, the base station may configure the frequency resources for uplink transmission in the first time unit or the frequency resources for uplink transmission in the second time unit for the terminal device; that is, the terminal device may obtain the frequency resources for uplink transmission in the first time unit or the frequency resources for uplink transmission in the second time unit from the configuration information sent by the base station. For example, the terminal device may obtain the frequency resources for uplink transmission from the uplink channel and / or signal configuration information corresponding to the initial uplink BWP or the activated uplink BWP sent by the base station, and use the frequency resources for uplink transmission to perform uplink transmission in the first time unit or the second time unit. For another example, the terminal device may obtain the frequency resources for uplink transmission from the DCI sent by the base station, and use the frequency resources for uplink transmission to perform uplink transmission in the first time unit or the second time unit.
