Description

Resource determination method, device, equipment and storage medium for uplink transmission

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a method and device for determining resources for uplink transmission, an electronic device, and a storage medium.

Background

Conventional duplex modes include time division duplex (Time Division Duplexing, TDD) and frequency division duplex (Frequency Division Duplexing, FDD). In order to adapt to uplink and downlink time-varying and asymmetric service requirements, a current fifth Generation mobile communication technology (5 th Generation mobile networks, 5th Generation wireless systems or 5th-Generation, 5G) New air interface (NR) system supports dynamic TDD to allow a base station to dynamically adjust the uplink and downlink time slot ratio, and a future duplex mode will evolve towards a full duplex direction.

In a related-art implementation manner of full duplex of sub-bands, in order to mitigate adjacent channel interference between operators, in a downlink time slot of a traditional TDD, uplink transmission can only be located in a central position of a frequency band in a frequency domain. Thus, in different types of time slots, such as time slots in which the base station can simultaneously perform uplink reception and downlink transmission, and time slots in which only uplink reception is performed, bandwidths available for uplink transmission are different.

However, for uplink transmission on one carrier, the bandwidths available for uplink transmission in different timeslots are the same in the NR system in the related art, and the determination of the uplink transmission frequency resource is not differentiated for different timeslots, so that the uplink transmission method in the related art is not suitable for the case where the bandwidths available for uplink transmission in different timeslots are different.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many 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 described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely 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 a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor terminals and/or microcontroller terminals.

Full duplex communication can simultaneously transmit uplink information and downlink information on the same frequency band. Whether frequency resources adopted for simultaneous transmission of uplink information and downlink information in the same frequency band overlap or not can be divided into the following implementation modes, referring to fig. 1: 1. the uplink and downlink information adopts full duplex of non-overlapping frequency resources, as shown in a figure (a), and uplink transmission is carried out at the frequency domain center of a TDD downlink time slot, which is also called sub-band non-overlapping full duplex; 2. the uplink and downlink information adopts full duplex of overlapped frequency resources, as shown in the figure (b), uplink and downlink are simultaneously transmitted in the frequency domain center of a TDD downlink time slot, which is also called sub-band overlapped full duplex, and the figure (c) simultaneously transmits uplink and downlink in any frequency domain position, which is also called full overlapped full duplex.

In the above-mentioned different implementation manners of full duplex, the manner of fig. 1 (a) performs uplink transmission in the frequency domain center of the TDD downlink timeslot, which has the following advantages, so that the following may be preferentially implemented: the uplink coverage can be improved, the uplink capacity can be increased, and the uplink transmission delay can be reduced; the uplink and the downlink adopt different frequency resources, which is beneficial to the elimination of self-interference of the base station; the transmission in opposite directions is placed in the center of the frequency band, and the two sides of the frequency band can be equivalent to a protection band, which is beneficial to reducing adjacent frequency interference among operators; if the adjacent cells adopt the same uplink and downlink resource division pattern, the cross link interference can be reduced.

In the embodiment of the disclosure, full duplex may be preferentially implemented at the base station side, and the UE (User Equipment, also called terminal Equipment) side may still maintain the conventional duplex mode. The present disclosure is not limited thereto. That is, the present disclosure does not limit whether the UE performs uplink and downlink transmission simultaneously in one time unit or only performs uplink or downlink transmission. I.e. the present disclosure is applicable to UE supporting or not supporting uplink and downlink simultaneous transmission.

The resource determining method for uplink transmission provided in the embodiment of the present disclosure may be applied to various full duplex implementations shown in fig. 1, and in the following illustration, the full duplex implementation of fig. 1 (a) is taken as an example, but the present disclosure is not limited thereto. That is, the present disclosure does not limit whether uplink and downlink transmissions overlap in frequency in a time unit in which a base station can simultaneously perform uplink reception and downlink transmission. That is, the present disclosure is applicable to frequency resources of uplink transmission and downlink transmission in the band center of a downlink slot of a conventional TDD without overlapping, and is also applicable to frequency resources of uplink transmission and downlink transmission in the band center of a downlink slot of a conventional TDD.

Hereinafter, each step of the resource determining method for uplink transmission in the exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

Fig. 2 is a flow chart illustrating a method of resource determination for uplink transmission according to an example embodiment. The method provided by the embodiments of the present disclosure may be performed by a base station, but the present disclosure is not limited thereto.

As shown in fig. 2, the method for determining resources for uplink transmission provided by the embodiment of the present disclosure may include the following steps.

In step S202, a first uplink BWP (Bandwidth Part) for a first time unit and a second uplink BWP (Bandwidth Part) for a second time unit are configured, where 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.

In the embodiment of the disclosure, the first time unit is a time unit that allows the base station to perform uplink reception and downlink transmission at the same time, which means that the first time unit is a time unit that the base station can perform uplink reception and downlink transmission at the same time. In the actual communication process, in the first time unit, the base station may perform uplink reception and downlink transmission at the same time, or the base station may perform uplink reception alone, or the base station may perform downlink transmission alone. The first time unit is a full duplex time unit.

In the embodiment of the present disclosure, the second time unit is an uplink time unit, which refers to a time unit in which the base station is allowed to perform uplink reception and the base station is not allowed 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 only performs uplink reception in the embodiment of the present disclosure refers to a time unit in which the base station is allowed to perform uplink reception and is not allowed to perform downlink transmission when the base station communicates with the terminal device, that is, an uplink time unit.

In an embodiment of the disclosure, the first time unit may include a first slot and/or a first symbol, and the second time unit may include a second slot and/or a second symbol. In the following examples, the first time unit is taken as a first time slot and the second time unit is taken as a second time slot, but the disclosure is not limited thereto.

For uplink transmission of a conventional NR system on one carrier, bandwidths available for uplink transmission in different timeslots are the same, and determination of uplink transmission frequency resources is not differentiated for different types of timeslots:

In the case that no BWP switch occurs in one carrier, only uplink transmission of different timeslots can be performed based on the uplink channel and signal configuration corresponding to the unique uplink operation BWP. The DCI (Downlink Control Information) may indicate only one BWP, and the domain of the DCI in which the frequency domain resources are allocated may indicate only the frequency domain resources in one BWP.

If uplink BWP switching is performed when the base station can perform uplink reception and downlink transmission simultaneously and perform only uplink reception when switching between uplink reception slots, the operation BWP switching is more frequent, and the UE operation BWP switching interruption delay causes resource waste.

Therefore, the uplink transmission method in the related art is not suitable for the situation that different types of timeslots are available for uplink transmission with different bandwidths.

In the embodiment of the disclosure, the base station may configure the terminal device with a first uplink BWP for a time slot in which the base station may simultaneously perform uplink reception and downlink transmission, and the base station may configure the terminal device with a second uplink BWP for a time slot in which the base station only performs uplink reception, so as to determine uplink transmission frequency resources by configuring different uplink BWP. The first upstream BWP and the second upstream BWP may have different frequency positions and/or sizes, so that the upstream transmission may be performed by fully using the bandwidths available for the upstream transmission in different types of slots. The method can be applied to the situation that the bandwidths of the time slots which can be used for uplink transmission and the time slots which can be used for only uplink reception are different in the time slots which can be used for uplink reception and downlink transmission at the base station.

Referring to fig. 3, in the embodiment of the present disclosure, for uplink transmission in one carrier, a base station may configure one set of uplink BWP for a first slot and a second slot, respectively, i.e., one set of uplink BWP for the first slot and another set of uplink BWP for the second slot, and each set of uplink BWP may include at least one of initial BWP, BWP set, first activated BWP, and BWP to be activated. Both the first activated BWP and the BWP to be activated may be the activated BWP.

In an exemplary embodiment, the first uplink BWP may be a first initial uplink BWP and/or a first active uplink BWP, and the second uplink BWP may be a second initial uplink BWP and/or a second active uplink BWP.

In the embodiment of the present disclosure, the base station may configure the initial uplink BWP and the active uplink BWP respectively, and the base station may also configure the initial uplink BWP and the active uplink BWP simultaneously.

Wherein, the initial uplink BWP and the active uplink BWP can both be used as uplink operation BWP. After the UE enters the RRC (Radio Resource Control ) connected state, the base station may activate uplink BWP through RRC signaling, DCI, or MAC (Medium Access Control ) CE (Control Element) configuration. The initial uplink BWP may be used as the uplink working BWP before the UE enters the connected state, e.g. in idle state, during random access, when the UE has not yet obtained the configuration to activate the uplink BWP.

In an exemplary embodiment, configuring a first upstream BWP for a first time unit and a second upstream BWP for a second time unit includes: a first initial upstream BWP for a first time unit and a second initial upstream BWP for a second time unit are configured.

In the embodiment of the disclosure, the base station may configure, via broadcast information, the first initial uplink BWP to the terminal device for a time slot in which the base station may simultaneously perform uplink reception and downlink transmission, and the base station may configure, via broadcast information, the second initial uplink BWP to the terminal device for a time slot in which the base station may only perform uplink reception.

In an exemplary embodiment, configuring a first upstream BWP for a first time unit and a second upstream BWP for a second time unit includes: a first active upstream BWP for a first time unit and a second active upstream BWP for a second time unit are configured.

In the embodiment of the disclosure, for uplink transmission on one carrier, there may be 2 uplink BWP activated at the same time, that is, there may be 2 working uplink BWP of the UE, which are respectively used for timeslots in which the base station may simultaneously perform uplink reception and downlink transmission, and timeslots in which only uplink reception is performed.

In an exemplary embodiment, the configuration of the first active upstream BWP may be the configuration of the first active upstream BWP and/or the configuration of the first to-be-activated upstream BWP, and the configuration of the second active upstream BWP may be the configuration of the second first active upstream BWP and/or the configuration of the second to-be-activated upstream BWP.

In an exemplary embodiment, configuring a first active upstream BWP for a first time unit and a second active upstream BWP for a second time unit includes: a first activated upstream BWP for a first time unit and a second first activated upstream BWP for a second time unit are configured.

In the embodiment of the present disclosure, the base station may configure a first activated uplink BWP for the first time slot, and use the first activated uplink BWP as the first activated uplink BWP; the base station may configure a second first activated uplink BWP for the second time slot, and use the second first activated uplink BWP as the second activated uplink BWP. For example, the base station may configure the terminal device with the first activated upstream BWP and the second activated upstream BWP through RRC signaling.

In an exemplary embodiment, configuring a first active upstream BWP for a first time unit and a second active upstream BWP for a second time unit includes: indicating the first uplink BWP to be activated, so as to switch the first uplink BWP to be activated into the indicated first uplink BWP to be activated; and indicating the second uplink BWP to be activated so as to switch the second uplink BWP to the indicated second uplink BWP to be activated.

In the embodiment of the present disclosure, the base station may indicate, through at least one of RRC signaling, MAC CE, DCI, that one BWP to be activated is used for a time slot in which the base station may perform uplink reception and downlink transmission at the same time. The base station may instruct another BWP to be activated for a slot in which the base station receives only uplink through at least one of RRC signaling, MAC CE, DCI.

Wherein the BWP to be activated is used to activate the handoff of the BWP. The BWP currently activated for a different type of slot will be changed to the BWP to be activated for the corresponding slot indicated by at least one of RRC signaling, MAC CE, DCI, respectively.

In an exemplary embodiment, indicating the first uplink BWP to be activated includes: indicating a first uplink BWP to be activated by a domain for indicating BWP in the first DCI; indicating a second uplink BWP to be activated includes: indicating a second uplink BWP to be activated by a domain for indicating BWP in the first DCI or a domain for indicating BWP in the second DCI; wherein the first DCI and the second DCI are transmitted separately.

In the embodiment of the present disclosure, the domain for indicating BWP in DCI is used to indicate one uplink BWP to be activated for a time slot where the base station can simultaneously perform uplink reception and downlink transmission, and to indicate one uplink BWP to be activated for a time slot where the base station only performs uplink reception.

In the embodiment of the present disclosure, the domain for indicating BWP in DCI may indicate that 2 uplink BWP to be activated are applied to different types of timeslots respectively at the same time.

Alternatively, in the embodiment of the present disclosure, the domain for indicating BWP in one DCI indicates one uplink BWP to be activated for a time slot in which the base station may perform uplink reception and downlink transmission at the same time; the field in the other DCI for indicating BWP indicates that another uplink BWP to be activated is used for a slot where the base station performs only uplink reception. Wherein, the DCI indicating the uplink BWP to be activated for different types of slots is a plurality of DCIs not transmitted simultaneously. In an exemplary embodiment, the DCI (e.g., the first DCI and the second DCI) further includes distinguishing information of BWP application time units, where the distinguishing information of the BWP application time units is used to distinguish whether the uplink BWP to be activated, indicated by the domain of BWP, in the DCI is a time unit used for the base station to perform uplink reception and downlink transmission simultaneously, or a time unit used for the base station to perform only uplink reception, that is, the distinguishing information of the BWP application time units indicates a time unit type of the uplink BWP to be activated, indicated by the domain of BWP, in the DCI.

In the embodiment of the present disclosure, the base station may configure the uplink BWP set 1 and the uplink BWP set 2 through RRC signaling, where the uplink BWP set 1 may be used for a time slot in which the base station may perform uplink reception and downlink transmission at the same time, and the uplink BWP set 2 may be used for a time slot in which the base station may perform only uplink reception. One or more upstream BWP may be configured in each set. In an exemplary embodiment, the first set of upstream BWP does not include the first initial upstream BWP and the second set of upstream BWP does not include the second initial upstream BWP.
