Description

Resource allocation method and system for uplink and downlink frequency domain non-overlapping full duplex communication

Technical Field

The disclosure relates to the technical field of communication, and in particular relates to a resource allocation method and system for uplink and downlink frequency domain non-overlapping full duplex communication.

Background

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

In order to further improve the use efficiency of wireless resources and improve the throughput and capacity of the system, a future duplex mode will evolve towards a full duplex direction. Full duplex communication can simultaneously transmit uplink and downlink information on the same carrier. In different implementations of full duplex, non-overlapping full duplex in the uplink and downlink frequency domains is more advantageous for interference cancellation and will be preferentially subjected to standardization research. The uplink and downlink frequency domain non-overlapping full duplex includes different situations, as shown in fig. 1A, uplink transmission is performed in the frequency domain center of the conventional TDD downlink time slot; as shown in fig. 1B, uplink transmission is performed in the frequency domain center of the conventional TDD downlink slot, and downlink transmission is performed in the frequency domain center of the uplink slot.

In the existing NR system, the carrier Bandwidth may be relatively large, and in consideration of power saving factors of a UE (User Equipment), BWP (Bandwidth Part) is introduced, and a terminal uses this as an operating Bandwidth. BWP is a number of CRBs (Common Resource Block, common resource blocks) that are contiguous in the frequency domain within one carrier.

Disclosure of Invention

The inventors found that: in uplink and downlink frequency domain non-overlapping full duplex communication, there is a case that a frequency domain resource for one-direction (uplink or downlink) transmission is divided into two discontinuous parts, but the configuration of BWP in the current NR system is not suitable for the uplink and downlink frequency domain non-overlapping full duplex communication scenario. For example, if the frequency domain resources occupied by the configured downlink BWP are contiguous and the bandwidth is wide, the allocated downlink frequency domain resources may collide with the uplink frequency domain resources; if the configured frequency domain position of the downlink BWP is located at one side of the carrier bandwidth and is not overlapped with the frequency domain resource used for uplink transmission in the time slot where the downlink transmission is located, it is unfavorable to fully utilize the discontinuous two-part frequency domain resource available for downlink transmission to improve the downlink transmission rate and performance.

One technical problem to be solved by the present disclosure is: when the NR system is used for the non-overlapping full duplex communication of the uplink and downlink frequency domains, how to enable the BWP configuration to be suitable for the non-overlapping full duplex communication scene of the uplink and downlink frequency domains, discontinuous frequency domain resources are fully utilized for transmission, and the transmission rate is improved.

Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

The present disclosure provides a resource allocation method for uplink and downlink frequency domain non-overlapping full duplex communication, which is not only suitable for a base station to use uplink and downlink frequency domain non-overlapping full duplex, but also for a terminal to keep a traditional duplex mode; the method is also suitable for the base station and the terminal to adopt the non-overlapping full duplex of the uplink and downlink frequency domains. That is, the terminal performs uplink and downlink transmission at the same time, or only uplink or downlink transmission at one time is not limited. The method is applicable to the terminal supporting or not supporting uplink and downlink simultaneous transmission.

In the present disclosure, a terminal communicates with a base station in a first direction, for example, uplink, and the terminal transmits uplink information to the base station, the base station receives the uplink information transmitted by the terminal, and the terminal receives downlink information transmitted by the base station, and the base station transmits downlink information to the terminal. The second direction is opposite to the first direction. The first direction is, for example, upstream, and the second direction is downstream. The first direction is, for example, downstream, and the second direction is upstream.

For example, when the first direction is downlink, as shown in fig. 1A, the uplink and downlink frequency domain non-overlapping full duplex communication is performed, where the frequency domain resource of downlink transmission is divided into two discontinuous parts, and the existing NR system cannot be well applied to a scenario that the frequency domain resource available for downlink transmission in a carrier includes two discontinuous parts. The existing NR system downlink resource configurations such as PDCCH (Physical Downlink Control Channel ) CORESET, PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) except CORESET (Control Resource Set ) 0, NZP CSI-RS (Non-Zero Power Channel-State Information Reference Signal, non-zero power channel state information reference signal) are all within BWP, which consists of CRBs that are contiguous in the frequency domain. If the configured frequency domain position of the downlink BWP is located at one side of the carrier bandwidth and is not overlapped with the frequency domain resource used for uplink transmission in the time slot where the downlink transmission is located, it is unfavorable to fully utilize the discontinuous two-part frequency domain resource available for downlink transmission to improve the downlink transmission rate and performance. If the configured frequency domain position of the downlink BWP overlaps with the frequency domain resource used for uplink transmission in the time slot where the downlink transmission is located, the allocated downlink frequency domain resource may collide with the uplink frequency domain resource. PDSCH type 1 resource allocation can only allocate consecutive virtual resource blocks, SIB (System Information Block ), paging (Paging) message, RAR (Random Access Response ), TC-RNTI (Temporary Cell-Radio Network Temporary Identifier), scrambled PDSCH, etc. only support type 1 resource allocation. In order to fully utilize the downlink two-part frequency domain resource, the frequency domain resource allocated by the type 1 resource allocation may collide with the frequency domain resource for uplink transmission in the time slot where the downlink transmission is located. Although the existing NR system supports configuring physical resource blocks through a RateMatchPattern (rate matching pattern) information element among RRC (Radio Resource Control) information elements such that PDSCH is not mapped to these configured physical resource blocks, a physical resource block that is unavailable for PDSCH configured by RateMatchPattern is not applicable to SIB, paging, RAR, TC-RNTI scrambled PDSCH, DMRS (Demodulation Reference Signal ) of PDSCH, and the like. The resource block where the NZP CSI-RS is located is determined by configuring the starting resource block and the number of resource blocks through RRC, so that in order to obtain CSI (Channel State Information ) with a wider bandwidth, the configured resources of the NZP CSI-RS may collide with the frequency domain resources used for uplink transmission in the time slot where downlink transmission is located.

The first direction is, for example, uplink, and downlink frequency domain non-overlapping full duplex, as shown in fig. 1B, in the uplink time slot of the conventional TDD, downlink transmission is located at the center of a carrier in the frequency domain, so that the frequency domain resource of the time slot available for uplink transmission in one carrier is divided into two discontinuous parts, and the existing NR system cannot be well applied to a scenario that the frequency domain resource available for uplink transmission in the carrier includes two discontinuous parts. The resource allocation of the existing NR system uplink, e.g., PUSCH (Physical Uplink Shared Channel ), is within BWP, which consists of CRBs that are contiguous in the frequency domain. If the configured frequency domain position of the uplink BWP is located at one side of the carrier bandwidth, it is not beneficial to fully utilize the discontinuous two-part frequency domain resources to improve the uplink transmission rate and performance. If the frequency domain location where the uplink BWP is configured overlaps with the frequency domain resource for downlink transmission in the frequency domain center in the time slot where the uplink transmission is located, the allocated uplink frequency domain resource may collide with the downlink frequency domain resource. The PUSCH type 1 resource allocation can only allocate continuous virtual resource blocks, so as to fully utilize the uplink two-part frequency domain resources, and the frequency domain resources allocated by the type 1 resource allocation may collide with the frequency domain resources used for downlink transmission in the frequency domain center.

In some embodiments, the first preset value, the second preset value, and the third preset value are configured by the terminal receiving the base station, or the first preset value, the second preset value, and the third preset value are predetermined, or some of the first preset value, the second preset value, and the third preset value are predetermined, and the rest of the preset values are configured by the terminal receiving the base station.

The communication unavailable CRB of the first direction includes a guard resource block and an uplink resource block.

In step S204, the base station transmits frequency domain resource allocation information to the terminal, and correspondingly, the terminal receives the frequency domain resource allocation information transmitted by the base station.

For example, the frequency domain resource configuration information is used to indicate resource blocks in the first set of CRBs and the second set of CRBs.

The frequency domain resource configuration information may indicate the allocated VRBs or allocated PRBs in a manner that the existing NR system allocates the VRBs or PRBs. In case the frequency domain resource configuration information indicates an allocated VRB, the allocated VRB is mapped to an allocated PRB in the manner of the existing NR system. The allocated PRBs correspond to part or all of the resource blocks in the first group of CRBs and the second group of CRBs, that is, the resource blocks indicated by the frequency domain resource allocation information. The frequency domain resource configuration information may be carried by DCI or by RRC information element.

In step S206, the terminal performs communication in the first direction with the base station on the resource block indicated by the frequency domain resource allocation information, and correspondingly, the base station performs communication in the first direction with the terminal on the resource block indicated by the frequency domain resource allocation information.

For example, when the first direction is uplink, the terminal transmits uplink information to the base station on the resource block indicated by the frequency domain resource allocation information, and when the first direction is downlink, the terminal receives downlink information transmitted by the base station on the resource block indicated by the frequency domain resource allocation information.

In the above embodiment, the terminal receives the BWP configuration information sent by the base station, and the configured BWP includes two sets of CRBs that are frequency-domain continuous for communication in the first direction, and further, the terminal performs communication in the first direction on the resource blocks in the first set of CRBs and the second set of CRBs according to the frequency-domain resource configuration information sent by the base station. The configuration of BWP in the present disclosure is different from the configuration that the conventional BWP only includes one set of continuous CRBs, and by the configuration of two sets of CRBs, in order to mitigate adjacent frequency interference in uplink and downlink frequency domain non-overlapping full duplex communication, in the case that the frequency domain resource for one-direction transmission is divided into two discontinuous parts, the two discontinuous frequency domain resources can be fully utilized, and collision of the frequency domain resource occupied by uplink and downlink transmission can be avoided, thereby improving the transmission rate.

Further embodiments of the resource allocation method for non-overlapping full duplex communication in the uplink and downlink frequency domain of the present disclosure are described below in conjunction with fig. 4. In the foregoing embodiment, the first set of CRBs and the second set of CRBs may be configured as frequency domain non-contiguous, and may be separated by resource blocks for communication in the second direction between the terminal and the base station, and the first set of CRBs and the second set of CRBs may be included in the same first BWP or in the second BWP and the third BWP, respectively. The BWP in the subsequent embodiment includes CRBs that are frequency domain continuous.

Fig. 4 is a flowchart of another embodiment of a resource allocation method for uplink and downlink frequency domain non-overlapping full duplex communication according to the present disclosure. As shown in fig. 4, the method of this embodiment includes: steps S402 to S406.

In step S402, the base station transmits BWP configuration information to the terminal, and accordingly, the terminal receives the BWP configuration information transmitted by the base station.

In some embodiments, the BWP of the BWP configuration information configuration comprises: the frequency domain continuous CRBs are used for communication in a first direction between the terminal and the base station.

In step S404, the base station transmits frequency domain resource allocation information to the terminal, and correspondingly, the terminal receives the frequency domain resource allocation information transmitted by the base station.

The frequency domain resource configuration information may be used to indicate resource blocks in the CRB.

The frequency domain resource configuration information may indicate the allocated VRBs or allocated PRBs in a manner that the existing NR system allocates the VRBs or PRBs. In case the frequency domain resource configuration information indicates an allocated VRB, the allocated VRB is mapped to an allocated PRB in the manner of the existing NR system. The allocated PRBs correspond to some or all of the resource blocks in the CRBs included in the BWP, that is, the resource blocks indicated by the frequency domain resource configuration information. The frequency domain resource configuration information may be carried by DCI or by RRC information element.

In step S406, if the resource block indicated by the frequency domain resource allocation information overlaps with the communication unavailable CRB in the first direction in the same time slot or symbol, the terminal does not perform communication in the first direction with the base station at the unavailable CRB, and accordingly, the base station does not perform communication in the first direction with the terminal at the unavailable CRB.

In some embodiments, in a case where the first direction is downlink, the communication in the first direction of the terminal includes: reception of one or more of DCI (Downlink Control Information ), PDSCH-carried information, CSI-RS (Channel-State Information Reference Signal, channel state information reference signal), DMRS (DeModulation Reference Signal ), PT-PS (Phase-Tracking Reference Signal, phase tracking reference signal), PRS (Positioning Reference Signal ); and/or, in the case that the first direction is uplink, the communication in the first direction of the terminal includes: and (3) transmitting one or more of information carried by the PUSCH, SRS (Sounding Reference Signal ), DMRS and PT-PS.

Further, in the case that the first direction is downlink, the DCI does not include DCI carried by PDCCH occupying control resources in CORESET0, and the information carried by PDSCH does not include SIB1. Therefore, DCI and SIB1 which occupy PDCCH bearing of control resources in CORESET0 are transmitted in preference to uplink information, and when the DCI and SIB1 conflict with the uplink information transmission frequency domain resources, the terminal and the base station still carry out communication in the first direction, namely the terminal receives DCI and SIB1 which occupy PDCCH bearing of control resources in CORESET0, so that the terminal can receive system information.

alternatively, the communication unavailable CRB of the first direction includes: the terminal receives a communication unavailable CRB in a first direction configured by a RateMatchPattern in a Radio Resource Control (RRC) information element configured by a base station.

Alternatively, in the case where the first direction is uplink, the communication unavailable CRB in the first direction includes, for example: one or more of SSB, CORESET 0 and SIB1, a first preset value of forward offset, a second preset value of backward offset, and a third preset value of high and low frequency offset. As shown in fig. 3C, the unavailable CRB for communication in the first direction is a symbol where the SSB is located, a first preset value number of symbols shifted forward, a second preset value number of symbols shifted backward, a resource block where the SSB is located, and a third preset value number of resource blocks shifted in the directions of high and low frequencies. Since SSB frequency domain locations are placed according to GSCN (Global Synchronization Channel Number ), there is a possibility of collision with frequency domain resources for uplink transmission. CORESET 0, SIB1 occupy contiguous resource blocks, and the frequency domain location may collide with the frequency domain resource for uplink transmission, especially at small bandwidths. At this time, the terminal does not communicate with the base station in the first direction at the unavailable CRB, i.e., the terminal does not transmit uplink at the unavailable CRB, thereby ensuring that other terminals can receive SSB and system information.

The first direction is opposite to the second direction, e.g., the first direction is upward, and the second direction is downward. CRBs for communication in the second direction include, for example: the BWP for communication in the second direction includes the CRB. The communication unavailable CRB of the first direction may be configured through RateMatchPattern. The signal or channel not available by the resource block configured by RateMatchPattern is extended to one or more of PDCCH, CSI-RS, DMRS, PT-RS, PRS, PUSCH, SRS, in addition to the existing PDSCH.

In some embodiments, if, in the case that the first direction is uplink, the frequency domain resource for uplink transmission by the terminal is not more than a third preset value frequency domain resource block from the frequency domain resource block in which one or more of SSB, CORESET 0 and SIB1 are located, within the range of the first preset value of symbols of one or more of SSB, CORESET 0 and SIB1 and the second preset value of symbols of forward offset, the communication unavailable CRB in the first direction includes: one or more of SSB, CORESET 0 and SIB1, and CRB within a range of a first predetermined value of symbols shifted forward and a second predetermined value of symbols shifted backward. At this time, the terminal does not perform uplink transmission in a range where the unavailable CRB and the base station do not perform transmission in the first direction, that is, the terminal performs uplink transmission in a range of one or more symbols of SSB, CORESET 0 and SIB1, a first preset value symbol shifted forward, and a second preset value symbol shifted backward.

The distance between the frequency domain resource for uplink transmission by the terminal and the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 are located is larger than a third preset value, which comprises the following two cases: 1) The frequency of the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 are located is higher than that of the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 are located, and the distance between the resource block with the lowest frequency in the frequency domain resource and the resource block with the highest frequency in the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 is located is larger than a third preset value; 2) The frequency of the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 is located is lower than that of the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 is located, and the distance between the resource block with the highest frequency in the frequency domain resource and the resource block with the lowest frequency in the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 is located in the uplink transmission frequency domain resource is larger than a third preset value. And the distance between the frequency domain resource for uplink transmission by the terminal and the frequency domain resource block where one or more of SSB, CORESET0 and SIB1 are located is not larger than a third preset value, and the two cases are not the two cases.

For example, the first preset value, the second preset value and the third preset value are configured by the terminal receiving base station, or the first preset value, the second preset value and the third preset value are pre-agreed, or part of the first preset value, the second preset value and the third preset value are pre-agreed, and the rest preset values are configured by the terminal receiving the base station. The base station may configure one or more of the first preset value, the second preset value, and the third preset value for the terminal through RRC common signaling or RRC dedicated signaling. One or more of the first preset value, the second preset value, and the third preset value may be 0. The first preset value and the second preset value may not be 0, so that when the time slot boundaries between different base stations are asynchronous, cross link interference caused by uplink transmission to one or more of PDCCH and SIB1 in SSB and CORESET0 can be reduced. The third preset value may not be 0, so that cross link interference caused by receiving one or more of PDCCH and SIB1 in SSB and CORESET0 by uplink transmission adjacent to the frequency domain can be reduced.

The terminal may not perform communication in the first direction with the base station at the unavailable CRB, and may discard information to be transmitted mapped on the communication unavailable CRB in the first direction. For one or more of PDCCH, PDSCH, PUSCH, not communicating may also be rate matching the information to be transmitted for resources other than CRBs for which communication in the first direction is not available.

In the above embodiment, one BWP configured includes CRBs that are frequency-domain continuous, and communication in the first direction is not performed on CRBs for which communication in the first direction is unavailable. Therefore, the frequency domain resources of the physical signals/channels can be configured in BWP, in order to reduce adjacent frequency interference among operators in uplink and downlink frequency domain non-overlapping full duplex communication, under the condition that the frequency domain resources for one-direction transmission in a carrier are divided into two discontinuous parts, the two discontinuous parts of the frequency domain resources in the carrier can be fully utilized, the conflict of uplink and downlink transmission is avoided, and the transmission rate is ensured.

In the above embodiment, the frequency domain resources configured by the RRC information element RateMatchPattern in the prior art and unavailable for communication in the first direction may be multiplexed, and the transmission of the unavailable resource application configured by the RateMatchPattern may be extended. Therefore, the configuration signaling design is simplified, the extended channel/signal can be transmitted with larger bandwidth, and the frequency domain discontinuous transmission resource is fully utilized. The traditional terminal can also not receive PDSCH in the unavailable frequency domain resource of downlink transmission, fully utilize the discontinuous downlink resource of the frequency domain, and ensure the downlink communication rate of the traditional terminal in the non-overlapping full duplex communication of the uplink and downlink frequency domains.

For one or more of PDCCH, SIB1 and SSB in CORESET 0, the first preset value and the second preset value corresponding to the time domain protection symbol are considered to be different from 0, so that when the time slot boundaries among different base stations are asynchronous, the cross link interference caused by uplink transmission to one or more of PDCCH and SIB1 in SSB and CORESET 0 can be reduced. And when the uplink transmission frequency domain resource is far away from one or more frequency domain resources (larger than a third preset value) in SSB, CORESET 0 and SIB1, especially in the case of large system bandwidth, the interference can be tolerated, and the uplink transmission can be carried out in the time slot/symbol of the interference, so that the opportunity of the uplink transmission is increased.
