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 proposes a resource allocation method, described below in connection with fig. 1.

Fig. 1 is a flow chart of some embodiments of the disclosed resource allocation method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S104.

In step S102, the base station sends a signaling carrying resource allocation configuration information to the terminal, and correspondingly, the terminal receives the signaling carrying resource allocation configuration information sent by the base station.

In some embodiments, the terminal receives signaling carrying resource allocation configuration information sent by the base station, where the resource allocation configuration information includes: the resource configuration information, the resource activation information and the positional offset relation configuration, or the resource allocation configuration information includes: resource activation information and positional offset relationship configuration. The resource configuration information includes: a first set comprising a plurality of configuration grant CG configurations, a second set comprising a plurality of semi-persistent scheduling, SPS, configurations, and a third set comprising one or more CG configurations and one or more SPS configurations, the resource activation information comprising: the first indication information is used for indicating that a plurality of CG configurations in the first set are activated simultaneously, the second indication information is used for indicating that a plurality of SPS configurations in the second set are activated simultaneously, and at least one item of third indication information is used for indicating that one or more CG configurations and one or more SPS configurations in the third set are activated simultaneously, the position offset relation configuration is used for indicating the position offset relation between CG transmissions corresponding to the plurality of CG configurations in the first set which are activated simultaneously, the position offset relation between SPS transmissions corresponding to the plurality of SPS configurations in the second set which are activated simultaneously, and at least one item of position offset relation between CG transmissions corresponding to the one or more CG configurations and SPS transmissions corresponding to the one or more SPS configurations in the third set which are activated simultaneously.

CG transmissions are, for example, CG PUSCH (Physical Uplink Shared Channel ), SPS transmissions are, for example, SPS PDSCH (Physical Downlink Shared Channel ).

In some embodiments, the signaling includes: RRC (Radio Resource Control ) signaling, MAC (Medium Access Control, medium access control signaling) and DCI (downlink control information).

The resource configuration information and the resource activation information are first described in detail below.

In some embodiments, the resource configuration information may be carried by RRC signaling or MAC signaling or DCI signaling; the resource activation information may be carried through RRC signaling or MAC signaling or DCI signaling. Further, in the case that the resource configuration information is carried through RRC signaling and/or MAC signaling, the resource activation information is carried through MAC signaling and/or DCI signaling.

For example, the resource configuration information includes several SPS/CG configurations that can be activated simultaneously to adapt to different XR traffic requirements, e.g., the resource configuration information includes CG configuration 1+cg configuration 2, or SPS configuration 1+sps configuration 2+sps configuration 3, or CG configuration 1+sps configuration 2.

For example, the following parameters may be configured for CG Tpye 2:

cs-RNTI: configuring a scheduling radio network temporary identity for activation/deactivation and retransmission

nrofHARQ-Processes: CG HARQ process number

harq-procad-Offset: offset value of CG HARQ process ID at NSA (non-independent networking)

harq-procad-Offset 2: offset value of CG HARQ process ID at SA (independent networking)

Perioconductivity: CG Type2 cycle

The following parameters may be configured for SPS:

nrofHARQ-Processes: SPS HARQ process number

harq-procad-Offset: offset value of SPS HARQ process ID

Perioconductivity: SPS period

In some embodiments, the resource configuration information further includes a first list including one or more first activation options, each first activation option including an identification of a plurality of CG configurations in the first set that are simultaneously activatable; and/or the resource configuration information further comprises a second list comprising one or more second activation options, each second activation option comprising an identification of a plurality of SPS configurations in the second set that are simultaneously activatable. For example, the first list is called a configuredgrantconfigutype 2ActivationStateList (configuration grant type2activation state list), and the second list is called a SPS-configcactionstatelist (SPS configuration activation state list), not limited to the illustrated example.

For example, configuring the UE with the configurable grantconfigurtype 2 activity statelist through RRC/MAC signaling indicates a first activation option corresponding to CG configuration that can be activated simultaneously or configuring the SPS-configurable activity statelist indicates a second activation option corresponding to SPS configuration that can be activated simultaneously. A terminal may connect to multiple cells simultaneously, and different cells may correspond to different first activation options or second activation options.

In some embodiments, the resource activation information is carried through DCI signaling, and the first indication information is indication information corresponding to a first activation option in a configured GrantConfigType2 ActionStateList (first list); and/or the second indication information is indication information corresponding to a second activation option in the sps-configActionStateList (second list); and/or the third indication information is indication information corresponding to the first activation option in the configured GrantConfigType2 ActionStateList and the second activation option in the sps-ConfigActionStateList.

In some embodiments, the first indication information is indication information of whether the first activation option in the configurable GrantConfigType2 ActionStateList is activated or not, or the first indication information is a mapping value of one or more first activation options in the configurable GrantConfigType2 ActionStateList; the second indication information is indication information of whether the second activation options in the sps-ConfigActionStateList are activated or not, or the second indication information is a mapping value of one or more second activation options in the sps-ConfigActionStateList; the third indication information is indication information of whether the first activation option in the configured GrantConfigType2 ActiveStateList is activated or not and whether the second activation option in the sps-ConfigActiveStateList is activated or is indication information of mapping values of one or more first activation options in the configured GrantConfigType2 ActiveStateList and mapping values of one or more second activation options in the sps-ConfigActiveStateList.

For example, the first indication information is 0 or 1,0 indicates that the first activation option in the configured GrantConfigType2 ActiveStateList is not activated, and 1 indicates that the first activation option in the configured GrantConfigType2 ActiveStateList is activated.

For another example, the resource configuration information includes 5 CG configurations, and the sequence numbers (identifiers) of the CG configurations are 0,1,2,3, and 4, respectively; the resource configuration information further includes configurable GrantConfigType2 ActionStateList that may include {0,3}, and that represents CG configuration with sequence number 0 and CG configuration with sequence number 3 may be activated at the same time. At this time, the first indication information may be a 1bit information indication, which indicates that the CG configuration of the sequence number 0 and the CG configuration of the sequence number 3 are simultaneously activated according to the configurable grantconfigurtype 2 activity statelist.

For another example, the configurable GrantConfigType2 Activity State List may include { {1,2}, {0,1}, {2,5}, representing CG configurations numbered 1 and 2 may be activated simultaneously, CG configurations numbered 0 and 1 may be activated simultaneously, and CG configurations numbered 2 and 5 may be activated simultaneously. At this time, the first indication information may be 2bit information indication, and the predefined mapping relationship is that the 2bit information is used to indicate a certain first activation option. 00 indicates that the 1 st first activation option {1,2} (i.e., CG configuration with both serial number 1 and serial number 2) is activated, 01 indicates that the 2 nd first activation option {0,1} (i.e., CG configuration with both serial number 0 and serial number 1) is activated, and 10 indicates that the 3 rd first activation option {2,5} (i.e., CG configuration with both serial number 2 and serial number 5) is activated.

In some embodiments, the first indication information is indication information corresponding to a plurality of CG configurations in the first set, or the first indication information is indication information corresponding to a third activation option, where the third activation option includes an identifier of a plurality of CG configurations that can be activated simultaneously in the first set; the second indication information is indication information corresponding to a plurality of SPS configurations in the second set, or the second indication information is indication information corresponding to a fourth activation option, wherein the fourth activation option comprises identifiers of a plurality of SPS configurations which can be activated simultaneously in the second set; the third indication information is indication information corresponding to one or more CG configurations and one or more SPS configurations in the third set, or the third indication information is indication information corresponding to a fifth activation option, where the fifth activation option includes an identifier of one or more CG configurations and an identifier of one or more SPS configurations in the third set that can be activated simultaneously.

Further, the resource activation information may be carried through DCI signaling, where the first indication information is an identifier configured by multiple CGs in the first set, or the first indication information is a mapping value of the identifier configured by multiple CGs in the first set, or the first indication information is an index value of a third activation option in a first predefined table, where the first predefined table includes multiple third activation options, and each third activation option includes an identifier configured by multiple CGs that may be activated simultaneously in the first set.

The second indication information is the identification of a plurality of SPS configurations in the second set, or the second indication information is the mapping value of the identification of a plurality of SPS configurations in the second set, or the second indication information is the index value of a fourth activation option in a second predefined table, wherein the second predefined table comprises a plurality of fourth activation options, and each fourth activation option comprises the identification of a plurality of SPS configurations which can be activated simultaneously in the second set.

The third indication information is the identifier of one or more CG configurations and the identifier of one or more SPS configurations in the third set, or the third indication information is a mapping value of the identifier of one or more CG configurations and the identifier of one or more SPS configurations in the third set, or the third indication information is an index value of a fifth activation option in a third predefined table, where the third predefined table includes a plurality of fifth activation options, and each fifth activation option includes the identifier of one or more CG configurations and the identifier of one or more SPS configurations that can be activated simultaneously in the third set.

For example, when there is no higher layer signaling configuration sps-configmactivationstatelist/configuredgrantconfilgtype 2 ActivationStateList. The resource activation information may be carried by DCI signaling, where the first indication information carried may be a plurality of CG configured identifiers, for example, the identifier may be a sequence number, and direct indicates that CG configurations with sequence numbers 1 and 3 are activated simultaneously; or mapping values of serial numbers of a plurality of CG configurations, for example, the serial numbers of the CG configurations are encoded by using a traditional digital addition/subtraction/RIV binary tree and other calculation methods, and the encoding results are indicated; or a table (first predefined table) of CG configurations that can be activated simultaneously is predefined by the standard, including a plurality of third activation options, an index value of 0 representing CG configurations with simultaneous activation numbers of 0 and 1 (third activation option), an index value of 1 representing CG configurations with simultaneous activation numbers of 1 and 2 (third activation option), and an index value of 3 representing CG configurations with simultaneous activation numbers of 2 and 3 (third activation option). The terminal may be connected to multiple cells simultaneously, and different cells may correspond to different third activation options, fourth activation options, or fifth activation options. The identity may also be other information in the cell configuration that may indicate CG configuration, such as: CG type, etc.

In some embodiments, the resource activation information is carried by a newly added field in the DCI format and/or the resource activation information is carried by an existing field in the DCI format.

For example, a DCI format (format) including HARQ process number (hybrid automatic repeat request process number) field or RV (redundancy version) field, etc. may be used to carry the resource activation information. One or more fields may be added to the DCI format to carry the resource activation information.

The resource configuration information is carried by RRC/MAC CE (Control Element) signaling, and the activation of a plurality of SPS configurations and/or CG configurations is indicated by DCI sending resource activation information, so that DCI signaling load can be remarkably reduced, and the existing DCI format field configuration is reused without increasing PDCCH blind detection complexity.

The positional offset relationship configuration is specifically described below.

In some embodiments, the location offset relationship configuration is carried by at least one of RRC signaling, MAC signaling, and DCI. Further, the priority of the positional offset relation configuration carried in the DCI, the positional offset relation configuration carried in the MAC signaling, and the positional offset relation configuration carried in the RRC signaling decreases in order.

For example, the configuration of the positional offset relationship may be configured using RRC signaling, or configured using MAC CE (Control Element) signaling, or configured using DCI signaling; the configuration may also be performed using both RRC signaling and DCI signaling, or using both RRC signaling and MAC CE signaling, or using both MAC CE signaling and DCI signaling, or using both RRC signaling and MAC CE signaling and DCI signaling. For example, when configuration is performed using RRC signaling and MAC CE signaling and DCI signaling at the same time, DCI signaling covers RRC signaling and MAC CE signaling, and MAC CE signaling covers RRC signaling. Since the DCI signaling is more real-time than other signaling and can be dynamically changed, the DCI signaling configuration may provide a possibility for performing dynamic adjustment and optimization of the SPS configuration.

In some embodiments, the positional offset relationship configuration is carried by a newly added field (field) in the DCI format and/or the positional offset relationship is carried by an existing field (field) in the DCI format. The positional offset relationship includes: at least one of a time offset relationship and a frequency offset relationship.

Further, in some embodiments, in the case where the resource activation information includes the first indication information, the positional offset relationship configuration includes: indication information corresponding to a first position offset option, where the first position offset option includes: simultaneously activating a plurality of CG configuration corresponding CG transmission position offset in the first set; and/or in the case that the resource activation information includes the second indication information, the positional offset relationship configuration includes: indication information corresponding to a second position offset option, the second position offset option including: simultaneously activating position offset between SPS transmissions corresponding to a plurality of SPS configurations in a second set; and/or in case the resource activation information includes third indication information, the positional offset relation configuration includes: indication information corresponding to a third position offset option, where the third position offset option includes: simultaneously activating position offset between CG transmission corresponding to one or more CG configuration and SPS transmission corresponding to one or more SPS configuration in a third set; the first position offset option, the second position offset option and the third position offset option are set in the same or different preset resource position offset tables or sets, and the position offset comprises: at least one of a time offset and a frequency offset. The preset resource location offset table or set may include one or more first location offset options, and/or one or more second location offset options, and/or one or more third location offset options.

For example: the preset resource position offset table comprises a plurality of offset options, and the subsequent columns respectively comprise at least one of the following configurations: slot offset, symbol offset, frequency offset (counted in RBs, counted in RB groups RBG), carrier offset (in-band/inter-band carrier sequence number offset). The preset resource position offset table comprises N rows, each row has a unique index value, and the preset resource position offset table has N position offset options. The indication information of the position offset option may be an index value of the preset table. In addition, there may be a plurality of preset resource location offset tables, which are configured by the network to adapt to different deployment scenarios and spectrum resources. When the configuration columns included in the preset resource position offset table are fewer, for example, only including slot offset or only including frequency offset, the preset table can be regarded as a set, elements in the set are position offset options, and the position offset option indication value is used for indicating the position of the selected position offset option in the set.

In other embodiments, in the case where the resource activation information includes the first indication information, the positional offset relationship configuration includes: simultaneously activating a plurality of CG configuration corresponding CG transmission position offset in the first set; and/or in the case that the resource activation information includes the second indication information, the positional offset relationship configuration includes: simultaneously activating position offset between SPS transmissions corresponding to a plurality of SPS configurations in a second set; and/or in case the resource activation information includes third indication information, the positional offset relation configuration includes: simultaneously activating position offset between CG transmission corresponding to one or more CG configuration and SPS transmission corresponding to one or more SPS configuration in a third set; wherein the positional offset includes: at least one of a time offset and a frequency offset.

The position offset may be a direct indication of at least one of slot offset, symbol offset, frequency offset (counted in RBs, counted in RB groups RBGs), carrier offset (in-band/inter-band carrier sequence number offset). For example: n bits are used to indicate a specific value of the slot offset or a specific value of the RBG offset.

For example, an SPS/CG Activation Offset (SPS/CG active offset field) field is newly added to the DCI Format to carry a positional offset relationship configuration.

Further, when the resource activation information includes the first indication information, the indication information (index value) corresponding to the first position offset option may be carried through the CG Activation Offset domain, or the position offset between CG transmissions corresponding to the plurality of CG configurations in the first set that is activated at the same time may be directly carried; carrying indication information (index value) corresponding to a second position offset option through SPS Activation Frequency Offset domain when the resource activation information comprises second indication information, or directly carrying position offset among SPS transmission corresponding to a plurality of SPS configuration in a second set activated at the same time; in the case that the resource activation information includes the third indication information, the indication information corresponding to the third position offset option is carried through the CG Activation Offset domain and the SPS Activation Frequency Offset domain, or the position offset between the CG transmission corresponding to the one or more CG configurations and the SPS transmission corresponding to the one or more SPS configurations in the third set that is activated at the same time is directly carried.

Further, SPS/CG Activation Offset may include SPS/CG Activation Frequency Offset and SPS/CG Activation Time Offset domains, carrying frequency and time offsets, respectively, or frequency and time offset indication, respectively. For example, in the case where the resource activation information includes the first indication information, the frequency offset between CG transmissions corresponding to the plurality of CG configurations in the first set that is activated simultaneously may be directly carried by the CG Activation Frequency Offset field, the time offset between CG transmissions corresponding to the plurality of CG configurations in the first set that is activated simultaneously may be directly carried by the CG Activation Time Offset field, or the indication information (index value) corresponding to the first location offset option may be carried by the CG Activation Time Offset field through the CG Activation Frequency Offset field, or the indication information (index value) corresponding to the time offset option and the frequency offset option in the first location offset option may be respectively carried by the CG Activation Time Offset field through the CG Activation Frequency Offset field. The time offset in the first position offset option corresponds to the time offset option, and the frequency offset corresponds to the frequency offset option.

For another example, the existing domain carrying positional offset relation configuration in DCI format 1_1 or 0_1 is reused. Further, a preset bit may be added to the FDRA (Frequency Domain Resource Allocation ) domain and/or a preset bit at the end may be used to indicate the frequency offset relationship, and/or a preset bit may be added to the TDRA (Time Domain Resource Allocation ) domain and/or a preset bit at the end may be used to indicate the time offset relationship. Reference may be made specifically to the above embodiments, and details are not repeated.

The method of the above embodiment may use the same location offset configuration mode or different location offset configuration modes for different network deployment scenarios (single carrier/multi carrier, carrier aggregation/multi connection, 5G NR/5G-Advanced/6G, FDD/TDD). The position offset configuration mode is flexibly configured according to the network deployment scene and service requirements, so that signaling load can be saved, and the requirements of different scenes and services can be met.

The CG transmissions or the positional offset relationships between SPS transmissions corresponding to the CG configurations or the SPS configurations may be compared and described according to the positions indicated by the minimum resource number values of the time domain and/or the frequency domain.

The CG configurations or SPS configurations may correspond to CG transmissions or time and/or frequency domain resources occupied on SPS transmissions that are the same or different in size, e.g.: may have different transport block sizes TB size, different modulation coding scheme MCS levels, etc. Therefore, the scheme has more flexibility and expandability of configuration, and is suitable for different configuration situations.

When one or more CG configurations and one or more SPS configurations need to be activated simultaneously, for the conventional LTE/NR standard, since simultaneous co-frequency full duplex is not supported, the configuration of the position offset relationship is limited to configuring the position offset relationship between CG configurations or between SPS configurations; or in the FDD, different CG and SPS configurations can be configured aiming at the time domain position offset relation in different frequency bands; or when in TDD, different CG and SPS are configured in different time slots, and the configuration can be carried out aiming at the frequency domain position offset relation. When supporting flexible duplex/same frequency full duplex, the 5G-Advanced and 6G communication systems can flexibly configure the position offset relation between CG configuration or SPS configuration. Therefore, the scheme is suitable for different duplex modes, can be particularly expanded to future 5G-Advanced and 6G communication systems, and has the flexibility and expandability of configuration. In addition, the scheme can meet a plurality of possible resource allocation schemes on a single carrier.

In some embodiments, the configuration of the positional offset relationship in the signaling carrying the resource allocation configuration information sent by the base station is different for each reception by the terminal. If the positional offset relation configuration is already configured before, the positional offset relation configuration may not be carried in the resource allocation configuration information.

The offset relationship configuration may be an option in the resource allocation configuration information. For example, when the base station has previously configured multiple activated SPS configurations for the UE and subsequently deactivated the multiple SPS configurations due to network load or traffic demands, the base station may send resource allocation configuration information for the UE, where the resource allocation configuration information may not include a location offset relationship configuration, and the time-frequency resources and/or the location offset relationship configuration of the multiple SPS configurations that are activated may use past configuration information.

In step S104, the terminal performs uplink transmission using the resources corresponding to the activated multiple CG configurations, and/or receives downlink data using the resources corresponding to the activated multiple SPS configurations.

In the above embodiment, the terminal receives the signaling carrying the resource allocation configuration information sent by the base station, where the resource allocation configuration information includes the resource activation information and the position offset relation configuration, and may also include the resource configuration information. The simultaneous activation of a plurality of CG configurations or a plurality of SPS configurations or the simultaneous activation of CG configurations and SPS configurations can be realized through the resource configuration information, and the flexible configuration of the position offset relation can be carried out for CG transmission corresponding to the CG configurations and/or SPS transmission corresponding to the SPS configurations which are simultaneously activated, so that the terminal can transmit uplink data or receive downlink data on the activated resources, the characteristics of XR service multiflow and variable packet size can be better adapted, the utilization rate of system resources can be improved, the requirements of XR service low time delay high reliability can be met, and the service QoS (quality of service)/QoE (quality of experience) can be guaranteed.
