Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 2, fig. 2 is a network schematic diagram applicable to the embodiment of the present invention, as shown in fig. 2, including a terminal 11 and a network side Device 12, where the terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), or a web-enabled Device (web-enabled Device), and the embodiment of the present invention is not limited to the specific type of the user terminal 11. The network side device 12 may be a macro station, an LTE eNB, a 5G NR gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, etc., or the network side device 12 may be an Access Point (AP); the network-side device 12 may also be a network node formed by a Central Unit (CU) and a plurality of transmission and reception points (Transmission Reception Point, TRP) managed and controlled by the Central Unit. It should be noted that, in the embodiment of the present invention, the specific type of the network side device 12 is not limited.
Referring to fig. 3, fig. 3 is a flowchart of a method for selecting a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resource, provided by an embodiment of the present invention, applied to a transmission node, as shown in fig. 3, where the method for selecting a PUSCH resource includes the following steps:
Step 301, if downlink control information DCI triggers reporting of aperiodic CSI, selecting a first PUSCH resource meeting a first requirement from a PUSCH resource set scheduled by the DCI, where the first PUSCH resource is used to carry the aperiodic CSI.
Here, if the DCI triggers CSI reporting, the terminal may select the first PUSCH resource in the PUSCH resource set scheduled by the DCI according to the first requirement, so that the determined PUSCH resource for carrying aperiodic CSI is more suitable, and the success rate, reliability and flexibility of CSI reporting are improved.
It should be noted that, in the uplink Multi-TTI scheduling mechanism or PUSCH aggregate transmission scenario, when the downlink control information (Downlink Control Information, DCI) of the uplink scheduling triggers reporting of downlink aperiodic channel state information (Channel Status Information, CSI), a single DCI may schedule multiple slots (Slot) or minislots (Mini-Slot) at a time, and each Slot or minislot corresponds to one PUSCH resource, i.e., the DCI may schedule a PUSCH resource set including multiple PUSCH resources, and therefore, the transmission node needs to select one or multiple PUSCH resources (i.e., a first PUSCH resource) for carrying aperiodic CSI from multiple PUSCH resources in the PUSCH resource set.
In addition, the transmission node may include any one of a terminal, a network side device, and a wireless access node (WIFI-AP), for example, when the transmission node is a terminal, the terminal may select a first PUSCH resource in the PUSCH resource set scheduled by the DCI to meet a first requirement, and send the aperiodic CSI on the first PUSCH resource; and when the transmission node is a network side device, the network side device may select a first PUSCH resource satisfying a first requirement from the PUSCH resource set scheduled by the DCI, receive the aperiodic CSI on the first PUSCH resource, and so on.
In step 301, in the case that the DCI triggers aperiodic CSI reporting, the transmission node may select a first PUSCH satisfying the first requirement from the PUSCH resource set scheduled by the DCI.
In this embodiment, the first requirement includes at least one of the following:
aperiodic CSI processing time requirements;
transmission time slot requirements of PUSCH resources;
aperiodic CSI data volume requirements;
business scene requirements corresponding to the PUSCH resource bearing data;
PUSCH resources carry uplink control information (Uplink Control Information, UCI) requirements, etc.
Accordingly, selecting the first PUSCH resource satisfying the first requirement in the set of PUSCH resources scheduled by the DCI includes the following multiple implementations:
In a first aspect, when the first requirement includes the aperiodic CSI processing time requirement, the transmission node selects PUSCH resources that occupy a first symbol that is not earlier than the first symbol and/or a second symbol after considering an effect of timing advance in the PUSCH resource set, that is: in the case that the first requirement includes the aperiodic CSI processing time requirement, the first PUSCH resource satisfies:
the occupied first symbol is not earlier than the first symbol and/or the second symbol after considering the effect of the timing advance.
Specifically, a first symbol occupied by the first PUSCH resource is not earlier than the first symbol; or the first symbol occupied by the first PUSCH resource is not earlier than the second symbol; or, the first symbol occupied by the first PUSCH resource is not earlier than the earlier symbol in the first symbol and the second symbol.
In one aspect, the first symbol is: shifting a first uplink symbol after a first duration relative to the end time of triggering DCI, wherein the first symbol is Zref; the second symbol is: the first uplink symbol after the second duration is offset relative to the end time of the last symbol occupied by the latest resource in the used aperiodic measured resources.
It should be noted that, the first duration may be calculated according to the following calculation formula (1):
T proc,CSI ＝(Z)(2048+144)·κ2 -μ ·T C (1)
and, the second time period may be calculated according to the following calculation formula (2):
T proc,CSI ＝(Z′)(2048+144)·κ2 -μ ·T C (2)
wherein the time unit T c ＝1/(Δf max ·N f )，Δf max ＝480·10 3 Hz (hertz), N f =4096, constant κ=t s /T c =64, where T s ＝1/(Δf ref ·N f,ref )，Δf ref ＝15·10 3 Hz，N f,ref ＝2048；
Mu is given as min (mu) PDCCH ,μ CSI-RS ,μ UL ) Here μ PDCCH For subcarrier spacing, mu, of PDCCH (Physical Downlink Control Channel ) carrying said DCI UL For the subcarrier interval, mu, corresponding to the scheduled PUSCH resource set CSI-RS A minimum subcarrier spacing for aperiodic CSI-RS (CSI Reference Signal ) transmission triggered by the DCI;
z and Z' can be agreed by a protocol or preconfigured by a network side according to different conditions;
in addition, the above-mentioned Z and Z' may be valued based on μ with reference to the following Table 1 or Table 2 under different conditions.
Table 1, Z and Z' values are shown in Table 1
Table 2, Z and Z' show a comparison of values
In a second aspect, when the first requirement includes a requirement for a transmission slot of a PUSCH resource, the transmission node selects, in the PUSCH resource set, PUSCH resources in L slots at a tail end of the scheduled N slots, where all occupied symbols are located, that is: in the case that the first requirement includes a transmission slot requirement of the PUSCH resource, the first PUSCH resource satisfies: all occupied symbols are positioned in L time slots at the tail part of N time slots, wherein N is a positive integer, and L is a positive integer smaller than or equal to N.
In the second mode, PUSCH resources in L slots at the tail of the N slots of the schedule may be all the symbols occupied by the selection: all the PUSCH resources in the PUSCH resource set are the PUSCH resources scheduled in the N time slots, the transmission node acquires the time slot of each PUSCH resource in the PUSCH resource set, and selects the PUSCH resource in the L time slots with the time slots at the tail as the first PUSCH resource.
Wherein, the value of L may be agreed or configured by a protocol, or in some embodiments, L may be equal to:
the minimum value in N and Lref is used as a nominal PUSCH resource to select a slot range, and is used to limit the selection of a first PUSCH resource in a subset of slots located in a certain range at the tail of the slot set scheduled by the DCI, so as to ensure the success probability of the aperiodic CSI transmission, where Lref is a value agreed by a protocol or configured by a network side, for example, when the transmission node is a terminal, lref may be configured by a network side device to the terminal through a higher layer signaling; or alternatively
The value corresponding to the N may be agreed by a protocol or configured by the network side, for example, when the transmission node is a terminal, the value may be agreed by a protocol or configured by the network side device through higher layer signaling based on different values or value ranges of the N.
In a third aspect, when the first requirement includes the aperiodic CSI data amount requirement, the transmission node selects, in the PUSCH resource set, a first PUSCH resource according to a capacity of each PUSCH resource in the PUSCH resource set, and specifically, the first PUSCH resource satisfies any one of the following:
the capacity is greater than or equal to the capacity of the remaining PUSCH resources of the PUSCH resource set;
the capacity is greater than or equal to the capacity of the remaining PUSCH resources in the first PUSCH resource subset, the PUSCH resource subset comprising: the first PUSCH resources set meets PUSCH resources of the first requirement, which are required by the first requirement except for the aperiodic CSI data amount requirement;
the capacity is greater than or equal to a capacity threshold;
and the capacity is larger than or equal to the load corresponding to the data volume of the aperiodic CSI.
The first PUSCH resources satisfy the capacity of the remaining PUSCH resources with a capacity greater than or equal to that of the PUSCH resources set, and may be selected from the PUSCH resources set, for example, the PUSCH resources in the PUSCH resources set are sorted in descending order according to the capacity of the PUSCH resources, and the first J PUSCH resources after sorting are selected as the first PUSCH resources, where J may be agreed, configured or preconfigured by a protocol, and so on.
Here, the capacity of the PUSCH resource may be any parameter amount capable of reflecting the data carrying capability of the PUSCH resource, and specifically, the capacity may include any one of the following:
the PUSCH resource is based on the size of a transmission block which can be borne by the protocol flow;
the number of resource elements RE of the data can be mapped by the PUSCH resource;
PUSCH resources may map the number of symbols of data.
Similarly, the first PUSCH resources may be PUSCH resources selected from a first PUSCH resource subset, where the first PUSCH resource subset has a preset number (e.g., J) with the largest capacity; or, in the PUSCH resource set, PUSCH resources with a capacity greater than or equal to a preset number of capacity thresholds (e.g., J) are selected, PUSCH resources with a capacity greater than or equal to a preset number of loads corresponding to the aperiodic CSI data amount (e.g., J) are selected, and the like, which are not limited herein.
Note that, the first PUSCH resource subset includes: and the PUSCH resource set meets the PUSCH resources of other requirements except the CSI data quantity requirement in the first requirement.
For example, in the case that the first condition includes the aperiodic CSI data amount requirement and the PUSCH resource transmission timeslot requirement, the transmission node first selects PUSCH resources in the PUSCH resource set that satisfy the PUSCH resource transmission timeslot requirement to form the first PUSCH resource subset, and then determines, in the first PUSCH resource subset, a preset number of PUSCH resources with the largest capacity as the first PUSCH resources.
In addition, the capacity threshold may be a protocol contract or configuration, and specifically, the capacity threshold may be configured by a network side; or based on the bit number of the first part of content in the aperiodic CSI feedback, wherein the bit number of the first part of content is fixed.
Here, each aperiodic CSI may contain two-Part content, i.e., a first-Part content (Part 1) and a second-Part content (Part 2). Part1 is fixed in number of bits and is used to determine the number of information bits that Part 2 contains, and Part1 requires complete transmission prior to Part 2. The capacity threshold of the PUSCH resource may be calculated based on the number of bits of Part 1.
In this embodiment, the aperiodic CSI may be divided into two types, i.e., a first Type CSI (Type I CSI) and a second Type (Type II CSI), where Type I CSI is used to schedule only a single user on a designated time-frequency resource, and support more layers for parallel transmission; and the Type II CSI is used to schedule multiple users simultaneously on the same time-frequency resource, but the number of layers supported by each scheduled user is limited (at most two layers). Wherein, content contained in Part1 and Part 2 is different based on CSI type:
for Type I CSI feedback, part1 contains a Rank Indication (RI) (if needed to report), a channel state information reference pilot resource Indication (CSI-RS Resource Index, CRI) (if needed to report), and a channel quality Indication (Channel Quality Indicator, CQI) of the first codeword; part 2 contains a precoding matrix indicator (Precoding Matrix Indicator, PMI) (if reporting is required) and a CQI for the second codeword when RI (if reporting is required) is greater than 4;
For Type II CSI feedback, part 1 contains RI (if needed to report), CQI, and an indication of the number of non-zero wideband amplitude factors for each layer; part 2 contains a PMI and Part 1 and Part 2 are encoded separately.
It can be seen that, when the aperiodic CSI includes both Part 1 and Part 2, when the aperiodic CSI data is Type I CSI feedback or Type II CSI feedback, the number of bits of Part 2 is uncertain and related to factors such as the reported Rank value, so that the terminal and the network device understand that there is a possibility of inconsistency, and when the terminal selects a certain or some first PUSCH resources to carry the aperiodic CSI according to the load amount corresponding to a certain value of the aperiodic CSI data amount, the network side may select other single or multiple first PUSCH resources to receive the aperiodic CSI according to the load amount corresponding to other values of the aperiodic CSI data amount, which results in unsuccessful transmission of the aperiodic CSI.
Therefore, the above-mentioned first PUSCH resource may satisfy a load amount with a capacity greater than or equal to the load amount corresponding to the aperiodic CSI data amount, where the terminal and the network device understand that the load amount corresponding to the aperiodic CSI data amount is consistent.
Wherein, the above terminal and the network device understand that there is agreement, and may be that when the reporting amount parameter (e.g. reportquality) configured by the higher layer is configured to be a first value (e.g. cri-RSRP) or a second value (e.g. ssb-Index-RSRP), the CSI feedback only includes a single Part, does not distinguish Part1 from Part2, and has a fixed number of bits, so that the terminal and the network device understand agreement.
In a fourth aspect, when the first requirement includes a traffic scenario requirement corresponding to PUSCH resource bearer data, the transmission node selects PUSCH resources corresponding to or not corresponding to a required traffic scenario or a traffic scenario set, from among the plurality of PUSCH resources in the PUSCH resource set, that is: the first PUSCH resource satisfies: and the PUSCH resource is corresponding or not corresponding to the first service scene, wherein the first service scene is a required service scene or a service scene set.
For example, in the case that the traffic scenario requirement corresponding to the PUSCH bearer data is a certain traffic scenario or a certain traffic scenario, and the DCI carries a traffic scenario corresponding to the data indicating that each PUSCH resource is carried, or the transmission node learns, through a predefined rule, the traffic scenario corresponding to the data carried by each PUSCH resource, and then the transmission node may select, as the first PUSCH resource, a PUSCH resource corresponding to a traffic scenario required by the traffic scenario requirement corresponding to the PUSCH bearer data for the traffic scenario.
It should be noted that the service scenario may include an enhanced mobile broadband (Enhanced Mobile Broadband, eMBB) scenario, or an Ultra-low latency communication (URLLC) scenario, or the like.
In a fifth aspect, when the first requirement includes a PUSCH resource bearer uplink control information UCI requirement, the transmission node selects, in the PUSCH resource set, a PUSCH resource that meets a PUSCH resource bearer UCI requirement, and specifically, when the first requirement includes the PUSCH resource bearer UCI requirement, if a protocol specifies, configures, or schedules a second PUSCH resource bearer UCI, then: selecting the first PUSCH resources only outside the second PUSCH resources; or allowing the first PUSCH resource to be selected from the second PUSCH resources.
In a fifth aspect, in the case where the protocol specifies, configures, or schedules the second PUSCH resources in the PUSCH resources set to carry UCI, and only allows PUSCH resources to be selected except for the second PUSCH resources, the transmission node may select only the first PUSCH resources from the remaining PUSCH resources in the PUSCH resources set except for the second PUSCH resources, that is, the selected first PUSCH resources do not carry UCI; or, in the case that the protocol specifies, configures or schedules the second PUSCH resource bearer UCI in the PUSCH resource set, and allows the PUSCH resource to be selected from the second PUSCH resources, the transmission node may select the first PUSCH resource from the second PUSCH resources, or may also select the first PUSCH resource from PUSCH resources other than the second PUSCH resource, that is, allow the selected first PUSCH resource to carry UCI.
Note that the UCI described above refers to some other type of UCI than the aperiodic CSI described above, or other specified UCI of various types, or all other UCI. Other UCI of some type or other specified UCI of various types may be agreed by the protocol or the network side may be preconfigured to the terminal through higher layer signaling.
In this embodiment, the first requirement may include one or more requirements of the aperiodic CSI processing time requirement, a transmission time slot requirement of a PUSCH resource, an aperiodic CSI data amount requirement, a traffic scenario requirement corresponding to PUSCH resource bearer data, and a PUSCH resource bearer UCI requirement, and in the case that the first requirement includes multiple requirements, the selection of the first PUSCH resource should be implemented in a manner corresponding to the multiple requirements in the first to fifth modes.
For example, in the case where the first requirement includes a transmission slot requirement of PUSCH resources, an aperiodic CSI data amount requirement, and a PUSCH resource bearer UCI requirement, the first PUSCH resources satisfy: all occupied symbols are positioned in L time slots at the tail part of the N time slots of the scheduling, UCI is not carried, and the capacity is larger than or equal to the capacity of the rest PUSCH resources in the PUSCH resource set.
In addition, in the case where the first request includes a plurality of requests, the transmission node may select the first PUSCH resource according to the plurality of requests, and there may be no order of screening between the requests. For example, in the case where the first requirement includes a transmission time slot requirement of a PUSCH resource and an aperiodic CSI data amount requirement, the PUSCH resource satisfying the transmission time slot requirement of the PUSCH resource may be selected first, and then the PUSCH resource satisfying the CSI data amount requirement is selected as the first PUSCH resource from the PUSCH resources satisfying the transmission time slot requirement of the PUSCH resource; or, the PUSCH resource meeting the requirement of the aperiodic CSI data amount may be selected first, and then the PUSCH resource meeting the requirement of the transmission time slot of the PUSCH resource is selected as the first PUSCH resource from the PUSCH resources meeting the requirement of the aperiodic CSI data amount.
Of course, the transmission node may also configure the filtering sequence of the requirements according to protocol convention or in advance, for example, in the case that the first requirement includes an aperiodic CSI data amount requirement and other requirements (such as at least one of an aperiodic CSI processing time requirement, a transmission time slot requirement of a PUSCH resource, a traffic scenario requirement corresponding to PUSCH resource bearing data, and a PUSCH resource bearing UCI requirement), other requirements may be preferentially considered, and then the aperiodic CSI data amount requirement is considered, that is: and selecting a PUSCH resource subset meeting other requirements from the PUSCH resource set, and selecting a first PUSCH resource meeting the aperiodic CSI data amount requirement from the PUSCH resource subset meeting other requirements.
In some embodiments, in the case that the first requirement includes the data amount requirement of the aperiodic CSI, if the first requirement further includes a PUSCH resource carrying UCI requirement, the capacity is a remaining capacity after deducting the specified type of UCI, or specified multiple types of UCI, or capacity occupied by transmission of all UCI, so that the determined PUSCH resource for carrying the aperiodic CSI is more suitable, and further, transmission reliability of the aperiodic CSI is improved.
Here, in the case that the first requirement includes the aperiodic CSI data amount requirement and the PUSCH resource bearer UCI requirement, the transmission node may first select, in the PUSCH resource set, a PUSCH resource that satisfies the PUSCH resource bearer UCI requirement, and in the case that a PUSCH resource that satisfies the PUSCH resource bearer UCI requirement also carries UCI, the transmission node may then calculate a capacity of each PUSCH resource that also carries UCI in a process of selecting a first PUSCH resource that satisfies the aperiodic CSI data amount requirement from the PUSCH resources that satisfy the PUSCH resource bearer UCI requirement, where the capacity is a remaining capacity after subtracting a capacity occupied by UCI of a specified type, or UCI of a specified multiple types, or all UCI transmissions, and select the first PUSCH resource according to a remaining capacity of each PUSCH resource, for example, select a PUSCH resource with a remaining capacity greater than or equal to a capacity threshold, and so on.
It should be noted that, the first PUSCH resources may be directly selected according to the first requirement, or in some embodiments, the selecting, in the PUSCH resource set, the first PUSCH resources that meet the first requirement includes: determining a second PUSCH resource subset meeting the first requirement in the PUSCH resource set; and determining the first PUSCH resource in the second PUSCH resource subset, so that the selected PUSCH resource used for bearing the aperiodic CSI is more suitable.
Wherein the determining the first PUSCH resources in the second PUSCH resource subset may be selecting the first PUSCH resources in the second PUSCH resource subset satisfying the first requirement according to a second requirement, and the second requirement may be other requirements besides the first requirement.
Specifically, the first PUSCH resource may be: and M PUSCH resources with the transmission time later in the second PUSCH resource subset, wherein M is a positive integer.
Here, after determining the second PUSCH resource subset satisfying the first requirement, the transmission node may select M PUSCH resources having a transmission time later in the second PUSCH resource subset as the first PUSCH resources. Wherein, the M can be protocol convention or network side configuration.
For example, if the second PUSCH resource subset is determined according to the aperiodic CSI data amount requirement, if the second PUSCH resource subset includes a plurality of PUSCH resources with equal capacity, the transmission node may select PUSCH resources with M transmission times later from the plurality of PUSCH resources with equal capacity as the first PUSCH resource.
It should be noted that, the number of PUSCH resources in the second PUSCH resource subset may be less than the M, in which case the first PUSCH resource may be: and all the PUSCH resources in the second PUSCH resource subset.
Referring to fig. 4, a schematic structural diagram of a transmission node according to an embodiment of the present invention is shown in fig. 4, where, as shown in fig. 4, the transmission node 400 includes:
a processing module 401, configured to select, in a PUSCH resource set scheduled by DCI, a first PUSCH resource meeting a first requirement if downlink control information DCI triggers reporting of aperiodic CSI, where the first PUSCH resource is used to carry the aperiodic CSI;

Alternatively, the occupied first symbol may be no earlier than the first symbol and/or the second symbol after considering the effect of the timing advance.
