Description

Information determination method and device, and communication equipment Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to an information determination method and apparatus, and a communication device. Background Art

[0002] The Transport Block Size (TBS) corresponding to a channel is determined based on the resource quantity of the channel's transmission resources. For semi-statically configured channels, the channel is periodically transmitted, and the resource quantity of the transmission resources of each periodically transmitted channel is the same, that is, the TBS of each periodically transmitted channel is the same. However, different periodically transmitted channels may have differences, such as different available resources. The current method of determining the TBS of a channel does not take into account the differences in the channels, resulting in inaccurate TBS.

[0035] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0036] SPS PDSCH

[0037] The physical downlink shared channel (PDSCH) can be a semi-static transmission, and the PDSCH of semi-static transmission is also called Semi-Persistent Scheduling (SPS) PDSCH. For SPS PDSCH, the network side pre-configures the transmission resources through Radio Resource Control (RRC) signaling, and then activates the transmission resources through Downlink Control Information (DCI) signaling. The terminal device can then periodically transmit SPS PDSCH on the pre-configured transmission resources, and the number of resources included in the transmission resources of each SPS PDSCH is the same. Among them, the parameters configured when the RRC signaling pre-configures the transmission resources include but are not limited to at least one of the following: Configured Scheduling-Radio Network Temporary Identity (CS-RNTI), periodicity, number of HARQ processes (nrofHARQ-Processes), and HARQ process offset (harq-ProcID-Offset). After the network side preconfigures and activates the transmission resources, the time slots in which the periodic transmission resources (i.e., SPS PDSCH resources) appear are determined based on the following formula:

[0038] (numberOfSlotsPerFrame×SFN+slot number in the frame)=[(numberOfSlotsPerFrame×SFN start time +slotstart time)+N×periodicity×numberOfSlotsPerFrame / 10]modulo(1024×numberOfSlotsPerFrame)

[0039] Among them, numberOfSlotsPerFrame represents the number of time slots included in a radio frame, SFN represents the radio frame number, slot number in the frame represents the time slot number in which the SPS PDSCH resource appears in a radio frame, SFN start time Slotstart time and slotstart time represent the frame and time slot numbers of the first SPS PDSCH after the transmission resource is activated. Periodicity represents the period. The time slot number of the first SPS PDSCH is indicated by DCI signaling (which is used to activate the transmission resource). The time slots of subsequent periodic SPS PDSCHs are determined using the above formula.

[0040] In some embodiments, the optional period of SPS PDSCH transmission is {10, 20, 32, 40, 64, 80...} ms. These periods are mainly used to support Voice over IP (VoIP) services. In some embodiments, to support Ultra-Reliable and Low-Latency Communications (URLLC) services, the period of SPS PDSCH transmission supports a period configuration of at least one time slot. For example, the optional period supported by 15 kHz is {1...640} slot, the optional period supported by 30 kHz is {1...1280} slot, the optional period supported by 60 kHz is {1...2560} slot, and the optional period supported by 120 kHz is {1...5120} slot.

[0041] CG PUSCH

[0042] The Physical Uplink Shared Channel (PUSCH) can be semi-statically transmitted. The semi-statically transmitted PUSCH is also known as the Configured Grant (CG) PUSCH. CG PUSCH includes the following two types:

[0043] Type-1 CG PUSCH: For type-1 CG PUSCH, after the network side pre-configures the transmission resources through RRC signaling, the transmission resources take effect without the need for DCI activation.

[0044] Type-2 CG PUSCH: For type-2 CG PUSCH, after the network side pre-configures transmission resources through RRC signaling, the transmission resources need to be activated by DCI to take effect. The operation mode of type-2 CG PUSCH is basically the same as that of SPS PDSCH. Please refer to the previous description of SPS PDSCH.

[0045] In some implementations, the period of CG PUSCH transmission supports {2, 7} symbols and {1, 2, 4, 5, 8, 10, 16, 20, 32, 40...} slots.

[0046] NR frame structure

[0047] NR uses a 10ms frame length, with a frame containing 10 subframes. Five subframes make up a half-frame, with subframes numbered 0 to 4 and subframes numbered 5 to 9 in different half-frames.

[0048] The NR frame structure is based on time slots. Each time slot in the basic frame structure can be divided into the following three categories: uplink time slot, downlink time slot, and flexible time slot. In the case of a conventional cyclic prefix (CP), each time slot contains 14 symbols. In the case of an extended CP, each time slot contains 12 symbols. The symbols in each time slot can be divided into the following three categories: downlink symbols, uplink symbols, and flexible symbols. Depending on the actual scheduling of the base station, flexible symbols can be used to transmit downlink data or uplink data, that is, the transmission direction of the symbol is not fixed.

[0049] The configuration of the NR frame structure is flexibly configured by combining semi-static configuration of RRC signaling and dynamic configuration of DCI signaling. Among them, the semi-static configuration of RRC signaling supports two methods: semi-static configuration of cell-specific RRC signaling and semi-static configuration of UE-specific RRC signaling. The dynamic configuration of DCI signaling supports two methods: direct indication of configuration by time slot format indication information (Slot Format Indication, SFI) and configuration determined by DCI scheduling. Among them, for the method of semi-static configuration of NR frame structure, the system configures the frame structure based on the period (which can be understood as the uplink and downlink transmission period, or the TDD uplink and downlink switching period), and there is only one conversion point from downlink resources to uplink resources in each period to ensure that the downlink resources are continuous and the uplink resources are continuous in each period. In some embodiments, the period of the frame structure can be 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 5ms, 10ms.

[0050] XR

[0051] Research projects in extended reality (XR) include scenarios such as augmented reality (AR), virtual reality (VR), mixed reality (MR), and cloud gaming (CG). A key XR service is video streaming, whose arrival rates (measured in frames per second) can be 30fps, 60fps, 90fps, and 120fps. The corresponding video stream periods are 33.33ms, 16.67ms, 11.11ms, and 8.33ms.

[0052] TBS

[0053] The size of the transport block carried by the PDSCH (i.e., TBS) is determined as follows:

[0054] 1. Determine the number of resource elements (REs) included in the PDSCH transmission resources (N RE ).

[0055] 1-1) Determine the number of REs corresponding to one physical resource block (PRB) in the PDSCH transmission resource:

[0056]

[0057] in, Represents the number of subcarriers corresponding to one RB; Represents the number of time domain symbols included in the PDSCH transmission resource; Represents the number of REs included in the demodulation reference signal; This parameter is configured for higher-layer signaling and can be set to 6, 12, or 18 (if this parameter is not configured for higher-layer signaling, it is set to 0).

[0058] 1-2) Determine the number of REs included in the PDSCH transmission resources:

[0059] N RE =min(156,N' RE )·n PRB ;

[0060] Among them, n PRB Indicates the number of PRBs included in the PDSCH transmission resources.

[0061] 2. Calculate N info =N RE ·R·Qm υ, according to N info Determine TBS.

[0062] Here, R represents the coding rate, Q m represents the modulation order, and υ represents the number of transmission layers.

[0063] Here, according to N info Determining TBS can be achieved by following the steps below:

[0064] 2-1) Determine N info Is it less than or equal to 3824? If so, go to step 2-2); if not, go to step 2-3).

[0065] 2-2) Calculation According to N′ info and configuration table to determine TBS.

[0066] 2-3) Calculation Determine whether R is less than or equal to 1 / 4. If so, execute step 2-4); if not, execute step 2-5).

[0067] 2-4) Calculation

[0068] 2-5) Determine N′ info Is it greater than or equal to 8424? If so, go to step 2-6); if not, go to step 2-7.

[0069] 2-6) Calculation

[0070] 2-7) Calculation

[0071] The calculation method of the TBS corresponding to the PUSCH is the same as the calculation method of the TBS corresponding to the PDSCH. The TBS corresponding to the PUSCH can be calculated by referring to the calculation method of the TBS corresponding to the PDSCH.

[0072] As can be seen from the above description, the TBS corresponding to a channel is determined based on the number of resources (i.e., the number of REs) of the transmission resources of the channel. For semi-statically configured channels, the channel is periodically transmitted, and the number of resources of the transmission resources of each periodically transmitted channel is the same, that is, the TBS of each periodically transmitted channel is the same. However, for different periodically transmitted channels, there may be differences, for example, different channels have different available resources. The current method of determining the TBS of a channel does not take into account the differences in channels, resulting in a lack of flexibility in the TBS of the channel.

[0073] Taking XR services as an example, XR services have periodic characteristics, so SPS PDSCH or CG PUSCH is used to transmit XR services. This will help reduce service transmission latency (because there is no need to wait for the DCI of the scheduled service) and reduce the power consumption of terminal devices (because there is no need to detect the DCI of the scheduled service). The optional period of XR services is {33.33ms, 16.67ms, 11.11ms, 8.33ms}, while the lengths of the time slots supported in the NR system are 1ms, 0.5ms, 0.25ms, and 0.125ms. It can be found that the length of the XR service period cannot match the length of the NR time slot as an integer multiple. Therefore, the transmission period of SPS PDSCH or CG PUSCH (referred to as SPS / CG transmission period) cannot match the period of the XR service as an integer multiple. To this end, a solution is proposed. For example, if the XR service period is 16.67ms, the SPS / CG transmission period can be repeated in the form of {17ms, 17ms, 16ms} to maximize the matching of three 16.67ms XR service periods, as shown in Figure 2. The following problems exist when using the method shown in Figure 2 to transmit XR services: Depending on the frame structure and the SPS / CG transmission period, the time domain position (such as time slot or sub-time slot) of the SPS PDSCH or CG PUSCH (abbreviated as SPS / CG) transmission may belong to the flexible time slot. As shown in Figure 3, the TDD uplink and downlink switching period is 5ms, and the uplink and downlink configuration of the NR frame structure is {D, D, D, F, U}, where D represents the downlink time slot, F represents the flexible time slot, and U represents the uplink time slot. Figure 3 illustrates five SPS / CG configurations. Taking the first SPS / CG configuration as an example, the first SPS / CG transmission is located in time slot 0 of the first radio frame, the second SPS / CG transmission is located in time slot 7 of the second radio frame, and the third SPS / CG transmission is located in time slot 0 of the third radio frame. The periods of these three SPS / CG transmissions are {17ms, 17ms, 16ms} respectively. The difference between other SPS / CG configurations and the first SPS / CG configuration is that the starting position of the first SPS / CG transmission is different and has a certain offset. As can be seen from Figure 3, there are three (i.e., the second, fourth, and fifth) SPS / CG configurations that use flexible time slots to transmit SPS / CG. In the NR system, when the transmission position of SPS / CG is a flexible time slot, if the time domain symbols occupied by SPS / CG in the flexible time slot do not have an uplink or downlink conflict (for example, for SPS PDSCH, the time domain symbols it occupies are downlink symbols and / or flexible symbols), the SPS / CG is transmitted normally; if the time domain symbols occupied by SPS / CG in the flexible time slot have an uplink or downlink conflict (for example, for SPS PDSCH, the time domain symbols it occupies have uplink symbols), the SPS / CG is abandoned for transmission.If the non-collision time domain symbols in the flexible time slot (downlink symbols and flexible symbols for SPS PDSCH, uplink symbols and flexible symbols for CG PUSCH) are used as the transmission resources for the XR service, it will cause the problem of insufficient utilization of transmission resources in other time slots (i.e., non-flexible time slots). For example, if the SPS PDSCH is configured to occupy 8 symbols in the time slot according to the non-collision time domain symbols in the flexible time slot, this will result in 14-8=6 symbols not being used in other downlink time slots. It can be seen that if you want to make full use of the transmission resources, whether the SPS / CG is transmitted on a non-flexible time slot or on a flexible time slot, it is necessary to occupy the transmission resources in the time slot to the greatest extent. However, the available resources for SPS / CG transmission on a non-flexible time slot are different from those for SPS / CG transmission on a flexible time slot. If the TBS corresponding to the SPS / CG is determined in the current way, there will be inaccuracies, resulting in the SPS / CG being abandoned for transmission. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0074] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0075] FIG4 is a flow chart of an information determination method provided in an embodiment of the present application. As shown in FIG4 , the information determination method includes the following steps:

[0076] Step 401: The first device determines the TBS corresponding to the first channel based on the resource quantity of the first part of resources; wherein, the transmission resources pre-configured for transmitting the first channel are first transmission resources, the first transmission resources include the first part of resources and the second part of resources, and the second part of resources is not used for the transmission of the first channel.

[0077] In an embodiment of the present application, the first channel is used to transmit service data. The first device can be a receiver of the service data (i.e., a receiver of the first channel) or a sender of the service data (i.e., a sender of the first channel). In some embodiments, the first device is a terminal device. In other embodiments, the first device is a network device.

[0078] In the embodiment of the present application, the TBS corresponding to the first channel refers to the transport block size carried by the first channel.

[0079] In the embodiment of the present application, the transmission resource of the first channel is a first transmission resource preconfigured by the base station. In some embodiments, the first channel is an SPS PDSCH. In other embodiments, the first channel is a CG PUSCH. Here, the SPS PDSCH and CG PUSCH can be understood with reference to the above related descriptions.

[0080] In this embodiment of the present application, the first transmission resource of the first channel includes a first portion of resources and a second portion of resources, wherein the second portion of resources is not used for transmission on the first channel. The first portion of resources may refer to the portion of the first transmission resource excluding the second portion of resources. The first portion of resources is used for transmission on the first channel.

[0081] Here, the first part of resources can also be understood as the available resources in the first transmission resources, that is, the resources that can be used to transmit the first channel; the second part of resources can also be understood as the unavailable resources in the first transmission resources, that is, the resources that cannot be used to transmit the first channel.

[0082] It should be noted that the “transmission resources” or “resources” described in the embodiments of the present application may include at least one of the following resources: time domain symbols (also referred to as symbols for short), PRBs, and REs.

[0083] In some embodiments, the first channel is a downlink channel, such as an SPS PDSCH. The second portion of resources includes at least one of the following resources: uplink transmission resources, resources occupied by a guard interval, resources occupied by a control resource set, resources occupied by a synchronization signal, resources occupied by a broadcast channel, and first pre-configured resources, where the first pre-configured resources are pre-configured resources that cannot be occupied by the downlink channel.

[0084] Here, the uplink transmission resource may include at least one of the following resources: an uplink symbol, an uplink PRB, and an uplink RE.

[0085] Here, the resources occupied by the guard interval may include at least one of the following resources: a time domain guard interval and a frequency domain guard interval. The time domain guard interval is used to avoid interference between uplink and downlink transmissions, and its length may be, but is not limited to, symbol-level. The frequency domain guard interval is used to avoid interference between frequency bands, and its length may be, but is not limited to, PRB-level.

[0086] Here, the first pre-configured resource may be a resource that cannot be occupied by a downlink channel pre-configured by the base station.

[0087] In some embodiments, the first channel is an uplink channel, such as a CG PUSCH. The second portion of resources includes at least one of the following resources: downlink transmission resources, resources occupied by a guard interval, resources occupied by a control resource set, resources occupied by a synchronization signal, resources occupied by a broadcast channel, and second pre-configured resources, where the second pre-configured resources are pre-configured resources that cannot be occupied by the uplink channel.

[0088] Here, the downlink transmission resource may include at least one of the following resources: a downlink symbol, a downlink PRB, and a downlink RE.

[0089] Here, the resources occupied by the guard interval may include at least one of the following resources: a time domain guard interval and a frequency domain guard interval. The time domain guard interval is used to avoid interference between uplink and downlink transmissions, and its length may be, but is not limited to, symbol-level. The frequency domain guard interval is used to avoid interference between frequency bands, and its length may be, but is not limited to, PRB-level.

[0090] Here, the second pre-configured resources may be resources that cannot be occupied by the uplink channel pre-configured by the base station.

[0091] When the base station pre-configures resources that cannot be occupied by downlink channels and resources that cannot be occupied by uplink channels, the resources that cannot be occupied by downlink channels and resources that cannot be occupied by uplink channels can be configured independently.

[0092] In an embodiment of the present application, the first part of resources is the part of resources in the first transmission resources other than the second part of resources. Given that the second part of resources has different distributions in the first transmission resources, the first part of resources can be continuous resources or non-continuous resources.

[0093] In some embodiments, the first portion of resources is continuous resources; in this case, the first channel can use all resources of the first portion of resources for transmission, and accordingly, the first device determines the TBS corresponding to the first channel based on the total resource quantity of the first portion of resources.

[0094] In some embodiments, the first portion of resources is a non-continuous resource. Specifically, the first portion of resources includes multiple non-continuous groups of resources, and the resources within each group of resources are continuous. In this case, Option 1) the first channel can use all resources of the first portion of resources for transmission. Accordingly, the first device determines the TBS corresponding to the first channel based on the total number of resources of the first portion of resources. Option 2) the first channel can use a group of resources of the first portion of resources for transmission. Accordingly, the first device determines the TBS corresponding to the first channel based on the number of resources of a group of resources in the multiple groups of resources. Here, a group of resources in the multiple groups of resources can be determined, but is not limited to, in the following manner:

[0095] One group of resources among the multiple groups of resources is a group of resources with the largest number of resources among the multiple groups of resources; or

[0096] One of the plurality of resource groups is a group of resources with the smallest resource number among the plurality of resource groups; or

[0097] One of the plurality of resource groups is a group of resources with the largest resource number among the plurality of resource groups; or

[0098] One of the plurality of resource groups is the earliest resource group among the plurality of resource groups; or

[0099] The group of resources among the multiple groups of resources is the latest group of resources among the multiple groups of resources.

[0100] Here, one of the multiple groups of resources is the group with the largest number of resources in the multiple groups of resources, which can ensure that the first channel can use the group with the largest number of resources in the first part of resources for transmission, thereby improving resource utilization.

[0101] Here, one of the multiple groups of resources is the group of resources with the smallest resource number among the multiple groups of resources. This ensures that the first channel can be transmitted using the group of resources with the smallest resource number among the first portion of resources, thereby reducing transmission latency. The group of resources with the smallest resource number among the multiple groups of resources may be the first group of resources among the multiple groups of resources.

[0102] Here, one of the multiple groups of resources is the earliest group of resources in the multiple groups of resources, which can ensure that the first channel can use the earliest group of resources in the first part of resources for transmission, thereby reducing transmission delay. The earliest group of resources in the multiple groups of resources can be the first group of resources in the multiple groups of resources. Each group of resources in the multiple groups of resources has a temporal sequence, and the time of a group of resources can refer to the time of a resource in the group of resources (for example, the first resource).

[0103] In the embodiment of the present application, the first device determines the TBS corresponding to the first channel based on the quantity of resources in the first part of resources, including:

[0104] The first device determines the resource quantity of the first part of resources;

[0105] The first device determines a TBS corresponding to the first channel based on the resource quantity of the first part of resources.
