Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technologies, and for example, relates to a method for determining data transmission parameters, an indication method, a communication node, and a medium. Background Art
[0002] In wireless communication technologies, the Multimedia Broadcast Multicast Service (MBMS) transmission based on the Long Term Evolution (LTE) system has been further enhanced, which is specifically divided into two mechanisms: single-cell transmission and multi-cell transmission. Among them, multi-cell transmission means that multiple broadcast / multicast cells transmit the same specific service, so as to achieve combined reception at the receiving end. Multi-cell transmission introduces a Single Frequency Network (SFN) transmission mode in the access network, that is, a Multicast Broadcast Single Frequency Network (MBSFN) transmission mode, which is to synchronously transmit at the same frequency in multiple cells at the same time. Each cell within an MBSFN area uses a common scrambling code instead of a cell-specific scrambling code to provide the MBMS service. In this way, a User Equipment (UE) does not need to distinguish between the signal of its own cell and the signal of neighboring cells when receiving the MBMS signal. The MBMS signal of neighboring cells is like the multipath signal of its own cell at the UE receiver. Using this transmission mode can save frequency resources and improve spectrum utilization. Moreover, the diversity effect brought by this multi-cell co-frequency transmission can solve problems such as blind area coverage, and can enhance the reliability of reception and improve the coverage rate.
[0003] The MBMS transmission based on the LTE system will potentially be deployed on the working spectrum of traditional television broadcast systems (such as DVB-T2), and the traditional television broadcast systems have not completely withdrawn from the network. Therefore, it is necessary to consider the coexistence problem between the LTE-based MBMS transmission and traditional television broadcast systems. In addition, the performance of the MBMS transmission based on the LTE system will be severely damaged in the presence of multipath and fading channels. How to ensure the transmission performance of the MBSM service in multipath and fading channels is an important problem that needs to be solved in the process of standard evolution.

[0022] The present application will be described below with reference to the accompanying drawings and embodiments. The technical solutions in the present disclosure are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments.

Additionally, it should be noted that for the sake of description, only a part related to the present application rather than all the structures are shown in the drawings.
[0023] It should be noted that in the present disclosure, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

The "and / or" herein is only a description of the association relationship of the associated objects, indicating that three relationships may exist.

[0026] As in the background art, MBMS in a mobile communication system allows data to be sent from a single source to multiple receivers, effectively utilizing network resources to transmit the same content. This technology was first introduced in 3GPP R6 and was subsequently enhanced in the LTE system, known as eMBMS.
[0027] In the 5th-Generation Mobile Communication Technology (5G), the MBMS transmission based on the LTE system is further enhanced. Specifically, the MBMS in the LTE system adopts the Multicast-Broadcast Single-Frequency Network (MBSFN) transmission mode, that is, multiple base stations synchronously send the same content on the same time-frequency resource, so that the multiple signals received by the User Equipment (UE) can be regarded as multipath signals, thereby obtaining the multi-transmit diversity gain. The main feature of MBSFN is that all cells in the coverage area use the same physical resources and the same transmission parameters.
[0028] The MBMS transmission based on the LTE system will potentially be deployed on the working spectrum of the traditional television broadcast system (for example, DVB-T2), and the traditional television broadcast system has not completely withdrawn from the network. Therefore, it is necessary to consider the coexistence problem between the LTE-based MBMS transmission and the traditional television broadcast system.
[0029] In view of the above technical problems, the embodiments of the present disclosure provide a method for determining data transmission parameters. The idea is that: the first communication node determines the data transmission parameters, and the data transmission parameters include at least one of a silent pattern configuration parameter and a frequency-domain interleaving parameter; the first communication node receives the target service according to the data transmission parameters. In this way, it can enable the base station and the terminal to have a consistent understanding of the data transmission scheme of the target service, ensure that the base station and the terminal can have a definite processing flow and method when encountering some specific situations, so as to realize the co-frequency coexistence between different systems. And it can effectively ensure that the target information is correctly received, improve the reliability of the broadcast multicast service transmission, and further improve the transmission performance of the target service in a multipath and fading channel.
[0030] The mobile communication system provided by the embodiments of the present disclosure will be introduced in detail below with reference to the accompanying drawings of the specification.
[0031] In the embodiments of the present disclosure, the network architecture of a mobile communication system (including but not limited to 3G, 4G, 5G, and future mobile communication systems) may at least include a first communication node and a second communication node. It should be understood that, in this example, in the downlink, the first communication node may be a terminal-side device (such as including but not limited to a terminal), and the second communication node may be a network-side device (such as including but not limited to a base station). Of course, in the uplink, the second communication node may also be a terminal-side device, and the first communication node may also be a network-side device. In device-to-device communication between two communication nodes, both the first communication node and the second communication node may be base stations or terminals. For ease of description, the first communication node may be described as the first node, and the second communication node may be described as the second node.
[0032] Exemplarily, taking the first node as a terminal and the second node as a base station as an example, Figure 1 is a schematic diagram of the network architecture of a mobile communication system provided by an embodiment of the present application. As Figure 1 shown, the mobile communication network includes a terminal 110 and a base station 120.
[0033] In some embodiments, the terminal 110 may be a device with wireless transceiver functions, which can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on water (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, a satellite, etc.). The terminal may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as a user, a UE, an access terminal, a UE unit, a UE station, a mobile station, a mobile unit, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE device, etc., and the embodiments of the present disclosure do not limit this.
[0034] In some embodiments, the terminal 110 includes a terminal supporting MBMS and a terminal not supporting MBMS. Exemplarily, the terminal supporting MBMS includes a terminal supporting eMBMS and a terminal supporting Further evolved Multimedia Broadcast Multicast Service (FeMBMS).
[0035] In some embodiments, the base station 120 is used to provide wireless access services for multiple terminals 110. Specifically, a base station provides a service coverage area (also referred to as a cell). The terminal 110 entering this area can communicate with the base station 120 through wireless signals to receive the wireless access services provided by the base station 120.
[0036] In some embodiments, the base station 120 can be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, remote radio heads, reconfigurable intelligent surfaces (RIS), routers, Wireless Fidelity (WIFI) devices, and other network-side devices.
[0037] In some embodiments, the base station 120 includes an MBMS cell (or referred to as an MBMS dedicated cell). In some embodiments, performing broadcast transmission within the MBMS dedicated cell is a broadcast transmission mode defined based on the LTE system, which has high transmission efficiency and good compatibility with the LTE unicast system. In the MBMS dedicated cell, only MBMS transmission is performed, and non-MBMS services are not supported, that is, unicast traffic is not supported. For UEs that do not support Further evolved MBMS (FeMBMS), they are not supported to camp on these cells, and paging is not supported on the MBMS dedicated cell.
[0038] In some embodiments, the characteristics of the MBMS dedicated cell include:
[0039] The Multimedia Broadcast Multicast Traffic Channel (MTCH) and the Multimedia Broadcast Multicast Control Channel (MCCH) are mapped onto the Multicast Channel (MCH) and transmitted in the form of MBSFN (Multicast Broadcast Single Frequency Network);
[0040] The system information required for MBMS received from the MBMS dedicated cell is broadcast on non-MBSFN subframes. The system information change notification and the emergency warning system (such as ETWS and CMAS, etc.) notifications are provided through the layer-1 (L1) signals on non-MBSFN subframes;
[0041] The non-MBSFN subframe with a control region, also known as the Cell Acquisition Subframes (CAS), is used to capture signals (such as the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), etc.), the Physical Downlink Control Channel (PDCCH), and the system information on the Physical Broadcast Channel (PBCH) and the Physical Downlink Shared Channel (PDSCH). Figure 2 FIG. is a schematic diagram of capturing signals through a cell acquisition subframe provided for an embodiment of the present application, such as Figure 2 shown, the CAS is transmitted with a period of 40 ms and uses subframes with a subcarrier spacing △f = 15 kHz. And it fixedly occupies the first subframe every 40 ms.
[0042] The PBCH of the MBMS dedicated cell is initialized with a random sequence different from that of the PBCH of the MBMS / unicast hybrid cell, which can prevent UEs that do not support FeMBMS from camping on this cell. In the MBMS dedicated cell, only the system information related to receiving the MBMS service is broadcast. The MIB-MBMS (Master Information Block-MBMS) and SIB1-MBMS (System Information Block Type1-MBMS) are used to replace the MIB and SIB1 in the conventional cell respectively. Among them, the MIB-MBMS defines the most critical physical layer information necessary for receiving further system information on the MBMS dedicated cell; the SIB1-MBMS contains the information related to receiving the MBMS service and defines the scheduling of other system information blocks on the MBMS dedicated cell.
[0043] In some embodiments, a cell may belong to multiple MBSFN Areas, each MBSFN Area corresponding to an MCCH. The MCCH message carries the set of MBSFN Subframes corresponding to this MCCH, as well as a list of physical multicast channel configurations (pmch-config); each pmch-config in it contains the set of MBSFN Subframes corresponding to this PMCH, and the PMCHs in the pmch-config list sequentially occupy a certain number of MBSFN Subframes; each pmch-config may contain one or more MTCHs and corresponds to a medium access control (MAC) control element (CE) of a multicast channel scheduling information (MCH Scheduling Information, MSI), which occupies the first MBSFN Subframe corresponding to this pmch-config. Figure 3 Schematic diagram of an MSI MAC CE provided by an embodiment of this application, as Figure 3As shown, the logical channel identifier (LCID) corresponds one-to-one with MTCH, and stop MTCH x is used to indicate the end subframe index of MTCH x corresponding to LCID x. The correspondence between MTCH x and LCID x is pre-configured. In some embodiments, MCCH and MSI are transmitted in configurable periods. Schematically, the set of configurable periods includes at least one of the following values: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 radio frames (or milliseconds), etc.
[0044] Figure 4 The figure is a flowchart of a method for determining data transmission parameters provided by an embodiment of the present application. This method can be applied to a first communication node. The first communication node can be a user-side node or a receiving end of target service data, such as a UE. The second communication node can be a network-side node or a sending end of service data, such as a base station. As Figure 4 shown, the method provided by this embodiment includes step 210 and step 220.
[0045] In step 210, the first communication node determines data transmission parameters, which include at least one of a silent pattern configuration parameter and a frequency-domain interleaving parameter.
[0046] In step 220, the first communication node receives the target service according to the data transmission parameters.
[0047] In this embodiment, the first communication node determines the data transmission parameters, including: the first communication node receives the silent pattern configuration parameter sent by the second communication node; wherein, the silent pattern configuration parameter includes at least one of the following parameters: the first parameter n, the second parameter m; wherein, the first parameter n is used to determine the period of the silent pattern; the second parameter m is used to determine the length of the time-domain resource allowed to transmit the target service within the period of the silent pattern.
[0048] In one embodiment, the period of the silent pattern is defined as A×n; the length of the time-domain resource allowed to transmit the target service within the period of the silent pattern is defined as B×m; wherein, A and B are predefined values respectively, and satisfy at least one of the following conditions: B = A / 4, or, B = A.
[0049] In one embodiment, when the value of A is 16 radio frames or 160 milliseconds, the value of B is equal to A / 4; or, when the value of A is 4 radio frames or 40 milliseconds, the value of B is equal to A.
[0050] In one embodiment, the value of the first parameter n is configured based on a first configuration set, and the first configuration set is defined as one of the following: {2, 4, 8, 16}, or {8, 16, 32, 64}.
[0051] In one embodiment, the value of the second parameter m is determined based on a second configuration set, and the second configuration set is defined as at least one of the following: {4, 5, 6, 7}, {4, 5, 6, 7, 8,..., 15}, {4, 5, 6, 7, 8,..., 31}, {4, 5, 6, 7, 8,..., 63}, {4, 5, 6, 7, 8,..., 25}, {1, 2, 3, 4, 5, 6, 7}, {1, 2, 3, 4, 5, 6, 7, 8,..., 15}, {1, 2, 3, 4, 5, 6, 7, 8,..., 31}, {1, 2, 3, 4, 5, 6, 7, 8,..., 63}, {1, 2, 3, 4, 5, 6, 7, 8,..., 25}.
[0052] In one embodiment, a plurality of second configuration sets are defined, and different second configuration sets correspond to different values of the first parameter n. The first communication node determines the value of the second parameter m based on the second configuration set corresponding to n.
[0053] In one embodiment, the value of the second parameter m is determined based on a second configuration set, and the second configuration set contains the value 4×n. When m is configured as 4×n, the time-domain resources within the period of the silent pattern can all be used to receive the target service.
[0054] In one embodiment, the value of the second parameter m is determined based on a second configuration set, and the second configuration set contains the value n. When m is configured as n, the time-domain resources within the period of the silent pattern can all be used to receive the target service.
[0055] In one embodiment, the method further includes: the first communication node determines the starting point of the time-domain resources allowed to transmit the target service within the period of the silent pattern. Wherein, the starting point of the time-domain resources is aligned with the period boundary of the silent pattern; or, the starting point of the time-domain resources is determined by a third parameter p, wherein the time-domain offset between the starting point of the time-domain resources and the boundary of the period of the silent pattern is equal to B×p, and p is a non-negative integer.
[0056] In one example, when at least one of the first parameter n and the second parameter m is not configured, the first communication node does not perform silence within the period of the current silent pattern, that is, all the time-domain resources within the period of the silent pattern can be used to receive the target service.
[0057] In one example, when at least one of the first parameter n and the second parameter m is not configured, the first communication node performs silence on all resources within the period of the current silence pattern, that is, all time-domain resources within the period of the silence pattern are not available for receiving the target service.
[0058] In one example, when at least one of the first parameter n and the second parameter m is configured with a specific value, the first communication node does not perform silence within the period of the current silence pattern, that is, all time-domain resources within the period of the silence pattern are available for receiving the target service.
[0059] In one example, when at least one of the first parameter n and the second parameter m is configured with a specific value, the first communication node performs silence on all resources within the period of the current silence pattern, that is, all time-domain resources within the period of the silence pattern are not available for receiving the target service.
[0060] In one embodiment, the first communication node obtains the value of at least one of the first parameter n and the second parameter m through the system information carried in the cell capture subframe.
[0061] In one embodiment, the values of the first parameter n and the second parameter m are obtained through a signaling or information unit. Among them, different configuration sets of the second parameter m are defined for different values of the first parameter n in the signaling or information unit.
[0062] In one embodiment, the frequency-domain interleaving parameter includes the number of frequency-domain interleaving columns.
[0063] In one embodiment, the number of frequency-domain interleaving columns is determined by a preset multiple of the number of code blocks on the target service unit symbol.
[0064] In one embodiment, the number of frequency-domain interleaving columns is where #CBs is the number of code blocks (CBs) included in one transport block (TB), N symb is the number of symbols of the target service, and the value of M is related to at least one of the following: the number of symbols of the target service, the number of code blocks included in one transport block.
[0065] In one embodiment, the value of M is defined as M = N symb or, where gcd(x, y) is an operation to calculate the greatest common divisor of x and y.
[0066] In one embodiment, when there are multiple candidate values of M, the first communication node determines the value of the number of frequency-domain interleaving columns M according to the indication of the higher-layer signaling of the second communication node.
[0067] In one embodiment, a first communication node receives a target service according to data transmission parameters, including: the first communication node receives the target service within a time domain resource that allows the transmission of the target service during a silent period determined according to silent pattern configuration parameters; or, the first communication node receives the target service according to a frequency domain interleaver configuration.
[0068] In one embodiment, the first communication node is a user-side node, and the second communication node is a network-side node.
[0069] Figure 5 The flowchart of a method for indicating data transmission parameters provided by an embodiment of the present application can be applied to a second communication node, and the second communication node can be a base station or a sender of service data. As Figure 5 shown, the method provided in this embodiment includes step 310 and step 320.
[0070] In step 310, data transmission parameters are sent to the first communication node, and the data transmission parameters include at least one of silent pattern configuration parameters and frequency domain interleaving parameters;
[0071] In step 320, the second communication node transmits the target service according to the data transmission parameters.
[0072] The following uses some embodiments to exemplarily illustrate the method for determining data transmission parameters of the present application.
[0073] In one embodiment, a method for determining data transmission parameters is described. The data transmission parameters include silent pattern configuration parameters, and the method specifically involves a first node determining an information transmission silent pattern through at least one of the following parameters: a first parameter n, a second parameter m, a third parameter A, and a fourth parameter B.
[0074] In one example, Figure 6 The schematic diagram of a data transmission silent pattern provided by an embodiment of the present application, as Figure 6As shown, the first parameter n and the third parameter A are used by the first node to determine the period of the silent pattern, and the period is configured in units of radio frames or milliseconds. In one example, the period is defined as A×n radio frames or milliseconds. Specifically, A is a predefined or preconfigured integer. For example, A = 16 or 4 radio frames (or A = 160 or 40 milliseconds); n is a configurable positive integer. In one example, the configuration set of n includes one or more of the following values: 2, 4, 8, 16. In another example, the configuration set of n includes one or more of the following values: 8, 16, 32, 64. In one example, the value of n is indicated within the configuration set by 2-bit indication information, that is, different values of the indication information correspond to different values of the parameter n. For example, when the indication information is set to 00, the value of n corresponds to the first value in the configuration set (i.e., 2 or 8); when the indication information is set to 01, the value of n corresponds to the second value in the configuration set (i.e., 4 or 16); when the indication information is set to 10, the value of n corresponds to the third value in the configuration set (i.e., 8 or 32); when the indication information is set to 11, the value of n corresponds to the fourth value in the configuration set (i.e., 16 or 64). In another example, the configuration set includes 8 values, and the value of n is indicated within the configuration set by 3-bit indication information.
[0075] In one example, as Figure 6As shown, the second parameter m and the fourth parameter B are used by the first node to determine the length of the time-domain resources that can be used to transmit information within the period of the silent pattern. Except for the time-domain resources that can be used to transmit information within the period of the silent pattern, the remaining resources are silent time-domain resources (for example, they can be occupied by other systems). In one example, the length of the time-domain resources is defined as B×m wireless frames. In one example, B is a predefined or preconfigured positive integer and satisfies B = A / 4. For example, A = 16 wireless frames (or 160 milliseconds) and B = 4 wireless frames (or 40 milliseconds); in one example, m is a configurable positive integer, and the configuration set of m contains one or more of the following values: {1, 2, 3, 4, 5, 6, 7, 8,..., 63, 64}. In one example, the configuration set of m is defined as at least one of the following: {4, 5, 6, 7}, {4, 5, 6, 7, 8,..., 15}, {4, 5, 6, 7, 8,..., 31}, {4, 5, 6, 7, 8,..., 63}, {4, 5, 6, 7, 8,..., 25}, {1, 2, 3, 4, 5, 6, 7}, {1, 2, 3, 4, 5, 6, 7, 8,..., 15}, {1, 2, 3, 4, 5, 6, 7, 8,..., 31}, {1, 2, 3, 4, 5, 6, 7, 8,..., 63}, {1, 2, 3, 4, 5, 6, 7, 8,..., 25}. In one example, multiple configuration sets of m are defined, and different configuration sets correspond to different values of n. For example, when n = 2, the configuration set of m is {4, 5, 6, 7} or {4, 5, 6, 7, 8}. When n = 4, the configuration set of m is {4, 5, 6, 7, 8,..., 15} or {4, 5, 6, 7, 8,..., 16}. When n = 8, the configuration set of m is {4, 5, 6, 7, 8,..., 31} or {4, 5, 6, 7, 8,..., 32}. When n = 16, the configuration set of m is {4, 5, 6, 7, 8,..., 63} or {4, 5, 6, 7, 8,..., 64}. In another example, the configuration set of m contains 4×n, and when m is configured as 4×n, all the time-domain resources within the silent period can be used to send information.
[0076] In another example, B is a predefined or preconfigured positive integer, and B = A. For example, B = A = 4 radio frames (or 40 milliseconds); in one example, m is a configurable positive integer, and the configuration set of m contains one or more of the following values: {1, 2, 3, 4, 5, 6, 7, 8,..., 63, 64}. In one example, the configuration set of m is defined as at least one of the following: {4, 5, 6, 7}, {4, 5, 6, 7, 8,..., 15}, {4, 5, 6, 7, 8,..., 31}, {4, 5, 6, 7, 8,..., 63}, {4, 5, 6, 7, 8,..., 25}, {1, 2, 3, 4, 5, 6, 7}, {1, 2, 3, 4, 5, 6, 7, 8,..., 15}, {1, 2, 3, 4, 5, 6, 7, 8,..., 31}, {1, 2, 3, 4, 5, 6, 7, 8,..., 63}, {1, 2, 3, 4, 5, 6, 7, 8,..., 25}. In one example, multiple configuration sets of m are defined, and different configuration sets correspond to different values of n. For example, when n = 8, the configuration set of m is {4, 5, 6, 7} or {4, 5, 6, 7, 8}. When n = 16, the configuration set of m is {4, 5, 6, 7, 8,..., 15} or {4, 5, 6, 7, 8,..., 16}. When n = 32, the configuration set of m is {4, 5, 6, 7, 8,..., 31} or {4, 5, 6, 7, 8,..., 32}. When n = 64, the configuration set of m is {4, 5, 6, 7, 8,..., 63} or {4, 5, 6, 7, 8,..., 64}. In another example, the configuration set of m contains n, and when m is configured as n, all time-domain resources within the silent period can be used for transmitting information.
[0077] In one example, the starting point of the time-domain resources for transmitting information is aligned with the periodic boundary of the information transmission silent pattern. In another example, the starting point of the time-domain resources for transmitting information is configured by a time-domain offset parameter p, and the time-domain offset refers to the time offset between the starting point of the time-domain resources and the periodic boundary of the information transmission silent pattern. In one example, the time-domain offset is equal to B × p, where p is a non-negative integer.
[0078] In one example, when at least one of the parameters n and m is not configured, the first communication node does not perform silence within the period of the current silent pattern, that is, all time-domain resources within the period of the silent pattern can be used for receiving the target service.
[0079] In one example, when at least one of the parameters n and m is not configured, the first communication node performs silence on all resources within the period of the current silent pattern, that is, all time-domain resources within the period of the silent pattern cannot be used for receiving the target service.
[0080] In one example, when at least one of the parameters n and m is configured with a specific value, the first communication node does not perform muting during the period of the current muting pattern, that is, all time domain resources during the period of the muting pattern can be used for receiving the target service.
[0081] In one example, when at least one of the parameters n and m is configured with a specific value, the first communication node performs muting on all resources during the period of the current muting pattern, that is, all time domain resources during the period of the muting pattern are not available for receiving the target service.
[0082] In some examples, the values of the parameters n and m are configured through the system information (e.g., MIB - MBMS, or SIB1 - MBMS) carried in the cell acquisition subframes (CAS). The values of the parameters n and m can be configured through independent signaling or information elements.
[0083] In one example, when the values of the parameters n and m are configured through independent signaling or information elements, the configured values need to satisfy the following conditions: A×n≥B×m, or A×n>B×m. In one example, the first communication node does not expect A×n<B×m, or A×n≤B×m.
[0084] In one example, the configured parameter values need to satisfy the following conditions: A×n≥B×(m + p), or A×n>B×(m + p). In one example, the first communication node does not expect A×n<B×(m + p), or A×n≤B×(m + p).
[0085] In one example, the values of the parameters n and m remain consistent throughout the muting period; that is, the same configured muting pattern parameters are carried in all CASs during the muting period; in another example, the values of the parameters n and m can be configured with different values in different muting periods.
[0086] In one example, at least one of the parameters n and m can change its value during the muting period. For example, the parameter configuration can be changed to other values starting from a specific boundary during the muting period, for example, starting from the radio frame where SFN mod 16 = 0, at least one of the values of the parameters n and m can be modified.
[0087] In one example, the values of the parameters n and m are configured through a combined signaling or information element.
[0088] Specifically, the signaling or information element (e.g., the period and available duration of the muting pattern, mutingPatternPeriodicityAndDuration) is defined as a structure:
[0089]
[0090] In the above examples, the different values of n and the corresponding value sets of m are only examples, and the defined signaling structure is also applicable to other values of n and the corresponding value sets of m.
[0091] In some examples, the performance of the target service transmission in the presence of multipath and fading channels will be severely impaired. How to ensure the transmission performance of the MBSM service in multipath and fading channels is an important issue to be solved in the process of standard evolution. To address the above technical problems, the embodiments of the present disclosure provide a frequency-domain interleaved data transmission method. The idea is as follows: For the data within the same symbol, interleaving processing is performed by writing column by column and reading row by row, so as to scatter the data of different code blocks as much as possible, thereby improving the reliability of the broadcast and multicast service transmission and further enhancing the transmission performance of the target service in multipath and fading channels.
[0092] Exemplarily, the above symbol may be Orthogonal Frequency Division Multiplexing (OFDM). The above data may be modulation symbols mapped on Resource Elements (REs).
[0093] It can be understood that frequency-domain interleaving refers to, in the frequency domain, based on a row-column interleaver, writing the REs from a single OFDM symbol into the interleaving memory column by column and reading them out row by row. This interleaving can utilize frequency diversity to improve the anti-fading ability of the signal at different frequencies.
[0094] In some embodiments, the frequency-domain interleaving parameters may be determined based on predefined parameters or configured based on signaling.
[0095] In some embodiments, the frequency-domain interleaving parameters at least include the number of frequency-domain interleaving columns.
[0096] Exemplarily, the number of frequency-domain interleaving columns X is predefined as a determined value. For example, X = 32.
[0097] Exemplarily, the number of frequency-domain interleaving columns is related to the number of code blocks of a transmission block of the target service and the number of symbols of the target service.
[0098] Exemplarily, the number of frequency-domain interleaving columns is determined by a preset multiple of the number of code blocks per unit symbol of the target service. For example, the number of frequency-domain interleaving columns is where #CBs is the number of code blocks (CBs) included in a transmission block (TB), N symb is the number of symbols of the target service, and the value of M is related to at least one of the following: the number of symbols of the target service, the number of code blocks of a transmission block.
[0099] Exemplarily, the value of M is M = N symb , then the number of frequency-domain interleaved columns is
[0100] Exemplarily, the value of M is then the number of frequency-domain interleaved columns is where gcd(x, y) is an operation to calculate the greatest common divisor of x and y.
[0101] Exemplarily, when there are multiple candidate values of M, the first communication node determines the value of the number of frequency-domain interleaved columns m according to the high-layer signaling indication or rule of the second communication node. Exemplarily, the high-layer signaling includes at least one of the following: Media Access Control (MAC) layer signaling, Radio Resource Control (RRC) layer signaling. Exemplarily, the rule can be defined as: when N symb =#CBs, M = N symb ; when N symb ≠#CBs, Exemplarily, the rule can be defined as: according to whether #CBs is equal to gcd(#CBs, N symb ), determine different values of M; for example, when or #CBs = gcd(#CBs, N symb ), M takes the first value, for example M = N symb ; when or #CBs ≠ gcd(#CBs, N symb ), M takes the second value, for example
