Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data processing method and a communication device. Background Art

[0002] In the frame structure of a wireless communication system, a radio frame can include multiple subframes, and the length of each subframe is fixed. For example, in the long-term evolution (LTE) system of universal mobile communication technology, a radio frame includes 10 subframes, and the length of each subframe is 1ms.

[0003] The rapid development of Internet technology has spawned a large number of emerging services. When the channel used to transmit a certain service requires at least two consecutive subframes, and the number of consecutive subframes in a radio frame that can be used to transmit the service exceeds the number of consecutive subframes required by the channel to transmit the service, the terminal cannot determine the starting subframe of the consecutive subframes in the radio frame used to transmit the service. For example, if the channel used to transmit service 1 requires two consecutive subframes, and three consecutive subframes in the radio frame (subframes 0, 1, and 2) can be used to transmit service 1, the terminal cannot determine whether the starting subframe of the consecutive subframes used to transmit service 1 is subframe 0 or subframe 1.

[0053] In order to better understand a data processing method disclosed in an embodiment of the present application, the communication system to which the embodiment of the present application is applicable is first described below.

[0054] See Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system disclosed in an embodiment of the present application. Figure 1 As shown, the communication system includes a network device 101 and a terminal device 102 .

[0055] When at least two consecutive subframes are required to transmit a first channel, and the number of consecutive subframes that can be used to transmit the first channel in a radio frame is greater than the number of consecutive subframes required to actually transmit the first channel, the network device 101 may configure some or all subframes in a subframe set as subframes actually used to transmit the first channel, generate first information, and then send the first information to the terminal device 102. The subframe set may include multiple consecutive subframes in the same radio frame, and each subframe in the subframe set can theoretically be configured to transmit the first channel. The subframe set includes the first subframe, and the first information can be used to determine whether the first subframe is actually configured to transmit the first channel. After receiving the first information, the terminal device 102 may determine the starting subframe in the subframe set that is actually used to transmit the first channel based on the first information. Specifically, when the first subframe is the first subframe among the consecutive subframes in the subframe set, and the first subframe is actually configured to transmit the first channel, the terminal device may determine the first subframe as the starting subframe in the subframe set that is actually used to transmit the first channel.

[0056] Among them, the network device 101 in the embodiment of the present application is an access device that the terminal device 102 accesses to the communication system in a wireless manner. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present application can be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0057] The terminal device 102 in the embodiment of the present application is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal device.

[0058] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: long term evolution (LTE) system, fifth generation (5G) mobile communication system, new radio (NR) system, or other future new mobile communication systems. It should also be noted that, Figure 1 The fact that network device 101 sends the first information to a terminal device is for example only and does not limit the embodiments of the present application. In other feasible implementations, network device 101 may also send the first information to other terminal devices. That is, the data processing method disclosed in the embodiments of the present application may be applied not only to unicast communication systems but also to broadcast or multicast communication systems, or hybrid communication systems. In a hybrid communication system, both unicast data and broadcast or multicast data may be transmitted.

[0059] Among them, the hybrid communication system can be a multimedia broadcast multicast service (MBMS) / unicast hybrid communication system or a further enhanced multimedia broadcast multicast service (FeMBMS) / unicast hybrid communication system. In the MBMS / unicast hybrid communication system, both MBMS services and unicast services (such as unicast data information or unicast control information) can be transmitted. In the FeMBMS / unicast hybrid communication system, both MBMS services and unicast services can be transmitted. The FeMBMS / unicast hybrid communication system is a special MBMS / unicast hybrid communication system and needs to meet at least one of the following two conditions: first, subframe 4 and / or subframe 9 in the radio frame in the system are configured as multimedia broadcast multicast service single frequency network (MBSFN) subframes; second, there are subframes in the radio frame in the system that do not contain a unicast control area. Among them, the MBSFN subframe is a subframe used to transmit MBMS services. The MBSFN subframe can be divided into an MBSFN area and a non-MBSFN area. The MBSFN area can be a transmission resource for transmitting a physical multicast channel (PMCH) in an MBSFN subframe. The non-MBSFN area can also be called a unicast control area. The non-MBSFN area can be a transmission resource for transmitting non-PMCH. It should be noted that the size of the non-MBSFN area in the MBSFN subframe can be 0, that is, all transmission resources of the MBSFN subframe can be used to transmit PMCH. The transmission resources involved in the embodiments of the present application may include one or more of time domain resources, frequency domain resources, and code channel resources, such as orthogonal frequency division multiplexing (OFDM) symbols.

[0060] In an embodiment of the present application, the first channel may be a physical channel, specifically, the first channel may be a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH) or a PMCH. PDSCH may be used to carry downlink service data, etc.; PDCCH may be used to carry downlink scheduling information (such as channel allocation and downlink control information (DCI)); PMCH may be used to transmit MBMS service data. MBMS services may use MBSFN to jointly send MBMS signals on the same time domain, frequency domain and spatial domain resources through multiple synchronized cells, and then naturally form a merger of multiple cell signals in the air. It should be noted that the aforementioned non-PMCH may be PDSCH or PDCCH.

[0061] It can be understood that the communication system described in the embodiment of the present application is for the purpose of more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0062] The data processing method and communication device provided in this application are described in detail below with reference to the accompanying drawings.

[0063] See Figure 2 , Figure 2 This is a flow chart of a data processing method provided by an embodiment of the present application. The execution subjects of steps 201 and 202 are network devices, or chips in network devices, and the execution subject of step 203 is terminal devices, or chips in terminal devices. The following description will be made by taking network devices and terminal devices as the execution subjects of the data processing method as an example. Figure 2 As shown, the method may include but is not limited to the following steps:

[0064] Step S201: The network device generates first information, which is used to determine whether the first subframe is used to transmit the first channel. Transmitting the first channel requires at least two consecutive subframes. The first subframe is included in a subframe set, which includes multiple consecutive subframes in the same wireless frame.

[0065] In an embodiment of the present application, at least two consecutive subframes in a radio frame are required to transmit the first channel, some or all subframes in a radio frame can be configured to transmit the first channel, and all subframes in a subframe set can be configured to transmit the first channel. Specifically, the network device can configure all subframes in the subframe set to transmit the first channel. Optionally, the network device can configure only some consecutive subframes in the subframe set to transmit the first channel. For example, a radio frame includes 10 subframes, and the 10 subframes are numbered from 0 to 9, and only subframes 1 to 4 in the radio frame can be configured to transmit the first channel, and when two consecutive subframes are required to transmit the first channel, the subframe set may include subframes 1 to 2, subframes 2 to 3, subframes 3 to 4, subframes 1 to 3, subframes 2 to 4, or subframes 1 to 4 in the radio frame. When the subframe set includes two consecutive subframes (such as subframes 1 to 2, subframes 2 to 3, or subframes 3 to 4 in the radio frame), the network device may actually configure both of the two consecutive subframes to be used for transmitting the first channel. When the subframe set includes three or four consecutive subframes (such as subframes 1 to 3, subframes 2 to 4, or subframes 1 to 4 in the radio frame), the network device may actually configure two consecutive subframes of the three or four consecutive subframes to be used for transmitting the first channel, and the subframes in the subframe set that are not configured to transmit the first channel may be used to transmit other channels.

[0066] A radio frame may correspond to one or more subframe sets, each of which includes multiple consecutive subframes in the radio frame. It should be noted that different subframe sets may include different subframes. For example, if only subframes 1 to 4 in a radio frame can be configured to transmit the first channel, and two consecutive subframes are required to transmit the first channel, the radio frame may correspond to two subframe sets. The first subframe set may include subframes 1 to 2 in the radio frame, and the second subframe set may include subframes 3 to 4 in the radio frame. For another example, subframes 1 to 4 and subframes 6 to 9 in a wireless frame may be configured for transmitting a first channel, and when two consecutive subframes are required to transmit the first channel, the wireless frame may correspond to two subframe sets, the first subframe set may include at least two consecutive subframes among subframes 1 to 4 (such as subframes 1 to 2, subframes 2 to 3, subframes 3 to 4, subframes 1 to 3, subframes 2 to 4, or subframes 1 to 4); the second subframe set may include at least two consecutive subframes among subframes 6 to 9 (such as subframes 6 to 7, subframes 7 to 8, subframes 8 to 9, subframes 6 to 8, subframes 7 to 9, or subframes 6 to 9).

[0067] In an embodiment of the present application, the subframe configured for transmitting the first channel may be a second subframe, that is, if a subframe is configured as a second subframe, the subframe is actually used to transmit the first channel. In theory, each subframe in the subframe set can be configured as a second subframe, that is, each subframe in the subframe set can theoretically be used to transmit the first channel, but in actual circumstances, the subframes in the subframe set can also be configured as non-second subframes, that is, the subframes in the subframe set can also be used to transmit channels other than the first channel. In an embodiment of the present application, the subframes in the subframe set can be configured as either a second subframe or a non-second subframe, and only when a subframe in the subframe set is configured as a second subframe, the subframe is actually used to transmit the first channel. The subframe set may include multiple consecutive subframes, and the multiple consecutive subframes may include the first subframe. It should be noted that multiple consecutive subframes refer to multiple subframes with consecutive sequence numbers in the same wireless frame. The first subframe may be the first subframe of multiple consecutive subframes in the subframe set. For example, if the subframe set includes subframes No. 1 to No. 4, the first subframe may be subframe No. 1.

[0068] After completing the configuration of the subframes in the subframe set, the network device may generate first information according to the configuration situation. The first information may be used to determine whether the first subframe is actually used to transmit the first channel, that is, the first information may be used to determine whether the first subframe is actually configured as the second subframe. It should be noted that the first information may be used to directly indicate or indirectly indicate whether the first subframe is actually used to transmit the first channel. In one implementation, the network device may also generate the first information before completing the configuration of the subframes in the subframe set. Specifically, the network device may generate the first information after determining the configuration scheme of the subframes in the subframe set, but before completing the configuration. The configuration scheme of the subframes in the subframe set may indicate whether each subframe in the subframe set is actually configured as a second subframe or a non-second subframe, that is, the configuration scheme of the subframes in the subframe set may indicate whether each subframe in the subframe set is actually used to transmit the first channel. It should be noted that, in the embodiment of the present application, describing a subframe as being configured as the second subframe is equivalent to the subframe being configured for transmitting the first channel. Similarly, describing a subframe as being configured for transmitting the first channel is equivalent to the subframe being configured as the second subframe.

[0069] In one implementation, in addition to indicating whether the first subframe is configured as the second subframe, the first information may also indicate whether other subframes in the subframe set to which the first subframe belongs, except the first subframe, are configured as the second subframe. In one implementation, the first information may include a bitmap, which may be used to indicate whether each subframe in the subframe set is actually configured as the second subframe, and the value of each bit in the bitmap may indicate whether the corresponding subframe is actually configured as the second subframe. For example, when the value of the first bit in the bitmap is "1", it may indicate that the subframe corresponding to the first bit is configured as the second subframe; when the value of the second bit in the bitmap is "0", it may indicate that the subframe corresponding to the second bit is not configured as the second subframe, that is, the subframe corresponding to the second bit is configured as a non-second subframe. It should be noted that one bit in the bitmap corresponds to a subframe in the subframe set. For example, when the subframe set includes subframes 1 to 4 in the wireless frame, the bitmap may include 4 bits, where the value of the first bit is used to indicate whether subframe 1 is configured as the second subframe; similarly, the value of the second bit is used to indicate whether subframe 2 is configured as the second subframe; the value of the third bit is used to indicate whether subframe 3 is configured as the second subframe; and the value of the fourth bit is used to indicate whether subframe 4 is configured as the second subframe.

[0070] In an embodiment of the present application, the first information may be used to indicate the configuration of subframes in a subframe set corresponding to a radio frame. Optionally, the first information may also be used to indicate the configuration of subframes in subframe sets corresponding to two or more consecutive radio frames. For example, when a radio frame corresponds to multiple subframe sets (such as subframe set 1 and subframe set 2), the first information may specifically be used to indicate whether each subframe in subframe set 1 and subframe set 2 is configured as a second subframe. When the first information is used to indicate the configuration of subframes in multiple subframe sets corresponding to a radio frame, the bitmap in the first information may indicate the configuration of subframes in each subframe set in the radio frame. In the above example, if subframe set 1 and subframe set 2 both include 4 subframes, the bitmap in the first information may include 8 bits, the first 4 bits of the bitmap are used to indicate, in sequence, whether the 4 subframes in subframe set 1 are configured as second subframes; and the 5th to 8th bits of the bitmap are used to indicate, in sequence, whether the 4 subframes in subframe set 2 are configured as second subframes.

[0071] For another example, the first information is used to indicate the configuration of subframes in subframe sets corresponding to the first radio frame and the second radio frame, and the first radio frame corresponds to one subframe set (such as subframe set 1), and the second radio frame corresponds to two subframe sets (such as subframe set 2 and subframe set 3). In this case, the first information can be specifically used to indicate whether each subframe in subframe set 1, subframe set 2, and subframe set 3 is configured as the second subframe, wherein the first radio frame and the second radio frame are two consecutive subframes. When the first information is used to indicate the configuration of subframes in subframe sets corresponding to two or more consecutive radio frames, the bitmap in the first information can indicate the configuration of subframes in subframe sets corresponding to two or more consecutive radio frames. In the previous example, if subframe set 1, subframe set 2 and subframe set 3 all include 4 subframes, the bitmap in the first information may include 12 bits, and the first 4 bits in the bitmap are used to indicate whether the 4 subframes in subframe set 1 are configured as second subframes; the 5th bit to the 8th bit in the bitmap are used to indicate whether the 4 subframes in subframe set 2 are configured as second subframes; the 9th bit to the 12th bit in the bitmap are used to indicate whether the 4 subframes in subframe set 3 are configured as second subframes.

[0072] In one implementation, the first channel may be PMCH or other channels, the subframe transmitting the first channel (i.e., the second subframe) may be an MBSFN subframe or other types of subframes, and the aforementioned wireless frame may be a wireless frequency division duplex (FDD) frame or a wireless time division duplex (TDD) frame.

[0073] It should be noted that the subframes that can be configured as the second subframe in radio frames transmitted under different communication systems may be different. It should also be noted that the subframes that can be configured as the second subframe in different types of radio frames may be different. Specifically, when the first channel is PMCH and the second subframe is MBSFN, in an MBMS / unicast hybrid communication system, that is, the network device is a network device corresponding to an MBMS / unicast hybrid cell, and the radio frame is an FDD frame, subframes 0, 4, 5, and 9 in the radio frame cannot theoretically be used to transmit the first channel, that is, subframes 0, 4, 5, and 9 cannot theoretically be configured as MBSFN subframes. In other words, only subframes 1, 2, 3, 6, 7, and 8 in the radio frame can be configured as MBSFN subframes. In an MBMS / unicast hybrid communication system, when the radio frame is a TDD frame, subframes 0, 1, 2, 5, and 6 in the radio frame theoretically cannot be used to transmit the first channel. That is, subframes 0, 1, 2, 5, and 6 theoretically cannot be configured as MBSFN subframes. In other words, only subframes 3, 4, 7, 8, and 9 in the radio frame can be configured as MBSFN subframes. In an FeMBMS / unicast hybrid communication system, when the network device is a network device corresponding to an FeMBMS / unicast hybrid cell and the radio frame is an FDD frame, subframes 0 and 5 in the radio frame theoretically cannot be used to transmit the first channel. That is, subframes 0 and 5 theoretically cannot be configured as MBSFN subframes. In other words, only subframes 1, 2, 3, 4, 6, 7, 8, and 9 in the radio frame can be configured as MBSFN subframes.

[0074] Optionally, in an MBMS / unicast hybrid communication system, when the radio frame is a TDD frame, subframe 6 in the TDD frame can be configured as a downlink subframe or a special subframe. When subframe 6 is configured as a downlink subframe, it can be specifically configured as an MBSFN subframe. In this case, subframes 3, 4, 6, 7, 8, and 9 in the TDD frame can be configured as MBSFN subframes. A special subframe can consist of three parts: a downlink pilot time slot (DwPTS), an uplink pilot time slot (UpPTS), and a guard period (GP). The DwPTS can transmit downlink reference signals and control information; the UpPTS can transmit some short random access channel (RACH) and sounding reference signal (SRS) information; and the GP is the guard interval between uplink and downlink.

[0075] In an MBMS / unicast hybrid communication system, when the radio frame is an FDD frame and the second subframe is an MBSFN subframe, only subframes 1 to 3 and 6 to 8 in the radio frame can be configured as MBSFN subframes. If two consecutive subframes are required to transmit the first channel, the radio frame can correspond to one or two subframe sets. When the radio frame corresponds to one subframe set, the subframe set can include subframes 1 and 2, subframes 2 and 3, subframes 6 and 7, subframes 7 and 8, subframes 1 to 3, or subframes 6 to 8. When the radio frame corresponds to two subframe sets, the first subframe set can include subframes 1 and 2, subframes 2 and 3, or subframes 1 to 3, and the second subframe set can include subframes 6 and 7, subframes 7 and 8, or subframes 6 to 8. If three consecutive subframes are required to transmit the first channel, the wireless frame may correspond to one or two subframe sets. When the wireless frame corresponds to one subframe set, the subframe set may include subframes 1 to 3 or subframes 6 to 8. When the wireless frame corresponds to two subframe sets, the first subframe set may include subframes 1 to 3, and the second subframe set may include subframes 6 to 8.

[0076] In a hybrid MBMS / unicast communication system, if the radio frame is a TDD frame and the second subframe is an MBSFN subframe, only subframes 3-4 and 7-9 in the radio frame can be configured as MBSFN subframes. If two consecutive subframes are required to transmit the first channel, the radio frame can correspond to one or two subframe sets. When the radio frame corresponds to one subframe set, the subframe set can include subframes 3 and 4, subframes 7 and 8, subframes 8 and 9, or subframes 7-9. When the radio frame corresponds to two subframe sets, the first subframe set can include subframes 3 and 4, and the second subframe set can include subframes 7 and 8, subframes 8 and 9, or subframes 7-9. If three consecutive subframes are required to transmit the first channel, the radio frame can correspond to one subframe set, which can include subframes 7-9.

[0077] In a FeMBMS / unicast hybrid communication system, when the radio frame is an FDD frame and the second subframe is an MBSFN subframe, only subframes 1 to 4 and 6 to 9 in the radio frame can be configured as MBSFN subframes. If two consecutive subframes are required to transmit the first channel, the radio frame can correspond to one, two, three, or four subframe sets. When the radio frame corresponds to one subframe set, the subframe set can include any two consecutive subframes, any three consecutive subframes, or any four consecutive subframes from subframes 1 to 4 and subframes 6 to 9. When the radio frame corresponds to two subframe sets, the first subframe set can include any two consecutive subframes, any three consecutive subframes, or any four consecutive subframes from subframes 1 to 4 and subframes 6 to 9, and the second subframe set can include any two consecutive subframes, any three consecutive subframes, or any four consecutive subframes from subframes 1 to 4 and subframes 6 to 9, excluding the first subframe set. The case where a radio frame corresponds to three subframe sets is similar to the case where a radio frame corresponds to two subframe sets and is not further described here. When a radio frame corresponds to four subframe sets, the first subframe set may include subframes 1 to 2, the second subframe set may include subframes 3 to 4, the third subframe set may include subframes 6 to 7, and the fourth subframe set may include subframes 8 to 9.

[0078] In an embodiment of the present application, a radio frame may correspond to one or more subframe sets, and each subframe set includes a first subframe. Specifically, when in an MBMS / unicast hybrid communication system, and the radio frame is an FDD frame. If the FDD frame corresponds to a subframe set, and the subframe set includes subframes 1 to 3, the first subframe may be subframe 1 in the FDD frame. If the FDD frame corresponds to a subframe set, and the subframe set includes subframes 6 to 8, the first subframe may be subframe 6 in the FDD frame. When the FDD frame corresponds to two subframe sets, and the first subframe set includes subframes 1 to 3, and the second subframe set includes subframes 6 to 8, the first subframe in the first subframe set may be subframe 1 in the FDD frame, and the first subframe in the second subframe set may be subframe 6 in the FDD frame.

[0079] Similarly, in a hybrid FeMBMS / unicast communication system, if the radio frame is an FDD frame, and the FDD frame corresponds to a subframe set that includes subframes 1 to 4, the first subframe may be subframe 1 of the FDD frame; if the FDD frame corresponds to a subframe set that includes subframes 6 to 9, the first subframe may be subframe 6 of the FDD frame. If the FDD frame corresponds to two subframe sets, with the first subframe set including subframes 1 to 4 and the second subframe set including subframes 6 to 9, the first subframe in the first subframe set may be subframe 1 of the FDD frame, and the first subframe in the second subframe set may be subframe 6 of the FDD frame.

[0080] Similarly, in an MBMS / unicast hybrid communication system, if the radio frame is a TDD frame, if the TDD frame corresponds to a subframe set that includes subframes 3 to 4, the first subframe may be subframe 3 of the TDD frame; if the TDD frame corresponds to a subframe set that includes subframes 7 to 9, the first subframe may be subframe 7 of the TDD frame; if the TDD frame corresponds to a subframe set that includes subframes 6 to 9, the first subframe may be subframe 6 of the TDD frame. If the TDD frame corresponds to two subframe sets, with the first subframe set including subframes 3 to 4 and the second subframe set including subframes 7 to 9, the first subframe in the first subframe set may be subframe 3 of the TDD frame, and the first subframe in the second subframe set may be subframe 7 of the TDD frame.

[0081] It should be noted that different subframe sets include different subframes, and different subframe sets do not include the same subframes. That is to say, when a wireless frame corresponds to multiple subframe sets, each subframe in the wireless frame exists in at most one subframe set and cannot exist in multiple subframe sets.

[0082] Step S202: The network device sends the first information to the terminal device.

[0083] Specifically, after the network device generates the first information, it can send the first information to the terminal device, so that the terminal device can determine the starting subframe in the subframe set for transmitting the first channel based on the first information. In one implementation, when the first channel is PMCH, the starting subframe in the subframe set for transmitting the first channel may refer to the starting subframe in the subframe set for transmitting a complete PMCH symbol. For example, if three consecutive subframes are required to transmit a complete PMCH symbol, the starting subframe may be the first subframe of the three consecutive subframes. It should be noted that one or more complete PMCH symbols can be transmitted in a radio frame, but the subframes included in a subframe set can transmit at most one complete PMCH symbol. In other words, one radio frame can include one or more starting subframes, and a subframe set can include at most one starting subframe.

[0084] In one implementation, the first information may be high-layer indication information, which may be information transmitted in a high-layer protocol layer. The high-layer protocol layer may refer to at least one protocol layer above the physical layer in the open system interconnection (OSI) model or other models. Specifically, the high-layer protocol layer may include, but is not limited to, one or more of a medium access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, a radio resource control (RRC) layer, and a non-access stratum (NAS).

[0085] Step S203: The terminal device determines a starting subframe for transmitting the first channel in the subframe set according to the first information.

[0086] Specifically, after receiving the first information from the network device, the terminal device can determine the starting subframe for transmitting the first channel in the subframe set based on the first information, thereby facilitating accurate reception of the first channel based on the starting subframe.

[0087] When the first subframe is the first subframe among all consecutive subframes included in the subframe set, and the first information determines that the first subframe is actually used to transmit the first channel, the terminal device can determine the first subframe as the starting subframe actually used to transmit the first channel in the subframe set to which the first subframe belongs; if the first information determines that the first subframe is not used to transmit the first channel, the terminal device can determine other subframes other than the first subframe in the subframe set to which the first subframe belongs as the starting subframes actually used to transmit the first channel in the subframe set to which the first subframe belongs, or the terminal device can determine that there is no starting subframe for transmitting the first channel in the subframe set to which the first subframe belongs.

[0088] In one implementation, both the subframe set and the first subframe may be agreed upon by a protocol. In one implementation, the first subframe may also be a subframe other than the first subframe in the subframe set. In one implementation, the first information may further include a subframe identifier, which is used to identify the first subframe. The terminal device may determine, based on the first information, whether the first subframe indicated by the subframe identifier is actually configured for transmitting the first channel.

[0089] In one implementation, after the terminal device determines the starting subframe, it can determine the subframe for actually transmitting the first channel based on the number of consecutive subframes required to transmit the first channel. For example, if three consecutive subframes are required to transmit the first channel, and the starting subframe is subframe No. 1, the terminal device can determine subframes No. 1 to No. 3 as the subframes for actually transmitting the first channel. In one implementation, after the terminal device determines the subframe for actually transmitting the first channel, it can receive the first channel on the time-frequency resources corresponding to the determined subframe for actually transmitting the first channel. In this way, the situation where the first channel cannot be received from the correct time-frequency resources when the starting subframe cannot be determined can be avoided, which is conducive to improving the accuracy and efficiency of receiving the first channel.

[0090] In one implementation, the requirement of two consecutive subframes for transmitting the first channel may indicate that all transmission resources corresponding to the two consecutive subframes are used to transmit the first channel, or may indicate that part of the transmission resources corresponding to the two consecutive subframes are used to transmit the first channel. When two consecutive subframes are required to transmit the first channel, and all transmission resources corresponding to the two consecutive subframes are used to transmit the first channel, the terminal device may receive the first channel starting from the starting position of the transmission resource corresponding to the starting subframe of the two consecutive subframes.

[0091] In one implementation, the subframe for transmitting the first channel (i.e., the second subframe) may include a first area and a non-first area, the first area may be the transmission resource for transmitting the first channel in the second subframe, and the non-first area may be the transmission resource not used for transmitting the first channel in the second subframe. It should be noted that the size of the non-first area in the second subframe may be 0, that is, all transmission resources of the second subframe may be used to transmit the first channel. When two consecutive subframes are required to transmit the first channel, and part of the transmission resources corresponding to the two consecutive subframes are all used to transmit the first channel, all the first areas in the two consecutive subframes are used to transmit the first channel, and accordingly, the terminal device may receive the first channel from the first area in the two consecutive subframes. It should be noted that the transmission of the first channel requires two consecutive subframes, and the terminal device receives the first channel from the first area in the two consecutive subframes is only for example and does not constitute a limitation on the embodiments of the present application. In other feasible implementations, when the transmission of the first channel requires three consecutive subframes or other numbers of consecutive subframes, the terminal device may receive the first channel from the first area in the three consecutive subframes (or other numbers of consecutive subframes). It should also be noted that the aforementioned first area can be one or more continuous OFDM symbols in the time domain of the second subframe, or it can be multiple non-continuous OFDM symbols. The aforementioned first area can be one or more continuous resources or multiple non-continuous resources in the frequency domain of the second subframe. Specifically, it can be one or more continuous resource blocks (RBs) or resource elements (REs), or it can be multiple non-continuous RBs or REs. When the first OFDM symbol in the first area in the starting subframe is the first OFDM symbol in the starting subframe, the terminal device can receive the first channel from the first OFDM symbol in the starting subframe; when the first OFDM symbol in the first area in the starting subframe is not the first OFDM symbol in the starting subframe, the terminal device can receive the first channel from the first OFDM symbol in the first area in the starting subframe, that is, the terminal device may not receive the first channel from the first OFDM symbol in the starting subframe. Among them, one RB can include multiple REs, and RE (also called resource element) is the smallest resource unit in LTE physical resources. One RE can represent one OFDM symbol in the time domain and one subcarrier in the frequency domain.

[0092] In one implementation, all OFDM symbols in a second subframe having a subcarrier spacing (SCS) of a preset value may be used to transmit the first channel. When the second subframe is an MBSFN subframe, all OFDM symbols in the MBSFN subframe having a subcarrier spacing of a preset value may be used to transmit the first channel. In one implementation, the preset value may include, but is not limited to, any one of 2.5 kHz and less than or equal to 0.417 kHz.

[0093] It should be noted that when the MBSFN subframe meets any one of the following conditions, it can indicate that all OFDM symbols in the subframe can be used to transmit the first channel: MBSFN subframe with a subcarrier spacing less than or equal to 0.417kHz; the cyclic prefix (CP) length of the OFDM symbol in the MBSFN subframe is greater than or equal to 300μs; the length of the OFDM symbol (or core OFDM symbol) that does not contain the CP in the MBSFN subframe is greater than or equal to 2.4ms; the length of the OFDM symbol in the MBSFN subframe is greater than or equal to 2.7ms; the fast Fourier transform (FFT) size corresponding to the 20MHz bandwidth is greater than or equal to 73728; the FFT size corresponding to the 10MHz bandwidth is greater than or equal to 36864.

[0094] In one implementation, when a wireless frame corresponds to a subframe set, and the first information is used to determine whether a subframe (i.e., the first subframe) is used to transmit the first channel, the first information may also include a first numerical value. When the first numerical value is m, it can indicate that the next m adjacent subframes of the first subframe are all configured as second subframes, and m can be an integer greater than or equal to 0. In this way, after receiving the first information, the terminal device can quickly determine which subframes in the wireless frame are used to transmit the first channel based on the first information. For example, when subframe No. 1 in the wireless frame is the first subframe, and subframe No. 1 is configured as the second subframe, the first numerical value is 1, and two consecutive second subframes are required to transmit the first channel, the terminal device can determine that subframes No. 1 and No. 2 in the wireless frame are used to transmit the first channel, and subframe No. 1 is the starting subframe. For another example, when subframe 1 in a wireless frame is the first subframe and subframe 1 is not configured as the second subframe, the first value is 2, and two consecutive second subframes are required to transmit the first channel, the terminal device can determine that subframes 2 and 3 in the wireless frame are used to transmit the first channel, and subframe 2 is the starting subframe. In this way, carrying fewer bits of information in the first information allows the terminal device to quickly determine the subframe and starting subframe for transmitting the first channel.

[0095] In one implementation, when a radio frame corresponds to multiple subframe sets, and the first information is used to determine whether the first subframe in each subframe set is used to transmit the first channel, the first information may further include multiple first values. Different first values ​​may correspond to first subframes in different subframe sets. When the first value is m, it may indicate that the next m subframes adjacent to the first subframe in the corresponding subframe set are all configured as second subframes, where m may be an integer greater than or equal to 0. For example, when a wireless frame corresponds to two subframe sets, subframe No. 1 in the first subframe set is the first subframe, and subframe No. 1 is configured as the second subframe, the first numerical value corresponding to the first subframe set is 1, subframe No. 6 in the second subframe set is the first subframe, and subframe No. 6 is not configured as the second subframe, the first numerical value corresponding to the second subframe set is 2, and two consecutive second subframes are required to transmit the first channel, the terminal device can determine that subframes No. 1 to 2 and subframes No. 7 to 8 in the wireless frame are all used to transmit the first channel, and subframe No. 1 is the starting subframe in the first subframe set for transmitting the first channel, and subframe No. 7 is the starting subframe in the second subframe set for transmitting the first channel.

[0096] By implementing the embodiments of the present application, the starting subframe for transmitting the first channel in the subframe set can be determined according to the first information, thereby facilitating improving the accuracy and efficiency of receiving the first channel.

[0097] See Figure 3a , Figure 3a This is a flow chart of another data processing method provided by an embodiment of the present application. The method describes in detail how the network device configures the starting subframe of the first channel, and how the terminal device specifically determines the starting subframe for transmitting the first channel in the subframe set based on the first information. Among them, the execution subject of steps 301 to 303 is the network device, or the chip in the network device, and the execution subject of step 304 is the terminal device, or the chip in the terminal device. The following description takes the network device and the terminal device as the execution subject of the data processing method as an example. The method may include but is not limited to the following steps:

[0098] Step S301: The network device configures the first subframe as the starting subframe in the subframe set for transmitting the first channel. Transmitting the first channel requires at least two consecutive subframes. The first subframe is included in the subframe set, and the subframe set includes multiple consecutive subframes in the same wireless frame.

[0099] Specifically, the network device may configure the first subframe as the starting subframe in the subframe set for transmitting the first channel. When n consecutive subframes are required to transmit the first channel, and the network device configures the first subframe as the starting subframe in the subframe set for transmitting the first channel, it indicates that the first subframe and the consecutive n-1 subframes adjacent to the first subframe are all used to transmit the first channel. Where n can be an integer greater than or equal to 2, configuring the first subframe as the starting subframe in the subframe set for transmitting the first channel is equivalent to configuring the first subframe as the second subframe.

[0100] In one implementation, if the network device does not configure the first subframe as the starting subframe for transmitting the first channel in the subframe set, the network device may configure the next subframe adjacent to the first subframe in the subframe set as the starting subframe for transmitting the first channel in the subframe set. Figure 3b As an example, the schematic diagram of the configuration scheme of subframes in the wireless frame shown in FIG. Figure 3b The small and medium squares represent a subframe of a radio frame. The numbers in the small squares represent the numbers of the corresponding subframes in the radio frame. The small squares filled with gray indicate that the subframe can theoretically be configured as the second subframe. The small squares filled with white indicate that the subframe cannot be configured as the second subframe. The small squares filled with gray and diagonal lines indicate that the subframe is actually configured as the second subframe. Figure 3b It can be seen that subframes 1 to 3 in the wireless frame can be configured as the second subframes (i.e., subframes 1 to 3 can be configured to transmit the first channel), and the subframe set corresponding to the wireless frame includes subframes 1 to 3. When the first subframe in the subframe set is subframe 1, and subframe 1 is actually configured as the second subframe, the network device can also configure subframe 2 as the second subframe, so that the first channel can be transmitted on subframes 1 and 2 later. At this time, the starting subframe for transmitting the first channel in the subframe set is subframe 1. When the first subframe in the subframe set is subframe 1, and subframe 1 is not configured as the second subframe, as Figure 3c As shown, the network device can configure subframes 2 and 3 as the second subframe, so that the first channel can be transmitted subsequently on subframes 2 and 3. At this time, the starting subframe for transmitting the first channel in the subframe set is subframe 2.

[0101] In one implementation, if the network device does not configure the first subframe and the next subframe adjacent to the first subframe as the starting subframes for transmitting the first channel in the subframe set, and the number of subframes in the subframe set other than the first subframe and the next subframe adjacent to the first subframe is greater than or equal to the number of consecutive subframes required to transmit the first channel, the network device may configure the second subframe after the first subframe as the starting subframe in the subframe set for transmitting the first channel; if the number of subframes in the subframe set other than the first subframe and the next subframe adjacent to the first subframe is less than the number of consecutive subframes required to transmit the first channel, then there is no starting subframe for transmitting the first channel in the subframe set, that is, all subframes in the subframe set are not actually used to transmit the first channel.

[0102] Step S302: The network device generates first information, where the first information determines that the first subframe is used to transmit the first channel.

[0103] In an embodiment of the present application, a network device may generate first information based on whether the first subframe is configured as a starting subframe in a subframe set for transmitting a first channel, and the first information is used to determine whether the first subframe is used to transmit the first channel. Specifically, if the network device configures the first subframe as a starting subframe in a subframe set for transmitting the first channel, the first information generated by the network device may be used to determine that the first subframe is used to transmit the first channel; if the network device does not configure the first subframe as a starting subframe in a subframe set for transmitting the first channel, the first information generated by the network device may be used to determine that the first subframe is not used to transmit the first channel.

[0104] Step S303: The network device sends the first information to the terminal device.

[0105] It should be noted that the execution process of step S303 can be found in Figure 2 The specific description of step S202 is omitted here.

[0106] Step S304: The terminal device determines the aforementioned first subframe as the starting subframe in the subframe set for transmitting the first channel.

[0107] In an embodiment of the present application, after receiving the first information from the network device, the terminal device can determine the starting subframe in the subframe set for transmitting the first channel based on the first information, thereby facilitating accurate reception of the first channel based on the starting subframe. Specifically, if the first information determines that the first subframe is used to transmit the first channel, the terminal device can determine the first subframe as the starting subframe in the subframe set for transmitting the first channel; if the first information determines that the first subframe is not used to transmit the first channel, the terminal device can determine the next subframe in the subframe set adjacent to the first subframe as the starting subframe in the subframe set for transmitting the first channel.

[0108] In one implementation, in addition to determining whether the first subframe is used to transmit the first channel, the first information can also be used to indicate whether other subframes other than the first subframe in the subframe set to which the first subframe belongs are used to transmit the first channel. When n consecutive subframes are required to transmit the first channel, if the terminal device determines through the first information that the n consecutive subframes starting with the first subframe are all configured to transmit the first channel, the terminal device can determine the first subframe as the starting subframe for transmitting the first channel in the subframe set to which the first subframe belongs. If the terminal device determines through the first information that the first subframe is not used to transmit the first channel, the terminal device can determine through the first information whether the n consecutive subframes starting with the next subframe adjacent to the first subframe are all configured to transmit the first channel. If the n consecutive subframes starting with the next subframe adjacent to the first subframe are all configured to transmit the first channel, the terminal device can determine the next subframe adjacent to the first subframe as the starting subframe for transmitting the first channel in the subframe set to which the first subframe belongs. If the next subframe adjacent to the first subframe is not configured for transmitting the first channel, the terminal device can determine through the first information whether n consecutive subframes starting with the second subframe after the first subframe are all configured for transmitting the first channel. If n consecutive subframes starting with the second subframe after the first subframe are all configured for transmitting the first channel, the second subframe after the first subframe is determined as the starting subframe for transmitting the first channel in the subframe set to which the first subframe belongs. Until the number of subframes in the subframe set to which the first subframe belongs, except for the subframes that have been determined not to be used for transmitting the first channel, is less than n, the terminal device can determine that there is no starting subframe for transmitting the first channel in the subframe set. Wherein, n can be an integer greater than or equal to 2. In one implementation, the terminal device can determine whether each subframe in the subframe set is configured for transmitting the first channel through the bitmap in the first information.

[0109] By implementing the embodiments of the present application, if the first information determines that the first subframe is used to transmit the first channel, the terminal device can determine the first subframe as the starting subframe in the subframe set for transmitting the first channel; if the first information determines that the first subframe is not used to transmit the first channel, the terminal device can determine the next subframe adjacent to the first subframe in the subframe set as the starting subframe in the subframe set for transmitting the first channel. In this way, the accuracy and efficiency of receiving the first channel are improved.

[0110] See Figure 4a , Figure 4aThis is a flow chart of another data processing method provided by an embodiment of the present application. The method details how the network device configures the starting subframe of the first channel when one wireless frame corresponds to multiple subframe sets, and how the terminal device determines the starting subframe for transmitting the first channel in each subframe set based on the first information. Among them, the execution subject of steps 401 and 402 is the network device, or the chip in the network device, and the execution subject of step 403 is the terminal device, or the chip in the terminal device. The following is an example of the execution subject of the data processing method using the network device and the terminal device. The method may include but is not limited to the following steps:

[0111] Step S401: The network device generates first information, which is used to determine whether the first subframe is used to transmit the first channel. Transmitting the first channel requires at least two consecutive subframes. The number of first subframes is multiple, and the number of subframe sets is multiple. The first subframes correspond to the subframe sets one by one. Each first subframe is included in the corresponding subframe set. The subframe set includes multiple consecutive subframes in the same wireless frame.

[0112] In an embodiment of the present application, a radio frame may correspond to one or more subframe sets, each subframe set contains a first subframe, and the first subframes in different subframe sets are different. Taking one radio frame corresponding to two subframe sets as an example, if the subframes in the radio frame that can theoretically be used to transmit the first channel include subframes 1 to 3 and subframes 6 to 8, then the first subframe set corresponding to the radio frame may include subframes 1 to 3, and the second subframe set corresponding to the radio frame may include subframes 6 to 8. Among them, the first subframe in the first subframe set may be subframe 1, and the first subframe in the second subframe set may be subframe 6.

[0113] Step S402: The network device sends the first information to the terminal device.

[0114] It should be noted that the execution process of step S402 can be found in Figure 2 The specific description of step S202 is omitted here.

[0115] Step S403: If the first information determines that the first subframe is used to transmit the first channel, the terminal device determines the first subframe as the starting subframe in the corresponding subframe set for transmitting the first channel; if the first information determines that the first subframe is not used to transmit the first channel, the terminal device determines the next subframe adjacent to the first subframe in the subframe set corresponding to the first subframe as the starting subframe in the subframe set for transmitting the first channel.

[0116] In an embodiment of the present application, when a wireless frame corresponds to multiple subframe sets, after the terminal device receives the first information from the network device, it can determine the starting subframe for transmitting the first channel in each subframe set based on the first information. Specifically, if the first information determines that the first subframe in the first subframe set is used to transmit the first channel, the terminal device can determine the first subframe as the starting subframe for transmitting the first channel in the first subframe set; if the first information determines that the first subframe in the second subframe set is not used to transmit the first channel, the terminal device can determine the next subframe adjacent to the first subframe in the second subframe set as the starting subframe for transmitting the first channel in the second subframe set.

[0117] In one implementation, the first information may include a bitmap that may indicate whether the subframes in each subframe set in the wireless frame are actually configured for transmitting the first channel. When n consecutive subframes are required to transmit the first channel, after the terminal device determines that the first subframe in the first subframe set is actually configured for transmitting the first channel, it may also determine, through the bitmap in the first information, whether the n-1 subframes adjacent to the first subframe in the first subframe set are actually configured for transmitting the first channel. If the n-1 subframes adjacent to the first subframe in the first subframe set are actually configured for transmitting the first channel, the terminal device may determine the first subframe as the starting subframe in the first subframe set for transmitting the first channel. Similarly, after determining that the first subframe in the second subframe set is actually not configured for transmitting the first channel, the terminal device may also determine, through the bitmap in the first information, whether the next subframe adjacent to the first subframe in the second subframe set (such as the third subframe) and the n-1 subframes adjacent to the third subframe are actually configured for transmitting the first channel. If the third subframe and n-1 subframes adjacent to the third subframe are actually configured for transmitting the first channel, the terminal device may determine the third subframe as the starting subframe in the second subframe set for transmitting the first channel, where the numbers of the n-1 subframes are greater than the number of the third subframe.

[0118] For example, in a FeMBMS / unicast hybrid communication system, and if the radio frame is an FDD frame, only subframes 1 to 4 and 6 to 9 in the radio frame can be configured as second subframes. If three consecutive second subframes are required to transmit the first channel, and the radio frame corresponds to two subframe sets, the first subframe set includes subframes 1 to 4 in the radio frame, and the second subframe set includes subframes 6 to 9 in the radio frame. The bitmap in the first information may include 8 bits, and the value of each of the 8 bits indicates, in sequence, whether only subframes 1 to 4 and 6 to 9 in the radio frame are actually configured as second subframes. Each bit in the bitmap can have a value of "0" or "1." When the value is "0," it can indicate that the subframe corresponding to the bit is not configured as the second subframe. When the value is "1," it can indicate that the subframe corresponding to the bit is configured as the second subframe. If the first subframe in the first subframe set is subframe 1, the first subframe in the second subframe set is subframe 6, and the values ​​of subframes 1 and 6 in the bitmap are both "0", the subframe configuration scheme in the radio frame may include but is not limited to Figure 4b Three options are shown. Figure 4b The small and medium squares represent a subframe of a radio frame. The number in the small square indicates the number of the corresponding subframe in the radio frame. A small square filled with gray indicates that the subframe can theoretically be configured as the second subframe. A small square filled with white indicates that the subframe cannot be configured as the second subframe. A small square filled with gray and slashes indicates that the subframe is actually configured as the second subframe.

[0119] Depend on Figure 4b From the first scheme shown, it can be seen that the first subframes in the first subframe set and the second subframe set (i.e., subframes 1 and 6) are not configured as the second subframe, and the three subframes adjacent to the first subframe (i.e., subframes 1 to 4) in the first subframe set are all configured as the second subframe, and the three subframes adjacent to the first subframe (i.e., subframes 6) in the second subframe set (i.e., subframes 7 to 9) are all configured as the second subframe. At this time, the value of the bitmap in the first information is "01110111", and the terminal device can determine subframe 2 as the starting subframe for transmitting the first channel in the first subframe set, and determine subframe 7 as the starting subframe for transmitting the first channel in the second subframe set. Figure 4b In the second solution shown, the configuration of the subframes in the first subframe set is the same as Figure 4bThe configuration of the subframes in the first subframe set in the first scheme is the same and will not be repeated here; the first subframe in the second subframe set (i.e., subframe No. 6) and the two subframes adjacent to the first subframe (i.e., subframes No. 7 to No. 8) are not configured as the second subframe. At this time, the value of the bitmap in the first information is "01110000", and there is no starting subframe for transmitting the first channel in the second subframe set, that is, all subframes in the second subframe set are not actually used to transmit the first channel. In other words, there is only one starting subframe for transmitting the first channel in the wireless frame (i.e., subframe No. 2). Figure 4b In the third solution shown, the configuration of the subframes in the second subframe set is the same as Figure 4b The configuration of the subframes in the second subframe set in the first scheme is the same and will not be repeated here; the first subframe in the first subframe set (i.e., subframe 1) and the two subframes adjacent to the first subframe (i.e., subframes 2 to 3) are not configured as the second subframe. At this time, the value of the bitmap in the first information is "00000111", and there is no starting subframe for transmitting the first channel in the first subframe set, that is, all subframes in the first subframe set are not actually used to transmit the first channel. In other words, there is only one starting subframe for transmitting the first channel (i.e., subframe 7) in the wireless frame.

[0120] For example, when the values ​​of subframes 1 and 6 in the bitmap are both "0" and "1" respectively, and other conditions are the same as those in the above example, the configuration scheme of the subframes in the radio frame may include but is not limited to: Figure 4c Two options are shown. Figure 4c The bitmap value corresponding to the first solution in the scheme is "01111000". Since the three subframes (i.e., subframes 2 to 4) adjacent to the first subframe (i.e., subframe 1) in the first subframe set are all configured as second subframes, and the first subframe (i.e., subframe 6) and the two subframes adjacent to the first subframe (i.e., subframes 7 to 8) in the second subframe set are not all configured as second subframes. At this time, the terminal device can determine subframe 2 as the starting subframe for transmitting the first channel in the first subframe set. Since at least three consecutive second subframes are required to transmit the first channel, but only one subframe in the second subframe set is configured as the second subframe, there is no starting subframe for transmitting the first channel in the second subframe set. Although subframe 6 is configured as the second subframe, the network device may not send the first channel on the time-frequency resources corresponding to subframe 6. Figure 4cThe bitmap value corresponding to the second solution in the example is "00001110". Since the first subframe (i.e., subframe 1) and the two subframes adjacent to the first subframe (i.e., subframes 2 to 3) in the first subframe set are not configured as the second subframe, and the first subframe (i.e., subframe 6) and the two subframes adjacent to the first subframe (i.e., subframes 7 to 8) in the second subframe set are all configured as the second subframe, at this time, the terminal device can determine subframe 6 as the starting subframe for transmitting the first channel in the second subframe set, and there is no subframe for transmitting the first channel in the first subframe set. In one implementation, Figure 4c The bitmap value corresponding to the second solution in

[15] can also be "00001111", meaning that subframe 9 can also be configured as the second subframe. This way, there are four consecutive second subframes in the radio frame. In this case, the network device can also determine subframe 7 as the first subframe and further transmit the first channel in subframes 7 to 9. In other words, the network device can choose to transmit the first channel in subframes 6 to 8 or 7 to 9 as needed, providing greater flexibility in transmitting the first channel in the radio frame.

[0121] By implementing the embodiments of the present application, when a wireless frame corresponds to multiple subframe sets, the terminal device can determine the starting subframe for transmitting the first channel in each subframe set based on the first information, thereby facilitating improving the accuracy and efficiency of receiving the first channel.
