Description

Background
In a frame structure of a wireless communication system, one radio frame may include a plurality of subframes, and the length of each subframe is fixed. For example, in a Long Term Evolution (LTE) system of the universal mobile telecommunications technology, one radio frame includes 10 subframes each having a length of 1 ms.
With the rapid development of internet technology, a large number of new services are promoted. When a channel for transmitting a certain service requires at least two consecutive subframes, and the number of consecutive subframes that can be used for transmitting the service in one radio frame is greater than the number of consecutive subframes that are required for transmitting the channel for transmitting the service, the terminal may not be able to determine the starting subframe of the consecutive subframes that are used for transmitting the service in the radio frame. For example, when 2 consecutive subframes are required for transmitting a channel for service 1, and 3 consecutive subframes, i.e., subframes 0, 1, and 2 in a radio frame, can be used for transmitting service 1, a terminal cannot determine whether a starting subframe of consecutive subframes for transmitting service 1 is a subframe 0 or a subframe 1.

When at least two consecutive subframes are required for transmitting the first channel, and the number of consecutive subframes that can be used for transmitting the first channel in one radio frame is greater than the number of consecutive subframes that are actually required for transmitting the first channel, network device 101 may configure some or all subframes in the subframe set as subframes that are actually used for transmitting the first channel, generate the first information, and then send the first information to terminal device 102. The subframe set may include multiple consecutive subframes in the same radio frame, each subframe in the subframe set may theoretically be configured to transmit the first channel, and the subframe set includes the first subframe, and the first information may 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 a starting subframe of the subframe set, which is actually used for transmitting the first channel, according to the first information. Specifically, when the first subframe is a first subframe of 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 a starting subframe of the subframe set that is actually used to transmit the first channel.

It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: a Long Term Evolution (LTE) system, a fifth generation (5G) mobile communication system, a New Radio (NR) system, or other future new mobile communication systems. It should be further noted that, in fig. 1, the network device 101 sends the first information to one terminal device only for example, and does not constitute a limitation to the embodiment of the present application, and in other possible implementations, the network device 101 may also send the first information to other terminal devices, that is, the data processing method disclosed in the embodiment of the present application may be applied to not only a unicast communication system, but also a broadcast or multicast communication system, or may also be applied to a hybrid communication system. Both unicast and broadcast or multicast data may be transmitted in a hybrid communication system.
The hybrid communication system may be a Multimedia Broadcast Multicast Service (MBMS)/unicast hybrid communication system or a further enhanced Multimedia Broadcast Multicast Service (MBMS)/unicast hybrid communication system, where the MBMS service may be transmitted in the MBMS/unicast hybrid communication system, the unicast service (such as unicast data information or unicast control information) may also be transmitted, the MBMS service may also be transmitted in the femms/unicast hybrid communication system, and the femms/unicast hybrid communication system is a special MBMS/unicast hybrid communication system, and needs to satisfy at least one of the following two conditions: firstly, subframe number 4 and/or subframe number 9 in a radio frame in the system are configured as multimedia broadcast multicast single frequency network (MBSFN) subframes; second, there are subframes in the radio frame in the system that do not contain unicast control regions. The MBSFN subframe is a subframe used for transmitting an MBMS service, and the MBSFN subframe may be divided into an MBSFN area and a non-MBSFN area, where the MBSFN area may be a transmission resource used for transmitting a Physical Multicast Channel (PMCH) in the MBSFN subframe, the non-MBSFN area may also be referred to as a unicast control area, and the non-MBSFN area may be a transmission resource used for transmitting the non-PMCH.

It is to be understood that the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
The data processing method and the communication device provided by the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data processing method according to an embodiment of the present disclosure. The execution main bodies of step 201 and step 202 are network devices or chips in the network devices, and the execution main body of step 203 is a terminal device or a chip in the terminal device, and the network devices and the terminal devices are taken as the execution main bodies of the data processing method for example. As shown in fig. 2, the method may include, but is not limited to, the following steps:
step S201: the network device generates first information, where the first information is used to determine whether a first subframe is used for transmitting a first channel, where at least two consecutive subframes are required for transmitting the first channel, the first subframe is included in a subframe set, and the subframe set includes multiple consecutive subframes in the same radio frame.
In this embodiment, at least two consecutive subframes in one radio frame are required for transmitting the first channel, some or all subframes in one radio frame may be configured for transmitting the first channel, and all subframes in the subframe set may be configured for transmitting the first channel. Specifically, the network device may configure all subframes in the subframe set to be used for transmitting the first channel, and optionally, the network device may configure only a part of consecutive subframes in the subframe set to be used for transmitting the first channel. For example, when a radio frame includes 10 subframes, the 10 subframes are numbered from 0 to 9, and only subframes 1 to 4 in the radio frame may be configured for transmitting a first channel, and 2 consecutive subframes are required for transmitting 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 (e.g., subframes No. 1-2, subframes No. 2-3, or subframes No. 3-4 in the radio frame), the network device may actually configure both of the two consecutive subframes for transmission of the first channel. When the subframe set includes three or four consecutive subframes (e.g., subframes No. 1 to 3, subframes No. 2 to 4, or subframes No. 1 to 4 in the radio frame), the network device may actually configure two consecutive subframes of the three or four consecutive subframes for transmitting the first channel, and subframes of the subframe set that are not configured for transmitting the first channel may be used for transmitting other channels.
A radio frame may correspond to one or more subframe sets, where a subframe set includes multiple consecutive subframes in the radio frame, and it should be noted that different subframe sets include different subframes. For example, when only subframes No. 1 to 4 in a radio frame may be configured for transmitting a first channel and 2 consecutive subframes are required for transmitting the first channel, the radio frame may correspond to two subframe sets, the first subframe set may include subframes No. 1 to 2 in the radio frame, and the second subframe set may include subframes No. 3 to 4 in the radio frame. For another example, when 2 consecutive subframes are needed for transmitting the first channel, the radio frame may correspond to two subframe sets, and the first subframe set may include at least two consecutive subframes of subframes 1 to 4 (e.g., 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 set of subframes may include at least two consecutive subframes of subframes No. 6 to 9 (e.g., subframes No. 6 to 7, subframes No. 7 to 8, subframes No. 8 to 9, subframes No. 6 to 8, subframes No. 7 to 9, or subframes No. 6 to 9).
In the 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 the second subframe, the subframe is actually used for transmitting the first channel. Each subframe in the subframe set may theoretically be configured as a second subframe, i.e. each subframe in the subframe set may theoretically be used for transmitting the first channel, but in practical cases, a subframe in the subframe set may also be configured as a non-second subframe, i.e. a subframe in the subframe set may also be used for transmitting other channels than the first channel. In the embodiment of the present application, a subframe in the subframe set may be configured as one of a second subframe or a non-second subframe, and only when a subframe in the subframe set is configured as the second subframe, the subframe is actually used for transmitting the first channel. The subframe set may include a plurality of consecutive subframes, where the plurality of consecutive subframes may include a first subframe, and it should be noted that the plurality of consecutive subframes refer to consecutive sequence numbers of the plurality of subframes in the same radio frame. The first subframe may be a first subframe of a plurality of consecutive subframes in the subframe set, for example, if the subframe set includes subframes No. 1 to 4, the first subframe may be subframe No. 1.
After completing the configuration of the subframes in the subframe set, the network device may generate first information according to the configuration situation, where the first information may be used to determine whether the first subframe is actually used for transmitting 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 for transmitting the first channel. In an implementation, the network device may also generate the first information before configuration of subframes in the subframe set is not completed yet, and specifically, the network device may generate the first information before determining a configuration scheme of subframes in the subframe set but not 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 for transmitting the first channel. It should be noted that, in the embodiment of the present application, a certain subframe is described as being configured as a second subframe, which is equivalent to the subframe being configured for transmitting the first channel, and similarly, a certain subframe is described as being configured for transmitting the first channel, which is equivalent to the subframe being configured as a second subframe.
In one implementation, the first information may indicate whether, in addition to whether the first subframe is configured as the second subframe, other subframes except the first subframe in a subframe set to which the first subframe belongs may be configured as the second subframe. In one implementation, the first information may include a bitmap (bit-map), which may be used to indicate whether each subframe in the subframe set is actually configured as the second subframe, and a value of each bit in the bitmap may indicate whether the corresponding subframe is actually configured as the second subframe. For example, when a value of a first bit in the bitmap is "1", it may indicate that a subframe corresponding to the first bit is configured as a 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 one subframe in the subframe set, for example, when the subframe set includes subframes No. 1 to 4 in a radio frame, the bitmap may include 4 bits, where a value of a first bit is used to indicate whether the subframe No. 1 is configured as a second subframe; similarly, the value of the second bit is used to indicate whether the subframe No. 2 is configured as the second subframe; the value of the third bit is used for indicating whether the subframe No. 3 is configured as a second subframe or not; the value of the fourth bit is used to indicate whether subframe number 4 is configured as the second subframe.
In this embodiment of the application, the first information may be used to indicate a configuration situation of subframes in a subframe set corresponding to one radio frame, and optionally, the first information may also be used to indicate a configuration situation of subframes in a subframe set corresponding to two or more consecutive radio frames. For example, when one radio frame corresponds to a plurality of subframe sets (e.g., subframe set 1 and subframe set 2), the first information may be specifically 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 one radio frame, the bitmap in the first information may indicate the configuration of subframes in each subframe set in the radio frame. In the last example, if the subframe set 1 and the subframe set 2 both include 4 subframes, the bitmap in the first information may include 8 bits, and the first 4 bits in the bitmap are sequentially used to indicate whether the 4 subframes in the subframe set 1 are configured as the second subframe; the 5th bit to the 8 th bit in the bitmap are sequentially used to indicate whether 4 subframes in the subframe set 2 are configured as the second subframe.
For another example, the first information is used to indicate a configuration of subframes in a subframe set corresponding to the first radio frame and the second radio frame, where the first radio frame corresponds to one subframe set (e.g., subframe set 1), and the second radio frame corresponds to two subframe sets (e.g., subframe set 2 and subframe set 3), and at this time, the first information may 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, where the first radio frame and the second radio frame are two consecutive subframes. When the first information is used to indicate the configuration condition of subframes in the subframe sets corresponding to two or more consecutive radio frames, the bitmap in the first information may indicate the configuration condition of subframes in the subframe sets corresponding to two or more consecutive radio frames. In the last example, if the subframe set 1, the subframe set 2, and the 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 sequentially used to indicate whether the 4 subframes in the subframe set 1 are configured as the second subframe; the 5th bit to the 8 th bit in the bitmap are sequentially used for indicating whether 4 subframes in the subframe set 2 are configured as a second subframe; the 9 th bit to the 12 th bit in the bitmap are sequentially used to indicate whether 4 subframes in the subframe set 3 are configured as the second subframe.
In one implementation, the first channel may be a PMCH or other channel, the subframe (i.e., the second subframe) for transmitting the first channel may be an MBSFN subframe or other type of subframe, and the radio frame may be a radio Frequency Division Duplex (FDD) frame or a radio Time Division Duplex (TDD) frame.
It should be noted that subframes that can be configured as second subframes in radio frames transmitted in different communication systems may be different, and it should be noted that subframes that can be configured as second subframes in different types of radio frames may be different. Specifically, when the first channel is a PMCH and the second subframe is an 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 No. 0, No. 4, No. 5, and No. 9 in the radio frame cannot theoretically be used for transmitting the first channel, that is, subframes No. 0, No. 4, No. 5, and No. 9 cannot be theoretically configured as MBSFN subframes, that is, only subframes No. 1, No. 2, No. 3, No. 6, No. 7, and No. 8 in the radio frame may be configured as MBSFN subframes. In the MBMS/unicast hybrid communication system, when a radio frame is a TDD frame, subframes No. 0, No. 1, No. 2, No. 5, and No. 6 in the radio frame are theoretically not available for transmitting a first channel, i.e., subframes No. 0, No. 1, No. 2, No. 5, and No. 6 are theoretically not configurable as MBSFN subframes, that is, only subframes No. 3, No. 4, No. 7, No. 8, and No. 9 in the radio frame may be configurable as MBSFN subframes. In a femmbms/unicast hybrid communication system, that is, when a network device is a network device corresponding to a femmbms/unicast hybrid cell, and a radio frame is an FDD frame, subframes No. 0 and No. 5 in the radio frame cannot be theoretically used for transmitting a first channel, that is, subframes No. 0 and No. 5 cannot be theoretically configured as MBSFN subframes, that is, only subframes No. 1, No. 2, No. 3, No. 4, No. 6, No. 7, No. 8, and No. 9 in the radio frame may be configured as MBSFN subframes.
Optionally, in the MBMS/unicast hybrid communication system, when the radio frame is a TDD frame, the subframe 6 in the TDD frame may be configured as a downlink subframe or a special subframe. When the subframe 6 is configured as a downlink subframe, the subframe 6 may be specifically configured as an MBSFN subframe, and at this time, the subframes No. 3, No. 4, No. 6, No. 7, No. 8, and No. 9 in the TDD frame may be configured as MBSFN subframes. The special subframe may be composed of a downlink pilot time slot (DwPTS), an uplink pilot time slot (UpPTS), and a Guard Period (GP), where the DwPTS may transmit a downlink reference signal or control information; the UpPTS may transmit information of some short Random Access Channels (RACHs) and Sounding Reference Signals (SRS); GP is the guard interval between the uplink and downlink.
In the MBMS/unicast hybrid communication system, when the radio frame is an FDD frame and the second subframe is an MBSFN subframe, only subframes No. 1 to 3 and No. 6 to 8 in the radio frame may be configured as MBSFN subframes. If two continuous subframes are needed for transmitting the first channel, the radio frame may correspond to 1 or 2 subframe sets, and when the radio frame corresponds to 1 subframe set, the subframe set may include subframes No. 1 and No. 2, subframes No. 2 and No. 3, subframes No. 6 and No. 7, subframes No. 7 and No. 8, subframes No. 1 to No. 3, or subframes No. 6 to No. 8; when a radio frame corresponds to two subframe sets, the first subframe set may include subframes No. 1 and No. 2, subframes No. 2 and No. 3, or subframes No. 1 to No. 3, and the second subframe set may include subframes No. 6 and No. 7, subframes No. 7 and No. 8, or subframes No. 6 to No. 8. If three continuous subframes are needed for transmitting the first channel, the radio frame may correspond to 1 or 2 subframe sets, and when the radio frame corresponds to 1 subframe set, the subframe set may include subframes No. 1 to 3 or subframes No. 6 to 8; when a radio frame corresponds to two subframe sets, the first subframe set may include subframes No. 1 to 3, and the second subframe set may include subframes No. 6 to 8.
In the MBMS/unicast hybrid communication system, when the radio frame is a TDD frame and the second subframe is an MBSFN subframe, only subframes No. 3 to 4 and No. 7 to 9 in the radio frame may be configured as MBSFN subframes. If two continuous subframes are needed for transmitting the first channel, the wireless frame may correspond to 1 or 2 subframe sets, and when the wireless frame corresponds to 1 subframe set, the subframe set may include subframes No. 3 and No. 4, subframes No. 7 and No. 8, subframes No. 8 and No. 9, or subframes No. 7 to No. 9; when a radio frame corresponds to two subframe sets, the first subframe set may include subframes No. 3 and No. 4, and the second subframe set may include subframes No. 7 and No. 8, subframes No. 8 and No. 9, or subframes No. 7 to No. 9. If three consecutive subframes are needed for transmitting the first channel, the radio frame may correspond to 1 subframe set, and the subframe set may include subframes No. 7 to 9.
In a FeMBMS/unicast hybrid communication system, when a radio frame is an FDD frame and a second subframe is an MBSFN subframe, only numbers 1 to 4 and 6 to 9 in the radio frame can be configured as MBSFN subframes. If two continuous subframes are needed for transmitting the first channel, the radio frame may correspond to 1, 2, 3, or 4 subframe sets, and when the radio frame corresponds to 1 subframe set, the subframe set may include any two continuous subframes, any three continuous subframes, or any four continuous subframes among subframes No. 1 to 4 and subframes No. 6 to 9. When the radio frame corresponds to 2 subframe sets, the first subframe set may include one of any two consecutive subframes, any three consecutive subframes, or any four consecutive subframes of subframes nos. 1 to 4 and 6 to 9, and the second subframe set may include one of any two consecutive subframes, any three consecutive subframes, or any four consecutive subframes of nos. 1 to 4 and 6 to 9 except the first subframe set. The situation when the radio frame corresponds to 3 subframe sets is similar to that when the radio frame corresponds to 2 subframe sets, and the description is omitted here. When a radio frame corresponds to 4 subframe sets, a first subframe set may include subframes No. 1 to 2, a second subframe set may include subframes No. 3 to 4, a third subframe set may include subframes No. 6 to 7, and a fourth subframe set may include subframes No. 8 to 9.
In this embodiment, a radio frame may correspond to one or more subframe sets, where each subframe set includes a first subframe. Specifically, when the radio frame is an FDD frame in the MBMS/unicast hybrid communication system. If the FDD frame corresponds to a subframe set, and the subframe set includes subframes No. 1 to No. 3, the first subframe may be subframe No. 1 in the FDD frame. If the FDD frame corresponds to a subframe set, and the subframe set includes subframes No. 6 to No. 8, the first subframe may be subframe No. 6 in the FDD frame. When the FDD frame corresponds to two subframe sets, and the first subframe set includes subframes No. 1 to 3 and the second subframe set includes subframes No. 6 to 8, the first subframe in the first subframe set may be the subframe No. 1 in the FDD frame, and the first subframe in the second subframe set may be the subframe No. 6 in the FDD frame.
Similarly, when the radio frame is an FDD frame in the fesmbms/unicast hybrid communication system, if the FDD frame corresponds to a subframe set, and the subframe set includes subframes 1 to 4, the first subframe may be a subframe 1 in the FDD frame; if the FDD frame corresponds to a subframe set, and the subframe set includes subframes No. 6 to 9, the first subframe may be subframe No. 6 in the FDD frame. When the FDD frame corresponds to two subframe sets, and the first subframe set includes subframes No. 1 to 4 and the second subframe set includes subframes No. 6 to 9, the first subframe in the first subframe set may be the subframe No. 1 in the FDD frame, and the first subframe in the second subframe set may be the subframe No. 6 in the FDD frame.
Similarly, when the radio frame is a TDD frame in the MBMS/unicast hybrid communication system, if the TDD frame corresponds to a subframe set including subframes No. 3 to 4, the first subframe may be a subframe No. 3 in the TDD frame; if the TDD frame corresponds to a subframe set, and the subframe set includes subframes No. 7 to No. 9, the first subframe may be a subframe No. 7 in the TDD frame; if the TDD frame corresponds to a subframe set including subframes No. 6 to 9, the first subframe may be the subframe No. 6 in the TDD frame. When the TDD frame corresponds to two subframe sets, and the first subframe set includes subframes No. 3 to 4, and the second subframe set includes subframes No. 7 to 9, the first subframe in the first subframe set may be the subframe No. 3 in the TDD frame, and the first subframe in the second subframe set may be the subframe No. 7 in the TDD frame.
It should be noted that subframes included in different subframe sets are different, and different subframe sets do not include the same subframe, that is, when a radio frame corresponds to multiple subframe sets, each subframe in the radio frame exists in at most one subframe set, and cannot exist in multiple subframe sets.
Step S202: the network device sends the first information to the terminal device.
Specifically, after the network device generates the first information, the first information may be sent to the terminal device, so that the terminal device may determine, according to the first information, a starting subframe in the subframe set for transmitting the first channel. In one implementation, when the first channel is a PMCH, a starting subframe used for transmitting the first channel in the subframe set may refer to a starting subframe used for transmitting one complete PMCH symbol in the subframe set. For example, if 3 consecutive subframes are required for transmitting a complete PMCH symbol, the starting subframe may be the first subframe of the 3 consecutive subframes. It should be noted that one radio frame may transmit one or more complete PMCH symbols, but one subframe set may include at most one complete PMCH symbol, that is, one radio frame may include one or more starting subframes, and one subframe set may include at most one starting subframe.
In one implementation, the first information may be higher layer indication information, the higher layer indication information may be information transmitted in a higher layer protocol layer, and the higher layer protocol layer may refer to at least one protocol layer above a physical layer in an Open System Interconnection (OSI) model or other models. Specifically, the higher layer protocol layers may include, but are 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) layer.
Step S203: and the terminal equipment determines a starting subframe used for transmitting the first channel in the subframe set according to the first information.
Specifically, after receiving the first information from the network device, the terminal device may determine, according to the first information, a starting subframe used for transmitting the first channel in the subframe set, so as to facilitate accurate reception of the first channel according to the starting subframe.
When the first subframe is a first subframe of all consecutive subframes included in the subframe set and the first information determines that the first subframe is actually used for transmitting the first channel, the terminal device may determine the first subframe as a starting subframe actually used for transmitting 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 for transmitting the first channel, the terminal device may determine, as a starting subframe actually used for transmitting the first channel in the subframe set to which the first subframe belongs, other subframes except the first subframe in the subframe set to which the first subframe belongs, or the terminal device may determine that the starting subframe used for transmitting the first channel does not exist in the subframe set to which the first subframe belongs.
In one implementation, both the set of subframes 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 set of subframes. In one implementation, the first information may further include a subframe identifier, where the subframe identifier is used to identify the first subframe, and the terminal device may determine, according to the first information, whether the first subframe indicated by the subframe identifier is actually configured for transmitting the first channel.
In one implementation, after the terminal device determines the starting subframe, the subframe actually transmitting the first channel may be determined according to the number of consecutive subframes required for transmitting the first channel. For example, if 3 consecutive subframes are required for transmitting the first channel and the starting subframe is subframe No. 1, the terminal device may determine subframes No. 1 to 3 as subframes for actually transmitting the first channel. In one implementation, after the terminal device determines the subframe in which the first channel is actually transmitted, the terminal device may receive the first channel on the time-frequency resource corresponding to the determined subframe in which the first channel is actually transmitted. By the method, the situation that the first channel cannot be received from the correct time-frequency resource when the initial subframe cannot be determined can be avoided, and therefore the accuracy and the efficiency of receiving the first channel can be improved.
In one implementation, that 2 consecutive subframes are required for transmitting the first channel may indicate that all transmission resources corresponding to the 2 consecutive subframes are used for transmitting the first channel, or may indicate that a part of transmission resources corresponding to the 2 consecutive subframes are used for transmitting the first channel. When 2 consecutive subframes are required for transmitting the first channel and all transmission resources corresponding to the 2 consecutive subframes are used for transmitting the first channel, the terminal device may start receiving the first channel from a start position of a transmission resource corresponding to a start subframe of the 2 consecutive subframes.
In one implementation, a subframe for transmitting a first channel (i.e., a second subframe) may include a first region and a non-first region, the first region may be transmission resources in the second subframe for transmitting the first channel, and the non-first region may be transmission resources in the second subframe that are not used for transmitting the first channel. It should be noted that the size of the non-first region in the second subframe may be 0, that is, all transmission resources of the second subframe may be used for transmitting the first channel. When 2 consecutive subframes are required for transmitting the first channel and partial transmission resources corresponding to the 2 consecutive subframes are all used for transmitting the first channel, all first regions in the 2 consecutive subframes are used for transmitting the first channel, and correspondingly, the terminal device may receive the first channel from the first regions in the 2 consecutive subframes. It should be noted that 2 consecutive subframes are required for transmitting the first channel, and the terminal device receives the first channel from the first region in the 2 consecutive subframes for example only, and this does not constitute a limitation to the embodiment of the present application, and in other possible implementations, when 3 consecutive subframes or another number of consecutive subframes are required for transmitting the first channel, the terminal device may receive the first channel from the first region in the 3 consecutive subframes (or another number of consecutive subframes). It should be further noted that the first region may be one or more continuous OFDM symbols or a plurality of discontinuous OFDM symbols in the time domain of the second subframe. The first region may be one or more continuous resources or a plurality of discontinuous resources in the frequency domain of the second subframe, and specifically may be one or more continuous Resource Blocks (RBs) or Resource Elements (REs), or a plurality of discontinuous RBs or REs. When the first OFDM symbol in the first region in the starting subframe is the first OFDM symbol in the starting subframe, the terminal device may receive the first channel starting from the first OFDM symbol of the starting subframe; when the first OFDM symbol in the first region in the starting subframe is not the first OFDM symbol in the starting subframe, the terminal device may receive the first channel starting from the first OFDM symbol in the first region in the starting subframe, i.e., the terminal device may not receive the first channel starting from the first OFDM symbol in the starting subframe. Wherein, one RB may include a plurality of REs, and an RE (also referred to as a resource element) is the smallest resource unit in LTE physical resources. The 1 RE may represent 1 OFDM symbol in the time domain and 1 subcarrier in the frequency domain.
In one implementation, all OFDM symbols in the second subframe with a sub-carrier spacing (SCS) preset value may be used for transmitting the first channel. When the second subframe is an MBSFN subframe, all OFDM symbols in the MBSFN subframe with a preset subcarrier interval may be used to transmit the first channel. In one implementation, the preset value may include, but is not limited to, any one of 2.5kHz or 0.417kHz or less.
It should be noted that, when an MBSFN subframe satisfies any one of the following conditions, it may be indicated that all OFDM symbols in the subframe may be used for transmitting the first channel: MBSFN subframes with subcarrier spacing less than or equal to 0.417 kHz; a Cyclic Prefix (CP) length of the OFDM symbols in the MBSFN subframe is greater than or equal to 300 mus; the length of an OFDM symbol (or called a core OFDM symbol) which does not contain the CP in the MBSFN subframe is more than or equal to 2.4 ms; the length of an OFDM symbol in the MBSFN subframe is greater than or equal to 2.7 ms; a Fast Fourier Transform (FFT) size corresponding to a 20MHz bandwidth is greater than or equal to 73728; the FFT size for a 10MHz bandwidth is greater than or equal to 36864.
In one implementation, when a radio frame corresponds to a subframe set, and the first information is used to determine whether a subframe (i.e., a first subframe) is used for transmitting a first channel, the first information may further include a first value, where the first value is m, which may indicate that m subframes next to the first subframe are all configured as second subframes, and m may 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 radio frame are used for transmitting the first channel according to the first information. For example, when subframe 1 in a radio frame is a first subframe, and subframe 1 is configured as a second subframe, the first value is 1, and 2 consecutive second subframes are required for transmitting a first channel, the terminal device may determine that subframe 1 and subframe 2 in the radio frame are used for transmitting the first channel, and subframe 1 is a starting subframe. For another example, when subframe 1 in the radio frame is a first subframe, and subframe 1 is not configured as a second subframe, the first value is 2, and 2 consecutive second subframes are required for transmitting the first channel, the terminal device may determine that subframes 2 and 3 in the radio frame are used for transmitting the first channel, and subframe 2 is a starting subframe. In this way, the terminal device can quickly determine the subframe and the starting subframe for transmitting the first channel by carrying less bits of information in the first information.
In one implementation, when the radio frame corresponds to a plurality of subframe sets, and the first information is used to determine whether a first subframe in each subframe set is used for transmitting the first channel, the first information may further include a plurality of first values. The different first values may correspond to first subframes in different subframe sets, where a first value m may indicate that m subframes adjacent to the first subframe in the corresponding subframe set are all configured as second subframes, and m may be an integer greater than or equal to 0. For example, when a radio frame corresponds to two subframe sets, a subframe 1 in the first subframe set is a first subframe, the subframe 1 is configured as a second subframe, a first value corresponding to the first subframe set is 1, a subframe 6 in the second subframe set is the first subframe, the subframe 6 is not configured as the second subframe, a first value corresponding to the second subframe set is 2, and 2 consecutive second subframes are required for transmitting a first channel, the terminal device may determine that subframes 1 to 2 and subframes 7 to 8 in the radio frame are both used for transmitting the first channel, the subframe 1 is a starting subframe used for transmitting the first channel in the first subframe set, and the subframe 7 is a starting subframe used for transmitting the first channel in the second subframe set.
By implementing the embodiment of the application, the starting subframe used for transmitting the first channel in the subframe set can be determined according to the first information, so that the accuracy and the efficiency of receiving the first channel are improved.
Referring to fig. 3a, fig. 3a is a flowchart of another data processing method provided in this embodiment, which describes in detail how a network device configures a starting subframe of a first channel, and how a terminal device determines, according to first information, a starting subframe in a subframe set for transmitting the first channel. The execution main bodies of steps 301 to 303 are network devices or chips in the network devices, and the execution main body of step 304 is a terminal device or a chip in the terminal device, and the network devices and the terminal device are taken as the execution main bodies of the data processing method for example to be described below. The method may include, but is not limited to, the steps of:
step S301: the network device configures a first subframe as a starting subframe used for transmitting a first channel in a subframe set, wherein at least two continuous subframes are required for transmitting the first channel, the first subframe is included in the subframe set, and the subframe set comprises a plurality of continuous subframes in the same radio frame.
In particular, the network device may configure the first subframe as a starting subframe of a set of subframes for transmitting the first channel. When n consecutive subframes are needed for transmitting the first channel and the network device configures the first subframe as a starting subframe of the set of subframes for transmitting the first channel, it indicates that the first subframe and n-1 consecutive subframes adjacent to the first subframe are both used for transmitting the first channel. Wherein n may be an integer greater than or equal to 2, and configuring the first subframe as a starting subframe for transmitting the first channel in the subframe set is equivalent to configuring the first subframe as a second subframe.
In one implementation, if the network device does not configure the first subframe as a starting subframe of the set of subframes for transmitting the first channel, the network device may configure a next subframe of the set of subframes adjacent to the first subframe as the starting subframe of the set of subframes for transmitting the first channel. When 2 consecutive second subframes are needed for transmitting the first channel, taking the schematic diagram of the configuration scheme of the subframes in the radio frame shown in fig. 3b as an example, the small square in fig. 3b represents one subframe of the radio frame, the number in the small square represents the number of the corresponding subframe in the belonging radio frame, the gray filled small square represents that the subframe can be theoretically configured as the second subframe, the white filled small square represents that the subframe cannot be configured as the second subframe, and the gray and oblique filled small square represents that the subframe is actually configured as the second subframe. As shown in fig. 3b, subframes 1 to 3 in a radio frame may be configured as second subframes (i.e. subframes 1 to 3 may be configured to transmit a first channel), a subframe set corresponding to the radio frame includes subframes 1 to 3, and when the first subframe in the subframe set is subframe 1 and subframe 1 is actually configured as the second subframe, the network device may configure subframe 2 as the second subframe, so that a subsequent first channel may be transmitted on subframe 1 and subframe 2. At this time, the starting subframe for transmitting the first channel in the subframe set is subframe No. 1. When the first subframe in the subframe set is subframe No. 1 and subframe No. 1 is not configured as the second subframe, as shown in fig. 3c, the network device may configure subframe No. 2 and subframe No. 3 as the second subframe, so that the first channel may be transmitted on subframe No. 2 and subframe No. 3 subsequently. At this time, the starting subframe for transmitting the first channel in the subframe set is subframe number 2.
In one implementation, if the network device does not configure the first subframe and a next subframe adjacent to the first subframe as a starting subframe for transmitting the first channel in the subframe set, and the number of subframes other than the first subframe and the next subframe adjacent to the first subframe in the subframe set is greater than or equal to the number of consecutive subframes required for transmitting the first channel, the network device may configure a second subframe after the first subframe as the starting subframe for transmitting the first channel in the subframe set; if the number of subframes other than the first subframe and the next subframe adjacent to the first subframe in the subframe set is less than the number of consecutive subframes required for transmitting the first channel, the subframe set does not have a starting subframe for transmitting the first channel, that is, all subframes in the subframe set are not actually used for transmitting the first channel.
Step S302: the network device generates first information that determines that the first subframe is for transmission of a first channel.
In this embodiment, the network device may generate first information according to whether the first subframe is configured as a starting subframe for transmitting the first channel in the subframe set, where the first information is used to determine whether the first subframe is used for transmitting the first channel. Specifically, if the network device configures the first subframe as a starting subframe used for transmitting the first channel in the subframe set, the first information generated by the network device may be used to determine that the first subframe is used 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 for transmitting the first channel if the network device does not configure the first subframe as a starting subframe of the set of subframes for transmitting the first channel.
Step S303: the network device sends the first information to the terminal device.
It should be noted that, the execution process of step S303 can refer to the detailed description of step S202 in fig. 2, which is not described herein again.
Step S304: and the terminal equipment determines the first subframe as a starting subframe used for transmitting the first channel in the subframe set.
In this embodiment, after receiving the first information from the network device, the terminal device may determine, according to the first information, a starting subframe used for transmitting the first channel in the subframe set, so as to facilitate accurate reception of the first channel according to the starting subframe. Specifically, if the first information determines that the first subframe is used for transmitting the first channel, the terminal device may determine the first subframe as a starting subframe used for transmitting the first channel in the subframe set; if the first information determines that the first subframe is not used for transmitting the first channel, the terminal device may determine a next subframe adjacent to the first subframe in the subframe set as a starting subframe for transmitting the first channel in the subframe set.
In one implementation, the first information may be used to indicate whether subframes other than the first subframe in a subframe set to which the first subframe belongs are used for transmitting the first channel, in addition to determining whether the first subframe is used for transmitting the first channel. When n consecutive subframes are needed for transmitting the first channel, if the terminal device determines, through the first information, that all the n consecutive subframes with the first subframe as a starting subframe are configured to be used for transmitting the first channel, the terminal device may determine the first subframe as the starting subframe used for transmitting the first channel in a subframe set to which the first subframe belongs. If the terminal device determines, through the first information, that the first subframe is not used for transmitting the first channel, the terminal device may determine, through the first information, whether n consecutive subframes starting with a next subframe adjacent to the first subframe are all configured for transmitting the first channel, and if n consecutive subframes starting with the next subframe adjacent to the first subframe are all configured for transmitting the first channel, the terminal device may determine the next subframe adjacent to the first subframe as a starting subframe for transmitting the first channel in a subframe set to which the first subframe belongs. If the next subframe adjacent to the first subframe is not configured to be used for transmitting the first channel, the terminal device may determine, through the first information, whether n consecutive subframes starting with the second subframe after the first subframe are all configured to be used for transmitting the first channel, and if n consecutive subframes starting with the second subframe after the first subframe are all configured to be used for transmitting the first channel, determine the second subframe after the first subframe as the starting subframe in the subframe set to which the first subframe belongs, for transmitting the first channel. The terminal device may determine that there is no starting subframe for transmitting the first channel in the subframe set to which the first subframe belongs, until the number of subframes other than the subframe that has been determined not to be used for transmitting the first channel in the subframe set to which the first subframe belongs is less than n. Wherein n may be an integer greater than or equal to 2. In one implementation, the terminal device may determine, through a bitmap in the first information, whether each subframe in the set of subframes is configured for transmitting the first channel.
By implementing the embodiment of the application, if the first information determines that the first subframe is used for transmitting the first channel, the terminal device may determine the first subframe as a starting subframe used for transmitting the first channel in the subframe set; if the first information determines that the first subframe is not used for transmitting the first channel, the terminal device may determine a next subframe adjacent to the first subframe in the subframe set as a starting subframe for transmitting the first channel in the subframe set. In this way, it is beneficial to improve the accuracy and efficiency of receiving the first channel.
Referring to fig. 4a, fig. 4a is a flowchart illustrating a further data processing method according to an embodiment of the present application, where the method details how a network device configures a starting subframe of a first channel in a case that a radio frame corresponds to a plurality of subframe sets, and how a terminal device determines, according to first information, the starting subframe for transmitting the first channel in each subframe set. The execution main bodies of step 401 and step 402 are network devices or chips in the network devices, and the execution main body of step 403 is a terminal device or a chip in the terminal device, and the network devices and the terminal device are taken as the execution main bodies of the data processing method for example. The method may include, but is not limited to, the steps of:
step S401: the network equipment generates first information, wherein the first information is used for determining whether a first subframe is used for transmitting a first channel, at least two continuous subframes are needed for transmitting the first channel, the number of the first subframes is multiple, 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, and the subframe set includes multiple continuous subframes in the same radio frame.
In this embodiment, one radio frame may correspond to one or more subframe sets, each subframe set includes one first subframe, and the first subframes in different subframe sets are different. Taking an example that one radio frame corresponds to two subframe sets, if subframes that can be theoretically used for transmitting the first channel in the radio frame include subframes 1 to 3 and subframes 6 to 8, 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. The first subframe in the first subframe set may be subframe number 1, and the first subframe in the second subframe set may be subframe number 6.
Step S402: the network device sends the first information to the terminal device.
It should be noted that, the execution process of step S402 can refer to the detailed description of step S202 in fig. 2, which is not described herein again.
Step S403: if the first information determines that the first subframe is used for transmitting the first channel, the terminal equipment determines the first subframe as a starting subframe used for transmitting the first channel in a corresponding subframe set; if the first information determines that the first subframe is not used for transmitting the first channel, the terminal device determines a next subframe adjacent to the first subframe in a subframe set corresponding to the first subframe as a starting subframe used for transmitting the first channel in the subframe set.
In this embodiment of the application, when a radio frame corresponds to multiple subframe sets, after receiving first information from a network device, a terminal device may determine, according to the first information, a starting subframe used for transmitting a first channel in each subframe set. Specifically, if the first information determines that a first subframe in the first subframe set is used for transmitting the first channel, the terminal device may determine the first subframe as a starting subframe in the first subframe set for transmitting the first channel; if the first information determines that the first subframe in the second subframe set is not used for transmitting the first channel, the terminal device may determine a next subframe adjacent to the first subframe in the second subframe set as a starting subframe for transmitting the first channel in the second subframe set.
In one implementation, the first information may include a bitmap that may indicate whether subframes in each set of subframes in a radio frame are actually configured for transmission of the first channel. When n consecutive subframes are needed for transmitting the first channel, the terminal device may further determine, through a bitmap in the first information, whether n-1 subframes adjacent to the first subframe in the first subframe set are actually configured for transmitting the first channel after determining that the first subframe in the first subframe set is actually configured for transmitting the first channel. If 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 a starting subframe for transmitting the first channel in the first subframe set. Similarly, after determining that the first subframe in the second subframe set is not actually configured for transmitting the first channel, the terminal device may further determine, through a bitmap in the first information, whether a next subframe (e.g., a third subframe) adjacent to the first subframe in the second subframe set and n-1 subframes adjacent to the third subframe are actually configured for transmitting the first channel. If the third subframe and the n-1 subframes adjacent to the third subframe are actually both configured for transmitting the first channel, the terminal device may determine the third subframe as a starting subframe for transmitting the first channel in the second set of subframes. Wherein the number of the n-1 subframes is greater than the number of the third subframe.
For example, in a hybrid femmbms/unicast communication system, and the radio frame is an FDD frame, only subframes No. 1 to 4 and No. 6 to 9 in the radio frame may be configured as the second subframe. If three continuous second subframes are needed for transmitting the first channel, and the wireless frame corresponds to 2 subframe sets, the first subframe set comprises subframes No. 1 to No. 4 in the wireless frame, and the second subframe set comprises subframes No. 6 to No. 9 in the wireless frame. The bitmap in the first information may include 8 bits, a value of each bit in the 8 bits sequentially indicates whether only subframes No. 1 to 4 and No. 6 to 9 in the radio frame are actually configured as the second subframe, a value of each bit in the bitmap may be "0" or "1", when the value is "0", it may indicate that a subframe corresponding to the bit is not configured as the second subframe, and when the value is "1", it may indicate that a subframe corresponding to the bit is configured as the second subframe. If the first subframe in the first subframe set is subframe No. 1, the first subframe in the second subframe set is subframe No. 6, and the values of subframe No. 1 and subframe No. 6 in the bitmap are both "0", the configuration schemes of the subframes in the radio frame may include, but are not limited to, the three schemes shown in fig. 4 b. In fig. 4b, the small squares represent one subframe of a radio frame, the numbers in the small squares represent the numbers of the corresponding subframes in the belonging radio frame, the gray filled small squares represent that the subframe can be theoretically configured as a second subframe, the white filled small squares represent that the subframe cannot be configured as a second subframe, and the gray and oblique filled small squares represent that the subframe is actually configured as a second subframe.
As can be seen from the first scheme shown in fig. 4b, neither the first subframe (i.e., subframe No. 1 and subframe No. 6) in the first subframe set nor the second subframe set is configured as the second subframe, and 3 subframes (i.e., subframes No. 2 to 4) adjacent to the first subframe (i.e., subframe No. 1) in the first subframe set are configured as the second subframe, and 3 subframes (i.e., subframes No. 7 to 9) adjacent to the first subframe (i.e., subframe No. 6) in the second subframe set are configured as the second subframe. At this time, the value of the bitmap in the first information is "01110111", and the terminal device may determine the subframe No. 2 as a starting subframe used for transmitting the first channel in the first subframe set, and determine the subframe No. 7 as a starting subframe used for transmitting the first channel in the second subframe set. In the second scheme shown in fig. 4b, the configuration of the subframes in the first subframe set is the same as the configuration of the subframes in the first subframe set in the first scheme in fig. 4b, and is not repeated herein; neither the first subframe (i.e., subframe No. 6) in the second subframe set nor 2 subframes (i.e., subframes No. 7 to 8) adjacent to the first subframe are configured as the second subframe, at this time, the value of the bitmap in the first information is "01110000", and the second subframe set does not have a starting subframe for transmitting the first channel, that is, all subframes in the second subframe set are not actually used for transmitting the first channel, in other words, only one starting subframe (i.e., subframe No. 2) for transmitting the first channel exists in the radio frame. In the third scheme shown in fig. 4b, the configuration of the subframes in the second subframe set is the same as the configuration of the subframes in the second subframe set in the first scheme in fig. 4b, and is not repeated herein; neither the first subframe (i.e., subframe No. 1) in the first subframe set nor 2 subframes (i.e., subframes No. 2 to 3) adjacent to the first subframe are configured as the second subframe, at this time, the value of the bitmap in the first information is "00000111", and the first subframe set does not have a starting subframe for transmitting the first channel, that is, all subframes in the first subframe set are not actually used for transmitting the first channel, in other words, only one starting subframe (i.e., subframe No. 7) for transmitting the first channel exists in the radio frame.
For another example, when the values of the subframes No. 1 and No. 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, the two schemes shown in fig. 4 c. The value of the bitmap corresponding to the first scheme in fig. 4c is "01111000", because all 3 subframes (i.e., subframes No. 2 to 4) adjacent to the first subframe (i.e., subframe No. 1) in the first subframe set are configured as the second subframe, and not all the first subframe (i.e., subframe No. 6) and 2 subframes (i.e., subframes No. 7 to 8) adjacent to the first subframe in the second subframe set are configured as the second subframe. At this time, the terminal device may determine subframe No. 2 as a starting subframe used for transmitting the first channel in the first subframe set, since at least 3 consecutive second subframes are required for transmitting the first channel, but only one subframe in the second subframe set is configured as the second subframe, the starting subframe used for transmitting the first channel does not exist in the second subframe set, and although the subframe No. 6 is configured as the second subframe, the network device may not transmit the first channel on the time-frequency resource corresponding to the subframe No. 6. The value of the bitmap corresponding to the second scheme in fig. 4c is "00001110", since neither the first subframe (i.e., subframe No. 1) in the first subframe set nor 2 subframes adjacent to the first subframe (i.e., subframes No. 2 to 3) are configured as the second subframe, and both the first subframe (i.e., subframe No. 6) in the second subframe set and 2 subframes adjacent to the first subframe (i.e., subframes No. 7 to 8) are configured as the second subframe, at this time, the terminal device may determine subframe No. 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 an implementation manner, a value of the bitmap corresponding to the second scheme in fig. 4c may also be "00001111", that is, the subframe 9 may also be configured as the second subframe, so that there are 4 consecutive second subframes in the radio frame, at this time, the network device may also determine the subframe 7 as the first subframe, and further transmit the first channel on the subframe 7 to 9. That is to say, the network device may select to transmit the first channel on the number 6 to number 8 subframes or the number 7 to number 9 subframes as required, and in this way, the first channel may be transmitted in the radio frame more flexibly.
By implementing the embodiment of the application, the terminal device can determine the initial subframe used for transmitting the first channel in each subframe set according to the first information under the condition that the wireless frame corresponds to the plurality of subframe sets, so that the accuracy and the efficiency of receiving the first channel are improved.
