Description

[0001] This application is a divisional application of patent application with application number 201610879006.X (the application date of the original application is September 30, 2016, and the name of the invention is a method, device and equipment for transmitting public control information). Technical Field

[0002] The present application relates to the field of communications, and in particular to a method, device, equipment and storage medium for sending and detecting a paging message. Background Art

[0003] As one of the core technologies for future communications, high frequency communication is one of the main development directions for NR (New Radio, NR) enhancement. The notable feature of high frequency communication is that it is based on beam communication, and considering the cost issue, it tends to be a hybrid beam communication, that is, a radio frequency beam plus a baseband beam. However, a notable feature of the radio frequency beam is that a radio frequency link on an orthogonal frequency division multiplexing (OFDM) symbol can only correspond to one radio frequency beam direction. Therefore, in order to cover different beam directions, multiple OFDM symbols are required.

[0004] The characteristic of public control information is that it is sent on demand, but it requires cell coverage. At this time, the scanning beam needs to cover the entire cell. If a method similar to LTE is adopted, the entire cell can only be covered by multiple subframes, and the transmission beams of multiple subframes are polled, which limits the flexible scheduling of data signals. Therefore, it is necessary to consider the transmission of public control information under high-frequency communication. Summary of the invention

[0427] The present invention is described in detail below in conjunction with specific application examples.

[0428] Embodiment 1

[0429] In this embodiment, the base station uses M transmission resources to send public control information on M time domain resources, each of which includes N time domain symbols; the time domain resource where the public control information of the transmission resource is located is determined according to the transmission resource index and the N value.

[0430] The different sending resources are distinguished by one or more of the following resource types: sending beam resources, sending antenna resources, sending port resources, sending frequency domain resources, sending sequence resources, and sending time domain resources.

[0431] Figure 6a-6cThe figure shows that when the N value is different for the same transmission resource, the corresponding time domain symbol resources are different, if the starting time domain symbol is symbol 0. Figure 6a As shown in FIG. 1 , when N is 1, the time domain resource occupied by transmission resource 1 (i.e., transmission beam group 1 in the figure) is symbol 1; when N is 2, the time domain resource occupied by transmission resource 1 is symbol {2,3}, as shown in FIG. Figure 6b As shown; when the value of N is 3, the time domain resources occupied by the transmission resource 1 are symbols {3,4,5}, such as Figure 6c The base station needs to determine the time domain resources occupied by each sending resource according to the sending resource index and the N value.

[0432] For the N value, the first method is to determine the N value based on at least one of the following information: system bandwidth, subcarrier spacing, the number of subcarriers included in a symbol, the length of the public control information, when the public control information includes a public message and a public control signaling indicating relevant configuration information of the public message, the length includes the public message and the public control signaling. The second implementation method is to notify the N value in a broadcast message. The third method is to notify the N value through the first-level public control information, preferably, the N value corresponding to the first-level public control information notifying the N value is a fixed value, or the N value corresponding to the system message notifying the N value belongs to a set.

[0433] In the above-mentioned method of determining the N value, one is to determine an N value, and the other is to determine set B in set A to which the N value belongs, wherein set A includes at least two natural numbers, and set B is a subset of set A, and set B includes at least one natural number. When the determined N value has multiple values, the base station determines the N value according to the public control signaling currently sent, and / or the length of the second type of public message indicated by the public control signaling, and preferably notifies the terminal of the N value, such as through a physical control format indicator channel (PCFICH) similar to LTE or through the public control signaling to notify the N value. The terminal blindly detects the public control signaling for multiple N values, or blindly detects the public message to determine the N value. That is, for example, the terminal needs to Figure 6a to Figure 6c The specific sending method adopted by the blind detection base station.

[0434] Specifically, Figure 7 As shown, there is a one-to-one correspondence between the M transmission resources and the time domain resources for transmitting the synchronization signal. The terminal obtains its own optimal receiving mode and its own downlink transmission resource set through the synchronization signal, wherein the downlink transmission resource set includes at least one transmission resource. For each transmission resource in the transmission resource set, the terminal obtains the time domain symbol for detecting the common message according to the transmission resource index and the N value, as shown in FIG. Figure 7The terminal is shown to receive in a preferred receiving mode on the C-PDCCH (i.e., the public control signaling) and / or C-PDSCH (i.e., the public message) time domain resources. Specifically, for example, the terminal obtains its corresponding transmission resource set as {transmission resource 0, transmission resource 1}, and the N value determined by the terminal belongs to the set {1,2,3}, then the terminal detects the public message on symbols {1}, {2,3}, {3,4,5} for transmission resource 1. For transmission resource 0, the terminal detects the public control information on symbols {0}, {0,1}, {0,1,2} in sequence. Figure 7 Since the N value is uncertain and belongs to a set, the terminal uses the same RF receiving method on different transmission resources on the C-PDCCH / C-PDSCH time domain resources. Of course, if the receiving method is a baseband receiving method, that is, the RF beams corresponding to different receiving methods are the same, the terminal can first use the same RF beam to receive all transmission resources, and then for each N value assumption, different transmission resources can be received using different previously trained receiving methods. Of course, this embodiment does not exclude that when the N value is a fixed value, the terminal uses the preferred receiving method corresponding to the transmission resource for different transmission resources. For example, through the previous receiving method, it is trained that transmission resource 0 corresponds to receiving method 1, and transmission resource 1 corresponds to receiving method 0. Then, in the C-PDCCH / C-PDSCH domain, reception method 1 is used for transmission resource 0, and reception method 0 is used for transmission resource 1.

[0435] exist Figure 7 There are M time domain resources for synchronization signals, and one time domain resource for sending synchronization signals corresponds to one time domain resource for sending public control information. Of course, this embodiment does not exclude the correspondence between one time domain resource for sending synchronization signals and multiple time domain resources for sending public control information. The different sending resources can also establish a corresponding relationship with at least one of the following signals: there is a one-to-one correspondence between the M sending resources and the M time domain resources of the broadcast channel; there is a one-to-one correspondence between the M sending resources and the M time domain resources of the measurement reference signal; wherein one time domain resource of the measurement reference signal includes at least one measurement reference signal port;

[0436] The first implementation of the content included in a time domain transmission resource is to directly send a public message, and the second implementation of the content included in a time domain transmission resource is to send a public message and a public control signaling, wherein the public control signaling is used to indicate the relevant configuration information of the public message. At this time, for the multiplexing method of the public control signaling and the public message, the first implementation method is that the public control signaling is sent in the time domain symbol with the smallest index of the N time domain symbols, such as Figure 8a-8b As shown. Figure 8a-8bAssume that the base station and the terminal agree that the N value belongs to {1,2}, and the terminal needs to Figure 8a and Figure 8b The blind detection base station sends the Figure 8a still Figure 8b For each N value, the terminal first detects the DCI information (i.e., the public control signaling information) in the time domain symbol with the smallest index in a determined time domain resource. The second implementation method is that the public control signaling can occupy resources in N time domain symbols, such as Figure 8c As shown, the N value is 2. At this time, the public control signaling in each sending resource can occupy resources in 2 time domain symbols, and the DCI in the 2 symbols can be repeated transmission of the same DCI or different segments of the same DCI.

[0437] In this embodiment, the common message includes at least one of the following messages: system message, paging message, RAR message, RRC message, TPC information. In this embodiment, the transmission beam group i is the transmission resource i, i belongs to {0, 1, ..., M-1}.

[0438] Embodiment 2

[0439] In this embodiment, M transmission resources are used to transmit common control information on M time domain resources, where one time domain resource includes N time domain symbols, and the common control information and the measurement reference signal are transmitted in the N time domain symbols in one time domain resource.

[0440] The public control information and the measurement reference signal are sent in N time domain symbols in a time domain resource. In the first mode, the measurement reference signal and the public control information are time-division multiplexed. The measurement reference signal is sent before the public control information. The number of repeated transmissions of the measurement reference signal is greater than or equal to the number of repeated transmissions of the public control information. For example, the number of repeated transmissions of the measurement reference signal is R, and the number of repeated transmissions of the public control information is 1, that is, the receiving mode is trained first, and then the public control information is received in the optimal receiving mode. As shown in 9a, the measurement reference signal is sent before the public control information, and the public control information includes at least one of the following information: C-CCCH, C-PDSCH. The time-frequency resource of sending resource 0 is composed of R measurement reference signal resources of sending resource 0 and public control information resources of sending resource 0.

[0441] When the public control information is a paging message, and / or a control signaling indicating configuration information related to the paging message, the number of repetitions of the measurement reference signal may be different in different paging opportunities, that is, the number of repetitions of the measurement reference signal in one time domain resource may be the maximum number of receiving modes corresponding to all users that can send paging in the paging opportunity, or the maximum number of receiving modes corresponding to all users included in the paging message currently sent in the paging opportunity, wherein the paging opportunity consists of the M time domain resources. Figure 9b and Fig.9c As shown, the measurement reference signal is repeatedly sent four times in the first paging opportunity of the base station. Figure 9b As shown, the number of repetitions of sending the measurement reference signal in the second paging opportunity of the base station is 8 times. Fig.9c As shown, the paging opportunity of user group 1 can be sent in the first paging opportunity, and the paging opportunity of user group 2 can be sent in the second paging opportunity. The first scheme for repeatedly sending the measurement reference signal in each paging opportunity is determined according to the maximum number of receiving modes of the users that can be paged in the paging opportunity. For example, the paging message of user group 1 can be sent in the first paging opportunity, and user group 1 includes {user 1, user 2, user 3, ..., user 10}, wherein the user identification numbers corresponding to these 10 users are different, and the number of receiving modes corresponding to these 10 users is {(user 1, 1 receiving mode), (user 2, 2 receiving modes), (user 3, 4 receiving modes), ..., (user 10, 1 receiving mode)}, then the maximum number of receiving modes corresponding to these 10 users is 4. In this scheme, unless the users included in the next paging opportunity change, the number of transmission beam repetitions sent by a paging opportunity corresponding to a user group at different times is the same. The second scheme for repeating the number of times the measurement reference signal is sent in each paging opportunity is determined based on the maximum number of receiving modes of the user currently being paged in the paging opportunity. For example, in the first paging opportunity above, user group 1 can be paged, and user group 1 includes {user 1, user 2, user 3, ..., user 10}. Currently, there are paging information for user 1 and user 2, and the number of receiving modes corresponding to user 1 and user 2 is (user 1, 1 receiving mode), (user 2, 2 receiving modes). At this time, the number of times the measurement reference signal is sent in this paging opportunity is the maximum number of receiving modes corresponding to user 1 and user 2. Then, the number of times the measurement reference signal is sent is 2. In the above scheme, the user's receiving mode capability needs to be fed back to the base station by the terminal. In the above scheme, the transmission of the measurement reference signal first polls different transmission resources, and then transmits it repeatedly. This can be compatible with terminals with different receiving mode capabilities, such as Figure 9bAs shown, if user 2 is in 2 receiving modes, user 2 can be awakened in two measurement reference signal scanning cycles before the public control information. If user 4 is in 4 receiving modes, user 4 can be awakened in four measurement reference signal scanning cycles before the public control information. In the above implementation, preferably, the demodulation reference signal is not sent on the public control information, and the measurement reference signal is used as the demodulation reference signal, for example, Figure 9a to Figure 9c In the C-CCCH / C-PDSCH domain, there is no demodulation reference signal. The terminal obtains the preferred transmission resource and receiving mode in the measurement reference signal domain. The measurement reference signal corresponding to the transmission resource and receiving mode is used as the demodulation reference signal corresponding to the transmission resource and receiving mode in the public control information domain, such as Figure 9a As shown, if user 2 obtains transmission resource 0 and reception mode 1 in the 8th scanning cycle of the measurement reference signal described in the figure, then the demodulation reference signal of its transmission resource 0 in the C-CCCH / C-PDSCH domain can be the measurement reference signal resource of transmission resource 0 in the 8th scanning cycle. Of course, if the interval between the measurement reference signal and the public control information resource is relatively small, and / or the number of time domain resources required for a beam scan is relatively small, the measurement reference signal can be used as a demodulation reference signal, otherwise it cannot be used as a demodulation reference signal, or whether the measurement reference signal can be used as a demodulation reference signal requires signaling indication. The signaling indication is preferably notified before M time domain resources, otherwise the demodulation of the public control information is a problem.

[0442] The common control information and the measurement reference signal are sent in N time domain symbols in one time domain resource. In the second mode, the measurement reference signal and the common control information are frequency-division multiplexed, and the measurement reference signal and the common control information are repeatedly sent. Preferably, the measurement reference signal is a demodulation reference signal.

[0443] When the public control information is a paging message, and / or a control signaling indicating configuration information related to the paging message, the number of repeated transmissions of the measurement reference signal and the public control information is similar to the time-division measurement reference signal and the public control information above. The number of repetitions can be the maximum number of receiving modes corresponding to all users to which paging can be sent in the paging opportunity, or can be the maximum number of receiving modes corresponding to all users included in the paging message currently sent in the paging opportunity.

[0444] When the number of receiving modes of the terminal corresponding to different information in the public control information is different, one way is that in R repeated transmissions, each corresponding information is the same, and another way is to further divide the information according to the number of receiving modes, and the number of repeated transmissions of the information belonging to the same number of receiving modes is the same. For example, the public message is a paging message, and the paging message includes the paging information of terminals 1 to 4. The number of receiving modes corresponding to terminals 1 to 4 is 1, 2, 2, and 4, respectively. If the paging message is sent on 4 time domain symbols, the paging message of terminal 1 is sent on only one symbol, the paging message of terminals 2 and 3 is sent on two time domain symbols, and the paging message of terminal 4 is sent on 4 time domain symbols, resulting in the paging message of 4 users being sent on one time domain symbol of the 4 time domain symbols, and the paging message of 3 users being sent on 2 of the symbols, and the paging message of 4 users being sent on 1 of the symbols. For the time domains of these 4 symbols, the paging elements included in the paging messages sent are successively reduced or increased from the front to the back, and one paging element in the paging message corresponds to an identifier of a user. like Figure 9d As shown, in the multiple repeated transmissions of the same transmission resource, the paging information sent in each time division resource is different. The paging message for user 1 is only sent on one time division resource, and the paging message for user 4 is sent on four repeated resources. At this time, for user 4, different receiving methods need to be used to search for paging messages on these four time division resources, but the lengths of paging messages on different time division resources are different. The first solution is that the public control signaling on each time division resource indicates the resources occupied by the paging message and the length information of the paging message. The second solution is that there is no public control signaling, and the paging message is sent directly. At this time, the terminal needs to perform blind detection on the lengths of multiple paging messages on each time division resource. The third solution is to send the paging message in blocks, and each block includes a fixed number of paging message lengths. The receiving end obtains the range of its own blind detection paging message through the terminal identification signal. As shown Fig.9e As shown, for each terminal, the length of the paging message detected on the different time-division resources that are repeatedly sent is the same. At this time, different terminals can obtain the detection range of their paging messages through the corresponding TMSI information. For example, the user group included in a paging opportunity includes {user 1 to user 10}. When these 10 users are divided into 4 groups, the space for users in the same group to detect paging messages is the same, or the scrambling information for detecting paging messages is the same. In short, the search space for users to detect paging messages is obtained according to the user identification number and / or the number of receiving modes. The user identification number is similar to the UE_ID information in LTE. For example, the UE_ID information is obtained according to the TMSI information. Of course, in the above implementation method, a basic block may include multiple users, but the number of current paging users may be relatively small. At this time, the terminal also needs to perform blind detection of the length of the paging message in a group. Fig.9eThe position information occupied by different terminals on multiple time-division resources that are repeatedly sent remains unchanged, and this embodiment does not exclude certain jumps. Figure 9d~9e Only the repeated sending method corresponding to sending resource 0 is given. The corresponding methods for other sending resources (sending resource 1 to sending resource M-1) are similar and will not be given in detail here.

[0445] Example 3

[0446] This embodiment involves the problem of aggregation degree and the number of search spaces. In this embodiment, the public control information is sent on M time domain resources, each time domain resource includes N time domain symbols, and the public control information includes at least one of the following information: a public message, a public control signaling, wherein the public control signaling is used to indicate the relevant configuration information of the public message.

[0447] In a first implementation manner, each of the M time domain resources includes first-type public information, the first-type public information includes public control signaling and public messages, and the public control signaling indicates the sending of the public message. Figures 8a to 8c In the manner shown, the aggregation degree corresponding to the public control signaling at this time, and the number of candidate control channel resources under one aggregation degree L. The first manner is that in a time domain resource set, the coding rate of the public control information is fixed, the number of aggregation degrees corresponding to one public control information in the said one time domain resource is 1, the aggregation degree is fixed, that is, the number of time-frequency domain resources occupied by one public control signaling is fixed, and the number of candidate control channel resources included in one search space under each aggregation degree is 1, that is, there is only one candidate control channel under one aggregation degree, that is, the time-frequency resources occupied by the public control signaling are fixed. The second implementation method is: the aggregation degree corresponding to one public control information in the said one time domain resource, and / or the number of candidate control channel resources included in one search space under each aggregation degree, are determined by at least one of the following methods: the method of notifying the first-level public control information; the method of determining according to the system bandwidth; the method of determining according to the number of demodulation reference signal ports corresponding to one time domain resource. For example, if the aggregation level is {4 CCE, 8 CCE}, there are 2 candidate control channel resources corresponding to the aggregation level of 4 CCE, and there is 1 candidate control channel resource corresponding to the candidate control channel corresponding to the aggregation level of 8 CCE. The time-frequency resources corresponding to the candidate control channel resources under these two aggregation levels can overlap, reducing the complexity of terminal demodulation. CCE is a basic mapping unit similar to the control channel in LTE.

[0448] In the second implementation mode, each of the M time domain resources includes the second type of public control information, and the second type of public control information only includes public messages. That is, the public message is directly sent at this time, and there is no public control signaling. For direct transmission of public messages and the length of the public message may be variable, such as paging messages, the base station dynamically determines the transmission length of the paging message according to current needs, that is, the paging message may include the paging of one user or the paging of multiple users.

[0449] The common message is directly sent and it is assumed that the length of the common message is variable. In the first implementation, the terminal needs to perform blind detection in multiple common message lengths, and if the N values ​​included in each time domain resource corresponding to different lengths of the common message are different, the terminal needs to perform blind detection under multiple N value assumptions, that is, the terminal needs to perform blind detection on both (the N value included in each time domain resource, the common message length). Preferably, the blind detection range of the common message length is different for different N values. For example, when the N value is 1, the blind detection range of the common message length is length set 1 {length 1, length 2}, and when the N value is 2, the blind detection range of the common message length is length set 2 {length 3, length 4}. Preferably, the length of {length 3, length 4} is greater than {length 1, length 2}. Of course, this embodiment does not exclude the intersection of elements in length set 1 and length set 2. For example, if the common message is a paging message, the length at this time is the length before channel coding of the paging message, and the length before channel coding may cause the corresponding number of time-frequency resources occupied after channel coding to be different.

[0450] The second implementation method is to directly send a public message and assume that the length of the public message is variable. At this time, the search space of the user's paging message can be obtained according to the terminal identification number similar to the second embodiment. At this time, the resource utilization rate and the range of the terminal blind detection paging message length can be improved. Figure 9f As shown, multiple paging messages can be transmitted simultaneously on each time domain resource, and multiple users can be paged in one paging message. Multiple paging messages in one time domain resource are distinguished by different paging message detection ranges and paging message scrambling methods. For example, the detection range of the paging message and the scrambling method of the paging message are obtained according to the terminal identification number. For example, one paging opportunity corresponds to user 1 to user 40, and these users are divided into 4 groups {user 1 to user 10}, {user 11 to user 20}, {user 21 to user 30}, {user 31 to user 40}, and the 4 groups correspond to Figure 9f Paging message 0 to paging message 3 in Figure 9f The frequency domain resource corresponding to one paging message in the M time domain resources is fixed, and this embodiment does not exclude a hopping method in a certain manner, such as determining a search space for one paging message in one time domain resource according to a time domain resource index and a paging message index. Figure 9fDifferent paging messages in one time domain resource are frequency-divided. This embodiment does not exclude the overlap of detection spaces of different paging messages in the frequency domain. At this time, preferably, each paging message further has a blind detection of at least one of the following information: paging message length, paging message aggregation degree, and candidate control channel resources at each aggregation degree. One paging opportunity is composed of the M time domain resources. Of course, one paging opportunity can also appear periodically, but whether the public message is sent on the paging opportunity can be on demand, similar to a paging opportunity similar to a class of subframes determined by (PF, i_s) in LTE, and each subframe in this class of subframes corresponds to the M time domain resources here.

[0451] The third implementation method is to directly send a public message and assume that the length of the public message is variable. The paging message is divided into basic units, each unit includes a paging message and a control signaling, and the public signaling indicates at least one of the following information: whether the current unit is the last unit, the unit index of the current unit, the total number of units, the time-frequency domain resources where the following units are located, and a sub-block of the public message. Preferably, the number of bits corresponding to each basic unit is the same, so as to reduce the complexity of terminal blind detection.

[0452] Embodiment 4

[0453] The structure of the M*N time domain symbols described in the above embodiment is the logical result of these time domain symbols, and this embodiment describes the distribution of the physical positions of these time domain symbols. The first implementation method is that the M*N time domain symbols are in consecutive T1 subframes, and the M*N time domain symbols occupy the entire subframe in each subframe. For example, M*N=56, each subframe includes 14 time domain symbols, then 56 time domain symbols occupy 4 consecutive subframes, and occupy 14 time domain symbols in each subframe, that is, the symbols in each subframe are occupied by the time domain symbols that send public control information.

[0454] The second implementation method is that M*N time domain symbols occupy part of the time domain symbols in each subframe in consecutive T1 subframes, and do not occupy a full subframe. For example, M*N=56, each subframe includes 14 time domain symbols, then 56 time domain symbols occupy 8 consecutive subframes, and occupy 7 time domain symbols in each subframe, that is, the symbol part in each subframe is occupied by the time domain symbol for sending public control information. The remaining symbols can send general service data and proprietary control information.

[0455] The first implementation mode is that M*N time domain symbols occupy the entire subframe in each discrete T1 subframe, for example, M*N=56, each subframe includes 14 time domain symbols, then 56 time domain symbols occupy 4 discrete subframes, and each subframe occupies 14 time domain symbols, that is, the symbols in each subframe are occupied by the time domain symbols for sending public control information. The 4 discrete subframes are preferably equally spaced, or distributed according to a certain rule.

[0456] The second implementation method is that M*N time domain symbols occupy part of the time domain symbols in each subframe in discrete T1 subframes, and do not occupy a full subframe. For example, M*N=56, each subframe includes 14 time domain symbols, then 56 time domain symbols occupy 8 discrete subframes, and occupy 7 time domain symbols in each subframe, that is, the symbol part in each subframe is occupied by the time domain symbol for sending public control information. The remaining symbols can send general business data and proprietary control information. The discrete 8 subframes are preferably equally spaced, or distributed according to certain rules.

[0457] When the number of time domain symbols for transmitting public control information in a subframe is less than the number of time domain symbols included in the subframe, for example, the number of symbols allocated to the public control information in a subframe is less than the number of time domain symbols included in the subframe or all M time domain resources corresponding to the public control information do not occupy a subframe, the public control information in a subframe can be at the end of the downlink transmission domain of a subframe, such as Fig.10a As shown, or the common control information in a subframe is all in the starting downlink control field such as Fig.11a As shown, or part of the downlink control channel at the beginning of the subframe, part of it at the end of the downlink transmission domain, such as Fig.10b As shown, for example, M1 is the downlink control channel at the beginning of the subframe, and M2 is at the end of the downlink transmission domain. At this time, M1 time domain resources are all in the downlink control domain, or M1 time domain resources include the downlink control domain and the data transmission part, wherein the public control signaling in the M1 time domain resources is in the downlink control domain, and the public control signaling can indicate the time-frequency resources where the public message is located, wherein the public message can occupy the time-frequency resources in the data domain, such as Fig.10c shown.

[0458] for Fig.10b or Fig.10cIn the manner in [the above], for example, that is, among the M time-domain resources corresponding to the common control information to be transmitted in a subframe, there are M3 time-domain resources, where M = M3, or M3 < M, and the M3 transmission resource indices are known to the receiving end. M1 of the M3 are transmitted in the downlink control domain, and the remaining M2 are transmitted in the downlink transmission domain. The M1 transmission resource indices transmitted in the downlink control domain are dynamically variable and are transmitted as needed. The terminal first detects the M1 time-domain resources in the downlink control domain to determine the M1 transmission resources transmitted thereon. Each of the remaining M2 transmission resources is transmitted on M1 of the M2 resources.

[0459] Embodiment 5

[0460] In this embodiment, the transmission manner of the common information is determined according to the type of the common control information, or the transmission manner of the common control information is determined according to the number of symbols required by the common control information.

[0461] For example, the number of time-domain symbols required by the common control information is 14. For example, M = 14, N = 1, and the transmission manner of the common information can adopt the third transmission manner, as Fig.11a shown; or adopt the fourth transmission manner, as Fig.11b or Fig.11c shown. In Fig.11a the common message is indicated to be transmitted through the common control signaling. The common message can be frequency-division multiplexed with general service data. The common control signaling can be frequency-division multiplexed with the dedicated control signaling, similar to the manner of transmitting SIB / Paging / RAR / TPC in LTE. At this time, the structure of the subframe transmitting the common message is the same as that of the general subframe and does not require special processing. Preferably, the common message can be transmitted in any subframe. Fig.11b Or Fig.11c a dedicated set of time-domain symbols is adopted to transmit the common control information. Preferably, the dedicated control signaling and the common control signaling are time-division multiplexed. Preferably, the common message and the general service data are time-division multiplexed. At this time, the structure of the subframe transmitting the common message is different from that of the general subframe and requires special processing. Preferably, the common message can only appear in specific subframes and cannot appear in all subframes.

[0462] In this embodiment, one way is to determine whether to adopt the third transmission manner or the fourth transmission manner according to the number of time-domain symbols required by the common control information. For example, if the number of M*N is lower than a predetermined threshold, the third transmission manner is adopted; otherwise, the fourth transmission manner is adopted. The value of M can be determined according to the number of time-domain symbols of the synchronization signal, and further the value of N can be determined according to the size of the content of the common control information, so as to obtain the value of M*N, which is the number of time-domain symbols required by the common control information. The predetermined threshold is obtained according to the number of time-domain symbols included in the dedicated control channel.

[0463] Another method in this embodiment is to determine whether to use the third sending method or the fourth sending method according to the type of public control information. For example, when the delay requirement of the public message is relatively high, the third sending method is used, so that the public control is sent on demand in any subframe. For example, when the public message is RAR / TPC, the third sending method is used, and when the public message is a Paging / SIB message, the fourth sending method is used.

[0464] In this example, the method for sending the public control information is determined according to the type of public control information. It is also possible to determine whether the public control signaling indicates the sending of the public message or whether the public message is sent directly, based on whether the message length of the public control information is fixed or variable. For example, if the length is fixed, the public message is sent directly; if the length is variable, public control signaling is used to indicate the sending of the public message.

[0465] In this example, the method for sending the public control information is determined according to the type of public control information. It is also possible to determine whether the public control signaling indicates the sending of the public message or whether the public message is sent directly according to the message length of the public control information. For example, if the length is relatively small, the public message is sent directly, and if the length is relatively large, the public control signaling is used to indicate the sending of the public message.

[0466] In this example, the method for sending the public control information is determined according to the type of public control information. It is also possible to determine whether the public control information is sent on demand by public control signaling to indicate the sending of the public message or to send the public message directly. For example, when the public message is sent on a fixed basis, the public message is sent directly; when the public message is sent on demand, the public control signaling is used to indicate the sending of the public message.

[0467] In this example, the sending mode of the public control information is determined according to the type of the public control information. It can also be determined whether the public control signaling indicates the sending of the public message or directly sends the public message according to the delay requirement of the public control information. For example, the public message with a relatively small delay requirement adopts Fig.11b or Fig.11c The fourth sending method shown is used when the delay requirement is relatively large. Fig.11a The third transmission mode shown in FIG. 1 is used for transmission. When the time domain resources corresponding to the common control information are relatively large, the common control information is transmitted in multiple subframes. Fig.11a As shown. Fig.11a The public message requires 14 OFDM symbols, while there are only 2 OFDM symbols in the downlink control field in each subframe. The public control information needs to be sent in 7 subframes. Of course, if the number of time domain symbols required for the public control information is less than or equal to 2, the public control information can be sent in only one subframe. Fig.11a The number of time domain symbols required for the public control information is only an example and does not exclude other situations. Fig.11bThe public control information occupies one subframe, which is only an example and does not exclude other situations. Fig.11c The public control information only occupies the last 7 symbols of the downlink control field of a subframe. The number of symbols occupied is only an example and does not exclude other situations.

[0468] Embodiment 6

[0469] In this embodiment, for each N value, the terminal obtains the time domain symbol position where the time domain resource set is located, logically numbers these M*N time domain symbols 0,...M*N-1 in chronological order, and then the N time domain symbols included in each time domain resource are as follows.

[0470] The first implementation mode is that the N time domain symbols corresponding to the i-th transmission resource are logically numbered as: i*N+j, j=0,1,1, where 0≤i≤M-1;

[0471] A second implementation manner is that the N time domain symbols corresponding to the i-th transmission resource are M*n+i, where 0≤i≤M-1, 0≤n≤N-1.

[0472] Embodiment 7

[0473] In this embodiment, each of the M time domain resources includes a different number of time domain symbols.

[0474] For example, when public control information and proprietary control information are frequency-division multiplexed, different time domain resources require different time domain symbols. For example, some time domain resources contain proprietary control information, while some time domain resources do not.

[0475] The receiving method described in the present invention is one or more of the following methods: receiving beam, receiving port, receiving antenna, receiving time, receiving frequency domain, and the maximum number of receiving methods of the receiving end represents the number corresponding to different receiving methods used in receiving the same time domain resources.

[0476] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
