Description

Resource configuration method for control channel Technical field

The present invention relates to the field of communications, and in particular, to a control channel resource configuration method, a base station, and a terminal device.

Background technique

The Internet of Things (IoT) refers to the acquisition of information in the physical world by deploying various devices with certain sensing, computing, execution, and communication capabilities, and the realization of information transmission, coordination, and processing through the network, thereby realizing the interconnection of people, objects, and objects. The internet. In short, the Internet of Things is to achieve the interconnection of people and things, things and things. Possible applications include smart grid, smart agriculture, intelligent transportation, and environmental testing.

The 3rd Generation Partnership Project (3GPP) of the Mobile Communications Standardization Organization proposed the narrowband Internet of Things NB-IOT at the RAN#69 meeting. The downlink of NB-IoT is intended to use orthogonal frequency division multiple access OFDMA technology, while the uplink is intended to adopt single carrier frequency division multiple access SC-FDMA technology. In order to implement data transmission, the base station needs to send control information to the terminal through the control channel to indicate information such as time-frequency resources where the data transmission is located, and the terminal completes the downlink data on the indicated time-frequency resource by receiving the control information on the control channel. The reception or transmission of uplink data.

The control channel of NB-IoT supports multiple repetition times (ie 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048 repetitions) to meet different levels of coverage requirements. The NB-IoT allows the network side to send control information for different UEs with different repetition times, so that terminals under different fading levels can correctly receive control information.

In the prior art, the resource configuration of the control channel is as shown in FIG. 1, wherein FIG. 1(a) and FIG. 1(b) show the control channel resource configuration indicated by the network side for the terminal 1 and the terminal 2, respectively. In the prior art, the network side needs to indicate the number of repetitions of the control channel for the terminal. As shown in FIG. 1(a), the number of control channel repetitions configured by the network side for the terminal 1 is R=2, so that one transmission of the control channel will occupy two consecutive time units. In addition to the number of repetitions, the network side also needs to indicate a period factor G for the terminal so that the control channel can appear periodically at a certain time interval, so as to prevent the terminal from continuously monitoring the control channel continuously, thereby causing serious power consumption. The period T of the control channel is determined by the number of repetitions R and the periodic factor Sub G is determined jointly, ie:

T=R*G (1)

For all time units to be consecutively numbered in chronological order, the sequence number n of the starting time unit occupied by the control channel each time can be further determined as:

n mod T=0 (2)

As shown in FIG. 1(a), the network side configures the number of repetitions of the control channel R=2 and the period factor G=4, and the period of the control channel can be determined as T=8 according to formula (1), that is, The control channel of terminal 1 will appear every 8 time units. The sequence number of the start time unit occupied by each occurrence of the control channel is: 0, 8, 16, .... As shown in FIG. 1(b), the network side configures the number of repetitions of the control channel R=4 and the period factor G=4 for the terminal 2, and the period of the control channel can be determined as T=16 according to formula (1), that is, The control channel of terminal 1 will appear every 16 time units. The sequence number of the start time unit occupied by each occurrence of the control channel is: 0, 8, 16, ....

In the prior art, for any number of control channel repetitions configured for the terminal, the network side selects one cycle factor from the same cycle factor set, and then indicates the selected cycle factor together with the configured repetition number to the terminal. For a control channel configured with more repetitions, the system tends to configure some smaller periodic factors to avoid excessive transmission periods of the control channel, resulting in excessive communication delay. For a control channel configured with fewer repetitions, the system can configure a smaller period factor to obtain a shorter transmission period, thereby shortening the communication delay; the system can also configure a larger period factor to obtain a longer transmission period, thereby Reduce the terminal's monitoring of the control channel to save power. Based on the prior art, in order to implement the flexible period configuration described above, the periodic factor set needs to include a smaller period factor and a larger period factor, although for a different number of repetitions of the control channel, the system only configures a part of the period. factor. Therefore, in the prior art, the signaling overhead of the periodic factor configuration is large.

Summary of the invention

The embodiment of the invention provides a resource configuration method for a control channel:

The system defines at least two different sets of periodic factors, and maps each repetition quantity supported by the control channel to at least one periodic factor set, and requires that the set of periodic factors corresponding to at least two repetition times be different. The mapping relationship can be established by the network side or the terminal, Then, it is sent to the other party through signaling; it can also be predefined, so that no signaling interaction is required between the network side and the terminal.

In order to configure the control channel resource for the terminal, the base station first determines the repetition number of the control channel and determines the periodic factor set corresponding to the selected repetition number according to the mapping relationship between the repetition number and the periodic factor set, and then the base station selects the periodic factor from the periodic factor set. The base station transmits information indicating the number of repetitions of the control channel and/or information indicating the period factor to the terminal. The terminal receives information sent by the base station to indicate the number of repetitions of the control channel and/or information used to indicate the period factor.

Optionally, the terminal determines the period of the control channel and/or the location of the start time unit according to the received information indicating the number of repetitions of the control channel and/or information used to indicate the period factor.

In some scenarios, the system allows the base station to use multiple repetitions to transmit control channels to the terminal. For such a case, the embodiment of the present invention provides another resource configuration method for the control channel:

The system defines at least two different sets of periodic factors, and maps each maximum number of repetitions supported by the control channel to at least one set of periodic factors, and requires that at least two types of periodic factors corresponding to the maximum number of repetitions are different. of. The mapping relationship may be established by the network side or the terminal, and then sent to the other party through signaling. It may also be predefined, so that no signaling interaction is required between the network side and the terminal. The maximum number of repetitions is the maximum of the number of repetitions that can be used by the control channel.

In order to configure the control channel resource for the terminal, the base station first determines the maximum number of repetitions of the control channel and determines a set of periodic factors corresponding to the selected maximum number of repetitions according to the mapping relationship between the maximum number of repetitions and the periodic factor set, and then the base station selects from the set of periodic factors. Cycle factor. The base station transmits information indicating a maximum number of repetitions of the control channel and/or information indicating the period factor to the terminal. The terminal receives information sent by the base station to indicate the maximum number of repetitions of the control channel and/or information used to indicate the period factor.

Optionally, the terminal determines the period of the control channel and/or the location of the start time unit according to the received information indicating the maximum number of repetitions of the control channel and/or information used to indicate the period factor.

As shown in FIG. 1(a) and FIG. 1(b), the control channel resources of the terminal 2 always overlap with the control channel resources of the terminal 1, which causes the network side to only be able to overlap the control channel resources. One of the terminals sends control information, and the control information of the other terminal can only be delayed. Therefore, there are many limitations in practical applications. Therefore, the present invention also provides another optimized resource allocation method for the control channel:

The base station determines a starting position offset or a starting position offset indicating parameter. The base station sends the start position offset or start position offset indication parameter to the terminal. The terminal receives the message sent by the base station and determines the location of the start time unit of the control channel.

The functions may be implemented by hardware or by corresponding software implemented by hardware. The hardware or software includes one or more modules corresponding to the functions described above.

The transmitter is configured to support communication between the base station and the UE, and send information or instructions involved in the foregoing method to the UE. The base station can also include a memory for coupling with the processor that stores the necessary program instructions and data for the base station.

The embodiment of the invention provides a terminal device, which has the function of realizing the behavior of the terminal device in the design of the above method. The functions may be implemented by hardware or by corresponding software implemented by hardware. The hardware or software includes one or more modules corresponding to the functions described above. The modules can be software and/or hardware.

In a possible design, the structure of the terminal device includes a receiver and a processor, the receiver is configured to receive control channel resource configuration information sent by the base station, and the processor is configured to use the control channel resource received by the receiving module. The configuration information determines the period of the control channel and the location of the start time unit.

Compared with the prior art, the solution provided by the present invention will have different repetition times and different periodic factors. The set establishes a correspondence, so that the flexibility of the control channel resource configuration can be improved without increasing the signaling overhead, for example, the smaller number of repetitions is associated with a set of periodic factors with larger element values, and larger The number of repetitions is associated with a set of periodic factors with smaller elements. By repeating the number of repetitions and the configuration of the periodic factors, the control channel with a smaller number of repetitions obtains a larger period, and the control channel with a larger number of repetitions is smaller. cycle. In addition, the solution provided by the invention reduces the resource collision probability between two control channels configured with different repetition times and periodic factors by configuring a starting position offset or a starting position offset parameter, thereby avoiding communication delay Increase.

It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present invention and the above figures are used to distinguish similar objects without having to use To describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

The present invention is mainly applied to a Long Term Evolution (LTE) system or an Advanced Long Term Evolution (LTE-A) (LTE Advanced) system. In addition, the present invention can also be applied to other communication systems as long as there are entities in the communication system that can transmit information, and other entities can receive information.

As shown in FIG. 2, the base station and the terminal device 1 to the terminal device 6 constitute a communication system in which the base station and the terminal device 1 to the terminal device 6 can transmit data to each other. Further, the terminal device 4 to the terminal device 6 also constitute a communication system in which the terminal device 5 can transmit information to one or more of the terminal device 4 and the terminal device 6.

Although the LTE system is taken as an example in the foregoing background, the person skilled in the art should know that the present invention is not only applicable to the LTE system, but also applicable to other wireless communication systems, such as the Global System for Global System (Global System for Mobile System). Mobile Communication, GSM), Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access (CDMA) system, and new network systems. The following describes an embodiment of the LTE system as an example.

The terminal device according to the embodiment of the present invention may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN), which can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it may be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges language and/or data with a wireless access network. For example, Personal Communication Service (PCS), cordless phones, Session Initiation Protocol (SIP) phones, wireless local loops (WLL, Wireless Local) Loop) stations, personal digital assistants (PDAs, Personal Digital Assistant) and other devices. A wireless terminal may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, or an access point. Remote Terminal, Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

In existing LTE systems, the Enhanced Machine Type Communication (eMTC) function supports different repetition times of control channel transmission. The network side needs to perform resource configuration on the control channel, and then sends relevant configuration information to the terminal, so that the terminal can accurately know the resource location of the control channel. In eMTC, according to the channel condition in which the terminal is located, the network side selects an appropriate number of control channel repetition times for the terminal; then, selects a period factor in a set of period factors; finally, selects the selected channel repetition number and period factor as Control channel resource configuration parameters are sent to the terminal. After receiving the control channel resource configuration parameter, the terminal may determine the number of repetitions used by the network side to send the control channel for the terminal, and determine the period of the control channel and all the times by the repetition number and the period factor according to formula (1) and formula (2). The sequence number of the start time unit.

The above resource configuration method has the following problem: for any number of control channel repetitions configured for the terminal, the network side selects one period factor from the same period factor set, and then indicates the selected period factor together with the configured repetition number. Give the terminal. For a control channel configured with more repetitions, the system tends to configure some smaller periodic factors to avoid excessive transmission periods of the control channel, resulting in excessive communication delay. For a control channel configured with fewer repetitions, the system can configure a smaller period factor to obtain a shorter transmission period, thereby shortening the communication delay; the system can also configure a larger period factor to obtain a longer transmission period, thereby Reduce the terminal's monitoring of the control channel to save power. Based on the prior art, in order to implement the flexible period configuration described above, the periodic factor set needs to include a smaller period factor and a larger period factor, although for a different number of repetitions of the control channel, the system only configures a part of the period. factor. Therefore, in the prior art, the signaling overhead of the periodic factor configuration is large.

In a first embodiment, the system defines at least two different sets of periodic factors, and maps each repetition number to at least one periodic factor set, requiring at least 2 repetitions. The corresponding set of periodic factors is different. The mapping relationship may be established by the network side or the terminal, and then sent to the other party through signaling. It may also be predefined, so that no signaling interaction is required between the network side and the terminal. Based on the mapping relationship, FIG. 3 provides a schematic flowchart of an information indication method, including:

301. The base station determines the number of repetitions of the control channel.

302. The base station determines, according to a mapping relationship between the number of repetitions and the set of periodic factors, a set of periodic factors corresponding to the selected number of repetitions.

303. The base station selects a periodic factor from the set of periodic factors.

304. The base station sends, to the terminal, information used to indicate the number of repetitions of the control channel and/or information used to indicate the period factor.

305. The terminal determines, according to the information used to indicate the repetition quantity of the control channel and/or the information used to indicate the period factor, the period of the control channel and/or the location of the start time unit.

As a first example, the system may define two sets of periodic factors, wherein the values of the elements in the first set of periodic factors are greater than the values of the elements in the second set of periodic factors. A plurality of smaller repetitions are mapped to the first periodic factor set, and a remaining larger number of repetitions is mapped to the second periodic factor set. Thus, for a control channel with fewer repetitions, the network side has a larger period by selecting a larger period factor.

As a second example, the system may define a plurality of periodic factor sets, and each of the repetition times is respectively mapped to one of the periodic factor sets, as shown in Table 1.

Table 1 Mapping between the number of repetitions and the set of periodic factors

Number of repetitions R	Cycle factor set {g 0 ,g 1 ,...}

The terminal receives information sent by the base station to indicate the number of repetitions of the control channel and/or information used to indicate the period factor to determine a period of the control channel and/or a location of the start time unit. As an example, the period T of the control channel can be determined as follows:

T=R*G (3)

According to the mapping relationship between the number of repetitions and the period factor shown in Table 1, Table 2 gives the total period values calculated according to the formula (3). All time units are consecutively numbered in chronological order, then the start time unit position of the control channel can be determined by the sequence number n of the time unit, as determined by:

n mod T=0 (4)

Table 2 Cycles obtained by the number of repetitions and the period factor

In some scenarios, the system allows the base station to use multiple repetitions to transmit control channels to the terminal. For such a case, the present invention gives a second embodiment. In the second embodiment, the maximum of the plurality of repetition times available for the control channel is defined as the maximum number of repetitions. For different terminals, the base station can configure different maximum repetition times for the control channel, and then the base station can only use the repetition number that does not exceed the maximum number of repetitions to send a control channel to the terminal. The system defines at least two different sets of periodic factors, and maps each of the maximum number of repetitions to at least one set of periodic factors, and requires that at least two of the maximum number of repetitions correspond to different sets of periodic factors. The mapping relationship may be established by the network side or the terminal, and then sent to the other party through signaling. It may also be predefined, so that no signaling interaction is required between the network side and the terminal. Based on the mapping relationship, FIG. 3 provides a schematic flowchart of an information indication method, including:

401. The base station determines a maximum number of repetitions of the control channel.

402. The base station determines, according to a mapping relationship between the maximum number of repetitions and the set of periodic factors, a set of periodic factors corresponding to the selected maximum number of repetitions.

403. The base station selects a period factor from the set of period factors.

404. The base station sends, to the terminal, information used to indicate a maximum number of repetitions of the control channel and/or information used to indicate the period factor.

405. The terminal determines a period of the control channel and/or a location of the start time unit according to the information used to indicate the maximum number of repetitions of the control channel and/or the information used to indicate the period factor.

As a first example, the system may define two sets of periodic factors, wherein the values of the elements in the first set of periodic factors are greater than the values of the elements in the second set of periodic factors. Will have a small number of values The maximum number of repetitions is mapped to the first periodic factor set, and the remaining maximum number of repetitions is mapped to the second periodic factor set. Thus, for a control channel with a small maximum number of repetitions, the network side has a larger period by selecting a larger period factor.

As a second example, the system may define a plurality of periodic factor sets, and each of the maximum repetition times is respectively mapped to one of the periodic factor sets, as shown in Table 1.

Table 1 Mapping of the maximum number of repetitions and the set of periodic factors

The terminal receives information sent by the base station to indicate the maximum number of repetitions of the control channel and/or information used to indicate the period factor to determine the period of the control channel and/or the location of the start time unit. As an example, the period T of the control channel can be determined as follows:

T=R*G (3)

According to the mapping relationship between the maximum number of repetitions and the period factor shown in Table 1, Table 2 gives the total period values calculated according to the formula (3). All time units are consecutively numbered in chronological order, then the start time unit position of the control channel can be determined by the sequence number n of the time unit, as determined by:

n mod T=0 (4)
