Description

Transmission method, device, base station and terminal for paging information
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, a base station, and a terminal for transmitting paging information.
Background
With the continuous progress of radio technology, various radio services are greatly emerged, and the spectrum resources supported by the radio services are limited, so that in the face of the continuous increase of bandwidth requirements, the spectrum resources between 300MHz and 3GHz mainly used by the traditional commercial communication show a very tight situation, and the requirements of future wireless communication cannot be met.
In future wireless communication, a carrier frequency higher than that used by a fourth generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, 70GHz, and the like, and such a high-frequency channel has the disadvantages of large free propagation loss, easy absorption by oxygen, large influence by rain attenuation, and the like, and seriously affects the coverage performance of the high-frequency communication system. However, since the carrier frequency corresponding to the high-frequency communication has a shorter wavelength, it is ensured that more antenna elements can be accommodated in a unit area, and more antenna elements mean that a beamforming method can be adopted to increase the antenna gain, thereby ensuring the coverage performance of the high-frequency communication.
After the beam forming method is adopted, the transmitting end can concentrate the transmitting energy in a certain direction, and the energy in other directions is little or no, that is, each beam has own directivity, each beam can only cover the terminal in a certain direction, and the transmitting end, namely the base station, needs to transmit the beam in dozens or even hundreds of directions to complete the all-round coverage.
In a new generation radio access technology (NR, new RAT), a User Equipment (UE) in an IDLE state needs to monitor paging, and monitors paging information only at a specific paging time using a Discontinuous Reception (DRX) mechanism. At the paging time, the terminal needs to further check whether paging information exists, and needs to determine information such as a frequency domain position, a modulation coding mode and the like of the paging information, so as to complete the reception of the paging information. In the existing schemes in the industry, information such as frequency domain resource location, modulation and coding scheme, etc. of paging information is indicated through paging control signaling, where the paging control information is sent in a beam scanning manner. In the above existing solutions in the industry, on one hand, the paging control signaling occupies more resources due to the beam scanning mode of the paging control information. On the other hand, the terminal needs to blindly detect the paging control information, resulting in higher detection complexity and more power consumption. Therefore, it is an urgent problem in the art to provide a method that can not only save resource occupancy, but also further reduce the detection complexity of the terminal and save power consumption.

Detailed Description
The present invention will be described in further detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Example one
The present embodiment provides a transmission method of paging information performed on the base station side. Fig. 1 is a flowchart of a transmission method of paging information according to a first embodiment of the present invention.
Step S110, dividing the information in the paging information into a plurality of preset packets.
In this embodiment, the information in the paging information includes common paging information and/or dedicated paging information (dedicated paging information is also called terminal-specific paging information). In this embodiment, the paging information does not include scheduling information (scheduling signaling).
The public paging information is as follows: paging information transmitted to a plurality of terminals within the coverage of a base station.
The special paging information is: paging information transmitted to a terminal within the coverage of the base station.
The types of packets include: a common paging information packet and a dedicated paging information packet.
Dividing all public paging information in the paging information into one or more preset public paging information groups according to a preset grouping rule; and dividing all the special paging information in the paging information into one or more preset special paging information groups according to a preset grouping rule.
The grouping rules record the way in which information in the paging information is divided into groups.
For example: determining a public paging information group corresponding to the public paging information according to the type of each public paging information; and then dividing the public paging information into corresponding public paging information groups.
For another example: determining a special paging information group corresponding to the special paging information according to the identifier and/or the time index of the terminal corresponding to each special paging information; or, according to the information and/or time index obtained by the terminal corresponding to each dedicated paging information, determining the dedicated paging information packet corresponding to the dedicated paging information; and the dedicated paging information is classified into a corresponding dedicated paging information packet. The information obtained by the terminal comprises: information obtained during the last initial network access or after the last network access.
Step S120, performing modulation coding on each of the plurality of packets.
And respectively carrying out modulation coding on the plurality of groups according to a preset modulation coding mode. Further, the plurality of packets are modulation-coded according to modulation-coding methods corresponding to the plurality of packets, respectively.
The same modulation and coding scheme may be used for a plurality of packets, or different modulation and coding schemes may be used for a plurality of packets. For example: the same modulation coding mode is adopted between the public paging information groups, the same modulation coding mode is adopted between the special paging information groups, and different modulation coding modes are adopted between the public paging information groups and the special paging information groups.
Step S130, mapping the plurality of groups to different frequency domain resource positions, respectively.
And respectively mapping the groups to different frequency domain resource positions by adopting a preset resource mapping rule.
The resource mapping rule comprises: the number (quantity) of frequency domain resources corresponding to each public paging information group is fixed, and the frequency position of the starting frequency domain position corresponding to each public paging information group from the center of the carrier wave is a fixed distance value; each dedicated paging information packet corresponds to a fixed number of frequency domain resources and a fixed starting frequency domain location. Therefore, according to the frequency domain resource number and the initial frequency domain position corresponding to the grouping divided with the information in the paging information, the frequency domain resource position finally mapped by the grouping can be determined.
The types of frequency domain resource locations include: a physical frequency domain resource location and a logical frequency domain resource location. The resource mapping rule further includes: and the corresponding relation between the physical frequency domain resource position and the logical frequency domain resource position.
And mapping each group to a physical frequency domain resource position by adopting a preset resource mapping rule, or mapping each group to a logic frequency domain resource position, and then mapping the logic frequency domain resource position of each group to a corresponding physical frequency domain resource position.
Step S140 is to transmit the plurality of packets to the terminal side at the paging time.
At the paging time, a plurality of packets are transmitted to the terminal side by a predetermined transmission method.
In this embodiment, the preset sending method is as follows: a beam scanning transmission mode, a single frequency network transmission mode, a repeated omni-directional transmission mode, or a space-frequency block code transmission mode.
Multiple packets may be repeatedly transmitted within one or more paging time blocks within a paging time interval. One or more paging time blocks that may be used to transmit a plurality of packets are determined within a paging time interval, and the plurality of packets are transmitted at paging occasions of the paging time blocks used to transmit the plurality of packets.
A diagram of the paging interval shown in fig. 2. In fig. 2, two paging intervals are shown, each of which includes 6 paging time blocks, and if each of the paging time blocks has a paging occasion, it is necessary to repeatedly transmit a plurality of packets to the terminal side 6 times at each of the paging time intervals.
In this embodiment, at different paging occasions, the same or different transmission manners may be used, and the transmission manners include but are not limited to: a beam scanning transmission mode, a single frequency network transmission mode, a repeated omnidirectional transmission mode and a space-frequency block code transmission mode.
Before transmitting a plurality of packets, a frequency domain signal including the plurality of packets is converted into a time domain signal and then transmitted to a terminal side.
Specifically for step S110:
the number of the common paging information packets may be a fixed value set in advance; the number of dedicated paging information packets may be a fixed value set in advance, or a value configured in advance through higher layer signaling and/or physical layer signaling. In this way, the information in the paging information is divided into a plurality of preset packets, and the information in the paging information may be divided into only a part of the packets in the total packet amount.
The higher layer signaling is, for example, radio Resource Control (RRC) signaling.
The Physical layer signaling is, for example, physical Downlink Control Channel (PDCCH) signaling.
According to a preset grouping rule, a public paging information group corresponding to the public paging information and a special paging information group corresponding to the special paging information can be determined. And dividing the public paging information into corresponding public paging information groups, and dividing the special paging information into corresponding special paging information groups.
In the embodiment, each public paging information packet comprises one or more first domains, and each first domain corresponds to a type of public paging information; each dedicated paging information packet includes one or more second domains, each second domain corresponding to a terminal. Further, each common paging information packet includes a plurality of first domains ordered by a type of the common paging information. Each of the first fields and each of the second fields corresponds to a predetermined number of bits.
Dividing common paging information in paging information into corresponding common paging information groups according to types, and enabling the common paging information to correspond to a first domain corresponding to the types; the special paging information in the paging information is classified into a special paging information packet, and the terminal corresponding to the special paging information corresponds to a second domain in the special paging information packet. The dedicated paging information packet corresponds to a terminal to which the dedicated paging information corresponds.
If a first domain which does not correspond to the public paging information exists in the public paging information packet, carrying out bit filling on the first domain; and if the second domain without the corresponding terminal exists in the special paging information packet, carrying out bit filling on the second domain. That is, only a part of the fields (the first field or the second field) in the packet has corresponding information, and then the remaining fields in the packet are made to correspond to the padding bits.
The bit filling method comprises the following steps: in a packet (common paging information packet or dedicated paging information packet), a predetermined number of bit values are set, which may be set to all zeros, to all 1's, or to a fixed sequence of bits.
Specifically for step S120:
and modulating and coding and mapping frequency domain resource positions only for the packets needing to be transmitted to the terminal in a preset plurality of packets. That is, among the preset plurality of packets, if only a part of the packets are divided by the information in the paging information or only a part of the packets divided by the information in the paging information need to be transmitted to the terminal, modulation coding for the remaining part of the packets and mapping of the frequency domain resource location are prohibited.
In the preset plurality of groups, in the frequency domain resource positions corresponding to other groups except the group needing to be sent to the terminal, all or part of the frequency domain resource positions are used for bearing other information except the paging information, or all the frequency domain resource positions are not used for bearing other information except the paging information.
In other words, modulation coding and mapping of frequency domain resource locations are not performed for packets that are not divided into information in paging information and packets that are not required to be transmitted to a terminal that are already divided into information in paging information. After dividing the information in the paging information into each group, determining the group which needs to be transmitted to the terminal, and performing modulation coding and frequency domain resource mapping only on the group which needs to be transmitted to the terminal, and performing no modulation coding, mapping no frequency domain resource position and transmitting to the terminal side. Since these groups are not modulated and coded, nor mapped with frequency domain resource positions, these unoccupied frequency domain resource positions can be used to carry other information, or these unoccupied frequency domain resource positions can not carry other information. In high frequency wireless communication, in order to compensate for the characteristic of high frequency channel attenuation, it is necessary to introduce a mechanism such as beam scanning of paging information or multiple retransmissions of paging information. In addition to the paging information itself requiring beam scanning or multiple retransmissions, the control information used to schedule the paging information also requires beam scanning or multiple retransmissions. Therefore, the radio resource overhead occupied by the control signaling (scheduling information) for scheduling the paging information cannot be ignored. In addition, the terminal needs to blindly detect the paging control signaling, resulting in higher detection complexity and more power consumption. The paging method of the embodiment of the invention can not only avoid the resource overhead of the paging control signaling, but also reduce the detection complexity of the terminal and achieve the aim of saving the terminal.
Example two
The present embodiment provides a transmission method of paging information performed on the terminal side. Fig. 3 is a flowchart of a transmission method of paging information according to a second embodiment of the present invention.
Step S310, determining a packet corresponding to the terminal.
The types of packets include: a common paging information packet and a dedicated paging information packet.
The common paging information packet is used to transmit common paging information to a plurality of terminals within the coverage area of the base station.
The dedicated paging information packet is used to transmit dedicated paging information to a terminal within the coverage area of the base station.
The common paging information groups are all used as groups corresponding to the terminals, and the special paging information groups corresponding to the terminals are determined according to a preset grouping rule; or, according to a preset grouping rule, determining a public paging information group and a special paging information group corresponding to the terminal. The grouping rule on the terminal side corresponds to the grouping rule used on the base station side. For example: before paging, the base station transmits a grouping rule to the terminal so that the base station and the terminal use the same grouping rule.
Specifically, the number of the common paging information packets is a fixed value preset at the base station side; the number of dedicated paging information packets is a fixed value preset at the base station side or a value pre-configured at the base station side through higher layer signaling and/or physical layer information. This requires determining which of a plurality of dedicated paging information packets is sent to the terminal for targeted reception by the terminal. .
For example: before detecting a packet sent by a base station, a terminal determines a special paging information packet corresponding to the terminal according to an identifier and/or a time index of the terminal; or, according to the information and/or time index obtained by the terminal, determining the special paging information group corresponding to the terminal; the information obtained by the terminal comprises: information obtained during the last initial network access or after the last network access.
Step S320, determining the frequency domain resource location mapped by the group corresponding to the terminal.
And determining the frequency domain resource position of the grouping mapping corresponding to the terminal by adopting a preset resource mapping rule.
The resource mapping rule of the terminal side corresponds to the resource mapping rule used by the base station side. For example: before paging, the base station sends the resource mapping rule to the terminal, so that the base station and the terminal use the same resource mapping rule.
Since the number of the common paging information packet and the dedicated paging information packet are preset or configured, when the resource mapping rule is set, the resource mapping rule may include: each public paging information group corresponds to a fixed frequency domain resource number, and the frequency position of the starting frequency domain position corresponding to each public paging information group from the center of the carrier wave is a fixed distance value; each dedicated paging information packet corresponds to a fixed number of frequency domain resources and a fixed starting frequency domain position. Thus, after the grouping corresponding to the terminal is determined, the frequency domain resource position finally mapped by the grouping can be determined according to the frequency domain resource number corresponding to the grouping and the initial frequency domain position.
The types of frequency domain resource locations include: physical frequency domain resource location and logical frequency domain resource location. The resource mapping rule further includes: the correspondence of physical frequency domain resource locations and logical frequency domain resource locations,
determining a physical frequency domain resource position or a logical frequency domain resource position of the grouping mapping corresponding to the terminal by adopting a preset resource mapping rule; and if the frequency domain resource position of the grouped mapping is determined to be a logic frequency domain resource position, mapping the logic resource position into a physical frequency domain resource position according to the resource mapping rule.
Step S330, at the paging time, in the frequency domain resource position, detecting the packet sent by the base station.
In this embodiment, the terminal uses a discontinuous reception mechanism to detect the packet sent by the base station at the paging time and in the frequency domain resource location according to a preset demodulation and decoding manner. Further, the terminal may determine the paging occasion based on information obtained from base station higher layer signaling and/or physical layer signaling.
The demodulation decoding method used by the terminal side corresponds to the modulation coding method used by the base station side.
Performing cyclic redundancy check on the packet; determining that the packet was successfully detected if the cyclic redundancy check is passed; if the cyclic redundancy check is not passed, determining that the packet is not transmitted by the base station at the frequency domain resource location, or determining that the packet is not successfully detected.
When receiving the time domain signal containing the packet, the time domain signal is firstly converted into a frequency domain signal, and the packet is demodulated, decoded and checked by cyclic redundancy.
Step S340, in the successfully detected packet, obtaining information corresponding to the terminal, where the information is information in the paging information.
The information in the paging information includes common paging information and/or dedicated paging information.
The terminal needs to obtain all public paging information and dedicated paging information corresponding to the terminal, so that the information corresponding to the terminal may be considered to include: the public paging information and the special paging information corresponding to the terminal.
And acquiring the public paging information in the successfully detected public paging information packet, and acquiring the special paging information corresponding to the terminal in the successfully detected special paging information packet.
In this embodiment, each common paging information packet includes one or more first domains, each corresponding to a type of common paging information; each dedicated paging information packet includes one or more second domains, each second domain corresponding to a terminal. Further, each common paging information packet includes a plurality of first domains ordered by a type of the common paging information.
In the successfully detected public paging information packet, acquiring the public paging information of the type according to the type corresponding to each first domain; and in the successfully detected special paging information packet, acquiring the special paging information corresponding to the terminal according to the second domain corresponding to the terminal. Further, in the successfully detected common paging information packet, the common paging information of the type corresponding to each first domain may be sequentially acquired according to the type sorting order of the common paging information.
In this embodiment, in order to avoid that the common paging information is a padding bit, the bit value corresponding to each first field needs to be queried in the successfully detected common paging information packet, so as to determine whether the bit value corresponding to the first field is a padding bit. For example: and if the bit value corresponding to the first domain is all zeros, all 1 or a fixed bit sequence, the bit value corresponding to the first domain is considered as a filling bit instead of the public paging information.
The paging information is grouped, the scheduling information does not need to be used for informing the terminal which information in the paging information is sent to the terminal, the problem of high resource cost is avoided, the terminal can directly find the required information in each group by sending the information to the terminal in a grouping mode, blind detection of call control information is not needed, the problems of high detection complexity and high power consumption are further avoided, and the paging efficiency is improved.
The process of paging the terminal by the base station and the grouping process of the paging information are further described below by several embodiments.
EXAMPLE III
In the present embodiment, the paging information includes common paging information. The base station presets a fixed number of a plurality of common paging information packets.
Fig. 4 is a flowchart of steps for a base station to page a terminal according to a third embodiment of the present invention.
Step S410, the base station divides the public paging information in the paging information into the corresponding public paging information groups according to the types, and makes the public paging information correspond to the first domain corresponding to the types.
The types of common paging information are, for example: warning information, system messages, etc.
A plurality of common paging information groups are predefined, each common paging information group comprises one or more first domains, and each first domain corresponds to a type of common paging information. The number of bits per first field is fixed. Further, it is predefined that each common paging information packet includes a plurality of first domains ordered according to the type of the common paging information. That is, the type of common paging information included in each common paging information packet, and the arrangement order of the different types of common paging information are predefined. The plurality of common paging information packets correspond to different types of common paging information, respectively.
Determining the type of public paging information in the paging information, inquiring a public paging information packet corresponding to the type, dividing the public paging information into the public paging information packet, wherein the public paging information packet comprises a first domain corresponding to the type of the public paging information, and after dividing the public paging information into the public paging packet, enabling the public paging information to correspond to the first domain.
In this embodiment, all the common paging information packets are classified into the common paging information, and all the first domains in each common paging information have corresponding common paging information.
Of course, if there is a first field in the common paging information packet that does not correspond to the common paging information, the first field is made to correspond to the padding bits.
Step S420, the base station modulates and codes each public paging information packet, and maps a plurality of public paging information packets to different frequency domain resource positions.
The multiple common paging information packets may use the same or different modulation and coding schemes.
After modulating and coding a plurality of public paging information groups, respectively mapping the plurality of public paging information groups to different frequency domain resource positions according to a preset resource mapping rule. Further, inquiring the frequency domain resource number corresponding to each public paging information group and the distance value of the initial frequency domain position of the public paging information group relative to the frequency position of the carrier center; and mapping the common paging information group according to the fixed frequency domain resource number and the fixed distance value.
For example: presetting N public paging information groups, and predefining the frequency domain M occupied by the nth public paging information group n Physical resource block (fixed frequency domain resource number), frequency position L of starting frequency domain position from carrier center n Physical resource blocks (fixed distance values). N, N, M n And L n Are integers, and N is more than or equal to 1 and less than or equal to N. As shown in fig. 5, N is 3, and each common paging information packet is based on the number of physical resource blocks occupied by it and the number of physical resource blocks at the frequency position away from the center of the carrierQuantities, mapped to respective frequency resource locations.
Step S430, the base station converts the frequency domain signal containing a plurality of public paging information packets into a time domain signal and sends the time domain signal to the terminal side at the paging time.
Step S440, the terminal receives the time domain signal sent by the base station at the paging time, and converts the time domain signal into a frequency domain signal.
Step S450, the terminal demodulates and decodes each public paging information packet at the frequency domain resource position mapped by each public paging information packet, and performs cyclic redundancy check on each public paging information packet.
The terminal and the base station adopt the same resource mapping rule, and the frequency domain resource position mapped by the public paging information packet can be determined according to the frequency domain resource number corresponding to each public paging information packet and the distance value of the initial frequency domain position of the public paging information packet relative to the frequency position of the carrier center.
The demodulation decoding adopted by the terminal corresponds to the modulation coding mode adopted by the base station.
In step S460, the terminal determines the common paging information packet passing the cyclic redundancy check as a successfully detected common paging information packet.
After demodulating and decoding the public paging information packet received by the frequency resource position, performing cyclic redundancy check on the public paging information packet, and determining that the public paging information packet which does not pass the cyclic redundancy check is not sent by the base station at the frequency domain resource position or determining that the public paging information packet is not successfully detected.
Step S470 is that the terminal acquires the type of the public paging information according to the type of the public paging information corresponding to each first domain in the successfully detected public paging information packet.
Since each common paging information packet comprises a plurality of first domains ordered according to the types of the common paging information, in each common paging information packet, the common paging information of the corresponding type of each first domain can be acquired according to a plurality of orders ordered according to the types of the common paging information.
And inquiring the bit value corresponding to each first domain in the successfully detected common paging information packet so as to determine whether the bit value corresponding to the first domain is a filling bit.
Example four
In this embodiment, the paging information includes common paging information. The base station presets a fixed number of a plurality of common paging information packets.
Fig. 6 is a flowchart of steps for a base station to page a terminal according to a fourth embodiment of the present invention.
Step S610, the base station divides the public paging information in the paging information into the corresponding public paging information groups according to the type, and makes the public paging information correspond to the first domain corresponding to the type.
In the present embodiment, only part of the common paging information packets among the plurality of common paging information packets into which the common paging information is classified need to be transmitted to the terminal, that is, only part of the common paging information needs to be transmitted to the terminal side.
Further, when the common paging messages corresponding to different common paging message packets have different transmission frequencies, only part of the common paging messages may be transmitted at a part of the paging occasions (so that the remaining packets do not need to be transmitted), and the remaining common paging messages may be transmitted at the remaining paging occasions.
For example, there are two common paging information packets, and the common paging information corresponding to the common paging information packet 1 is sent once every 100ms (e.g., 1ms,101ms,201ms,. Uplink); the public paging information corresponding to the public paging information group 2 is sent once every 200ms (for example, 1ms,201ms, 401ms.. Upward); the transmission frequency of the common paging information packet 1 is low so that the common paging information packet 2 does not need to be transmitted at the 101 ms.
Step S620, the base station modulates and codes a part of the common paging information packets to be transmitted, and maps the part of the common paging information packets to different frequency domain resource locations.
And the part of the common paging information packet which does not need to be transmitted is not modulated and coded, and is not mapped to the frequency domain resource position.
For example: n public paging information groups are preset, the N public paging information groups are all divided into public paging information, wherein x (x is more than or equal to 1 and less than or equal to N) public paging information groups do not need to be sent to a terminal side, N-x public paging information groups need to be sent to the terminal side, and then only N-x public paging information groups are modulated and coded and mapped to corresponding frequency domain resource positions. As shown in fig. 7, where N is 3, x is 1, the first and third common paging information packets are mapped to corresponding frequency domain resource locations, and the second common paging information packet that is not required to be transmitted to the terminal side is not mapped to the corresponding frequency domain resource locations.
Step S630, the base station converts the frequency domain signal containing the part of the common paging information packet into a time domain signal and sends the time domain signal to the terminal side at the paging time.
Step S640, the terminal receives the time domain signal sent by the base station at the paging time, and converts the time domain signal into a frequency domain signal.
Step S650, the terminal demodulates and decodes each public paging information packet at the frequency domain resource position mapped by each public paging information packet, and performs cyclic redundancy check on each public paging information packet.
For example: the terminal sends N-x frequency domain resource positions of the public paging information packets at the base station, and the terminal considers that the N-x public paging information packets are successfully detected through cyclic redundancy check.
For another example, the terminal cannot pass the paging redundancy check at the N-x frequency domain resource locations where the base station sent the common paging information packet, and the terminal considers that the base station sent the x common paging information packets but did not successfully detect the common paging information packets, or the terminal considers that the base station did not send the x common paging information packets.
For another example, the terminal cannot pass the paging redundancy check at x frequency-domain resource locations where the base station does not transmit the common paging information packet, and the terminal considers that the base station transmits the x common paging information packets but does not successfully detect the x common paging information packets, or the terminal considers that the base station does not transmit the x common paging information packets.
And step S660, determining the common paging information packet passing the cyclic redundancy check as the successfully detected common paging information packet.
Step S670, in the successfully detected common paging information packet, obtaining the common paging information of the type according to the type corresponding to each first domain.
EXAMPLE five
In the present embodiment, the paging information includes common paging information. The base station presets a fixed number of a plurality of common paging information packets.
Fig. 8 is a flowchart of steps for a base station to page a terminal according to a fifth embodiment of the present invention.
Step S810, the base station divides the common paging information in the paging information into corresponding common paging information groups according to types, and makes the common paging information correspond to a first domain corresponding to the types.
In this embodiment, only a part of the common paging information packets among the plurality of common paging information packets into which the common paging information is classified need to be transmitted to the terminal side.
Step S820, the base station modulates and codes a part of the common paging information packets to be transmitted, and maps the part of the common paging information packets to different frequency domain resource locations.
Step S830, the base station uses all or part of the frequency domain resource locations to carry other information in the frequency domain resource locations to which the part of the common paging information packets that need not be sent should be mapped.
According to the predefined frequency domain resource mapping rule, the frequency domain resource position corresponding to the public paging information packet which does not need to be sent can be determined.
The other information is, for example, physical downlink data.
For example: n public paging information groups are preset, the N public paging information groups are all divided into public paging information, wherein x (x is more than or equal to 1 and less than or equal to N) public paging information groups do not need to be sent, and in frequency domain resource positions corresponding to the x public paging information groups, all or part of the frequency domain resource positions are used for sending physical downlink data except the paging information.
If the base station carries the physical downlink data at the frequency domain resource position mapped by the part of the common paging information packets which do not need to be sent, the base station needs to send a physical downlink control signaling to the terminal, so as to inform the terminal to receive the physical downlink data at the frequency domain resource position.
Those skilled in the art should appreciate that other information may not be carried in the frequency domain resource locations to which the portion of the common paging information packet that is not required to be transmitted should be mapped.
Step 840, the base station converts the frequency domain signal containing the part of the common paging information packet and other information into a time domain signal and sends the time domain signal to the terminal side at the paging time.
Step S850, the terminal receives the time domain signal sent by the base station at the paging time, and converts the time domain signal into a frequency domain signal.
And step S860, the terminal demodulates and decodes each public paging information packet at the frequency domain resource position mapped by each public paging information packet, and performs cyclic redundancy check on each public paging information packet.
And if the terminal receives the physical downlink control signaling sent by the base station, receiving the physical downlink data according to the frequency domain resource position indicated by the physical downlink control signaling.
In step S870, the common paging information packet passing the cyclic redundancy check is determined as a successfully detected common paging information packet.
For example: the terminal sends N-x frequency domain resource positions of the public paging information packets at the base station, and the terminal considers that the N-x public paging information packets are successfully detected through cyclic redundancy check.
For another example, the terminal cannot pass the paging redundancy check at the N-x frequency domain resource locations where the base station sent the common paging information packet, and the terminal considers that the base station sent the x common paging information packets but did not successfully detect them, or the terminal considers that the base station did not send the x common paging information packets.
For another example, the terminal cannot pass the paging redundancy check at x frequency-domain resource locations where the base station does not transmit the common paging information packet, and the terminal considers that the base station transmits the x common paging information packets but does not successfully detect the x common paging information packets, or the terminal considers that the base station does not transmit the x common paging information packets.
Step S880, in the successfully detected common paging information packet, obtaining the common paging information of the type according to the type corresponding to each first domain.
Example six
In the present embodiment, the paging information includes dedicated paging information. The base station presets a fixed number of a plurality of special paging information packets, or presets a designated number of a plurality of special paging information packets through higher layer signaling and/or physical layer information.
Fig. 9 is a flowchart of steps for a base station to page a terminal according to a sixth embodiment of the present invention.
Step S910, the base station allocates the special paging information in the paging information into a special paging information packet, and makes the terminal corresponding to the special paging information correspond to a second domain in the special paging information packet.
The number of dedicated paging information packets is fixed, and specifically, which dedicated paging information packet the dedicated paging information corresponding to the terminal is divided into will be described later.
A plurality of special paging information packets are predefined, each special paging information packet comprises one or more second domains, and each second domain corresponds to a terminal. The number of bits per second field is fixed.
After the dedicated paging information is classified into dedicated paging information groups corresponding to the terminals, information of the terminals paged by the dedicated paging information is associated with a second domain. For example: each second field has an index number that is modified using the unique code of the terminal, e.g., the first four digits of the index number are replaced with the second four digits of the unique code.
In this embodiment, all dedicated paging information packets are classified into dedicated paging information, and corresponding terminals exist in all second domains in each dedicated paging information.
Of course, if there is a second field that does not correspond to a terminal in the dedicated paging information packet, the second field is made to correspond to padding bits. The bit-padded second field does not correspond to any terminal.
Step S920, the base station modulates and codes each dedicated paging information packet, and maps a plurality of dedicated paging information packets to different frequency domain resource locations.
The multiple dedicated paging information packets may use the same or different modulation and coding schemes.
After the plurality of special paging information groups are modulated and coded, the plurality of special paging information groups are respectively mapped to different frequency domain resource positions according to a preset resource mapping rule. Furthermore, each dedicated paging information packet corresponds to a fixed frequency domain resource number and a fixed starting frequency domain position, and the dedicated paging information packet is mapped according to the corresponding frequency domain resource number and the starting frequency domain position.
For example: presetting M special paging information groups, dividing the M special paging information groups into public paging information, modulating and coding the M special paging information groups and mapping the M special paging information groups to corresponding frequency domain resource positions, wherein M is more than or equal to 1. As shown in fig. 10, M is 4, and all of the 4 dedicated paging information packets are mapped to corresponding frequency domain resource locations.
Step S930, the base station converts the frequency domain signal containing the plurality of dedicated paging packets into a time domain signal and transmits the time domain signal to the terminal side at the paging time.
In step S940, the terminal receives a time domain signal sent by the base station at the paging time, and converts the time domain signal into a frequency domain signal.
Step S950, the terminal demodulates and decodes the dedicated paging information packet at the frequency domain resource location mapped by the corresponding dedicated paging information packet, and performs cyclic redundancy check on the dedicated paging information packet.
The terminal and the base station adopt the same resource mapping rule, and can determine the frequency domain resource position mapped by the special paging information packet according to the fixed frequency domain resource number and the fixed frequency domain position corresponding to the special paging information packet corresponding to the terminal.
The demodulation decoding adopted by the terminal corresponds to the modulation coding mode adopted by the base station.
In step S960, the dedicated paging information packet passing the cyclic redundancy check is determined as the successfully detected dedicated paging information packet.
For example, if the base station sends the dedicated paging information packet corresponding to the terminal, the terminal considers that the dedicated paging information packet corresponding to the terminal is successfully detected by the terminal in the frequency domain resource location corresponding to the dedicated paging information packet, if the cyclic redundancy check passes, the terminal considers that the base station does not send the dedicated paging information packet corresponding to the terminal, or the terminal considers that the base station sends the dedicated paging information packet corresponding to the terminal but is not successfully detected.
Step S970, in the successfully detected dedicated paging information packet, according to the second domain corresponding to the terminal, acquiring the dedicated paging information corresponding to the terminal.
For example: and searching the index number of each second domain according to the unique code of the terminal, and if the unique code of the terminal is contained in the index number of one second domain, indicating that the special paging information corresponding to the second domain is the special paging information corresponding to the terminal.
In relation to step S910 specifically,

EXAMPLE seven
In the present embodiment, the paging information includes dedicated paging information. The base station presets a fixed number of the special paging information packets, or presets a designated number of the special paging information packets through higher layer signaling and/or physical layer information.
Fig. 11 is a flowchart of steps for paging a terminal by a base station according to a seventh embodiment of the present invention.
Step S1110, the base station allocates dedicated paging information in the paging information into a dedicated paging information packet, and associates a terminal corresponding to the dedicated paging information with a second domain in the dedicated paging information packet.
In this embodiment, among a plurality of dedicated paging information packets into which dedicated paging information is classified, only some dedicated paging information packets need to be transmitted to the terminal side.
The multiple domains in the dedicated paging information packet respectively carry dedicated paging information of multiple terminals, for example, one dedicated paging information packet in the multiple dedicated paging information packets includes 8 second domains, which can carry dedicated paging information of 8 terminals, if only dedicated paging information of 1 terminal arrives at paging time t1, the dedicated paging information packet only carries dedicated paging information of the 1 terminal, and the other 7 second domains are bit-filled, thereby resulting in resource waste. In order to avoid the above resource waste, when the base station only reaches the dedicated paging information of 1 terminal at time t1, the base station may transmit other dedicated paging information packets first without transmitting the dedicated paging information packet in which the dedicated paging information of the terminal is located. When the dedicated paging information of more terminals (for example, 8 terminals) arrives by the paging time t2, the 8 dedicated paging information are put into the unsent dedicated paging information packet.
Step S1120, the base station modulates and codes a part of dedicated paging information packets to be transmitted, and maps the part of dedicated paging information packets to different frequency domain resource locations.
For example: and the M special paging information groups are all divided into special paging information, wherein the z special paging information groups are not sent to the terminal side, the M-z special paging information groups need to be sent to the terminal side, z is more than or equal to 1 and less than or equal to M, and only the M-z special paging information groups which need to be sent to the terminal side are modulated and coded and mapped to corresponding frequency domain resource positions. As shown in fig. 12, M is 4, z is 2, 2 dedicated paging packets that need to be transmitted to the terminal side are mapped to corresponding frequency domain resource positions, and 2 dedicated paging packets that need not to be transmitted to the terminal side are neither modulation-coded nor mapped to corresponding frequency domain resource positions.
Step S1130, the base station converts the frequency domain signal containing the part of the dedicated paging information packet into a time domain signal and transmits the time domain signal to the terminal side at the paging time.
In step S1140, the terminal receives a time domain signal transmitted by the base station at a paging time, and converts the time domain signal into a frequency domain signal.
Step S1150, the terminal demodulates and decodes each dedicated paging information packet at the frequency domain resource location mapped by each dedicated paging information packet, and performs cyclic redundancy check on each dedicated paging information packet.
Step S1160, determining the dedicated paging information packet passing the cyclic redundancy check as the successfully detected dedicated paging information packet.
For example, the base station sends a dedicated paging information packet corresponding to the terminal, and the terminal considers that the dedicated paging information packet corresponding to the terminal is detected through cyclic redundancy check at a frequency domain resource location corresponding to the dedicated paging information packet; if the cyclic redundancy check fails, the terminal considers that the base station does not send the dedicated paging information packet corresponding to the terminal, or the terminal considers that the base station sends the terminal-specific paging information packet but is not correctly received.
For another example, the base station does not transmit the dedicated paging information packet corresponding to the terminal, and the base station does not transmit other information than the paging information at the frequency domain resource location to which the dedicated information packet corresponding to the terminal should be mapped, the terminal cannot pass the cyclic redundancy check at the frequency domain resource location, and the terminal considers that the base station does not transmit the dedicated paging information packet corresponding to the terminal, or the terminal considers that the base station transmits the dedicated paging information packet corresponding to the terminal, but the dedicated paging information packet corresponding to the terminal is not successfully detected.
Step S1170, in the successfully detected special paging information packet, according to the second domain corresponding to the terminal, obtaining the special paging information corresponding to the terminal.
Example eight
In the present embodiment, the paging information includes dedicated paging information. The base station presets a fixed number of the special paging information packets, or presets a designated number of the special paging information packets through higher layer signaling and/or physical layer information.
Fig. 13 is a flowchart of steps for paging a terminal by a base station according to an eighth embodiment of the present invention.
Step S1310, the base station allocates dedicated paging information in the paging information into a dedicated paging information packet, and associates a terminal corresponding to the dedicated paging information with a second domain in the dedicated paging information packet.
In the present embodiment, only a part of the dedicated paging information packets among the plurality of dedicated paging information packets into which the dedicated paging information is classified need to be transmitted to the terminal side.
Of course, if there is a second field that does not correspond to a terminal in the dedicated paging information packet, the second field is made to correspond to padding bits. As shown in fig. 14, a diagram of bit stuffing is shown, where one dedicated paging information packet includes four second domains, the first three second domains have respective corresponding terminals, and the fourth second domain has no corresponding terminal, and then bit stuffing is performed on the fourth second domain. Wherein Ue-Identity represents the unique code of the terminal, and en-Domain is the index number of the second Domain.
Step S1320, the base station modulates and codes a part of dedicated paging information packets to be transmitted, and maps the part of dedicated paging information packets to different frequency domain resource locations.
Step S1330, the base station uses all or a part of the frequency domain resource locations to carry other information in the frequency domain resource locations to which the part of the dedicated paging information packets that need not be transmitted should be mapped.
According to the predefined frequency domain resource mapping rule, the frequency domain resource position corresponding to the special paging information packet which does not need to be sent can be determined.
The other information is, for example, physical downlink data.
If the base station carries the physical downlink data at the frequency domain resource position mapped by the part of the special paging information packets which are not required to be sent, the base station needs to send a physical downlink control signaling to the terminal, so as to inform the terminal to receive the physical downlink data at the frequency domain resource position.
Those skilled in the art will appreciate that other information may not be carried in the frequency domain resource locations to which the portion of the dedicated paging information packet that is not to be transmitted should be mapped.
Step S1340, the base station converts the frequency domain signal containing the part of the dedicated paging information packet and other information into a time domain signal and sends the time domain signal to the terminal side at the paging time.
Step S1350, the terminal receives the time domain signal sent by the base station at the paging time, and converts the time domain signal into a frequency domain signal.
After receiving the physical downlink control signaling sent by the base station, the terminal may receive physical downlink data according to the frequency domain resource location indicated by the physical downlink control signaling.
Step S1360, the terminal demodulates and decodes each dedicated paging information packet at the frequency domain resource location mapped by each dedicated paging information packet, and performs cyclic redundancy check on each dedicated paging information packet.
Step S1370, determines the dedicated paging information packet passing the cyclic redundancy check as a successfully detected dedicated paging information packet.
For example, if the base station sends the dedicated paging information packet corresponding to the terminal, the terminal considers that the dedicated paging information packet corresponding to the terminal is successfully detected by the terminal in the frequency domain resource location corresponding to the dedicated paging information packet, and if the cyclic redundancy check fails, the terminal considers that the base station does not send the dedicated paging information packet corresponding to the terminal, or the terminal considers that the base station sends the dedicated paging information packet corresponding to the terminal but is not successfully detected.
For another example, the base station does not transmit the dedicated paging information packet corresponding to the terminal, and the base station transmits other information besides the paging information at the frequency domain resource location to which the dedicated information packet corresponding to the terminal should be mapped, the terminal cannot pass the cyclic redundancy check at the frequency domain resource location, and the terminal considers that the base station does not transmit the dedicated paging information packet corresponding to the terminal, or the terminal considers that the base station transmits the dedicated paging information packet corresponding to the terminal, but the dedicated paging information packet is not successfully detected.
Step S1380, in the successfully detected special paging information group, according to the second domain corresponding to the terminal, obtaining the special paging information corresponding to the terminal.
