The embodiments of the present invention are described below in conjunction with the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the application and are not limiting.

Embodiment 1

This embodiment provides a paging method performed at a first transmission node.

In this embodiment, the first transmission node determines paging configuration information and paging indication information for paging the third transmission node, and sends the same paging configuration information and paging indication information to the at least one second transmission node, So that the second transmitting node sends a paging message to the third transmitting node according to the paging configuration information and the paging indication information. In other words, in this embodiment, the paging configuration information and the paging indication information sent by the first transmission node to the at least one second transmission node are the same.

The paging configuration information includes at least one of the following information: paging cycle, candidate time-frequency location, transport block size, modulation mode, resource allocation, number of repeated transmissions, Cyclic Prefix (CP) type, transmission mode, and scrambling Logo.

The paging indication information includes at least the following information: an identifier of the third transmission node. The third transmission node is a transmission node indicating that the first transmission node is paging by the first transmission node.

The second transmission node is a transmission node that can page the third transmission node. In this embodiment, the number of second transmission nodes is at least one. For example, there are three second transmission nodes. In this way, the at least one second transmission node can form a paging area, and the at least one second transmission node can perform paging according to the received paging configuration information and the paging indication information.

In this embodiment, the first transit node may be a Mobile Management Entity (MME). The second transmission node can be a target base station. The third transmission node may be a terminal device. The identifier of the third transmission node is, for example, an International Mobile Subscriber Identification Number (IMSI) of the third transmission node.

The MME determines, according to the terminal device that needs to be paged, the target base station that can page the terminal device; the number of target base stations is at least one; the paging configuration information that the MME needs to use when paging, and the terminal device information that needs to be paged. The paging indication information (eg, the identifier of the terminal device) is respectively sent to each target base station; each target base station pages the terminal device according to the received paging configuration information and paging indication information.

The MME may also send the same indication information of the number and location of the specified time-frequency positions to each target base station, so that each target base station simultaneously pages the terminal device at the specified time-frequency position indicated by the indication information.

In this embodiment, all target base stations in the same paging area can follow the same transmission format (corresponding transport block size, modulation mode, resource allocation, number of repeated transmissions, cyclic prefix CP type, transmission mode, and scrambling identification). And transmitting the same paging message to the terminal device at the same time-frequency location (determined according to the paging cycle, the candidate time-frequency location, and the identity of the terminal device), thereby maximizing paging with minimum resources by this embodiment Coverage of the message.

Embodiment 2

This embodiment provides a paging method performed at a second transmission node. 1 is a flow chart of a paging method in accordance with a second embodiment of the present invention.

Step S110: Receive paging configuration information and paging indication information sent by the first transmission node.

The paging configuration information includes at least one of the following information: a paging cycle, a candidate time-frequency location, and a transmission Block size, modulation mode, resource allocation, number of repeated transmissions, cyclic prefix CP type, transmission mode, and scrambling identification.

The paging indication information includes at least the following information: an identifier of the third transmission node. The identifier of the third transmission node is one or more.

Step S120: Send the paging configuration information to the third transmission node.

Step S130, sending a paging message to the third transmitting node according to the paging configuration information and the paging indication information.

Determining, according to the paging period, the candidate time-frequency location, and the identifier of the third transmission node, a time-frequency location for paging the third transmission node, that is, determining that the first a time-frequency location of a paging message of the three transmission nodes; wherein a time-frequency location for paging the third transmission node belongs to the candidate time-frequency location; according to the paging for the third transmission node And transmitting, by the time-frequency location, a paging message for paging the third transmitting node to the third transmitting node.

In an embodiment, in a time-frequency location for paging the third transmitting node, determining a specified time-frequency location for transmitting a paging message for paging the third transmitting node; wherein, specifying a time-frequency a location after the paging indication information arrives and belongs to the time-frequency location for paging the third transmission node; sending, at the designated time-frequency location, the third transmission node for paging The paging message of the third transmission node.

The number and location of the specified time-frequency locations are predefined or indicated by the first transit node. Determining, at a time-frequency location for paging the third transmitting node, a specified time-frequency location for transmitting a paging message for paging the third transmitting node, based on the number and location of the designated time-frequency locations. The time-frequency location for paging the third transmission node is multiple, and the number of designated time-frequency locations may also be multiple, and each specified time-frequency location belongs to the third transmission node for paging. The time-frequency position, and in the time domain, each of the specified time-frequency locations is located after the arrival of the paging indication information. By transmitting a paging message for paging the third transmission node at a plurality of designated time-frequency locations, the transmission opportunity of the paging message is increased, thereby facilitating the improvement of the coverage of the paging message.

For example, the predefined designated time-frequency location is one or a plurality of consecutive time-frequency locations for paging the third transmission node after the arrival of the paging indication information.

For another example, the designated time-frequency position indicated by the first transmission node (MME) is one or a plurality of consecutive time-frequency positions for paging the third transmission node, starting from the indicated time domain interval segment.

The paging message may be modulated by a modulation method in the paging configuration information before the paging message is sent to the third transmission node.

When the paging message is sent to the third transmission node, the paging message may be scrambled according to the scrambling identifier in the paging configuration information. The method ensures that each paging transmission message can be used to page a plurality of third transmission nodes, and each third transmission node can obtain the scrambling identifier of the paging message. In an embodiment, the paging message size, the resource allocation, the cyclic prefix type, and the transmission mode in the paging configuration information are used, and the paging message is sent to the third transmitting node at a specified time-frequency location, and the paging message is followed. The number of repeated transmissions in the configuration information is repeated, and the paging message is repeatedly sent to the third transmission node.

If the paging configuration information does not include a paging cycle, a candidate time-frequency location, a transport block size, a modulation scheme, a resource allocation, a number of repeated transmissions, a cyclic prefix CP type, a transmission mode, or a scrambling identifier, a predefined paging may be used. Period, candidate time-frequency location, transport block size, modulation scheme, resource allocation, number of repeated transmissions, cyclic prefix CP type, transmission mode, or scrambling identification.

In this embodiment, an indication of whether a paging message exists in a time-frequency location other than the candidate time-frequency location may be sent to the third transmission node. And if the third transmission node sends an indication that there is a paging message at a time-frequency location other than the candidate time-frequency location, the third transmission may be performed at a time-frequency location other than the candidate time-frequency location. The node sends a paging message.

In this embodiment, the third transmission node may not send an indication of whether there is a paging message at a time-frequency location other than the candidate time-frequency location, but directly outside the candidate time-frequency location. And transmitting a paging message to the third transmission node.

In this embodiment, the time-frequency location (ie, the additional time-frequency location) other than the candidate time-frequency location does not depend on the paging configuration information from the first transmission node that includes the paging cycle and the candidate time-frequency location. Rather, it relies on the additional paging configuration information of the paging node and the candidate time-frequency location indicated by the second transmitting node itself to the third transmitting node, and the second transmitting node follows the controlled transmission mode at the additional time-frequency. The location sends a paging message. This embodiment further enhances the search The coverage of the call message within the current second transit node.

The following describes the information in the paging configuration information:

The paging cycle is a period for paging the time domain location of the third transmission node, and the paging cycle includes an integer power of 2 time domain interval segments. Time domain interval segments include, but are not limited to, radio frames and superframes.

The candidate time-frequency locations include configuration information of candidate time domain locations and/or candidate frequency domain locations. The target base station and the terminal device can only transmit and receive paging messages within the range of candidate time-frequency locations (candidate time domain locations and/or candidate frequency domain locations).

The candidate time domain locations occur periodically, and the number of candidate frequency domain locations is one or more.

The candidate time domain location corresponds to a set of time domain resource units, and the time domain resource unit in the set can serve as a starting location for paging message transmission (also referred to as paging occasion). Time domain resource units include, but are not limited to, subframes and time slots.

The candidate frequency domain location corresponds to a set of bandwidths, and one bandwidth in the set corresponds to one candidate frequency domain location. The bandwidth in the set can be used to transmit paging messages. Wherein each bandwidth includes one or more resource blocks.

For the candidate time domain location, the configuration information of the candidate time domain location includes, but is not limited to, the offset X and the parameter nB of the time domain interval segment where the candidate time domain location is located. The offset X may be a sequence number of the time domain interval segment in which the candidate time domain location is located in the candidate time domain location period (for example, if the period of the candidate time domain location is 32, the offset X ranges from 0 to 31). The value range of nB is (2 ⁿ )*T, where n is an integer greater than or equal to N1 and less than or equal to N2, T is a paging cycle, N1 is a negative integer (eg, N1=-8), and N2 is a positive integer (eg, N2=2). The values of N1 and N2 are fixed values (which may be empirical values or experimentally obtained values).

When n takes 0 or takes a positive integer, it indicates that the candidate time domain location is located in each time domain interval segment, and each time domain interval segment includes 2 ⁿ candidate time domain locations; the 2 ⁿ candidate time domain locations are in each The locations within the time domain interval segments (e.g., subframe or slot number) may be predefined. In other words, the candidate time domain location period is 1 time domain interval segment and the offset X defaults to 0.

When taking the negative integer n, the time domain representing a candidate location in every period of a time domain time-domain 2 ^-n continuous range segment, and the segment comprises a time domain interval when only one candidate position domain. In other words, the candidate time domain location period is 2 - ⁿ time domain interval segments. The location of the one candidate time domain location within the time domain interval segment may be predefined.

For the candidate frequency domain location, the configuration information of the candidate frequency domain location includes, but is not limited to, the number of candidate frequency domain locations N _B (ie, the number of bandwidths) and the location of the candidate frequency domain location (ie, the frequency band corresponding to each bandwidth) Thus, the frequency domain resource range corresponding to each candidate frequency domain location can be determined.

The transport block size refers to the transport block size used when sending a paging message.

Modulation methods include, but are not limited to, Quadrature Phase Shift Keying (QPSK) modulation.

For resource allocation, when a primary transmission of a paging message is limited to a range of time domain resource units and the paging message is allowed to occupy a partial resource block within a candidate frequency domain location, the resource allocation includes: the paging message is in a candidate The number and location of resource blocks occupied in the frequency domain location. When a transmission of a paging message always occupies all resource blocks within a candidate frequency domain location and allows one transmission of the paging message across multiple consecutive time domain resource units, the resource allocation includes: one transmission of the paging message The number of consecutive multiple time domain resource units occupied.

The number of repeated transmissions refers to the number of times the paging message is repeatedly transmitted to the third transmission node at a specified time-frequency location for transmitting a paging message for paging the third transmission node.

Cyclic prefix CP types include: normal CP type and extended CP type. The normal CP type is suitable for small coverage cells, and the extended CP type is suitable for large coverage cells.

Transmission modes include: single antenna port mode and two antenna port mode. The two antenna port mode is equivalent to the Space Frequency Block Code (SFBC) mode.

The scrambling flag is used to scramble the paging message. The scrambling identifier is, for example, a Paging Radio Network Tempory Identity (P-RNTI).

For step S130:

After the paging indication information arrives, determining, according to the paging period and the candidate time-frequency location in the paging configuration information, and the identifier of the third transmission node in the paging indication information, determining the time for paging the third transmission node Frequency position. The time-frequency location includes a time domain location and a frequency domain location. In one implementation In the manner, among all candidate time domain locations, a time domain location for paging the third transmission node is determined; and among all candidate frequency domain locations, a frequency domain location for paging the third transmission node is determined.

As shown in FIG. 2, it is a flow chart showing the steps of determining the time domain location and the frequency domain location of the paging third transmission node according to the second embodiment of the present invention.

Step S210: Determine, according to the paging cycle, the candidate time domain location, and the identifier of the third transit node, a time domain interval segment for paging the time domain location of the third transit node.

The time domain interval segment in which the time domain location for paging the third transmission node is located may be determined according to the following formula (1):

(N _D -X) mod T=(T/N)×(UEID mod N) (1)

In formula (1), mod() is a remainder function; N _D is the number of the time domain interval segment in which the time domain location is located; X is the offset of the time domain interval segment where the candidate time domain location is located; T is the search The call period (the unit is the time domain interval segment); N is the minimum value in T and nB, nB is equal to (2 ⁿ )*T; the UEID is the number corresponding to the identifier of the third transmission node. The number corresponding to the identifier of the third transmission node is, for example, the remainder after the identifier is divided by a preset integer (for example, 1024).

Step S220, determining a time domain location for paging the third transmission node in a time domain interval segment in which the time domain location for paging the third transmission node is located.

The time domain location for paging the third transport node can be determined according to the following formula (2):

I _U =floor(UEID/N)mod N _S (2)

Wherein floor() represents a downward rounding function; I _U represents a logical index of a time domain position for paging the third transport node among all candidate time domain locations included in the time domain interval segment determined by equation (1), N _s is the maximum value of 1 and nB/T, and N _s represents the number of candidate time domain positions included in the time domain section determined by the formula (1).

Step S230, determining a frequency domain location for paging the third transmission node according to the candidate frequency domain location and the identifier of the third transmission node.

Wherein, the frequency domain location for paging the third transmission node may be determined according to the following formula (3):

I _B =floor(UEID/(N×N _S ))mod N _B (3)

In equation (3), I _B denotes a logical index for paging the frequency domain position of the third transmission node in all candidate frequency domain locations, and N _B is the number of candidate frequency domain locations.

And determining, according to the paging period and the candidate time-frequency position in the paging configuration information, and the identifier of the third transmitting node in the paging indication information, determining, in all candidate time-frequency positions, the third transmitting node for paging Time domain location and frequency domain location.

In this embodiment, the transport block size, the modulation mode, the resource allocation, the number of repetitions, the CP type, the transmission mode, and the scrambling identifier used by the second transmitting node when transmitting the paging message are sent to the second transmission by the first transmitting node. The transport block size, modulation scheme, resource allocation, number of repetitions, CP type, transmission mode, and scrambling identity of the node. That is to say, in this embodiment, the paging message is transmitted in a manner that does not depend on the physical downlink control channel (ie, no control), and the transmission mode (physical downlink control channel) that is traditionally dependent on the physical downlink control channel (ie, has control) Compared with the unsupported transmission mode, the embodiment can save more downlink control overhead.

An example is provided below, and Fig. 3 is a schematic diagram of a paging method according to a second embodiment of the present invention.

The number of target base stations is three, which are represented as base station 0, base station 1 and base station 2, respectively. The base station 0, the base station 1 and the base station 2 use the same transport block size, modulation mode, resource allocation, repetition number, CP type, transmission mode and scrambling identifier to send a paging message to the terminal device at the same designated time-frequency location.

The designated time-frequency location is after the arrival of the paging indication information and is one of the time-frequency locations of all the time-frequency locations used to page the terminal device.

One transmission of the paging message occupies all resource blocks within a specified frequency domain location (or bandwidth), and the resource allocation includes: the number of consecutive multiple time domain resource units occupied by one transmission of the paging message. That is to say, in the bandwidth range, paging messages and other data can only share time-frequency resources in a time division multiplexing (TDM) manner.

The resource allocation of FIG. 3 is six time domain resource units (one time domain resource unit corresponds to one square in FIG. 3), that is, one transmission of the paging message occupies six consecutive time domain resource units. If the number of repeated transmissions of the paging message is 2, the paging message finally occupies a total of 12 consecutive time domains. The resource unit, as shown in FIG. 3, has two different grayscale squares corresponding to the first transmission of the paging message and the second transmission of the paging message, respectively.

The modulation mode and the transport block size used by the paging message of FIG. 3 are QPSK modulation and 328 bits, respectively, and the paging message uses a normal CP type and a single antenna port mode, and is agreed or predefined by the P-RNTI. Call the message to scramble.

In this embodiment, the paging message for paging the third transmission node is a paging message dedicated to paging the third transmission node (ie, the paging message is only allowed to page a third transmission node); or, paging The paging message of the third transmission node is used for paging other third transmission nodes in addition to paging the third transmission node (ie, allowing paging messages to simultaneously page one or more third transmission nodes), wherein The time-frequency location of the paging message used to page the third transmitting node is the same as the time-frequency location used to page any of the other third transmitting nodes.

When the paging message is only allowed to page a third transmitting node, the scrambling identifier may not be indicated in the paging configuration information, and the scrambling identifier of the paging message may be directly equivalent to the identifier of the third transmitting node.

If the number of the third transmission nodes that need to be paged at the current time-frequency location exceeds one, the base station is implemented to page only one of the third transmission nodes at the time-frequency location, and abandon or postpone the other third transmission nodes. Paging. The time-frequency position may be selected among the time-frequency positions that have been determined for paging the third transmission node, and the other third transmission nodes that are postponed may be paged.

When a paging message is allowed to simultaneously page one or more third transmitting nodes, the maximum number of third transmitting nodes allowed to be paged is limited by the transport block size in the paging configuration information; if the configured transport block size is insufficient The number of third transmission nodes that need to be paged at the current time-frequency location depends on the base station to implement the abandonment or postponement of paging of the one or more third transmission nodes at the time-frequency location.

The second transmission node sends paging configuration information to the third transmission node. Wherein, all paging configuration information is sent through broadcast signaling or third transmission node-specific signaling, or partial paging configuration information is sent through broadcast signaling and the remaining paging configuration is sent through third signaling node-specific signaling. information.

Step S410: Receive paging configuration information sent by the second transmission node, where the paging configuration information is sent by the first transmission node to the second transmission node.

Step S420, receiving, according to the paging configuration information, a paging message sent by the second transmission node.

The paging configuration information includes at least one of the following information: a paging cycle, a candidate time-frequency location, a transport block size, a modulation mode, a resource allocation, a number of repeated transmissions, a cyclic prefix CP type, a transmission mode, and a scrambling identity.

Determining, according to the paging period and the candidate time-frequency location in the paging configuration information, and the identifier of the third transmitting node, a time-frequency location used by the second transmitting node to page the third transmitting node; And the time-frequency location for paging the third transmission node belongs to the candidate time-frequency location; and the second transmission node is received at the time-frequency location for paging the third transmission node. A paging message sent for paging the third transmission node.

In this embodiment, an indication of whether a paging message exists at a time-frequency location other than the candidate time-frequency location sent by the second transmission node is received. In an embodiment, if an indication that the paging message exists in the time-frequency location other than the candidate time-frequency location sent by the second transmission node is received, receiving at a time-frequency location other than the candidate time-frequency location a paging message sent by the second transmission node.

In this embodiment, if there is no indication that the second transmission node sends a paging message at a time-frequency location other than the candidate time-frequency location, the candidate time-frequency is directly The time-frequency location outside the location receives the paging message sent by the second transmission node.

In this embodiment, a time-frequency position other than the candidate time-frequency position (ie, an additional time-frequency bit) Arranging configuration information that does not depend on the paging cycle and the candidate time-frequency location from the first transmission node, depends on configuration information of the additional paging cycle and the candidate time-frequency location indicated by the second transmission node itself to the third transmission node And the third transmitting node receives the paging message at the additional time-frequency location in a controlled receiving manner. The method further enhances the coverage of the paging message within the current second transmission node.
