The present application claims priority to Chinese Patent Application No. 201710201251.X filed on March 30, 2017, the entire content of which is hereby incorporated by reference.

Technical field

The embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a method, a receiving method, a base station, and a terminal for sending a paging message.

Background technique

The 5G high frequency band needs to use a large-scale antenna to counter the path loss problem. The analog digital hybrid beamforming architecture is the most likely architecture for 5G high-frequency large-scale antennas (combined from cost, complexity, performance, etc.). However, since analog beamforming can only change the beam direction in the time domain and is a full bandwidth behavior, analog digital hybrid beamforming will have a greater impact on 5G system design. One of the effects is paging. )The way.

In the 5G high-band system, the beam of the base station is relatively narrow, and the analog beam can only be adjusted in time. If the paging message is still sent in a similar manner to that in LTE, since the base station does not know the location of the paged user, the paging message can only be transmitted on all possible beams by means of beam scanning. This means that even if it is only for paging a certain UE, the base station needs to use different beams to send the same paging message in multiple subframes in sequence, which makes one paging (one PO) need to occupy multiple subframes, resulting in The time that the UE needs to monitor becomes longer and the power consumption increases. Moreover, since different UEs use different POs, the base station needs to page different users at different times. Each paging user needs to use beam scanning to consume multiple subframes to send paging messages. In addition, when some subframes need to send paging messages by means of beam scanning, the analog beams that can be used in these subframes are limited, which also reduces the flexibility of base station scheduling.

detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

First embodiment

In the LTE system, the role of the paging message includes transmitting a call request to the user equipment UE in the RRC_IDLE state, and notifying the UE system information in the RRC_IDLE and RRC_CONNECTED states. Change and so on.

PCH (Paging Channel) is used to transmit paging messages from the PCCH (Paging Control Channel) logical channel. The PCH transport channel is directly mapped to the PDSCH (Physical Downlink Shared Channel) physical channel, and the DL-SCH (downlink sharing) Channel) data participates in downlink scheduling.

In order to receive a paging message from the eNodeB (Node B), the UE in the RRC_IDLE state will listen to the PDCCH scrambled using the P-RNTI (Paging Identity). Paging supports discontinuous reception (DRX), so that the UE in the RRC_IDLE state "wakes up" to receive the paging message only for a predefined period of time, and can maintain the "sleep" state at other times, thus being able to reduce Power consumption increases the battery life of the UE.

The frequency domain resource occupied by the paging message is specified by the PDCCH (Physical Downlink Control Channel). In the time domain, the UE will only attempt to receive paging messages in a specific subframe (referred to as PO) of a specific frame (referred to as PF) in its paging cycle.

When DRX (Discontinuous Reception) is used, the UE only needs to detect 1 PO per DRX cycle (discontinuous reception period). That is, corresponding to each UE, only 1 subframe can be used to transmit a paging message in each paging cycle.

A PF (Paging Frame) is a radio frame that may contain one or more POs.

PF is a system frame that satisfies the following formula: SFN mod T = (T div N) * (UE_ID mod N). Where (T div N) is equivalent to dividing a DRX cycle into N shares, each system frame included, (UE_ID mod N) is equivalent to taking the "UE_ID mod N" in the N equal part (value range It is 0 to N-1), and PF is the first system frame among them, where UE_ID is IMSI mod 1024. One PF may include one or more POs according to the configuration, and which UE is specifically detected on which PO depends on the UE_ID.

If the UE detects a PDCCH scrambled using the P-RNTI on the PO, the UE reads the PDSCH, which contains the flag ue-Identity of the paged UE.

If the UE finds that its UE flag is consistent with a certain ue-Identity, it sends the ue-Identity and related information to the upper layer to continue processing.

If the UE does not find a ue-Identity that is consistent with its UE flag, the UE discards the received paging message and goes to sleep.

In the LTE system, from the perspective of a certain UE, it is only necessary to monitor its own PO (the specific PO location is related to the IMSI). In this way, the power consumption can be reduced and the battery life of the UE can be improved. For the base station, paging messages may be sent on the POs of all UEs.

As shown in FIG. 1 , an embodiment of the present disclosure provides a method for sending a paging message, including:

Step 11: Send at least one first physical downlink control channel PDCCH message, where the first PDCCH message carries first indication information indicating a resource used when sending a paging message; optionally, a child that sends a paging message Transmitting, by the frame, at least one first physical downlink control channel PDCCH message, where the first PDCCH message carries first indication information indicating a resource used when sending the paging message;

Step 12: Send, by using the resource, at least one paging message to at least one terminal configured to have the same identifier; optionally, in the subframe, according to the first indication information, configured to have At least one terminal of the same identity transmits at least one paging message.

The method for sending a paging message in this embodiment is applicable to a 5G system in which a paging moment in a paging cycle of a certain UE (such as a paging frame) and a paging Occasion (paging opportunity) is determined in the system. The UE_ID (terminal identifier) used at the time may be configured by the network side (for example, by means of system messages, etc.), and the network side may be configured such that two or more users use the same UE_ID, so that the terminals of the same UE_ID can be Listening to paging messages at the same time (such as paging frames or paging moments), so that from the perspective of the base station, less time resources can be allocated for potential paging message transmission, reducing scheduling flexibility for the base station. limits.

In this embodiment, in step 11, the method may include: sending, in a subframe in which the paging message is sent, at least one first PDCCH message scrambled by the paging identifier P-RNTI.

For example, when a time scheduling unit (such as a subframe, or a time slot, or a mini-slot) is used for paging, the following method may be adopted, assuming that the subframe at this moment is divided into a PDCCH region and a PDSCH region. :

In the PDCCH region, the base station transmits N1 PDCCHs scrambled by the P-RNTI, each PDCCH corresponding to a beam of the base station (which may correspond to coverage of one or more beams) indicating one or more pagings The message (each paging message sent by a base station beam) occupies resources in the PDSCH region; where N1 is a positive integer.

Further, in the foregoing embodiment, the resources used when sending the paging message include: a beam used to send the paging message and an OFDM (Orthogonal Frequency Division Multiplexing) symbol resource occupied by the paging message; The symbol resource occupied by the message may be a symbol resource occupied by the paging message on the PDSCH (Physical Downlink Shared Channel), and the resource occupied by the paging message on the PDSCH may include: a symbol resource occupied by the paging message on the PDSCH and a bandwidth resource.

Correspondingly, the step 12 in the foregoing embodiment may include: using the beam indicated by the first indication information, on the OFDM resource occupied by the paging message indicated by the first indication information, to be configured to have the same identifier At least one terminal transmits at least one paging message. Specifically, in the subframe in which the paging message is sent, by using the beam indicated by the first indication information, the paging message indicated by the first indication information is configured on the OFDM resource occupied by the PDSCH to be configured as At least one terminal having the same identity transmits at least one paging message.

For example, in the PDSCH area, the base station sends N2 paging messages, and each paging message is sent by a certain beam; where N2 is a positive integer.

Optionally, in the above embodiment of the present disclosure, one paging message is sent through one beam. The paging messages corresponding to different beams occupy the OFDM symbol resources by means of time division multiplexing or frequency division utilization. Specifically, the paging message corresponding to different beams occupies the PDSCH by means of time division multiplexing or frequency division utilization. A paging message occupies at least one OFDM symbol resource of the PDSCH or a paging message occupies part of the bandwidth or the entire bandwidth on the PDSCH. Different paging messages occupy the same bandwidth on the PDSCH or different paging messages occupy different bandwidths on the PDSCH.

That is to say, the allocation of the resources occupied by the paging message does not occupy all the symbols of the PDSCH area, and one paging message can occupy only one or more symbols of the PDSCH area, and multiple paging messages corresponding to different beams pass. The TDM (Time Division Multiplexing) mode occupies the PDSCH area. A paging message can occupy the entire bandwidth or occupy only part of the bandwidth.

In addition, the number of PDCCHs N1 and the number of paging messages N2 may be one-to-one or one-to-many relationship, that is, one PDCCH may indicate information such as resource occupation, used beams, and the like of one or more paging messages.

In this embodiment of the present disclosure, the first PDCCH message may also be transmitted through a beam of the base station, and the beam may also be a beam specified by the first PDCCH message, and the beam may be the same beam used when transmitting the paging message. Beam. For example, PDCCH1 specifies beam 1 for transmitting paging message 1, and PDCCH1 can also be transmitted with beam 1. PDCCH2 specifies to transmit beam 2 of paging message 2, which may also be transmitted using beam 2. Of course, if PDCCH1 specifies the beam 2 used in the paging message 1 and the beam 2 used in the paging message 2, the PDCCH 1 may be transmitted by using the beam 1 or by using the beam 2. Of course, in other embodiments of the present disclosure, there may be other manners for transmitting the PDCCH, and is not limited to the manners listed above.

The implementation process of the method described in the foregoing embodiment is described below with reference to specific application examples:

As shown in FIG. 2, it is assumed that the base station needs to scan on three beams to cover the entire cell, and the base station needs to send paging messages to the two UEs at the moment, and the two UEs may have the same UE ID, of course, the two UEs. It is also possible to have different UE IDs.

In the PDCCH region, the base station transmits three PDCCHs (PDCCH1, PDCCH2, and PDCCH3) scrambled by the P-RNTI, and respectively indicate information such as resources occupied by the three paging messages and beams used. Specifically, PDCCH1 indicates information such as a symbol resource occupied by paging message 1, a used beam, and the like. PDCCH2 indicates information such as a symbol resource occupied by the paging message 2, a used beam, and the like. The PDCCH 3 indicates information such as a symbol resource occupied by the paging message 3, a used beam, and the like.

In the PDSCH area, the base station sends three paging messages, which respectively correspond to different beams. Each paging message occupies 1 symbol and occupies the full bandwidth of the PDSCH.

As shown in FIG. 3, it is assumed that the base station needs to scan on three beams to cover the entire cell, and the base station needs to send paging messages to the two UEs at the moment, and the two UEs may have the same UE ID, of course, the two UEs. It is also possible to have different UE IDs.

In the PDCCH region, the base station transmits two PDCCHs scrambled by the P-RNTI, where one PDCCH indicates information such as resources occupied by two paging messages (Paging Message 1 and Paging Message 2), used beams, and the like. Another PDCCH indicates information such as resources occupied by one paging message, beams used, and the like.

As shown in FIG. 4, it is assumed that the base station needs to scan on three beams to cover the entire cell, and the base station needs to send paging messages to the two UEs at the moment, and the two UEs may have the same UE ID.

In the PDCCH region, the eNB transmits three PDCCHs scrambled by the P-RNTI, and indicates information such as resources occupied by the three paging messages and beams used.

In the PDSCH area, the base station sends three paging messages, which respectively correspond to different beams. Each paging message occupies 1 symbol, but 3 paging messages can occupy different bandwidths of the PDSCH.

Step 52: Send, according to the first indication information, at least one paging message to at least one terminal configured to have the same identifier, and according to the second indication information, to at least one of the configured to have the same identifier. The terminal transmits the user data.

In this embodiment of the present disclosure, the PDSCH area that is not occupied by the paging message may be used to transmit the PDSCH of the normal user data, but the time-frequency resource occupied by the PDSCH needs to be indicated in the corresponding PDCCH, and the PDSCH is compared with the normal subframe. The symbol resource that needs to indicate that the PDSCH is occupied is not all symbol resources of the PDSCH region.

As shown in FIG. 6, the PDSCH area that is not occupied by the paging message can be used to transmit the PDSCH of the normal user data, but the time-frequency resource that the PDSCH occupies in the corresponding PDCCH4 needs to be indicated, and is required for the PDSCH of the normal subframe. The symbol resource indicating that the PDSCH is occupied is not all symbol resources of the PDSCH region.
