Detailed Description
The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
In Release 15 phase, a wus wake-up signal is introduced, for terminals with the same paging occasion, if there are terminals to be paged, the base station will send wus before the paging occasion, these terminals will all detect wus, and after detecting wus, the terminal will further monitor for paging messages. There are three types of gap types for WUS configured by terminals: DRX_gap, short_eDRX_gap and long_eDRX_gap. The gap is the interval between the start position of the start monitor wus and the PO opportunity. Therefore, when the base station receives the paging message issued by the core network, if the terminal supports WUS, the base station will group according to all the gap types before the PO, and if none of the terminals of the same gap type page, the base station will not send WUS at the WUS position corresponding to the gap type; otherwise, a page will be sent.
The terminal determines wus the start position of the detection by reading the configuration of wus in the SIB message according to the relevant parameters of the configuration wus in the received SIB message, such as the gap value (time offset) between wus and the current PO and the duration of wus.
Since one wus signal corresponds to a plurality of UEs in the R15 stage, and when only one of the UEs needs to be paged, the base station will send wus signals, and for other UEs not needing to be paged, the UEs will be awakened to cause false awakening, and the false awakened UEs will further monitor paging messages to determine whether there is a paging message related to the paging message, thus bringing a certain power consumption overhead; for this purpose, wus supporting packets are introduced in the R16 phase, each group corresponding to one wus signal, which reduces the number of UEs corresponding to one wus signal; however, since the number of R16 UEs is much larger than the number of R15 UEs, the number of UEs corresponding to each WUS after the grouping still appears is still much larger, so that it can be considered that a part of UEs of R16 supporting WUS grouping are assigned to the listening R15 WUS; this can achieve an equalization of the false wake up rates of R15UE and R16 UE.
The embodiment of the invention provides a method for monitoring a wake-up signal, which can be operated on a base station or similar communication equipment. Fig. 1 is a flowchart of a method of listening for a wake-up signal according to an embodiment of the present invention, as shown in fig. 1, the flowchart including the steps of:
step S102, a base station side indicates a part of terminals supporting a first type wake-up signal to monitor a second type wake-up signal;
step S104, the base station side determines the grouping of the wake-up signals according to the indication and sends the corresponding wake-up signals.
In this embodiment, the first type of wake-up signal is a wake-up signal supporting wus packets, for example, may be a 3gpp r16 wake-up signal, and the second type of wake-up signal is a general wake-up signal, for example, may be a 3gpp r15 wake-up signal.
In step S102 of the present embodiment, the base station side may instruct a part of the terminals supporting the R16wus packet to listen to R15wus by:
listening R15wus by indicating one or several wus packets to reach balanced listening wus;
the UE monitoring R15wus is determined by broadcasting the UE supporting R16 packet wus, monitoring the weight value occupied by R15wus and monitoring the weight value occupied by R16 packet wus, so as to achieve balanced monitoring wus;
by broadcasting the UEs supporting R16 packet wus, listening to the proportion of R15wus, it is determined that the UEs listening to R15wus reach balanced listening wus.
In the above-described embodiment of the present invention, the WUS packet is supported by assigning part of R16 UEs to listening R15 WUS; this can achieve an equalization of the false wake up rates of R15UE and R16 UE.
The several above-mentioned indication modes will be described in detail by means of specific examples.
Example 1
In this embodiment, the base station listens to R15wus by indicating one or several wus packets to achieve balanced listening wus. As shown in fig. 2, the method comprises the following steps:
in step S202, the base station indicates that one or several wus packets monitor R15wus in the SIB message, so as to achieve the purpose of assigning a support R16 packet wus to monitor R15 wus.
In step S204, the terminal determines the group identification number of the wus packet to which it belongs according to the wus packet formula, and then determines wus whether to finally monitor R15wus or R16 packet according to the group of assigned monitor R15wus for balanced monitor R15wus and R16wus in SIB message.
In the present embodiment, the following wus grouping formula can be adopted:
sub-group ID＝floor(UE_ID/A)mod B
for eMTC: a=n×ns×nn; for NB-IoT: a=n×ns×w;
wherein UE-id= (imsi+offset) mod 16384, with offset fixed to 0, or with offset being the index of (paging occasion) Po, or with offset being the subframe index+ (index of radio subframe) frame index x 1024, or with offset being the paging carrier index;
wus total number of packets;
N:min(T,nB)；
Ns:max(1,nB/T)；
nn is the number of bands used for paging in eMTC;
w, in NB-IoT, the sum of the weight values of all paging carriers.
In step S206, the base station determines wus transmission according to the same method, specifically calculates wus packet group of the UE, determines that the UE finally listens wus according to the group identification number indicated to be monitored R15wus in the SIB, and then determines wus transmission.
In another embodiment, the base station side calculates the group identification number of the wake-up signal packet to which the terminal belongs according to the following formula:
sub-group ID＝floor(floor(UE_ID/A1)/A2)mod B
wherein, ue_id is (imsi+offset) mod f, where offset is an integer, f is a positive integer, A1 is a variable determined by N, ns, A2 is a positive integer, and B is the total number of packets of the first type wake-up signal packet.
Wherein a1=n×ns, and A2 is Nn or W; f is 16384, the offset is 0, or the offset is the index of paging occasion, or the offset is the index of radio subframe+the index of radio frame 1024, or the offset is the paging carrier index; n=min (T, nB); ns=max (1, nb/T); nn is the number of paging narrowband; w is the sum of the weight values of all paging carriers.

In this embodiment, the base station determines the UE monitoring R15wus by broadcasting the UE supporting R16 packet wus, monitoring the weight value occupied by R15wus and monitoring the weight value occupied by R16 packet wus, so as to achieve the purpose of balanced monitoring wus. As shown in fig. 3, the method comprises the following steps:
in step S302, the base station broadcasts the weight value occupied by the listening R15wus and the weight value occupied by the listening R16 packet wus (e.g. the weight M1 of the number of UEs listening to R15wus, the weight M2 of the number of UEs listening to R16 wus) in the SIB message to achieve the purpose of assigning the number of UEs listening to R15wus in support of R16 packet wus.

floor(UE-ID/(A*B))mod M<M1
for eMTC, a=n×ns×nn; for NB-IoT a=n×ns×w;
wherein UE-id= (imsi+offset) mod 16384, with offset fixed to 0, or with offset being the index of (paging occasion) Po, or with offset being the subframe index+ (index of radio subframe) frame index x 1024, or with offset being the paging carrier index;
total number of packets of wus packets
N:min(T,nB)；
Ns:max(1,nB/T)；
Nn is the number of bands used for paging in eMTC;
w, in NB-IoT, the sum of the weight values of all paging carriers;
m: the UE supporting WUS packets for R16 listens to the sum of the weights of R15WUS and R16WUS.
