Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
In the application scenario of the embodiment of the present invention, as shown in fig. 1, due to the shielding of the building 11, a coverage hole appears in the beam direction 3 (the corresponding BWP is the original BWP) by the base station 12, and as shown in fig. 2, the existence of the coverage hole results in poor quality of the received signal of the terminal, so that the base station 12 repeatedly broadcasts the SSB in the beam direction 3 on the new BWP, and the signal quality of the coverage hole is improved by using the combined diversity gain. For the terminal, if the detected BWP signal level is higher than the set threshold, the terminal autonomously initiates random access on the BWP. Therefore, in the above scenario, with the movement of the terminal, it is assumed that the coverage of the beam direction 3 on the original BWP where the terminal is located is already good enough, and if the terminal residing on the new BWP detects that the signal level of the new BWP is higher than the set threshold, the terminal performs the random access procedure on the new BWP, and once a large number of terminals do the same, the access resource on the new BWP is exhausted, so that the access resource on the new BWP is wasted.
In order to avoid the above problems, in the related art, a network device broadcasts threshold information on a new BWP for a terminal to determine whether to switch from the new BWP to an original BWP for a random access procedure, and switches to the original BWP for the random access procedure when the signal quality measured by the terminal on the new BWP is higher than a corresponding threshold. In this process, it is important how to set the threshold, the threshold is set lower, so that the coverage hole range on the original BWP is defined smaller, and with a high probability, the terminal jumps to the original BWP to perform the random access process, so that the access resource on the original BWP is exhausted, and the access resource on the new BWP is not fully utilized; alternatively, the threshold is set higher, resulting in a larger definition of coverage holes on the original BWP, and with a higher probability, the terminal may perform a random access procedure on the new BWP, resulting in the access resources on the new BWP being exhausted when the access resources on the original BWP are more abundant.
Based on this, in various embodiments of the present invention, the network device determines the relevant threshold information more reasonably based on the relevant information that the terminal performs the random access procedure on the first BWP to the second BWP, and is used for determining whether the terminal performs the random access procedure on the first BWP to the second BWP.
The embodiment of the invention provides an information transmission method, which is applied to network equipment, as shown in fig. 3, and comprises the following steps:
step 301: and sending a first request to the terminal.
Here, the first request is for requesting acquisition of information related to the terminal's conversion from the first BWP to the second BWP for a random access procedure.
In practical application, the network device refers to a base station, such as a next generation node B (gNB) in a 5G system, and the like.
The network device repeatedly broadcasts second information on the first BWP, wherein the second information is SSB of the first direction. In practical application, the first direction may be a coverage hole direction of the network device, for example, the beam direction 3 shown in fig. 1 is a coverage hole direction of the base station. Specifically, the first direction may be a coverage hole direction on the second BWP.
Wherein, the coverage hole is considered to be in the coverage hole direction of the base station signal when the signal quality detected by the terminal is smaller than the corresponding threshold relative to the terminal. The signal quality in the first direction can be improved by the network device repeatedly broadcasting SSBs in the first direction on the first BWP.
In practice, the transition may also be understood as a transfer, that is, the terminal is transferred from the first BWP to the second BWP for performing the random access procedure, in other words, the terminal is transferred from the first BWP to the second BWP for performing the random access procedure.
In actual application, the network device may send a first request, such as an RRC connection reconfiguration message, to the terminal through RRC signaling.
Based on this, in an embodiment, the sending the first request to the terminal includes:
the first request is sent to the terminal through RRC signaling.
Step 302: and receiving the related information reported by the terminal.
Specifically, after the terminal is connected to the network device and enters a connection state, the network device is reported with relevant information that the terminal is converted from the first BWP to the second BWP to perform the random access procedure.
Here, the related information includes at least one of the following information:
the number of times of the terminal for switching from the first BWP to the second BWP to try random access can be obtained through statistics of the sending times of the lead code;
the location of the terminal before the transition occurs and/or the time at which the transition occurs;
the terminal measures the cell signal quality and/or the measured beam signal quality before the switching occurs.
Wherein, in an embodiment, the signal quality may comprise at least one of:
RSRP；
RSRQ；
SINR。
in particular, the cell signal quality may comprise at least one of:
a cell RSRP;
cell RSRQ;
Cell SINR.
In particular, the beam signal quality may comprise at least one of:
beam RSRP;
beam RSRQ;
beam SINR.
Step 303: and determining first information according to the related information.
Here, the first information is used for the terminal to determine whether to switch from the first BWP to the second BWP for performing a random access procedure.
In practical application, the network device determines the first information according to the related information reported by at least one terminal.
The first information may be a corresponding threshold.
Here, the network device determines the first information according to the related information reported by the at least one terminal, that is, determines a threshold for the terminal to determine whether to switch from the first BWP to the second BWP for performing the random access procedure. The network device can correspondingly define the size of the coverage hole where the terminal is located by setting a threshold, specifically, when a coverage hole with a smaller range is defined by setting a lower threshold, a coverage hole with a larger range is defined by setting a higher threshold. Referring to the example of fig. 4, a threshold 1 and a threshold 2 set by the network device based on the related information correspond to the coverage hole range 1 and the coverage hole range 2 in fig. 3, respectively, where the threshold 1 is lower than the threshold 2; accordingly, the coverage hole range 1 is smaller than the coverage hole range 2, and when the network device configuration threshold 2 is the first information, the terminal located outside the coverage hole range 1 and on the edge of the coverage hole range 2 may also reside on the first BWP to perform the random access procedure. Therefore, the network device can more reasonably adjust the size of the coverage hole range based on the related information reported by the terminal, so as to reasonably adjust the number of terminals performing the random access process on the first BWP and the second BWP, and avoid excessive consumption of access resources on any BWP.
In practical application, the network device can determine the signal quality distribution in each time period within the coverage of the network device according to the related information reported by the terminal. Referring to fig. 5, according to the related information reported by the terminal in the coverage area in a set time period, it can be determined that the signal quality at the corresponding position in the coverage area of the base station in the figure is-60 dBm, -63dBm, -68dBm, -80dBm and-82 dBm respectively in the set time period. In addition, in the coordinates below fig. 5, the abscissa indicates the signal quality, and the ordinate indicates the number of terminals corresponding to the signal quality, and after knowing the signal quality of the corresponding area in the coverage area, the base station can define a certain number of terminals in the coverage hole range by adjusting the threshold, so that the terminals reside on the first BWP to perform the random access procedure; or defining a certain number of terminals out of the coverage hole range, so that the terminals are converted to the second BWP to perform a random access process, thereby regulating and controlling the number of the terminals and realizing the balanced consumption of access resources on the first BWP and the second BWP.
In practical applications, the network device may determine a lower threshold at the early stage of the deployment of the first BWP, that is, define the coverage hole to be smaller, so that a larger number of terminals switch from the first BWP to the second BWP to perform the random access procedure, thereby increasing the number of terminals reporting the relevant information, and acquiring a larger number of relevant information, so as to determine more reasonable first information based on more relevant information.
In practical application, the network device sends the first information to the terminal after determining the first information, so that the terminal judges whether to convert BWP according to the first information to perform a random access process.
Based on this, in an embodiment, as shown in fig. 6, the method may further include:
step 304: the first information is sent on the first BWP.
In order for terminals within the coverage area to receive the first information, the first information may be transmitted by broadcasting.
Based on this, in an embodiment, the sending the first information on the first BWP comprises:
the first information is broadcast over the first BWP by a broadcast message.
Here, when the network device broadcasts the first information through the broadcast message on the first BWP, the terminal receives the first information from the broadcast message to determine the corresponding threshold. When the signal quality detected by the terminal is greater than the corresponding threshold, the terminal determines not to perform the random access procedure on the first BWP but to perform the random access procedure on the second BWP through frequency hopping.
Correspondingly, the embodiment of the invention also provides an information transmission method which is applied to the terminal. As shown in fig. 7, the information transmission method provided by the embodiment of the present invention includes:
Step 701: and receiving a first request sent by the network equipment, wherein the first request is used for requesting to acquire the related information of the terminal which is converted from the first BWP to the second BWP for performing the random access process.
Here, the network device transmits a first request to the terminal for requesting acquisition of information related to the terminal's conversion from the first BWP to the second BWP for the random access procedure.
In an embodiment, the receiving the first request sent by the network device includes:
and receiving a first request sent by the network equipment through RRC signaling.
The network device repeatedly broadcasts second information on the first BWP, wherein the second information is SSB of the first direction. In practical application, the first direction may be a coverage hole direction of the network device, for example, the beam direction 3 shown in fig. 1 is a coverage hole direction of the base station. Specifically, the first direction may be a coverage hole direction on the second BWP.
Wherein, the coverage hole is considered to be in the coverage hole direction of the base station signal when the signal quality detected by the terminal is smaller than the corresponding threshold relative to the terminal. The signal quality in the first direction can be improved by the network device repeatedly broadcasting SSBs in the first direction on the first BWP.
Step 702: reporting the related information to the network equipment; the related information is used for the network equipment to determine first information; the first information is used for the terminal to judge whether to switch from the first BWP to the second BWP to perform a random access procedure.
Specifically, after the terminal is connected to the network device and enters a connection state, the network device is reported with relevant information that the terminal is converted from the first BWP to the second BWP to perform the random access procedure.
Here, the related information includes at least one of the following information:
the number of times of the terminal for switching from the first BWP to the second BWP to try random access can be obtained through statistics of the sending times of the lead code;
the location of the terminal before the transition occurs and/or the time at which the transition occurs;
the terminal measures the cell signal quality and/or the measured beam signal quality before the switching occurs.
In an embodiment, as shown in fig. 8, the method further comprises:
step 703: and receiving the first information sent by the network equipment on the first BWP.
Further, in an embodiment, the receiving the first information on the first BWP includes:
First information broadcast by the network device over the first BWP through a broadcast message is received.
Here, the network device transmits the first information on the first BWP, and when the network device broadcasts the first information on the first BWP through a broadcast message, the terminal in an idle state receives the first information from the broadcast message to determine the corresponding threshold. When the signal quality detected by the terminal is greater than the corresponding threshold, the terminal determines not to perform the random access procedure on the first BWP but to perform the random access procedure on the second BWP through frequency hopping.
