Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, in order to follow the principle of a simple design, 5G supports SIB2 and "on-demand transmission" of subsequent broadcast signals, that is, the base station side transmits corresponding broadcast signals only after the terminal initiates a broadcast request, and specifically supports two modes:
1. msg1 based broadcast request (SI request)
According to the 38.331 protocol, the base station side sends scheduling information schedulinglnfolist of other broadcast signals (such as SIB2 and SIB3) in the SI-schedulinglnfo field in SIB1, including information such as the period and transmission mode of each broadcast signal, for a broadcast signal with a transmission mode of "notbredcasting", if SI-RequestConfig is included in the SI-schedulinglnfo, the terminal triggers a broadcast request using Msg1 resources configured in SI-RequestConfig, as shown in fig. 1, for SIBs 2, SIB3 and SIBx, all of which have a transmission mode of "notbredcasting", the terminal can request the base station to send using Msg1 resources configured in SI-RequestConfig.
2. Msg3 based broadcast request (SI request)
According to the 38.331 protocol, if the SI-SchedulingInfo field does not contain SI-RequestConfig, the terminal requests broadcast transmission using Msg3 and Msg3 contains a rrcsystemminforequest message, as shown in fig. 2, which reports a rrcsystemminforequest message indicating that the base station is required to schedule SIB2, SIB3 and SIBx.
In the two schemes, for a broadcast request based on Msg1, a base station only allocates a preamble resource corresponding to Msg1, and different terminals only can request the same broadcast message type or combination, for example, SIB2 and SIB3 in schedulingInfoList are "notboradcasting", even if the terminal only needs SIB2, the base station transmits SIB2 and SIB3 after receiving Msg1, which causes resource waste and violates the principle of simple design, while a broadcast request based on Msg3 may accurately indicate the broadcast type or combination to be issued by the base station, but needs to increase the transmissions of Msg3 and Msg4, compared with a broadcast request based on Msg1, and also causes resource waste.
Therefore, the present invention provides a new design method for redesigning a broadcast request flow, fig. 3 is a schematic flow chart of the method for reducing the continuous presence of wireless signals provided by the present invention, as shown in fig. 3, the corresponding implementation subject is a base station, and the method includes:
101, determining SI-SchedulingInfo, and adding a preset number of broadcast message type subsets in the SI-SchedulingInfo, wherein each broadcast message type subset comprises at least one broadcast message type;
102, adding ra-preambleLength fields in the si-RequestConfig, wherein the ra-preambleLength fields are equal to the preset number, and the ra-preambleLength fields correspond to elements in the broadcast message type subset one by one;
103, sending an SIB1 message, and detecting the lead code of Msg 1;
and 104, if detecting that the broadcast message requests the special preamble code, transmitting the corresponding broadcast type to the terminal based on the broadcast message request special preamble code.
Specifically, the invention provides a broadcast request scheme based on a preamble, namely, a base station associates different broadcast types or combinations with different preambles in an SI-SchedulingInfo field of SIB1 one by one, a terminal selects different preamble resource transmissions Msg1 according to a broadcast message type expected to be acquired by the terminal, and the base station issues the corresponding broadcast types or combinations according to Msg 1. And since the number of preambles is limited, the base station periodically maintains the broadcast types or combinations requested by all terminals, maps the broadcast types or combinations most appeared to the limited preambles, and if the broadcast type or combination requested by the terminal is not in the SI-scheduling info field, the terminal uses the broadcast request based on Msg 3.
It should be noted that the terminal requesting the modification of the broadcast message flow includes: adding N subsets (schedulingInfoSubLists) of broadcast message types to the SI-schedulingInfo, each subset containing one or more broadcast message types; adding a ra-preambleLength field in the si-RequestConfig, wherein the ra-preambleLength field is equal to N, and N preamble resources starting from the ra-preambleStartIndex are in one-to-one correspondence with elements in the schedulingInfoSubList subset; after receiving the broadcast request dedicated preamble, the base station side finds the corresponding broadcast type subset and transmits the corresponding broadcast type, as shown in fig. 4.
Further, the base station maintaining the subset of broadcast message types includes: the base station determines a broadcast message type subset maintenance period T, counts broadcast message types or combinations requested by all terminals in the period, and sorts the broadcast message types or combinations according to occurrence times; the base station selects the first N types or combinations of broadcast messages according to the number N of configured dedicated preambles, and if the number N is different from the previous period, triggers a system message modification process and retransmits the SIB1 message, as shown in fig. 5.
The invention can accurately identify the broadcast request type of the terminal only by optimizing configuration on the basis of not increasing message flow and system overhead by the base station side, thereby realizing the simple design of the base station side, reducing the system power consumption and reducing the adjacent cell interference.
Based on the above embodiment, further include:
and if the rest preamble resource is detected, entering other preamble processing flows.
Recording the broadcast message type or combination requested by each terminal in a preset period;
after the preset period is finished, counting the times of occurrence of each broadcast message type or combination, and sequencing the times from large to small to obtain a sequencing result;
selecting the broadcast message types or combinations with the preset number arranged at the front according to the sorting result, and comparing the broadcast message types or combinations with the result of the previous period to obtain a comparison result;
if the comparison result is consistent, updating the SIB1 message and repeatedly executing the message recording process.
And if the comparison result is inconsistent, triggering a broadcast message modification flow and issuing a Paging message.
Specifically, the specific flow of the terminal requesting the broadcast message is shown in fig. 6:
step 301, adding a broadcast message type subset schedulingInfoSubList in SI-schedulingInfo by the base station side, wherein the broadcast message type subset schedulingInfoSubList comprises N broadcast messages or combinations;
step 302, the base station side adds a ra-preamblleLength field in the si-RequestConfig, wherein the ra-preamblleLength is equal to N and corresponds to elements in the schedulingInfoSubList subset one by one;
step 303, sending down an SIB1 message;
step 304, detecting a lead code of the Msg 1;
step 305, if detecting that the broadcast message requests a dedicated preamble, execute step 306, if detecting other preamble resources, execute step 307;
step 306, selecting the corresponding broadcast message type or combination for transmission;
step 307, other preamble processing flows.
The specific process of the base station maintaining the broadcast message type subset is shown in fig. 7:
step 401, a base station defaults to issue N broadcast message types or combinations;
step 402, the base station records the broadcast message type or combination requested by each terminal in a period T;
step 403, after the period is over, the base station counts the occurrence frequency of each broadcast message type or combination and sorts the broadcast message types or combinations from large to small;
step 404, the base station selects the first N types or combinations of broadcast messages according to the sorting result, compares the types or combinations with the result of the previous period, repeats step 402 if the types or combinations are consistent with the result of the previous period, otherwise executes step 405;
step 405, the base station triggers a broadcast message modification flow and issues a Paging message;
in step 406, the base station updates the SIB1 message and repeats step 402.
Fig. 8 is a second flowchart of the method for reducing the continuous presence of wireless signals according to the present invention, and as shown in fig. 8, the corresponding execution subject is a terminal, which includes:
receiving SIB1 message sent by base station, saving broadcast message type subset with preset number and ra-preambleLength field;
initiating a broadcast message request according to service requirements, and searching whether a matched broadcast message type or a matched broadcast message combination exists in the broadcast message type subset;
if the matched broadcast message type or combination is judged to exist, using a corresponding lead code resource and initiating an Msg1 message;
and if the Msg2 message returned by the base station is successfully received, receiving a broadcast message, otherwise, re-executing the corresponding lead code resource and initiating the Msg1 message according to the matched broadcast message type or combination.
Wherein, still include:
and if the matched broadcast message type or combination does not exist, selecting to initiate a broadcast message request based on the Msg 3.
Specifically, as shown in fig. 9, the terminal-side processing flow includes:
step 321, the terminal receives the SIB1 message and saves schedulinginfolist and ra-preambllelength;
step 322, initiating a broadcast message request according to the service requirement;
step 323, searching whether a matched broadcast message type or a matched broadcast message combination exists in the schedulingInfoSubList, if so, executing step 324, otherwise, executing step 326;
step 324, the terminal uses the corresponding lead code resource and initiates Msg1 according to the type or combination of the broadcast message;
step 325, if the terminal successfully receives the Msg2, which indicates that the base station successfully detects the Msg1, then 327 is executed, otherwise step 324 is executed;
in step 326, the terminal selects to initiate a broadcast message request based on Msg 3;
in step 327, the terminal receives the broadcast message.
