- the network side requests the terminal to report through a request message
- the terminal actively reports
- the network side After the terminal informs the network that it has recorded random access related information, the network side then requests the terminal to report through a request message.
- the information related to random access is carried by at least one of the following messages:
- Target message for example, the target message is a newly defined message, etc., which is not specifically limited here;
- the above-mentioned random access related information can help the network side to configure a reasonable random access type (2-step, 4-step, CBRA, CFRA) on the appropriate carrier (SUL/UL) and BWP And related parameters (RSRP threshold for 2-step random access, number of attempts for 2-step random access, etc.).
- a reasonable random access type (2-step, 4-step, CBRA, CFRA) on the appropriate carrier (SUL/UL) and BWP And related parameters (RSRP threshold for 2-step random access, number of attempts for 2-step random access, etc.).
- the network side equipment After the network side equipment receives the random access related information reported by the terminal, it can perform corresponding network coverage and parameter optimization, such as optimizing the random access type supported by the terminal on SUL, UL, and BWP, and the quality of 2-step random access
- the threshold, the threshold of the number of attempts of 2-step random access, and the coverage optimization corresponding to message A include beam-level and cell-level coverage optimization.
- the network side can locate the random access scenario and type that needs to be optimized.
- the reason may be that the random access preamble code of the dedicated random access resource allocated to the terminal collides with the neighboring cell, or the 2-step CFRA RSRP configured for the terminal
- the threshold is too low, and the RSRP detected by the terminal meets the threshold configured on the network side, but msg A is not successfully detected on the base station side (where the base station may successfully decode the preamble code and reply to the terminal with a fallback indication; it may also be connected to the preamble.
- the network side can coordinate the preamble group with the neighboring cell to avoid collisions (for example, when the preamble code is successfully decoded), or increase the terminal's 2-step CFRA RSRP threshold (for example, when the preamble code is not successfully decoded) ) To improve the success rate of msgA detection on the network side.
- the network side can determine the length of time for the terminal to receive the corresponding feedback after sending msg A, so as to determine whether certain scenarios, especially CFRA, which requires high latency, should be improved.
- the feedback speed of the base station in the scenario prevents the terminal from waiting for feedback from the network side for a long time.
- the terminal initiates 2-step CBRA and detects a collision, and the network side receives similar reports from multiple terminals, the network side judges that it may be assigned to 2-step
- the number of preambles in CBRA is too small, resulting in a high collision probability, or the RSRP threshold configured on the network side for 2-step CBRA is too low, resulting in too many terminals performing 2-step CBRA, and the collision probability is high.
- the network side can adjust the RSRP threshold and/or preamble group for the terminal to perform 2-step CBRA.
- the network side can further locate which carrier (SUL or ordinary UL) the random access problem occurs on, and which BWP (the network side can be based on location and bandwidth, sub-carrier To determine the specific BWP with information such as the interval SCS), the network side can adjust the configuration of the random access resource of the corresponding carrier or BWP, or adjust the network side’s indication of the terminal to select SUL or UL (when the SUL or UL on the carrier is UL is indicated by the network side, not in the form of configuring the threshold);
- the network side can determine whether it should support the terminal to fall back to the 4-step RACH. For example, in the edge coverage area on a certain carrier or BWP, the RSRP measured by the terminal is not very high. Therefore, the probability of failure of the 2-step RACH of the terminal in the edge area is high. If the terminal is not supported to fall back to the 4-step RACH, the terminal will not be able to complete the random access process.
- the network side can determine whether the number of 2-step RACH attempts that the terminal is allowed to try is properly configured. If the number of times N is configured too large, it will cause the terminal to try too many 2-step RACHs, and eventually fall back to 4-step RACH, which will cause the terminal to try 2-step RACH for too long; if the number of times N is configured too much If it is small, it will cause the terminal to easily produce a fallback process, so that there are fewer terminals that can benefit from the 2-step RACH process.
