Abstract
Embodiments of this disclosure provide a method for selecting a random access resource and a terminal. The method includes: determining first information; and determining a random access resource based on a correspondence between first information and random access resources; where the first information includes any one of the following: a signal, an uplink carrier, or a random access procedure type.
Claims19
A method for selecting a random access resource, comprising:
- determining first information according to a rule for selecting a random access resource;
- and
- determining a random access resource based on a correspondence between first information and random access resources;
- wherein
- the first information comprises a signal;
- wherein the rule for selecting the random access resource comprises:
- determining an uplink carrier according to a rule for selecting the uplink carrier, determining a random access procedure type according to the uplink carrier and a rule for selecting the random access procedure type, and determining the signal according to the random access procedure type and a rule for selecting the signal;
- wherein the random access procedure type comprises one or more of the following:
- 2-step random access procedure or 4-step random access procedure;
- wherein the rule for selecting the uplink carrier comprises:
- selecting the uplink carrier based on a relationship between Reference Symbol Received Power (RSRP) of a downlink signal and an RSRP threshold;
- or
- selecting, based on a measured result of RSRP for a cell, the uplink carrier corresponding to the cell;
- wherein the rule for selecting the random access procedure type comprises one or more of the following:
- selecting the random access procedure type based on an RSRP threshold;
- selecting the random access procedure type based on a size of data in uplink transmission;
- selecting the random access procedure type based on an RSRP threshold and a size of data in uplink transmission;
- selecting the random access procedure type based on a random number;
- selecting the random access procedure type based on a designated preferred random access procedure type;
- wherein the rule for selecting the signal comprises selecting the signal based on a measurement threshold of the signal.
