Random access method and related device

A communication method, comprising:

• receiving, by a network device, a second message sent by a terminal device, wherein the second message is used for requesting the network device to establish a wireless connection to the terminal device, the second message includes a second polarization parameter, and a first identity is obtained using a first formula in association with the second polarization parameter;
• determining, by the network device, a first polarization parameter based on the second message, wherein a second identity is obtained using the first formula in association with the first polarization parameter;
• determining, by the network device, whether the terminal device satisfies a match condition in association with determining whether the second identity is the same as the first identity;
• and
• sending, by the network device, a connection response to the terminal device based on the terminal device satisfying the match condition, wherein the connection response comprises information for the first polarization parameter, and the connection response indicates the terminal device to access the network device, wherein
• the first identity is a first random access radio network temporary identifier (RA-RNTI), and
• the first formula is expressed in the following form:
• RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2×polarization_id.

A communication apparatus, comprising:

• a processor;
• and
• a memory configured to store computer readable instructions that, when executed by the processor, cause the communication apparatus to:
• determine a second polarization parameter used in association with the apparatus sending a first message;
• obtain, using a first formula, a first identity based on the second polarization parameter:
• send the first message to a network device using the second polarization parameter, wherein the first message is used for requesting the network device to establish a wireless connection to the apparatus;
• receive a connection response sent by the network device, wherein the connection response comprises information for a first polarization parameter;
• obtain, using the first formula, a second identity based on the information for the first polarization parameter included in the connection response;
• determine whether the apparatus satisfies a match condition in association with determining whether the second identity is the same as the first identity;
• and
• access the network device in response to the apparatus satisfying the match condition, wherein
• the first identity is a first random access radio network temporary identifier (RA-RNTI), and
• the first formula is expressed in the following form:
• RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2×polarization_id.
