Problems solved by technology

[0014] The bit overhead of the above-mentioned first method of sending the user equipment identifier in the control signaling is relatively large, because it explicitly transmits the user identifier; the above-mentioned second method of sending the user equipment identifier in the control signaling The bit overhead of the method is relatively small, but it is only applicable to the case where the length of the user identification is less than or equal to the length of the CRC, and the possibility of false detection increases due to this method

Embodiment

[0092] This section presents two embodiments of the invention. In order to avoid making the description of this patent too lengthy, in the following description, detailed descriptions of functions or devices that are well known to the public are omitted.

[0093] These two embodiments respectively take the paging channel and the random access channel as examples to illustrate two application scenarios of the present invention, and the method of the present invention can also be used for processing user identification information and user information in other channels.

no. 1 example

[0095] This embodiment gives an application example of the present invention for transmitting paging information.

[0096] In this embodiment, it is assumed that the network adds CRC to the paging information such as the user ID and paging reason of each user equipment currently to be paged, and then collects information of each user equipment into one information block for encoding and transmission. It is assumed here that the length of the CRC is 16 bits.

[0097] Figure 7 is an example of the process of the network processing the paging information of a user equipment paging with IMSI in the present invention. Here, it is assumed that the network takes all the numbers of the MCC of the IMSI and the first number of the MNC as the second part of the IMSI, and takes All digits of the MSIN and the second digit of the MNC are used as the first part of the IMSI. As shown in Figure 7, first the network calculates a 16-bit CRC (701) according to all numbers of the MSIN in the IMSI...

Abstract

An equipment and method for sending user equipment identification and user information comprises the following steps: the network transfers a first part bit display identified by the user equipment; the network transfers a second part bit identified by the user equipment through added CRC bit implicit. Using the method of the present invention, it can decrease bit spending while sending information, and reduce the probability of error detection at the same time.

Description

technical field [0001] The present invention relates to a wireless communication system, and more specifically relates to a device and method for sending user equipment identifiers and user information in the wireless communication system. Background technique [0002] Now, the 3GPP standardization organization has begun to carry out long-term evolution (LTE, Long Term Evolution) of its existing system specifications. Among the many physical layer transmission technologies, the downlink transmission technology based on Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) and the uplink transmission technology based on Single Carrier Frequency Division Multiple Access (SCFDMA, Single Carrier Frequency Division Multiple Addressing) Technology is a hot topic of research. OFDM technology is essentially a multi-carrier modulation communication technology. Its basic principle is to decompose a high-rate data stream into several low-rate da...
