 In order to support uplink high-speed data services, the 3rd Generation Partnership Project (3GPP) introduced High-Speed Uplink Packet Access (HSUPA) technology in the R7 protocol, and applied the uplink enhancement technology of HSUPA to TD-SCDMA. Adapting code modulation and hybrid request retransmission can effectively improve the good support for uplink data services, thereby improving the uplink throughput of TD-SCDMA. Among them, in 3GPP, TD-SCDMA is a single carrier TD-SCDMA. Then, the uplink enhancement technology is applied in TD-SCDMA, and the uplink enhanced access method is also a single-carrier uplink enhanced random access method.

 With the development of wireless communication technology, the characteristics of N-frequency and multi-carrier are introduced in TD-SCDMA. Correspondingly, the existing TD-SCDMA includes N-band TD-SCDMA and multi-carrier TD-SCDMA. The common features of these two TD-SCDMA are: A TD-SCDMA cell operates at multiple carrier frequencies. One frequency point is used to send a broadcast message, which is called a primary carrier, and other frequency points are not used to send a broadcast message, which is called a secondary carrier. The distinguishing characteristics of the two TD-SCDMA are: In the N-frequency TD-SCDMA, one terminal can only receive data on one carrier at the same time, and the peak rate is relatively low; while in multi-carrier TD-SCDMA, one terminal can simultaneously Receiving data from multiple carriers, the peak rate is relatively high.

 detailed description

The core idea of the present invention is: The E-RUCCH transmitted by the terminal can be transmitted not only on the primary carrier but also on the secondary carrier. The base station receives the random access request on the corresponding carrier, and sends the feedback information, thereby completing the uplink enhanced random access. In this way, on the one hand, the primary carrier and the secondary carrier jointly share the access requests of all frequency points in the TD-SCDMA cell, and can support more access to the number of uplink enhanced users, thereby improving uplink enhanced random access. ability. On the other hand, all uplink enhanced users in the TD-SCDMA cell can use the primary carrier or the secondary carrier to send a random access request, so the collision probability of the uplink pilot code is small, thereby reducing the random access collision. And random access delay The probability of the problem.

 The present invention will be further described in detail below with reference to the accompanying drawings.

 A TD-SCDMA random access method, as shown in FIG. 1, the method includes the following steps: Step 101: A terminal selects to send an uplink pilot channel to a base station on a primary carrier or a secondary carrier according to a pre-assigned uplink pilot code. .

 The manner in which the terminal selects the primary carrier or the secondary carrier includes: a fixed selection manner, a randomly selected manner, or a manner of selecting according to a predefined probability.

 Step 102: The terminal receives a fast access indication channel FPACH returned by the base station.

 The processing of the step 102 specifically includes the following steps, as shown in FIG. 2:

 Step 1021: The base station determines that the access channel to be initiated is PRACH or E-RUCCH; if it is determined to be PRACH access, step 1022 is performed; if it is determined to be E-RUCCH access, step 1023 is performed.

 Here, the determining manner that the access channel to be initiated is the PRACH or the E-RUCCH in the step 1021 includes: determining, by the base station, the uplink pilot code carried by the received uplink pilot channel, or only receiving the received uplink The carrier on which the pilot channel is located is used for judgment.

 Specifically, since the uplink pilot code is divided by the radio network controller, the radio network controller divides the eight uplink pilot codes available in one TD-SCDMA cell into two groups, one for the PRACH, and the other for the PRACH. One set is for E-RUCCH. And, broadcast in the broadcast message of TD-SCDMA. Thereafter, the terminal reads two sets of uplink pilot codes from the broadcast, and selects among the two sets of uplink pilot codes that are allocated in advance according to the PRACH or E-RUCCH to be transmitted. Therefore, the base station can determine that the received uplink access channel is a PRACH or an E-RUCCH according to the received uplink pilot code.

 Step 1022: On the current carrier corresponding to the uplink pilot channel, the base station returns the FPACH to the terminal, and then performs step 103. Correspondingly, the random access request in the subsequent step 103 is a normal random access request.

 Step 1023: On the current carrier corresponding to the uplink pilot channel, the base station returns the FPACH to the terminal. Correspondingly, the random access request in the subsequent step 103 is an uplink enhanced random access request.

 Step 103: The terminal selects to send a random access request on the primary carrier or the secondary carrier, and the base station allocates the wireless resource to the terminal on the current carrier corresponding to the sending the random access request.

The manner in which the terminal selects the primary carrier or the secondary carrier includes: a fixed selection mode, and a random selection The manner of selecting, or selecting according to a predefined probability, and the carrier selected in this step may be the same as the carrier in step 101, or may be different.

 Because the difference of the uplink access to be initiated is determined in the foregoing steps 1021-1023, the corresponding random access request in step 103 is different, and whether the random access request is the initial random access request may also result in step 103. The specific implementation process is different. Here, the specific implementation process of step 103 includes the following two cases.

 In the first case, it can be known from step 1022 that the base station determines that the uplink access channel to be initiated is a PRACH. Then, the corresponding random access request in step 103 is a normal random access request, and the ordinary random access request is a terminal. The initial random access request, the step 103 includes the following steps: Step 1031a: The terminal initiates an RRC connection setup request on the PRACH, and the base station returns the RRC connection setup complete information to the terminal, and is the terminal on the current carrier corresponding to the PRACH. Allocating radio resources; The terminal enters the RRC connection state.

 Step 1031b: After the terminal enters the RRC connection state, and the re-initiated random access request is an uplink enhanced random access request, the terminal selects to send an uplink pilot channel to the base station on the primary carrier or the secondary carrier, and receives the Determining the FPACH channel returned by the base station; on the carrier corresponding to the sending the random access request, the terminal sends the uplink enhanced random access request on the E-RUCCH, on the current carrier corresponding to the E-RUCCH The base station allocates radio resources to the terminal. Here, the base station allocates radio resources to the terminal, including: after returning the access permission information to the terminal on the E-AGCH, the base station allocates the corresponding uplink radio resource to the terminal, and schedules the terminal.

 Correspondingly, after step 1031b, the method further includes:

 Step 104: The terminal sends an uplink enhanced dedicated channel (E-DCH) according to the received uplink radio resource and scheduling information on the E-AGCH, and sends uplink data on the E-DCH.

 In the second case, it can be known from step 1023 that the base station determines that the uplink access channel to be initiated is an E-RUCCH, and then the corresponding random access request in step 103 is an uplink enhanced random access request, and the uplink enhanced request The random access request is an initial random access request of the terminal, and step 103 includes the following steps:

 Step 1032a: The terminal initiates an RRC connection setup request on the PRACH, and the base station returns an RRC connection setup complete message to the terminal, and allocates a radio resource to the terminal; the terminal enters an RRC connection state.

Step 1032b: After the terminal enters the RRC connection state, the random access request to be initiated is uplink. The enhanced random access request, the terminal selects to send an uplink pilot channel to the base station on the primary carrier or the secondary carrier, and receives the FPACH channel returned by the base station; on the carrier corresponding to the random access request, the terminal The uplink enhanced random access request is sent on the E-RUCCH, and the base station allocates radio resources to the terminal on the current carrier corresponding to the E-RUCCH.

 Here, on the E-RUCCH channel, the terminal uses the same radio resource assigned to the PRACH as the base station, or uses the radio resource pre-configured by the base station for the E-RUCCH.
