Problems solved by technology

In the time-division synchronous code division multiple access technology TD-SCDMA system, the uplink and downlink time slot switching points are variable, if the practice of using 5 bits to fix the indication will cause waste of information bits, in some time slot configurations Under the structure, the efficiency of signaling transmission will decrease, resulting in waste of transmission resources and increasing the transmission load of control information.

[0040] In this embodiment, the system configures a fixed number of N bits of time slot occupation information indication bits in the time slot resource occupation indication information structure of the HS-SCCH channel. Such as figure 2 As shown, in this embodiment, N=5, and the 5-bit information is transmitted to one UE, but the system can simultaneously send different time slot occupancy information to multiple UEs. When the bit corresponds to a certain time slot, if the value is 1, it means that the time slot is occupied; if the value is 0, it means that the time slot is not occupied, and of course the opposite is also possible. Alternatively, this bit may be invalid, ie not indicate the occupancy status of any slot.

[0041] The method for dynamic indication of time slot occupation in this embodiment includes the following steps:

[0042] Step 1: Set the occupancy of each downlink time slot that may be occupied under each combination of uplink and downlink time slot con...

[0062] In this embodiment, the HS-SCCH channel adopts a variable-length time slot resource occupancy indication information structure, and the time slot occupancy dynamic indication method includes the following steps:

[0063] Step A: Set the length of the HS-SCCH channel time slot resource occupancy indication structure under each combination of uplink and downlink time slot configuration structure information and the number of carriers, and each possible occupied downlink time slot in this structure In the corresponding information bit, save the dynamic association relationship in NodeB and UE;

[0064] In this embodiment, the length of the HS-SCCH channel time slot resource occupancy indication structure is equal to the number of configured downlink time slots, and each information bit corresponds to one downlink time slot in turn.

[0065] This embodiment preferably adopts an association method in which the available downlink time slots and the information bits are in seq...

Abstract

The invention discloses a method for a dynamic indicating high speed downlink grouping access time slot occupation which is applied to a multicarrier TDD system. Firstly, with the combination of each uplink and downlink time slot allocation structure information and carrier number prearranged, a corresponding information bit indicating manner of each downlink time slot occupied condition in an HS-SCCH channel time slot resource occupation indicating structure is saved at a node B and a mobile terminal UE; the uplink and downlink time slots allocation structure and the carried number information of the district are obtained by the node B and the UE; after the HS-SCCH code track resource is distributed by the node B to a UE, the corresponding information bit value of the information structure is arranged according to the downlink time slot occupation condition; the information of the structure and the carrier number is allocated by the UE according to the uplink and downlink time slot resource, and the corresponding information bit indicating manner in the downlink time slot occupation condition is ensured; the downlink time slot occupation condition is obtained according to the corresponding information bit value. The method for the dynamic indicating high speed downlink grouping access time slot occupation can indicate the occupation condition of a TSO time slot and improve the service efficiency of the time slot occupation indicating information.

Description

technical field [0001] The invention relates to a dynamic indication method for time slot occupation of high-speed downlink packet access, in particular to a dynamic indication method for time slot occupation of a multi-carrier high-speed downlink packet access system in the communication field. Background technique [0002] 3GPP (Third Generation Collaborative Project Organization) introduced the high-speed downlink packet access (HSDPA: Highspeed oownlink PacketAccess) feature in Releases 5 of the 3G (third-generation mobile communication technology) specification, with the purpose of providing higher-speed downlink packet services , to increase the downlink capacity. Based on the UMTS (Universal Mobile Telecommunications System) R4 architecture, HSDPA achieves the above goals by introducing technologies such as Adaptive Modulation and Coding (AMC) and Hybrid Automatic Retransmission Request (HARQ). [0003] UTRAN (UMTS Terrestrial Radio Access Network) defines a series o...
