Embodiment 1

[0026] refer to figure 2 , shows a flow chart of steps of a time slot scheduling method according to Embodiment 1 of the present invention.

[0027] The time slot scheduling method of the present embodiment includes the following steps:

[0028] Step S202: the base station judges whether the amount of downlink data to be transmitted is less than or equal to a set threshold, if yes, execute step S204; if not, execute step S210.

[0029] In this step, the base station judges whether the amount of downlink data of the HSDPA service to be transmitted in the TD-SCDMA system is small, that is, whether it is less than or equal to a set threshold. Wherein, the setting threshold can be appropriately set by those skilled in the art according to the actual situation, and the data transmission volume of not more than one time slot resource is a principle.

[0030] Step S204: If the amount of downlink data to be transmitted is less than or equal to the set threshold, the base station wi...

Embodiment 2

[0039] refer to image 3 , shows a flow chart of steps of a time slot scheduling method according to Embodiment 2 of the present invention.

[0040] The time slot scheduling method of the present embodiment includes the following steps:

[0041] Step S302: the base station judges whether the BRU of the downlink data to be transmitted is less than or equal to 16, if yes, execute step S304; if not, execute step S312.

[0042] In this embodiment, the base station judges whether the downlink data to be transmitted is data with a small data volume by judging the BRU of the downlink data to be transmitted. When the BRU is less than or equal to 16, the downlink data transmission can be completed in one time slot. Therefore, it can be determined that when the BRU is less than or equal to 16, the downlink data to be transmitted is data with a small amount of data. The size of the data to be transmitted is judged by judging the BRU, which is simple to implement, saves the implementati...

Embodiment 3

[0057] refer to Figure 4 , shows a flow chart of steps of a time slot scheduling method according to Embodiment 3 of the present invention.

[0058] This embodiment is based on the premise that in the TD-SCDMA system, the downlink data of the HSDPA service to be transmitted is small data volume data, such as the data volume of BRU less than or equal to 16, and the terminal in this embodiment uses UE (User Equipment, user equipment ) as an example.

[0059] The time slot scheduling method of the present embodiment includes the following steps:

[0060] Step S402: After receiving the downlink data from the RNC, the MAC layer of the base station converts the data format through the FP, and caches it in the base station in the form of Mac_hs PDU data.

[0061] Step S404: the base station waits for a timing interrupt to perform time slot resource allocation and scheduling.

[0062] Step S406: the base station judges whether the TTI has arrived, if yes, execute step S408; if not...

Abstract

The present invention provides a time slot scheduling method and device, wherein the time slot scheduling method includes: the base station determines whether the amount of downlink data to be transmitted is less than or equal to a set threshold; if so, the base station determines whether the amount of downlink data to be transmitted is less than or equal to a set threshold; if so, the base station The channel quality indicator CQI fed back by the terminal corresponding to the downlink data and the transmission capability corresponding to the actual physical resources of the physical layer of the base station allocate the first time slot resource to the terminal; the base station uses a pre-generated random offset value, adjust the allocated first time slot resource to the second time slot resource, wherein the random offset value is less than the number of time slots that can be allocated by the base station in this time slot scheduling; the base station will The second time slot resource is scheduled to the terminal for the terminal to transmit the downlink data. Through the present invention, the situation of concentrated time slot resource allocation is effectively alleviated.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a HSDPA (High Speed ​​Downlink Packet Access) service in a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system Time slot scheduling method and device. Background technique [0002] For the resource allocation process in the HSDPA service process in the existing TD-SCDMA system, the 3GPPTS 25.221 protocol only defines the resource format, the concept of the time slot code channel, the calculation formula for the corresponding data block size of the channel type, and the code channel time slot configuration, etc. , did not give the specific allocation process and method. [0003] In the implementation operation, a currently existing resource allocation process implementation scheme is as follows: figure 1 As shown, it includes: step S102, the base station side MAC layer will receive the downlink data resources from the RNC (Radio Network Contr...
