Problems solved by technology

If the RB resources allocated to the user are also indicated in the same way in the sTTI, since the sTTI duration is shorter, a legacy TTI generally includes multiple sTTIs, and more resources need to be occupied to carry these RB allocation information bits, resulting in Large overhead of downlink control information

Embodiment 1

[0041] Embodiment 1: Acquiring the preset first duration value and the second duration value.

[0042] In this embodiment, on the one hand, the first duration value of the longer first period and the second duration value of the shorter second period may be actual duration values ​​preset by the standard, so that the base station does not need to determine The terminal is notified of the value of the first duration and the value of the second duration, which reduces the power consumption of the base station.

Embodiment 2

[0043] Embodiment 2: configuring the first duration value and the second duration value, and notifying the terminal of the first duration value and the second duration value.

[0044] In this embodiment, on the other hand, the first duration value of the longer first period and the second duration value of the shorter second period may be the actual duration values ​​configured by the base station, so they can be adjusted according to actual needs The first duration value and the second duration value are to meet individual needs, and further, the base station is required to inform the terminal of the configured first duration value of the first cycle and the second duration value of the second cycle, so as to realize effective indication of resource allocation .

[0045] Further, the first duration value is an integer multiple of the second duration value.

[0046] In this embodiment, the first duration value of the longer first period can be configured as an integer multipl...

Abstract

The present invention proposes a resource allocation indication method, a resource allocation indication device, and a base station, wherein the resource allocation indication method includes: in an LTE system using sTTI, determining the first duration value of the first cycle and the value of the second cycle The second duration value, wherein the first duration value is greater than the second duration value; the first resource allocation information is sent to the terminal according to the first cycle, and the second resource allocation information is sent to the terminal according to the second cycle sent to the terminal, wherein the first resource allocation information is used to indicate the number of the resource bandwidth group to which the resource block allocated for the terminal belongs, and the second resource allocation information is used to indicate that the resource block is allocated in The resource block number in the resource bandwidth group. Through the technical scheme of the invention, the overhead of downlink control information of the LTE system adopting sTTI can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular, relates to a resource allocation indication method, a resource allocation indication device and a base station. Background technique [0002] At present, with the development of the mobile Internet, a large number of application services satisfying various specific functions have emerged. Some of these services have lower requirements on data latency, such as sending and receiving emails, downloading movies, etc.; but some other services have strict requirements on data latency, such as online games, snapping up, grabbing red envelopes, etc. These services usually require The delay of user data should be as short as possible. In an LTE (Long Term Evolution, Long Term Evolution) system, a Transmission Time Interval (TTI, Transmission Time Interval) is an important index that affects user data delay. The current LTE system uses a transmission time interval of 1 m...
