Abstract
A method and terminal equipment for delaying a scheduling request and a Base Station (BS) thereof are provided by the embodiments in the present invention. The method includes: while there is uplink data on a logical channel, according to the control parameter indicating whether to permit a delay of the logical channel, a terminal equipment determines whether to permit to delay the triggering of a buffer status report; the buffer status report is not triggered while the delay is permitted, so as to delay the triggering of the scheduling request to the terminal equipment. With the embodiments of the present invention, a scheduling request of triggering or transmitting is able to be delayed, so that the interference between an Industrial Scientific Medical(ISM) system and a Long Term Evolution (LTE) system can be avoided.
Description
Method, terminal device and the station technology field of delay dispatching request
The present invention relates to a kind of communications field, more particularly to a kind of delay dispatching request（SR, Scheduling Request) method, terminal device and base station.Background technology
In order to realize access network that user is ubiquitous, terminal device needs to install many set transceivers to access different networks.For example, terminal device can be provided with Long Term Evolution simultaneously（LTE, Long Term Evolution) system, industrial scientific medical（ISM, Industrial Scientific Medical) system（Such as WiFi, bluetooth BlueTooth）Transceiver.Because many set transceiver distances are very near in same terminal device, the power of a system transmitter may be far above the power of another system receiver.
Fig. 1 gives the example of an interference co-existence, as shown in Figure 1, terminal device may include LTE systems, gps system and bluetooth/WiFi system, and LTE system may produce interference to bluetooth/WiFi system, and bluetooth/WiFi system may also produce interference to LTE system.If the working band interval of different system is farther out, the control transmission signal docking collection of letters number interference caused can be very good by filtering technique.
However, for some scenes, for example, when different system in same terminal device working frequency range closely when, current filtering technique, which is not enough to provide effective interference, to be avoided.Therefore for such scene, in order to which interference when realizing that multiple systems transceiver coexists in terminal device is avoided, in addition to filtering technique, in addition it is also necessary to consider other methods.
At present, 3GPP mainly considers the scene of following coexistence of systems.
(1) LTE and WiFi system coexist
(2) LTE and Bluetooth coexistence of systems
(3) LTE and GLONASS（GNSS, Global Navigation Satellite System) coexist
And in the scene that said system coexists, it may appear that interference problem include：
(1) in the Band 40 of LTE system, the signal of LTE system sends that the signal of ISM systems can be received and interfered；
(2) in the Band 40 of LTE system, the signal of ISM systems sends that the signal of LTE system can be received and interfered；
(3) in the Band 7 of LTE system, the signal of LTE system sends that the signal of ISM systems can be received and interfered；
(4) in the Band 7/13/14 of LTE system, the signal of LTE system sends that the signal of GNSS system can be received and interfered
In order to avoid the mutual interference under above-mentioned scene, one of which method is to use time-multiplexed mode, and the signal of two different systems is sent and signal is received and separated from the time.Fig. 2 is example schematic of the terminal device in different reception LTE system signals and transmission WiFi or Bluetooth signal.
At present, 3GPP defines two kinds and realizes time-multiplexed method.Including：
(1) method reserved based on HARQ (HARQ) process.The time relationship for the HARQ processes that this method is defined according to LTE system, is LTE system reserved part subframe, and remaining subframe is distributed into ISM systems, i.e., in remaining subframe, device end can carry out sending and receiving for ISM system datas.
(2) method of discontinuous reception (DRX) based on LTE system.This method utilizes the DRX mechanism of current LTE systems, and after the LTE transceiver of terminal device enters resting state, terminal device can carry out sending and receiving for ISM system datas.
In order to realize this method, terminal device needs to send the cycle of its desired LTE systems and ISM systems work to base station and the working time of LTE system and the working time of ISM systems (hereafter known as TDM patterns) within the cycle, and some other auxiliary informations, for example, interference type, coexistance model etc..The TDM patterns of LTE system and ISM coexistence of systems are finally then determined, and realize the TDM patterns by appropriate configuration DRX parameter by base station.Fig. 3 illustrates the TDM patterns that a terminal device is advised to base station.Fig. 4 illustrates a TDM pattern according to the suggestion, the configuration for the DRX that base station is finally determined.
But, during the present invention is realized, inventor has found that the defect of prior art is：In the case where LTE and ISM coexist, when using DRX mechanism, if terminal device has come into ISM working conditions, after the upstream data for having LTE system is reached, if triggering dispatch request or Stochastic accessing immediately according to current LTE method, it can so cause ISM systems and LTE systems to work simultaneously, therefore interference from each other can be caused.
