Description

Method for determining configuration parameters, sending scheduling request, and related equipment

The present invention relates to the field of communications, and in particular, to a method for determining configuration parameters, transmitting a scheduling request, and related devices. Background technique

In the Long Time Evolution (LTE) and LTE-A systems, the Scheduling Request (SR) is used by the user equipment (UE) when the uplink data needs to be sent but the uplink data is not sent. , request uplink resources to the network side.

Generally, the base station first configures an SR parameter for the UE, including a physical uplink control channel (PUCCH) for transmitting the SR, including a period of the SR, a code sequence used by the SR, and the like, and after receiving the configuration parameter, the UE When the SR is triggered, the UE sends an SR using the configured code sequence at the configured resource location, and requests the uplink resource from the base station. If the UE does not receive the uplink grant right of the uplink resource, the UE may also send the SR resource again in the next SR period until the uplink grant indicating the uplink resource is received or the maximum number of times is received, and the base station is based on the PUCCH resource. Energy detection is performed on different SR code sequences to determine whether a UE transmits an SR, and further allocates an uplink resource to the UE that has transmitted the SR.

And the first base station sends the SR resource time position information allocated to the first cell UE (such as the edge area UE) to the third base station of the neighboring cell, so that the third base station is configured according to the SR resource time. The location information determines that the SR resource time position allocated by the third cell to the UE (such as the edge area UE) is subframe 2 and subframe 7 of each radio frame, or the first base station is allocated to the first cell UE (such as the edge area UE). The SR resource frequency location information is sent to the third base station of the neighboring cell, so that the third base station determines, according to the SR resource frequency location information, the SR resource frequency location allocated by the third cell to the UE (such as the edge area UE) for each Physical resource block 2 and subframe 47.

Uplink physical resource set information, and/or code sequence set information, and/or transmit power information, and/or transmit power threshold information, and/or load parameters of the uplink physical resource set, and/or uplink The load threshold of the physical resource set, where the uplink physical resource set information includes: time domain location information of the uplink physical resource set, and/or, frequency domain location information of the uplink physical resource set.

22. A method of sending a scheduling request, characterized by including:

When the user equipment UE triggers the scheduling request SR, the UE determines whether it is in the preset sending state;

If it is in the preset sending state, the UE sends the SR;

If it is not in the preset sending state, the UE does not send the SR.

23. The method according to claim 22, characterized in that when the user equipment UE triggers the scheduling request SR, before the step of determining whether the UE is in the preset transmission state, the step further includes: the UE receives the message sent by the base station. configuration parameters;

The UE determines whether to trigger the step of determining whether the UE is in a preset sending state when the user equipment UE triggers a scheduling request SR according to the configuration parameter.

24. The method according to claim 22 or 23, characterized in that when the preset transmission state is the DRX activation state, the determination of whether it is in the preset transmission state specifically includes:

Determine whether the DRX ON timer, DRX inactivation timer, DRX retransmission timer, or MAC layer contention resolution timer is running;

25. The method according to claim 22 or 23, wherein when the preset transmission state is the DRX ON state, the determination of whether it is in the preset transmission state specifically includes:

Determine whether the DRX ON timer is running;

When the DRX ON timer is running, it is determined to be in the DRX ON state.

26. A method of sending a scheduling request, characterized by including:

The base station sends configuration parameters to the UE, and the configuration parameters are used to cause the UE to perform a preset operation. The preset operation is to determine whether the UE is in a preset sending state when the UE triggers a scheduling request SR.
