Problems solved by technology

Moreover, when all UEs accessing a certain serving cell only have uplink scheduling, the UE will not send data in the configured PUCCH ACK / NACK position. At this time, the RB in the PUCCH ACK / NACK position is not actually used, resulting in The waste of this part of RB time-frequency resources limits the traffic of uplink services

Embodiment 1

[0045] see figure 2 , which shows a method for scheduling PUCCH resources provided by an embodiment of the present invention, the method may include:

[0046] S201: The base station side determines that the base station side and the uplink scheduling UE are close point scenarios within the current TTI according to the configuration status of the serving cell for the same-frequency neighbor cell and the path loss of the uplink scheduling UE;

[0047] S202: The base station side determines the PUCCH RB resources to be reserved according to the uplink scheduling state of the UE, and schedules the PUCCH RB resources other than the reservation to the PUSCH.

[0048] figure 2 The shown solution schedules PUCCH RB resources to PUSCH through the base station side, thereby increasing the number of RBs available for PUSCH and achieving the purpose of increasing the uplink rate

[0049] Exemplarily, for step S201, it may specifically include:

[0050] When the serving cell is config...

Embodiment 2

[0067] Based on the same technical idea of ​​the foregoing embodiments, see image 3 , which shows a detailed flow of scheduling PUCCH resources provided by an embodiment of the present invention, which may include:

[0068] S301: The base station scheduler counts dynamically scheduled UEs in downlink subframes sent by the downlink scheduling module in each TTI;

[0069] The specific statistical method is to obtain the union of UEs dynamically scheduled in the downlink subframe within the downlink binding window; then enter step S302;

[0070] S302: The base station scheduler judges whether the current TTI is an uplink scheduling subframe according to the scheduling sequence, and if so, proceeds to step S303, otherwise proceeds to step S313;

[0071] S303: The base station scheduler judges whether the serving cell is configured with a co-frequency neighbor cell, and if so, proceeds to step S304, otherwise proceeds to step S305;

[0072] S304: The base station scheduler judge...

Embodiment 3

[0086] Based on the same technical idea of ​​the foregoing embodiments, see Figure 4 , which shows the structure of a base station 40 provided by an embodiment of the present invention, the base station 40 may include: a scene determination module 401, a resource reservation module 402, and a resource scheduling module 403, wherein,

[0087] The scenario determination module 401 is configured to determine the distance between the base station 40 and the uplink scheduling UE within the current transmission time interval TTI according to the configuration state of the serving cell for the same-frequency neighbor cell and the path loss of the uplink scheduling user equipment UE. close-up scene

[0088] The resource reservation module 402 is configured to determine the PUCCH resource block RB resources that need to be reserved according to the uplink scheduling state of the UE;

[0089] The resource scheduling module 403 is configured to schedule the PUCCH RB resources other tha...

Abstract

The embodiment of the present invention discloses a PUCCH resource scheduling method and device; the method may include: the base station side determines the current PUCCH resource scheduling status of the base station side according to the configuration status of the serving cell for the same-frequency neighbor cell and the path loss of the uplink scheduling user equipment UE. The transmission time interval TTI is close to the uplink scheduling UE; the base station side determines the PUCCH resource block RB resources that need to be reserved according to the uplink scheduling status of the UE, and will reserve PUCCH RB resources Scheduled to the physical uplink shared channel PUSCH.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a physical layer uplink control channel (PUCCH, Physical Uplink Control CHannel) resource configuration method and device. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, the PUCCH is mainly used to carry uplink L1 / L2 control information (UCI, Uplink Control Information) to support uplink and downlink data transmission. Specifically, UCI may include a scheduling request (SR, Scheduling Request), a positive acknowledgment or a negative acknowledgment of a hybrid automatic transmission request (HARQ ACK / NACK, Hybrid Automatic Repeat request ACKnowledgment / NegativeACKnowledgment) and channel state information (CSI, Channel State Information ) three parts. exist figure 1 In the position diagram of the PUCCH resource block (RB, Resource Block) shown in the frequency domain, it can be concluded that the PUCCH RB is located at both ...
