Description

Physical uplink control channel resource allocation method, base station and storage medium

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 30, 2016, the filing date of which is hereby incorporated by reference.

Technical field

The present invention relates to a wireless communication technology, and in particular, to a physical uplink control channel (PUCCH, Physical Uplink Control CHannel) resource allocation method, a base station, and a storage medium.

Background technique

In the Long Term Evolution (LTE) system, the PUCCH is mainly used to carry uplink L1/L2 control information (UCI, Uplink Control Information) to support uplink and downlink data transmission. The UCI may include a scheduling request (SR, Scheduling Request), a positive acknowledgment of a hybrid automatic transmission request or a negative acknowledgment (HARQ ACK/NACK, Hybrid Automatic Repeat request ACKnowledgment/Negative ACKnowledgment), and channel state information (CSI, Channel State Information). Part. The frequency domain resources occupied by the PUCCH may include frequency domain resources occupied by the CSI, frequency domain resources occupied by the SR, and frequency domain resources occupied by the HARQ. The frequency domain resources occupied by the CSI and the SR may be calculated according to the cell user capacity, the CSI, and the SR periodic configuration. Some of the frequency domain resources occupied by the HARQ are semi-statically configured by the base station, and may be referred to as static HARQ resources. A part is determined by an index of a minimum unit of a Physical Downlink Control Channel (PDCCH), that is, a Control Channel Element (CCE), and may be referred to as dynamic HARQ.

The PUCCH has a large resource overhead, and the dynamic HARQ is used in some scenarios. And adding the image symmetry feature of the PUCCH distribution and the randomness characteristic of the HARQ distribution caused by the PDCCH resource search following the hash function, the PUCCH HARQ region bandwidth is segmented into fragments. Therefore, with the use of PUCCH, the number of fragments is increased, thereby reducing the resource utilization rate of the PUCCH.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

Embodiment 1

Referring to FIG. 1 , a method for allocating a PUCCH resource according to an embodiment of the present invention is shown. The method may be applied to a base station side, and the method may include:

S101: Collect identification parameters of the current cell.

In an embodiment, the identification parameter of the current cell may include, but is not limited to, the number of currently connected users of the cell, the number of currently activated users of the cell, the status of the cell scene, and the capacity of the current network configuration of the SR/CSI, and the service is performed within a preset time period in the cell. The number of users and other parameters. In the implementation process, these identification parameters can be obtained from the base station service high level.

S102: According to a preset configuration parameter of the cell PUCCH and an identifier of the current cell, at least one of a cell level parameter of the PUCCH, an SR/CSI resource parameter in the PUCCH, and a static ACK/NACK resource area in the PUCCH according to a preset optimization strategy. Optimize the configuration.

Through the solution shown in FIG. 1 , the optimal configuration can be performed from multiple aspects of the PUCCH, thereby solving the problem of large PUCCH overhead, improving the resource utilization of the PUCCH, and improving the performance of the uplink transmission.

For example, the initial configuration parameter of the PUCCH of the cell, the solution shown in FIG. 1 may further include: initial configuration of the cell level parameter of the PUCCH and the SR/CSI resource parameter before the step S102.

In an embodiment, the initial configuration of the cell-level parameters of the PUCCH may include:

The initial positions of the dynamic ACK/NACK resource regions in the nCS-AN, deltaPUCCH-Shift, and PUCCH are initially configured.

It should be noted that nCS_AN represents PUCCH Format1/1a/1b and PUCCH Format. 2/2a/2b is the number of code channels reserved for PUCCH Format1/1a/1b when one RB is mixed; when this parameter is configured to 0, it indicates that the cell does not support PUCCH Format1/1a/1b and PUCCH Format2/2a/2b. Mixed in one RB, otherwise, indicates that PUCCH Format1/1a/1b is mixed with PUCCH Format 2/2a/2b in one RB. In this embodiment, it can be initially configured to be 0.

It should be noted that deltaPUCCH-Shift represents the inter-code interval of PUCCH Format1/1a/1b. This parameter directly determines the number of users that PUCCH Format1/1a/1b can support on one RB; the smaller the deltaPUCCH-Shif configuration, The resources of the dynamic PUCCH HARQ-ACK area are less. In this embodiment, it can be configured as 3.

It should be noted that the starting position of the dynamic ACK/NACK resource region in the PUCCH may be configured as “a static ACK/NACK resource region in the immediate vicinity of the PUCCH” in this embodiment.

In an embodiment, initial configuration of the SR/CSI resource parameters may include:

For the initial configuration of the cell-level parameters of the PUCCH and the initial configuration of the SR/CSI resource parameters, the number of users that the cell needs to support may be set, which may include:

The number of users that the cell needs to support initially is the sum of the number of users supported by the cell in each cycle; wherein, the number of users supported in a single cycle = frequency domain resources × time domain resources × code domain resources; the frequency domain resources represent on a single subframe The number of occupied RBs, the number of time domain resources indicates the number of uplink subframes in a single cycle, and the number of code domain resources indicates the maximum number of users multiplexed on a single RB.

It can be understood that after the initial configuration by the above preferred solution, the configuration basis for the optimized configuration of the subsequent step S102 can be provided, and the basic PUCCH resource configuration of the runtime is also provided.

For the step S102, the optimal configuration of the cell-level parameters of the PUCCH may include:

The number of currently connected users in the cell in the identification parameter of the current cell does not exceed the pre-configured first door. Set the nCS_AN to a non-zero value for a limited time;

When the number of currently connected users of the cell in the identification parameter of the current cell is greater than the pre-configured first threshold, the nCS_AN is set to zero;

The first threshold value may be set according to actual conditions;

It can be understood that when the number of connected users of the cell is small, PUCCH Format2/2a/2b and PUCCH Format1/1a/1b can be mixed on one RB, thereby reducing PUCCH overhead.

For the step S102, in an embodiment, the optimal configuration of the cell-level parameters of the PUCCH may also include:

When the cell scene state is low speed, set deltaPUCCH-Shift to 1;

When the cell scene state is high speed, deltaPUCCH-Shift is set to 2.

It can be understood that the smaller the deltaPUCCH-Shif configuration, the less resources of the dynamic PUCCH HARQ-ACK region, that is, the range of PUCCH resource distribution is reduced. Under the condition that the TDD subframe ratio is 2, the fixed deltaPUCCH-Shift is 1, and the dynamic PUCCH HARQ-ACK region can be reduced by 20 RBs compared to the deltaPUCCH-Shift of 3.

For the step S102, the optimal configuration of the SR/CSI resource parameters in the PUCCH may include:

The second difference between the SR/CSI live network configuration capacity and the current number of users accessing the cell, or the second difference between the SR/CSI live network configuration capacity and the number of users performing services within the preset time period in the cell. When the first difference threshold is less than the preset, the SR/CSI resource capacity is increased;

The second difference between the SR/CSI live network configuration capacity and the current number of users accessing the cell, or the second difference between the SR/CSI live network configuration capacity and the number of users performing services within the preset time period in the cell. When the second difference threshold is greater than the preset, the SR/CSI resource capacity is reduced;

The second difference between the current network configuration capacity of the SR/CSI and the current number of access users or the number of users configured to perform services within the preset time period of the SR/CSI When the difference is between the preset first difference threshold and the second difference threshold, the existing SR/CSI resources are maintained unchanged.

It should be noted that the setting of the first difference threshold and the second difference threshold needs to consider the number of access users of the base station in a certain period of time, and the first difference threshold is smaller than the second difference threshold.

In the implementation process of the foregoing preferred solution, as shown in FIG. 2, the method may include:

S201: The second difference between the current network configuration capacity of the SR/CSI and the current number of users in the cell, or the second configured capacity of the SR/CSI network and the number of users performing services in the preset time period in the cell. The difference is compared with a preset first difference threshold; when the first difference or the second difference is smaller than the first difference threshold, step S202 is performed; when the first difference or the second difference is greater than the first difference When the value is threshold, step S203 is performed;

S202: Increase the SR/CSI resource capacity.

S203: Compare the first difference or the second difference with the second difference threshold; when the first difference or the second difference is smaller than the second difference threshold, perform step S204; when the first difference or the first When the difference is greater than the first difference threshold, step S205 is performed;

S204: Maintain the existing SR/CSI resources unchanged;

S205: Reduce the SR/CSI resource capacity.

In an embodiment, increasing the SR/CSI resource capacity may include: increasing frequency domain resources and/or increasing an SR/CSI period of the cell live network configuration.

In the implementation process, the added frequency domain resources can support only one SR/CSI period or support multiple SR/CSI periods, and meet the requirements of the number of cell users and service requirements. When multiple SR/CSI periods are supported, The SR/CSI resources of the cell may be allocated by means of code division or time division in multiple periods; the SR/CSI period of the live network configuration of the cell may be increased, and the period of the SR/CSI resources not allocated to the UE may be increased until the time is satisfied. Capacity requirements of the existing network of the community. If the subsequent SR/CSI period is increased, the SR/CSI period of the online user can be increased to obtain more SR/CSI resources. If the frequency domain resources are added and the SR/CSI period of the live network configuration is increased, the frequency domain can be prioritized. Expansion The secondary period is enlarged, or the priority period is lengthened, and the frequency domain is expanded.

In an embodiment, reducing the SR/CSI resource capacity may include reducing the number of SR/CSI frequency domain resources and/or reducing the SR/CSI period.

In the implementation process, the process of reducing the capacity of the SR/CSI resource is similar to the process of increasing the capacity of the SR/CSI resource, which is not described in this embodiment.

It can be understood that the number of resources of the PUCCH CSI/SR is adaptively adjusted according to the number of users and the current network configuration capacity of the SR/CSI in the foregoing manner, so that the PUCCH CSI/SR resources are fully utilized, and when the user is reduced, the PUCCH resource overhead is reduced.

For the step S102, the optimal configuration of the static ACK/NACK resource region in the PUCCH may include:

When a cell needs to configure a downlink SPS scheduling ACK/NACK feedback resource or a CA Channel Selection PUCCH Format 1b resource, the dynamic ACK/NACK resource region in the PUCCH is from a code channel resource corresponding to the lowest frequency, according to a predetermined code interval. The PUCCH code channel resource is allocated as the downlink SPS scheduling ACK/NACK feedback resource or the CA Channel Selection PUCCH Format 1b resource; wherein the inter-code interval is determined by the configuration value of deltaPUCCH-Shift or is a preset fixed value;

In the PDCCH resource allocation, if the dynamic ACK/NACK resource in the corresponding currently allocated PUCCH collides with the downlink SPS scheduling of the high priority scheduling at the current time and/or the static ACK/NACK resource of the CA secondary carrier scheduling, the new one is searched. The PDCCH resource location is used to ensure that the dynamic ACK/NACK resource corresponding to the new PDCCH resource location is not used.

It can be understood that, for the planning of the PUCCH static ACK/NACK resource region, a fixed resource may be reserved for the static ACK/NACK resource region in the PUCCH resource region according to the resource planning mode of the SR, but the corresponding attribute does not exist in the cell. When the UE is used, the uplink resource may be wasted. In order to reduce the waste of the resource, especially in the TDD, the static ACK/NACK resource and the dynamic ACK/NACK resource may be used to occupy the resource.

The PUCCH resource allocation method provided in this embodiment can be optimally configured from multiple aspects of the PUCCH, thereby solving the problem of large PUCCH overhead, improving the resource utilization of the PUCCH, and improving the performance of the uplink transmission.
