Description

Physical uplink control channel PUCCH resource allocation method and base station

Technical Field

The present invention relates to wireless communication technologies, and in particular, to a Physical Uplink Control CHannel (PUCCH) resource allocation method and a base station.

Background

In a Long Term Evolution (LTE) system, a PUCCH is mainly used to carry Uplink L1/L2 Control Information (UCI) to support Uplink and downlink data transmission. Specifically, the UCI may include Scheduling Request (SR), Hybrid Automatic Repeat Request (HARQ ACK/NACK) acknowledgement/Negative acknowledgement (CSI) and Channel State Information (CSI). The frequency domain resources occupied by the PUCCH may include frequency domain resources occupied by CSI, frequency domain resources occupied by SR, and frequency domain resources occupied by HARQ. The frequency domain resources occupied by the CSI and the SR can be obtained by calculation according to the user capacity of the cell and the periodic configuration of the CSI and the SR; in the frequency domain resources occupied by HARQ, a part of the frequency domain resources is configured semi-statically by the base station, and may be referred to as static HARQ resources, and a part of the frequency domain resources is determined by a minimum unit of a Physical Downlink Control Channel (PDCCH), that is, an index of a Control Channel Element (CCE), and may be referred to as dynamic HARQ.

Due to the particularity of the PUCCH, the Resource overhead of the PUCCH is usually large, and dynamic HARQ is used more in some scenarios, and may occupy 30 Resource Blocks (RBs) at maximum, that is, 3/10 of the total bandwidth, and in addition to the mirror symmetry characteristic 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 may be divided into fragments. Therefore, as the PUCCH is used, more fragments are generated, thereby reducing the resource utilization rate of the PUCCH.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

Referring to fig. 1, it shows a PUCCH resource allocation method provided in an embodiment of the present invention, which may be applied to a base station side, and the method may include:

s101: collecting identification parameters of a current cell;

specifically, the identification parameters of the current cell may include, but are not limited to: the number of current connected users of the cell, the number of current activated users of the cell, the current scene state of the cell, the current network configuration capacity of the SR/CSI, the number of users performing services in a preset time period in the cell and other parameters. In a specific implementation process, the identification parameters may be obtained from a higher service layer of the base station.

S102: and optimally configuring 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 region in the PUCCH according to a preset optimization strategy based on the initial configuration parameter of the cell PUCCH and the identification parameter of the current cell.

Through the scheme shown in fig. 1, optimal configuration can be performed from multiple aspects of the PUCCH, so that the problem of high PUCCH overhead is solved, the resource utilization rate of the PUCCH is improved, and the performance of uplink transmission is improved.

For example, for the initial configuration parameters of the cell PUCCH, the scheme shown in fig. 1 may further include, before step S102: and initially configuring the cell level parameters of the PUCCH and the SR/CSI resource parameters.

Optionally, the initial configuration of the cell level parameter of the PUCCH may include:

and initially configuring the starting position of the dynamic ACK/NACK resource region in nCS-AN, deltaPUCCH-Shift and PUCCH.

Note that nCS _ AN represents the number of code channels reserved for PUCCH Format1/1a/1b when PUCCH Format1/1a/1b and PUCCH Format2/2a/2b are mixed in one RB; when the parameter is configured to be 0, the cell does not support the mixing of the PUCCH Format1/1a/1b and the PUCCH Format2/2a/2b in one RB, otherwise, the cell supports the mixing of the PUCCH Format1/1a/1b and the PUCCH Format2/2a/2b in one RB. In this embodiment, the configuration may be initially 0.

It should be noted that deltaPUCCH-Shift represents the inter-code space of PUCCH Format1/1a/1b, and the parameter directly determines the number of users that the PUCCH Format1/1a/1b can support on one RB; the smaller the deltaPUCCH-Shif configuration is, the less resources of the dynamic PUCCH HARQ-ACK region are. In the present embodiment, 3 may be configured.

It should be further noted that the starting position of the dynamic ACK/NACK resource region in the PUCCH may be configured as "static ACK/NACK resource region next to PUCCH" in this embodiment "

Optionally, the initial configuration of the SR/CSI resource parameter may include:

For the initial configuration of the cell level parameter of the PUCCH and the SR/CSI resource parameter, the number of users that need to be initially supported by the cell may also be set, which specifically includes:

the number of users to be supported initially in the cell is the sum of the number of users supported in each period of the cell; the number of users supported in a single period is equal to frequency domain resources multiplied by time domain resources multiplied by code domain resources; specifically, the frequency domain resource represents the number of RBs occupied by a single subframe, the time domain resource represents the number of uplink subframes in a single period, and the number of code domain resources represents the maximum number of multiplexed users on a single RB.

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

For step S102, preferably, the optimally configuring the cell level parameters of the PUCCH includes:

when the number of the current cell connection users in the identification parameter of the current cell does not exceed a pre-configured first threshold, setting nCS _ AN as a non-zero value;

and when the number of the current cell connection users in the identification parameter of the current cell is larger than a pre-configured first threshold, setting nCS _ AN to be zero.

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

For step S102, preferably, the performing optimized configuration on the cell level parameter of the PUCCH may also include:

when the cell scene state is low speed, setting deltaPUCCH-Shift as 1;

and when the cell scene state is high speed, setting deltaPUCCH-Shift 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 compared with the deltaPUCCH-Shift being 3, the dynamic PUCCH HARQ-ACK area can be reduced by 20 RBs.

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

when a first difference value between the SR/CSI current network configuration capacity and the number of the current access users of the cell or a second difference value between the SR/CSI current network configuration capacity and the number of the users performing services in a preset time period in the cell is smaller than a preset first difference value threshold, increasing the SR/CSI resource capacity;

when a first difference value between the SR/CSI current network configuration capacity and the number of the current access users of the cell or a second difference value between the SR/CSI current network configuration capacity and the number of the users performing services in a preset time period in the cell is larger than a preset second difference value threshold, the SR/CSI resource capacity is reduced;

and when a first difference value between the SR/CSI current network configuration capacity and the current access user number or a second difference value between the SR/CSI current network configuration capacity and the user number performing services in a preset time period in the cell is between a preset first difference value threshold and a preset second difference value threshold, keeping the current SR/CSI resources 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 time, and the first difference threshold is smaller than the second difference threshold.

In the implementation process of the above preferred embodiment, as shown in fig. 2, the method may include:

s201: comparing a first difference value between the SR/CSI current network configuration capacity and the number of the current access users of the cell or a second difference value between the SR/CSI current network configuration capacity and the number of the users performing services within a preset time period in the cell with a preset first difference threshold; when the first difference or the second difference is smaller than the first difference threshold, executing step S202; when the first difference or the second difference is greater than the first difference threshold, executing step S203;

s202: increasing the SR/CSI resource capacity;

s203: comparing the first difference or the second difference with a second difference threshold; when the first difference or the second difference is smaller than the second difference threshold, executing step S204; when the first difference or the second difference is greater than the first difference threshold, performing step S205;

s204: maintaining the existing SR/CSI resources unchanged;

s205: reduce the SR/CSI resource capacity.

Specifically, increasing SR/CSI resource capacity may include: and increasing frequency domain resources and/or increasing the SR/CSI period of the current network configuration of the cell.

In a specific implementation process, the added frequency domain resources may only support one SR/CSI cycle or support multiple SR/CSI cycles, and when multiple SR/CSI cycles are supported, the SR/CSI resources of a cell may be allocated by means of code division or time division during multiple cycles on the principle that the number of users of the cell and service requirements are met; and increasing the SR/CSI period configured by the current network of the cell, and increasing the period of the SR/CSI resource which is not allocated to the UE until the capacity requirement of the current network of the cell is met. If the SR/CSI period is not satisfied, more SR/CSI resources can be obtained by increasing the SR/CSI period of the reconfigured online user; the frequency domain resources are increased, the SR/CSI period configured by the current cell network is increased, frequency domain expansion can be performed firstly, the period is enlarged, or the period is lengthened firstly, and the frequency domain expansion is performed secondly.

Specifically, reducing the SR/CSI resource capacity may include: and reducing the number of SR/CSI frequency domain resources and/or reducing the SR/CSI period.

In the specific implementation process, the process of reducing the SR/CSI resource capacity is similar to the specific implementation process of increasing the SR/CSI resource capacity, and details are not repeated in this embodiment.

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

For step S102, preferably, the optimally configuring the static ACK/NACK resource region in the PUCCH may include:

when a cell has a resource which needs to be configured with downlink Semi-persistent Scheduling (SPS) to schedule ACK/NACK feedback resources or Carrier Aggregation (CA) Channel Selection (Channel Selection) PUCCH Format1b, allocating PUCCH code Channel resources as downlink SPS Scheduling ACK/NACK feedback resources or CA Channel Selection PUCCH Format1b resources at a preset inter-code interval from code Channel resources corresponding to the lowest frequency in a dynamic ACK/NACK resource region in the PUCCH; the inter-code interval is determined by a configuration value of deltaPUCCH-Shift or is a preset fixed value;

when the PDCCH resources are allocated, if the dynamic ACK/NACK resources in the corresponding currently allocated PUCCH collide with the static ACK/NACK resources scheduled by the downlink SPS scheduling and/or CA auxiliary carrier scheduling of the current time high priority, a new PDCCH resource position is searched, so that the dynamic ACK/NACK resources corresponding to the new PDCCH resource position are ensured to be unused.

It can be understood that, for the planning of the PUCCH static ACK/NACK resource region, according to the resource planning mode of SR, a fixed resource may be reserved in the PUCCH resource region for use by the static ACK/NACK resource region, but when there is no UE with corresponding attribute in the cell, uplink resource waste may be caused, and in order to reduce the resource waste, especially in TDD, a solution may be adopted in which the static ACK/NACK resource and the dynamic ACK/NACK resource occupy resources in a mixed manner.

The embodiment provides a PUCCH resource allocation method, which can perform optimal configuration from multiple aspects of a PUCCH, thereby solving the problem of high PUCCH overhead, improving the resource utilization rate of the PUCCH, and improving the performance of uplink transmission.
