Description

Resource allocation method and device

Technical Field

The present invention relates to a resource allocation technology in the field of communications, and in particular, to a resource allocation method and apparatus.

Background

With the development of long term evolution (LTE, long Term Evolution), the rate requirements of users are increased, carrier aggregation (CA, carrier Aggregation) is used as the main technology of LTE, which occupies more CA spectrum or bandwidth resources, while the protocol standard organization is already developing a new frequency range, in general, CA spectrum or bandwidth resources are quite limited, in the information age of big data, it is more and more important to improve the spectrum utilization, reasonably allocate CA spectrum or bandwidth resources, and reduce the waste of frequency resources.

According to the current development of LTE technology, the rate is faster and faster, and the current downlink 3-carrier CA technology is already used, and the downlink 5-carrier CA technology is developed later, and the multiple input multiple output (MIMO, multiple Input Multiple Output) technology is superimposed on the current downlink 3-carrier CA technology. In order to increase the rate, the multi-antenna and multi-carrier technology is always added to the existing scheme, while the CA spectrum or bandwidth resources are limited and the demand for bandwidth is increasing, whether the prior art or the development architecture of the subsequent technology. How to reasonably allocate CA frequency spectrum or bandwidth resources and improve the use efficiency becomes a problem to be solved urgently.

In the prior art, discontinuous reception (DRX, discontinuous Reception) indicates that a User Equipment (UE) listens to a physical channel of a base station at a certain periodic interval, and the DRX is divided into two types: IDLE (IDLE) DRX, that is, DRX when the UE is in IDLE state, is mainly listening to the paging channel and the broadcast channel, since there is no radio resource control (RRC, radio Resource Control) connection (RRC-CONNECTED) and the dedicated CA spectrum or bandwidth resources of the user already in IDLE state; when the UE is to listen to the user data channel, it must enter the connected state from the IDLE state. The other ACTIVE DRX, i.e. the DRX in which the UE is in the RRC-CONNECTED state, can save the terminal power without having to enter the terminal into the rrc_idle mode to achieve this, for example, some non-real-time applications, such as web browsing, instant messaging, etc., always exist for a period of time, the terminal does not need to monitor the downlink data and related processing, so DRX can be applied to such a case, and in addition, since there is still an RRC connection in this state, the speed of the UE to go to the supporting state is very fast. The existing DRX is mainly performed to reduce the power consumption of the UE, and the DRX parameters of the LTE are selected by the RRC layer according to the quality of service (QoS, quality of Service), delay sensitivity (delay sensitive) and other characteristics of different services. Since the uplink transmission of LTE is completely dependent on the scheduling of the base station, the UE is not expected to report parameters such as channel quality indication (CQI, channel Quality Indicator) during the DRX cycle in rrc_connected state. Thus, uplink CA spectrum or bandwidth resources of LTE are saved. DRX in LTE is selected by taking service characteristics into consideration by RRC in RRC_connected state, and the method can optimize CA frequency spectrum or bandwidth resource space of LTE in actual application.

In the present LTE CA technology, the primary and secondary cells use DRX with the same period, which is still mainly aimed at monitoring the physical channel, reducing UE power consumption and optimizing CA spectrum or bandwidth resources, and not using different states of DRX, or adding a reference signal in the LTE slot to binary encode the state of DRX, and using this encoding to implement allocation of some CA spectrum or bandwidth resources.

Detailed Description

So that the manner in which the features and objects of the present invention can be understood in more detail, a more particular description of the invention, briefly summarized above, may be had by reference to the appended drawings, which are not necessarily limited to the embodiments described.

The embodiment of the invention provides a resource allocation method, which is applied to a terminal side, as shown in fig. 1, and in a preferred embodiment of the invention, the resource allocation method mainly comprises the following steps:

step 101: the terminal detects a state of Discontinuous Reception (DRX).

The DRX state is mainly divided into two main types, one is an IDLE DRX state and the other is an ACTIVE DRX state.

Specifically, when the DRX state is in the IDLE DRX state, it indicates that the terminal is in a standby state, and at this time, the base station is not required to allocate resources for the terminal.

Specifically, when the DRX state is in the ACTIVE DRX state, it indicates that the terminal has entered the connected state; in the ACTIVE DRX state, DRX may not be detected, which indicates that the terminal is in a use state with a large data requirement at this time, and the base station needs to allocate the maximum primary and secondary cells and bandwidth for the terminal; the DRX may be detected, which indicates that the terminal is in a non-real-time application usage state at this time, and when the terminal is in the non-real-time application usage state, if the detected DRX belongs to Long DRX, which indicates that the terminal is in a connected state and needs to use a small amount of data traffic, the base station only needs to allocate the minimum primary and secondary cells and bandwidth to the terminal; if the detected DRX belongs to Short DRX, the terminal is in a connected state and needs to use moderate data traffic, and the base station only needs to allocate moderate primary and secondary cells and bandwidth for the terminal.

The "maximum", "minimum", and "moderate" resources are relative to the range of resources that the current base station can allocate to the terminal and the resources that the terminal can support.

For example, the largest resource may refer to 20M traffic, and the smallest resource may refer to 1.4M, 3M, 5M (the bandwidths supported by the respective frequency bands are not uniform) traffic; moderate resources refer to 10M or 15M traffic.

Step 102: and coding the DRX state detection result according to a preset strategy.

Preferably, the coding the DRX state according to a preset policy includes:

when the state of the DRX is detected to be in an IDLE DRX state, setting the first bit code to 0, wherein when the first bit code is 0, the terminal is in a standby state; at this time, detection of the second, third and fourth bits is not started any more; reporting the detection result of the first bit to the base station directly;

when the DRX state is detected to be in an ACTIVE DRX state, setting a first bit code to be 1, wherein when the first bit code is 1, the terminal is indicated to enter a connection state; at this time, starting a second bit detection, if the detection result of whether DRX is detected in the ACTIVE DRX state is that DRX is not detected, setting a second bit code to 0, wherein when the second bit code is 0, indicating that the terminal is in a use state with big data requirement, reporting the detection result of the second bit to the base station, and then starting a fourth bit detection; if the detection result of whether DRX exists in the ACTIVE DRX state is that DRX is detected, setting a second bit code to be 1, wherein when the second bit code is 1, the terminal is in a non-real-time application use state, starting third bit detection, and if the detection result of whether the DRX belongs to long period DRX or short period DRX belongs to long period DRX, setting the third bit code to be 0, wherein when the third bit code is 0, the terminal is in a connection state and needs to use a small amount of data flow, reporting the detection result of the third bit to a base station, and starting fourth bit detection; if the detection result of whether the DRX belongs to the long cycle DRX or the short cycle DRX belongs to the short cycle DRX, setting a third bit code to be 1, wherein when the third bit code is 1, the terminal is in a connection state and needs to use moderate data flow, reporting the detection result of the third bit to the base station at the moment, and then starting fourth bit detection;

If the terminal is detected to finish using the CA frequency spectrum or bandwidth resource, setting the fourth bit code to be 1, and reporting the detection result of the fourth bit to the base station; if the terminal is detected that the use of the CA frequency spectrum or the bandwidth resource is not finished, the fourth bit code is set to 0, and the detection result of the fourth bit is reported to the base station.

Further, the method further comprises:

for the four-bit binary encoding of the current set of RRSs,

if the fourth bit code is 1, the terminal clears the RRS information, and then resumes the first group of code detection;

Here, the fourth bit corresponds to a check code.

Step 103: a Reception Reference Signal (RRS) is generated according to the encoding result.

Preferably, the RRS is a signal consisting of a plurality of sets of four-bit binary codes; wherein, for each set of four-bit binary codes,

Optionally, the RRS is located in an LTE slot,

for the frame structure of time division duplex TDD, RRS is added after the OFDM symbols in the downlink pilot time slot DwPTS in the special time slot.

That is, the data usage state of the terminal, such as standby, connected or intermittent surfing, is distinguished by encoding the state of the DRX; in this way, the base station can preferentially allocate more LTE carriers or bandwidths to users with continuous downloading of large data.

Fig. 2 shows a schematic diagram of the position and coding of RRS in an FDD frame, for the frame structure of FDD: a radio frame of length 10ms is made up of 10 subframes of length 1ms, each subframe being made up of two slots of length 0.5 ms. Whereas DRX is mainly listening to PDCCH, in FDD subframes #1 and #6 are used for PDCCH transmission, so one RRS (202) is added after OFDM symbols in slot #1 and slot #6 (201); 203 are all possible coding combinations of FDD RRS.

Fig. 3 shows a schematic diagram of the positions and coding of RRS in a TDD frame, for the frame structure of TDD: a radio frame of length 10ms is composed of 2 fields of length 5ms, each field being composed of 5 subframes of length 1 ms. Normal subframe: consists of two slots of length 0.5ms (subframes 0-9). Special subframes: is composed of DwPTS, guard interval (GP) and uplink pilot time slot (UpPTS, uplink Pilot Time Slot). Supporting 5ms and 10ms dl→ul switch point periods. Whereas DRX is mainly listening to PDCCH, in TDD, special slots are used for transmission of PDCCH, so one RRS (302) is added after OFDM symbols in special slot DwPTS (301), 303 is all possible coding combinations of TDD RRS.

Step 104: and reporting the RRS to a base station, so that the base station performs resource allocation according to the RRS.

Thus, the base station distinguishes the size and the quantity of the data flow required by the UE according to the reported RRS coding result, so that CA spectrum or bandwidth allocation is carried out, and the maximum utilization of the existing CA spectrum or bandwidth resource is achieved.

The embodiment of the invention also discloses a computer storage medium, and the computer storage medium stores a computer program, and the computer program is used for executing the resource allocation method shown in fig. 1 in the embodiment of the invention.
