Description

Resource allocation method and device

Technical Field

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

Background

The service types mainly considered in the field of fifth Generation mobile communication technology (5G) include: ultra-large mobile bandwidth (eMBB), massive-type communications (mtc), ultra-reliable low latency communications (URLLC), and so on. The overall demand for 5G stems from the demands of various business and usage scenarios. The entire 5G radio access network operates over a wide frequency band to process and transmit various services, such as frequencies below 6GH may be better suited to support mtc services, and frequencies above the 6th Generation mobile communication technology (abbreviated as 6G) may be better suited to provide high capacity requirements in eMBB applications. Due to the wide range of bandwidth and the diversity of service types, the whole 5G air interface has a plurality of 5G air interface variants (AIVS for short), including the existing wireless further enhancement of the current long term evolution enhancement (LTE-a) and the new AIVS introduced in 5G. The AIVS may be selected based on different frequency bands, cell types, or traffic types. For possible designs of two AIVs below the 3G frequency and above 60G, the two AIVs differ mainly in terms of physics, frame structure, importance of beamforming, and control signaling related processing.

At present, the physical layer of the system has agreed that User equipments (User Equipment, abbreviated as UE) with different bandwidths can access the same New radio access technology (New RAT, abbreviated as NR) carrier, and the bandwidths of the terminal and the system can be freely configured, and the channel bandwidth of the terminal and the channel bandwidth of the network side can be flexibly configured.

In addition, there are two methods currently implemented in the industry for coverage enhancement: one is to increase the coverage problem of the paging area by means of beamforming; another approach is to achieve enhanced coverage by multiple paging.

The resource configuration related to paging mainly comprises: to determine the periodic Discontinuous Reception (DRX) of the paging time when the UE monitors the downlink paging message, and the bandwidth for sending the paging message. For a terminal in an IDLE state in a basic integrated development environment, relevant paging parameter configuration of a Long Term Evolution (Long Term Evolution, LTE) system may be reused, including: paging cycle DRX, paging density NB. The physical layer of the current system has consensus, the same NR carrier can be accessed to UE with different bandwidths, the bandwidths of the terminal and the system can be freely configured, and the channel bandwidth of the terminal and the channel bandwidth of the network side can be flexibly configured. At present, there is still a gap in the resource configuration of the Paging message for Paging the NR UE. The resource allocation and paging process suitable for the paging of the UE cannot be determined, so that the paging resource suitable for the UE cannot be allocated, resource waste is caused, and the paging reliability is reduced.

In view of the above technical problems, no effective solution has been proposed in the related art.

Preferably, if the UE reporting capability is high and is limited to narrowband bandwidth transmission, the UE is subjected to the size of a narrowband carrier group configured by the network side; paging transmission repetition times; the network side and the UE side determine the sub-carriers for sending the paging message through a certain algorithm, for example, identify the sub-carrier group by the UE.

Preferably, based on the paging density and the paging cycle, the network side and the UE side determine the sending time of the paging message through a certain algorithm, for example, through the UE identity mode paging cycle and the minimum value of the paging density.

Preferably, the access parameters include: a manner of random access procedure; the AS layer triggers a paging response process; NAS triggers the paging response flow; AIVs-related parameters; further, the random access procedure includes two modes: a two-step random access process; four steps of random access process; further AIVs related parameters: including the frequency; numerology; a period of SS burst set; the method of SS block scanning, wherein the state of the UE can be idle state, fully connected state, or inactive state. The reporting of the UE capability informs the RAN to measure through an uplink air interface message, such as a UE capability information message, and the RAN side reports the UE capability information to NG through a Next Generation operator (NGC for short).

Preferably, when the paging keep-alive timer expires, the user may initiate a location update message to the RAN side or the NG side to notify the RAN side or the NG side that the user is reachable.

Step 704: and the eNB sends the resource configuration related to the UE characteristic paging to the UE through a downlink dedicated message.

Specific implementation 5:

fig. 8 is a flowchart (v) of resource allocation in the embodiment of the present invention, and as shown in fig. 8, the eNB retains capability information of the UE and/or UE mobility information and/or measurement report information of the UE, and the UE is in a connected-state inactive state. The method comprises the following specific steps:

and the eNB carries out paging related resource allocation based on the capability information of the UE and/or the UE movement information and/or the measurement report information of the UE. When the NR UE is in an inactive state of the RRC, the mobility of the inactive UE in the RAN-based notification area configured on the network side does not send any uplink signal any more, and at this time, the eNB cannot implement real-time measurement and/or feedback reception based on the mobility of the inactive UE, and thus cannot acquire sufficient characteristics of the paged inactive UE, and finally the eNB cannot provide a Paging procedure adapted to the characteristics of the inactive UE. Therefore, it is proposed that the eNB simultaneously saves the historical measurement results or feedback results of the UE's movement in the RAN-based notification area to determine whether to operate the re-enhancement mode; the eNB will usually store the context of the inactive UE in RRC inactive state, so it is suggested to save the uplink and downlink transmission capability of the UE and whether to support enhanced coverage capability and whether to be limited by the narrow-band transmission bandwidth in the context of the UE, determine the DRX duration by the UE service characteristics, and the eNB provides the parameter configuration of the Paging process adapted to the NR UE characteristics: paging transmission bandwidth, narrowband transmission bandwidth group size, paging transmission repetition number, DRX and access parameters.

Preferably, the transmission bandwidth of the UE is smaller than the transmission bandwidth of the system, the system bandwidth may be further subdivided into multiple narrow bandwidths, and different UEs may be paged on different narrow bandwidths.

Preferably, the transmission bandwidth of the UE is larger than the transmission bandwidth of the system, and the system may subdivide the UE bandwidth into different narrow bandwidths and then page the UE multiple times on the different narrow bandwidths.

The eNB sends the UE the resource configuration related to the UE characteristic paging. The downlink common message can be sent to the UE, or the system message can be sent to the UE, or the request message is recovered to make the UE switch to the connected state, and then the resource configuration related to UE paging is sent to the UE.

Specific example 6:

as shown in fig. 8, the eNB keeps the capability information of the UE and/or the UE mobility information and/or the measurement report information of the UE, the UE is in a connected inactive state, and the UE supports enhanced coverage. The method comprises the following steps:

step 802: the eNB receives downlink data or control signaling.

Step 804: a paging timer is started.

Step 806: paging is performed using non-enhanced coverage.

Step 808: the paging timer times out.

Step 810: the enhanced coverage is initiated for paging.
