It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.
Referring to fig. 1, an architecture diagram of a wireless communication system is provided in an embodiment of the present invention. The wireless communication system may include: in practical applications, the network device 10 and the terminal 11 connected to the network device 10 may be connected wirelessly, and for convenience, the connection relationship between the devices is shown intuitively, and is illustrated by a solid line in fig. 1.
It should be noted that the communication system may include a plurality of terminals 11, and the network device 10 may communicate (transmit signaling or transmit data) with the plurality of terminals 11.
The network device 10 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network device 10 in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), or a cell) and other devices.
The terminal 11 provided in the embodiment of the present invention may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or the like.
Referring to fig. 2, an embodiment of the present invention provides a dynamic resource allocation method, where an execution subject of the method may be a network device, and the network device may be a common mode device, such as a 4G/5G common mode device, but is not limited thereto. The method comprises the following specific steps:
step 201: activating at least two BWPs of a terminal, wherein at least partial frequency band bandwidths configured by different BWPs are different; or configuring at least two sets of parameters for a BWP of the terminal, where the parameters indicate different resource frequency bands or overlapped resource frequency bands.
In the embodiment of the present invention, the BWP is a Common (Common) BWP or a Dedicated (Dedicated) BWP.
In an embodiment of the present invention, the at least two BWPs comprise: the bandwidth of the frequency band configured by the first BWP is different from that of the second BWP.
Further, the first BWP overlaps with a frequency band bandwidth of a fourth generation mobile communication technology network, a third generation mobile communication technology network, a second generation mobile communication technology network, a first generation mobile communication technology network, satellite communication, broadcast communication, an unlicensed frequency band, or a millimeter wave frequency band. The band bandwidth of the second BWP and the first BWP configuration may be different, for example: when the first BWP overlaps with the band bandwidth of 4G, the second BWP may be configured within a bandwidth other than the band bandwidth of the fourth generation mobile communication technology network, for example, the second BWP may be configured within the band bandwidth of the fifth generation mobile communication technology network.
If the first BWP overlaps with a fourth generation mobile communication technology network, a third generation mobile communication technology network, a second generation mobile communication technology network, a first generation mobile communication technology network, satellite communication, broadcast communication, an unlicensed frequency band, or a frequency band bandwidth of a millimeter wave frequency band, the first BWP performs forward compatibility and/or rate matching with the fourth generation mobile communication technology network, the third generation mobile communication technology network, the second generation mobile communication technology network, the first generation mobile communication technology network, satellite communication, broadcast communication, the unlicensed frequency band, or the millimeter wave frequency band.
For example: the network device simultaneously activates a first BWP and a second BWP for the terminal, where the first BWP overlaps with a Long Term Evolution (LTE) frequency band bandwidth and is forward compatible and/or rate matched with LTE, that is, the subcarrier spacing may be set to 15KHz, and NR (New radio, NR) data is not transmitted on resource blocks of existing reference signals (e.g., CRS) and control channels in LTE; the second BWP is configured in the NR frequency band bandwidth, for example, the subcarrier spacing may be configured to be 30KHz/60KHz/120KHz, and other parameters are configured according to the actual usage of the NR frequency band, where the parameters may include: bandwidth size, resource starting position, resource size, subcarrier spacing, cyclic prefix format, control channel format, traffic channel format, antenna port mapping scheme or modulation and demodulation mode, etc.
In some embodiments, when the first BWP is forward compatible and/or rate matched with the fourth generation mobile communication technology network, the time domain of the first BWP does not schedule symbols corresponding to the reference signal of the fourth generation mobile communication technology network, and the frequency domain of the first BWP occupies the entire frequency bandwidth of the fourth generation mobile communication technology network, so that NR data may not be transmitted on the entire column of symbols where LTE-already-existing reference signals (e.g., CRS) are located, thereby preventing interference with reference signal measurement in the LTE neighbor cell.
In an embodiment of the invention, the parameters comprise one or more of: bandwidth size, resource starting position, resource size, subcarrier spacing, cyclic prefix format, control channel format, traffic channel format, antenna port mapping scheme and modulation and demodulation mode.
In the embodiment of the present invention, each set of parameters may indicate different resource frequency bands or overlapped resource frequency bands; it will be appreciated that different parameters may be configured for different resource bands of the same BWP or different BWPs.
In order to facilitate understanding of the dynamic resource allocation method according to the embodiment of the present invention, several preferred embodiments thereof are described below. The present invention is not limited to the following two embodiments.
The first implementation mode comprises the following steps:
it is assumed that the network device activates two BWPs for the terminal at the same time, and the two BWPs include: the first BWP and the second BWP, the frequency band occupied by NR is 2515MHz-2575MHz, and LTE occupies 2575MHz-2615 MHz.
The bandwidth of the first BWP frequency band may be configured to 2575MHz-2615MHz, so that the bandwidth of the first BWP frequency band overlaps with the bandwidth of the LTE frequency band, and specifically, a scheme for indicating forward compatibility and rate matching with the LTE may be performed through a parameter RateMatchPattern, for example, the subcarrier spacing may be configured to be 15KHz, and an NR control channel, a traffic channel, and/or a Reference Signal and the like are not transmitted on an existing Reference Signal (e.g., a Cell Reference Signal (CRS)) and a control channel of the LTE; the band bandwidth of the second BWP may be configured to be 2515MHz-2575MHz such that the second BWP is within the current NR band bandwidth and the second BWP does not need to be forward compatible. The subcarrier spacing can be configured to be 30KHz/60KHz/120KHz, and other parameters can be configured according to the actual use condition of the NR bandwidth, including: bandwidth size, resource starting position, resource size, subcarrier spacing, cyclic prefix format, control channel format, traffic channel format, antenna port mapping scheme and/or modulation and demodulation mode, etc.
The second embodiment:
assuming that the bandwidth of the frequency band occupied by the NR is 2515MHz-2575MHz, the bandwidth of the frequency band occupied by the LTE is 2575MHz-2615MHz, the total bandwidth of the third BWP is 100M, and the third BWP occupies the frequency band 2515MHz-2615MHz and has 275 RBs in total. Now 2 sets of parameters are configured for the third BWP, where:
1) configuration 0 indicates that 220 RBs can be used in the first 80M bandwidth, an uplink and Downlink 30K subcarrier interval and a common format cyclic prefix are adopted, the aggregation level of a Downlink Physical Downlink Control Channel (PDCCH) is 16, the Modulation mode of a Physical Downlink Shared Channel (PDSCH) is maximum 256 Quadrature Amplitude Modulation (QAM), and the antenna port mapping scheme is 8 ports; the uplink PUCCH is configured into a format 0(format0), and the PUSCH modulation mode is maximum 256QAM and the like;
2) configuration 1 indicates that 55 RBs can be used in the rear 20M bandwidth, the uplink and downlink 15K subcarrier intervals and the common format cyclic prefix are adopted, the downlink PDCCH aggregation level is 8, the PDSCH modulation mode is maximum 64QAM, and the antenna port mapping scheme is 2 ports; the uplink PUCCH is configured to be format0, and the PUSCH modulation mode is maximum 64 QAM.
In the embodiment of the present invention, the network device may activate at least two BWPs for the same terminal, where at least part of the frequency band bandwidths configured for different BWPs are different, or configure at least two sets of parameters for one BWP of the terminal, so that the terminal may perform services on different frequency band bandwidths of different BWPs respectively or simultaneously, and may improve resource utilization.
For example: when the service is carried out on the 4G frequency band, the terminal can keep the connection with a 5G core network, transmission and network management, and the terminal can adopt a 5G frame structure and subcarrier intervals to receive and transmit 5G messages without influencing the existing performance of 4G. Namely, the method of the embodiment of the invention can respectively or simultaneously perform services on the frequency band bandwidths dynamically configured by the 4G and the 5G when the utilization rate of the 4G resources is low, can improve the service experience of the 5G while not influencing the use of the 4G, and can also improve the utilization rate of the 4G resources.

Further, the first BWP overlaps with a frequency band bandwidth of a fourth generation mobile communication technology network, a third generation mobile communication technology network, a second generation mobile communication technology network, a first generation mobile communication technology network, satellite communication, broadcast communication, an unlicensed frequency band, or a millimeter wave frequency band. The band bandwidth of the second BWP and the first BWP configuration may be different, for example: when the first BWP overlaps with the band bandwidth of 4G, the second BWP may be configured within a bandwidth other than the band bandwidth of the fourth generation mobile communication technology network, for example, the second BWP may be configured within the band bandwidth of the fifth generation mobile communication technology network.
If the first BWP overlaps with a band bandwidth of the fourth generation mobile communication technology network, the third generation mobile communication technology network, the second generation mobile communication technology network, the first generation mobile communication technology network, the satellite communication, the broadcast communication, the unlicensed frequency band, or the millimeter wave frequency band, the first BWP may perform forward compatibility and/or rate matching with the fourth generation mobile communication technology network, the third generation mobile communication technology network, the second generation mobile communication technology network, the first generation mobile communication technology network, the satellite communication, the broadcast communication, the unlicensed frequency band, or the millimeter wave frequency band.
For example: the network device simultaneously activates a first BWP and a second BWP for a terminal, wherein the first BWP is overlapped with a Long Term Evolution (LTE) frequency band bandwidth and is forward compatible and/or rate matched with the LTE, namely, the subcarrier interval can be set to be 15KHz, and NR data is not transmitted on resource blocks of existing reference signals (such as CRS) and control channels of the LTE; the second BWP is configured in a New Radio (NR) frequency band bandwidth, for example, the subcarrier spacing may be configured to be 30KHz/60KHz/120KHz, and other parameters are configured according to the actual usage of the NR bandwidth, where the parameters include: bandwidth size, resource starting position, resource size, subcarrier spacing, cyclic prefix format, control channel format, traffic channel format, antenna port mapping scheme or modulation and demodulation mode, etc.
In some embodiments, when the first BWP is forward compatible and/or rate matched with the fourth generation mobile communication technology network, the first BWP does not schedule symbols corresponding to reference signals of the fourth generation mobile communication technology network, and the frequency domain of the first BWP occupies the entire frequency band bandwidth of the fourth generation mobile communication technology network.
In an embodiment of the invention, the parameters comprise one or more of: bandwidth size, resource starting position, resource size, subcarrier spacing, cyclic prefix format, control channel format, traffic channel format, antenna port mapping scheme and modulation and demodulation mode.
In the embodiment of the present invention, each set of parameters may indicate different resource frequency bands or overlapped resource frequency bands; it will be appreciated that different parameters may be configured for different resource bands of the same BWP or different BWPs.
Step 302: and respectively processing the service on different resource frequency bands of the at least two BWPs or one BWP.
