Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
A method of channel allocation, the method comprising: detecting a data channel distributed to a mobile terminal by a high-frequency base station when the mobile terminal moves to an edge area covered by the high-frequency base station; when the data channel allocated by the high-frequency base station is an uplink data channel, prohibiting the low-frequency base station from allocating the uplink data channel to the mobile terminal; and when the data channel allocated by the high-frequency base station is a downlink data channel, controlling the low-frequency base station to allocate an uplink data channel to the mobile terminal.
As shown in fig. 1, fig. 1 is a schematic flow chart of a channel allocation method according to an embodiment of the present application, and a specific flow of the channel allocation method may be as follows:
101. and detecting a data channel distributed to the mobile terminal by the high-frequency base station when the mobile terminal moves to an edge area covered by the high-frequency base station.
In the embodiment of the invention, before the mobile terminal moves to the edge area covered by the high-frequency base station, the connection between the mobile terminal and the high-frequency base station and the connection between the mobile terminal and the low-frequency base station are established. Specifically, whether the mobile terminal is connected to the high-frequency base station is detected, if yes, whether the mobile terminal is in a double-connection state with the high-frequency base station and the low-frequency base station is detected, and if yes, whether the mobile terminal is connected with the high-frequency base station and the low-frequency base station is judged. The high-frequency base station can be a base station of a Sub-6G frequency band or a base station of a millimeter wave frequency band. The low-frequency base station may be a base station of 4G LTE frequency band, or may be a base station of 5G NR low frequency, for example, a base station of 5G N8 frequency band, where the frequency range of the 5G N8 frequency band is around 900M, and the coverage area of the base station of 5G N8 frequency band is far greater than that of the base station supporting 3.5GHz frequency band.
The edge area covered by the high frequency base station refers to an edge area of the high frequency base station with respect to the coverage of the mobile terminal. Since the transmission power of the high-frequency base station is large and is far greater than that of the mobile terminal, the coverage area of the high-frequency base station relative to the mobile terminal mainly depends on the transmission frequency of the mobile terminal. When the mobile terminal is far away from the high-frequency base station, the transmitting power of the mobile terminal is increased, so that whether the mobile terminal is positioned in the edge area covered by the high-frequency base station can be judged by detecting the transmitting power of the mobile terminal.
Specifically, the method further comprises:
detecting the transmitting power of the mobile terminal in real time;
when the transmitting power of the mobile terminal exceeds a power threshold value, determining that the mobile terminal moves to an edge area covered by the high-frequency base station; the power threshold is the difference between the maximum transmitting power of the mobile terminal and a preset fixed value.
It should be noted that, the maximum transmission power of different mobile terminals is different, for example, the maximum transmission power of a mobile terminal may be 20dBm, 23dBm, 26dBm, or the like. According to the maximum transmission power of the mobile terminal, a power threshold corresponding to the mobile terminal can be set, the power threshold is obtained by subtracting a fixed value from the maximum transmission power of the mobile terminal, the fixed value can be between 1dB and 3dB, for example, the mobile terminal with the maximum transmission power of 20dBm, the power threshold can be 18dBm, the mobile terminal with the maximum transmission power of 23dBm, the power threshold can be 21dBm, the mobile terminal with the maximum transmission power of 26dBm, and the power threshold can be 24dBm. Different mobile terminals can report maximum transmitting power to the high-frequency base station, such as P1, P2, … and Pn, and the high-frequency base station sets power thresholds of corresponding mobile terminals, such as X1, X2, … and Xn, according to the maximum transmitting power reported by the different mobile terminals.
When the mobile terminal is far away from the high-frequency base station, the transmitting power of the mobile terminal is continuously increased. When the mobile terminal detects that the transmitting power of the mobile terminal does not exceed the corresponding power threshold value, the mobile terminal is determined to move in a non-edge area covered by the high-frequency base station, the high-frequency base station allocates an uplink data channel (Physical Uplink shared channel, PUSCH) or a downlink data channel (Physical Downlink shared channel, PDSCH) to the mobile terminal according to the uplink and downlink time slot ratio, and the low-frequency base station allocates the uplink data channel to the mobile terminal. For example, as shown in fig. 2, the high frequency base station sequentially allocates 3 downlink timeslots, 1 uplink timeslot and 1 downlink timeslot to the mobile terminal, and the low frequency base station sequentially allocates 5 uplink timeslots to the mobile terminal, where the uplink timeslots are used for allocating uplink data channels and the downlink timeslots are used for allocating downlink data channels. Because the mobile terminal is positioned in the non-edge area covered by the high-frequency base station, the transmitting power of the mobile terminal is lower, and uplink data can be transmitted through an uplink data channel distributed by the high-frequency base station and an uplink data channel distributed by the low-frequency base station.
When the mobile terminal detects that the transmitting power exceeds the corresponding power threshold, the mobile terminal moves to the edge area covered by the high-frequency base station, and the mobile terminal can enter a channel switching mode. After the mobile terminal enters a channel switching mode, the high-frequency base station still distributes an uplink data channel or a downlink data channel to the mobile terminal according to the uplink and downlink time slot ratio. The mobile terminal can detect the data channel allocated by the high-frequency base station, and the mobile terminal can know the type of the data channel which is about to enter according to the data channel allocated by the high-frequency base station.
102. And when the data channel allocated by the high-frequency base station is an uplink data channel, prohibiting the low-frequency base station from allocating the uplink data channel to the mobile terminal.
In the embodiment of the invention, if the mobile terminal detects that the data channel allocated by the high-frequency base station is an uplink data channel, the mobile terminal is indicated to enter the uplink data channel provided by the high-frequency base station, and because the mobile terminal is positioned in the edge area covered by the high-frequency base station, in order to avoid reducing the coverage area of the high-frequency base station relative to the mobile terminal, the low-frequency base station is forbidden to allocate the uplink data channel to the mobile terminal during the period that the mobile terminal enters the uplink data channel allocated by the high-frequency base station.
Specifically, when the mobile terminal detects an uplink data channel allocated by the high-frequency base station, information is sent to the low-frequency base station to inform the low-frequency base station, so that the low-frequency base station stops allocating the uplink data channel to the mobile terminal. At this time, the mobile terminal transmits uplink data only on the uplink data channel allocated by the high frequency base station. Although the low frequency base station stops allocating the uplink data channel to the mobile terminal, the low frequency base station still allocates the uplink control channel (Physical Uplink control channel, PUCCH) to the mobile terminal, i.e. the mobile terminal and the low frequency base station remain connected through the PUCCH.
103. And when the data channel allocated by the high-frequency base station is a downlink data channel, controlling the low-frequency base station to allocate an uplink data channel to the mobile terminal.
In the embodiment of the invention, if the mobile terminal detects that the data channel allocated by the high-frequency base station is a downlink data channel, the mobile terminal is indicated to enter the downlink data channel provided by the high-frequency base station, and in order to keep a higher uplink rate, the low-frequency base station is controlled to allocate the uplink data channel to the mobile terminal during the period that the mobile terminal enters the downlink data channel allocated by the high-frequency base station.
Specifically, when the mobile terminal detects a downlink data channel allocated by the high-frequency base station, information is sent to the low-frequency base station to inform the low-frequency base station, so that the low-frequency base station allocates an uplink data channel to the mobile terminal. At this time, the high frequency base station transmits downlink data to the mobile terminal through the downlink data channel, and the mobile terminal transmits uplink data on the uplink data channel allocated by the low frequency base station. Meanwhile, the low-frequency base station distributes an uplink control channel to the mobile terminal, so that the high-frequency base station can transmit feedback information on the uplink control channel distributed by the low-frequency base station while transmitting downlink data to the mobile terminal. The feedback information includes ACK information or NACK information, where ACK information indicates that correct information was received and NCK information indicates that incorrect information was received without acknowledgement. Compared with the prior art that the mobile terminal can only send feedback information to the 5G base station in the uplink time slot of the 5G base station, the embodiment effectively reduces message time delay.
For example, as shown in fig. 3, the high frequency base station sequentially allocates 3 downlink time slots D, 1 uplink time slot U, 3 downlink time slots D, and 1 uplink time slot U to the mobile terminal. When the high-frequency base station allocates the downlink time slot D, the low-frequency base station allocates the uplink time slot U to the mobile terminal, and when the high-frequency base station allocates the uplink time slot U, the low-frequency base station does not allocate the time slot to the mobile terminal. In addition, the high frequency base station may also allocate a special time slot (not shown in the figure) to the mobile terminal, and the low frequency base station allocates an uplink time slot U to the mobile terminal when the high frequency base station allocates the special time slot.
As shown in fig. 4, fig. 4 is a schematic flowchart of a specific flow of a channel allocation method according to an embodiment of the present application, where the specific flow of the channel allocation method may be as follows:
201. and establishing connection between the mobile terminal and the high-frequency base station and the low-frequency base station.
The mobile terminal is respectively connected with the high-frequency base station and the low-frequency base station, and the coverage area of the high-frequency base station is smaller than that of the low-frequency base station. The high frequency base station is also connected to the low frequency base station for connection to the core network via the low frequency base station.
202. And setting a power threshold according to the maximum transmission power of the mobile terminal.
And setting a corresponding power threshold according to the actual situation of the mobile terminal. The mobile terminal may report its maximum transmission power to the high frequency base station, and the high frequency base station sets a power threshold for the mobile terminal according to the maximum transmission power reported by the mobile terminal, for example, subtracts 2dBm or 3dBm based on the maximum transmission power of the mobile terminal, to obtain a corresponding power threshold.
203. When the transmission power of the mobile terminal exceeds the power threshold, it is detected whether the high frequency base station is about to allocate an uplink data channel to the mobile terminal, if so, step 204 is executed, and if not, step 205 is executed.
And when the transmitting power of the mobile terminal exceeds the power threshold, indicating that the mobile terminal moves to an edge area covered by the high-frequency base station. The high frequency base station allocates an uplink data channel to the mobile terminal in an uplink time slot, so that the detection of the uplink data channel can be achieved by detecting whether the mobile terminal is about to enter the uplink time slot of the high frequency base station.
204. The low frequency base station is prohibited from allocating an uplink data channel to the mobile terminal.
When the high-frequency base station allocates an uplink data channel to the mobile terminal, the mobile terminal transmits uplink data on the uplink data channel allocated by the high-frequency base station and stops data transmission with the low-frequency base station.
205. And controlling the low-frequency base station to allocate an uplink data channel to the mobile terminal.
When the high-frequency base station allocates a downlink data channel to the mobile terminal, the high-frequency base station transmits downlink data to the mobile terminal through the downlink data channel, the mobile terminal transmits uplink data on an uplink data channel allocated by the low-frequency base station, and meanwhile, the low-frequency base station allocates an uplink control channel to the mobile terminal, and the mobile terminal transmits feedback information on the uplink control channel allocated by the low-frequency base station.
As can be seen from the foregoing, the channel allocation method provided by the present application can detect a data channel allocated to a mobile terminal by a high frequency base station when the mobile terminal moves to an edge area covered by the high frequency base station, if the data channel is an uplink data channel, prohibit a low frequency base station from allocating an uplink data channel to the mobile terminal, and if the data channel is a downlink data channel, control the low frequency base station to allocate an uplink data channel to the mobile terminal so as to maintain a higher uplink rate without affecting the coverage of the high frequency base station relative to the mobile terminal.
