Description
Technical Field

The LTE system introduces Orthogonal Frequency Division Multiplexing (OFDM) and multiple-Input multiple-Output (MIMO) key technologies, which significantly increases the spectrum efficiency and data transmission rate, and supports multiple bandwidth allocation: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz and the like, and supports the global mainstream 2G/3G frequency band and some newly-added frequency bands, thereby the frequency spectrum allocation is more flexible, and the system capacity and the coverage are also obviously improved. The LTE system network architecture is more flat and simplified, and the complexity of network nodes and the system is reduced, so that the system time delay is reduced, and the network deployment and maintenance cost is also reduced. The LTE system supports interoperation with other 3GPP systems.

The first card can transmit data, and the second card receives paging message, system message and cell measurement and search service regularly.
However, since only one Radio Frequency (RF) module is configured in the User Equipment (UE), when the second card uses the RF module to perform the above service, the first card cannot use the RF module to perform data transmission with the base station, so that the base station senses that the uplink signal of the first card is poor, thereby reducing uplink scheduling for the user equipment.

Detailed Description
As described in the background art, two cards, such as two Subscriber Identity Module (SIM) cards, are installed in a multi-card user equipment, where a first card supports LTE data services and a second card supports Global System for Mobile Communication (GSM) telephone services. The first card can transmit data, and the second card receives paging message, system message and cell measurement and search service regularly.
In the LTE system, a multi-card user equipment having two cards is configured with only one RF module, and the two cards can perform corresponding services when they have to obtain the right to use the RF module. For example, please refer to fig. 1, suppose that the first card obtains the usage right of the RF module, i.e. the time period for acquiring the RF resource, in the PG time period, and releases the RF module in the Gap time period, i.e. the second card obtains the usage right of the RF module in the Gap time period. The durations of the PG periods and the Gap periods described above may vary, but always alternate.
Under the condition that the PG time period and the Gap time period alternately appear, when the second card RF module receives paging messages and system messages and performs cell measurement and search services, the first card cannot use the RF module, so that the uplink signal of the first card acquired by the base station is poor. At this time, the base station reduces uplink scheduling for the user equipment. After the first card reacquires the right to use the RF module, the base station only slowly increases the uplink scheduling for the user equipment, so that the uplink data transmission rate of the first card is affected.
In order to solve the above problem, in the technical solution in the embodiment of the present invention, the multi-card user equipment instructs the base station to stop uplink scheduling of the base station when the first card is to release the RF resource, and instructs the base station to resume uplink scheduling of the base station in the time period when the first card reacquires the RF resource, so that uplink data transmission of the first card is not affected by the time period when the RF resource is released, thereby improving the rate of uplink data transmission and improving the user experience.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 2 shows a flowchart of an uplink data transmission method of a multi-card user equipment in an embodiment of the present invention. Referring to fig. 2, in a specific implementation, the uplink data transmission method of the multi-card user equipment in the embodiment of the present invention may include the following steps:
step S201: and in the time period of acquiring the RF resources, transmitting indication information for stopping uplink scheduling to the base station by using a preset number of TTIs before the RF resources are released so as to indicate the base station to stop the uplink scheduling of the base station.
Referring to fig. 3, a time period PG during which the first card acquires the RF resource for uplink data transmission is divided into a first stage PG1 and a second stage PG 2. In the first stage PG1, the first card in the multi-card user equipment normally transmits uplink data to the base station. In the second stage PG2, the first card in the multi-card ue sends the indication information for stopping uplink scheduling to the base station, so as to instruct the base station to stop uplink scheduling for itself. According to different protocols used for uplink data transmission, the multi-card user equipment may send, to the base station, the indication information for stopping uplink scheduling in a manner of sending, to the base station, a conventional Buffer Status Report (BSR) with a Buffer Size (Buffer Size) of zero, a periodic Buffer Status Report (BSR), or a Padding BSR, so that when the base station obtains the conventional Buffer Status Report (Buffer Status Report, BSR) with a Buffer Size (Buffer Size) of zero, the periodic Buffer Status Report, or the Padding Buffer Status Report, it is determined that the sum of uplink data that can be sent by all logical channel groups of the multi-card user equipment is zero, that is, no valid packet is sent, and thus the base station may reduce or even stop uplink scheduling for the multi-card user equipment.
In an implementation, the second phase PG2 is a predetermined number of Transmission Time Intervals (TTIs) before the RF resources are released, that is, a predetermined number of TTIs before the Gap period comes. In the preset number of TTIs, for example, 8 TTIs, the multi-card user equipment may generate corresponding indication information for stopping uplink scheduling, and send the generated indication information for stopping uplink scheduling to the base station, so that the base station learns that the buffer data packets of all the current logical channels of the multi-card user equipment are empty, that is, in the preset number of TTIs before the Gap time period comes, the multi-card user equipment will not send valid data packets, and thus the base station stops performing uplink scheduling on itself.
Meanwhile, when the multi-card user equipment receives uplink scheduling information sent by the base station in a preset number of TTIs before the RF resources are released, the uplink MAC TB blocks are packaged according to the condition that the buffer data packets of all the current logic channels are empty. In other words, when the multi-card user equipment performs the second stage PG2, after receiving the uplink scheduling information of the base station, the first card only sends a padding (padding) packet to the base station, so that the base station knows that no uplink data needs to be transmitted currently, and thus the base station can stop performing uplink scheduling on itself.
Step S202: and when the RF resource is acquired next time, sending uplink scheduling request information to the base station so that the base station recovers uplink scheduling of the base station.
In a specific implementation, when the first card reacquires the RF resource and the second card releases the RF resource, the multi-card user equipment may immediately send uplink Scheduling request (Scheduling Report) information to the base station when entering the first stage PG1, so that the base station knows that there is uplink data to be sent currently, and the base station resumes uplink Scheduling for itself. When the base station acquires the RF resource, the multi-card user equipment transmits a BSR to the base station according to a state of Radio Link Control (RLC) layer buffer, and performs uplink data packing.
In an embodiment of the present invention, the multi-card user equipment may start to generate the SR information several TTIs before entering the first stage PG1, and once the RF resource is acquired, that is, at the initial time of entering the first stage PG1, the generated SR information may be sent to the base station, so that the base station may know that there is uplink data to be sent as early as possible, and further, the base station may perform uplink scheduling on itself as soon as possible. When acquiring the RF resource, the multi-card user equipment may normally send a BSR to the base station according to a state of Radio Link Control (RLC) layer buffer, and perform uplink data packing.
Of course, in another embodiment of the present invention, the multi-card user equipment may also start to generate corresponding SR information only when entering the initial time of the first stage PG1, and then send the generated SR information to the base station, so that the base station resumes performing uplink scheduling on itself, which is not limited herein.
As can be seen from the introduction of the above description, in the uplink data transmission method for the multi-card user equipment in the embodiment of the present invention, by using information interaction between the multi-card user equipment and the base station, the base station stops performing uplink scheduling on the multi-card user equipment in the time period when the first card of the multi-card user equipment releases the RF resource, and resumes performing uplink scheduling on the multi-card user equipment in the time period when the first card reacquires the RF resource, so that the base station does not reduce scheduling on the user equipment with the multi-card user equipment that is unavailable because the first card is in the RF resource state in the Gap time period, thereby increasing the data amount of uplink data transmission of the multi-card user equipment and improving the user experience.
The results obtained by testing in a plurality of external field environments by the inventor of the present application show that the transmission rate of the uplink data of the multi-card user equipment can be increased by more than 40% by using the uplink data transmission method of the multi-card user equipment in the embodiment of the present invention, and the effect is significant.
It should be noted here that the type of card installed in the multi-card user equipment in the embodiment of the present invention is not limited.
