Abstract

A method for data transmission of a multi-card UE is provided. The multi-card UE has at least a first subscriber identity module (SIM) card and a second SIM card, the first SIM card is in a connected status with a network. The method includes: determining a wireless operation demand of the second SIM card, and requesting a transmission time gap from the network according to the wireless operation demand, for enabling the second SIM card to execute a wireless operation in the transmission time gap. The method further includes generating a gap adjustment request according to the wireless operation executed by the second SIM card, and sending the gap adjustment request to the network, for enabling the network to adjust allocated transmission time gap according to the gap adjustment request.

Claims (39)

1 . A method for data transmission of a multi-card UE, wherein the multi-card UE has at least a first subscriber identity module (SIM) card and a second SIM card, the first SIM card is in a connected status with a network, the method comprises:

determining a wireless operation demand of the second SIM card, and requesting a transmission time gap from the network according to the wireless operation demand, for enabling the second SIM card to execute a wireless operation in the transmission time gap; and

generating a gap adjustment request according to the wireless operation executed by the second SIM card, and sending the gap adjustment request to the network, for enabling the network to adjust allocated transmission time gap according to the gap adjustment request.

2 . The method according to claim 1 , wherein the wireless operation comprises at least one of paging reception, random access, system information reception, reference signal measurement and cell search.

3 . The method according to claim 2 , wherein based on the wireless operation being paging reception, said generating the gap adjustment request according to the wireless operation comprises:

generating, in response to a paging indicator received by the second SIM card indicating not receiving a secondary common control channel, the gap adjustment request to release a time gap allocated for receiving the secondary common control channel.

4 . The method according to claim 1 , wherein said generating the gap adjustment request according to the wireless operation comprises:

generating, in response to detecting that the second SIM card needs message retransmission, the gap adjustment request to request the network to extend the transmission time gap.

5 . The method according to claim 1 , wherein said generating the gap adjustment request according to the wireless operation comprises:

generating, in response to detecting that the second SIM card completes the wireless operation early, the gap adjustment request to release remaining transmission time gap.

6 . The method according to claim 1 , wherein said sending the gap adjustment request comprises:

sending the gap adjustment request to the network using dedicated resources.

7 . The method according to claim 1 , wherein the gap adjustment request is sent through physical layer resources or through MAC CE.

8 . The method according to claim 7 , wherein the physical layer resources comprise:

PUCCH, or

PRACH, or

PUSCH, or

a combination of PRACH and PUSCH.

9 . A method for data transmission of a multi-card UE, comprising:

allocating a transmission time gap for a first subscriber identity module (SIM) card according to a wireless operation demand of a second SIM card of a multi-card UE, for enabling the second SIM card to execute a wireless operation in the transmission time gap; and

adjusting the allocated transmission time gap according to a gap adjustment request in response to receiving the gap adjustment request sent by the multi-card UE;

wherein the gap adjustment request is generated according to the wireless operation, the multi-card UE has at least the first SIM card and the second SIM card, and the first SIM card is in a connected status with a network.

10 . The method according to claim 9 , wherein the wireless operation comprises at least one of paging reception, random access, system information reception, reference signal measurement and cell search.

11 . The method according to claim 10 , wherein based on the wireless operation being paging reception, said adjusting the allocated transmission time gap according to the gap adjustment request comprises:

releasing, in response to a paging indicator received by the second SIM card indicating not receiving a secondary common control channel, a time gap allocated for receiving the secondary common control channel.

12 . The method according to claim 9 , further comprising:

allocating dedicated resources for the first SIM card, so that the first SIM card sends the gap adjustment request using the dedicated resources.

13 . The method according to claim 9 , wherein the gap adjustment request is sent through physical layer resources or through MAC CE.

14 . The method according to claim 13 , wherein the physical layer resource comprises:

PUCCH, or

PRACH, or

PUSCH, or

a combination of PRACH and PUSCH.

15 . A non-transitory storage medium, storing computer instructions, wherein the computer instructions, when being executed, perform the method according to claim 1 .

16 . A multi-card user equipment having at least a first subscriber identity module (SIM) card in a connected status with a network and a second SIM card, comprising a memory and a processor, wherein the memory stores one or more programs, the one or more programs comprising computer instructions, which, when executed by the processor, cause the processor to:

determine a wireless operation demand of the second SIM card, and request a transmission time gap from the network according to the wireless operation demand, for enabling the second SIM card to execute a wireless operation in the transmission time gap; and

generate a gap adjustment request according to the wireless operation executed by the second SIM card, and send the gap adjustment request to the network, for enabling the network to adjust allocated transmission time gap according to the gap adjustment request.

17 . The method according to claim 1 , wherein the gap adjustment request is used to request to release the transmission time gap or extend the time of the transmission time gap.

18 . A non-transitory storage medium, storing computer instructions, wherein the computer instructions, when being executed, perform the method according to claim 9 .
