It should be noted that, for a Multicast Broadcast Single Frequency Network (MBSFN) subframe, reception is generally performed on a fixed subframe or on a fixed partial symbol in a Long Term Evolution (LTE) terminal scheme at present. For different service scenarios, such a manner may cause the terminal device to receive unnecessary MBSFN subframes, resulting in an increase in power consumption for receiving MBSFN subframes.

In order to reduce the receiving power consumption of the MBSFN subframe, the embodiment of the application provides an MBSFN subframe receiving method. In order to better understand the MBSFN subframe receiving method provided in the embodiment of the present application, the MBSFN subframe receiving method is described in detail below.

Referring to fig. 2, fig. 2 is a flowchart of an MBSFN subframe receiving method according to an embodiment of the present application, where the MBSFN subframe receiving method includes steps 201 to 202. The method execution subject shown in fig. 2 may be a terminal device (for example, refer to fig. 1), or the subject may be a chip in the terminal device. The method shown in fig. 2 is executed by taking a terminal device as an example. Wherein:

201. the terminal equipment determines whether the MBSFN subframe has a receiving requirement of the control information.

In a possible implementation manner, the terminal device determines whether the MBSFN subframe has a need for receiving the control information, and the specific manner is as follows: when the MBSFN subframe does not transmit PDSCH service or the terminal equipment does not support the MBSFN subframe service, the terminal equipment determines whether the MBSFN subframe has the receiving requirement of the control information. For a scenario that the MBSFN subframe does not transmit the PDSCH service or the terminal device does not support the MBSFN subframe service, the terminal device receives an unnecessary MBSFN subframe, which may increase power consumption. Therefore, the terminal device needs to determine whether the MBSFN subframe has a need for receiving the control information. The Control Information may be Downlink Control Information (DCI) carried by a PDCCH or a Downlink HARQ Acknowledgement Indicator Channel (HICH) carried by a Hybrid Automatic Repeat reQuest (HARQ) Indicator Channel.

202. And if the MBSFN subframe has the receiving requirement of the control information, the terminal equipment receives the control information in the MBSFN subframe.

In the embodiment of the present application, the terminal device determines that there is a need for receiving the control information in the MBSFN subframe, that is, the terminal device has an uplink scheduling service, and therefore the terminal device needs to receive the control information in the MBSFN subframe.

In the method depicted in fig. 2, the terminal device determines whether the MBSFN subframe has a need for receiving control information; and under the condition that the MBSFN subframe has a receiving requirement of the control information, receiving the control information at the MBSFN subframe. Therefore, based on the method described in fig. 2, it is beneficial to reduce the reception power consumption of the MBSFN subframe.

Referring to fig. 3, fig. 3 is a flowchart of another MBSFN subframe receiving method according to an embodiment of the present application, where the MBSFN subframe receiving method includes steps 301 to 303. Step 302 and step 303 are specific implementations of step 202. The method execution subject shown in fig. 3 may be a terminal device (for example, as shown in fig. 1), or the subject may be a chip in the terminal device. The method execution subject shown in fig. 3 takes a terminal device as an example. Wherein:

301. the terminal equipment determines whether the MBSFN subframe has a receiving requirement of the control information or not based on the target information.

In an embodiment of the present application, the target information includes one or more of the following information: the number of symbols of a Physical Hybrid automatic repeat request Indicator Channel (PHICH) in the MBSFN subframe, the number of symbols of a PDCCH in the MBSFN subframe, and service scheduling information. The number of symbols of the PHICH in the MBSFN subframe and the number of symbols of the PDCCH in the MBSFN subframe may be configured by a higher layer, the PHICH is configured to receive an uplink Hybrid Automatic Repeat reQuest (HARQ) feedback, and the PDCCH is configured to transmit uplink and downlink scheduling control information. The service scheduling information may be used to indicate time information when the terminal device receives data. For the scene that the MBSFN subframe does not transmit PDSCH service or the terminal equipment does not support the MBSFN subframe service, because downlink service does not exist, downlink scheduling control information does not exist, and only the existence of uplink scheduling control information and uplink HARQ feedback needs to be identified. Since uplink scheduling is a synchronization mechanism (all scheduling is time-constrained), that is, the terminal device and the network device need to be synchronized, the terminal device can perform uplink scheduling. Therefore, whether the MBSFN subframe has the receiving requirement of the control information or not can be directly determined according to the high-level configuration and the service scheduling information.

302. The terminal equipment determines the first length of the control domain of the MBSFN subframe based on the target information.

In this embodiment of the present application, the first length is a maximum receiving length of a control domain of the MBSFN subframe, which is determined by the terminal device according to the target information, and the subsequent terminal device may receive the control information in the MBSFN subframe based on the first length.

303. If the MBSFN subframe has a receiving requirement of the control information, the terminal equipment receives the control information in the MBSFN subframe based on the first length.

In the embodiment of the application, under the condition that the MBSFN subframe has a receiving requirement of the control information, the terminal equipment receives the control information in the MBSFN subframe according to the first length. Based on the mode, the method is beneficial to reducing the receiving power consumption of the MBSFN subframe.

In the method depicted in fig. 3, the terminal device determines whether the MBSFN subframe has a need for receiving control information; when the MBSFN subframe has a need for receiving the control information, the terminal equipment receives the control information in the MBSFN subframe based on the first length of the control domain corresponding to the MBSFN subframe. Therefore, based on the method described in fig. 3, it is beneficial to reduce the reception power consumption of the MBSFN subframe.

Referring to fig. 4, fig. 4 is a flowchart of another MBSFN subframe receiving method according to an embodiment of the present application, where the MBSFN subframe receiving method includes steps 401 to 405. Step 403 and step 404 are specific implementations of step 303 described above. The method execution subject shown in fig. 4 may be a terminal device (for example, as shown in fig. 1), or the subject may be a chip in the terminal device. The method shown in fig. 4 is executed by taking a terminal device as an example. Wherein:

401. the terminal equipment determines whether the MBSFN subframe has a receiving requirement of the control information or not based on the target information.

Optionally, if the MBSFN subframe has a need for receiving control information, performing step 402 to step 404; if the MBSFN subframe does not have a requirement for receiving control information, step 405 is executed.

402. The terminal equipment determines the first length of the control domain of the MBSFN subframe based on the target information.

The specific implementation manners of step 401 and step 402 are the same as those of step 301 and step 302, and are not described herein again.

403. And the terminal equipment determines the actual length of the control domain based on the PCFICH of the MBSFN subframe.

In this embodiment of the present application, a Physical Control Format Indicator Channel (PCFICH) is used to indicate the length (number of symbols) of a Control domain, and a terminal device may determine the actual length of the Control domain according to the PCFICH of the MBSFN subframe.

404. And the terminal equipment receives control information in the MBSFN subframe based on the actual length and the first length.

In the embodiment of the application, after the terminal device determines the first length of the control domain of the MBSFN subframe according to the target information, and determines the actual length of the control domain according to the PCFICH of the MBSFN subframe, the terminal device receives the control information in the MBSFN subframe according to the first length and the actual length. Based on the mode, the method is beneficial to reducing the receiving power consumption of the MBSFN subframe.

In a possible implementation manner, if the actual length is smaller than the first length, the terminal device receives control information in the MBSFN subframe based on the actual length.

In the embodiment of the application, if the actual length of the control domain is smaller than the first length of the control domain, the terminal equipment immediately finishes the data receiving after recognizing that the actual data receiving of the control domain is finished. Based on the mode, the power consumption of the terminal equipment is reduced.

405. And if the MBSFN subframe does not have the receiving requirement of the control information, the terminal equipment does not receive the MBSFN subframe.

Exemplarily, as shown in fig. 5, fig. 5 is a schematic diagram of MBSFN subframe reception provided in the embodiment of the present application. In this example, the MBSFN subframe includes a preset control field and a preset data field, the length of the preset receive is the first length of the control field, and the length of the actual receive is the actual length of the control field. And when the MBSFN subframe N has no receiving requirement of the control information, the terminal equipment does not receive the MBSFN subframe N. And when the terminal equipment identifies that the actual receiving in the control domain is finished, immediately controlling the receiving to be finished.

In the method described in fig. 4, the terminal device determines whether there is a need for receiving control information in the MBSFN subframe; when the MBSFN subframe has a receiving requirement of the control information, the terminal equipment receives the control information in the MBSFN subframe based on the first length and the actual length of the control domain corresponding to the MBSFN subframe. Therefore, based on the method described in fig. 4, it is beneficial to reduce the reception power consumption of the MBSFN subframe.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a communication device according to an embodiment of the present application. The apparatus may be a terminal device, an apparatus in the terminal device, or an apparatus capable of being used in cooperation with the terminal device. The communication device 60 shown in fig. 6 may include a processing unit 601 and a communication unit 602. The processing unit 601 is configured to perform data processing.
