[0021] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0031] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain it through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain it through C; it can also mean that there is an association between A and B.

[0032] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0033] Optionally, the configuration parameters or configuration information or configuration signaling in the embodiment of the present application include at least one of Radio Resource Control (RRC) signaling and Media Access Control Control Element (MAC CE).

[0034] The embodiments of the present application are described in conjunction with terminal devices and network devices, wherein the terminal device may also be referred to as user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (STATION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a next-generation communication system, such as a terminal device in a NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network.

[0035] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0036] A network device may be a device used to communicate with a mobile device. The network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a network device or base station (gNB) in a vehicle-mounted device, a wearable device, and an NR network, or a network device in a future evolved PLMN network, etc.

[0037] In the embodiments of the present application, the network device may have a mobile feature. For example, the network device may be a mobile device. Alternatively, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station located in a location such as land or water.

[0038] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to a network device (for example, a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, picocells, femtocells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0039] In the NR system, a terminal device can have the following Radio Resource Control (RRC) states:

[0040] RRC_IDLE state: In this state, mobility is based on cell selection and reselection by the terminal device. Paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no terminal device Access Stratum (AS) context on the base station side, and no RRC connection exists.

[0041] RRC_CONNECTED state: In this state, an RRC connection exists between the terminal device and the base station, and a terminal device AS context exists between the base station and the terminal device. The base station knows the terminal device's location at the cell level. Mobility is controlled by the base station. Unicast data can be transmitted between the terminal device and the base station.

[0042] RRC_INACTIVE (inactive) state: In this state, mobility is based on cell selection and reselection of the terminal device, there is a connection between CN-NR, the terminal device AS context exists on a base station, paging is triggered by the Radio Access Network (RAN), and the RAN-based paging area is managed by the RAN. The base station knows the location of the terminal device based on the RAN paging area level.

[0043] In some scenarios, in order to save power for the terminal, the concept of discontinuous reception (DRX) is proposed. Specifically, the network device can configure the terminal device to wake up (DRXON) at a time predicted by the network and monitor the physical downlink control channel (PDCCH). At the same time, the network can also configure the terminal device to sleep (DRXOFF) at a time predicted by the network. Therefore, if the network device has data to transmit to the terminal device, the network device can schedule the terminal device during the time when the terminal device is in DRXON, and during the DRXOFF time, the terminal power consumption can be reduced because the radio frequency is turned off.

[0044] Connected mode DRX (CDRX) is the DRX function of the UE in the connected state. Specifically, the UE monitors the channel during the CDRX activation period (i.e., during the on duration). For example, if the UE is configured with 4 receive antennas, it uses the 4 receive antennas to receive PDCCH during the activation period, or, after receiving the DCI scheduling, uses the 4 receive antennas to receive PDSCH, such as Figure 2 As shown, this results in excessive power consumption of the terminal device. Therefore, how to perform channel reception to reduce the power consumption of the terminal device is an issue that needs to be urgently addressed.

[0045] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0046] Figure 3 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application, as shown in FIG. Figure 3 As shown, the method 300 includes the following contents:

[0047] S310, the terminal device uses a target number of receiving antennas to receive a target channel, where the target number is determined based on first information, and the first information is related to the transmission requirements of the target channel and / or the channel conditions of the terminal device.

[0048] In some embodiments, the first information includes at least one of the following:

[0049] a channel type of the target channel;

[0050] Mobility information of the terminal device;

[0051] Historical scheduling information of the terminal device;

[0052] Historical channel quality information between the terminal device and the network device.

[0053] In some embodiments, the channel type of the target channel is a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

[0054] In some embodiments, the transmission requirements of the target channel may include but are not limited to the requirements of the target channel for the channel environment, the number of transmission layers of the target channel, etc.

[0055] In some embodiments, the historical scheduling information of the terminal device includes:

[0056] The terminal device's latest N scheduling information, where N is a positive integer, is the scheduling information received by the terminal device for the latest N times.

[0057] Optionally, the scheduling information includes information on the number of layers of the PDSCH that the terminal device is scheduled to receive.

[0058] In some embodiments, the N is predefined, or configured by the network device, or determined by the terminal device.

[0059] In some embodiments, the mobility information of the terminal device and the historical channel quality information are used to determine current channel quality information between the terminal device and the network device, and / or future channel quality information between the terminal device and the network device.

[0060] In some embodiments, the first information includes a channel type of the target channel, and the target quantity is determined based on the first information, including:

[0061] If the target channel is a PDCCH, the target number is a first number; and / or

[0062] If the target channel is a PDSCH, the target number is a second number;

[0063] The first quantity is less than or equal to the second quantity.

[0064] By way of example and not limitation, the first number is 1 or 2, and the second number is 2 or 4.

[0065] Since PDCCH has lower requirements for the channel environment and the number of transmission layers is usually one, PDSCH has higher requirements for the channel environment and is more sensitive to the signal-to-noise ratio (SNR), and the number of transmission layers is usually 1 to 4. Therefore, a smaller number of receiving antennas can be used to receive PDCCH, and a larger number of receiving antennas can be used to receive PDSCH. This is beneficial to reducing the power consumption of terminal equipment while ensuring the channel reception performance.

[0066] In some embodiments, the first information includes channel quality information between the terminal device and the network device, and the target number is determined based on the first information, including:

[0067] If the channel quality information between the terminal device and the network device is higher than a first threshold, the target number is a third number; and / or

[0068] If the channel quality information between the terminal device and the network device is lower than the first threshold, the target number is the fourth number;

[0069] The third number is smaller than the fourth number.

[0070] When the channel conditions of the terminal device are better, a smaller number of receiving antennas are used for channel reception. When the channel conditions of the terminal device are worse, a larger number of receiving antennas are used for channel reception. This is beneficial to balancing the channel reception performance and the power consumption of the terminal device.

[0071] As an example and not a limitation, the third number is 1 or 2, and the fourth number is 2 or 4.

[0072] As a specific example, for PDCCH, when the channel quality information between the terminal device and the network device is higher than the first threshold, a third number of receiving antennas is used to receive PDCCH, or, when the channel quality information between the terminal device and the network device is lower than the first threshold, a fourth number of receiving antennas is used to receive PDCCH, for example, the third number can be 1 and the fourth number can be 2.

[0073] As another specific example, for PDSCH, when the channel quality information between the terminal device and the network device is higher than the first threshold, a third number of receiving antennas is used to receive PDSCH, or, when the channel quality information between the terminal device and the network device is lower than the first threshold, a fourth number of receiving antennas is used to receive PDSCH, for example, the third number can be 2 and the fourth number can be 4.

[0074] Since PDCCH has lower requirements for the channel environment, while PDSCH has higher requirements for the channel environment, under the same channel conditions, using a larger number of receiving antennas to receive PDSCH and a smaller number of receiving antennas to receive PDCCH is beneficial to balancing the channel reception performance and the power consumption of the terminal equipment.

[0075] In some embodiments, the first threshold may be predefined, or configured by a network device, or determined by a terminal device.

[0076] In some embodiments, the channel quality information between the terminal device and the network device may be the current channel quality information between the terminal device and the network device, that is, the current channel condition of the terminal device.

[0077] Optionally, the current channel quality information between the terminal device and the network device may be determined based on historical channel quality information between the terminal device and the network device and mobility information of the terminal device.

[0078] In some embodiments, the target quantity is determined based on the first information, including:

[0079] If the target channel is a PDCCH, the target quantity is determined based on historical channel quality information between the terminal device and the network device and / or mobility information of the terminal device.

[0080] For example, the terminal device may determine the current channel quality information between the terminal device and the network device based on the historical channel quality information and the mobility information of the terminal device, and further determine the target number based on the current channel quality information.

[0081] As an example, when the current channel quality information is higher than the first threshold, the third number of receiving antennas is used to receive the PDCCH, or when the current channel quality information is lower than the first threshold, the fourth number of receiving antennas is used to receive the PDCCH.

[0082] As an example and not a limitation, the third number is 1 or 2, and the fourth number is 2 or 4.

[0083] In some embodiments, the target quantity is determined based on the first information, including:

[0084] If the target channel is PDSCH, the target quantity is determined according to the historical scheduling information of the terminal device.

[0085] The historical scheduling information of the terminal device may include the layer number information of the PDSCH that the terminal device is scheduled to receive. Based on the historical scheduling information, the range of the layer number of the PDSCH that the terminal device is scheduled to receive can be determined, and the number of receiving antennas used to receive the PDSCH can be further determined based on this. This is conducive to reducing the power consumption of the terminal device while ensuring the reception performance of the PDSCH.

[0086] In some embodiments, if the number of layers of PDSCH scheduled to be received by the terminal device in the last N times is less than or equal to the first number of layers, the target number is equal to the first number of layers.

[0087] For example, if the number of layers of the PDSCH scheduled to be received by the terminal device in the last N times is less than or equal to 2, two receiving antennas can be used to receive the PDSCH.

[0088] Combine Figure 4 , describing a channel receiving method according to an embodiment of the present application.

[0089] For example, during the on duration, the terminal device can use 2 receiving antennas to receive PDCCH, and switch to using 4 receiving antennas to receive PDSCH when receiving the DCI scheduling, or, when the channel quality deteriorates (for example, below the first threshold), the mobility becomes higher, and the number of transmission layers of the scheduled PDSCH is greater than 2, switch to using 4 receiving antennas for channel reception. Alternatively, when the channel quality is good (for example, above the first threshold) or the mobility is low, switch to using 1 receiving antenna to receive PDCCH. By comparison Figure 2 and Figure 4 It can be seen that performing channel reception based on the channel reception method of the embodiment of the present application is beneficial to reducing the power consumption of the terminal device while ensuring the channel reception performance.

[0090] It has been verified that the target channel reception method provided in the embodiment of the present application can reduce power consumption by 50% to 75% when receiving PDCCH, and can reduce power consumption by about 50% when receiving PDSCH.

[0091] In summary, in an embodiment of the present application, the terminal device can determine the number of receiving antennas used to receive the target channel based on the channel type of the target channel to be received in combination with the transmission requirements of the target channel and / or the channel conditions in which the terminal device is located, which is beneficial to reducing the power consumption of the terminal device while ensuring the receiving performance of the target channel.
