The switching method of the antenna switching configuration provided by the embodiment of the present disclosure can be applied to the wireless communication system shown in fig. 1. Referring to fig. 1, the wireless communication system includes a network device and a terminal. The terminal is connected with the network equipment through wireless resources and carries out data transmission.

It is understood that the wireless communication system shown in fig. 1 is only for illustrative purposes, and other network devices, such as a core network device, a wireless relay device, a wireless backhaul device, etc., may also be included in the wireless communication system, which is not shown in fig. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the embodiment of the present disclosure is a network providing a wireless communication function. Wireless communication systems may employ different communication technologies, such as Code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal Frequency Division Multiple Access (OFDMA), single Carrier FDMA, carrier Sense Multiple Access with Collision Avoidance (SC-FDMA). Networks can be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, according to factors such as capacity, rate, and delay of different networks, and a 5G network can also be referred to as a New Radio Network (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (enb), a home base station, an Access Point (AP), a wireless relay node, a wireless backhaul node, a Transmission Point (TP), a Transmission and Reception Point (TRP) in a wireless fidelity (WIFI) system, and the like, and may also be a gNB in an NR system, or may also be a component or a part of a device constituting the base station. It should be understood that, in the embodiments of the present disclosure, the specific technology and the specific device form adopted by the network device are not limited. In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). Further, when a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device.

Further, the Terminal referred to in this disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, and is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device having a wireless connection function, a vehicle-mounted device, and the like. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Customer Premise Equipment (CPE), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or an in-vehicle device. Further, when being a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and the specific device forms adopted by the terminal.

In the related art, MIMO technology is adopted to increase the data transmission rate and to increase the data throughput and the signal-to-noise ratio. MIMO refers to using multiple transmitting antennas and multiple receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the multiple antennas at the transmitting end and the receiving end, thereby improving data throughput and signal-to-noise ratio, and improving system performance and communication quality. The multi-antenna multi-transmission multi-reception system can fully utilize space resources, realize multi-transmission and multi-reception through a plurality of antennas, and improve the system channel capacity by times under the condition of not increasing frequency spectrum resources and antenna transmitting power.

MIMO technology is increasingly being applied to a variety of high data rate technologies, including WiFi,4G Long Term Evolution (LTE), and 5G NR. A MIMO system is the parallel transmission of multiple signal streams over the air. The data stream input at the transmitting terminal becomes several parallel symbol streams, which are transmitted from Nt antennas simultaneously; the receiving end receives the signals from the Nr receiving antennas and restores the original signals, as shown in fig. 2.

In order to support that downlink information can be effectively acquired through a channel under various terminal transceiving capabilities, different antenna switching configurations are set for a terminal in a communication system. The antenna switching capability of the terminal defined by R15/16 can be divided into the same number of receive antennas and transmit antennas (i.e., T = R), and more receive antennas than transmit antennas (i.e., R > T). In the related art, in the case of T = R supported by the current protocol, the terminal antenna switching capability mainly includes one-transmission one-reception (1T 1R), two-transmission two-reception (2T 2R), and four-transmission four-reception (4T 4R). The case of R > T, i.e. more receive than transmit antennas, is mainly several: one-transmission two-receiving (1T 2R), one-transmission four-receiving (1T 4R) and two-transmission four-receiving (2T 4R).

Wherein, the antenna switching capability supported by the terminal in R15 is: 1T2R,1T4R,2T4R,1T4R-2T4R,1T1R,2T2R,4T4R.

The antenna switching capability supported by the terminal in R16 is: 1T1R-1T2R,1T1R-1T2R-1T4R,1T1R-1T2R-2T2R-2T4R,1T1R-1T2R-2T2R-1T4R-2T4R,1T1R-2T2R,1T1R-2T2R-4T4R.

In the research of R17, the number of antennas of the terminal is considered to be required to be further increased, so that the number of antennas is further increased to 6 antennas or 8 antennas at the maximum. Typical antenna configurations as presently defined are {1T6R,1T8R,2T6R,2T8R, [4T6R ],4T8R } as shown in Table 1 below:

table 1: SRS antenna switching combination of up to 8 antennas

Tx\Rx	6Rx	8Rx
1T	1T6R	1T8R
2T	2T6R	2T8R
4T	4T6R	4T8R

Wherein, whether 4T6R supports the current pending, and then the subsequent high probability will support from the standard angle.

Different antenna switching configurations correspond to different Sounding Reference Signal resource configurations, main antenna switching configurations supported in the current protocol, and correspondingly, sounding Reference Signal (SRS) resource configurations are as follows:

(1) For a terminal with the same number of transmit/receive antennas (T = R), the network device may configure at most two SRS resource sets, where only one SRS resource in one set has a port number equal to the number of transmit antennas of the terminal. One of the two sets of SRS resources may be configured to be periodic and the other may be configured to be aperiodic.

(2) For a terminal with a single-sending and two-receiving (1T 2R) capability, a network device may configure at most two SRS resource sets, where there are two SRS resources in one set and each SRS resource has only one port.

(3) For a terminal with two-transmission-four-reception (2T 4R) capability, a network device may configure at most two SRS resource sets, where there are two SRS resources in one set and each SRS resource has two ports.

(4) For a terminal with one-transmitting four-receiving (1T 4R) capability, network equipment needs special consideration for configuring SRS resources, and only one resource set can be configured for periodic or semi-continuous SRS resources at most, wherein 4 SRS resources respectively have 1 port; at most 2 SRS resource sets can be configured for the aperiodic SRS resource, and a total of 4 SRS resources are available in two SRS resource sets, and the 4 resources are transmitted in two slots and the 4 resources are transmitted by different physical antennas. Two resource sets can be configured with 2 resources each, or one set 1 and the other set 3 resources, each resource having only 1 port.

In a 5G NR system, triggering of SRS resources may include a periodic/semi-persistent/aperiodic SRS resource configuration triggering mechanism.

All parameters of the periodic SRS (P-SRS) are configured by a high-level signaling, and the terminal periodically transmits the parameters after the parameters are configured by the high-level signaling. All parameters of the semi-persistent SRS (SP-SRS) are also configured by higher layer signaling, which is different from the periodic Sounding Reference Signal (SRS) in that although the corresponding parameters have been configured, the terminal cannot transmit the Sounding Reference Signal (SRS) until receiving the activation command. Once the activated terminal starts to transmit Sounding Reference Signals (SRS) until a deactivation command sent by the network side is received. The activation and deactivation command of the semi-persistent Sounding Reference Signal (SRS) is transmitted by the MAC layer, i.e., the MAC CE command.

The aperiodic SRS resource (AP-SRS) triggering is triggered by an SRS request in a Downlink Control Information (DCI), and table 2 is a specific triggering signaling.

TABLE 2

In the related art, the uplink SRS may be a periodic SRS, a semi-persistent SRS, or an aperiodic SRS. Narrowband or wideband, single or multiport. The uplink SRS parameter may be configured to the terminal by the network, and includes the number of ports, the frequency domain resource location, the time domain resource location, the sequence cyclic offset, and the like. In the 5G NR system, SRS is mapped on six symbols at most in one uplink slot, as shown in fig. 3, which shows an SRS mapping region within a slot.

The network device may configure a plurality of uplink SRS sets for the terminal, where one resource set includes one or more SRS resources. One SRS resource may be on N consecutive OFDM symbols, and N may occupy 1,2,4 symbols.

The gNB side is supported in the R15/16NR system to acquire the downlink channel information through channel reciprocity so as to improve the downlink data transmission performance. In order to support that the gNB can also effectively acquire downlink information through channel reciprocity under various terminal transceiving capabilities, the NR system particularly designs an SRS reference signal.

Further, in order to adapt to the current service or scenario, the terminal may need to change the antenna configuration, for example, from 2T4R to 1T4R or 2T2R, or from 2T2R to 4T4R, and then needs to switch the antenna switching configuration.

If some antennas of the current terminal are in other Radio Access Technology (RAT) reception, or the gain of some antennas in the current frequency band is low, or the terminal currently has a power saving requirement, or the antenna configuration needs to be changed from the terminal service transmission perspective.

The current antenna configuration is per BWP, and can be implemented by Radio Resource Control (RRC) reconfiguration or BWP handover, but this handover is mainly implemented by rescheduling at the network side through service change, and cannot be triggered according to the situation at other terminal sides, so that the network cannot meet the handover requirement at the UE side, and cannot adapt to the terminal and service requirements more quickly and flexibly to support the handover or fallback of the antenna configuration. The current mechanism also cannot provide better measurement reporting support for the fast and dynamic switching antenna switching configuration method on BWP.

In view of this, an embodiment of the present disclosure provides a method for switching antenna switching configuration, where a terminal reports antenna switching configuration requirement information according to network configuration, and indicates, by the antenna switching configuration requirement information, antenna switching configuration information that the terminal desires to use. The network equipment receives the antenna switching configuration requirement information sent by the terminal, and assists in switching the antenna switching configuration based on the antenna switching configuration requirement information. Therefore, according to the switching method for antenna switching configuration provided by the embodiment of the present disclosure, the network device can accurately and quickly implement switching of antenna switching configuration based on the requirement of the terminal, and assist the terminal in switching of antenna switching configuration, so as to save the transmission power or the reception power, and enable system resources to be optimally used.

Fig. 4 is a flowchart illustrating a method for switching an antenna switching configuration according to an exemplary embodiment, where the method for switching an antenna switching configuration is used in a terminal, as shown in fig. 4, and includes the following steps.

In step S11, in response to determining that the antenna switching configuration needs to be switched, reporting antenna switching configuration requirement information according to the network configuration.

In the embodiment of the present disclosure, the antenna switching configuration requirement information is used to indicate the antenna switching configuration information that the terminal desires to use.

In the embodiment of the present disclosure, the terminal is provided with at least two candidate antenna switching configurations, and is capable of determining one candidate antenna switching configuration from the at least two candidate antenna switching configurations or switching from one candidate antenna switching configuration to another candidate antenna switching configuration.

In the method for switching the antenna switching configuration provided by the embodiment of the disclosure, the terminal may support multiple antenna switching configurations, for example, 1t1r _2t2r _4t4r. The terminal may perform a switch of the antenna switching configuration. The network device may switch the antenna switching configuration to a certain antenna switching configuration at the current BWP. The terminal may determine, through measurement or event trigger, that the antenna switching configuration needs to be switched, that is, it is desirable to change the antenna switching configuration. And responding to the switching of the antenna switching configuration determined by the terminal, and reporting antenna switching configuration requirement information according to the network configuration, wherein the antenna switching configuration requirement information is used for indicating the antenna switching configuration information expected to be used by the terminal. Therefore, the switching method for antenna switching configuration provided by the embodiment of the disclosure can accurately and quickly realize switching of antenna switching configuration based on the requirement of the terminal, and can save the transmission power or the reception power, so that the system resource can be optimally used.

In the method for switching antenna switching configuration provided in the embodiment of the present disclosure, the information of the requirement for antenna switching configuration may sometimes be understood as a suggested value that is reported when the terminal desires to change the antenna switching configuration, or may also be understood as a reported quantity that is reported when the terminal desires to change the antenna switching configuration.

The high layer number or the predefined number 0 corresponding to 1T1R, the number 1 corresponding to 1T2R, the number 2 corresponding to 2T2R, when the terminal reports 1, the terminal is expected to select to configure 1T2R, or the terminal reports the corresponding bitmap, if 010 configures 1T2R.
