The following description of exemplary embodiments is not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0139] The switching method of the antenna switching configuration provided by the embodiments of the present disclosure can be applied to Figure 1 the wireless communication system shown. SeeFigure 1 As shown in the figure, the wireless communication system includes network devices and terminals. The terminals are connected with the network devices through wireless resources and perform data transmission.

[0140] It can be understood that, Figure 1 The wireless communication system shown in the figure is only illustrative. The wireless communication system can further include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices, etc., which are not shown in the figure. The number of network devices and the number of terminals in the wireless communication system are not limited in the embodiments of the present disclosure. Figure 1

[0141] It can be further understood that the wireless communication system in the embodiments of the present disclosure is a network providing wireless communication function. The wireless communication system can use 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 (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA). According to different network capacities, rates, time delays, and other factors, the network can be divided into 2G (English: generation) network, 3G network, 4G network, or future evolution network, such as 5G network. The 5G network can also be referred to as new radio network (New Radio, NR). For the convenience of description, the wireless communication network is sometimes referred to as network in the present disclosure.

[0142] ​Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), etc., and can also be a gNB in an NR system, or can also be a component or a part of a device constituting a base station, etc. It should be understood that the specific technology and specific device form adopted by the network device in the embodiments of the present disclosure is not limited. In the present disclosure, the network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device.

[0143] Further, the terminal involved in the present disclosure can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity for a user, for example, a terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a mobile phone, a customer premise equipment (CPE), a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the terminal in the embodiments of the present disclosure is not limited.

[0144] In the related art, MIMO technology is used to improve data transmission rate, and to improve data throughput and signal-to-noise ratio. MIMO refers to using multiple transmit antennas and receive antennas at the transmit end and the receive end respectively, so that the signal is transmitted and received through multiple antennas at the transmit end and the receive end, to improve data throughput and signal-to-noise ratio, thereby improving system performance and improving communication quality. It can fully utilize space resources, and through multiple antennas, multiple transmission and multiple reception can be realized, and in the case of not increasing spectrum resources and antenna transmission power, the system channel capacity can be doubled.

[0145] MIMO technology is increasingly being applied to a variety of high data rate technologies, including WiFi, 4G Long Term Evolution (LTE) and 5G NR. MIMO system is the parallel transmission of multiple signal streams in the air. The input data stream at the transmitting end becomes several parallel symbol streams, which are transmitted simultaneously from Nt antennas; the receiving end receives the signals from Nr receiving antennas and restores the original signals, as shown in Figure 2 .

[0146] In order to support various terminal transceiver capabilities to effectively obtain downlink information through the channel, different antenna switching configurations are set for terminals in the communication system. The antenna switching capability of the terminal defined in R15 / 16 can be divided into the same number of receiving antennas and transmitting antennas (i.e., T = R) and more receiving antennas than transmitting antennas (i.e., R > T). In related technologies, the terminal antenna switching capability mainly includes one transmitting and one receiving (1T1R), two transmitting and two receiving (2T2R), and four transmitting and four receiving (4T4R) in the case of T = R supported by the current protocol. In the case of R > T, i.e., more receiving antennas than transmitting antennas, there are mainly several cases: one transmitting and two receiving (1T2R), one transmitting and four receiving (1T4R), and two transmitting and four receiving (2T4R).

[0147] Among them, the antenna switching capability supported by the terminal in R15 is: 1T2R, 1T4R, 2T4R, 1T4R-2T4R, 1T1R, 2T2R, 4T4R.

[0148] 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.

[0149] In the current research of R17, there is a demand for further increasing the number of antennas of the terminal, so the number of antennas will be further increased to a maximum of 6 antennas or a maximum of 8 antennas. The currently defined typical antenna configuration is {1T6R, 1T8R, 2T6R, 2T8R, [4T6R], 4T8R}, as shown in Table 1:

[0150] Table 1: SRS antenna switching combination up to 8 antennas

[0151] Tx\Rx 6Rx 8Rx 1T 1T6R 1T8R 2T 2T6R 2T8R 4T 4T6R 4T8R

[0152] Among them, whether 4T6R is supported is pending, and it is likely to be supported from the standard perspective in the future.

[0153] Different antenna switching configurations correspond to different sounding reference signal resource configurations. The main antenna switching configurations supported in the current protocol correspond to the following SRS resource configurations:

[0154] (1) For terminals with the same number of transmit and receive antennas (T = R), the network device can configure up to two SRS resource sets, with only one SRS resource in one set, and the number of ports in the SRS resource is equal to the number of transmit antennas of the terminal. One of the two SRS resource sets can be configured as periodic, and the other can be configured as aperiodic.

[0155] (2) For terminals with one transmit and two receive antennas (1T2R) capability, the network device can configure up to two SRS resource sets, with two SRS resources in one set, and each SRS resource having only one port.

[0156] (3) For terminals with two transmit and four receive antennas (2T4R) capability, the network device can configure up to two SRS resource sets, with two SRS resources in one set, and each SRS resource having two ports.

[0157] (4) For terminals with one transmit and four receive antennas (1T4R) capability, the network device needs to consider special SRS resource configurations. Periodic or semi-persistent SRS resources can only be configured with one resource set, with four SRS resources each having one port. For aperiodic SRS resources, up to two SRS resource sets can be configured, with a total of four SRS resources in the two SRS resource sets, and the four resources being transmitted in two slots and being transmitted by different physical antennas. Two resource sets can each be configured with two resources, or one set with one resource and the other set with three resources, each resource having only one port.

[0158] In the 5G NR system, the triggering of SRS resources can include periodic / semi-persistent / aperiodic SRS resource configuration triggering mechanisms.

[0159] Among them, the periodic SRS (P-SRS) all parameters are configured by high layer signaling, and the terminal transmits periodically according to the configured parameters after being configured by high layer signaling. The semi-persistent SRS (SP-SRS) all parameters are also configured by high layer signaling, and the difference from the periodic sounding reference signal (SRS) is that although the corresponding parameters have been configured, the terminal cannot transmit the sounding reference signal (SRS) before receiving the activation command. Once activated, the terminal starts transmitting the sounding reference signal (SRS) until receiving the deactivation command sent by the network side. The activation and deactivation commands of the semi-persistent sounding reference signal (SRS) are sent by the MAC layer, that is, the MAC CE command.

[0160] The aperiodic SRS resource (AP-SRS) is triggered by SRS request in downlink control information (DCI). Table 2 is the specific triggering signaling.

[0161] Table 2

[0162]

[0163] In the related art, the uplink SRS can be periodic, semi-persistent or aperiodic. It can be narrowband or wideband, single-port or multi-port. The uplink SRS parameters can be configured by the network to the terminal, including the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cyclic shift, etc. In the 5G NR system, the SRS is mapped on a maximum of six symbols of an uplink slot, as shown in FIG. 1. Figure 3 FIG. 1 shows the SRS mapping area in a slot.

[0164] The network device can configure multiple uplink SRS sets for the terminal, and one resource set contains one or more SRS resources. One SRS resource can occupy N consecutive OFDM symbols, and N can occupy 1, 2 or 4 symbols.

[0165] In the R15 / 16 NR system, the gNB side supports obtaining downlink channel information through channel reciprocity to improve the performance of downlink data transmission. In order to support the gNB to effectively obtain downlink information through channel reciprocity under various terminal transceiver capabilities, the NR system specially designs the SRS reference signal.

[0166] Further, in order to adapt to the current business or scene, the terminal may need to change the antenna configuration, for example, from 2T4R to 1T4R or 2T2R, or from 2T2R to 4T4R, at which time the antenna switching configuration needs to be switched.

[0167] If the current terminal has some antennas receiving other radio access technologies (RATs), or the gain of some antennas is low under the current frequency band, or the terminal currently has power saving needs, or from the perspective of terminal business transmission, it is also necessary to consider changing the antenna configuration.

[0168] The current antenna configuration is per BWP, which can be realized through radio resource control (RRC) reconfiguration or BWP switching. However, this switching is mainly realized through service change and re-scheduling by the network side, and cannot be triggered according to the conditions of other terminal sides. Therefore, the network cannot meet the switching requirements of the UE side, and cannot more quickly and flexibly adapt to the terminal and service requirements to support antenna configuration switching or fallback. The current mechanism also cannot provide better measurement reporting support for the fast dynamic switching antenna switching configuration method on the BWP.

[0169] Therefore, in the embodiments of the present disclosure, a switching method of antenna switching configuration is provided. The terminal reports antenna switching configuration requirement information according to network configuration, and indicates antenna switching configuration information expected to be used by the terminal through the antenna switching configuration requirement information.

Therefore, the switching method of the antenna switching configuration provided by the embodiments of the present disclosure can accurately and quickly realize the switching of the antenna switching configuration based on the demand of the terminal, and can save the transmission power or the reception power, so that the system resources can be used optimally.
