[0038] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several terminals 11 and several access devices 12.

[0039] Terminal 11 may refer to a device that provides voice and / or data connectivity to a user. Terminal 11 may communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, the terminal may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user device, user agent, user equipment (UE), or user terminal. Alternatively, terminal 11 may be a device on an unmanned aerial vehicle. Alternatively, terminal 11 may be an in-vehicle device, such as a vehicle-mounted computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle-mounted computer. Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

[0040] The access device 12 may be a network node device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as a new generation radio access network (NG-RAN). Alternatively, an MTC system.

[0041] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0042] A wireless connection can be established between the access device 12 and the terminal 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0043] Optionally, the above-mentioned wireless communication system may further include a network management device 13. Several access devices 12 are respectively connected to the network management device 13. The network management device 13 may be a core network device in the wireless communication system. For example, the network management device 13 may be a mobility management entity (MME) in the evolved packet core (EPC). Alternatively, the network management device may also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF) or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 13.

[0044] Exemplarily, the terminal 11 may be a UE in the embodiments of the present disclosure. For example, a UE may include, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensor device, and / or a medical device. The access device 12 may be a network device in the embodiments of the present disclosure, such as a base station.

[0045] like Figure 2 As shown, an embodiment of the present disclosure provides a communication control method, which is executed by a UE, and the method includes:

[0046] S110: Participate in DMRS bundling and perform antenna switching based on the first information indicated by the network device.

[0047] In the embodiments of the present disclosure, the network device may be a base station, etc., and the DMRS bundling process may be performed by the base station. For example, the base station implements joint demodulation by performing DMRS bundling, and the UE participates in DMRS bundling, which means that the UE assists the base station in implementing joint demodulation, and the UE maintains phase continuity and power consistency during the DMRS bundling process. For example, the UE maintains phase continuity and power consistency in an actual time domain window (TDW) during the DMRS bundling process.

[0048] In some implementations, participating in DMRS bundling and performing antenna switching may include: during an uplink channel repetition (PUSCH repetition), the UE maintains phase continuity and power consistency during a TDW process, and performing antenna switching during the uplink channel repetition process.

[0049] In one embodiment, antenna switching can be the switching of physical antennas or the switching of antenna ports. For example, in the repeated transmission of the uplink channel, if the channel sounding reference signal (Sounding Reference Signal, SRS) resource set (resource set) or SRS resource (resource) bound to the uplink channel is different, it means that antenna switching is performed during the repeated transmission of the uplink channel.

[0050] In one embodiment, the first information indicated by the network device may include DMRS bundling configuration information, or may also include other information such as a first TDW indicated to the UE, a TDW length threshold, etc. The first TDW may be a nominal TDW, and information such as the nominal TDW and / or the TDW length threshold may be included in the DMRS bundling configuration information, or may be separately indicated by the network device to the UE from the DMRS bundling configuration information.

[0051] In one embodiment, the first TDW indicated by the network device may include a first TDW length indicated by the network device. The first TDW length may be indicated by a length value, or by a start time and an end time of the first TDW. For example, the DMRS bundling configuration information may include the first TDW length value and / or the start time and the end time of the first TDW. The UE may then determine the first TDW length based on this information in the DMRS bundling configuration information.

[0052] In one embodiment, participating in DMRS bundling and performing antenna switching may be applied during multiple uplink transmissions, wherein the multiple uplink transmissions are applied to at least one of a dynamic grant PUSCH, a configured grant PUSCH, or a Physical Uplink Control Channel (PUCCH).

[0053] In one embodiment, uplink multiple transmissions may include: PUSCH transmissions of PUSCH repetition Type A scheduled by DCI format 0_1 ​​or 0_2, PUSCH transmissions of PUSCH repetition Type A with a configured grant, PUSCH transmissions of PUSCH repetition Type B, PUSCH transmissions of TB processing over multiple slots (TBoMS), and PUCCH transmissions of PUCCH repetition, etc. DCI in DCI format 0_1 ​​may be referred to as DCI format 0_1.

[0054] In one embodiment, since the UE needs to maintain power consistency and / or phase continuity during DMRS binding, participating in DMRS binding and performing antenna switching may be performed in different time units for DMRS binding and antenna switching. The time unit may be a time slot or a symbol, etc. Exemplarily, participating in DMRS binding and performing antenna switching may be performed alternately during multiple uplink transmissions. For example, during the DMRS binding process, the UE participates in DMRS binding in time slots 1-8, performs antenna switching in time slot 9, participates in DMRS binding in time slots 10-17, etc. In this way, during the DMRS binding process, DMRS binding and antenna switching are not performed at the same time, thereby reducing the impact of antenna switching on DMRS binding due to the destruction of UE phase consistency on the basis of improving channel coverage through antenna switching combined with DMRS binding, thereby improving communication stability.

[0055] In one embodiment, when the first condition is not met, both DMRS bundling and antenna switching are not performed during the uplink multiple transmission processes. For example, the UE may only participate in the DMRS bundling process without performing antenna switching.

[0056] In one embodiment, when the base station performs DMRS bundling, the UE maintains power consistency and phase continuity.

[0057] In one embodiment, the first information may include DMRS binding configuration information. The DMRS binding configuration information may be used to configure relevant information of the UE in participating in DMRS binding, and may also be used to determine the first condition that must be met for participating in DMRS binding and performing antenna switching during multiple uplink transmissions of the UE. For example, the DMRS binding configuration information may carry or indicate the first condition, or may also carry or indicate information corresponding to the first condition. The DMRS binding configuration information may be configured separately for different uplink channels.

[0058] In one embodiment, the first target field in the DMRS bundling configuration information may be used to indicate participation in DMRS bundling and antenna switching. For example, the first target field may be "pusch-antenna switching," and the value corresponding to the first target field may be "enable" or "disable."

[0059] In one embodiment, the first condition may be that the value corresponding to the first target domain is a target value, for example, the value corresponding to the first target domain is "enable." Therefore, when the first condition is met, that is, when the value corresponding to the first target domain in the DMRS bundling configuration information is determined to be the target value, the UE participates in DMRS bundling and performs antenna switching.

[0060] In one embodiment, the first information may include a first TDW, such as the length of the first TDW. The first TDW may be a nominal TDW, which may be determined by the base station based on the UE's capabilities and indicated to the UE. The UE maintains power consistency and phase continuity within the first TDW. In actual implementation, the UE may determine the length of the actual TDW based on system configuration or other events, and maintain power consistency and phase continuity within the actual TDW. Ideally, that is, when no events occur, the nominal TDW length is equal to the actual TDW length.

[0061] In one embodiment, the first TDW indicated by the network device may be a first TDW configured, triggered, or activated by the network device. Accordingly, the first condition may be that the length of the first TDW is less than or equal to a TDW length threshold. Therefore, when the first condition is met, i.e., when the length of the nominal TDW is determined to be less than or equal to the TDW length threshold, the UE participates in DMRS bundling and performs antenna switching.

[0062] In one embodiment, the TDW length threshold may be determined according to a standard predefined rule, or may be indicated by a network device, for example, by receiving the TDW length threshold indicated by the network device through Radio Resource Control (RRC) signaling.

[0063] In one embodiment, the first information may also include: DMRS binding configuration information, wherein the DMRS binding configuration information may carry a TDW length threshold, or the second target domain in the DMRS binding configuration information may indicate a TDW length threshold, for example, the second target domain may be "pusch-TimeDomainWindowLengthThreshold".

[0064] Exemplarily, the value corresponding to the second target domain in the DMRS binding configuration information can be a TDW length threshold, such as 10ms, etc., or the TDW length threshold can be determined based on the value corresponding to the second target domain. For example, the value corresponding to the second target domain can indicate the number of time slots, such as 8, 10 or 15, etc., or it can be determined as a TDW length threshold based on the value corresponding to the second target domain and a predetermined ratio.

[0065] In this way, when the nominal TDW length is less than or equal to the TDW length threshold, that is, when the nominal TDW length is small, it is possible to participate in DMRS binding and perform antenna switching. Since DMRS binding and antenna switching are performed in different time slots, when the nominal TDW length where DMRS binding is performed is small, for example, antenna switching can be performed between two nominal TDWs, then the frequency of antenna switching can be higher, thereby better improving channel coverage.

[0066] In one embodiment, when the first condition is not met, that is, the nominal TDW length is greater than the TDW length threshold, the scheme of participating in DMRS binding and performing antenna switching may not be executed. For example, only participating in the DMRS binding process and not performing antenna switching. In this way, it can be considered that DMRS binding can be performed by using a sufficiently large TDW length to meet the coverage requirements of the uplink channel.

[0067] In one embodiment, the first information indicated by the network device includes a first TDW length and DMRS bundling configuration information, wherein the first TDW length and the DMRS bundling configuration information may be sent by the network device simultaneously, or may be sent separately to the UE.

[0068] In one embodiment, the DMRS binding configuration information may include a first target domain and a second target domain. The first target domain may indicate whether to support participation in DMRS binding and perform antenna switching. For example, when the value of the first target domain is the target value, the UE determines that it can support participation in DMRS binding and perform antenna switching. Further, the second target domain may indicate participation in DMRS binding and perform antenna switching after the first condition is met. For example, when the first TDW length is less than or equal to the TDW length threshold determined by the value corresponding to the second target domain, participate in DMRS binding and perform antenna switching.

[0069] In one embodiment, performing antenna switching includes performing antenna switching based on an antenna switching time interval.

[0070] In one embodiment, when antenna switching intervals are enabled, for PUSCH repetition type A, a first SRS resource set is associated with N time slots in a first time interval, and a second SRS resource set is associated with N time slots in a second time interval. The same SRS resource set mapping pattern continues to the remaining time slots in K consecutive time slots, where K is the repetition transmission factor and N is the number of antenna switching intervals.

[0071] In one embodiment, when antenna switching intervals are enabled, for PUSCH repetition type B, the first SRS resource set is associated with the first set of N nominal repetition transmissions, and the second SRS resource set is associated with the second set of N nominal repetition transmissions. The same SRS resource set mapping pattern continues for the remaining nominal repetition transmissions in the K repetitions, where K is the repetition transmission factor and N is the nominal number of repetition transmission intervals for antenna switching.

[0072] In one embodiment, when antenna switching intervals are enabled, for PUSCH repetition type B, the first SRS resource set is associated with actual repetition transmissions within the first group of N time slots, and the second SRS resource set is associated with actual repetition transmissions within the second group of N time slots. The same SRS resource set mapping pattern continues for the remaining actual repetition transmissions in the K repetitions, where K is the repetition coefficient and N is the number of antenna switching intervals.

[0073] In one embodiment, when the first information includes DMRS bundling configuration information, the antenna switching time interval may be determined according to the DMRS bundling configuration information. For example, the method may further include: determining whether a third target domain exists in the DMRS bundling configuration information.

[0074] Among them, the time interval for antenna switching is determined based on the value corresponding to the third target domain; the first information includes DMRS binding configuration information, and the third target domain exists in the DMRS binding configuration information; or, the length of the first TDW indicated by the network device or the length of the second TDW determined by the UE is determined as the time interval for antenna switching.

[0075] Here, the second TDW determined by the UE may be an actual TDW determined by the UE. The actual TDW may be determined by the UE based on the first TDW, for example, by adjusting the first TDW based on an event during transmission. Accordingly, the UE's participation in DMRS bundling may include maintaining power consistency and phase continuity within the second TDW corresponding to the DMRS bundling.

[0076] In one embodiment, the value corresponding to the third target field indicates the number of time units or the nominal number of repeated transmissions. For example, the value corresponding to the third target field may be the antenna switching time interval, such as 10ms or 20ms, or the value corresponding to the third target field may also indicate the number of time slots, such as indicating that the antenna switching time interval is 10 or 20 time slots; or the value corresponding to the third target field may also be the nominal number of repeated transmissions.

[0077] The nominal number of repeated transmissions is the number of repeated transmissions performed by the UE as instructed by the network device. The antenna switching time interval can be determined based on the nominal number of repeated transmissions. For example, every n nominal repeated transmissions corresponds to one time slot, where n is an integer greater than 1. For example, every eight nominal repeated transmissions corresponds to one time slot. Therefore, when the value corresponding to the third target field indicates that the nominal number of repeated transmissions is 16, the antenna switching time interval is determined to be two time slots, etc.

[0078] In one embodiment, the time interval for antenna switching may also be determined according to a predetermined rule. For example, the time interval for antenna switching may be determined according to the predetermined rule to be equal to the length of the first TDW.

[0079] In one embodiment, the first information may be carried in RRC signaling. For example, when the first information is DMRS bundling configuration information, the UE receives the first information indicated by the network device via RRC signaling. When the first information includes the first TDW and DMRS bundling configuration information, the first TDW and DMRS bundling configuration information may be carried in the same RRC signaling or in different RRC signaling.

[0080] In this way, through the instructions of the network equipment, the UE can participate in DMRS binding and perform antenna switching under certain conditions, thereby further improving the channel coverage in scenarios such as NTN through antenna switching, thereby improving communication stability, and more accurately determining the timing of initiating antenna switching during the DMRS binding process, thereby improving the flexibility and accuracy of communication mode adjustment.

[0081] In some embodiments, as Figure 3 As shown, step S110 may include:

[0082] S111: Based on the first information indicated by the network device, participate in DMRS bundling and perform antenna switching after a first condition is met.

[0083] In some embodiments, the first information includes: DMRS bundling configuration information;

[0084] like Figure 4 As shown, step S111 may include:

[0085] S112: Determine a value corresponding to the first target domain in the DMRS binding configuration information indicated by the network device;

[0086] S113: When the value corresponding to the first target domain is the target value, participate in DMRS binding and perform antenna switching.

[0087] In an embodiment of the present disclosure, the first target field may be "pusch-antenna switching," and the value of the first target field may be configured as a value in the form of, for example, "enable" or "disable," to indicate whether the UE participates in DMRS binding and performs antenna switching. When the UE determines that the value corresponding to the first target field is a target value, such as the target value of "enable," the UE participates in DMRS binding and performs antenna switching.

[0088] In one embodiment, the DMRS binding configuration information may further include a second target domain, wherein the first target domain may indicate whether participation in DMRS binding and antenna switching is supported, and the second target domain may indicate a first condition corresponding to participation in DMRS binding and antenna switching. For example, step S113 may include: when the value corresponding to the first target domain is the target value, after determining that the first condition is satisfied based on the second target domain in the DMRS binding configuration information, participating in DMRS binding and performing antenna switching.

[0089] Exemplarily, S113 may include: when the value corresponding to the first target domain is the target value, determining support for participating in DMRS binding and performing antenna switching; determining the TDW length threshold based on the value corresponding to the second target domain in the DMRS binding configuration information; when the length of the first TDW indicated by the network device is less than or equal to the TDW length threshold, participating in DMRS binding and performing antenna switching.

[0090] In one embodiment, participating in DMRS bundling and performing antenna switching includes: participating in DMRS bundling and performing antenna switching based on a time interval of antenna switching.

[0091] Among them, the time interval for antenna switching is determined based on the value corresponding to the third target domain; the first information includes DMRS binding configuration information, and the third target domain exists in the DMRS binding configuration information; or, the length of the first TDW indicated by the network device or the length of the second TDW determined by the UE is determined as the time interval for antenna switching.

[0092] In one embodiment, the method may further include: determining whether a third target domain exists in the DMRS bundling configuration information.

[0093] In one embodiment, the time interval for antenna switching may also be determined according to a predetermined rule. For example, the time interval for antenna switching is determined to be the length of the first TDW according to the predetermined rule.

[0094] In this way, when the UE receives the DMRS binding configuration information indicated by the network device, it can determine whether the network device indicates to participate in DMRS binding and perform antenna switching, thereby facilitating the UE to start quickly and improve channel coverage and efficiency. At the same time, by indicating through the DMRS binding configuration information, the issuance of separate RRC signaling can be reduced. When the first condition is not met, that is, when the first TDW length is greater than the TDW length threshold, the scheme of participating in DMRS binding and performing antenna switching may not be executed, for example, only participating in the DMRS binding process without performing antenna switching. In this way, it can be considered that DMRS binding with a sufficiently large TDW length can meet the coverage requirements of the uplink channel.

[0095] It should be noted that, for descriptions of contents that are repeated or corresponding to other embodiments, please refer to the relevant contents in the aforementioned embodiments such as step S110, and no further details will be given here.

[0096] In some embodiments, the first information includes: a first TDW;

[0097] like Figure 5 As shown, step S111 may include:

[0098] S114: Determine the TDW length threshold;

[0099] S115: When the length of the first TDW indicated by the network device is less than or equal to the TDW length threshold, participate in DMRS bundling and perform antenna switching.

[0100] In an embodiment of the present disclosure, the first TDW length can be indicated or configured to the UE by the network device, and the TDW length threshold can be indicated to the UE by the network device, for example, through the second target domain indication in the DMRS binding configuration information indicated by RRC signaling, or can also be determined by the UE based on predetermined rules, for example, according to standard predefined rules between the network device and the UE.

[0101] In one embodiment, the first information may further include DMRS bundling configuration information. Step S114 may include: determining a value corresponding to a first target field in the DMRS bundling configuration information indicated by the network device; and determining a TDW length threshold when the value corresponding to the first target field is a target value.

[0102] In one embodiment, determining the TDW length threshold may include: determining the TDW length threshold based on a predetermined rule; or, when the first information further includes DMRS binding configuration information, determining the TDW length threshold based on a value corresponding to the second target domain in the DMRS binding configuration information.

[0103] In one embodiment, performing antenna switching includes performing antenna switching based on an antenna switching time interval.

[0104] The antenna switching time interval is determined based on a value corresponding to the third target field; the first information includes DMRS bundling configuration information, and the third target field is present in the DMRS bundling configuration information; or the length of a first TDW indicated by the network device or a second TDW determined by the UE is determined as the antenna switching time interval. In one embodiment, the method may further include: determining whether the third target field is present in the DMRS bundling configuration information.

[0105] In one embodiment, the time interval for antenna switching may also be determined according to a predetermined rule. For example, the time interval for antenna switching is determined to be the length of the first TDW according to the predetermined rule.

[0106] In this way, when the first TDW length is less than or equal to the TDW length threshold, that is, when the nominal TDW length is small, DMRS binding can be participated in and antenna switching can be performed. Since DMRS binding and antenna switching are performed in different time slots, when the first TDW length where DMRS binding is performed is small, for example, antenna switching can be performed between two first TDWs, then the frequency of antenna switching can be higher, thereby better improving channel coverage.

[0107] In some embodiments, as Figure 6 As shown, the method further includes:

[0108] S116: Determine an antenna switching time interval based on a value corresponding to the third target domain; the first information includes DMRS bundling configuration information, and the DMRS bundling configuration information contains the third target domain;

[0109] S117: Determine the length of the nominal first TDW indicated by the network device or the length of the second TDW determined by the UE as the time interval for antenna switching;

[0110] Step S113 includes:
