Obviously, the described embodiments are only some of the embodiments of the application, but not all of the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the application.

It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second" are usually a category, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "or" in the application means at least one of the connected objects. For example, the protection scope of "A or B" at least covers three schemes, namely, scheme one: including A and not including B; scheme two: including B and not including A; scheme three: including A and B. In addition, the terms "A and / or B", "at least one of A and B", "at least one of A or B" also at least cover the above three schemes, respectively. The character " / " generally represents that the objects before and after are in an "or" relationship.

[0050] The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). The direct indication can be understood as that the sender explicitly informs the receiver of specific information, operations to be performed or requested results, etc. in the sent indication. The indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or the requested results according to the judgment result.

[0051] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems.

[0052] The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than the NR system, such as 6th Generation (6G) communication systems. th

[0053] In order to facilitate understanding of the embodiments of the present application, the following technical points are introduced first:

[0054] I. About Carrier Aggregation (CA)

[0055] To support wider transmission bandwidth, two or more component carriers are aggregated together to obtain higher peak rate and throughput.

[0056] In order to more efficiently use the fragmented spectrum, carrier aggregation supports aggregation between different carrier units:​

[0057] A) Intra-band contiguous CA (intra-band contiguous CA);

[0058] B) Intra-band non-contiguous CA (intra-band non-contiguous CA);

[0059] C) Inter-band CA (inter-band CA).

[0060] The schematic diagram of the above-mentioned types of carrier aggregation is shown in FIG. 1.

[0061] II. Multiple Input Multiple Output (MIMO).

[0062] A MIMO system uses multiple antennas (or array antennas) and multiple channels at the transmitting end and the receiving end. The MIMO technology can improve the capacity of a channel and the reliability of a channel, and reduce the bit error rate. The former is the spatial multiplexing gain (referred to as spatial multiplexing) provided by a MIMO channel, and the latter is the spatial diversity gain (referred to as transmit diversity) provided by a MIMO channel. For spatial multiplexing, the number of layers of antennas is defined as the rank of a MIMO channel matrix, that is, the number of independent virtual channels. For example, for a 4-transmit 2-receive antenna system, the number of layers of antennas can be 1 or 2 under different channel environments, and the maximum number of layers of antennas will not exceed the minimum value of the number of antennas at the transmitting end and the receiving end (here, 2).

[0063] III. FreqSeparationClass.

[0064] FreqSeparationClass is a signaling related to intra-band non-contiguous CA, which is used to indicate the frequency separation width between the lowest frequency carrier and the highest frequency carrier in a frequency band, and contains several levels, and different levels represent different frequency separation widths.

[0065] IV. Fragmented carriers and "interference signals or blockers".

[0066] A certain frequency band is allocated to several operators, and the spectrum allocated to the same operator can not be continuous all the time, but fragmented. If an operator wants to aggregate several fragmented frequency bands at the same time, it currently needs to use a receiving chain for each part.

[0067] Example 1, fragmentation of FR1 low bands in Australia, the same fill represents the same operator's spectrum access, and each frequency band block width is 5MHz. The spectrum of n26 and n5 bands in Australia is currently allocated to two operators: Telstra and TPG Telecom.

[0068] As shown in FIG. 2, in the in-band non-contiguous carrier aggregation CA_n26 (2A) of Telstra's regional network, CC1 and CC2 are the carriers participating in aggregation, and the carrier of TPG Telecom in the middle can be defined as a "blocker". Among them, Metro: "metro network" refers to the network within the metropolitan area, usually used to connect different locations within the city, providing high-speed data transmission and communication services. Regional: "regional network" refers to the network connecting the entire region, usually used to span cities, villages and other geographical locations, providing more extensive communication coverage and connection.

[0069] Example 2, fragmentation of FR1 mid bands in Canada, the same color depth fill represents the same operator's spectrum access, and each frequency band block width is 5MHz. As shown in FIG. 3, AWS: Advanced Wireless Services (Advanced Wireless Services), PCS: Personal Communications Service (Personal Communications Service), BRS: Broadband Radio Service (Broadband Radio Service), refers to the spectrum used to provide broadband wireless communication services.

[0070] Five, about the receiving link comparison.

[0071] Taking FIG. 4 as an example, the existing in-band non-contiguous carrier aggregation receiving link is a link that only receives one CC. Assuming that there are a total of 6 receiving links, then the number of CCs that can be aggregated is limited, i.e. at most 6 CCs can participate in aggregation.

[0072] In a carrier aggregation (CA) scenario, a New Radio (NR) data receiving rate is limited by the number of supported carriers, which is limited by the number of terminal receiving chains (Rx chains) and the capability of the terminal and the baseband processor capability in the terminal. The fragmented spectrum allocation in the same frequency band requires that each carrier independently uses a receiving chain for receiving when aggregating non-continuous carriers, which makes the operator unable to fully utilize its fragmented spectrum in the CA combination, thereby limiting the CA capability and the upper limit of the number of carriers that can be aggregated.

The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0077] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices together, and the embodiments of the present application do not make a specific limitation hereon. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a special hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0078] Taking the above Fig. 4 as an example, if part of the CCs can be shared by a link, for example, at most two adjacent CCs share one RX chain, then the number of links can be reduced to 3-6, and more CCs can be aggregated, and further the transmission rate can be improved.

[0079] In view of this, the embodiments of the present application provide a communication processing method, device and equipment to solve the problem of wasting link resources in the related art.

[0080] Referring to Fig. 6, the embodiments of the present application provide a communication processing method, and the specific steps include:

[0081] Step 61: The terminal communicates through a first link architecture; wherein the first link architecture refers to that part or all of the carriers of carrier aggregation use a shared receiving link.

[0083] Optionally, the above terminal supports a capability of supporting a shared receiving link.

[0084] Optionally, the above carrier can also be replaced by a subcarrier, for example, part or all of the carriers of carrier aggregation using a shared receiving link can also be described as part or all of the subcarriers participating in carrier aggregation using a shared receiving link.

[0085] In an embodiment of the present application, before the terminal communicates through the first link architecture, the method further includes:

[0086] The terminal communicates through a second link architecture; wherein the second link architecture refers to that each carrier of carrier aggregation uses an independent receiving link.

[0087] It can be understood that the second link architecture can also be referred to as a separate receiving link (separate RX chain) architecture or state.

[0088] For example, the terminal communicates by default using the second link architecture, and then the terminal can switch to communicate using the first link architecture.

[0089] In an embodiment of the present application, the communication performance under the first link architecture is represented by a first receiving index, and the communication performance under the second link architecture is represented by a second receiving index, wherein the first receiving index is the same as or different from the second receiving index.

[0099] The terminal receives the first carrier aggregation configuration sent by the network side device, and the terminal communicates through the second link architecture, wherein the first carrier aggregation configuration corresponds to the receiving index of the second link architecture.

[0206] The optional embodiments of the present application are described below in conjunction with Embodiments 1 to 16.

[0207] Embodiment 1

[0208] In this embodiment, the relative power between the carrier participating in aggregation and the blocker satisfies the first condition by default. The UE supports the capability of shared receive chain (share RX chain) and reports all supported frequency band combination information for carrier aggregation. The reported frequency band combination information can be associated with the receive index. Part of the frequency band combination information can be supported only when the shared RX chain is used, and corresponds to a set of relaxed receive indexes (first receive index). The network side device judges the receive index and combines other information such as the interference condition of the environment to perform carrier aggregation configuration indication. When the carrier aggregation configuration is indicated, the UE needs to switch to the shared RX chain to support it.

[0209] Referring to FIG. 8, the specific steps include:

[0210] Step 1: The UE supports the capability of shared receive chain (share RX chain) and reports all supported frequency band combination information for carrier aggregation.

[0211] Part of the frequency band combination information can be supported only when the shared RX chain is used, and is associated with a set of relaxed receive indexes.

[0212] Step 2: The network side device allocates a third carrier aggregation configuration or a fourth carrier aggregation configuration to the UE;

[0213] For example, the network side device can make a comprehensive judgment in combination with the reception index and other information, and allocate a third carrier aggregation configuration or a fourth carrier aggregation configuration to the UE.

[0214] Step 3a: According to the allocated fourth CA configuration, the UE obtains that it can use a separate reception link architecture, and the corresponding reception index is a set of more stringent reception indexes, i.e., the second reception index.

[0215] Step 3b: According to the allocated third CA configuration, the UE obtains that it must use a shared reception link architecture, and the corresponding reception index is a set of more relaxed reception indexes, i.e., the first reception index.

[0216] Embodiment Two

[0217] In this embodiment, the relative power between the carrier participating in aggregation and the blocker does not always satisfy the first condition, and needs to be detected and judged. When the first condition is satisfied, the reception link of the UE can be switched to the shared RX chain, and this operation can be performed by the UE itself. When the first condition is no longer satisfied, the reception link of the UE is switched back to the separate RX chain.

[0218] Referring to FIG. 9, the specific steps include:

[0219] Step 1: The UE reports all supported CA configuration combinations of the share RX chain capability.

[0220] Step 2: The network selects a configuration for the UE from the supported CA configurations. The network indicates to the UE the information of the first signal (blocker) between each carrier in each frequency band corresponding to the CA configuration.

[0221] Step 3: The UE detects the power of the blocker and judges the power size relationship between the blocker and the carrier participating in aggregation.

[0222] The above carrier is the carrier adjacent to the blocker, including the first carrier and the second carrier.

[0223] Step 4a: The power size relationship satisfies the third condition;

[0224] Optionally, the power relationship size satisfying the third condition includes at least one of the following: 1) the power of the first signal is not higher than a second value compared with the power of the first carrier or the second carrier; 2) the power spectral density of the first signal is not higher than a third value compared with the power spectral density of the first carrier or the second carrier.

[0225] Step 5a: UE switches to shared RX chain by itself, and the reception index is relaxed to a certain level; then step 6 is performed;

[0226] It can be understood that the UE switches to shared RX chain by itself, and the reception index is relaxed to a certain level, which means that the UE uses the first link architecture, and the UE uses the first reception index.

[0227] Step 4b: the power size relationship does not satisfy the third condition;

[0228] Step 5b: the UE maintains the separate reception chain link (separate RX chain) state unchanged;

[0229] That is, the UE uses the second link architecture;

[0230] Step 6: If the power size relationship no longer satisfies the third condition

[0231] Step 7: The UE returns to a CC independent use state in whole or in part, and the reception index is changed accordingly.

[0232] That is, the UE uses the second link architecture, and uses the second reception index.

[0233] Embodiment three

[0234] In this embodiment, the relative power between the carrier and the blocker does not always satisfy the third condition, and the UE needs to detect and judge.

[0235] Compared with embodiment two, the UE can aggregate more carriers after switching to shared RX chain, and correspondingly support more CA configurations.

[0236] At this time, the UE reports all CA configurations, and is divided into two categories, namely the second link architecture that the UE can support by default and the first link architecture that the UE can support after switching to shared RX chain.

[0237] When the first condition is satisfied, the reception link of the UE can be switched to shared RX chain, which can be performed by the UE itself. When the first condition is no longer satisfied, the UE reports the corresponding information (i.e., the first information) to the network side device, the network indicates the new CA configuration (i.e., the first carrier aggregation configuration) to the UE and switches the reception link back to the independent state.

[0238] In one embodiment, the network indicates the information of the first signal (blocker) between the carriers in each frequency band corresponding to the CA configuration to the UE, and the UE can only judge the link sharing possibility for the carriers that have been allocated.

[0239] Referring to FIG. 10, the specific steps include:

[0240] Step 1: UE reports its supported CA configuration combinations, including the default supported CA configuration and the CA configuration supported after switching to shared RX chain.

[0241] Step 2: Network selects the CA configuration (i.e., fourth carrier aggregation configuration) for UE from the default supported CA configuration, and indicates the blocker information between each carrier in each frequency band corresponding to the CA configuration to UE.

[0242] Step 3: UE detects the power of the first signal (blocker), judges the power size relationship between the carriers participating in aggregation, and then executes Step 4a or Step 5b.

[0243] Step 4a: If the power size relationship meets the third condition, then Step 5a is executed.

[0244] Step 5a: UE switches to shared RX chain by itself, and the reception index is relaxed to a certain level; then Step 6 is executed.

[0245] It can be understood that UE switches to shared RX chain by itself, and the reception index is relaxed to a certain level means that UE uses the first link architecture, and the UE uses the first reception index.

[0246] Step 4b: If the power size relationship does not meet the third condition, then Step 5b is executed.

[0247] Step 5b: UE maintains the separate RX chain state unchanged, i.e., UE continues to use the second link architecture, and the CA configuration does not change.

[0248] Step 6: UE reports to the network side which frequency band's reception link is switched to shared RX chain.

[0249] Step 7: Network issues a new CA configuration (i.e., second carrier aggregation configuration) to indicate that UE can aggregate more CCs.

[0250] Step 8: If the power size relationship no longer meets the third condition.

[0251] Step 9: UE reports relevant information (i.e., first information) to the network side.

[0252] Step 10: The network issues a new CA configuration, instructs the UE to use the new CA configuration, and all or part of the receiving link returns to a CC independent use state. The receiving index has a corresponding change.

[0253] That is, the UE uses the second link architecture and the second receiving index based on the new CA configuration (such as the first carrier aggregation configuration) issued by the network.

[0254] In another embodiment, the network indicates to the UE the blocker category one information between the carriers in each frequency band corresponding to the CA configuration. The network indicates to the UE the blocker category two information between the configured carriers and the unconfigured carriers in the frequency band. Compared with the embodiment shown in FIG. 6, in the embodiment shown in FIG. 7, the UE can also detect whether the unconfigured carrier can share the RX link of the configured carrier.

[0255] Referring to FIG. 11, the specific steps include:

[0256] Step 1: The UE supports the capability of shareRXchain, and reports all CA configuration combinations supported by the UE. One type is default support, and one type is supportable only after switching to shared RX chain. Step 2: The network selects the configuration for the UE from the default support CA configuration. The network indicates to the UE the blocker category one information between the carriers in each frequency band corresponding to the CA configuration. The network indicates to the UE the blocker category two information between the configured carriers and the unconfigured carriers in the frequency band.

[0257] Step 3: The UE detects the power of the blocker category one, judges the power size relationship one between the carriers participating in aggregation. The UE detects the power of the blocker category two, judges the power size relationship two between the unconfigured carriers and the configured carriers. Step 4a or step 4b or step 4c is executed.

[0258] Step 4a: Only the power size relationship one satisfies the third condition;

[0259] Step 5a: The UE switches to shared RX chain by itself, and the receiving index is relaxed to a certain level.

[0260] It can be understood that the UE switches to shared RX chain by itself, and the receiving index is relaxed to a certain level, which means that the UE uses the first link architecture, and the UE uses the first receiving index.

[0261] Step 6a: The UE reports to the network side which frequency band of the receiving link is switched to shared RX chain.

[0262] Step 7a: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0263] Step 4b: Both the first power size relationship and the second power size relationship satisfy the third condition;

[0264] Step 5b: The UE switches to a shared RX chain by itself, and the reception index is relaxed to a certain level;

[0265] Step 6b: The UE reports to the network side which frequency band has switched to a shared RX chain, and also reports to the network which unconfigured CCs can share the existing RX chain.

[0266] Step 7b: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0267] Step 4c: Neither the first power size relationship nor the second power size relationship satisfies the third condition;

[0268] Step 5c: The UE maintains the separate RX chain state unchanged, and the CA configuration is unchanged.

[0269] It can be understood that the UE maintaining the separate RX chain state unchanged means that the UE continues to use the second link architecture.

[0270] Step 8: If a certain power size relationship no longer satisfies the third condition;

[0271] Step 9: The UE reports relevant information (i.e., first information) to the network side;

[0272] Step 10: The network issues a new CA configuration, indicating that the UE uses the new CA configuration, and the reception link is returned to a CC independent use state in whole or in part. The reception index is changed accordingly.

[0273] That is, the UE uses the second link architecture and the second reception index based on the new CA configuration (such as the first carrier aggregation configuration) issued by the network.

[0274] In yet another embodiment, the network indicates to the UE information of blocker category one among carriers within each band corresponding to the CA configuration. The network indicates to the UE information of blocker category two between the configured CCs and the unconfigured carriers of the band. The network indicates to the UE information of blocker category three among the unconfigured carriers of the band. Compared to the embodiment shown in FIG. 11, in the embodiment shown in FIG. 8, the UE can further detect whether the unconfigured carriers can be link shared.

[0275] Referring to FIG. 12, the specific steps include:

[0276] Step 1: The UE reports its supported CA configuration combinations with the capability of supporting share RX chain. One is supported by default, and the other is supported by switching to shared RX chain.

[0277] Step 2: The network selects the configuration for the UE from the CA configurations supported by default.

[0278] The network indicates to the UE information of blocker category one among carriers within each band corresponding to the CA configuration. The network indicates to the UE information of blocker category two between the configured CCs and the unconfigured carriers of the band. The network indicates to the UE information of blocker category three among the unconfigured carriers of the band.

[0279] Step 3: The UE detects the power of blocker category one and judges the power size relationship one between the configured carriers. The UE detects the power of blocker category two and judges the power size relationship two between the unconfigured carriers and the configured carriers. The UE detects the power of blocker category three and judges the power size relationship three between the unconfigured carriers. Step 4a or step 4b or step 4c or step 4d or step 4e or step 4f is executed.

[0280] Step 4a: Only the power size relationship one satisfies the third condition.

[0281] Step 5a: The UE switches to shared RX chain by itself, and the reception index is relaxed to a certain level

[0282] That is, the UE uses the first link architecture, and the UE uses the first reception index.

[0283] Step 6a: The UE reports to the network side which frequency band of the reception link is switched to shared RX chain.

[0284] Step 7a: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0285] Step 4b: Only the power magnitude relationship two satisfies the third condition

[0286] Step 5b: The UE reports to the network which unconfigured CCs can also share the existing RX chain.

[0287] Step 6b: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0288] Step 4c: Both the power magnitude relationship one and the power magnitude relationship two satisfy the third condition

[0289] Step 5c: The UE switches to a shared RX chain by itself, and the reception index is relaxed to a certain level;

[0290] That is, the UE uses the first link architecture, and the UE uses the first reception index.

[0291] Step 6c: The UE reports to the network which frequency band's reception link is switched to a shared RX chain, and also reports to the network which unconfigured CCs can share the existing RX chain.

[0292] Step 7c: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0293] Step 4d: Both the power magnitude relationship one and the power magnitude relationship three satisfy the third condition

[0294] Step 5d: The UE switches to a shared RX chain by itself, and the reception index is relaxed to a certain level;

[0295] That is, the UE uses the first link architecture, and the UE uses the first reception index.

[0296] Step 6d: The UE reports to the network which frequency band's reception link is switched to a shared RX chain, and also reports to the network which unconfigured CCs can share the existing RX chain.

[0297] Step 7d: The network issues a new CA configuration (i.e., a second carrier aggregation configuration) indicating that the UE can aggregate more CCs, and then Step 8 is performed.

[0298] Step 4e: the first condition, the second condition and the third condition are all satisfied by the first power size relationship, the second power size relationship and the third power size relationship;

[0299] Step 5e: the UE switches to the shared RX chain by itself, and the reception index is relaxed to a certain level;

[0300] That is, the UE uses the first link architecture, and the UE uses the first reception index.

[0301] Step 6e: the UE reports to the network side which frequency band of the reception link is switched to the shared RX chain, and also reports to the network which unconfigured CCs can share the existing RX chain. And which unconfigured CCs can share the idle RX chain.

[0302] Step 7e: the network issues a new CA configuration (i.e. the second carrier aggregation configuration) to indicate that the UE can aggregate more CCs, and then step 8 is performed.

[0303] Step 4f: the first condition, the second condition and the third condition are not all satisfied by the first power size relationship, the second power size relationship and the third power size relationship;

[0304] Step 5f: the UE maintains the separate RX chain state unchanged, and the CA configuration is also unchanged.

[0305] That is, the UE continues to use the second link architecture.

[0306] Step 8: if a certain power size relationship no longer satisfies the third condition;

[0307] Step 9: the UE reports relevant information (i.e. the first information) to the network side;

[0308] Step 10: the network issues a new CA configuration to indicate that the UE uses the new CA configuration, and the reception link is all or partially returned to a CC independent use state. The reception index is changed accordingly.

[0309] That is, the UE uses the second link architecture and the second reception index based on the new CA configuration (such as the first carrier aggregation configuration) issued by the network.

[0310] Embodiment Four:

[0311] In Embodiment Two and Embodiment Three, the operation of the UE switching to the shared RX chain link state by itself can be performed under the condition that the UE does not receive the network side condition that does not allow it to switch to the shared link, i.e. the terminal can use the first link architecture without receiving the third information, which is used to indicate that the terminal is not allowed to use the first link architecture.

[0312] Embodiment Five

[0313] In Embodiment Five, compared with Embodiment Two, the UE can also report the fifth information to the network, and the network judges whether the first condition of shared RX chain is met, and then instructs the UE to perform the link switching operation. When the first condition is no longer met, the network instructs the UE to switch the receiving link back to the separate RX chain state.

[0314] Referring to FIG. 13, the specific steps include:

[0315] Step 1: The UE reports its supported all CA configuration combinations to the network.

[0316] Step 2: The network selects the configuration for the UE from the supported CA configurations.

[0317] The network instructs the UE the information of the blockers (i.e., the first signal) between the carriers in each frequency band corresponding to the CA configuration.

[0318] Step 3: The UE detects the power of the blockers and reports the corresponding fifth information to the network, and then performs Step 4a or Step 4b.

[0319] For example, the UE periodically reports the corresponding fifth information to the network, or the UE reports the corresponding fifth information to the network when the power of the detected blockers meets a preset condition (such as the third condition). It can be understood that the condition and manner of the UE reporting the fifth information in this embodiment are not limited.

[0320] Step 4a: The network judges whether it can be switched to shared RX chain, and then issues the related signaling (i.e., the second information) to the UE;

[0321] Step 5a: The UE switches to shared RX chain, and the receiving index is relaxed to a certain level, and then Step 6 is performed.

[0322] That is, the UE uses the first link architecture, and uses the first receiving index.

[0323] Step 4b: The network judges that it cannot be switched to shared RX chain at this time, and then does not issue the related signaling.

[0324] Step 5b: The UE maintains the separate RX chain state unchanged.

[0325] That is, the UE uses the second link architecture.

[0326] Step 6: Network judges that some carriers cannot continue to use shared RX chain between them;

[0327] Step 7: Network indicates all or part of the UE's receiving link to return to a carrier to use a link state independently. The receiving index has a corresponding change.

[0328] That is, the UE uses the second link architecture and the second receiving index.

[0329] Embodiment six:

[0330] Compared with embodiment five, the UE can aggregate more carriers after switching to shared RX chain, and correspondingly support more CA configurations.

[0331] At this time, the UE reports all CA configurations and is divided into two categories, namely, the UE can support by default and the UE can support after switching to shared RX chain.

[0332] When the preset condition (such as the third condition) is met, the UE reports the fifth information to the network, and the network judges to instruct the link switching operation when the first condition of shared RX chain is met. When the first condition is no longer met, the network instructs the UE to a new CA configuration and switches the receiving link back to an independent state.

[0333] The corresponding process is as follows, there are several possibilities:

[0334] 1. In an embodiment, the network instructs the UE the information of the blocker between each carrier in each frequency band corresponding to the CA configuration, and the network judges whether the carriers already allocated can be shared by link through the information reported by the UE.

[0335] Referring to FIG. 14, the specific steps include:

[0336] Step 1: UE supports the capability of share RX chain, and reports all CA configuration combinations it supports. One is supported by default, and the other is supported after switching to shared RX chain.

[0337] Step 2: Network selects the configuration of the UE in the default supported CA configuration. The network instructs the UE the information of the blocker (i.e., the first signal) between each carrier in each frequency band corresponding to the CA configuration.

[0338] Step 3: UE detects the power of the blocker, and reports the corresponding information to the network when a certain condition is met, and then executes step 4a or step 4b.

[0339] Step 4a: The network judges that the shared RX chain can be switched, and sends the UE relevant signaling (second information); meanwhile, the network sends the UE a new CA configuration (i.e., a second carrier aggregation configuration) to indicate that more CCs are aggregated.

[0340] Step 5a: The UE switches to the shared RX chain, and the reception index is relaxed to a certain level. Meanwhile, the UE uses the new CA configuration, and then performs step 6.

[0341] Step 4b: If the network judges that the shared RX chain cannot be switched at this time, no relevant signaling is sent.

[0342] Step 5b: The UE maintains the separate RX chain state unchanged, and the CA configuration is unchanged.

[0343] Step 6: The network judges that the shared RX chain cannot be used between some carriers.

[0344] Step 7: The network sends a new CA configuration to indicate that all or part of the reception links of the UE are returned to a state of using one link for one CC. The reception index is changed accordingly.

[0345] That is, the UE uses the second link architecture and the second reception index based on the new CA configuration (such as a fifth carrier aggregation configuration) sent by the network.

[0346] 2. In another embodiment, the network indicates to the UE information about the blocker category one between carriers in each frequency band corresponding to the CA configuration of the UE. The network indicates to the UE information about the blocker category two between the configured carriers and the unconfigured carriers in the frequency band. Compared with the embodiment shown in FIG. 14, the network can further judge whether the unconfigured carriers can share the RX link of the configured carriers based on the information reported by the UE.

[0347] Referring to FIG. 15, the specific steps include:

[0348] Step 1: The UE reports its supported CA configuration combinations in the support of the shared RX chain. One type is the default support, and the other type is the support after switching to the shared RX chain.

[0349] Step 2: The network selects a configuration for the UE in the default supported CA configuration. The network indicates to the UE the information of blocker class one among CCs in each band corresponding to the CA configuration. The network indicates to the UE the information of blocker class two between the configured CCs and the un-configured CCs in the band.

[0350] Step 3: The UE detects the power of blocker class one and the power of blocker class two, and reports the corresponding information (i.e., the fifth information) to the network when a certain condition (e.g., the third condition) is met, and then performs step 4a or step 4b or step 4c or step 4d.

[0351] Step 4a: The network determines that only some configured carriers can share RX chains.

[0352] Step 5a: The network sends relevant signaling (e.g., the second information) to the UE to indicate that it switches to shared RX chains, and sends a new CA configuration to the UE to indicate that it aggregates more carriers.

[0353] Step 6a: The UE switches to shared RX chains and relaxes the reception index to a certain level. At the same time, the UE uses the new CA configuration, and then performs step 7.

[0354] Step 4b: The network determines that only some un-configured carriers can share the existing RX chains.

[0355] Step 5b: The network sends a new CA configuration to the UE to indicate that it aggregates more carriers, and sends relevant signaling to indicate that it switches to shared RX chains.

[0356] Step 6b: The UE switches to shared RX chains and relaxes the reception index to a certain level. At the same time, the UE uses the new CA configuration, and then performs step 7.

[0357] Step 4c: The network determines that some configured carriers can share RX chains, and some un-configured carriers can also share the existing RX chains.

[0358] Step 5c: The network sends relevant signaling (e.g., the second information) to the UE to indicate that it switches to shared RX chains, and sends a new CA configuration to the UE to indicate that it aggregates more carriers and can share the existing RX chains.

[0359] Step 6c: The UE switches to shared RX chains and relaxes the reception index to a certain level. At the same time, the UE uses the new CA configuration, and then performs step 7.

[0360] Step 4d: Network judges that no carrier can share RX chain.

[0361] Step 5d: Network judges that it cannot switch to shared RX chain link, and then does not issue relevant signaling.

[0362] Step 6d: UE maintains the separate RX chain state unchanged, and the CA configuration is unchanged.

[0363] That is, the UE uses the second link architecture.

[0364] Step 7: Network judges that some carriers cannot continue to use shared RX chain.

[0365] Step 8: Network issues a new CA configuration to indicate that all or part of the receiving link of the UE returns to a state of using a link independently on one carrier. The receiving index is changed accordingly.

[0366] That is, the UE uses the second link architecture and the second receiving index based on the new CA configuration (such as the fifth carrier aggregation configuration) issued by the network.

[0367] 3. In another embodiment, the network indicates to the UE the information of the blocker category one between the carriers in each frequency band corresponding to the CA configuration of the UE. The network indicates to the UE the information of the blocker category two between the configured carriers and the unconfigured carriers in the frequency band. The network indicates to the UE the information of the blocker category three between the unconfigured carriers in the frequency band. Compared with the embodiment shown in FIG. 11, the network can further judge whether the unconfigured carriers can share the idle RX chain through the information reported by the UE.

[0368] Referring to FIG. 16, the specific steps include:

[0369] Step 1: UE reports all CA configuration combinations supported by the UE, including the configurations that are supported by default and the configurations that can be supported only by switching to shared RX chain.

[0370] Step 2: Network selects the configuration for the UE from the CA configurations supported by default.

[0371] The network indicates to the UE the information of the blocker category one between the carriers in each frequency band corresponding to the CA configuration of the UE.

[0372] The network indicates to the UE the information of the blocker category two between the configured carriers and the unconfigured carriers in the frequency band.

[0373] The network indicates to the UE the information of blocker category three between the CCs which are not configured.

[0374] Step 3: The UE detects the power of blocker category one, two and three, and reports the corresponding information to the network when certain conditions (for example, the third condition) are met, and then performs step 4a or step 4b or step 4c or step 4d or step 4e or step 4f.

[0375] Step 4a: The network determines that only some of the configured CCs can share RX chains.

[0376] Step 5a: The network issues relevant signaling (for example, the second information) to the UE to indicate that it switches to shared RX chains.

[0377] At the same time, the network issues a new CA configuration to the UE to indicate that it aggregates more carriers.

[0378] Step 6a: The UE switches to shared RX chains, and the reception index is relaxed to a certain level. At the same time, the UE uses the new CA configuration, and then performs step 7.

[0379] That is, the UE uses the first link architecture, and uses the first reception index.

[0380] Step 4b: The network determines that only some of the unconfigured carriers can share the existing RX chains.

[0381] Step 5b: The network issues a new CA configuration (second carrier aggregation configuration) to the UE to indicate that it aggregates more carriers; at the same time, it issues relevant signaling (for example, the second information) to indicate that it switches to shared RX chains.

[0382] Step 6b: The UE switches to shared RX chains, and the reception index is relaxed to a certain level. At the same time, the UE uses the new CA configuration, and then performs step 7.

[0383] That is, the UE uses the first link architecture, and uses the first reception index.

[0384] Step 4c: The network determines that some of the configured carriers can share RX chains, and some of the unconfigured carriers can also share the existing RX chains.

[0385] Step 5c: The UE switches to shared RX chains, and the reception index is relaxed to a certain level. At the same time, the UE uses the new CA configuration.

[0386] Step 6c: UE switches to shared RX chain and relaxes the reception metric to a certain level. Meanwhile, UE uses the new CA configuration and then performs step 7.

[0387] Step 4d: Network judges that some configured carriers can share RX chain and some unconfigured carriers can share idle RX chain.

[0388] Step 5d: Network sends relevant signaling to UE to indicate switching to shared RX chain.

[0389] Meanwhile, new CA configuration is sent to indicate aggregating more carriers and the new carriers can share idle RX chain.

[0390] Step 6d: UE switches to shared RX chain and relaxes the reception metric to a certain level.

[0391] Meanwhile, UE uses the new CA configuration and then performs step 7.

[0392] Step 4e: Network judges that some configured carriers can share RX chain, some unconfigured carriers can share existing RX chain, and some unconfigured carriers can share idle RX chain.

[0393] Step 5e: Network sends relevant signaling to UE to indicate switching to shared RX chain; meanwhile, new CA configuration is sent to indicate aggregating more carriers, some of which can share existing RX chain and some of which can share idle RX chain.

[0394] Step 6e: UE switches to shared RX chain and relaxes the reception metric to a certain level. Meanwhile, UE uses the new CA configuration and then performs step 7.

[0395] Step 4f: Network judges that no carrier can share RX chain.

[0396] Step 5f: Network judges that it cannot switch to shared RX chain and does not send relevant signaling.

[0397] Step 6f: UE maintains the separate RX chain state and the CA configuration does not change.

[0398] Step 7: Network judges that some CCs cannot continue to use shared RX chain.

[0399] Step 8: The network issues a new CA configuration, indicating that all or part of the UE's receiving link is returned to a CC independent use of a link state. The receiving index has a corresponding change.
