[0142] In some embodiments, the number of network devices can be one or more. Alternatively, the terminal can send the first information to multiple network devices respectively.

[0143] In some embodiments, the first information is used to indicate at least one of the following: a first number of receivers required by the terminal for non-contiguous carrier aggregation in a first downlink frequency band; a second number of receivers required by the terminal for non-contiguous dual connectivity in the first downlink frequency band; and a maximum number of receivers supported by the terminal.

[0144] In some embodiments, the maximum number of receivers supported by the terminal can be the sum of the number of receivers supported by the terminal for all current downlink frequency bands. For example, if the downlink frequency bands in the current frequency band combination configured by the terminal include Band X1, X2 and X3, and the terminal supports 2 receivers for Band X1, X2 and X3, the maximum number of receivers supported by the terminal can be 6.

[0145] In some embodiments, the first downlink frequency band can be any of the plurality of downlink frequency bands. Alternatively, the terminal can send multiple first information, each first information corresponding to a different downlink frequency band, to report the first number of receivers required by each downlink frequency band for non-contiguous carrier aggregation, or the second number of receivers required by each downlink frequency band for non-contiguous dual connectivity. That is, the terminal can indicate for each downlink frequency band.

[0146] The number of required receivers for the non-contiguous carrier aggregation of the multiple downlink bands or the number of required receivers for the non-contiguous dual connectivity can be the same or different, for example, the number of required receivers for the non-contiguous carrier aggregation of Band X and the number of required receivers for the non-contiguous carrier aggregation of Band Y can both be 2, or can be 1 and 2 respectively.

[0147] In some embodiments, the first number of receivers is greater than 1 and / or the second number of receivers is greater than 1, and the first information is further used to indicate at least one of: whether the first number of receivers can be reduced to a smaller number; whether the second number of receivers can be reduced to a smaller number; a minimum value of the first number of receivers; and a minimum value of the second number of receivers.

[0148] For example, if the terminal requires 8 receivers for the non-contiguous carrier aggregation of the first downlink band, the first information can further indicate whether the first number of receivers for the first downlink band can be reduced, and if the first number of receivers can be reduced, the first information can further indicate a minimum value of the first number of receivers. Alternatively, if the first information indicates that the first number of receivers can be reduced, the minimum value of the first number of receivers can be set to 1 by default.

[0149] In some embodiments, the first information is further used to dynamically configure, by the network device, a maximum number of non-contiguous component carriers. Alternatively, the network device can determine and configure the maximum number of non-contiguous component carriers for the first downlink band according to at least one of the first number of receivers, the second number of receivers, and a maximum number of receivers supported by the terminal.

[0150] Alternatively, the network device can determine and configure the maximum number of non-contiguous component carriers for each downlink band according to the first number of receivers or the second number of receivers corresponding to each downlink band. Alternatively, the network device can configure the maximum number of non-contiguous component carriers for the terminal according to a maximum number of receivers supported by the terminal.

[0151] For example, if the terminal supports 1 receiver for receiving intra-band non-contiguous component carriers on the same band on band X and supports 2 receivers for receiving intra-band non-contiguous component carriers on the same band on band M, when the terminal switches from the intra-band non-contiguous CA scenario on band M to the intra-band non-contiguous CA scenario on band X, one receiver can be left idle, and the network device can configure more component carriers or perform diversity reception to improve throughput or downlink coverage.

[0152] In some embodiments, the terminal has the capability of switching the receiver resources among frequency bands. In which, the terminal can schedule the receiver resources occupied by each frequency band. Alternatively, the terminal can adjust the number of receivers used by each frequency band.

[0153] For example, in the case that the terminal currently uses 2 receivers for Band X and 1 receiver for Band Y, if the number of receivers used by the terminal for Band X can be reduced to a smaller number and more carriers need to be configured on Band Y, the receiver resources can be adjusted, for example, adjusted to use 1 receiver for Band X and 2 receivers for Band Y; or, if the number of receivers used by the terminal for Band X can be reduced to a smaller number and more downlink frequency bands need to be configured, the receiver resources can be adjusted, for example, adjusted to use 1 receiver for Band X, 1 receiver for Band Y and 1 receiver for Band Z.

[0154] In some embodiments, the first information can also be referred to as "capability indication information", "receiver number information", and the like, and the name thereof is not limited in the embodiments of the present disclosure.

[0155] In some embodiments, the network device receives the first information. Alternatively, the network device configures the maximum number of non-contiguous component carriers according to the first information. Alternatively, the network device performs step S2102 after configuring the maximum number of non-contiguous component carriers.

[0156] In step S2102, the network device sends non-contiguous component carriers to the terminal.

[0157] In some embodiments, the number of non-contiguous component carriers sent by the network device is less than the maximum number of non-contiguous component carriers.

[0158] In some embodiments, the network device sends at least one non-contiguous component carrier to the terminal on at least one downlink frequency band. Alternatively, the number of non-contiguous component carriers on any one downlink frequency band is greater than or equal to 2. Alternatively, the multiple non-contiguous component carriers on the same downlink frequency band can be sent by the same network device or by different network devices.

[0159] In some embodiments, the first downlink frequency band is any one of the at least one downlink frequency band, and the number of non-contiguous component carriers on the first downlink frequency band is greater than or equal to 2.

[0160] In some embodiments, the terminal meets at least one of the radio frequency (RF) parameter index requirement or the radio resource management (RRM) index requirement. Alternatively, for a terminal that supports receiving multiple in-band non-contiguous component carriers using one receiver, the terminal meets the RRM index requirement.

[0161] In some embodiments, the terminal satisfying the RF parameter index requirement or the RRM index requirement can mean that at least one of the following satisfies the corresponding requirement: the capability of the terminal itself, the non-contiguous component carrier received by the terminal, and the related parameters in the process of receiving the non-contiguous component carrier by the terminal. Alternatively, the terminal satisfying the RF parameter index requirement or the RRM index requirement can also mean that the performance of the communication system composed of the terminal and the network device satisfies at least one of the RF parameter index requirement or the RRM index requirement.

[0162] In some embodiments, the RF parameter index requirement includes at least one of the following: an adjacent channel selectivity (ACS) requirement for indicating the minimum capability of the terminal to suppress adjacent channel interference; and a receiver sensitivity requirement for indicating the minimum signal strength of the non-contiguous component carrier received by the terminal not exceeding a preset bit error rate threshold.

[0163] In some embodiments, the RRM index requirement includes at least one of the following: a reception timing difference requirement for indicating a first timing difference, the first timing difference being a maximum timing difference of the terminal receiving the non-contiguous component carrier; and a scheduling restriction requirement for indicating a first symbol quantity, the first symbol quantity being a quantity of symbols on which the terminal cannot be scheduled on the non-contiguous component carrier, wherein the reception timing difference of the terminal receiving the non-contiguous component carrier is greater than the maximum timing difference.

[0164] For example, if the reception timing difference of the terminal receiving a plurality of non-contiguous carriers is less than the maximum timing difference described above, a terminal or scheduling restriction requirement can be introduced, wherein when the scheduling restriction requirement is introduced, the terminal cannot be scheduled on Y symbols on the plurality of non-contiguous carriers described above, and Y can be the first symbol quantity described above.

[0165] In some embodiments, the RF parameter index requirement or the RRM index requirement can be predefined by a protocol, for example, the sizes of the maximum timing difference and the first symbol quantity can be predefined by a protocol, and the present disclosure does not limit the values thereof.

[0166] In some embodiments, the terminal receives the non-contiguous component carrier sent by the network device. Alternatively, the terminal receives at least one non-contiguous component carrier sent by the network device on at least one downlink frequency band.

[0224] FIG. 6 is a flow diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 5, the communication method comprises:

[0225] Step S6101, the UE reports capability indication information or the maximum number of receivers it can support.

[0226] In some embodiments, the capability indication information is introduced, which indicates the indication information of the number of receivers (for example, X) required by the UE for intra-band non-contiguous CA or intra-band non-contiguous DC in the same downlink band.

[0227] Optionally, the indication information is per band indication, for example, UE can indicate X as 1 on band n1, and 2 on band n41.

[0228] Optionally, the capability indication information is applicable to the scenario of more than or equal to 2 downlink non-contiguous CCs (intra-band non-contiguous CA or intra-band non-contiguous DC).

[0229] Optionally, X is a positive integer greater than or equal to 1.

[0230] In another embodiment, when the number of receivers is indicated to be greater than 1, such as X>1, the capability indication information can also indicate whether the band can fallback to a number of receivers less than X.

[0231] In some embodiments, the UE can also report the maximum number of receivers it can support. The indication information is per UE indication. For example, UE1 indicates 6, and UE2 indicates 7. That is, for UE1, the maximum number of receivers it can support is 6, and for UE2, the maximum number of receivers it can support is 7.

[0232] In some embodiments, based on the capability indication information and / or the number of receivers the UE can support, the network can dynamically determine and configure the maximum number of component carriers (CCs).

[0233] For example, if a UE supports 1 receiver to receive intra-band non-contiguous CCs on the same band on band X and band Y, and supports 2 receivers to receive intra-band non-contiguous CCs on the same band on band M and band N. For the UE to switch from the intra-band non-contiguous CA scenario on band M or band N to the intra-band non-contiguous CA scenario on band X or band Y, the UE can leave one receiver, and the network can configure more carriers CCs or perform diversity reception to improve throughput or downlink coverage.

[0234] In some embodiments, the UE has the capability to semi-statically switch hardware resources (i.e., Rx chains) between frequency bands.

[0235] For example, for band combination BandX+BandY, if the terminal supports fallback to 1 receiver for BandX, before handover, the terminal can use 2 receivers for BandX and 1 receiver for BandY, and after handover, 1 receiver for BandX and 2 receivers for BandY.

[0236] Optionally, the reason for handover can be that more carriers need to be configured on BandY to improve throughput.

[0237] In another embodiment, if the terminal reports that it supports 2 receiver reception for BandX1, X2 and X3, and the maximum number of receivers reported by the UE is 6, it can only support 3 band combinations: BandX1+BandX2+BandX3. If it is also indicated that a band can support fallback to 1 receiver, the UE can also support more band combinations, such as BandX1+BandX2+BandX3+BandX4.

[0238] In some embodiments, for the above-mentioned introduced capability indication information, new RF parameter index requirements and RRM index requirements can also be introduced, wherein the RF parameter index requirements should at least include the following parameter indexes: ACS; receiver sensitivity (REFSENS); the RRM index requirements should at least include the following requirements: reception timing difference requirements (RTD requirements); scheduling restriction requirements.

[0239] Optionally, the reception timing difference requirements can be used to require that the timing difference of receiving CCs for a UE supporting 1Rx reception of intra-band non-contiguous CCs is not less than Kms, otherwise interruption or scheduling restriction requirements will be introduced; the scheduling restriction requirements are used to require that when the reception timing difference between intra-band non-contiguous CCs is greater than K, the UE cannot be scheduled within N symbols on these CCs.

[0240] In the embodiments of the present disclosure, part or all of the steps, optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.

[0241] The embodiments of the present disclosure further provide a device for implementing any of the above methods, for example, a device comprising units or modules for implementing the steps performed by the terminal in any of the above methods. For another example, another device is provided, comprising units or modules for implementing the steps performed by the network device (e.g., an access network device, a core network functional node, a core network device, a terminal, a network device, etc.) in any of the above methods.
