detailed description

The embodiment of the present application provides a method for reporting capabilities, which is used in a process in which a network device configures SRS resources for a user equipment UE. Specifically, it is applied to the process of configuring the corresponding SRS resource when the network device configures the number of MIMO layers or the number of antenna ports for the UE. When the network device configures the number of MIMO layers or antenna ports for the UE, it does not know the SRS antenna conversion capabilities corresponding to the capabilities that the configured MIMO layers or antenna ports can support. Therefore, it will not configure support for the UE. SRS resources corresponding to the SRS antenna switching capability.

For example, when the UE has an overheating problem, it requests the network device to lower the number of MIMO layers of the UE to alleviate the overheating problem. After the network device lowers the MIMO layer for the UE, the UE may close the corresponding radio link; for example: if the network device lowers the UE’s maximum uplink MIMO layer number, the UE will close the corresponding radio transmission link; if the network device adjusts If the maximum number of downlink MIMO layers of the UE is low, the UE will close the corresponding radio frequency receiving link. However, if the network equipment does not reconfigure the SRS resources for user antenna port conversion accordingly, after the UE closes the corresponding radio transmission link, the UE may not be able to support antenna rotation under normal capabilities, resulting in a waste of some SRS resources ; After the UE closes the corresponding radio frequency receiving link, if the UE still sends SRS in turn according to the antenna under normal capability, the channel quality estimated by the network device according to the SRS will be inconsistent with the channel quality of the PDSCH transmission scheduled by the network device.

The purpose of this application is to report the fallbackable SRS antenna switching capability supported by the UE to the network device so that the network device can configure the corresponding SRS resource according to the fallbackable SRS antenna switching capability reported by the UE.

For another example, the method of the embodiment of the present application may be applied to a process in which a network device responds to a request of the UE to configure SRS resources for the UE. Among them, the UE can request the network device to reconfigure the number of MIMO layers or antenna ports and the corresponding reconfiguration SRS resources for the UE when the load is too heavy, the battery is insufficient, or the UE desires to reduce power for various reasons. In the embodiments of the present application, there is no restriction on the conditions or timing for triggering the network device to configure SRS resources for the UE.

For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the mobile phone 100 performs a reduction in the performance of the processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the mobile phone 100 heats the battery 142 to avoid abnormal shutdown of the mobile phone 100 due to low temperature. In some other embodiments, when the temperature is lower than another threshold, the mobile phone 100 boosts the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

The following describes the method of reporting capabilities provided by the embodiments of this application in detail with reference to Figures 1A and 1B. The basic principle of the method is that the UE reports the backable SRS antenna conversion capabilities it supports to the network device so that the network device can When the number of MIMO layers or the number of antenna ports needs to be reconfigured for the UE, the SRS resources are correspondingly reconfigured for the UE.

It should be noted that the following embodiments only take the user equipment as the mobile phone 100 and the network equipment as the base station 200 as an example. In fact, the same method can be used for any kind of user equipment UE, including the several UEs listed above. And method to report capability to network equipment.

The embodiment of the present application provides a method for reporting capabilities.

In the first embodiment, as shown in FIG. 2, the method may include: the mobile phone 100 sends a first message to the base station 200. The first message includes the SRS antenna conversion capability supported by the mobile phone 100.

Wherein, the first message may also include the backable SRS antenna switching capability supported by the mobile phone 100.

The mobile phone 100 reports to the base station 200 its supported SRS antenna conversion capabilities and backable SRS antenna conversion capabilities through the first message, so that when the base station 200 reconfigures the number of MIMO layers for the mobile phone 100, it can be based on the capabilities supported by the mobile phone 100. The backed-off SRS antenna conversion capability reconfigures the mobile phone 100 with SRS resources for antenna port conversion.

Exemplarily, the mobile phone 100 may send the first message to the base station 200 when the remaining power (30%) of the mobile phone 100 is lower than a preset threshold (the preset threshold is 35%), or when the mobile phone 100 is turned on for the first time.

As shown in FIG. 2, when the base station 200 configures/reconfigures the number of MIMO layers for the mobile phone 100, it can refer to the backable SRS antenna conversion capability supported by the mobile phone 100 in the first message for the corresponding configuration of the mobile phone 100 for the antenna SRS resource for port conversion.

In a possible implementation manner, the retractable SRS antenna switching capability is determined and reported by the mobile phone 100 according to its hardware implementation and/or current SRS resource configuration. For example, the current SRS antenna conversion capability of the mobile phone 100 is configured as 2T4R, that is, the mobile phone 100 can transmit SRS on 2 antenna ports through 4 antennas; correspondingly, the backable SRS antenna conversion capability supported by the mobile phone 100 can be 1T4R and /Or 1T2R, that is, the SRS antenna conversion capability of the mobile phone 100 is to transmit SRS on one antenna port through 4 antennas and/or the SRS antenna conversion capability of the mobile phone 100 is to transmit SRS on one antenna port through 2 antennas.

In another possible implementation manner, the first message may also include the first number of MIMO layers supported by the mobile phone 100;

The back-off SRS antenna switching capability corresponds to the number of second MIMO layers. The second MIMO layer number is less than or equal to the first MIMO layer number.

In the embodiment of the present application, the manner in which the first message carries the first number of MIMO layers supported by the mobile phone 100 may include at least the following two implementation manners:

Implementation manner (1): The first number of MIMO layers supported by the mobile phone 100 is used to identify the maximum number of MIMO layers that the mobile phone 100 can support. The first number of MIMO layers is not only the maximum number of uplink MIMO layers supported by the mobile phone 100, but also the maximum number of downlink MIMO layers supported by the mobile phone 100.

For example, assuming that the number of first MIMO layers is 8, the base station 200 can determine that the maximum number of uplink MIMO layers and the maximum number of downlink MIMO layers supported by the mobile phone 100 are both 8.

In the implementation manner (1), in combination with the foregoing example, the number of second MIMO layers may be less than or equal to the number of first MIMO layers, and the number of MIMO layers supported by the mobile phone 100. For example, if the number of MIMO layers supported by the mobile phone 100 includes 1, 2, 4, and 8, then the second number of MIMO layers can be any of 1, 2, 4, and 8. The second MIMO layer number is applicable to uplink and downlink.

Implementation manner (2): The first number of MIMO layers supported by the mobile phone 100 may include: the maximum number of uplink MIMO layers supported by the mobile phone 100 and the maximum number of downlink MIMO layers supported by the mobile phone 100.

For example, the maximum number of uplink MIMO layers supported by the mobile phone 100 is 4, and the maximum number of downlink MIMO layers supported by the mobile phone 100 is 8. Then, the above-mentioned first number of MIMO layers may include the maximum number of uplink MIMO layers supported by the mobile phone 100 of 4 and the maximum number of downlink MIMO layers supported by the mobile phone 100 of 8.

In implementation (2), in combination with the foregoing example, the number of uplink second MIMO layers may be less than or equal to the number of uplink first MIMO layers, and the number of MIMO layers supported by the mobile phone 100. For example, if the number of uplink MIMO layers supported by the mobile phone 100 includes 1, 2, and 4; then the number of the second uplink MIMO layer can be 1, 2, or 4. The number of downlink second MIMO layers may be less than or equal to the number of downlink first MIMO layers and the number of MIMO layers supported by the mobile phone 100. For example, if the number of downlink MIMO layers supported by the mobile phone 100 includes 1, 2, 4, and 8, then the second number of downlink MIMO layers can be any of 1, 2, 4, or 8.

Wherein, the fallbackable SRS antenna conversion capability supported by the mobile phone 100 corresponds to the second MIMO layer number, specifically: the fallback SRS antenna conversion capability supported by the mobile phone 100 corresponds to at least one second MIMO layer number.

The mobile phone 100 can support at least one frequency band combination, and each frequency band combination includes multiple frequency bands. For example, the mobile phone 100 can support frequency band combination 1, which is frequency band 1 (for example, frequency band 1 is 1800Mhz-1810Mhz) and frequency band 2 (for example, frequency band 2 is a combination of 1820Mhz-1830Mhz). Each frequency band includes multiple carriers. The mobile phone 100 may support some of the aforementioned multiple carriers.

Based on this, in the first scenario, the first number of MIMO layers supported by the mobile phone 100 may include: the maximum uplink MIMO layer supported by the mobile phone 100 on each carrier on each frequency band in each frequency band combination supported by the mobile phone 100 And the maximum number of downlink MIMO layers.

Correspondingly, the second MIMO layer number may be: the number of uplink MIMO layers and/or the number of downlink MIMO layers supported by the mobile phone 100 on each carrier on each frequency band in each frequency band combination supported by the mobile phone 100.

In the foregoing implementation (2), the mobile phone 100 differentiates between uplink and downlink and notifies the base station 200 of the first MIMO layer number as an example. In Example 1, it is assumed that the mobile phone 100 supports two frequency band combinations: frequency band combination 1 (including frequency band 1 and frequency band 3) and frequency band combination 2 (including frequency band 2 and frequency band 4). Taking frequency band 1 in frequency band combination 1 as an example, mobile phone 100 supports carrier 1 and carrier 2 on frequency band 1. The maximum number of uplink MIMO layers supported by the mobile phone 100 on carrier 1 is 4, and the maximum number of downlink MIMO layers is 8. The maximum number of uplink MIMO layers supported by the mobile phone 100 on carrier 2 is 2, and the maximum number of downlink MIMO layers is 4.

Correspondingly, the number of second MIMO layers supported by the mobile phone 100 on carrier 1 is the number of uplink MIMO layers 1, 2, and 4, and the number of downlink MIMO layers 1, 2, 4, and 8; the second MIMO supported by the mobile phone 100 on carrier 2 The number of layers includes uplink MIMO layers 1 and 2, and downlink MIMO layers 2 and 4.

Exemplarily, the mobile phone 100 may send the second message to the base station 200 when the popularity (70°) of the mobile phone 100 is higher than a preset threshold (the preset threshold is 50°).

In the embodiment of the present application, the manner in which the mobile phone 100 expects the maximum number of MIMO layers configured by the base station 200 for the mobile phone 100 in the second message may include at least the following two implementation manners:

Implementation method (1): The maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 is the maximum number of MIMO layers suitable for uplink that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100, and the mobile phone 100 expects the base station 200 to be the mobile phone 100 The configured maximum number of MIMO layers applicable to the downlink.

For example, the mobile phone 100 expects that the maximum number of MIMO layers (third MIMO layer) configured by the base station 200 for the mobile phone 100 is 4. Then the base station 200 can determine the maximum number of uplink MIMO layers and the maximum number of downlink that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 The number of MIMO layers is 4.

In the implementation manner (1), in combination with the foregoing example, the number of the fourth MIMO layer may be less than or equal to the number of the third MIMO layer, and the number of MIMO layers supported by the mobile phone 100. For example, if the number of MIMO layers supported by the mobile phone 100 includes 1, 2 and 4; then the fourth number of MIMO layers can be any of 1, 2, and 4.

The number of downlink fourth MIMO layers may be less than or equal to the number of downlink third MIMO layers and the number of MIMO layers supported by the mobile phone 100. For example, if it is expected that the maximum number of downlink MIMO layers configured by the base station 200 for the mobile phone 100 is 4; then the fourth number of uplink MIMO layers can be 1, 2 or 4.

Wherein, the back-off SRS antenna conversion capability supported by the mobile phone 100 corresponds to the second MIMO layer number, and specifically may be: the back-off SRS antenna conversion capability supported by the phone 100 corresponds to at least one fourth MIMO layer number.

In an implementation manner, the maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 may be the maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 in each frequency range.
