[0054] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).
[0055] For ease of understanding, the following explains some aspects of the embodiments of this application:
[0056] 1:1Rx Reduced Capability (RedCap) and 2Rx RedCap
[0057] Based on the number of receiving antennas, NR RedCap terminals can be divided into two types: 1-antenna RedCap (1Rx RedCap) terminals and 2-antenna RedCap (2Rx RedCap) terminals. When performing downlink signal measurements, the accuracy of the measurement results from a 1-antenna RedCap terminal will differ from that of a 2-antenna RedCap terminal. Rx stands for Receive.
[0058] In NR systems, the network provides various parameter configurations based on measurement results. For example, a terminal determines whether it can camp on Cell 1 based on measurements of the Synchronization Signal Block (SSB) of Cell 1 (i.e., if the measurement result is below a configured threshold, camping is not allowed). Typically, the parameter configurations provided by the network (such as the configured thresholds mentioned above) are applicable to 2Rx RedCap terminals; for 1Rx RedCap, a fixed offset needs to be applied to the configured thresholds.
[0059] For example: H2 = H1 + offset;
[0060] In the above formula, H1 is the threshold configured for 2Rx RedCap devices in the network; H2 is the threshold obtained based on H1 and applied to 1Rx RedCap devices. The offset is the offset in dB, and for NR 1Rx RedCap, the value of the relevant offset is specified by the protocol.
[0061] 2: Low Power Wide Area Network (LPWA)
[0062] LPWA is designed to meet the low-power, wide-area coverage, and low-cost communication needs of IoT devices. LPWA technology offers long communication distances, low power consumption, and low cost, making it suitable for the large-scale connectivity and low-power requirements of IoT applications. 6G presents an opportune time to deploy a new generation of higher-performance, lower-cost, and larger-scale LPWA devices. With the rollout of 6G, the LPWA market is expected to experience strong growth. Existing 4G LPWA solutions, such as Narrowband Internet of Things (NB-IoT) and Enhanced Mobile Broadband (eMBB), are not well-compatible. Significant differences in the physical layers of NB-IoT and eMBB user equipment increase the cost of NB-IoT user equipment. Furthermore, NB-IoT user equipment requires dedicated NB-IoT base stations, further increasing network deployment costs and operational efficiency. When designing 6G LPWA solutions, 6G LPWA and eMBB should be as compatible as possible. Accordingly, on the network side, a single 6G base station will simultaneously serve both LPWA and eMBB devices, dynamically optimizing resource allocation for instantaneous service requests. To reduce network deployment and operating costs, future 6G mobile communication systems will consider the organic integration of broadband and narrowband communication as much as possible.
[0063] The integration includes the integration of eMBB and LPWA on the terminal, meaning that the same terminal can work at different times using different modes / technologies (eMBB or LPWA).
[0064] The following description, in conjunction with the accompanying drawings, details the receiving antenna adjustment method, apparatus, and related equipment provided in this application through some embodiments and application scenarios.
[0065] See Figure 2 , Figure 2 This is a flowchart of a receiving antenna adjustment method provided in an embodiment of this application, such as... Figure 2 As shown, the receiving antenna adjustment method includes the following steps:
[0066] Step 101: The terminal uses at least one receiving antenna to measure the reference signal and obtains the measurement result of the reference signal;
[0067] Step 102: The terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal.
[0068] In one implementation, the use of "use" can be understood or replaced with "enable" or "apply". For example, "use at least one receiving antenna" can be replaced with "enable at least one receiving antenna" or "apply at least one receiving antenna".
[0069] In one implementation, the reference signal is used for pilot measurement. For example, the reference signal may include pilot signals, such as SSB and Channel State Information Reference Signal (CSI-RS).
[0070] In one embodiment, the measurement result of the reference signal may include the value of the measurement quantity of the reference signal, such as the value of the Reference Signal Received Power (RSRP) or the value of the Reference Signal Received Quality (RSRQ).
[0071] In one embodiment, the terminal uses at least one receiving antenna to measure a reference signal, which may include: the terminal using at least one receiving antenna to receive the reference signal and measuring the received reference signal.
[0072] In one implementation, the terminal can reduce or increase the number of receiving antennas used based on network configuration.
[0073] The network configuration for reducing or increasing the number of receiving antennas used can be configured via broadcast messages.
[0074] In this embodiment of the application, the terminal can be a multi-receiver antenna terminal, that is, the number of receiving antennas of the terminal is greater than 1.
[0075] In one embodiment, the terminal can be a connected multi-antenna terminal; or, the terminal can be a disconnected multi-antenna terminal (such as a UE). For example, the terminal can be in a disconnected Radio Resource Control (RRC) (RRC Connected) state, including being in an RRC inactive state or an RRC idle state.
[0076] For example, a non-connected multi-antenna terminal (such as a UE) can reduce or increase the number of receiver antennas used based on network (NW) configuration.
[0077] It is understood that the measurement results of the reference signal can be used to characterize the network signal reception strength. A high network signal reception strength indicates that the terminal is in an area with good network coverage; a low network signal reception strength indicates that the terminal is in an area with poor network coverage.
[0078] It should be noted that at least one receiving antenna can also be described as at least one receiving antenna.
[0079] In one embodiment, the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal, which may include at least one of the following:
[0080] When the measurement result of the reference signal is higher than or equal to a first threshold (i.e., characterizing high network signal reception strength), the terminal reduces the number of receiving antennas used.
[0081] When the measurement result of the reference signal is lower than a first threshold, the terminal maintains the number of receiving antennas currently in use, or increases the number of receiving antennas in use.
[0082] In one embodiment, the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal, which may include at least one of the following:
[0083] When the measurement result of the reference signal is lower than or equal to the third threshold (i.e., characterizing the network signal reception strength difference), the terminal increases the number of receiving antennas used.
[0084] When the measurement result of the reference signal is higher than the third threshold, the terminal maintains the number of receiving antennas currently in use, or reduces the number of receiving antennas in use.
[0085] In one implementation, when the terminal is in a disconnected state (such as RRC IDLE or RRC Inactive state), if a first condition is met, the number of receiving antennas used is reduced, and N receiving antennas are used for downlink monitoring or measurement; if a second condition is met, the number of receiving antennas used is increased, and M receiving antennas are used for downlink monitoring or measurement, where M>N, M can be the maximum number of receiving antennas that the terminal can use, or M can be less than the maximum number of receiving antennas that the terminal can use.
[0086] The first condition is one or more of the following:
[0087] Based on M receiving antennas, the measured value of the downlink pilot obtained by the terminal is higher than or equal to the first threshold configured in the cell;
[0088] Based on N receiving antennas, the measured value of the downlink pilot obtained by the terminal is higher than or equal to the second threshold configured in the cell;
[0089] Second condition:
[0090] Based on N receiving antennas, the measured value of the downlink pilot obtained by the terminal is lower than or equal to the third threshold configured in the cell.
[0091] In related technologies, eMBB and LPWA modes or technologies operate with different numbers of receiving antennas. Typically, LPWA uses fewer receiving antennas than eMBB.
[0092] In one embodiment, the terminal in this application can be a terminal that simultaneously supports eMBB and LPWA features, with the two features operating in a time-sharing manner. When the terminal is in an idle state, in areas with good network signal conditions, the LPWA feature can be used, employing fewer receiving antennas for cell selection or reselection, receiving paging messages, and performing pilot measurements, thus saving power. In areas with poor network signal conditions (i.e., areas with poor signal coverage), the eMBB feature can be used, employing more receiving antennas for cell selection or reselection, receiving paging messages, and performing pilot measurements, to ensure the terminal's communication performance. It should be noted that terminals supporting multiple features naturally have the ability to shut down some receiving antennas. This explanation only uses a terminal that simultaneously supports eMBB and LPWA features as an example; the key point is the number of receiving antennas, not which feature is used.
[0093] In this embodiment, the terminal uses at least one receiving antenna to measure a reference signal and obtains the measurement result of the reference signal; the terminal adjusts the number of receiving antennas used based on the measurement result of the reference signal. In this way, the terminal can dynamically adjust the number of receiving antennas used according to the measurement result of the reference signal, thereby reducing the terminal's energy consumption and achieving energy-saving effects.
[0094] Optionally, the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal, including at least one of the following:
[0095] If the at least one receiving antenna is M receiving antennas and the first condition is met, the terminal reduces the number of receiving antennas used.
[0096] If at least one receiving antenna is N receiving antennas and the second condition is met, the terminal increases the number of receiving antennas used.
[0097] Where M is greater than N, and both M and N are positive integers;
[0098] The first condition includes any one of the following:
[0099] The measurement result of the reference signal obtained based on the M receiving antennas is higher than the first threshold;
[0100] The measurement result of the reference signal obtained based on N of the M receiving antennas is higher than the second threshold;
[0101] The measurement result of the reference signal obtained based on the M receiving antennas is higher than a first threshold, and the measurement result of the reference signal obtained based on N of the M receiving antennas is higher than a second threshold;
[0102] The second condition includes:
[0103] The measurement results of the reference signal obtained based on the N receiving antennas are below the third threshold.
[0104] Wherein, M can be the maximum number of receiving antennas that the terminal can use, or M can be less than the maximum number of receiving antennas that the terminal can use; this embodiment does not limit this.
[0105] In one alternative implementation, M = 2, N = 1; or, M = 4, N = 2; or, M = 4, N = 1.
[0106] In one embodiment, the first condition includes: the measurement result of the reference signal obtained based on the M receiving antennas is higher than a first threshold; reducing the number of receiving antennas used by the terminal may include: the terminal adjusting the number of receiving antennas used from the M receiving antennas to N receiving antennas out of the M receiving antennas. N can be agreed upon by a protocol, determined based on indication information sent by the network-side device, or determined by the terminal itself; this embodiment does not limit this.
[0107] In one embodiment, the first condition includes: the measurement result of the reference signal obtained based on the M receiving antennas is higher than a first threshold, and the measurement result of the reference signal obtained based on N receiving antennas out of the M receiving antennas is higher than a second threshold. The terminal reducing the number of receiving antennas used may include: the terminal adjusting the number of receiving antennas used from the M receiving antennas to N receiving antennas out of the M receiving antennas. N can be agreed upon by a protocol, determined based on indication information sent by the network-side device, or determined by the terminal itself; this embodiment does not limit this.
[0108] It should be noted that when the at least one receiving antenna is M receiving antennas, the measurement result of the reference signal obtained based on the M receiving antennas can refer to the measurement result of the reference signal obtained by calculating the reference signal received by the M receiving antennas using the M receiving antennas.
[0109] In one embodiment, the first condition includes: the measurement result of the reference signal obtained based on N receiving antennas out of the M receiving antennas is higher than a second threshold. The terminal reducing the number of receiving antennas used may include: the terminal adjusting the number of receiving antennas used from the M receiving antennas to N receiving antennas out of the M receiving antennas. N can be agreed upon by a protocol, determined based on indication information sent by the network-side device, or determined by the terminal itself; this embodiment does not limit this.
[0110] It should be noted that when the at least one receiving antenna is M receiving antennas, the measurement result of the reference signal obtained based on N receiving antennas among the M receiving antennas can refer to the measurement result of the reference signal calculated by using M receiving antennas to receive the reference signal and the reference signal received by N receiving antennas among the M receiving antennas.
[0111] Additionally, reducing the number of receiving antennas used by the terminal may include reducing the number of receiving antennas used to receive reference signals; or, reducing the number of receiving antennas used to measure reference signals.
[0112] In one embodiment, if the at least one receiving antenna is M receiving antennas and the first condition is not met, the terminal continues to use M receiving antennas.
[0113] In one embodiment, the second condition includes: the measurement result of the reference signal obtained based on the N receiving antennas is lower than a third threshold; the increase in the number of receiving antennas used by the terminal may include: the terminal adjusting the number of receiving antennas used from the N receiving antennas to M receiving antennas. M can be agreed upon by the protocol, determined based on the indication information sent by the network-side device, or determined by the terminal itself; this embodiment does not limit this.
[0114] It should be noted that when the at least one receiving antenna is N receiving antennas, the measurement result of the reference signal obtained based on the N receiving antennas can refer to the measurement result of the reference signal obtained by calculating the reference signal received by the N receiving antennas using the N receiving antennas.
[0115] In addition, increasing the number of receiving antennas used by the terminal may include increasing the number of receiving antennas used to receive reference signals; or increasing the number of receiving antennas used to measure reference signals.
[0116] In one embodiment, if the at least one receiving antenna is N receiving antennas and the second condition is not met, the terminal continues to use N receiving antennas.
[0117] It should be noted that the term "higher than" used in the embodiments of this application for determining whether a condition (such as the first condition) is met is equivalent to "lower than or equal to" used for determining whether a condition is not met. Furthermore, as another way of expressing this term, "higher than" used for determining whether a condition (such as the first condition) is met can be replaced with "higher than or equal to," while "lower than" is used for determining whether a condition is not met.
[0118] Furthermore, the term "lower than" used in the embodiments of this application for determining whether a condition (such as the second condition) is met is contrasted with "higher than or equal to" used for determining whether a condition is not met. Alternatively, "lower than" used for determining whether a condition (such as the second condition) is met can be replaced with "lower than or equal to," while "higher than" is used for determining whether a condition is not met.
[0119] In this application, when the at least one receiving antenna is M receiving antennas and the first condition is met, the terminal reduces the number of receiving antennas used, thereby allowing the terminal to reduce the number of receiving antennas used in areas with good network coverage and reduce terminal power consumption; and / or, when the at least one receiving antenna is N receiving antennas and the second condition is met, the terminal increases the number of receiving antennas used, thereby allowing the terminal to increase the number of receiving antennas used in areas with poor network coverage, improve the receiving antenna gain, and reduce the probability of the terminal missing paging or moving out of the coverage area due to poor network coverage.
[0120] Optionally, the terminal reduces the number of receiving antennas used, including: the terminal uses the N receiving antennas for downlink monitoring or measurement;
[0121] And / or,
[0122] The terminal increases the number of receiving antennas used, including: the terminal uses M receiving antennas for downlink monitoring or measurement.
[0123] In this embodiment of the application, when the at least one receiving antenna is M receiving antennas and the first condition is met, the terminal uses the N receiving antennas for downlink monitoring or measurement, thereby allowing the terminal to reduce the number of receiving antennas used in areas with good network coverage and reduce terminal power consumption; and / or, when the at least one receiving antenna is N receiving antennas and the second condition is met, the terminal uses M receiving antennas for downlink monitoring or measurement, thereby allowing the terminal to increase the number of receiving antennas used in areas with poor network coverage, improve the receiving antenna gain, and reduce the probability of the terminal missing paging or moving out of the coverage area due to poor network coverage.
[0124] Optionally, the first threshold is agreed upon by the protocol or determined based on indication information sent by the network-side device; and / or,
[0125] The second threshold is determined by the protocol or based on indication information sent by the network-side device; and / or,
[0126] The third threshold is determined by the protocol or by the instruction information sent by the network-side device.
[0127] In one embodiment, the first threshold can be determined by indication information sent by the network-side device. For example, the terminal can receive fourth indication information sent by the network-side device, which can indicate the value of the first threshold; or, the fourth indication information can indicate an offset value, and the terminal can determine the first threshold based on the offset value indicated by the fourth indication information and a preset reference threshold. This embodiment does not limit the indication method of the first threshold.
[0128] In one embodiment, the second threshold can be determined by indication information sent by the network-side device. For example, the terminal can receive a fifth indication information sent by the network-side device, which can indicate the value of the second threshold; or, the fifth indication information can indicate an offset value, and the terminal can determine the second threshold based on the offset value indicated by the fifth indication information and a preset reference threshold. This embodiment does not limit the indication method of the second threshold.
[0129] In one embodiment, the third threshold can be determined by indication information sent by the network-side device. For example, the terminal can receive a sixth indication information sent by the network-side device, which can indicate the value of the third threshold; or, the sixth indication information can indicate an offset value, and the terminal can determine the third threshold based on the offset value indicated by the sixth indication information and a preset reference threshold. This embodiment does not limit the indication method of the third threshold.
[0130] It should be noted that the second threshold can be the same as the third threshold. In this case, to save signaling overhead, the fifth indication information and the sixth indication information can be the same indication information; or the second threshold can be different from the third threshold.
[0131] In one implementation, when the second threshold and the third threshold are different, the second threshold is greater than the third threshold.
[0132] Optionally, the method further includes:
[0133] The terminal receives the first instruction information sent by the network-side device;
[0134] The terminal determines, based on the first indication information, the number of receiving antennas that are allowed to be adjusted or the number of receiving antennas that are not allowed to be adjusted.
[0135] The first indication information may be carried in system information (or broadcast messages). The first indication information may be sent by the cell where the terminal is located.
[0136] In one embodiment, the first indication information is used to indicate whether the number of receiving antennas used for adjustment is permitted. Specifically, the number of receiving antennas used for adjustment can be indicated by whether or not the first indication information is carried, or by the value of the first indication information.
[0137] For example, when the first indication information is a first value, the first indication information indicates that the terminal is allowed to adjust the number of receiving antennas used; when the first indication information is a second value other than the first value, the first indication information indicates that the terminal is not allowed to adjust the number of receiving antennas used.
[0138] Alternatively, when the first indication information is carried in the system information and has a first value, the terminal is allowed to adjust the number of receiving antennas used; when the first indication information is not carried in the system information, the terminal is not allowed to adjust the number of receiving antennas used. This embodiment does not limit the specific implementation of the first indication information.
[0139] In one embodiment, the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal, including: when the number of receiving antennas allowed to be adjusted is determined based on the first indication information, the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal.
[0140] In this embodiment, the terminal receives first indication information sent by the network-side device; the terminal determines, based on the first indication information, the number of receiving antennas that are allowed to be adjusted, or the number of receiving antennas that are not allowed to be adjusted. Thus, the terminal can determine whether the number of receiving antennas that are allowed to be adjusted is determined through the first indication information.
[0141] Optionally, the reference signal is a reference signal transmitted by the first cell, and the terminal adjusts the number of receiving antennas used based on the measurement results of the reference signal, including:
[0142] When the at least one receiving antenna is M receiving antennas, the terminal determines the adjusted measurement result based on the measurement result of the reference signal obtained by N receiving antennas among the M receiving antennas and the first offset value;
[0143] If the terminal determines, based on the adjusted measurement results, that the first cell meets the Scriterion for cell selection or is a suitable cell, it reduces the number of receiving antennas used.
[0144] The adjusted measurement result can be the sum or difference of the measurement results of the reference signal obtained by the N receiving antennas and the first offset value, and this embodiment does not limit it.
[0145] In one embodiment, the measurement result of the reference signal obtained from N of the M receiving antennas can refer to the measurement result of the reference signal obtained by using M receiving antennas to receive the reference signal and calculating the reference signal received by N of the M receiving antennas.
[0146] It should be noted that the first offset value can be determined by the protocol or by the indication information sent by the network-side device; this embodiment does not limit this.
[0147] In one embodiment, after reducing the number of receiving antennas used, the number of receiving antennas used by the terminal is N. The reduction of the number of receiving antennas used by the terminal includes: the terminal reducing the number of receiving antennas used to N, or the terminal using the N receiving antennas for downlink monitoring or measurement, wherein N is less than M.
[0148] In addition, the first cell can be the cell where the terminal is stationed.
[0149] In this embodiment of the application, when the at least one receiving antenna is M receiving antennas, the terminal determines the adjusted measurement result based on the measurement result of the reference signal obtained by N receiving antennas among the M receiving antennas and the first offset value; when the terminal determines that the first cell meets the S criterion or is a suitable cell based on the adjusted measurement result, the number of receiving antennas used is reduced, thereby allowing the terminal to reduce the number of receiving antennas used in areas with good network coverage and reduce terminal power consumption.
[0150] Optionally, the reference signal is a reference signal transmitted by the second cell, and the terminal adjusts the number of receiving antennas used based on the measurement result of the reference signal, including:
[0151] When the at least one receiving antenna is N receiving antennas, the terminal determines the adjusted measurement result based on the measurement result of the reference signal obtained by the N receiving antennas and the second offset value;
[0152] If the terminal determines, based on the adjusted measurement results, that the second cell does not meet the S criterion or is not a suitable cell, it increases the number of receiving antennas used.
[0153] The adjusted measurement result can be the sum or difference of the measurement results of the reference signal obtained by the N receiving antennas and the second offset value, and this embodiment does not limit it.
[0154] In one embodiment, the measurement result of the reference signal obtained based on the N receiving antennas can refer to the measurement result of the reference signal obtained by using N receiving antennas to receive the reference signal and calculating the reference signal received by the N receiving antennas.
[0155] It should be noted that the second offset value can be determined by the protocol or by the indication information sent by the network-side device; this embodiment does not limit this.
[0156] In one implementation, after increasing the number of receiving antennas used, the number M of antennas used by the terminal is specified by the protocol, determined based on the indication information sent by the network-side device, or decided by the terminal itself. Increasing the number of receiving antennas used by the terminal includes: the terminal increasing the number of receiving antennas used to M, or the terminal using M receiving antennas for downlink monitoring or measurement, where M is greater than N.
[0157] In addition, the second cell can be the cell where the terminal is camped.
[0158] In this embodiment of the application, when the at least one receiving antenna is N receiving antennas, the terminal determines the adjusted measurement result based on the measurement result of the reference signal and the second offset value obtained by the N receiving antennas; if the terminal determines that the second cell does not meet the S criterion or is not a suitable cell based on the adjusted measurement result, the terminal increases the number of receiving antennas used, thereby enabling the terminal to increase the number of receiving antennas used in areas with poor network coverage, improve the receiving antenna gain, and reduce the probability of the terminal missing paging or moving out of the coverage area due to poor network coverage.
[0159] Optionally, the method further includes:
[0160] The terminal performs a first operation based on the measurement results of the reference signal obtained by N receiving antennas, where N is less than M and M is the maximum number of receiving antennas that the terminal can use.
[0161] The first operation includes at least one of the following:
[0162] Cell reselection assessment; preamble transmission carrier selection; beam selection.
[0163] In one embodiment, the terminal uses N receiving antennas to receive a reference signal and performs a first operation based on the measurement results of the reference signal obtained from the N receiving antennas.
[0164] For example, when the terminal reduces the number of receiving antennas used to N, the terminal performs a first operation based on the measurement results of the reference signal obtained from the N receiving antennas.
[0165] In one embodiment, the measurement result of the reference signal obtained based on the N receiving antennas can refer to the measurement result of the reference signal obtained by using N receiving antennas to receive the reference signal and calculating the reference signal received by the N receiving antennas.
[0166] In one embodiment, the preamble transmission carrier selection may refer to the preamble transmission carrier selection for Random Access Channel (RACH) or Small Data Transmission (SDT).
[0167] In this embodiment, the terminal performs a first operation based on the measurement results of the reference signal obtained from N receiving antennas. The first operation includes at least one of the following: cell reselection evaluation; preamble transmission carrier selection; and beam selection. This allows the terminal to perform the first operation based on an adjusted number of receiving antennas, enabling it to reduce the number of receiving antennas used in areas with good network coverage, thereby further reducing terminal power consumption.
[0168] Optionally, the terminal performs a first operation based on the measurement results of the reference signal obtained from N receiving antennas, including:
[0169] The terminal performs the first operation based on the comparison result of the measurement result of the reference signal obtained by N receiving antennas and the fourth threshold;
[0170] The fourth threshold is determined based on the fifth threshold and the third offset value, wherein the fifth threshold is the threshold corresponding to the M receiving antennas.
[0171] The comparison result can be that the measurement result of the reference signal obtained by the N receiving antennas is higher than (or higher than or equal to) the fourth threshold; or that the measurement result of the reference signal obtained by the N receiving antennas is lower than or equal to (or lower than) the fourth threshold.
[0172] For example, when the comparison result indicates that the measurement result is below the fourth threshold, the terminal performs cell reselection.
[0173] It should be noted that the third offset value can be determined by the protocol or by the indication information sent by the network-side device; this embodiment does not limit this.
[0174] In one embodiment, the fourth threshold can be the difference or sum of the fifth threshold and the third offset value; this embodiment does not limit this.
[0175] Wherein, the fifth threshold is the threshold corresponding to M receiving antennas, which can mean that the fifth threshold is the threshold for comparing the measurement results of the reference signal obtained using M receiving antennas.
[0176] In this embodiment, the terminal performs the first operation based on a comparison between the measurement results of the reference signal obtained from N receiving antennas and a fourth threshold; wherein the fourth threshold is determined based on a fifth threshold and a third offset value, and the fifth threshold is a threshold corresponding to M receiving antennas. Thus, by determining the fourth threshold corresponding to N receiving antennas using the fifth threshold corresponding to M receiving antennas and the third offset value, a more accurate comparison threshold can be obtained, thereby improving the execution effect of the first operation.
[0177] Optionally, the method further includes:
[0178] The terminal sends first information to the network-side device, the first information being information related to the number of receiving antennas used by the terminal.
[0179] In this embodiment of the application, the terminal sends first information to the network-side device. The first information is related to the number of receiving antennas used by the terminal. Thus, the network-side device can obtain the relevant information about the number of receiving antennas used by the terminal through the first information reported by the terminal, which makes it easier for the network-side device to more accurately determine the current status of the terminal.
[0180] Optionally, the first information or information related to the number of receiving antennas used by the terminal includes at least one of the following:
[0181] The number of receiving antennas used by the terminal;
[0182] The second indication information is used to indicate whether the number of receiving antennas used by the terminal is the same as the maximum number of receiving antennas that the terminal can use;
[0183] The third indication information is used to indicate that the number of receiving antennas used by the terminal is less than or equal to the maximum number of receiving antennas that the terminal can use.
[0184] Optionally, M is the maximum number of receiving antennas that the terminal can use;
[0185] And / or,
[0186] N is determined by the protocol or by the instruction information sent by the network-side device.
[0187] It should be noted that for terminals in a disconnected state, related technologies support RedCap terminals with one receiving antenna and RedCap terminals with two receiving antennas using different threshold parameters for cell selection and reselection. However, related technologies do not support terminals with multiple receiving antennas in a disconnected state dynamically reducing the number of receiving antennas communicating with the network under certain conditions, thus failing to provide corresponding terminal energy-saving gains. This application embodiment aims to improve the energy-saving effect of the terminal by using network assistance to reduce the number of receiving antennas used in applications / operations under certain conditions for a terminal with M receiving antennas. Terminals configured with multiple receiving antennas in this application embodiment can achieve energy savings by reducing the number of receiving antennas used in applications.
[0188] The following examples will provide further explanation:
[0189] Example 1:
[0190] The receiving antenna adjustment method includes the following process:
[0191] (1) The terminal (such as UE) receives system information (or broadcast message) sent by the cell it is camped on (hereinafter referred to as Cell1). The system information carries indication information.
[0192] (2) Based on the indication information (i.e., one or more of the first, fourth, fifth, sixth, seventh, and eighth indication information described below) and the measurement results of Cell1, the terminal adjusts the number of antennas used for pilot measurements. The method for adjusting the number of antennas used by the terminal includes at least one of the following:
[0193] (a) Adjust the number of antennas used by the terminal based on the measurement results obtained by measuring with M receiving antennas. The measurement results (described below as Quality_m) can be RSRP or RSRQ, etc.
[0194] If Quality_m is higher than (or equal to) the first threshold value (Hm) obtained based on the fourth indication information, the terminal reduces the number of antennas used for measurement.
[0195] After the terminal reduces the number of antennas, the number of antennas used by the terminal is N. N is specified by the protocol, indicated by the seventh indication information in the cell system information, or determined by the terminal itself.
[0196] (b) Adjust the number of antennas used by the terminal based on the measurement results (Quality_m) obtained by measuring with M receiving antennas and the measurement results (hereinafter referred to as Quality_n) obtained by measuring with N receiving antennas out of the M antennas;
[0197] If Quality_m is higher than the first threshold value (Hm) obtained based on the fourth indication information and Quality_n is higher than the second threshold value (Hn) obtained based on the fifth indication information, the terminal reduces the number of antennas used for measurement.
[0198] After the terminal reduces the number of antennas, the number of antennas used by the terminal is N. N is specified by the protocol, configured by the cell based on the seventh indication information, or determined by the terminal itself.
[0199] (c) Based on the measurement results (Quality_m) obtained by using M receiving antennas; adjust the number of antennas used by the terminal based on the measurement results (Quality_n) obtained by using N receiving antennas out of the M antennas;
[0200] If Quality_n is higher than the second threshold value (Hn) obtained based on the fifth indication information, the terminal reduces the number of antennas used for measurement;
[0201] After the terminal reduces the number of antennas, the number of antennas used by the terminal is N. N is specified by the protocol, configured by the cell based on the seventh indication information, or determined by the terminal itself.
[0202] (d) Adjust the number of antennas used by the terminal based on the measurement results (Quality_n) obtained by using N receiving antennas;
[0203] If the measurement result Quality_n is lower than (or lower than or equal to) the second threshold value (Hn) obtained based on the fifth indication information, the terminal increases the number of antennas used for measurement;
[0204] After the number of antennas in the terminal is increased, the number of antennas M used by the terminal is specified by the protocol or configured by the cell based on the eighth indication information.
[0205] Based on the mechanism in this example, when the terminal is in an area with sufficient signal quality (such as the center of the cell), it can reduce the number of antennas used to reduce power consumption; when the terminal is in an area with insufficient signal quality (such as the edge of the cell), it can increase the number of antennas used to improve the gain of the receiving antenna, thereby ensuring coverage.
[0206] Example 2:
[0207] The receiving antenna adjustment method includes the following process:
[0208] (1) The terminal receives system information (or broadcast message) sent by the cell it is stationed in (hereinafter referred to as Cell1). The system information carries indication information.
[0209] (2) Optionally, the indication information includes first indication information. When the first indication information is a first value, the terminal is allowed to adjust the number of receiving antennas and the terminal executes step (3); in other cases (e.g., the first indication information is not carried, or the value is a value other than the first value), the terminal is not allowed to adjust the number of receiving antennas and the process ends.
[0210] (3) Based on the measurement results of Cell1, the terminal adjusts the number of antennas used for pilot measurements. The method for adjusting the number of antennas used by the terminal includes at least one of the following:
[0211] (a) Adjust the number of antennas used by the terminal based on the measurement results (Quality_n) obtained from the measurement using N receiving antennas out of M antennas;
[0212] If Cell1 satisfies the S criterion or meets the criteria for a suitable cell based on the corrected Quality_n, the terminal reduces the number of antennas used for measurement.
[0213] Corrected Quality_n = Quality_n + offset;
[0214] The offset value can be positive or negative, and the unit can be dB.
[0215] After the terminal reduces the number of antennas, the number of antennas used by the terminal is N. N is specified by the protocol, configured by the cell based on the seventh indication information, or determined by the terminal itself; the offset is specified by the protocol, configured by the cell based on the ninth indication information, or determined by the terminal itself.
[0216] (b) Adjust the number of antennas used by the terminal based on the measurement results (Quality_n) obtained by using N receiving antennas;
[0217] If Cell1 does not meet the S criterion or the judgment condition of a suitable cell based on the corrected Quality_n, the terminal increases the number of antennas used for measurement.
[0218] Corrected Quality_n = Quality_n + offset;
[0219] The offset value can be positive or negative, and the unit can be dB.
[0220] After the number of antennas in the terminal is increased, the number of antennas M used by the terminal is specified by the protocol, configured by the cell based on the eighth indication information, or determined by the terminal itself.
[0221] Based on the mechanism in this example, when the terminal is in an area with sufficient signal quality (such as the center of the cell), it can reduce the number of antennas used to reduce power consumption; when the terminal is in an area with insufficient signal quality (such as the edge of the cell), it can increase the number of antennas used to improve the gain of the receiving antenna and ensure coverage.
[0222] It is understood that the corrected measurement result is used for comparison with the relevant threshold; therefore, correcting the measurement result (i.e., adding offset to the measurement result) is equivalent to adjusting the relevant threshold (i.e., subtracting offset from the threshold). In other words, the measurement result can be corrected, or the relevant threshold can be adjusted without correcting the measurement result. In the embodiments of the application, the two statements should be regarded as corresponding equivalent operations.
[0223] Example 3:
[0224] As in Example 1, the measurement results obtained based on N receiving antennas can be used for cell reselection evaluation, preamble carrier selection for Random Access Channel (RACH) or SDT, beam selection (SSB / CSI Reference Signal (CSI-RS)), etc.
[0225] The measurement result Quality_n obtained by the terminal based on N receiving antennas and the measurement result Quality_m obtained based on M receiving antennas, when used for the same purpose (e.g., RACH preamble transmit beam (SSB / CSI-RS) selection), use threshold values that differ by an offset, the value of which is specified by the protocol or carried in the cell's system information.
[0226] During the subsequent uplink message transmission process (such as RACH or SDT), the terminal can indicate relevant information about the number of receiving antennas currently in use through uplink signals or signaling, such as indicating one or more of the following: the number of receiving antennas used by the terminal (or expressed as the number of antennas); whether the number of receiving antennas used by the terminal is consistent with the maximum number of receiving antennas of the terminal; whether the number of receiving antennas used by the terminal is less than or equal to the maximum number of receiving antennas of the terminal, etc.
[0227] It should be noted that reducing or increasing the number of antennas used can also be described as switching the reception mode or changing the enabled features (such as eMBB, LPWA).
[0228] Through the embodiments of this application, the terminal can reduce the number of receiving antennas used in areas with good network coverage, thereby reducing terminal power consumption; and can increase the number of receiving antennas used in areas with poor network coverage, thereby increasing the receiving antenna gain and reducing the probability of the terminal missing paging or moving out of the coverage area due to poor network coverage.
[0229] See Figure 3 , Figure 3 This is a flowchart of a receiving antenna adjustment method provided in an embodiment of this application, such as... Figure 3 As shown, the receiving antenna adjustment method includes the following steps:
[0230] Step 201: The network-side device performs the target operation;
[0231] The target operation includes at least one of the following:
[0232] Send a first indication message to the terminal, the first indication message being used to indicate the number of receiving antennas that can be adjusted, or to indicate the number of receiving antennas that cannot be adjusted.
[0233] Send target indication information to the terminal, the target indication information being used to indicate a threshold for deciding whether to adjust the number of receiving antennas used;
[0234] The receiving terminal sends first information, which is related to the number of receiving antennas used by the terminal.
[0235] The target indication information can be used to indicate at least one of the following: a first threshold, a second threshold, and a third threshold.
