Description

[0001] This application is a divisional application of the invention patent application with the application number 201880001342.1, the application date of September 13, 2018, and the invention title of "Method, Apparatus, Device, and Storage Medium for Reporting Beam Measurement Report". Technical Field

[0002] Embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a method, apparatus, device, and storage medium for reporting beam measurement reports. Background Art

[0003] In a 5G NR (New Radio) system, an access network device and a terminal can use beams to transmit and receive information. For example, control signaling and service data exchanged between the access network device and the terminal can both be transmitted and received using beams.

[0004] In the related art, the terminal determines the receiving beam of DCI (Downlink Control Information) in the following manner: After the terminal measures the beam according to the measurement configuration provided by the access network device, it sends a beam measurement report to the access network device. The beam measurement report includes the RS (Reference Signal) type corresponding to the beam, the RS identifier, and the L1-RSRP (Layer1-Reference Signal Received Power); the access network device determines at least one Type D TCI (Transmission Configuration Indication) state based on the beam measurement report sent by the terminal, and each TCI state corresponds to an RS identifier; the access network device notifies the terminal of the above at least one TCI state through RRC (Radio Resource Control) signaling, including the identifier of the TCI state and its corresponding RS type and RS identifier; if the RRC signaling informs multiple TCI states, the access network device then uses MAC (Medium Access Control) CE (Control Element) signaling to activate one of the multiple TCI states. The activated TCI state is the transmission state configuration of the PDCCH (Physical Downlink Control Channel) for this terminal by the access network device, that is, it notifies the terminal that the receiving beam used to receive the DCI on the PDCCH should be the same as the receiving beam used to receive the RS corresponding to this TCI state. After that, the terminal can use the determined receiving beam to receive the DCI on the PDCCH.

[0005] In addition, the terminal can determine the receiving beam for downlink data in a similar manner: after the access network device determines multiple TCI states based on the beam measurement report of the terminal, it notifies the terminal of the above-mentioned multiple TCI states through RRC signaling; then, the access network device activates several (such as at most 8) of the above-mentioned multiple TCI states using MAC CE signaling, and then tells the terminal through DCI which one of the activated several TCI states is used for the PDSCH (Physical Downlink Shared Channel). The TCI state notified through DCI is the transmission state configuration of the PDSCH of the access network device for this terminal, that is, it tells the terminal that the receiving beam used to receive the downlink data on the PDSCH should be the same as the receiving beam used to receive the RS corresponding to this TCI state. After that, the terminal can use the determined receiving beam to receive the downlink data on the PDSCH.

[0006] When the terminal moves or the antenna direction of the access network device changes, the beams configured by the access network device for the terminal to send downlink control information and downlink data may change. If the TCI state is not updated, the configured transmit and receive beams for the terminal will not be the most appropriate. To update the TCI state, the terminal needs to send a beam measurement report to the access network device. However, currently, the reporting method of the beam measurement report is periodic, semi-static, or aperiodic, and this reporting method is configured by the access network device. Among them, the semi-static reporting method means that the terminal starts to send a beam measurement report to the access network device after receiving the activation signaling sent by the access network device, and the terminal stops reporting when a certain number of times are sent or when receiving the deactivation signaling sent by the access network device. For the periodic and semi-static reporting methods, if the reporting time interval is too small, it will cause more unnecessary reports, which is not conducive to saving the signaling overhead and power consumption of the terminal; if the reporting time interval is too large, it will cause problems such as untimely reporting, resulting in situations such as beam failure. The aperiodic reporting method also has the problem of untimely reporting.

[0007] Therefore, the reporting method of the beam measurement report provided by the related art has an unreasonable and inaccurate reporting timing. Summary of the Invention

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0111] The network architecture and service scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art can understand that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0112] Figure 1 It is a schematic diagram of a network architecture shown according to an exemplary embodiment. The network architecture may include: an access network device 110 and a terminal 120.

[0113] The access network device 110 is deployed in the access network. The access network in the 5G NR system may be referred to as NG-RAN (New Generation - Radio Access Network). The access network device 110 and the terminal 120 communicate with each other through a certain air interface technology, for example, they may communicate with each other through cellular technology.

[0114] The access network device 110 may be a base station (BS). A base station is a device deployed in the access network to provide wireless communication functions for terminals. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different radio access technologies, the names of the devices with base station functions may be different. For example, in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technologies, the name of the "base station" may change. For the convenience of description, in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for terminals are collectively referred to as access network devices.

[0115] The number of terminals 120 is usually multiple, and one or more terminals 120 may be distributed within the cell managed by each access network device 110. The terminal 120 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment (UE), mobile station (MS), terminal device, etc. For the convenience of description, in the embodiments of the present disclosure, the above-mentioned devices are collectively referred to as terminals.

[0116] The "5G NR system" in the embodiments of the present disclosure may also be referred to as the 5G system or the NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure may be applicable to the 5G NR system and may also be applicable to the subsequent evolved systems of the 5G NR system.

[0117] In the technical solution provided by the present disclosure, the terminal obtains beam measurement results, and when the terminal detects that the beam measurement results meet a preset condition, it sends a beam measurement report to the access network device. Compared with the terminal sending a beam measurement report to the access network device in a periodic, aperiodic or semi-static manner, the technical solution provided by the embodiments of the present disclosure overcomes the problems of untimely reporting and a large number of unnecessary reports, and the timing for the terminal to send a beam measurement report is reasonable and accurate. In addition, by the terminal sending a beam measurement report to the access network device when it detects that the beam measurement results meet a preset condition, the access network device can update the TCI state set in a timely manner according to the beam measurement report, ensuring that the terminal selects an appropriate beam for downlink reception. Next, the technical solution provided by the present disclosure will be introduced and described through several embodiments.

[0118] Figure 2 is a flowchart of a method for reporting a beam measurement report shown according to an exemplary embodiment. The method can be applied to Figure 1 the network architecture shown. The method may include the following steps.

[0119] In step 201, the terminal obtains beam measurement results.

[0120] In the embodiments of the present disclosure, the beam measurement results include: channel measurement parameters corresponding to n RSs included in the target RS set, and channel measurement parameters corresponding to m other RSs except the target RS set, where the target RS set corresponds to the target TCI state set, and the target TCI state set includes n TCI states indicated by the access network device to the terminal, n is a positive integer, and m is a positive integer.

[0121] Each TCI state corresponds to each RS respectively, and different TCI states correspond to different RSs.

[0122] In one example, the target TCI state set is the TCI state set of the PDCCH indicated by the access network device to the terminal through RRC signaling, or the TCI state set of the PDCCH activated by the access network device through MAC CE signaling. For a beam transmission scenario, when the terminal determines the receiving beam of the DCI, the access network device can indicate the TCI state set of the PDCCH to the terminal through RRC signaling, and the TCI state set includes at least one TCI state. Optionally, the TCI state set includes at most 64 TCI states. In addition, if the TCI state set of the PDCCH indicated by the access network device to the terminal through RRC signaling includes multiple TCI states, the access network device can also activate one of the multiple TCI states through MAC CE signaling.

[0123] In another example, the set of target TCI states is the set of TCI states of the PDSCH indicated by the access network device to the terminal through RRC signaling, or the set of TCI states of the PDSCH activated through MAC CE signaling. For the beam transmission scenario, when the terminal determines the receiving beam of the downlink data, the access network device may indicate the set of TCI states of the PDSCH to the terminal through RRC signaling, and the set of TCI states includes at least one TCI state. Optionally, the set of TCI states includes at most 64 TCI states. In addition, the access network device may also activate at least one TCI state among the above-mentioned multiple TCI states through MAC CE signaling, such as activating at most 8 TCI states among the above-mentioned multiple TCI states.

[0124] In the embodiments of the present disclosure, other RSs are candidate RSs for updating the set of target TCI states. Optionally, other RSs may be configured by the access network device and informed to the terminal.

[0125] In the embodiments of the present disclosure, the channel measurement parameters may include at least one of the following: channel quality, L1-RSRP, L1-RSRQ (Layer 1-Reference Signal Received Quality), L1-SINR (Layer 1-Signal to Interference and Noise Ratio). When the type of the channel measurement parameter is channel quality or L1-RSRQ or L1-SINR, the terminal needs to measure the RSRP and interference corresponding to each RS. It should be noted that the same receiving beam is used to measure the RSRP and interference corresponding to the same RS.

[0126] It should be noted that which RSs the terminal needs to obtain the channel measurement parameters for can be configured by the access network device and informed to the terminal. In addition, which type of channel measurement parameters the terminal needs to obtain can also be configured by the access network device and informed to the terminal.

[0127] In addition, the terminal may obtain the beam measurement result periodically or aperiodically.

[0128] In step 202, when the beam measurement result meets the preset condition, the terminal sends a beam measurement report to the access network device.

[0129] The preset condition refers to the condition that is pre-set to trigger the terminal to send a beam measurement report to the access network device. The preset condition may be configured by the access network device and informed to the terminal.

[0130] In an embodiment of the present disclosure, the beam measurement report is used to trigger the access network device to update the target TCI state set.

[0131] The terminal can send a beam measurement report to the access network device through the PUCCH (Physical Uplink Control Channel) or the PUSCH (Physical Uplink Shared Channel).

[0132] The beam measurement report may include: identification information of k RSs, and indication information of channel measurement parameters corresponding to the k RSs, where k is an integer greater than 1; among them, the k RSs include: at least one other RS among n RSs and m other RSs whose channel measurement parameters are greater than those of the target RS, and the target RS refers to the RS with the smallest channel measurement parameter among the n RSs.

[0133] The identification information of the RS is also called the RS index and is used to uniquely indicate the RS. Different RSs correspond to different identification information. In an embodiment of the present disclosure, the RS may be an NZP CSI-RS (Non-Zero Power Channel State Information Reference Signal) or an SSB (Synchronization Signal Block).

[0134] Optionally, the preset condition includes any one of the following:

[0135] 1. Among the channel measurement parameters corresponding to each RS included in the beam measurement result, the top w RSs ranked in descending order are different from the beam measurement result obtained last time, where w is a positive integer;

[0136] The beam measurement result obtained by the terminal in step 201 above may be referred to as the beam measurement result obtained this time. The beam measurement result obtained last time is the beam measurement result obtained once before this time. In addition, the value of w can be preset, such as configured by the access network device, and the embodiment of the present disclosure does not limit this.

[0137] For example, the target RS set includes the following RSs: RS#1, RS#2, and RS#3, and the other RSs include RS#4 and RS#5. In the previously obtained beam measurement results, the RSs are sorted in descending order of channel measurement parameters as follows: RS#1, RS#2, RS#3, RS#4, and RS#5. In the currently obtained beam measurement results, the RSs are sorted in descending order of channel measurement parameters as follows: RS#4, RS#1, RS#2, RS#3, and RS#5. Assume w is 3. Since the first 3 RSs have changed in the sorting results of the two times before and after, the above preset condition is satisfied. At this time, the terminal can send a beam measurement report to the access network device. The beam measurement report may include indication information of the channel measurement parameters corresponding to each RS (that is, RS#1, RS#2, and RS#3) in the target RS set, and may also include indication information of the channel measurement parameters corresponding to RS#4.

[0138] When the beam measurement results meet this preset condition, it indicates that the sorting of several RSs with larger channel measurement parameters has changed. At this time, the terminal sends a beam measurement report to the access network device so that the access network device can update the target TCI state set according to the beam measurement report. For example, add the TCI state corresponding to the RS with a larger channel measurement parameter to the target TCI state set, and delete the TCI state corresponding to the RS with a smaller channel measurement parameter from the target TCI state set.

[0139] 2. There is at least one RS in the target RS set whose corresponding channel measurement parameter is less than the first threshold;

[0140] Among them, the first threshold can be preset, such as configured by the access network device or specified in advance by the protocol. The embodiments of the present disclosure do not limit this.

[0141] For example, the target RS set includes the following RSs: RS#1, RS#2, and RS#3, and the type of the channel measurement parameter is L1-RSRP. Assume that the L1-RSRP corresponding to RS#1 is less than the first threshold, and the L1-RSRPs corresponding to RS#2 and RS#3 are not less than the first threshold. In this case, the beam measurement results meet the above preset condition. At this time, the terminal can send a beam measurement report to the access network device. The beam measurement report may include indication information of the L1-RSRPs corresponding to each RS (that is, RS#1, RS#2, and RS#3) in the target RS set respectively.

[0142] When the beam measurement result meets this preset condition, it indicates that there is a TCI state corresponding to an RS with a relatively small channel measurement parameter in the target TCI state set. At this time, the terminal sends a beam measurement report to the access network device so that the access network device can update the target TCI state set according to the beam measurement report. For example, delete the TCI state corresponding to the RS with a relatively small channel measurement parameter from the target TCI state set.

[0143] 3. The sum of the channel measurement parameters corresponding to at least one RS in the target RS set and a preset offset value is less than the maximum value of the channel measurement parameters corresponding to m other RSs.

[0144] Among them, the preset offset value can be preset in advance. For example, it can be configured by the access network device or stipulated in advance by the protocol. The embodiments of the present disclosure do not limit this. Optionally, the preset offset value is greater than 0.

[0145] For example, the target RS set includes the following RSs: RS#1, RS#2, and RS#3, and the other RSs include RS#4 and RS#5. The type of the channel measurement parameter is L1-RSRP. Assume that the maximum value of the L1-RSRP corresponding to the other RSs is the L1-RSRP corresponding to RS#5, and the sum of the L1-RSRP corresponding to RS#2 and the preset offset value is less than the L1-RSRP corresponding to RS#5. Therefore, the above preset condition is met. At this time, the terminal can send a beam measurement report to the access network device. The beam measurement report may include indication information of the L1-RSRP corresponding to each RS (that is, RS#1, RS#2, and RS#3) in the target RS set, and may also include indication information of the L1-RSRP corresponding to RS#5.

[0146] When the beam measurement result meets this preset condition, it indicates that there is a TCI state corresponding to an RS with a relatively small channel measurement parameter in the target TCI state set, and there is also a TCI state corresponding to another RS with a relatively large channel measurement parameter. At this time, the terminal sends a beam measurement report to the access network device so that the access network device can update the target TCI state set according to the beam measurement report. For example, add the TCI state corresponding to the other RS with a relatively large channel measurement parameter to the target TCI state set, and delete the TCI state corresponding to the RS with a relatively small channel measurement parameter from the target TCI state set.

[0147] 4. There is at least one other RS among the m other RSs whose corresponding channel measurement parameter is greater than a second threshold value.

[0148] Among them, the second threshold value can be preset in advance. For example, it can be configured by the access network device or stipulated in advance by the protocol. The embodiments of the present disclosure do not limit this.

[0149] For example, other RSs include RS#4 and RS#5, and the type of the channel measurement parameter is L1-RSRP. Assume that the L1-RSRP corresponding to RS#4 is greater than the second threshold, and the L1-RSRP corresponding to RS#5 is not greater than the second threshold. In this case, the beam measurement result meets the above preset condition. At this time, the terminal can send a beam measurement report to the access network device, and the beam measurement report may include indication information of the L1-RSRP corresponding to each RS in the target RS set, and indication information of the L1-RSRP corresponding to RS#4.

[0150] When the beam measurement result meets this preset condition, it indicates that there is a TCI state corresponding to another RS with a relatively large channel measurement parameter. At this time, the terminal sends a beam measurement report to the access network device so that the access network device can update the target TCI state set according to the beam measurement report, such as adding the TCI state corresponding to the other RS with a relatively large channel measurement parameter to the target TCI state set.

[0151] 5. There is at least one RS in the target RS set whose corresponding channel measurement parameter is less than the third threshold, and there is at least one other RS among the m other RSs whose corresponding channel measurement parameter is greater than the fourth threshold.

[0152] Among them, the third threshold and the fourth threshold can be preset, such as configured by the access network device or pre-specified by the protocol. The embodiments of the present disclosure do not limit this.

[0153] For example, the target RS set includes the following RSs: RS#1, RS#2, and RS#3, other RSs include RS#4 and RS#5, and the type of the channel measurement parameter is L1-RSRP. Assume that the L1-RSRP corresponding to RS#2 is less than the third threshold, and the L1-RSRP corresponding to RS#5 is greater than the fourth threshold, so the above preset condition is met. At this time, the terminal can send a beam measurement report to the access network device, and the beam measurement report may include indication information of the L1-RSRP corresponding to each RS (i.e., RS#1, RS#2, and RS#3) in the target RS set, and may also include indication information of the L1-RSRP corresponding to RS#5.

[0154] When the beam measurement result meets this preset condition, it indicates that there is a TCI state corresponding to an RS with a relatively small channel measurement parameter in the target TCI state set, and there is a TCI state corresponding to another RS with a relatively large channel measurement parameter. At this time, the terminal sends a beam measurement report to the access network device so that the access network device can update the target TCI state set according to the beam measurement report, such as adding the TCI state corresponding to the other RS with a relatively large channel measurement parameter to the target TCI state set, and deleting the TCI state corresponding to the RS with a relatively small channel measurement parameter from the target TCI state set.

[0155] In the embodiments of the present disclosure, the indication information of the channel measurement parameters corresponding to the RS can be used to represent the magnitude of the channel measurement parameters. In one example, the indication information of the channel measurement parameters corresponding to k RSs in the beam measurement report can be represented in the following manner: among the k RSs, the indication information of the channel measurement parameters corresponding to the optimal RS is represented by a bits, where the optimal RS is the RS with the largest channel measurement parameters among the k RSs, and a is a positive integer; among the k RSs, the indication information of the channel measurement parameters corresponding to each remaining RS except the optimal RS is represented by b bits, where b is a positive integer. Optionally, the above a bits are used to represent the absolute value of the channel measurement parameters corresponding to the optimal RS. In addition, the indication information of the channel measurement parameters corresponding to the i-th remaining RS is used to indicate the difference between the channel measurement parameters corresponding to the i-th remaining RS and the channel measurement parameters corresponding to the optimal RS, where i is a positive integer. The values of a and b above can be set according to the type of the channel measurement parameters and their corresponding value ranges. For example, when the channel measurement parameter is L1-RSRP, a = 7 and b = 4.

[0156] Optionally, among the multiple different sequences formed by the above b bits, a specified sequence is selected to indicate that the channel measurement parameters corresponding to the RS are less than a preset threshold. For example, when b = 4, 16 different sequences can be formed. Assume that "0000" is selected to indicate that the channel measurement parameters corresponding to the RS are less than the preset threshold. When the channel measurement parameters corresponding to a certain RS are less than the preset threshold, it indicates that the beam corresponding to the RS has a beam failure. The preset threshold can be set according to the type of the channel measurement parameters. For example, when the channel measurement parameter is L1-RSRP, the preset threshold is set to -140 dB. In this way, when the access network device finds from the beam measurement report that the indication information of the channel measurement parameters corresponding to a certain RS is represented by the specified sequence, it can know that the beam corresponding to the RS has a beam failure. Subsequently, the access network device can delete the TCI state corresponding to the RS from the target TCI state set.

[0157] Optionally, the beam measurement report further includes parameter type indication information. If there are multiple different types of channel measurement parameters for the terminal to select, the terminal can add parameter type indication information in the beam measurement report to indicate the type of the channel measurement parameters.

[0158] In step 203, the access network device updates the target TCI state set according to the beam measurement report.

[0159] In one example, the access network device adds at least one TCI state to the target TCI state set and / or deletes at least one TCI state from the target TCI state set; wherein, the channel measurement parameter of the RS corresponding to the TCI state added to the target TCI state set is greater than the channel measurement parameter of the RS corresponding to the TCI state deleted from the target TCI state set.

[0160] Exemplarily, assume that in the beam measurement report received by the access network device, it includes the indication information of the channel measurement parameters corresponding to each RS (such as RS#1, RS#2, and RS#3) included in the target RS set, and the indication information of the channel measurement parameters corresponding to at least one other RS (such as RS#4). If the access network device determines according to the above information that the channel measurement parameter of RS#4 is greater than the channel measurement parameter of RS#2, the access network device can delete the TCI state corresponding to RS#2 from the target TCI state set and add the TCI state corresponding to RS#4 to the target TCI state set.

[0161] In step 204, the access network device sends TCI state update information to the terminal.

[0162] The TCI state update information is used to indicate the TCI states included in the updated target TCI state set.

[0163] In one example, the TCI state update information includes the identification information of the RS corresponding to each TCI state in the updated target TCI state set.

[0164] In another example, the TCI state update information includes an addition indication information and / or a deletion indication information, wherein the addition indication information is used to indicate the TCI states that need to be added to the target TCI state set, and the deletion indication information is used to indicate the TCI states that need to be deleted from the target TCI state set.

[0165] Optionally, the access network device sends the TCI state update information to the terminal through RRC signaling. Correspondingly, the terminal receives the TCI state update information sent by the access network device and updates the target TCI state set according to the TCI state update information.

[0166] In summary, in the technical solution provided by the embodiments of the present disclosure, by the terminal obtaining the beam measurement result and only sending the beam measurement report to the access network device when the terminal detects that the beam measurement result meets the preset condition, compared with the terminal sending the beam measurement report to the access network device in a periodic, aperiodic or semi-static manner, the technical solution provided by the embodiments of the present disclosure overcomes the problems of untimely reporting and a large number of unnecessary reports, and the timing of the terminal sending the beam measurement report is reasonable and accurate.

[0167] In addition, when the terminal detects that the beam measurement result meets a preset condition, it sends a beam measurement report to the access network device, enabling the access network device to update the TCI state set in a timely manner according to the beam measurement report, ensuring that the terminal selects an appropriate beam for downlink reception.

[0212] Figure 5 It is a schematic structural diagram of an access network device shown according to an exemplary embodiment.

[0213] The access network device 500 includes a transmitter / receiver 501 and a processor 502. Among them, the processor 502 can also be a controller, Figure 5 which is denoted as "controller / processor 502" in the figure. The transmitter / receiver 501 is used to support the access network device to send and receive information with the terminal in the above embodiment, and to support the access network device to communicate with other network entities. The processor 502 performs various functions for communicating with the terminal. In the uplink, the uplink signal from the terminal is received via the antenna, demodulated by the receiver 501 (for example, demodulating the high-frequency signal into a baseband signal), and further processed by the processor 502 to recover the service data and signaling messages sent by the terminal. In the downlink, the service data and signaling messages are processed by the processor 502, and modulated by the transmitter 501 (for example, modulating the baseband signal into a high-frequency signal) to generate a downlink signal, which is then transmitted to the terminal via the antenna. It should be noted that the above demodulation or modulation functions can also be completed by the processor 502. For example, the processor 502 is also used to execute each step on the access network device side in the above method embodiment, and / or other steps of the technical solution described in the embodiments of the present disclosure.

[0214] Furthermore, the access network device 500 may further include a memory 503 for storing program codes and data of the access network device 500. In addition, the access network device 500 may further include a communication unit 504. The communication unit 504 is used to support the access network device 500 to communicate with other network entities (such as network devices in the core network, etc.). For example, in a 5G NR system, the communication unit 504 may be an NG-U interface for supporting the access network device 500 to communicate with a UPF (User Plane Function) entity; or the communication unit 504 may also be an NG-C interface for supporting the access network device 500 to communicate with an AMF (Access and Mobility Management Function) entity.

[0215] It can be understood that Figure 5 only a simplified design of the access network device 500 is shown. In practical applications, the access network device 500 may include any number of transmitters, receivers, processors, controllers, memories, communication units, etc., and all access network devices that can implement the embodiments of the present disclosure are within the protection scope of the embodiments of the present disclosure.

[0216] Figure 6 is a schematic structural diagram of a terminal shown according to an exemplary embodiment.

[0217] The terminal 600 includes a transmitter 601, a receiver 602, and a processor 603. Among them, the processor 603 may also be a controller, Figure 6 denoted as "controller / processor 603" in. Optionally, the terminal 600 may further include a modulation and demodulation processor 605, where the modulation and demodulation processor 605 may include an encoder 606, a modulator 607, a decoder 608, and a demodulator 609.

[0218] In one example, the transmitter 601 adjusts (e.g., analog-to-digital conversion, filtering, amplification, up-conversion, etc.) the output samples and generates an uplink signal, which is transmitted via the antenna to the access network device described in the above embodiments. On the downlink, the antenna receives the downlink signal transmitted by the access network device in the above embodiments. The receiver 602 adjusts (e.g., filtering, amplification, down-conversion, and digitization, etc.) the signal received from the antenna and provides input samples. In the modulation and demodulation processor 605, the encoder 606 receives the service data and signaling messages to be transmitted on the uplink, and processes (e.g., formats, encodes, and interleaves) the service data and signaling messages. The modulator 607 further processes (e.g., symbol mapping and modulation) the encoded service data and signaling messages and provides output samples. The demodulator 609 processes (e.g., demodulates) the input samples and provides symbol estimates. The decoder 608 processes (e.g., de-interleaves and decodes) the symbol estimates and provides the decoded data and signaling messages sent to the terminal 600. The encoder 606, modulator 607, demodulator 609, and decoder 608 may be implemented by the integrated modulation and demodulation processor 605. These units process according to the radio access technology adopted by the radio access network (e.g., access technologies of LTE and other evolved systems). It should be noted that when the terminal 600 does not include the modulation and demodulation processor 605, the above functions of the modulation and demodulation processor 605 can also be completed by the processor 603.
