A Terminal may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), and so on, for example, the Terminal may be a Mobile phone (or referred to as a "cellular" phone), a computer with a Mobile Terminal, and so on, and for example, the Terminal may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted Mobile device. The base station may have a processor disposed therein, and a transceiver, the processor may be configured to detect paging trigger events and control the transceiver to receive and transmit data. A memory may also be provided which may be used to store data required and generated by the base station during the processing described below. The terminal may have a processor disposed therein that may be configured to determine the processing associated with the first beam, and a transceiver configured to receive and transmit data. A memory may also be provided which may be used to store data required and generated by the terminal during the processes described below.
The process flow shown in fig. 1 will be described in detail below with reference to the embodiments, and the contents may be as follows:
in step 101, the base station transmits a first system message to the terminal through a plurality of beams.
In implementation, in order to save the power of the terminal, for a terminal without data interaction, the base station may configure the terminal so that the terminal monitors information sent by the base station only at the configured time. In this case, when the base station needs to send downlink data to the terminal, paging information may be sent to the terminal in the dormant state, and in this case, the paging information may be used to trigger the terminal to initiate a connection process with the base station to enter a connection state, and the paging information may include a terminal identifier of the terminal. In addition, when the system information changes, the base station may also send paging information to each terminal in the cell covered by the base station, in this case, the paging information may include system information change indication information, and after the base station sends the paging information to the terminal, the terminal may update the system information at a corresponding location.
In the embodiment of the invention, before the base station sends the paging information to the terminal, the beam identifier of the optimal beam corresponding to the terminal can be determined. Specifically, in the working process of the base station and the terminal, the base station often sends a system message (may be referred to as a first system message) to the terminal, as shown in fig. 2, where the first system message may be any one of all system messages sent by the base station to the terminal, may be a system message sent by the base station through multiple beams (where the coverage range corresponding to each beam is different), for example, may be a message including the system message, or a system message carrying paging indication information, and the like, and the embodiment of the present invention does not limit the system message.
Optionally, the first system message may be a system message carrying paging indication information, and correspondingly, the processing procedure in step 101 may be as follows: and sending a first system message carrying paging indication information to the terminal through a plurality of wave beams.
In practice, before sending paging information to the terminal, paging indication information is often sent to the terminal. Specifically, when the base station needs to send the paging indication information to the terminal, the base station may send the system message carrying the paging indication information to the terminal through a plurality of beams, that is, the first system message may be the system message carrying the paging indication information. The paging indication information may be carried in a common channel; or, the paging indication information may be carried in the scheduling instruction; alternatively, the paging indication information may be carried on a terminal-specific UE-specific channel.
Optionally, the first system message may carry a terminal identifier, where the terminal identifier carried in the first system message may be a terminal identifier of a terminal that is to receive the paging indication information. Specifically, when the base station needs to send downlink data to the terminal, it may be determined whether the terminal is currently in a dormant state, and if the terminal is currently in the dormant state, the base station may send a first system message carrying paging indication information to the terminal, and may send the first system message through a plurality of beams, where in this case, the first system message may carry a terminal identifier of the terminal that is to receive the paging indication information. In addition, the first system message may not carry the terminal identifier. Specifically, when the system information changes, the base station may send a first system message carrying paging indication information to each terminal in a cell covered by the base station, and may send the first system message through a plurality of beams, where in this case, the first system message may not carry a terminal identifier.
Optionally, the base station may further send channel configuration information to the terminal, so that the terminal may send the first beam identifier through a channel corresponding to the channel configuration information, and accordingly, the processing procedure may be as follows: and sending a second system message carrying channel configuration information to the terminal, wherein the channel configuration information comprises a time-frequency resource position of a channel used for the terminal to send the first beam identifier.
In implementation, the base station may further send channel configuration information to the terminal, where the channel configuration information may include a time-frequency resource location, transmission format information, and the like of a channel, and the channel may be a channel used for the terminal to send the first beam identifier. Specifically, the base station may carry the system message (may be referred to as a second system message) in the second system message when sending the system message to the terminal. The second system message may be a message including system information, radio resource connection RRC signaling, medium access control MAC control element CE, or physical layer signaling.
In step 102, the terminal receives a first system message transmitted by the base station through at least one beam.
In an implementation, after the base station transmits the first system message to the terminal through the multiple beams, when the terminal is in a coverage area of some of the multiple beams, the first system message transmitted by the base station through the several beams may be received, that is, after the base station transmits the first system message through the multiple beams, the terminal may receive the first system message transmitted by the base station through at least one of the multiple beams.
Optionally, for a case that the first system message is a system message carrying paging indication information, correspondingly, the processing procedure in step 102 may be as follows: and receiving a first system message which is sent by the base station through at least one wave beam and carries paging indication information.
In step 103, the terminal determines an optimal first beam among the at least one beam, where the optimal first beam may be the first beam with the largest received signal strength.
In implementation, after receiving a first system message transmitted by a base station through at least one beam, a terminal may determine an optimal first beam. Specifically, the terminal may select, according to the received signal strength corresponding to at least one beam, a beam (which may be referred to as a first beam) with the largest received signal strength among the at least one beam.
Optionally, for a situation that the first system message carrying the paging indication information carries the terminal identifier, correspondingly, the processing procedure in step 103 may be as follows: and if the terminal identifier carried in the first system message is detected to be the terminal identifier of the local terminal, determining a first beam with the maximum received signal strength in at least one beam.
In implementation, for a situation that a first system message carrying paging indication information carries a terminal identifier, after receiving the first system message, a terminal may detect whether the terminal identifier carried in the first system message is a terminal identifier of a local terminal, and if it is detected that the terminal identifier carried in the first system message is the terminal identifier of the local terminal, may determine, in at least one received beam, a first beam with a maximum received signal strength. If it is detected that the terminal identifier carried in the first system message is not the terminal identifier of the terminal, the terminal may not perform the process of determining the first beam. In addition, for the condition that the first system message carrying the paging indication information does not carry the terminal identifier, after receiving the first system message, the terminal may not detect the terminal identifier, but directly determine the first beam with the maximum received signal strength in at least one beam. That is to say, when the first system message carries the terminal identifier, only the terminal corresponding to the terminal identifier is in at least one beam to determine the first beam with the maximum received signal strength, and when the first system message does not carry the terminal identifier, each terminal receiving the first system message may determine the first beam with the maximum received signal strength in at least one beam.
Optionally, when the first system message is not a system message carrying paging indication information, the first system message may also be a system message whose time-frequency resource location is near the time-frequency resource location of the paging indication information, and correspondingly, the processing procedure in step 103 may be as follows: and if the distance between the time-frequency resource position of the first system message and the time-frequency resource position of the paging indication information sent by the base station is within a preset range, determining a first beam with the maximum received signal strength in at least one beam.
In implementation, after receiving the first system message, the terminal may compare the time-frequency resource location of the first system message with the time-frequency resource location of the paging indicator information, if the time-frequency resource location of the first system message is near the time-frequency resource location of the paging indication information sent by the base station to the terminal, the terminal may determine, among the at least one beam, the first beam having the greatest received signal strength, or, if the distance between the time-frequency resource location of the first system message and the time-frequency resource location of the paging indication message sent by the base station is within the preset range and the first beam is not determined currently, the terminal may determine, among the at least one beam, the first beam having the greatest received signal strength, that is, the first system message may be a system message in which the distance between the time-frequency resource location and the time-frequency resource location of the paging indication information sent by the base station to the terminal is within a preset range. For example, when the time-frequency resource location of the system message carrying the signal for initial access is near the time-frequency resource location of the paging indication information, the terminal may determine the first beam by detecting the received signal strength of the system message carrying the signal for initial access, which is sent by the base station through different beams. In addition, after receiving the first system message, the terminal may further perform the following processing: and if the time domain resource position of the first system message is closest to the time domain resource position of the paging indication information sent by the base station, determining a first beam with the maximum received signal strength in at least one beam. That is, the first system message may be a system message whose time domain resource location is closest to the time domain resource location of the paging indicator information. The time-frequency resource position of the paging indication information may be notified to the terminal by the base station through a message including system information, or radio resource connection RRC signaling, or medium access control MAC control element CE, or physical layer signaling, or determined by the terminal after receiving the paging indication information.
Optionally, after receiving the first system message, the terminal may determine whether the terminal is in a sleep state, and correspondingly, the processing procedure in step 103 may be as follows: and if the terminal is in the dormant state, determining a first beam with the maximum received signal strength in at least one beam.
In implementation, after receiving the first system message, the terminal may determine whether the terminal is currently in a sleep state, determine, if the terminal is in the sleep state, a first beam with a maximum received signal strength among the at least one beam, and if the terminal is not in the sleep state, the terminal may not perform the process of determining the first beam.
In step 104, the terminal transmits a first beam identification of the first beam to the base station.
In implementation, after determining the first beam, the terminal may send a first beam identifier of the first beam to the base station, where the terminal may carry the terminal identifier of the terminal when sending the first beam identifier to the base station.
Optionally, for a case that the terminal determines the first beam in the sleep state, correspondingly, the processing procedure in step 104 may be as follows: a forward pilot signal including a first beam identification of the first beam is transmitted to the base station.
In implementation, after the terminal receives the paging indication information, if the terminal is currently in a dormant state, the terminal often sends a forward pilot signal preamble to the base station, and in this case, after determining the first beam, the terminal can send the first beam identifier of the first beam to the base station through the forward pilot signal, that is, the terminal can send the forward pilot signal including the first beam identifier of the first beam to the base station. Specifically, the terminal may perform scrambling processing on the forward pilot signal (where the forward pilot signal is a digital signal), that is, the terminal identifier and the first beam identifier are implicitly carried in the scrambled forward pilot signal. In addition, the first beam identifier and the terminal identifier may also be explicitly carried, that is, an information field may be added to the forward pilot signal, so that the terminal may add the first beam identifier and the terminal identifier to the newly added information field, or may adopt an implicit method and an explicit method in combination. The time-frequency position of the forward pilot frequency can be predefined or the base station sends to the terminal through system information, RRC signaling, MAC CE or physical layer signaling.
Optionally, the terminal may further send the first beam identifier through a channel configured by the base station, and accordingly, the processing procedure may be as follows: and receiving a second system message which is sent by the base station and carries channel configuration information, wherein the channel configuration information comprises a time-frequency resource position of a channel used for the terminal to send the first beam identifier. Accordingly, the process of step 104 may be as follows: and sending a first beam identifier of the first beam to the base station through a channel corresponding to the time-frequency resource position.
In implementation, after the base station sends the second system message carrying the channel configuration information to the terminal, the terminal may receive the second system message carrying the channel configuration information sent by the base station, and further, after the first beam is determined, the beam identifier of the first beam may be sent to the base station through a channel corresponding to the time-frequency resource location configured by the base station.
Alternatively, the second system message may be a message including system information, radio resource connection RRC signaling, medium access control MAC control element CE, or physical layer signaling.
In step 105, the base station receives a first beam identifier transmitted by the terminal.
In an implementation, after the terminal transmits the first beam identifier to the base station, the base station may receive the first beam identifier transmitted by the terminal. After receiving the first beam identifier sent by the terminal, the base station may store the first beam identifier.
