In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
fig. 1 is a flowchart of a method for transmitting a transmission bandwidth of a control channel according to an embodiment of the present invention.
the transmission bandwidth transmitting method of the control channel may be used on the base station side, that is, the base station may perform each step shown in fig. 1.
the method for transmitting the transmission bandwidth of the control channel may specifically include the following steps:
Step S101: configuring network configuration information, wherein the network configuration information comprises a resource position of a first control resource set and a resource position of a second control resource set;
step S102: and sending the network configuration information to enable the user equipment to determine the transmission bandwidth of the control channel associated with the first control resource set and/or the transmission bandwidth of the control channel associated with the second control resource set according to the network configuration information.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.
The control resource set in this embodiment may be used at least to provide frequency domain resources for the control channel. Specifically, the control resource set may be a control resource set (CORSET). More specifically, the first set of control resources may be a set of control resources CORSET0, and the second set of control resources may be other CORSET besides CORSET0, such as CORSET1, CORSET2, and the like.
It should be noted that the control resource set may also be any other practicable name, and the embodiment of the present invention is not limited thereto.
The transmission bandwidth of the control channel in the embodiment of the present invention may refer to a position of the DFT output or the IDFT input mapped in the frequency domain.
in the specific implementation of step S101, the base station may configure at least the frequency domain resource location of the first control resource set and the frequency domain resource location of the second control resource set in the network configuration information. The frequency domain resource location of the first control resource set may represent a specific location of the resource occupied by the first control resource set in the frequency domain, for example, the frequency domain resource location may include a frequency domain starting point and a frequency domain ending point. Similarly, the frequency domain resource location of the second set of control resources can represent a specific location of the second set of control resources in the frequency domain.
Further, in the implementation of step S102, the base station may send out the network configuration information. After receiving the network configuration information, a User Equipment (UE) may determine, according to the network configuration information, a transmission bandwidth of a control channel associated with the first control resource set and/or a transmission bandwidth of a control channel associated with the second control resource set.
That is to say, the transmission bandwidth of the control channel and the frequency domain resource location of the first control resource set and/or the frequency domain resource location of the second control resource set have a preset mapping relationship, for example, the transmission bandwidth of the control channel is the frequency domain resource bandwidth of the first control resource set, and the UE may determine the transmission bandwidth of the control channel associated with the first control resource set and/or the transmission bandwidth of the control channel associated with the second control resource set according to the preset mapping relationship and the network configuration information. The preset mapping relationship may be agreed in advance by a communication standard protocol, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the base station may configure, in the network configuration information, the frequency domain resource location of the first control resource set and the frequency domain resource location of the second control resource set, and the user equipment may determine the transmission bandwidth based on the network configuration information, that is, at least based on the frequency domain resource location of the first control resource set and/or the frequency domain resource location of the second control resource set, so as to monitor the control channel or decode the control information.
in one non-limiting embodiment of the present invention, step S102 shown in fig. 1 may include the following steps: sending the network configuration information in a broadcasting mode; or, the network configuration information is carried in a high-level signaling and sent out.
In this embodiment, the base station may send the network configuration information to the UE in a broadcast manner or a high-level signaling. Specifically, the frequency domain resource position of the first control resource set may be sent out in a broadcast manner or by a high-level signaling; the frequency domain resource locations of the second set of control resources may be sent via higher layer signaling.
more specifically, the higher layer signaling may be UE-specific (UE-specific) higher layer signaling.
In a non-limiting embodiment of the present invention, in a transmission time unit in which the first control resource set is located, a transmission bandwidth of a control channel associated with the first control resource set is a frequency domain resource bandwidth of the first control resource set, and a transmission bandwidth of a control channel associated with the second control resource set is a frequency domain resource bandwidth of the first control resource set; and in a transmission time unit where the first control resource set is not located, the transmission bandwidth of the control channel associated with the second control resource set is the frequency domain resource bandwidth of the second control resource set.
The control channel referred to in this embodiment may be a control channel associated with a first control resource set, or may be a control channel associated with a second control resource set. The transmission bandwidth of the control channel may be different in different transmission time units.
According to the embodiment of the invention, the transmission bandwidths of the control channels are different according to different transmission time units, specifically, the transmission bandwidths of the control channels can be the frequency domain resource bandwidth of the first control resource set or the frequency domain resource bandwidth of the second control resource set, so that the flexibility of the transmission bandwidth of the control channels is realized.
The term transmission time unit in this embodiment may refer to a length of independently decoded transmission in a wireless link, or a transmission time interval, or a scheduling unit. The transmission time unit may also be any other practicable name, and the embodiment of the present invention is not limited thereto.
further, the transmission time unit may be selected from a time unit set in which a small slot (mini-slot), a sub-slot (sub-slot), a slot (slot), a subframe (subframe), a radio frame, and a synchronization information block are located.
In a non-limiting embodiment of the present invention, the network configuration information further includes a length of a transmission bandwidth.
In this embodiment, after the network configuration information includes the length of the transmission bandwidth, the specific frequency domain position of the transmission bandwidth may be obtained as long as the frequency domain starting point or the frequency domain ending point of the transmission bandwidth is obtained, that is, the frequency domain starting point or the frequency domain ending point of the transmission bandwidth may be the frequency domain starting point or the frequency domain ending point of the first control resource set. Flexibility in transmission bandwidth of the control channel is achieved.
In a specific implementation, after receiving the network configuration information from the base station, the UE may determine a specific frequency domain position of the control channel according to the length of the transmission bandwidth of the control channel in the network configuration information, the frequency domain resource position of the first control resource set, and/or the second control resource set. For example, the transmission bandwidth of the control channel may be a frequency domain resource having a length of the transmission bandwidth starting from a frequency domain start point of the first control resource set or a frequency domain resource having a length of the transmission bandwidth ending from a frequency domain end point of the first control resource set.
Further, the length of the transmission bandwidth refers to the length of the transmission bandwidth of the control channel in the transmission time unit.
In one non-limiting embodiment of the present invention, the frequency domain resource locations of the first set of control resources and the frequency domain resource locations of the second set of control resources do not partially overlap.
That is, the relationship between the frequency domain resource locations of the first control resource set and the frequency domain resource locations of the second control resource set may be completely overlapped, completely non-overlapped, or contain a relationship, so as to avoid a situation that the control channel associated with the first control resource set or the control channel associated with the second control resource set cannot be demodulated, so as to ensure that both the control channel associated with the first control resource set and the control channel associated with the second control resource set can be demodulated.
Further, the UE does not demodulate a control channel associated with the second control resource set if the frequency domain resource locations of the first control resource set and the second control resource set partially overlap.
Referring to fig. 2, the method for acquiring the transmission bandwidth of the control channel shown in fig. 2 may be used at the user equipment side, that is, the UE may perform the steps shown in fig. 2.
The method for acquiring the transmission bandwidth of the control channel may include the steps of:
Step S201: receiving network configuration information, wherein the network configuration information comprises a resource position of a first control resource set and a resource position of a second control resource set;
Step S202: and determining the transmission bandwidth of the control channel associated with the first control resource set and/or the transmission bandwidth of the control channel associated with the second control resource set according to the network configuration information.
In this embodiment, the UE may receive network configuration information from the base station. The network configuration information may be obtained in broadcast information, or may be obtained in higher layer signaling.
The UE may determine, according to the frequency domain resource location of the first control resource set and/or the frequency domain resource location of the second control resource set in the network configuration information, a transmission bandwidth of a control channel associated with the first control resource set and/or a transmission bandwidth of a control channel associated with the second control resource set.
In a non-limiting embodiment of the present invention, referring to fig. 3, step S202 shown in fig. 2 may include the following steps:
Step S301: determining, in a transmission time unit in which the first control resource set is located, that a transmission bandwidth of a control channel associated with the first control resource set is a frequency domain resource bandwidth of the first control resource set;
Step S302: determining, in a transmission time unit in which the first control resource set is located, that a transmission bandwidth of a control channel associated with the second control resource set is a frequency domain resource bandwidth of the first control resource set;
Step S303: and in a transmission time unit where the first control resource set is not located, determining that the transmission bandwidth of the control channel associated with the second control resource set is the frequency domain resource bandwidth of the second control resource set.
In an actual application scenario, one or more of steps S301 to S303 may be selectively performed.
In a specific implementation, the UE may determine the transmission bandwidth of the control channel of the control resource set according to the transmission time unit of the control resource set. Wherein the transmission time unit is selected from a time unit set in which a small time slot, a sub-time slot, a sub-frame, a radio frame and a synchronization information block are located.
in the embodiment of the present invention, the transmission bandwidths of the control channels are different according to different transmission time units, and specifically, the transmission bandwidths of the control channels may be frequency domain resource bandwidths of a first control resource set or frequency domain resource bandwidths of a second control resource set, so as to implement flexibility of the transmission bandwidths of the control channels.
In one non-limiting embodiment of the present invention, step S202 shown in fig. 2 may include the following steps: determining a frequency domain starting point of the first set of control resources as a frequency domain starting point of the transmission bandwidth; and determining the frequency domain position of the transmission bandwidth of the control channel associated with the first control resource set and/or the transmission bandwidth of the control channel associated with the second control resource set according to the frequency domain starting point of the transmission bandwidth and the length of the transmission bandwidth in the network configuration information.
In this embodiment, the UE may determine that the frequency domain starting point of the first control resource set is the frequency domain starting point of the transmission bandwidth, and then may determine the frequency domain position of the transmission bandwidth according to the length of the transmission bandwidth in the network configuration information.
In one non-limiting embodiment of the present invention, step S202 shown in fig. 2 may include the following steps: determining a frequency domain endpoint of the first control resource set as a frequency domain endpoint of the transmission bandwidth; and determining the frequency domain position of the transmission bandwidth of the control channel associated with the first control resource set and/or the transmission bandwidth of the control channel associated with the second control resource set according to the frequency domain end point of the transmission bandwidth and the length of the transmission bandwidth in the network configuration information.
Unlike the previous embodiments, the UE may determine the frequency domain end point of the first set of control resources as the frequency domain end point of the transmission bandwidth.
It should be noted that, regarding that the frequency domain starting point of the first control resource set as the frequency domain starting point of the transmission bandwidth, or the frequency domain ending point of the first control resource set as the frequency domain ending point of the transmission bandwidth, may be agreed by a communication standard protocol, and the embodiment of the present invention is not limited thereto.
in a non-limiting embodiment of the present invention, the method for acquiring the transmission bandwidth of the control channel may further include the following steps: demodulating a control channel associated with the first control resource set using only a transmission bandwidth of the control channel if the frequency domain resource locations of the first control resource set and the second control resource set partially overlap.
In this embodiment, since the frequency domain resource positions of the first control resource set and the second control resource set are partially overlapped, the control channel associated with the first control resource set or the second control resource set cannot be demodulated, so that the UE may demodulate only the control channel associated with the first control resource set, that is, demodulate only the control channel associated with the first control resource set by using the transmission bandwidth of the control channel.
