Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a resource configuration method, a base station and a terminal, aiming at the problems that the prior art has no configuration scheme aiming at BWP, the communication flow is incomplete, and the reliability of network communication cannot be ensured.
As shown in fig. 1, an embodiment of the present invention provides a resource allocation method, applied to a base station, including:
step 101, sending the configuration information of the bandwidth part BWP to the terminal.
Wherein the configuration information includes: at least one of BWP identification information, BWP uplink and downlink indication information, BWP type information, BWP logical channel LCH information, terminal BWP available allocation information, and BWP frequency domain location (the frequency domain location indicates which frequency band the BWP belongs to in the frequency domain);
wherein the uplink and downlink indication information of the BWP includes: BWP identification information for uplink and/or downlink, the BWP type information including: at least one of a main BWP of the terminal, a secondary BWP of the terminal, and a BWP without distinguishing between main and secondary BWPs, it should be noted that the base station may configure 3 types of BWPs to the terminal, which are the main BWP, the secondary BWP, and the general BWP (i.e. the BWP without distinguishing between main and secondary BWPs), and the base station may configure a plurality of secondary BWPs (sbwpps), where the secondary BWP may be configured for deactivation, and the main BWP (pbwp) may not be configured for deactivation after activation.
It should be noted that the allocation information of the available BWP of the terminal refers to uplink and downlink BWP information allocated to the terminal by the base station, and since the allocation information of the available BWP of the terminal refers to that the uplink BWP and the downlink BWP must be configured to the terminal at the same time, the allocation information herein can also be considered as the association information of the uplink BWP and the downlink BWP configured for the terminal, for example, as shown in fig. 2, there are BWP1, BWP2 and BWP3 in Uplink (UL), and BWP1, BWP2, BWP3, BWP4 and BWP5 in Downlink (DL), where BWP1 is PBWP, BWP3 and BWP5 are sbwpps, and the base station assigns the association information: the uplink BWP2 and the downlink BWP1, BWP3 and BWP5 are assigned to the terminal as the available BWP for the terminal.
Specifically, the implementation manner of step 101 is: sending the configuration information to a terminal through a preset message;
wherein the preset message comprises: at least one of a Media Access Control (MAC) layer Control Element (CE), a Radio Resource Control (RRC) message, Packet Data Convergence Protocol (PDCP) control signaling, physical layer indication signaling, and a system message.
It should be noted that the base station may also select to use different preset messages to send different contents in the configuration information, and optionally, if the configuration information includes BWP identification information and/or allocation information of available BWPs of the terminal, send the BWP identification information and/or the allocation information of available BWPs of the terminal to the terminal through a system message;
wherein the system message comprises: at least one of a Master Information Block (MIB), a system message block (SIB), and a preset system message, wherein the preset system message is a part of the system message for transmitting information based on a terminal request.
Optionally, if the configuration information includes allocation information of the available BWP of the terminal, sending the allocation information of the available BWP of the terminal to the terminal through an RRC message;
wherein the RRC message comprises: at least one of the second message, the fourth message, and the RRC reconfiguration message.
It should be noted that the second message is a random access Response (RACH Response) message, the fourth message is an RRC Connection configuration (RRC Connection Setup) message, and the RRC reconfiguration message may be a handover command (HO CMD).
When the base station transmits the configuration information by using the MAC layer CE, the MAC layer CE includes:
an indication bit for indicating uplink and downlink indication information of the BWP, an indication bit for indicating type information of the BWP, an indication bit for indicating identification information of whether the available BWP is allocated to the terminal, an indication bit for indicating BWP identification information, and an indication bit for indicating LCH information of the BWP;
when the indication bit for indicating the identification information of whether the available BWP is allocated to the terminal indicates that the identification information of the available BWP is allocated to the terminal, the allocation information of the available BWP of the terminal is carried in the data part.
Specifically, as shown in fig. 3, the specific bit allocation of the MAC layer CE is as follows:
the length of BWP uplink and downlink indication information (UL/DL, wherein UL represents uplink, DL represents downlink) is 1 bit; the BWP type information (P/S, wherein P denotes PBWP and S denotes SBWP) is 1bit long; whether the length of the identification information of the available BWP is allocated to the terminal is 1bit, and when the identification information of the available BWP is allocated to the terminal, the data part of the MAC layer CE can be represented as the associated information of the uplink BWP and the downlink BWP configured by the terminal in a bitmap mode; the BWP identification information (BWP index) may be a fixed bit length or a variable bit length; and LCH information for BWP.
For example, when the primary BWP and the secondary BWP are distinguished for the configured BWP, the BWP index is denoted by 3bit, 001 denotes BWP1, downlink denotes by 0, PBWP denotes by 1, identification information for allocating the available BWP to the terminal is denoted by 1, assuming that there are 3 BWPs in downlink and 4 BWPs in uplink, a 3 × 4 bitmap is used, and when the first downlink BWP, the first uplink BWP and the second uplink BWP are used, the bitmap is set in the following manner: 00100010010 or 10010000100, where the first 3 bits represent the downstream BWP and the last 8 bits are divided into two groups, each group representing an upstream BWP.
After the base station sends the configuration information to the terminal, when the terminal receives a command for activating the BWP, the corresponding BWP and the BWP associated therewith are activated.
In the embodiment of the invention, the base station determines the configuration information of the BWP for the terminal and sends the configuration information to the terminal, thereby realizing the dynamic configuration of the BWP, perfecting the communication flow and ensuring the reliability of network communication.
