Detailed Description
The embodiment of the application can be applied to a 4G system, a 5G system or a new system generated in the future. The 4G system may be a long term evolution (Long Term Evolution, LTE) system, and the 5G system may be a New Radio (NR) system.
Fig. 1 illustrates an architecture of a communication system including an access network device and a terminal device.
A Terminal device, also called a Terminal, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, e.g., a handheld device, an in-vehicle device, etc., with a wireless connection function. Currently, some examples of terminals are: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (Mobile Internet Device, MID), a wearable device, a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, a wireless terminal in industrial control (Industrial Control), a wireless terminal in unmanned (self driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.
The Access network device in the embodiment of the application can also be called a base station or AN Access Node (AN for short), and provides wireless Access service for the terminal. The access node may specifically be a base station (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communication, GSM) or a code division multiple access (Code Division Multiple Access, CDMA) system, a base station (NodeB) in a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, an evolved base station (english: evolutional Node B, abbreviated: eNB or eNodeB) in an LTE system, or a transmission receiving point (Transmission Reception Point, TRP) in a 5G network, a base station device (gNB), a small base station device, a wireless access node (WiFi AP), a wireless interworking microwave access base station (Worldwide Interoperability for Microwave Access Base Station, wiMAX BS), or the like, which is not limited in this aspect of the application.
The term "plurality" as used herein means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used in describing various data in embodiments of the present application, these data should not be limited to these terms. These terms are only used to distinguish one data element from another.
In a Fifth Generation (5G) mobile communication New air interface (NR) system, a User Equipment (UE) and a transmission reception point (Transmission Reception Point, TRP) are connected by establishing a Beam Pair Link (BPL). One TRP may correspond to connect a plurality of UEs by allocating beams to the plurality of UEs.
Currently, when two UEs need the same beam, in order to avoid collision, TRP will generally allocate the Tx beam to one UE at random, for example, in another communication system shown in fig. 2, access network equipment is taken as TRP, UE is taken as a mobile phone, and two UEs (UE 1 and UE2 respectively) are specifically shown to be correspondingly connected to TRP, where a beam pair can be established between UE1 and TRP through Tx beam 1 or Tx beam 2; a beam pair can be established between UE2 and TRP through Tx beam 2 or Tx beam 3, and when Tx beam 2 is the best beam for both UE1 and UE2, if Tx beam 2 is configured at the same time as one end of BPL established by UE1 and UE2 with TRP, respectively, inter-UE interference will occur. To avoid inter-UE interference, TRP typically randomly chooses to assign Tx beam 2 to UE2 and Tx beam 1 to UE1; or Tx beam 2 is configured to UE1 and Tx beam 3 is configured to UE2.
The above-mentioned random allocation method is not known about the environmental condition of the UE itself, for example, the energy of the alternative beam (Tx beam 1 and Tx beam 2) of the UE1 is better than the energy of the alternative beam (Tx beam 2 and Tx beam 3) of the UE2, and the direct random selection of one of the UE1 and UE2 to occupy the Tx beam 2 may reduce the effective utilization rate of resources, which is not beneficial to the data transmission between the TRP and the UE, especially in the case that the TRP is correspondingly connected with more UEs, which may affect the overall peak speed.
Based on this, the embodiment of the application provides a beam allocation method and device, which are used for solving the problem that the effective utilization rate of beam resources is reduced in a random allocation mode in the prior art. The method and the device are based on the same inventive concept, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
For the sake of understanding the present embodiment, a beam allocation method disclosed in the embodiment of the present application will be described in detail first.
Referring to fig. 3, an embodiment of the present application provides a flow chart of a beam allocation method, which includes:
step S301, acquiring beam configuration information of N user equipments UE, where the beam configuration information includes a number of available beams corresponding to each UE in the N UEs, and receiving power information corresponding to each UE, where the receiving power information corresponding to the first UE includes a receiving power of the first UE in each available beam, and the first UE is any one of the N UEs.
In specific implementation, the beam configuration information of the UE may be obtained from uplink and downlink control information (Uplink Control Information, UCI) reported by the UE.
In step S302, when determining that each of the K available beams corresponding to the K UEs includes the first available beam, beams are allocated to the K UEs according to the number of available beams corresponding to the K UEs and/or the received power information corresponding to the K UEs.
Wherein N is a positive integer greater than 1, K is a positive integer greater than 1 and less than or equal to N, and the first available beam is an available beam with the highest received power among available beams corresponding to the UE. The UE here refers broadly to any one of the N UEs, i.e. there is one available beam with the highest received power for each UE, i.e. there is one first available beam.
In the embodiment of the application, when determining that the available beams with the maximum receiving power respectively corresponding to K UE in N user equipment UE are the same beam, beams are allocated to the K UE according to the number of the available beams respectively corresponding to the K UE and/or the receiving power information respectively corresponding to the K UE. Compared with a random allocation mode, the method has the advantages that the consideration of the number of available beams and/or the power of the available beams of the UE is added, so that the effective utilization rate of beam resources can be improved, data transmission between TRP and multiple UEs is facilitated, and the overall peak speed is improved.
Further, in an optional implementation manner, the allocating beams for the K UEs according to the number of available beams respectively corresponding to the K UEs and/or the received power information respectively corresponding to the K UEs may be implemented in the following manner:
and allocating the first available beams to second UE with the first available beam number, wherein the first available beam number is the minimum available beam number in the available beam numbers respectively corresponding to the K UEs.
In this embodiment, the available beams with the maximum receiving power corresponding to the K UEs, that is, the first available beams are allocated to the second UE with the minimum number of available beams in the K UEs, so that it can be ensured that UEs with the small number of available beams preferentially obtain beam and TRP communication, and effectively use beam resources to perform data transmission.
In implementation, if the number of available beams in the K UEs is the first number of UEs including only the second UE, the first available beams are allocated to the second UE; if the number of available beams corresponding to M UE in the K UE is determined to be the first number, the first available beams are distributed to a second UE in the M UE according to the received power information corresponding to the M UE respectively, wherein M is a positive integer greater than 1 and less than or equal to K.
Further, in an optional embodiment, the allocating the first available beam to the second UE of the M UEs according to the received power information corresponding to each of the M UEs includes:
when the receiving power of the M UE under the first available wave beams is different, the first available wave beams are distributed to a second UE with the minimum receiving power under the first available wave beams in the M UE; or alternatively, the process may be performed,
determining that the receiving power of Q UE in the M UE under the first available wave beams is first receiving power, wherein the first receiving power is the minimum receiving power in the receiving power of the M UE under the first available wave beams, distributing the first available wave beams to the second UE of the Q UE, and the receiving power of the second UE under the second available wave beams of the second UE is smaller than the receiving power of any UE except the second U of the Q UE under the second available wave beams; the second available beam of one UE is the available beam with the maximum received power except the first available beam corresponding to the UE, and Q is a positive integer greater than 1 and less than or equal to M.
When the beam configuration information of the N UEs is obtained, the available beams corresponding to any one UE in the N UEs may be ranked from large to small according to the received power of the UE under each available beam corresponding to the UE.
Based on the above, when it is determined that the available beams with the maximum receiving power corresponding to K UEs in the N UEs are all the first available beams, and the number of available beams corresponding to M UEs in the K UEs is the first number, if it is determined that the receiving powers of the M UEs under the available beams (i.e., the first available beams) with the respective corresponding ranks 1 st bit are different, the first available beams are allocated to the second UE with the minimum receiving power under the first available beams in the M UEs; if the receiving power of Q UE under the first available wave beams in M UE is judged to be the first receiving power, continuously judging that the receiving power of Q UE under the available wave beams with the respective corresponding sequence 2 bit is different, distributing the first available wave beams to a second UE in Q UE, wherein the receiving power of the second UE under the corresponding available wave beams with the sequence 2 bit is the minimum receiving power in the receiving power of Q UE under the respective corresponding available wave beams with the sequence 2 bit; or when judging that the received powers of the H UE under the available beams of the respective corresponding ranking 2 nd bit in the Q UE are all the minimum received powers of the Q UE under the received powers of the respective corresponding available beams of the ranking 2 nd bit, continuously comparing the received powers of the H UE under the available beams of the respective corresponding ranking 3 rd bit, and so on, so as to determine that the first available beam is specifically allocated to one UE.
For implementation convenience, the embodiment of the present application takes two UEs of M UEs, that is, the fourth UE and the fifth UE, respectively, with minimum received power under the first available beam as an example, and describes in detail the above method for allocating the first available beam to the second UE with minimum received power under the available beam with maximum received power except for the first available beam in Q UEs, as follows:
when determining that the received power of the fourth UE and the fifth UE in the M UEs respectively in the first available beam is the minimum, sequentially and circularly executing:
when the receiving power of the second available beam corresponding to the fourth UE is judged to be the same as the receiving power of the third available beam corresponding to the fifth UE, the available beam of the (i+1) th bit in the available beams corresponding to the fourth UE is used as the second available beam, and the available beam of the (i+1) th bit in the available beams corresponding to the fifth UE is used as the third available beam;
the second available beam is an available beam positioned at the ith position in the sequence from big to small according to the received power in the available beam corresponding to the fourth UE, and the third available beam is an available beam positioned at the ith position in the sequence from big to small according to the received power in the available beam corresponding to the fifth UE; i sequentially taking positive integers from 2 to the first number;
when the received power of the second available beam is smaller than the received power of the third available beam, the first available beam is distributed to a fourth UE; or when the received power of the third available beam is determined to be smaller than the received power of the second available beam, the first available beam is allocated to the fifth UE.
Further, if the received power of the second available beam is still equal to the received power of the third available beam when i assumes the first number, the foregoing loop is stopped, and in an alternative embodiment, the first available beam is randomly allocated to the fourth UE or the fifth UE; in another alternative embodiment, the allocation of the first available beam to the fourth UE or the fifth UE may be determined according to a preconfigured UE service priority, for example, the fourth UE currently needs to perform live broadcast in real time, and the fifth UE currently needs to perform voice call, and if the preconfigured UE service priority of live broadcast in real time is higher, the first available beam is allocated to the fourth UE. Of course, it should be noted that this is only one example. In specific implementation, the UE service priority may be set according to actual situations, which is not limited herein.
In the embodiment of the application, when the number of available beams of Q UE in K UE is the first number, namely the minimum, according to the received power of available beams of Q UE at the same sorting position in the available beams respectively, the first available beam is determined to be allocated to the second UE in Q UE, so that when the number of available beams of a plurality of UE is the same and the number of available beams is the minimum, the beams are preferentially allocated to the UE with smaller received power under the same sorting available beams in the available beams corresponding to the plurality of UE, the UE at the edge can be ensured, namely the UE with fewer available beams and lower energy can preferentially obtain the allocation of the beams, thereby better realizing the data transmission between the UE and the TRP and improving the overall peak speed.
Further, after the above method determines that the first available beam is allocated to the second UE, in an alternative embodiment, the first available beam may be deleted from available beams corresponding to N UEs, then, for the remaining N-1 UEs that are not allocated with beams, the best selected beam of each UE, that is, the first available beam, is redetermined, and then, in the above manner, the redetermined first available beam is allocated to one of the N-1 UEs, and so on, until all N UEs obtain beams for establishing beam pairs with the TRP, so as to ensure that data transmission can be performed between the TRP and the N UEs.
Further, in order to facilitate implementation, another beam allocation method is provided in the embodiment of the present application, which is applied to a 5G NR system, and it is assumed that a base station (gNB) in the 5G NR system needs to establish BPL with N User Equipments (UEs), where each UE in the N UEs corresponds to a plurality of available Tx beams, and each UE carries the number of available beams and the received power of each available beam in UCI information reported to the base station, such as reference signal received power (Reference Signal Receiving Power, RSRP), where the base station receives UCI information reported by the N UEs, and according to UCI information reported by the N UEsAnd allocating beams for N UEs. For ease of understanding, the following will refer to a plurality of UEs as N UEs, where N represents the number of UEs, 1N, and the number of available beams of the nth UE is L n 。
Another beam allocation method as shown in fig. 4 may be implemented by allocating beams to N UEs as follows:

Step S405, determining whether only one L exists in the K UEs n The smallest UE; if yes, go to step S406, if no, go to step S407;
step S406, l of K UEs is processed n,1 L of K UEs corresponding to the same beam n The smallest UE;
step S407, counting the minimum L included in the K UEs n Corresponding M UE, judge whether M UE has only one/ n,1 The smallest UE; if yes, go to step S408, if no, go to step S409;
step S408, M UEs are processedl n,1 Corresponding to the same beam being allocated to one of M UEs n,1 The smallest UE;
step S409, counting M UEs including the minimum l n,1 And corresponding Q UEs, sequentially and circularly executing: judging that Q UE comprises a plurality of l n,j When the UE is the smallest, updating the value of j to be j+1; when it is determined that l exists among Q UEs n,j With the smallest unique UE, l of Q UEs will be n,1 Assigning the corresponding identical beams to the unique UE; wherein j is more than or equal to 2 and L is more than or equal to n_Q -1，L n_Q Representing the number of any one of the Q UEs, i.e. the aforementioned minimum L n 。
Furthermore, if the value of update j is L n_Q Determining that H l are still included in Q UEs n,j The minimum UE stops the cycle, and in an alternative embodiment, H l n,j L of smallest UE n,1 Randomly assigning corresponding identical beams to one of the H UEs; in another alternative embodiment, H l may be determined based on preconfigured UE traffic priority n,j L of smallest UE n,1 The corresponding same beam is randomly allocated to one UE with highest service priority among the H UEs.
