Description

  The present invention relates to the field of communications, and in particular, to a method and apparatus for indicating base station capabilities.

  Due to the large number of user equipments (UEs) in existing communication systems, some low complexity and low cost UEs have been proposed to reduce system consumption. The technologies used by low-complexity and low-cost UEs are mainly the single receive antenna, reducing the size of the largest transmit block supported by the UE, half-duplex, the received signal supported by the UE And reducing the bandwidth of the transmitted signal, reducing the maximum transmit power of the UE, reducing the downlink transmission modes supported by the UE, and so on.

  In existing communication systems, some base stations support low complexity (or low cost) UEs, while some base stations support low complexity UEs. Some base stations support coverage extension, while some base stations do not support coverage extension. The UE cannot know if the base station supports a low complexity UE or if the base station supports the coverage extension. Thus, the UE blindly attempts to access the base station. If the base station does not support a low complexity UE or does not support the coverage extension, the UE consumes the power of the UE in the process of trying to access the base station and reduces the power of the UE. Cause waste.

Embodiment 1
Embodiments of the present invention provide a method for indicating base station capabilities. As shown in FIG. 1, the method includes:

S101:
The base station sends a first block of information to the UE, the first block of information carries first information, and the first information is used to indicate a capability of the base station.

  The capabilities of the base station may be that the base station does not support access by the first type of UE and the base station does not support coverage extension, or that the base station does not support access by the first type of UE. Supported, and the base station supports coverage extension, or the base station supports access by a first type of UE, and the base station does not support coverage extension, or The base station does not support access by a first type of UE, and the base station supports coverage extension.

  Alternatively, the capability of the base station is that the base station does not transmit the first system information block (SIB) or that the base station transmits the first SIB, wherein the first SIB is of the first type And the system information that at least one of the UEs or those supporting the coverage extension need to receive.

  A first type of UE is a UE that functions at a specific frequency width of a carrier, where the specific frequency width is less than the bandwidth of the carrier. The first information block is a master information block (MIB) or a first information block received when the UE accesses the base station. In existing LTE systems, the first information block received when a UE accesses a base station is the MIB.

  The base station sends a first block of information to the UE, the first block of information carries first information, and the first information is used to indicate a capability of the base station. Specifically, a description including that the first information block is MIB is provided. In the MIB, one bit carries the first information. One state of the one bit is used to indicate that the base station does not support access by a first type of UE and that the base station does not support coverage extension. Another state of the bit is a reserved state, or one state of the bit indicates that the base station does not support access by a first type of UE and the base station does not support coverage extension Another state of one bit is used to indicate that the base station supports access by a first type of UE and that the base station supports coverage extension, or The station supports access by a first type of UE and the base station does not support coverage extension, or the base station is of the first type It does not support access by UE, and the base station is used to indicate that it supports coverage extension.

  For example, if the information in one bit in the MIB is 0, it indicates that the base station does not support access by the first type of UE and the base station does not support the coverage extension. If the information in one bit in the MIB is 1, it indicates that the base station supports access by a first type of UE and that the base station supports coverage extension, The station supports access by a first type of UE and the base station does not support coverage extension, or the base station does not support access by a first type of UE and Indicates that the station supports the coverage extension. A first type of UE receives an MIB transmitted by a base station and accesses the base station by the first type of UE if one of the bits preset in the MIB is 0 It can be understood that the first type of UE does not access the base station in order to reduce the power consumption caused by blindly trying. If a first type of UE receives the base station's MIB and one of the bits preset in the MIB is one, then that bit is one indicates that the base station is of the first type. UEs of the first type access the base station if they are defined to indicate that they support the same UE and that they support the coverage extension. The fact that the bit is 1 indicates that the base station supports the first type of UE and does not support the coverage extension, or that the base station indicates the first type of UE. If it is not supported and is defined to indicate that it supports the coverage extension, the first type of UE has the same UE requirements as the capabilities provided by the base station Determine whether or not. If the requirements of the UE are the same as the capabilities provided by the base station, the first type of UE accesses the base station. If the requirements of the UE are not the same as the capabilities provided by the base station, the first type of UE does not access the base station. If the first type of UE is unable to determine according to the information in one bit in the MIB whether the capabilities provided by the base station are the same as the requirements of the UE, the first type of UE It should also be mentioned that attempts to access the base station. For example, a preset one bit in the MIB being one indicates that the base station supports at least one of a first type of UE or a coverage extension, and If the requirement of one type of UE is coverage extension, the first type of UE determines whether the base station supports the coverage extension according to the indication of information in one bit in the MIB. Can not. Thus, a first type of UE attempts to access a base station to perform communication.

  If the bit in the MIB is 0 or 1, it can be understood that the information shown is preset. Specifically, the present invention does not limit which information indicates that a bit in the MIB is 0 or 1 separately.

  Further, for example, the first information is used to indicate that the base station does not transmit the first system information block SIB, or that the base station transmits the first SIB, wherein the first SIB is: It includes system information that at least one of the first type UE or UE supporting the coverage extension needs to receive.

  For example, if the first information indicates that the base station does not transmit the first SIB, the capability of the base station indicated by the first information further indicates that the base station has a first type of UE. And if the base station does not support the coverage extension, or if the first information indicates that the base station transmits a first SIB, The capability of the base station indicated by the first information may further be that the base station supports access by a first type of UE and that the base station supports coverage extension, or that the base station supports the first type of UE. That the base station does not support the coverage extension, or the base station supports the access by the first type of UE. Razz and the base station is to support coverage extension.

  The first SIB includes one SIB or two SIBs.

  For example, the first SIB includes one SIB, which may be a machine type communication SIB. The machine type communication SIB is used to configure the system information shared by the first type of UE and the coverage extension of the base station. In the case where the machine type communication SIB can be applied to normal system coverage, both the first type UE and another type of UE receive the machine type communication SIB and the coverage extension SIB Can be.

  For example, if one bit in the MIB is 0, it indicates that the base station does not transmit a machine type communication SIB. If one bit in the MIB is 1, it indicates that the base station transmits a machine type communication SIB. Whether the base station sends a machine type communication SIB is associated with base station capabilities. If the base station does not transmit a machine type communication SIB, it indicates that the base station does not support low complexity UEs and does not support coverage extension. If the base station sends a machine type communication SIB, it indicates that the base station supports low complexity UEs, or the base station supports low complexity UEs, In addition, it indicates that coverage extension is supported.

  For example, that the first SIB includes two SIBs means that the first SIB may be a machine type communication SIB and a coverage extension SIB. The coverage extension SIB is used to configure special system information required by the coverage extension of the system. The coverage extension SIB is used for extending the coverage of the system. Both the first type of UE and another type of UE may receive the coverage extension SIB.

  Further, for example, information in two bits in the MIB is used to indicate whether the base station transmits a machine type communication SIB and whether to transmit a coverage extension SIB. Those two bits in the MIB may be bits out of the 10 reserved bits in the existing MIB. Specifically, those two bits in the MIB are separately marked as b0 and b1. Some of the values shown in Tables 1, 2, 3, and 4 for b0 and b1 to indicate whether the base station transmits a machine type communication SIB and whether to transmit the coverage extension SIB There are display methods, and the capability of the base station represented by each display style is also shown. Which bit of b0 or b1 is the upper bit is not limited in this embodiment of the present invention.

  Or

  Or

  Or

  Further, for example, if the first information indicates a degree of coverage extension supported by the base station, the capability of the base station indicated by the first information may indicate that the base station is a UE of the first type. And the base station supports coverage extension, or the base station does not support access by a first type of UE and the base station supports coverage extension. It is that you are.

  If the first information indicates a degree of coverage extension supported by the base station, the first information is an information element in a first information block or a second SIB, and the second information is Is any one of the SIBs.

  The information element is at least one of a threshold parameter, an offset parameter, a number of levels of coverage extension supported by the base station, or an amount of coverage extension corresponding to the respective level of coverage extension.

  For example, an MIB or SIB transmitted by a base station includes a bit, domain, or information element indicating a threshold parameter. The UE determines whether to access the base station according to the threshold parameter. If the parameter indicating the channel quality of the UE is greater than (or greater than) the threshold parameter, the UE accesses the base station. Otherwise, the UE does not access the base station.

  Alternatively, the MIB or SIB transmitted by the base station includes bits, domains, or information elements indicating threshold and offset parameters. The UE determines whether to access the base station according to the threshold parameter and the offset parameter. If the parameter indicating the channel quality of the UE is greater than (or greater than) the sum (or difference) of the threshold parameter and the offset parameter, the UE accesses the base station. Otherwise, the UE does not access the base station.

  Alternatively, the MIB or SIB transmitted by the base station may include a number of coverage extension levels supported by the base station, a step length corresponding to each coverage extension level, a bit, a domain, or an information element in an offset parameter. At least one of The step lengths corresponding to the coverage extension levels may or may not be the same.

  The UE determines whether to access the base station according to at least one of the number of levels of coverage extension supported by the base station, a step length corresponding to each level of coverage extension, or an offset parameter. The UE may determine the extent of coverage extension supported by the base station according to at least one of the number of levels of coverage extension supported by the base station, the step length corresponding to each coverage extension level, or an offset parameter. Can be determined. The extent of coverage extension supported by the base station is indicated by the range or maximum value of the channel quality parameter supported by the base station. If the parameter indicating the channel quality of the UE is within the range of the parameter indicating the channel quality supported by the base station or is equal to or less than the maximum value of the parameter indicating the channel quality supported by the base station. , The UE accesses the base station. Otherwise, the UE does not access the base station.

  For example, if the parameter indicating channel quality is the coverage extension value required by the PUSCH, the number of levels of coverage extension supported by the base station is 3, and the step corresponding to each coverage extension level The length is 5 dB and the offset parameter is 3 dB. For low complexity UEs, the maximum value of the channel quality parameter supported by the base station is the number of levels of coverage extension supported by the base station 3 × the step length 5 corresponding to each coverage extension level + the offset parameter 3 = 18 dB. If the coverage extension required by the PUSCH of the low complexity UE is greater than 18 dB, the UE does not access the base station. An ordinary UE states that the maximum value of the channel quality parameter supported by the base station is the number of coverage extension levels supported by the base station 3 × the step length 5 = 15 dB corresponding to each coverage extension level. Decide that. If the coverage extension value required by the ordinary UE PUSCH is greater than 15 dB, the UE does not access the base station.

  The SIB in this embodiment is at least one of SIB1 to SIB17, a new SIB type, a machine type communication SIB, or a coverage extension SIB supported by the base station in the existing LTE system.

  In the technical solution provided in this embodiment of the present invention, the base station capability is indicated in the MIB, so that the UE knows whether the base station sends the first SIB, Avoids blind detection of SIBs and reduces UE power consumption. In the solution of Embodiment 1 of the present invention, the fact that the system does not support low-complexity UEs and does not support the coverage extension may be directly or indirectly by using one bit in the MIB. This reduces bit overhead in the MIB.

  The UE may determine a degree of coverage extension supported by the system, and determine whether to access the system according to the degree of coverage extension supported by the system. This avoids wasting power trying to access the system by the UE due to the degree of coverage extension supported by the system cannot actually reach the UE's requirements. If the information received by the UE only indicates that the system does not support the coverage extension, the UE will not access the system, but in fact the UE will not be able to access the system after several attempts. Access may be made, and if the UE does not access the system, the problem of the UE not being able to fully obtain the services provided by the system is further avoided.

  A method for indicating a base station capability provided in this embodiment of the present invention is a step of transmitting, by the base station, a first information block to a user equipment UE, wherein the first information block comprises: Carrying information of the first type, wherein the first information is used to indicate a capability of the base station, wherein the capability of the base station is such that the base station supports access by a first type of UE.
